Brake stands for all-wheel | Diagnosis
In four-wheel drive vehicles with switchable all-wheel how to read vin numbers drive (for example, mechanically detached shafts drive axle) brake with all-wheel drive is checked off as a normal car. All-wheel drive cars with all-wheel drive can not be disabled can be checked on the brake stand only if the braking torque will not be transferred from one vehicle to another how to read vin numbers wheel that is provided only in the absence of torque on the half during the measurements.
If one of the semi-axes affects the torque from the motor vehicle or from the driving motors brake tester, this point can not be disabled at all-wheel drive will be divided between all four wheels, how to read vin numbers ie at each wheel will act fourth part of the total torque.
To clarify the effect of all-wheel drive on the results of the measurements can give the following example. Assume that the brakes on one side of the axis is normal, and on the other - there is no braking how to read vin numbers force does not develop them. In the absence of verifiable axis wheel drive vehicle braking on one side and the measurement on the brake stand having "psevdopolnoprivodny" mode, braking forces of the left and right wheels will be the same due to the even distribution of torque through the differential with a stationary shaft final drive. If you do not know that the brake on one side is defective, how to read vin numbers it can be an erroneous conclusion about the braking system.
If both wheels how to read vin numbers rotate audited axis wheel drive vehicle forward while checking the brakes on the stand, the car can "push" themselves with the roller assembly of the stand, as the torque is transmitted to the wheels of the other axes through inter-axle driveshaft. Popping can be prevented if one wheel to rotate forward, and the other - back so that the differential torque can not be transmitted to the drive shaft.
Braking torque to be measured on the wheel, rotating forward as inhibitory properties depend how to read vin numbers on the direction of rotation. This is due to the fact that the brake linings and brake drums or discs are ground only in the forward direction, so braking performance wheels rotating in the opposite direction, will be different. In connection with this measurement brakes must be repeated for each wheel so that it is rotated in the measurement in the forward direction.
To compare the braking forces of the two wheels of one axis, the same pressure on the brake pedal, as the brake force of the left and right wheels can only be measured sequentially (left once forward and once the right front). For this purpose, all-wheel drive car to be sure the brake pedal pressure sensor is connected to the pedal (the force measuring device), which allows to maintain the same pressure on the pedal with both dimensions.
SUVs may be switchable between the axles drive shaft, viskozionnuyu or hydraulic clutch on the drive shaft, and rigidly connected to the differentials on both axles drive shaft.
The hydraulic coupling can be rotated to a greater extent (soft hydraulic coupling) such that a slight rotation of the driving shaft torque is not transmitted to the other wheels, or to a lesser extent (rigid hydraulic clutch). Viskozionnaya clutch usually has the same effect as a rigid hydraulic.
Measurement of brake force-wheel drive vehicle is possible when on the half-line will not affect the braking torque or when braking torque will not be transmitted from the differential to the other axle shaft. This can be achieved when the left wheel of a vehicle how to read vin numbers rotates at the same speed as the right. The speed of rotation how to read vin numbers of the driving motors of stands for checking brake system in this case will vary, as in practice the circumference of the left wheel differs from the circumference of the right. The main reasons for this - different tread depth and a different air pressure in the tires. Therefore, the speed of rotation of the drive motors must be regulated so that both wheels rotate at the same speed. Four wheel drive vehicles with a soft hydraulic clutch on the drive shaft sufficiently indicative matches how to read vin numbers the rotational speed of the drive motors of the roller assembly as a slight rotation of the drive shaft torques or braking torque will not be transmitted via a hydraulic clutch. In this case, it suffices simply controlling the number of revolutions of the drive motors.
When checking the brake-wheel drive vehicle with a rigid hydraulic clutch in the drive axis of both wheels must be in the measurement of brake forces to rotate synchronously strictly. All-wheel drive tester IW (MAHA)
