Quick answer. Before comparing any of the fifteen units, decide sectioned or working for each line you order. A sectioned unit is a cutaway on a stand that a group studies by looking, identifying and measuring clearances; a working trainer needs a drive or pump, the correct fluid, a reservoir and a floor that tolerates a leak, and in return lets students operate it, measure pressures and find faults. One of each teaches more than two of either. Then quote every code with its full product name, because ATM-0001 to ATM-0015 share their prefix with the automobile testing machines range.
Fifteen trainers in two subjects. Steering and suspension, ten units: a sectioned front suspension unit, a McPherson strut type suspension trainer, power steering trainers including a self-contained version and a rack and pinion version, sectioned power steering components, sectioned power steering hydraulic pumps, a sectioned steering gears set, and sectioned rack and pinion and worm and roller gearboxes. Braking, five units: a hydraulic dual circuit brake system trainer with fault facility, a hydraulic brake chassis trainer, a master cylinder trainer and sectioned single stage and tandem master brake cylinders.
A code warning first, because it could cost you the wrong delivery. The codes in this listing run ATM-0001 to ATM-0015. A different range in this catalogue, automobile testing machines, uses the same prefix starting at the same number - so ATM-0001 is a sectioned front suspension trainer here and a fogging tester there, and ATM-0004 is sectioned power steering components here and a flammability tester there. Quote the code and the full product name together and ask for both to be confirmed on the proforma invoice. We are having the codes corrected; until then the product name is the reliable identifier.
You will also see the words "for engineering schools" at the end of every name, in several cases run together with the word before it. That is a fault in how our product names were assembled rather than anything about the products, and it is being cleaned up.
Every item in this listing is one of two things, and the difference decides the price, the services it needs and what it can teach. Settle it for each item before ordering.
| Sectioned unit | Working trainer | |
|---|---|---|
| What the student does | Looks, identifies, measures clearances, understands construction | Operates it, feels the effect, measures pressures, finds faults |
| What it needs | A stand and good lighting. Nothing else | A drive or a pump, the correct fluid, a reservoir, and somewhere that tolerates a leak |
| What it cannot do | Show behaviour under load or pressure | Show internal construction, because the parts that matter are inside the castings |
| Ask | Is the cut surface finished, polished and labelled? Can the parts still move by hand? | What drives it, what fluid and how much, what pressure it reaches, and whether faults can be introduced |
The honest recommendation: a laboratory that can afford one of each learns more than one that buys two of either. A sectioned pump explains why the working rig behaves as it does, and the working rig makes the sectioned pump worth studying.
Six of the ten steering units are about hydraulic power assistance, which is the right subject for a workshop servicing the vehicles on the road today, and the sectioned pumps and gears are the best way to teach it because the interesting part is invisible on an assembled vehicle. Ask what pressure the working units reach, what fluid they take, how the fluid is contained and whether a drip tray and spare seals come with them - a teaching steering rig will leak eventually.
Two choices of gear type are offered and they are not interchangeable as teaching objects. Rack and pinion is what a student will meet on light vehicles; worm and roller and recirculating-ball gears are what they will meet on heavier vehicles and older ones. Buy the one your syllabus names, and if the programme covers both, say so and we will quote both sectioned gearboxes rather than one.
And the gap worth naming: there is no electric power steering unit in this listing. Electrically assisted steering is now standard on most new light vehicles, it fails and is diagnosed quite differently from a hydraulic system, and a programme written in the last few years almost certainly covers it. If yours does, tell us and we will quote for it rather than letting a hydraulic rig stand in for it.
The dual circuit brake system trainer with a fault facility is the most valuable unit in this listing for a trade programme, because it lets a student produce a symptom - a long pedal, a pull to one side, a failed circuit - and then find the cause. Ask how many faults it can introduce, whether they are switched or made by hand, and whether an instructor fault key is supplied. The sectioned master cylinders alongside it answer the question the fault trainer raises: what is actually happening inside.
Three practical rules go with any hydraulic brake trainer, and they are worth printing and fixing to the wall beside it.
Brake fluid is not a benign liquid. Conventional glycol-based brake fluid strips paint, is harmful if swallowed and irritates skin and eyes. Gloves and eye protection when bleeding, a tray under the work, and a rule that spills are cleaned immediately rather than left on a painted bench.
Brake fluid absorbs water from the air, and water lowers its boiling point. A trainer that has stood on a bench for two years holds fluid that is nothing like fresh fluid, and a system bled with it behaves badly and teaches badly. Ask what fluid specification the unit takes, keep a sealed stock of it, and change the fluid in the trainer on a stated interval - which is also exactly the lesson the student needs about real vehicles. And never mix fluid types: glycol and silicone specifications are not compatible.
Ask for written confirmation that any friction material supplied is asbestos-free. Older brake linings and pads contained asbestos, asbestos is banned or strictly controlled in most countries, and a teaching rig is handled and dusted by students. Ask us, get it in writing, and do not accept friction material of unknown origin on a trainer that will be stripped and reassembled by a class.
One more gap to name: there is no anti-lock braking or stability control unit in this listing. Those are electronic systems that are diagnosed with a scan tool rather than a spanner, and a current syllabus will include them. Tell us if you need them.
A chassis-based brake trainer and a suspension unit are floor items, not bench items. Ask for the mass, the footprint, whether castors are fitted and whether the frame needs anchoring, and plan a route by which they can be brought into the room. Ask also what guarding covers any moving part and whether a working rig has an accessible emergency stop.
Then count the practical groups in one session and divide. A sectioned unit can be studied by a group of five around it; a fault-finding exercise on a brake trainer occupies one group for most of a session. That number, rather than the specification, decides how many units a department should buy.
For each unit: whether it is sectioned or working; what drives it and what fluid it takes, with quantity and specification; pressures reached; fault-insertion arrangement and instructor key; whether the cut surfaces are finished and labelled; the exercise or worksheet set supplied; mass, footprint, castors and anchoring; guarding and emergency stop on working rigs; confirmation that friction materials are asbestos-free; consumables and spares with prices, which here means seals, hoses, fluid, pads and shoes; nominal voltage, frequency and plug pattern where a unit is powered; and the warranty, commissioning and local service position. For any certification stated here, contact us for the latest copies of the relevant certificates before you tender on it.
Related ranges: automobile equipments for components and system models, cutaways models for cut-section engines and chassis, the automobile workshop range for engine rigs and workshop fit-out, and hydraulics and fluid mechanics trainers for the hydraulic principles behind power assistance. The full set is listed under engineering apparatus. For a quotation, tell us the destination country, which steering and braking systems your syllabus examines, the class size in one session, and whether you need the electronic systems that are not in this listing.
The page singles out the hydraulic dual circuit brake system trainer with fault facility as the most valuable unit for a trade programme, because a student can produce a symptom - a long pedal, a pull to one side, a failed circuit - and then trace the cause. Before ordering, ask how many faults it can introduce, whether they are switched or made by hand, and whether an instructor fault key is supplied. The sectioned single stage and tandem master brake cylinders are its natural partners: they show what is happening inside while the trainer shows the effect.
Because two ranges share the prefix. The automobile testing machines range also starts at ATM-0001, so ATM-0001 is a sectioned front suspension trainer in this listing and a fogging tester there, and ATM-0004 is sectioned power steering components here and a flammability tester there. Until the codes are corrected, the product name is the reliable identifier. Quote the code and the full product name together on your enquiry, and ask for both to be confirmed on the proforma invoice so the right unit is built and shipped.
They are not interchangeable as teaching objects. Rack and pinion is what students meet on light vehicles; worm and roller and recirculating-ball gears are what they meet on heavier and older vehicles. Buy the sectioned gearbox your syllabus names. If the programme covers both types, say so when you enquire and both sectioned gearboxes will be quoted rather than one. The sectioned steering gears set and the rack and pinion power steering trainer sit alongside them if you also want the assisted version on a working rig.
No, and the page says so plainly. Six of the ten steering units cover hydraulic power assistance, but electrically assisted steering is now standard on most new light vehicles, fails differently and is diagnosed differently, so a recently written programme almost certainly includes it. Likewise there is no anti-lock braking or stability control unit; those electronic systems are diagnosed with a scan tool rather than a spanner. If your syllabus covers them, tell us and we will quote for them instead of letting a hydraulic rig stand in.
Three rules worth fixing to the wall beside it. First, conventional glycol-based brake fluid strips paint, is harmful if swallowed and irritates skin and eyes: use gloves and eye protection when bleeding, a tray under the work, and clean spills at once. Second, the fluid absorbs water from the air, which lowers its boiling point, so keep a sealed stock of the specified fluid and change it on a stated interval - and never mix glycol and silicone types. Third, ask for written confirmation that any friction material supplied is asbestos-free.
Count the practical groups in one session and divide, because that number decides the quantity more than any specification. A sectioned unit can be studied by a group of five standing around it; a fault-finding exercise on a brake trainer occupies one group for most of a session. Space matters too: the chassis-based brake trainer and the suspension unit are floor items, not bench items. Ask for the mass, footprint, castors and anchoring, plan the route into the room, and check the guarding and emergency stop on any working rig.

Specifications for every unit - drive, fluid, pressures reached, mass, footprint and fault-insertion arrangement - are confirmed in writing on the quotation. For certificates, standards or approvals, contact us for the latest copies of the relevant certificates. No price is quoted on this page. Listing note: codes ATM-0001 to ATM-0015 repeat the prefix and numbering of the automobile testing machines range, and the words 'for engineering schools' are appended to every product name, in places run together with the word before; both are being corrected, so confirm the code and full product name on the proforma invoice.
These are finished front end units of vehicle that are perfect for showing the task and collaboration of guiding and suspension components. Using these coaches, understudies might be presented to the capacity of the stabilizer, safeguards, controlling linkages, suspension frameworks, zones of arrangement and modification, task of brakes and the sky is the limit from there
McPherson Strut Type Suspension Trainer , specialized showing gear for designing
This is as of now, without question, the most broadly utilized front suspension framework in autos of European beginning. It is straightforwardness itself. The framework fundamentally includes a swagger sort spring and safeguard combo, which rotates on a swiveling appendage on the single, bring down arm. At the best end there is a needle roller bearing on some more modern frameworks. The swagger itself is the heap bearing part in this get together, with the spring and safeguard only playing out their obligation as restrict to really holding the auto up. The controlling apparatus is either associated straightforwardly to the lower safeguard lodging, or to an arm from the front or back of the shaft (for this situation). When you steer, it physically curves the swagger and safeguard lodging (and subsequently the spring) to turn the wheel.

The unit is precisely separated as to obviously demonstrate all the interior parts. Every segmented zone are painted and shading coded to take into consideration simple ID of parts. Directing apparatus activity can be exhibited by utilizing the hand wheel to turn the instrument. Henceforth, it is conceivable to see plainly how the pinion draws in the rack and makes it move when the directing wheel is turned. The pole on which the rack is machined has two circular couplings at its end and these are thusly associated with the controlling arms. The unit is provided on an exquisite wooden base.
Worm and Roller Gearbox (Sectioned Units), technical teaching equipment for engineering
Trainer - This steering gear uses an hourglass-shaped worn (the cam) mounted between opposing taper roller bearings. The outer race of the bearings is located in the end plate flange and in a supporting sleeve at the input end of the worm shaft. Shims, incorporated between the end plates and housing, are used for adjusting the taper roller bearing preload and for centralizing the worm relative to the rocker shaft.
A roller follower having two or three teeth engages with the worm teeth and is carried on two sets of needle rollers supported on a short steel pin, which is located between the fork arm an integral part of the rocker shaft. To reduce frictional losses, the needle rollers are replaced by ball races, which support radial loads and also end thrust. The rocker shaft is supported on two plain bushes located in the steering box and other in the top cover plate. A shouldered screw located in a machined mortise to T slot at one end of the rocker shaft, absorbs end thrust in both directions on the rocker shaft.
In order to adjust the depth of mesh of the worm and roller, the steering wheel is moved to the mid-position of the number of turns of the steering wheel from lock to lock. The end thrust shouldered screw is screwed until all free movement is taken up and then the lock nut is tightened to reduce offset distance. The cam is centralised relative to the rocker shaft roller so that there is an equal amount of backlash between the roller and worm at a point half a turn of the steering wheel at either side of the mid-position. Any adjustment necessary is carried out by removing the shims from one end plate and adding the same to the existing shims at the other. The forward and reverse efficiencies of the worm and roller gear are respectively 73% and 48%, which are slightly lower than the cam and peg type of gear. These efficiencies to some extent depend upon the design. To obtain higher efficiencies a needle or taper roller bearing can be used between the rocker shaft and housing instead of the usual plain bush type of bearing.
