Motorcycle steering column installation structure

Abstract

The invention discloses a motorcycle steering column installation structure. The steering column is installed in the head tube, and is supported by the upper and lower steering bearings and the head tube, and sealing sheets are arranged at the ports at the upper and lower ends of the head tube. . The sealing sheet is composed of a metal sheet and a rubber sheet, the metal sheet and the rubber sheet are ring structures, and the axis lines of the two are on the same straight line; the outer edge of the metal sheet is embedded in the inner ring of the rubber sheet, and the rubber sheet The outer ring of the sheet is integrally formed with two lips, wherein the first lip is embedded in the head tube and abuts against the inner wall of the head tube, and the second lip is pressed against the end wall of the head tube. In the present invention, by adding a sealing sheet at the port of the head tube, the inside of the head tube is completely isolated from the outside, effectively preventing dust, rainwater, etc. , simple structure, convenient installation, good reliability and other characteristics, it can be used on various types of motorcycles.

Description

technical field [0001] The invention relates to a motorcycle component, in particular to a mounting structure for a motorcycle steering column. Background technique [0002] At present, the installation structure of motorcycle steering column is as follows: Figure 4 As shown, the steering column 1 is pierced in the head tube 2, and is supported by the upper and lower steering bearings 3, 4 and the head tube 2, and the upper steering bearing 3 is locked by the nut 5 set on the steering column 1. Since the end of the head tube 2 is not effectively sealed, dust and rainwater in the air can easily enter the inside of the head tube 2, causing the upper and lower steering bearings 3 and 4 to fail to lubricate and cause premature wear, so that the steering column 1 is prone to Shaking makes the driving operation laborious, the driver is prone to fatigue, and there are certain potential safety hazards; the large dust residue may also cause the steering to be stuck, resulting in inf...

Problems solved by technology

Since the end of the head tube 2 is not effectively sealed, dust and rainwater in the air can easily enter the inside of the head tube 2, causing the upper and lower steering bearings 3 and 4 to fail to lubricate and cause premature wear, so that the steering column 1 is prone to Shaking makes the driving operation laborious, the driver is prone to fatigue, and there are certain potential safety hazards; the large dust residue may also cause the steering to be stuck, resulting in inflexible steering of the front of the motorcycle, which is very dangerous in emergency situations during motorcycle driving. It is easy to cause safety accidents
