Embodiment Construction

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0036] The present invention aims at the deficiencies and deficiencies of the prior art, and provides a method for effectively evaluating the reliability of the riveting of the hub bearing unit. Since the main function of the riveting structure is to provide a reliable pre-tightening force for the hub bearing unit, lock the inner ring of the bearing, and prevent its loose. Based on the functional analysis of the riveting structure, the reliability of the riveting is evaluated ...

Abstract

The invention relates to the technical field of automobile hub bearing units, and discloses a hub bearing unit riveting reliability evaluation device. The device comprises an axial loading device anda hub bearing fixing device, and is characterized in that the hub bearing fixing device is provided with a transverse loading device, and the transverse loading device is perpendicular to the output end of the axial loading device; and a detection device is arranged on the axial loading device. The invention discloses a method and device for evaluating the riveting reliability of a hub bearing unit. The method starts from the actual use working condition of the hub bearing unit; limit use conditions of the wheel hub bearing in a loading state are simulated; the displacement sensor is used forvisually and clearly representing the variation of the position of the inner ring, so reliability judgment is carried out, evaluation indexes are clear, the evaluation method is simple, efficient andhigh in accuracy, and the blank of visual evaluation standards and methods for the riveting reliability of the hub bearing unit is filled up.

Description

technical field [0001] The invention relates to the technical field of automobile hub bearing units, in particular to a method and device for evaluating the riveting reliability of a hub bearing unit. Background technique [0002] At present, riveting technology has been widely used in the design and manufacture of hub bearing units. However, there is no evaluation method for the riveting reliability of hub bearing units. According to experience, technicians can indirectly control the diameter and thickness of the riveting surface. Control the quality of riveting, but the diameter and thickness of the riveting surface are greatly affected by the machining size of the inner flange parts, so this control method has a large quality hidden danger; although, before and after riveting, the axial preload of the raceway is tested. However, this test can only reflect the effect of riveting on the preload of the raceway, and cannot reflect the axial locking of the hub bearing by the r...
