The chassis is made of sheet metal plate and steel tubes welded between themselves, arranged so as to support all mechanical parts and the body.
It is protected against corrosion and rust by an electro-galvanic zinc-plating and then furnace-painting with epoxy polyester powders.
Front wheels steering device
The chassis – aligned with the wheels – lodges a particular oscillating support equipped with a lever with grooved hole; a steering bar is connected to the lever and it controls the wheel steering hubs. The hubs are connected between themselves by a second bar.
The guiding trolley grooved pin is engaged inside the grooved hole.
Motor and Transmission
The car is driven by a 48 V DC motor with reducer, which transmits the motion to the driving wheel on the rear axle by a chain drive. The motor is lodged on the car rear side and transmits the motion to left wheel. The motor is complete with electrical brake equipped with unlocking lever.
The transmission is equipped with a chain tensioner device allowing to recover chain cession (elongation).
It is made of squared section steel drawing. It is equipped with fixing plates to be fixed to the chassis.
The axle is manufactured to receive the transmission on both wheels: wheel carrier hubs and drive crown wheels are mounted on the edges.
Chain tensioner devices are mounted on it: one per each side.
The car is equipped with a device, made up of three front photocells and rear reflectors. The device triggers when the car approaches the other car preceding it, and acting on the engine electrical brake. A set of three photocells is mounted onto a revolving support, controlled by a cable connected to a steering hub. This allows the device to operate along the bends, too.
The electric system components are partly assembled on chassis front side and partly on chassis rear side. The access to the electric system is possible after lifting the complete body.
The car is equipped with front and rear bumpers: they consist of a steel core and a polyurethane foam coating. They can bear small crashes only. Collisions at a speed over 1.5 m/sec. (5.4 km/h) may deform them permanently.
The body is made of PRFV (fibreglass), finished with spray painting and completed with moulding, accessories, lights, etc.
The body is fixed to the chassis, on the right side, by a couple of hinges, and on the left side by a screw. By removing the screw, it is possible to lift the body on the hinged side. Then, using a proper bar kept lifted, it is possible to reach the electric system, the transmission and other devices.
The front side of the car is equipped with two lights with 24V 10W lamps, and the rear side with four small 24W 5W lights.
Manual Start Button
This device, placed on the body rear side, includes a key switch and a button. The latter allows to manually move the car for maintenance operations.
This device guides the car along the rail and directs the front wheels. It is complete with lateral rubbing contacts taking current from conductors placed on rail side.
A rubbing contact mounted on the right side, onto an arm, excludes the collision-proof system in the station. That is why, a proper contact track is located in the station area.
