The truck consists of four parts: engine, chassis, body and electrical system. The operation of the truck is mainly carried out by the engine and the chassis, where the chassis includes the transmission system, driving system, steering system and brake system.
The principle of truck operation: When we start the car, the engine will generate power and transmit the power to the gearbox. The power will pass through the gears in the gearbox to convert the high-speed low-torque power into low-speed high-torque power, and then transmit it to the The rear axle is driven, and the rear axle is driven to drive the rear wheels to rotate, so a car moves.
Functions and main components of each part:
A. Engine: The power source of the car. Its function is to burn fuel to generate power, and then drive the wheels through the drive train to drive the car.
B. Chassis: It is introduced by transmission system, driving system, steering system and braking system.
Transmission system: transmits the power of the engine to the drive wheels, mainly including clutches, gearboxes, drive shafts, and drive axles.
Driving system: It connects the various assemblies and components of the car into a whole and supports the whole car to ensure the normal running of the car. Mainly including frame, front axle, wheels, suspension.
Steering system: to ensure that the car can travel in the direction selected by the driver during driving, mainly including the steering control mechanism, steering gear, and steering transmission.
Braking system: to slow down and stop the car and ensure the car to park reliably. It mainly includes brake control mechanism, brake and transmission device.
C. Body: the place where the driver works and loads goods. Includes cab and compartment.
D. Electrical equipment: the electrical system that assists the driver in driving the car, including batteries, starting systems, lighting equipment, instruments, etc.
