What are the structural parts of a car?
1. Cars powered by internal combustion engines are composed of engine, chassis, body, electrical equipment and auxiliary equipment. Engine-engine chassis-transmission system, running system, steering system and braking system. Transmission system: composed of clutch, gearbox, universal transmission device and drive axle. Drive system: consists of frame, axle, wheels and suspension. Steering system: consists of steering wheel, steering gear and steering transmission device. Brake system: It consists of brake, automatic transmission device and auxiliary device of brake booster. Body-the bus is a whole, and the truck is divided into cab and cargo box. Electrical equipment-consists of power supply, starting system, ignition system, automobile lighting, signal and auxiliary electrical facilities. 2. 1. The advantage of front engine rear wheel drive (FR) is that the axle load is evenly distributed, that is, the weight of the whole vehicle is relatively balanced, so the handling stability is better. 2. Front-engine front-wheel drive (FF) can save the transmission shaft, thus solving the problem of car platform with FR layout. There is an advantage in handling, and the anti-skid ability is stronger than that of FR. 3. The rear wheel drive (RR) of the rear engine has a compact structure, and there is neither a bulky transmission shaft nor a complicated front wheel steering and driving structure. The disadvantage is that the rear axle load is large, and the steering tendency is opposite to FF in handling, that is, the high-speed cornering stability is poor and it is easy to slip. 4. The advantage of rear wheel drive (MR) with mid-engine is obviously that the axle load is uniform and it has very neutral handling characteristics. The disadvantage is that the engine occupies the engine room space, which reduces the space utilization and practicality. 5. Four-wheel drive Whether it is a front, middle or rear engine, four-wheel drive can be used. Because all four wheels have power, the utilization rate of adhesion is the highest, but its obvious disadvantage is that it is heavy and takes up a lot of space.
