Balancing of wheels

Neotbalansirovannye wheels are shown by vibration of a steering or a potryakhivaniye before. Both effects are especially strongly appreciable at operedelenny speeds. The reason – in non-uniform distribution of weight on a wheel. Therefore wheels should be отбалансированы statically and dynamically. For this purpose there are two methods:


  1. Wheel remove from the car and establish on the balancing machine. There it rotates in a skilled mode. The imbalance which was showed thus can be counterbalanced by placement of lead cargoes.
  2. For neutralization of the last imbalances carrying out exact balancing is necessary. Imbalances of a nave of a wheel and a brake disk are thus counterbalanced also. The wheels established on front-wheel Audis 80, are given by force of the engine in necessary fast rotation, showing a residual imbalance. It again counterbalance lead cargoes.
  3. At all-wheel drive Audi 80 cars for carrying out exact balancing it is necessary to lift all 4 wheels.
  4. In the absence of own drive back wheels of front-wheel models for carrying out dynamic balancing are given by the electric motor with a frictional disk.
