Vehicle wheel bearing assembly

Abstract

The invention discloses a vehicle wheel bearing assembly and belongs to the field of vehicle design. The vehicle wheel bearing assembly comprises a first bearing part and a second bearing part. Upper surfaces of the first bearing part and the second bearing part are provided with sine surfaces of the same cycle length. The cycle length of the sine surfaces is correlated with the sprung mass resonance frequency of a vehicle of a predetermined type. The first bearing part and the second bearing part provide travel section for the vehicle at the same time, wherein the first bearing part is designed to enable a left tire of the vehicle to travel, and the second bearing part is designed to enable a right tire of the vehicle to travel. The vehicle wheel bearing assembly solves the problem that the stress relief of a vehicle plate spring is insufficient when the bumpy road test on vehicles of various types is conducted on the same bumpy road, and can carry out the bumpy road test by determining a suitable bumpy road for a vehicle based on the sprung mass resonance frequency of the vehicle, thereby achieving the effect of fully releasing stress of a vehicle plate spring.

Description

technical field [0001] The invention relates to the field of vehicle design, in particular to a wheel bearing assembly. Background technique [0002] After the vehicle assembly is completed, the vehicle manufacturer will conduct a bumpy road test on the vehicle to release the stress of the vehicle leaf spring. [0003] At present, the same bumpy road is used for various types of vehicles, but the parameters corresponding to different models of vehicles may also be different. Using the same bumpy road to test various types of vehicles on bumpy roads may cause insufficient stress release of the vehicle leaf spring. Insufficient stress release of the leaf spring of the vehicle may cause large changes in body posture, changes in vehicle four-wheel alignment parameters, and incorrect vehicle direction during vehicle driving. Contents of the invention [0004] An embodiment of the present invention provides a wheel bearing assembly. Described technical scheme is as follows: ...

AI Technical Summary

Problems solved by technology

Both the upper surfaces of the first bearing part and the second bearing part form a sinusoidal curved surface with the same period length. Since the period length of the sinusoidal surface is related to the resonant frequency of the sprung mass of a predetermined type of vehicle, it solves the problem that the same bumpy road is currently used for Various types of vehicles, but the parameters corresponding to different vehicle models may also be different. Using the same bumpy road to test various types of vehicles on bumpy roads may cause the problem of insufficient stress release of the vehicle leaf springs. The resonant frequency of the sprung mass determines the bumpy road that is more suitable for the vehicle. The bumpy road test is performed to fully release the stress of the vehicle leaf spring.
