Motorcycle front vertical pipe steering lockhole sealing structure

Abstract

The invention discloses a motorcycle front vertical pipe steering lockhole sealing structure. The motorcycle front vertical pipe steering lockhole sealing structure comprises a front vertical pipe and a steering lock, wherein the steering lock is arranged on a mounting support arranged on the outer wall of the front vertical pipe; the front vertical pipe and the mounting support are respectively provided with a steering lockhole and a through hole with corresponding positions; after the steering lock is locked, a lock cylinder of the steering lock penetrates the through hole and the steering lockhole to stretch into the vertical pipe; the position, corresponding to the steering lockhole, of the outer wall of the front vertical pipe is fixedly connected with a sealing pipe; one end of the sealing pipe is circumferentially and hermetically connected with the steering lockhole, and the other end of the sealing pipe extends to the end face, near the front vertical pipe, of the through hole or extends into the through hole; the steering lock is provided with a lock cylinder shaft sleeve arranged outside the lock cylinder in a sleeving way; the lock cylinder shaft sleeve extends into the sealing pipe; and a sealing ring abuts against the outer end face of the sealing pipe. The motorcycle front vertical pipe steering lockhole sealing structure can prevent water from flowing into the front vertical pipe and eliminate the defect of steering clamping stagnation caused by the fact that the internal part of the vertical pipe and a lower steering bear are rusted.

Problems solved by technology

At present, the front standpipe steering lock and the front standpipe of motorcycles generally adopt a direct fit method, and the seal between the steering lock hole and the steering lock is not well considered. When the car is washed, there will be water from the unsealed steering lock hole. This will cause rust inside the front standpipe and the lower steering bearing, or dust will enter the front standpipe and destroy the lubrication performance, resulting in the defect of steering sticking, which will affect the normal use of the motorcycle and even bring danger
