Installation structure of motorcycle steering column

Abstract

The invention discloses an installation structure of a motorcycle steering column. The steering column is arranged in a head tube in a penetrating mode and is supported with the head tube through an upper steering bearing and a lower steering bearing, and the upper port and the lower port of the head tube are both provided with a sealing fin; each sealing fin is composed of a sheet metal and a sheet rubber, wherein the sheet metal and the sheet rubber are both in a circular ring structure, and the axial leads of the sheet metal and the sheet rubber are in the same straight line; the external edge of the sheet metal is embedded into the inner ring of the sheet rubber; the external ring of the sheet rubber is integrally provided with two cowls, wherein the first cowl is embedded into the head tube and is abutted with the inner wall of the head tube, and the second cowl is pressed on the end wall of the head tube. By additionally arranging the sealing fins on the ports of the head tube, the invention ensures that the inner part of the head tube is completely isolated from outside so as to effectively prevent dust, rain and the like from entering the head tube and ensure steering bearing lubrication and the rotation flexibility of steering column. The invention has the characteristics of artful conception, simple structure, convenient installation, favorable reliability and the like and 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 the steering column of a motorcycle is shown in Figure 4. The steering column 1 is installed 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 formed by The nut 5 set on the steering column 1 is locked. 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, resulti...

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
