Description
Technical field
The utility model relates to a kind of motorcycle part, particularly relates to the inverted front shock absorber on motorcycle.
Background technique
What be well known to those skilled in the art is, inverted front shock absorber is the vitals on motorcycle, as shown in Figure 1, 2, existing inverted front shock absorber comprises guide 1 and Upper shaft sleeve 5, wherein the upper end of guide 1 center hole is connected with a plug screw 2, coaxially be provided with a cushion pad 3 between the underpart of this plug screw 2 and the hole wall of guide 1 center hole, and the center hole of guide 1 is inserted on the top of front fork tube 4, the shaft axis of these two parts is on same straight line.The diameter of guide 1 center hole bottom is less than the diameter of its underpart, is formed with a step surface between these two sections.Upper shaft sleeve 5 and Lower shaft sleeve 6 is installed with vertically in the underpart of guide 1 center hole, separated by lining C between these two axle sleeves, and Upper shaft sleeve 5 is by the step surface axial limiting between guide 1 center hole bottom and underpart, and Lower shaft sleeve 6 is by packing ring 7, oil sealing 8 and collar 9 axial limiting, and packing ring 7, oil sealing 8 and collar 9 are arranged on the underpart of described guide 1 center hole from top to bottom successively.Meanwhile, Upper shaft sleeve 5 and Lower shaft sleeve 6 are slidably matched with the top of described front fork tube 2, and the lower end of guide 1 center hole is coaxially installed with a dust ring 10.
In the fabrication process, we find that existing structure exists following defect:
Because Upper shaft sleeve 5 and Lower shaft sleeve 6 are arranged on the underpart of guide 1 center hole, and Upper shaft sleeve 5 is by the step surface axial limiting between guide 1 center hole bottom and underpart, so just needs to have higher coaxality between the underpart of guide 1 center hole and guide 1.In order to ensure above-mentioned coaxality specially, manufacture cost will be increased in manufacture process and reduce work efficiency, if the coaxality between the underpart of guide 1 center hole and guide 1 cannot be guaranteed, will cause the shaft axis of the shaft axis 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 travelling comfort not good.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of inverted front shock absorber, front fork tube is moved up and down in process run smooth and easy.
The technical solution of the utility model is as follows: a kind of inverted front shock absorber, comprise guide (1), Upper shaft sleeve (5) and Lower shaft sleeve (6), wherein the upper end of guide (1) center hole is connected with a plug screw (2), a cushion pad (3) is coaxially provided with between the hole wall of the underpart of this plug screw and guide (1) center hole, and the center hole of guide (1) is inserted on the top of front fork tube (4), the shaft axis of these two parts is on same straight line, it is characterized in that: described Upper shaft sleeve (5) is coaxially solidly set on front fork tube (4) upper end, and be slidably matched with the center hole of described guide (1), described Lower shaft sleeve (6) is fixedly mounted in the large footpath section of guide (1) center hole lower end, and this Lower shaft sleeve is slidably matched with described front fork tube (4) simultaneously, step surface between described Lower shaft sleeve (6) upper-end surface and guide (1) center hole underpart path section and lower end large footpath section is close to, the lower end surface of this axle sleeve and packing ring (7) near, and packing ring (7) and oil sealing (8) and collar (9) are arranged in the large footpath section of described guide (1) center hole bottom from top to bottom successively, collar (9) is stuck in the annular mounting groove of this large footpath section, and the lower end of guide (1) center hole is coaxially installed with a dust ring (10).
Compared with conventional construction, improvements of the present utility model are: 1, the underpart of guide (1) is adjusted to path section, its lower end is adjusted to large footpath section, and install Lower shaft sleeve (6) in this large footpath section, and Lower shaft sleeve (6) and guide (1) are slidably matched; 2, by the position of Upper shaft sleeve (5) by original guide (1) being adjusted on present front fork tube (4), and Upper shaft sleeve (5) is slidably matched with guide (1) in the utility model; 3, owing to relative movement can be there is in this configuration between Upper shaft sleeve (5) and Lower shaft sleeve (6), so just no longer the lining in conventional construction is needed.
Adopt above technological scheme, the utility model is mainly through the mounting point of adjustment Upper shaft sleeve, not only reduce the difficulty of processing of guide 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 practicability.
For the ease of installing, the upper end of described front fork tube (4) has an annular groove, and described Upper shaft sleeve (5) is arranged in this annular groove.
Beneficial effect: the utility model is mainly through the mounting point of adjustment Upper shaft sleeve, not only reduce the difficulty of processing of guide 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 practicability.
