Problems solved by technology

Usually, the bottom of the cover covers the entire end surface of the shaft ring. Since the cover is a stamping part, the machining accuracy is low and the bottom surface is uneven. When it is fitted to the end surface of the shaft ring, it will have a great influence on the height deviation of the bearing and cause a large swing of the bearing end surface. Large, which in turn affects the installation accuracy and performance of the thrust bearing, and in severe cases will greatly reduce the service life of the bearing

Embodiment Construction

[0019] The present invention will be further explained below in conjunction with accompanying drawing.

[0020] like figure 2 shown. The thrust bearing for a commercial vehicle steering axle of the present invention includes an outer cover 96, a shaft ring 09, a seat ring 08, a rolling element 04 and a cage. The outer diameter of the thrust bearing is ΦD30-100mm, and the cage can be a stamped steel cage or a nylon cage. When the full roller, full ball or damping bearing structure is used, the cage is also unnecessary. Wherein, the inner diameter of the seat ring 08 has a seat ring annular sealing ring 48, and the seat ring annular sealing ring 48 is an annular rubber sealing ring. The inner diameter of the shaft ring 09 is a shaft ring annular sealing ring 48, and the shaft ring annular sealing ring 48 is an annular rubber sealing ring. There is a step at the chamfer of the large end surface of the shaft ring 09, which is convenient for the edge of the outer cover to fit o...

Abstract

The invention relates to a thrust bearing with a novel structure for a steering axle of a commercial vehicle. The invention belongs to the technical field of rolling bearings. The invention is mainly used for solving the problem that due to the existence of an outer cover in the thrust bearing for the steering axle, the mounting precision and the using performance are affected. The thrust bearing is mainly characterized by comprising an outer cover, a shaft ring, a seat ring, a sliding ring, a lantern ring, or a rolling body and a retaining frame, wherein a seat ring annular seal ring is arranged at the inner diameter of the seat ring; a shaft ring annular seal ring is arranged at the inner diameter of the shaft ring; a step is arranged at the chamfered part of the large end face of the shaft ring; the outer cover has a bottom face which is narrower than the large end face of the shaft ring, one end of the outer cover is lower than the outer end face of the seat ring, the outer bottom face at the other end of the outer cover is lower than the outer end face of the shaft ring, one end face of the outer cover is jointed with the oblique slope of the seat ring, and the bottom face of the outer cover is jointed with the step of the shaft ring; and a cylindrical seal ring is arranged between the shaft ring and the seat ring. The thrust bearing provided by the invention has the characteristics of good sealing and using performance and good precision in mounting and use, and is mainly used for the steering axle of the commercial vehicle.

Description

technical field [0001] The invention belongs to the technical field of rolling bearings. It specifically relates to a series of thrust bearings with a new structure for commercial vehicle steering axles, which are used for the steering support of the front axle of the automobile. Background technique [0002] At present, the bearings used for the steering support of the front axle of automobiles include thrust ball bearings, thrust roller bearings, and damping bearings. The bearing is installed on the kingpin of the steering axle and rotates at a low speed as the front wheels turn. [0003] The steering bearing generally has an outer cover 93, and the shaft ring 02, the seat ring 01, and the rolling element 04 are installed in the outer cover, such as figure 1 shown. Usually, the bottom of the cover covers the entire end surface of the shaft ring. Since the cover is a stamping part, the machining accuracy is low and the bottom surface is uneven. When it is fitted to the e...
