Description
Technical field
The utility model belongs to motorcycle field, particularly relates to the recovery adjusting mechanism on a kind of damper.
Background technique
Damper is a kind of vitals on motorcycle, and as shown in Figure 1, existing damper comprises clutch release slave cylinder 1, piston rod 3, and wherein the lower end of clutch release slave cylinder 1 is coaxially fixed with an anti-gland 2; Described piston rod 3 is solid hopkinson bar, the upper end of this piston rod 3 is coaxially installed with piston 4 and valve block 5, wherein piston 4 is clamped between the valve block 5 of both sides, and motive sealing between the endoporus of the periphery of piston 4 and described clutch release slave cylinder 1, and shock absorber fluid is marked with in the clutch release slave cylinder 1 of piston 4 both sides.In addition, be threaded in the lower end of piston rod 3 lower contact 8.It should be noted that, during work, shock absorber fluid can act on valve block 5, thus stops piston rod 3 to move up.Meanwhile, have the valve block 5 of shock absorber fluid from side of minute quantity, flow through piston 4, finally flow to the valve block 5 of opposite side.
The defect of existing damper is: because the shock absorber fluid only having minute quantity during work flows between the chamber of piston 4 both sides, so just cause the recuperability of damper substantially non-adjustable, user independently can not adjust recuperability according to the degree of jolting on road surface, thus causes comfortable feel poor.
Model utility content
Technical problem to be solved in the utility model is to provide the adjusting mechanism of the recovery on a kind of damper, and this mechanism can adjust recuperability.
The technical solution of the utility model is as follows: the recovery adjusting mechanism on a kind of damper, comprises clutch release slave cylinder (1) and piston rod (3), and wherein clutch release slave cylinder (1) lower end is coaxially fixed with an anti-gland (2); Described piston rod (3) upper end is coaxially installed with piston (4) and valve block (5), wherein piston (4) is clamped between the valve block (5) of both sides, motive sealing between the periphery of this piston and the endoporus of described clutch release slave cylinder (1), thus the inner chamber of clutch release slave cylinder (1) is divided into upper and lower two chambers, be all marked with shock absorber fluid in these two chambers; The lower end of described piston rod (3) has been threaded a lower contact (8), it is characterized in that: described piston rod (3) is hollow stem, be equipped with a valve rod (9) in the center hole of this piston rod, this root valve rod and piston rod (3) are slidably matched; The taper-face contact of described valve rod (9) lower end and cone screw (10), the shaft axis of this cone screw is vertical with the shaft axis of cone screw (10), and cone screw is threaded in described lower contact (8); Described valve rod (9) upper end is big end down conus portion, described piston rod (3) center hole top is to having a cone boss (3a) by conus portion, and the radial oil-through hole (3b) that a diameter is 1-3mm is had at this cone boss place, this radial oil-through hole is by the upper and lower chamber of described clutch release slave cylinder (1); The upper end of described piston rod (3) center hole is coaxially fixed with a valve stem casing (11), the center hole of this valve stem casing is big end down two-part shoulder hole, the large footpath section diameter of this center hole is greater than the diameter of described cone boss (3a) upper end, form an annular region (Q) between these two sections, this annular region can be closed gradually when described valve rod (9) moves up.
Compared with conventional construction, piston rod (3) is adjusted to hollow stem by solid hopkinson bar by the utility model, and in center hole, wear a valve rod (9), and moving up and down of this valve rod is regulated by cone screw (10); Meanwhile, cone boss (3a), radial oil-through hole (3b), valve stem casing (11) and annular region (Q) are also set up, the utility model is so just made to add the passage of a shock absorber fluid, that is: be communicated with upper and lower two chambers of clutch release slave cylinder (1) with the center hole of valve stem casing (11) through radial oil-through hole (3b), and the mistake oil mass of this passage is larger.When the motorcycle that this damper is housed is in vehicle stop state, user can tighten or loose cone screw, thus makes the downward or upper movement of valve rod.When valve rod moves up, this valve rod can closed ring region gradually, thus reduces recuperability.Otherwise, when valve rod moves down, this valve rod can open annular region gradually, thus a large amount of shock absorber fluids can be allowed to flow between the center hole of radial oil-through hole (3b), valve stem casing (11) and upper and lower two chambers of clutch release slave cylinder (1), and then increase recuperability.
Adopt above technological scheme, mechanism can adjust the recuperability of damper, it is simple, convenient to regulate, thus user can be made independently to adjust recuperability according to road bump situation, and then adjust travelling comfort according to the situation of user oneself, and the utility model structure is simple, easy to implement, improve the usability of damper well.
As preferably, described cone screw (10) outer end is installed with o shape circle (12) sealed, and so just can reach object that is dust-proof, sand prevention.
Beneficial effect: mechanism can adjust the recuperability of damper, it is simple, convenient to regulate, thus user can be made independently to adjust recuperability according to road bump situation, and then adjust travelling comfort according to the situation of user oneself, and the utility model structure is simple, easy to implement, improve the usability of damper well.
