In Wheel and Tyre Assembly, two types of imbalances occur:
IMPORTANCE OF BALANCING
At a speed of 60 km/h, the centrifugal force of a 10 g imbalance is equal to that of a sledge hammer. When the speed of the vehicle is more, forces would be severe. Poor Balancing / Improper Balancing are dangerous. It can create following impact:
- Induce stress level in suspension components and bearing areas
- Vibrations in Steering Wheel and it can be felt inside the cabin
- • Brake Wear
- • Tyres wear and tear will be more
- • Braking distance increases
With the balancing weights of BHRATWEIGHTS axes are brought back to balance.
CORRECTING IMBALANCE ON TYRES AND RIMSf
The imbalance of the tyre and rim is measured by the balancing machine and the problem is corrected using BHARATWEIGHTS WHEEL BALANCE WEIGHTS.
Procedure involves rethreading the tyre on the rim until the sources of imbalance on the rim and tyre are opposite each other. The residual imbalance is compensated with BHARATWEIGHTS WHEEL BALANCE WEIGHTS.
A form defect of the rim can only be compensated by uneven tyre deflection. Smooth running optimisation involves placing the heavy and hard area of the tyre opposite the highest area of the rim. The residual imbalance is compensated with BHARATWEIGHTS WHEEL BALANCE WEIGHTS.
OPTIONS FOR BALANCING
Balancing by knock-on or Clip Weights for both levels. This type requires least mass for balancing. Most car manufactures use this option.
Balancing with the use of Sticker (Adhesive) Type Balance Weights in both the areas. The weights are affixed to the inner or outer plane of the wheel in the outer most positions.
Both Sticker (Adhesive) Weights are affixed on the inside of the wheel rim. The external balance level is in this case transferred back behind the spokes.
The outer balancing level is relocated inside and the Sticker (Adhesive) Weight is attached in the rim centre in the brake disc area. A knock-on or safety weight is attached at the inner wheel rim flange.
Sticker (Adhesive) Wheel Balance Weight is used at the outside of the rim. It is attached to the outer most position of the wheel. A knock-on or clip-on weight is used at the inner wheel rim flange
At the outer side of the wheel rim, a knock-on or clip-on weight is used at the rim flange. Sticker (Adhesive) weight is used on the inside of the wheel rim. The weight is affixed to the rim centre in the outer most position
If uncoated balancing weights are mounted on a rim, it may come to contact corrosion. Contact corrosion occurs when metals with different nobility are in close contact. The more noble metal enhances the corrosion of the less noble metal. The condition for this process is a corrosive media between the two metals, like rain water or simple humidity. Coated balancing weights preserve any rim from damage due to contact corrosion. The high quality OEM coating protects the weight optimally against environmental influences, even under extreme conditions. See comparison coated / uncoated weights in self-test on the right side. All weights are correspondingly subjected to OEM specifications 600 hours salt spray test according to DIN 9227 and ADTM B 117-73.
BBW does various surface coatings for Wheel Balance Weights as per OE Customer requirement viz., Geomet, Atotech, Dorken, Magni, Silver Synthetic Powder Coating, e-Coating + Top Paint
INSTALLATION OF KNOCK-ON WEIGHTS
SELECTION OF THE CORRECT WEIGHT
Prior to installation, select the appropriate weight from the BHARATWEIGHTS range on the basis of the rim shape. The choice is determined by the rim design. The rim flange thickness varies (steel rim/aluminium rim) and different rolling processes are used. Put the weight beside the rim flange before installation to check the shape.
POSITIONING THE WEIGHT
Put the weight to the calculated place. Before knocking the weight on the rim, make sure that the clip is correctly touching the rim flange.
APPLICATION OF THE WEIGHT
After positioning of the weight, apply it with an adequate tool (such as mounting pliers or hammer). To install the weights, no more than two forceful knocks should be used. A higher number of knocks can damage the coating of the weights.
POSITIONING OF WHEEL WEIGHT
After the installation, please ensure a tight fit of the weight.
After positioning of the weight, apply it with an adequate tool (such as mounting pliers or hammer). To install the weights, no more than two forceful knocks should be used. A higher number of knocks can damage the coating of the weights
