Automobile wheel hub balance strip

Abstract

The invention discloses a vehicle wheel hub balancing strip. The invention comprises a balancing strip main body (1) and an installing part arranged on the main body and used for installing the main body at the inner side of the wheel hub; the balancing strip main body (1) is a flexible outer sleeve with the both ends to be closed and a pipe cavity (2) inside; metal grains (3) are arranged in the pipe cavity (2); the volume of the residual space which is not occupied by the metal grains (3) in the pipe cavity is 1 / 3 to 1 / 2 of the total volume of the pipe cavity (2); the diameter of the metal grain (3) is equal to or smaller than 400 meshes; the metal grain (3) is a stainless steel grain or iron sand grain. The invention has the advantages that the cost is low, and the default that the wheel hub balancing because the non-balancing point test exists the error or the balancing strip equipment error is not ideal can be made up through effective automatic calibration (adjustment) of the wheel hub balancing.

Description

Technical field:

[0001] The invention relates to an accessory of an automobile wheel hub, in particular to an automobile wheel hub balance bar for making up for the defect of the dynamic balance of the automobile wheel hub. Background technique:

[0002] In the manufacturing process of automobile wheels, due to the limitation of processing technology, materials and other factors, the wheels have congenital defects in dynamic balance, especially the cast wheels, which currently account for 90% of the global wheel market, due to the dense structure of some parts inside the castings, Some parts are relatively loose, which leads to the uneven weight of the cast wheel hub from the center to the rim, which causes severe vibration, abnormal sound, tire wear and steering wheel vibration during driving. In order to make up for the defect of dynamic imbalance when the wheel hub rotates, and to avoid the car's severe vibration, abnormal sound, tire wear and steering wheel vibration, wh...
