Vibration reducer groove tight sealing structure

Abstract

The invention discloses a vibration reducer groove tight sealing structure, belongs to the technical field of vehicles, guarantees tight sealing of a vibration reducer, can enlarge a gap between a thread at the top of the vibration reducer and a side deck under the condition of not influencing the length of a fastening thread, and provides swing space to the vibration reducer. The device comprises a pin shaft, a support sleeve, a groove end cover, a boss nut, and a T-shaped sealing ring cover. The T-shaped sealing ring cover is mounted in a vibration reducer lifting lug, so that the installation of a sealing ring is optimized, and the assembly efficiency and the assembly precision are improved. A boss grooving nut is screwed into a thread part of the pin shaft to press the groove end cover, and is transferred into a steel wire pin to finish fastening; a concave-convex design is adopted to enlarge the gap between the thread part of the pin shaft and the side deck; and meanwhile, cooperation can be formed with the T-shaped sealing ring cover to provide the space for swing of the vibration reducer and to limit the swing angle.

Description

technical field [0001] The invention belongs to the technical field of vehicles and relates to a shock absorber groove fastening and sealing structure, that is, a fastening cooperation device between a boss nut and a groove end cover. Background technique [0002] Our factory adopts the shock absorber fastening and sealing structure, the thread fastening length is longer, and the compression degree of the joint bearing sealing ring of the shock absorber is different. During use, since there is no corresponding limit for the installation of the sealing ring cover, the sealing ring cover is installed too deep during assembly, and the sealing ring is pressed too tightly, resulting in increased rotational resistance of the shock absorber; the distance from the top of the thread at the pin end to the side deck If it is close to the side deck, it is easy to collide with the side deck, which may cause the anti-loosening steel wire pin to fall off, resulting in the failure of the fa...

AI Technical Summary

Problems solved by technology

During use, since there is no corresponding limit for the installation of the sealing ring cover, the sealing ring cover is installed too deep during assembly, and the sealing ring is pressed too tightly, resulting in increased rotational resistance of the shock absorber; the top of the thread at the pin end is farther away from the side deck close to the side deck, it is easy to collide with the side deck, which may cause the anti-loosening steel wire pin to fall off, resulting in the failure of the fastening of the shock absorber
