Balancing of wheels

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

 PERFORMANCE ORDER

  1. Wheel remove from the car and establish on the balancing machine tool. There it rotates in a skilled mode. The disbalance shown thus can be counterbalanced by placing of lead cargoes.
  2. For neutralisation of last disbalance carrying out of exact balancing is necessary. A disbalance of a nave of a wheel and a brake disk are thus counterbalanced also. The wheels established on front-wheel Audi 80, by force of the engine are resulted in necessary fast rotation, showing a residual disbalance. It again counterbalance lead cargoes.
  3. At all-wheel drive cars Audi 80 for carrying out of 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 of dynamic balancing are resulted by the electric motor with a frictional disk.
