Wheel assembly and whole vehicle axle assembling method

Abstract

The invention provides a wheel assembly and whole vehicle axle assembling method. In the prior art, a wheel assembly is installed on a whole vehicle axle, due to assembly tolerance and radial runout of the wheel assembly, radial runout fluctuation of the wheel assembly of the whole vehicle is large in the running process of the whole vehicle, and finally a steering wheel of the whole vehicle shakes, wheels deviate and NVH performance is poor. In the invention, the above problems are solved. The method comprises the following steps of S1, acquiring radial runout data of the wheel assembly to beloaded in a rotating process; S2, extracting an angle corresponding to the highest point of an average radial runout amplitude curve of the wheel assembly from the acquired runout data of the wheel assembly; S3, obtaining a position of the radial runout highest point of the wheel assembly according to the angle corresponding to the highest point of the average radial runout amplitude curve of thewheel assembly; and S4, assembling the wheel assembly and a whole vehicle axle in a matched mode, and meanwhile ensuring that the highest point of radial runout of the wheel assembly is always located at the highest point of the vertical ground of the wheel assembly in an assembling process.

Description

technical field [0001] The invention relates to the technical field of assembly of automobile parts, in particular to a method for assembling a wheel assembly and an axle of a complete vehicle. Background technique [0002] In the vehicle assembly technology, the processing size of the center hole of the wheel assembly is A(+d / 0), and the processing size of the axle on the vehicle that matches the wheel assembly is A(0 / -d). When it is on the axle of the vehicle, due to the action of gravity, the wheel assembly and the axle of the whole vehicle are in contact with the highest point of the vertical ground, and a gap of 2d is generated at the lowest point. , when the highest point H of the radial runout of the wheel assembly is located at the lowest point of the vertical ground of the wheel assembly and is assembled with the axle of the whole vehicle, the wheel assembly of the whole vehicle produces the maximum runout Δ 1 +2d, as in Figure 1-Figure 3 Therefore, during the dri...
