Description
Technical field
The utility model belongs to the inverted front shock absorber field on motor bike, particularly relates to the guide on a kind of inverted front shock absorber and front fork tube mounting structure.
Background technology
Be well known to those skilled in the art, inverted front shock absorber is the vitals on motor bike, and guide and front fork tube mounting structure are the important component parts on inverted front shock absorber.As shown in Figure 1, existing guide and front fork tube mounting structure comprise guide 1 and front fork tube 2, and wherein the bottom of guide 1 centre hole is inserted on front fork tube 2 top, and the axial line of these two parts needs in theory on same straight line; The diameter of described guide 1 centre hole bottom is less than the diameter of its bottom, is formed with a step surface between these two sections.Upper shaft sleeve 3 and Lower shaft sleeve 4 is installed with vertically in the bottom of guide 1 centre hole, separated by lining C between these two axle sleeves, and Upper shaft sleeve 3 is by the step surface axial limiting between guide 1 centre hole bottom and bottom, and Lower shaft sleeve 4 is by packing ring 5, oil sealing 6 and collar 7 axial limiting, and packing ring 5, oil sealing 6 and collar 7 are arranged on the bottom of described guide 1 centre hole from top to bottom successively.Meanwhile, the top bearing fit of Upper shaft sleeve 3 and Lower shaft sleeve 4 and described front fork tube 2.
In the fabrication process, we find that existing structure exists following defect:
Because Upper shaft sleeve 3 and Lower shaft sleeve 4 are arranged on the bottom of guide 1 centre hole, and Upper shaft sleeve 3 is by the step surface axial limiting between guide 1 centre hole bottom and bottom, so just needs to have higher right alignment between the bottom of guide 1 centre hole and guide 1.In order to ensure above-mentioned right alignment specially, manufacturing cost will be increased in manufacturing process and reduce work efficiency, if the right alignment between the bottom of guide 1 centre hole and guide 1 cannot be guaranteed, will cause the axial line of the axial line of front fork tube 2 and guide 1 after assembling not on same straight line, front fork tube 2 will be caused like this to move up and down in process clamping stagnation occurs, thus cause operation to have some setbacks, and then cause traveling comfort not good.
Utility model content
Technical problem to be solved in the utility model is to provide the guide on a kind of inverted front shock absorber and front fork tube mounting structure, front fork tube is moved up and down in process run smooth and easy.
The technical solution of the utility model is as follows: the guide on a kind of inverted front shock absorber and front fork tube mounting structure, comprise guide (1), front fork tube (2), Upper shaft sleeve (3) and Lower shaft sleeve (4), wherein the bottom of guide (1) centre hole is inserted on the top of front fork tube (2), and the axial line of these two parts is on same straight line; It is characterized in that: described Upper shaft sleeve (3) is coaxially solidly set on the upper end of front fork tube (2), and with the centre hole bearing fit of described guide (1); Described Lower shaft sleeve (4) is fixedly mounted in the large footpath section of guide (1) centre hole lower end, with described front fork tube (2) bearing fit the while of this Lower shaft sleeve; Step surface between described Lower shaft sleeve (4) upper surface and guide (1) centre hole bottom path section and lower end large footpath section is close to, the lower surface of this axle sleeve and packing ring (5) near, and packing ring (5) and oil sealing (6) and collar (7) are arranged in the large footpath section of described guide (1) centre hole bottom from top to bottom successively, and collar (7) is stuck in the annular mounting groove of this large footpath section.
Compared with conventional confguration, improvements of the present utility model are: 1, the bottom of guide (1) is adjusted to path section, its lower end is adjusted to large footpath section, and Lower shaft sleeve (4) is installed in this large footpath section, and Lower shaft sleeve (4) and guide (1) bearing fit; 2, by the position of Upper shaft sleeve (3) by original guide (1) being adjusted on present front fork tube (2), and Upper shaft sleeve (3) in the utility model with guide (1) bearing fit; 3, owing to there is relative movement in this configuration between Upper shaft sleeve (3) and Lower shaft sleeve (4), so just no longer the lining in conventional confguration is needed.
Adopt above technical scheme, the utility model is mainly through the installation site of adjustment Upper shaft sleeve, not only reduce difficulty of processing like this, and effectively can ensure that front fork tube moves up and down in process and clamping stagnation does not occur, run smooth and easy, thus just solve large problem by little change, there is good practicality.
For the ease of installing, the upper end of described front fork tube (2) has an annular groove, and described Upper shaft sleeve (3) is arranged in this annular groove.
Beneficial effect: the utility model is mainly through the installation site of adjustment Upper shaft sleeve, not only reduce difficulty of processing like this, and effectively can ensure that front fork tube moves up and down in process and clamping stagnation does not occur, run smooth and easy, thus just solve large problem by little change, there is good practicality.

Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 2, the guide on a kind of inverted front shock absorber and front fork tube mounting structure, formed primarily of guide 1, front fork tube 2, Upper shaft sleeve 3, Lower shaft sleeve 4, packing ring 5, oil sealing 6 and collar 7.Wherein, the bottom of guide 1 centre hole is inserted on the top of front fork tube 2, and the axial line of these two parts is on same straight line.Upper shaft sleeve 3 is coaxially solidly set on the upper end of front fork tube 2, and with the centre hole bearing fit of guide 1.As preferably, the upper end of front fork tube 2 has an annular groove, installs a Upper shaft sleeve 3 in this annular groove.
The bottom of guide 1 centre hole is path section, and the lower end of this guide 1 centre hole is large footpath section, has a step surface between this large footpath section and above-mentioned path section.Lower shaft sleeve 4 is fixedly mounted in the large footpath section of guide 1 centre hole lower end, with front fork tube 2 bearing fit while of this Lower shaft sleeve 4.Step surface between Lower shaft sleeve 4 upper surface and guide 1 centre hole bottom path section and lower end large footpath section is close to, the lower surface of this axle sleeve 4 and packing ring 5 near.Packing ring 5 is arranged in the large footpath section of described guide 1 centre hole bottom from top to bottom successively with oil sealing 6 and collar 7, and simultaneously with front fork tube 2 bearing fit, and collar 7 is stuck in the annular mounting groove of this large footpath section.
The foregoing is only preferred embodiment of the present utility model; it is not restriction with the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
