More than 80 brake steering wheel jitter, brake steering wheel jitter
Normal brakes when the steering wheel wobbling because of large amount of brake pads and brake disc kuang, simple said is the brake disc, brake pads and brake discs between kuang is after the driver hit the brakes brake pedal there will be a slight shaking response, after the jitter through feedback to reverse disc drive system, so the driver will have the feeling of brake wheel jitter.
Besides the speed higher than 80 or more brake wheel wobbling or have resonance phenomenon, in most cases is caused by tire deformation or vehicle transmission system, first check the balance weight on the wheels, if you lose balance weight loss is likely to bring the steering wheel to produce jitter of the fault, and note that after adding balance weight, Both longitudinal and transverse vibration amplitude must be less than 0.3mm.
Then check whether the positioning Angle of the front wheel and the front bundle value meet the standard requirements, raise the vehicle to check the feedback of the front axle test wheel and the dynamic balance of the wheel; The main purpose of the wheel dynamic balance is to prevent the vehicle at high speed when the tire jitter, so as to further drive the steering wheel together jitter, after all, the front wheel is a rotating wheel, the dynamic balance requirements are very high; If the above inspection and debugging did not solve the problem, it is necessary to check the vehicle's suspension system, such as the lower arm, pull rod ball head is loose.
The principle of braking is to convert the kinetic energy of the vehicle into heat energy and consume it. This kinetic energy comes from the power provided by the engine and is provided by fuel combustion. It can reduce the time and frequency of braking reasonably and appropriately while maintaining a safe driving distance.
