Faults chassis and suspension

These failures result from overloading the vehicle, reckless driving on bad roads or due to violations of adjustment and wear. The main signs of malfunction of chassis: slip the car right or left of straight-line motion, wagging front steering wheels at high speeds, increased tire wear front wheels, roll, rocking the car and knock on suspensions. Disposed car occurs most often due to unequal pressure in the tires of wheels, but also because of the deflection angles of the installation of right and left wheels of the nominal values. Slip can also occur as a result of deformation front suspension arm or bend the beam front axle. Wag observed when the front wheels worn or damaged bearings front wheel hub, a big backlash in the joints of steering tie rods, high clearances in bearings, bushings and pins, and as a result of an imbalance of wheels and tires. Increased tire wear front wheels occurs when the air pressure in tires, other than the established norms, violation of the collapse or toe, unsatisfactory performance shock absorbers, increasing backlash in the bearings of the wheels, increasing the imbalance of the wheels. Roll the car and rocking motion on rough roads are the result of breakage of springs or unilateral Air suspension springs. Rocking the car to go there in case of failure of shock absorbers or leakage of fluid from the working tank. Knocking suspension begins with wear sleeves in conjunction with the spring legs, or in conjunction with the suspension damper. Angles of the front wheels is checked and adjusted to an optical or mechanical stand measuring device which acts on the lateral surface of the tire or wheel rim. The sequence of testing and adjusting the angles of the wheels on the stand is determined by instruction of the stand. Checking and correction of the convergence front wheels are now mostly produced in specialized positions in the service station. Condition Suspension checked for maintenance inspection, and mount them - application effort. Care for shock is to check the fastenings, timely replacement of the rubber bushings fixtures as they wear. Particular attention should be paid to control leakage. If the shock lose cushioning properties and leak-proof (there is leakage of fluid), its repair. The serviceability of a tire test in each type of service because of the tires depends largely on safe operation of the vehicle. By the operation does not allow tires that have holes or cuts tire bundle framework, tread, tire failure side, through cracks in the sidewall, and tire tread wear unacceptable, which is estimated to rise to the tread wear indicators, or the depth of the groove in the center of the running tread, which should not be less than 1.6 mm for passenger cars and at least 1 mm for trucks. Damaged tires and tubes should be removed from the wheels and sent to the repair or reconstruction. Punctures cameras can be eliminated in a way, using elektrovulkanizatorom or curing of briquettes and raw rubber.
