A bearing box and its application

Abstract

The invention relates to a bearing box and application thereof. The bearing box comprises a box body which comprises a box body inner ring and a box body outer ring, wherein the box body inner ring and the box body outer ring are respectively in a cylindrical shape of which both ends are open, the box body inner ring is arranged in the box body outer ring, taper roller bearings are arranged on both ends of the box body and between the box body inner ring and the box body outer ring, sealing devices are arranged on the outer sides of the taper roller bearings, adjusting nuts are arranged on the outer sides of the sealing devices, screw threads are formed on the inner walls of the adjusting nuts, other screw threads are formed on the outer wall of the box body inner ring, the adjusting nuts are connected with the box body inner ring through the screw threads, and the taper roller bearings comprise bearing outer rings and bearing inner rings. The invention further discloses the application of the bearing box to an automobile steering knuckle. The bearing box has the advantages that the sealing performance is good, lubricating oil is unlikely to leak and can be gear oil, and the bearing box can be repeatedly used, is less prone to damage, can be conveniently removed and installed and easily steered, and does not need to be maintained for years.

Description

technical field [0001] The invention relates to a bearing box and its application, in particular to the application of a bearing box instead of a sliding bearing in a steering knuckle of an automobile. Background technique [0002] The existing automobile steering knuckles all use sliding bearings, that is, copper sleeves, which cooperate with the steering knuckle kingpin to realize steering. The steering knuckle of this structure will lead to heavy steering and easy grease leakage. It is necessary to add lubricating oil frequently. The oil can only use grease; since the copper sleeve and the steering knuckle kingpin are not sealed, mud, sand and dirty water can easily penetrate into the gap between the copper sleeve and the steering knuckle kingpin. The lubricating oil groove of the copper sleeve is installed on the upper and lower sealing surfaces of the steering knuckle. The grease nipple is easy to be blocked, and the copper sleeve and the steering knuckle kingpin are ea...

Problems solved by technology

[0002] The existing steering knuckles of automobiles all use sliding bearings, namely copper sleeves, which cooperate with the kingpin of the steering knuckle to realize steering. The steering knuckle of this structure will lead to heavy steering and easy leakage of lubricating grease. It is necessary to add lubricating oil frequently to lubricate the steering knuckle. Oil can only use lubricating grease; since the copper sleeve and the steering knuckle kingpin are not sealed, mud, sand, and dirty water can easily penetrate into the gap between the copper sleeve and the steering knuckle kingpin. The grease nipple is easy to block, and the copper sleeve and steering knuckle king pin are easy to wear, and the service life is short

In addition, it is troublesome to adjust the gap between the upper and lower sealing surfaces of the steering knuckle
