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
The present invention relates to a kind of motor bike member, particularly the mounting structure of direction column of motorcycle.
Background technology
At present, the mounting structure of direction column of motorcycle as shown in Figure 4, direction post 1 is located in the head tube 2, and by 2 supportings of upper and lower two steering bearings 3,4 and head tube, and goes up steering bearing 3 and locked by the nut 5 of suit on the direction post 1.Because the end of head tube 2 does not effectively seal, koniology and rainwater are easy to enter into the inside of head tube 2, make upper and lower steering bearing 3,4 lubrication failures, cause wearing and tearing in advance, direction post 1 easily produces and rocks like this, make driver behavior require great effort, there is certain potential safety hazard in the chaufeur fatiguability; Bigger dirt slag may cause also and turn to clamping stagnation that it is dumb to cause headstock to turn to, in case of emergency abnormally dangerous in the motorcycle driving process, causes safety misadventure easily.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of installation structure of motorcycle steering column, enters head tube inside effectively to prevent impurity such as dust, rainwater.
Technical scheme of the present invention is as follows: a kind of installation structure of motorcycle steering column, comprise direction post, head tube, last steering bearing, following steering bearing, nut and seal strip, wherein the direction post is located in the head tube, and, be provided with seal strip in the port of described head tube upper and lower end by upper and lower two steering bearings and head tube supporting.
Adopt above technical scheme, port at the head tube upper and lower end is embedded seal strip, the sealing sheet is covered the slit between head tube and the steering bearing, make impurity such as koniology and rainwater can not enter head tube inside, thereby guaranteed the lubricated of upper and lower two steering bearings, prolonged the service life of steering bearing, and prevented that the direction post from shaking or clamping stagnation, eliminated potential safety hazard.
Above-mentioned seal strip is made of sheetmetal and sheet rubber, and sheetmetal and sheet rubber are circular ring structure, and both axial lines are on same straight line; The outer rim of described sheetmetal embeds the inner ring of sheet rubber, is formed with two lips in the outer ring of sheet rubber, and wherein first lip embeds in the head tube, and with the inwall butt of head tube, second lip is pressed on the end wall of head tube.Above structure is simple and practical on the one hand, be easy to make, and on the other hand, first lip and second lip combine, and can make that head tube is inner isolates fully with the external world, and sealing effectiveness is good.
Above-mentioned sheet rubber in the raw the time angle between described first lip and second lip be acute angle, like this when seal strip is installed to the port of head tube, first, second lip of sheet rubber deforms, first lip tightly butt is lived the inwall of head tube, and second lip is adjacent to the end wall of head tube, thereby further improved the leak free effect.
Install, help the seal strip location for convenience, be provided with lining between above-mentioned seal strip and steering bearing, an end of this lining and steering bearing are fitted, and the other end of lining and the sheetmetal of seal strip fit.
Beneficial effect: the present invention sets up seal strip by the port at head tube, head tube inside is isolated fully with the external world, prevented that effectively dust, rainwater etc. from entering in the head tube, guaranteed the rotation alerting ability of the lubricated and direction post of steering bearing, have be skillfully constructed, characteristics such as simple in structure, easy for installation, good reliability, on various types of motor bikes, all can use.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Fig. 3 is the structural representation of seal strip among the present invention.
Fig. 4 is the structural representation of background technology.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
As Fig. 1, Fig. 2, shown in Figure 3, the present invention is by component set-ups such as direction post 1, head tube 2, last steering bearing 3, following steering bearing 4, nut 5, seal strip 6 and linings 7, and wherein direction post 1 and head tube 2 all adopt prior art, and its structure is not done at this and given unnecessary details.Described seal strip 6 is made of sheetmetal 61 and sheet rubber 62, and sheetmetal 61 and sheet rubber 62 are circular ring structure, and both axial lines are on same straight line.The outer rim of described sheetmetal 61 embeds the inner ring of sheet rubber 62, be formed with two lip 62a, 62b in the outer ring of sheet rubber 62, these two lip 62a, 62b all are obliquely installed with respect to the axial line of seal strip 6, sheet rubber 62 in the raw the time angle between the described first lip 62a and the second lip 62b be acute angle, this acute angle preferred range is 60~80 °.
From Fig. 1, Fig. 2, Fig. 3 as can be known, steering bearing 3 in the pipe of head tube 2 upper ends, press-fiting, lower surface of steering bearing 3 is spacing by the step surface in the head tube 2 on this.Seal strip 6 is installed at mouth of pipe place in head tube 2 upper ends, sealing sheet 6 is set on the direction post 1 by the centre hole of sheetmetal 61, and be provided with lining 7 between seal strip 6 and the last steering bearing 3, fit in the upper surface of the lower surface of this lining 7 and last steering bearing 3, the lower surface of sheetmetal 61 fits in the upper surface of lining 7 and the seal strip 6, the upper surface of this sheetmetal 61 is compressed by nut 5, and described nut 5 is threaded on the direction post 1.
