Embodiment Construction

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. 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.

[0034] Cars have higher and higher requirements for wheel speed signals. As a key component for collecting wheel speed signals, magnetic encoders are increasingly used in cars. At present, magnetic encoders are mainly arranged on the end faces of wheel hub bearings in cars. However, the magnetic encoder has poor resistance to muddy water impa...

Abstract

The invention discloses a sealing structure for the end of a hub bearing and an automobile, and relates to the technical field of hub bearing sealing. The sealing structure comprises a steering knuckle, the hub bearing, a driving shaft and a blocking piece; an annular boss is arranged on the inner end surface of the steering knuckle; the outer ring of the hub bearing is connected with the steering knuckle; the driving shaft is connected with the inner ring of the hub bearing; the blocking piece and the end of the hub bearing are arranged in a spaced mode, the driving shaft is sleeved with the blocking piece, an annular groove is formed in the blocking piece, and the annular groove and the annular boss are matched to form the labyrinth type sealing structure. The annular groove and the annular boss are matched to form the labyrinth type sealing structure, when a vehicle runs, muddy water cannot directly pass through the labyrinth type sealing structure, it can be guaranteed that a magnetic encoder is not directly impacted by the muddy water, the possibility that the magnetic encoder makes direct contact with the muddy water is reduced, and the service life of the magnetic encoder is ensured.

Description

technical field [0001] The invention relates to the technical field of hub bearing sealing, in particular to a sealing structure at the end of a hub bearing and an automobile. Background technique [0002] The main function of the 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. The hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings. The two sets of bearings are combined into one. It has good assembly performance, can omit clearance adjustment, light weight, compact structure, large load capacity and Free from maintenance and other advantages, it has been widely u...
