Embodiment

[0026] Example: such as figure 1 , figure 2 and image 3 As shown, a method for detecting the operation of a wheel hub bearing unit follows the following steps:

[0027] Step 1: During random inspection, the hub bearing unit 7 is first placed on the flaw detector to ensure that the inspected product has no processing defects. Then connect the wheel hub outer ring connecting flange 6 without processing defects through the rotating shaft 4 and the cushioning suspension simulation component 8, and then connect and fix the hub bearing unit 7 with the rotating shaft 4 in a splined socket first, and then connect with the wheel hub The outer ring connecting flange is 6-phase flange socket fixed, and at the same time, the bolt connection and fastening of the hub bearing unit 7 and the imitation hub connecting seat 9 are completed. The imitation wheel hub connection seat 9 adopts the motor connection flange plate 10 which is an integrated structure with the drive variable frequency...

Abstract

The invention relates to a method for detecting the operation of a hub bearing unit, which belongs to the technical field of hub bearing unit performance testing. The connection flange of the outer ring of the hub passes through the rotating shaft and is connected and fixed with the simulation component of the cushioning suspension, and then the hub bearing unit is first connected with the rotating shaft. The shaft is spline-type socketed, and then fixed with the connecting flange of the outer ring of the wheel hub, and at the same time, the bolt connection and fastening of the wheel hub bearing unit and the imitation wheel hub connection seat are completed. The driving frequency conversion motor is used to simulate the running speed of the vehicle, and the speed can be changed in real time, so that the hub bearing unit can be simulated for N hours in the hub running simulation box, and at the same time, the vibration cylinder can be stretched irregularly to improve the harsh operating environment. After completing the simulation test detection of different speeds, the wear condition and assembly clearance of each component of the hub bearing unit are numerically detected. It has the advantages of compact structure, complete functions, convenient use, intuitive detection and long service life. Improve the safety of vehicle operation.

Description

technical field [0001] The invention relates to the technical field of performance testing of a hub bearing unit, in particular to an operation detection method of a hub bearing unit. Background technique [0002] The main function of the automobile hub bearing is to bear the load and provide precise guidance for the rotation of the hub. It bears both axial load and radial load, and is a very important component. Traditional automobile wheel bearings are composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of the bearings are all carried out on the automobile production line. This structure makes it difficult to assemble in the automobile production plant, high in cost, and poor in reliability. Moreover, when the automobile is maintained at the maintenance point, the bearing needs to be cleaned, oiled and adjusted. [0003] The hub bearing unit is developed on the basis of standard angular contact ball ...
