Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, and to make those skilled in the art better can understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.

As depicted in figs. 1 and 2, a kind of single armed shock attenuation unit of the utility model, comprise inner support tube 1, inner support tube 1 periphery is set with damper spring 2, first cushion rubber bumper 31 and outer support pipe 4 from bottom to up successively; Damper spring 2 lower end be provided with the first spring stop piece 51; The second spring stop piece 52 is provided with between damper spring 2 and the first cushion rubber bumper 31; Outer support pipe 4 lower end edge radial direction extends into stop plane 41 and connects with the first cushion rubber bumper 31 upper end; Outer support pipe 4 upper end is provided with back-up ring 53.

Compared to current widely used pair of fork damper, the utility model adopts a damping assembly to realize effectiveness in vibration suppression, saves material and cost of labor.

For making inside and outside support tube jointly turn to, outer support pipe 4 of the present utility model is provided with multipair ball grooves 61 with relative vertically between inner support tube 1, is provided with the ball row of multiple ball 6 composition in ball grooves 61.Preferably, ball grooves 61 have three right.Ball grooves 61 is the groove that inner support tube outer wall and outer support inside pipe wall have, ball 6 is evenly placed in groove respectively, when such rotation inner support tube, due to the effect of power, outer support pipe 4 can rotate along with the rotation of inner support tube 1, inside and outside support tube entirety is rotated simultaneously, and the torsion that can not produce because of partial rotational has influence on the running of damping part.In addition, inside and outside support tube can produce axial relative motion when damper spring 2 elastic deformation, due to ball grooves system axial groove, makes motion more convenient.More preferably in embodiment, upper and lower two ends can be arranged be provided with wear-resisting copper bar 7 by the ball between inside and outside support tube.If need not wear-resisting copper bar, so ball will produce constant collision, worn out ball with two ends irony port, cause stuck.And copper parts itself have stronger resistance to abrasion, be placed in two ends and ball can be made directly directly not contact with irony port, and copper itself also there is certain lubricating effect.Connection based on the utility model and other parts is considered, can be arranged with outside thread 42 outside support tube upper end outside.

In another embodiment, back-up ring 53 can be provided with two, is provided with the second cushion rubber bumper 32 between two back-up rings.For making damper spring 2 in external world's isolation, damper spring periphery of the present utility model is also provided with scalable dust protecting cap 8, and scalable dust protecting cap 8 lower end is placed in the inner support tube 1 under the first spring stop piece 51, and scalable dust protecting cap 8 upper end is placed on outer support pipe 4 bottom.

Outer support Guan Keyu riding cycle of the present utility model turn to bowl group or bearing class rotary components heavy keying fit, ball vertically ball grooves does straight reciprocating motion and participates in circumference torque transmission.It is important to note that the gap in the middle of inside and outside support tube should be suitably a little bit smaller, such ball can corresponding reduction to the area of contact galling of ball grooves.The utility model can be general for riding cycles such as mountain bike, variable speed bicycle and motor bikes.
