Description

Technical Field

[0001] The utility model relates to a power-assisted transmission nut with an integrated bearing, belonging to the technical field of automobile steering control. Background Art

[0002] For the current rear-wheel steering system of automobiles, the bearings and nuts are separate and need to be assembled and fixed later. At the same time, the bearings and nuts manufactured by different suppliers have assembly tolerances during assembly, and the two parts need to be constantly debugged to meet the corresponding requirements, which increases the assembly cost and time cost. At the same time, it also makes the bearings and nuts assembled together not stable enough, posing a safety hazard.

[0003] The present application seeks to protect a power-assisted transmission nut with an integrated bearing, wherein the bearing of the power-assisted transmission nut with an integrated bearing is fixed on the outer side of the nut, and the bearing and the nut can be formed as one piece without assembly, and the inner side of the nut is provided with an internal thread, and the front end and the rear end of the nut are provided with a sealing gasket placement groove, and the sealing gasket placement groove is used to place the sealing gasket, and a screw is provided in the nut, and the rotation of the screw can adjust the relative position of the bearing and the nut. The power-assisted transmission nut with an integrated bearing for protection in the present application does not require subsequent assembly, thereby improving the tolerance stability of the system. The integrated bearing nut can be quickly assembled with the screw and the housing, thereby improving the stability of the system. In addition, the power-assisted transmission nut with an integrated bearing has a reasonable structural design, a stable and reliable structure, and is suitable for promotion and use.
