Cut-Section Model Of Demonstration Chasis Working

he model is made out of full size original used car/van chassis consisting of the four stroke mpfi petrol engine. The cut section model is constructed such that all the following systems can be demonstrated in working conditions.

Engine:

maximum parts and accessories of an engine like of the cylinders, cylinder head, inlet and exhaust manifolds, common rail, cmp sensor, throttle body, ecu, self-starter, alternator, water pump, radiator, etc, are sectioned to show the internal constructional details.

this complete sectioned models is coupled with 1/4 hp 220/230v a. C single phase motor through a reduction drive unit. By running the motor the complete working details of the individual parts, different mechanisms can be demonstrated as the model is running at a very low speed (about 15 to 20 rpm).

Transmission system:

it consists of a clutch and gearbox assembly, the casing of which is suitably cut to demonstrate its operation. The hydraulic circuit from the pedal to the clutch is active and will help to demonstrate the response of hydraulic systems. The gearbox is coupled to differential gear box with an axle and the different coupling used for this transmission can be demonstrated. The differential gear box is also cut so as to clearly to demonstrate its complete operating principle. The gear shifting including the forward and reverse gear operation can be clearly shown. The speed variation and the rotation of the differential gear box can be seen while gear shifting.

Fuel system:

the fuel tank is cut to expose the mounting of the level sensor and tank module and the position of fuel section.

Exhaust system:

it consists of exhaust manifold and silencer in cut section to explain internal construction.

Lubrication system:

it consists of the engine lubrication system along with the lubrication oil pump.

Suspension system:

this will explain both the hydraulic suspension systems at the front and the leaf spring suspension at the rear. One of the hydraulic arrangements of suspension mechanism is highlighted (with shock absorbers) and explained cut sectionally.

Braking system:

this hydraulic circuit of the hydraulic braking mechanism is operational. The movement of the brake shoes on operating the pedals can be seen in the area where the brake drum is cut (front wheel brake drum). The rear brakes cannot be demonstrated hydraulically but it is shown using hand braking system that is by using cables.

Steering mechanism:

this can be seen and included in the steering wheel, steering gear and coupling at the wheels.

Electrical system:

the electrical system gives a complete idea of the electrical system and circuit of a car. It has been provided with sectionised battery and terminals are provided to connect another working battery to show the working of the individual parts and accessories such as a sectionised self starter, dynamo, wiper motor, cutout, distributor, horn relay, etc. , and working of head light brake light, side indicator, horn, parking lights, spark in spark plugs, etc.
