Problems solved by technology

Since the outer cover 93 seals the outer end surface of the shaft ring 02 without a narrow bottom structure, the outer cover 93 and the seat ring 02 have adverse effects on the assembly accuracy
Since the end face of the outer ring 94 is not provided with a sealing structure, there is a problem that dirt enters the bearing and affects the service life of the bearing

Embodiment Construction

[0018] The present invention will be further explained below in conjunction with accompanying drawing.

[0019] Such as figure 2 shown. A thrust needle roller combined bearing for an automobile steering knuckle of the present invention includes a shaft ring 03, a rolling element 05, a cage 07, a needle roller 14, a shaft ring O-shaped sealing ring 48, an inner spacer ring 63, a sealing ring assembly 68, and an outer cover 95 and outer ring 96. Wherein, the inner diameter of the shaft ring 03 has a shaft ring O-ring seal 48, the shaft ring O-ring seal 48 is an annular rubber seal ring, and the cage 07 is an engineering plastic cage. There is a step at the chamfer of the large end face of the shaft ring 03, which facilitates the edge of the outer cover 95 to fit on the step, and eliminates the adverse effect of the outer cover 95 on the assembly accuracy. The outer cover 95 has a bottom surface narrower than the large end surface of the shaft ring 03 , the end surface of the...

Abstract

The invention relates to a thrust roller pin combination bearing for an automobile steering knuckle, and belongs to the technical field of rolling bearings. The thrust roller pin combination bearing mainly solves the problems that in an existing thrust bearing for a steering knuckle, an adverse effect is generated on assembly precision, pollutants enter the bearing, and consequently the service life is influenced. The thrust roller pin combination bearing is mainly characterized in that an outer cover, an outer ring, a shaft ring, a rolling body, a shaft ring O-shaped sealing ring, a roller pin, a holder and an inner ring spacer are included; a step is arranged on the chamfer of the large end face of the shaft ring; the outer cover is provided with a bottom face narrower than the large endface of the shaft ring, and the bottom face of the outer cover is attached to the step on the chamfer of the shaft ring; the end face of the outer cover is lower than the end face of the shaft ring;the rolling body and the holder are arranged between the shaft ring and the outer ring; and a sealing ring assembly is arranged on the end face of the outer ring. The thrust roller pin combination bearing has the advantages that by means of the combination bearing, on the premise of not reducing the sealing performance of the outer ring, the adverse effect of the outer cover and a seat ring to theassembly precision is eliminated, the sealing performance is improved, and the bearing weight is reduced; and the thrust roller pin combination bearing can be used for series automobile steering knuckles.

Description

technical field [0001] The invention belongs to the technical field of rolling bearings, and in particular relates to a novel structural bearing for an automobile steering knuckle, which is used for the kingpin support of the automobile steering knuckle. Background technique [0002] The steering knuckle is the hinge for the steering of the wheel, and its style is mainly fork. In order to make the steering flexible, a thrust bearing, or a damping bearing, or a sliding bearing, or a drawn outer ring needle roller bearing is installed between the lower ear of the steering knuckle and the fist part of the front axle. The bearing is mounted on the king pin of the steering knuckle and swings at a low speed as the front wheels turn. [0003] With the improvement of stamping and drawing process, a combined bearing for automobile steering knuckle has evolved. This type of bearing is composed of needle roller bearings and thrust roller bearings, usually consisting of seat ring 01, s...
