Abstract
Provided is a balance weight used for automobile tyre, which is mounted to wheels in a felting manner. Corresponding to inner diameter varieties of wheels provided in different standards, said balance weight is prone to bend and extend, with improving its applicability and adhesion characteristic.
Description
Technical field
The present invention relates to a kind of mode with bonding and be installed in the balancing weight that is used for automobile tire on the wheel, especially, corresponding to the variation of the wheel internal diameter under the various criterion, this wheel balance weight that is used for automobile tire is easy to bending and extension.
Background technique
Usually use prefabricated molds to make automobile tire through sulfidation.In the process that forms tire, lose the weight balancing of tire probably, just, produce the skewness of tire weight inevitably.When tyre rotation,, the imbalance of this tire weight reduces the comfortable of vehicle ride thereby causing the vibrations on chassis.And excessive or endurance longly also can be continuously applied fatigue on the chassis when this vibrations; Simultaneously, thereby can occur the stability reduction that the slit causes motor live time to reduce and drives between the each several part, therefore increase the possibility of security incident.
For addressing the above problem, a kind of equilibrate counterweight with suitable weight is installed on the even point of wheel, all should put the imbalance of compensation tire at this, thereby keeps the weight distribution of tire equably.
More specifically, automobile tire be installed in around the wheel of axletree coupling and inflation be tubeless shape.At this moment, balancing weight can be installed in the suitable position of wheel inner edge, and tire surrounds described wheel, therefore compensates the imbalance of tire weight.
