4. The manipulation and stability of the car

The stability of the car's control means that the driver can drive in the direction of the driver in the direction given by the driver in the direction of the driver without feeling nervous and fatigue. Ability.

The manipulation of a car refers to the response ability of the car to the driver's steering instruction, which directly affects driving safety. The pneumatic and elasticity of the tire, the stiffness of the suspension device, and the location of the car center of gravity have an important impact on the performance.

The stability of the car is the ability to restore the original motion state after the car is disturbed by the outside world, as well as the ability to resist the overwriting and side slip. Car control stability usually uses the stable steering characteristics of the car to evaluate. There are three situations: insufficient steering, excessive steering, and neutral steering characteristics. Cars with deficiencies to steering characteristics will increase the turn radius when they are accelerated around the corner of the steering wheel, and the turning radius will increase; under this condition, the turning radius will gradually decrease under this condition; there is a neutral steering. Car -based cars remain unchanged. Easy -to -control cars should have appropriate deficiencies to prevent the cars from sudden ending.

For cars, side stability is particularly important. When the car is driving, turning on the horizontal ramp, and being affected by other side force, it is prone to skid or side flip. The lower the height of the car center of gravity, the better the stability. The appropriate front -wheel positioning angle makes the car the ability to automatically return and maintain linear driving, which improves the stability of the car in line. If the vehicle speed is too high, the speed is too fast during turning, the horizontal ramp angle is too large, and the load is too loaded, it is easy to cause the car's side slip and rollover.

5. The smooth driving of the car

The smoothness of the car is the performance of the vibration environment of the occupant during driving. This is closely related to the chassis parameters, body geometric parameters, car dynamicity and control of the car.

During the driving process of the car, due to the unevenness of the road, it will cause the vibration of the car, making passengers feel fatigue and uncomfortable, and the goods are damaged. In order to prevent the above phenomenon from occurring, the speed of the vehicle has to be reduced. At the same time, vibration will also affect the life of the car. During the driving, the degree of rigidity of the road surface is called the smooth driving of the car.

For car driving smooth physical quantities evaluation indicators, passenger cars and cars use "comfort to reduce boundaries" vehicle speed characteristics. When the speed of the car exceeds this boundary, it will reduce the comfort of ride, making people feel tired and uncomfortable. The higher the limit of this world, the better the smoothness.

Cargo vehicles adopt the "fatigue-reduce the boundaries of work". The inherent frequency of the car body can also be used as a smooth evaluation indicator. Starting from comfort, the body's inherent frequency is 600-850Hz.

High -speed cars, especially cars, require excellent driving smoothness. The elasticity of the tires, the suspension device with superior performance, the vibration performance of the seat, and the non -reed quality as possible, can improve the smoothness of the car.
