Description

Bicycle adjustable preload shock absorber

The new model relates to the technical field of bicycles, especially the technical category of its adjustable preload shock absorber.

An adjustable shock absorber traditionally used on bicycles. For example, a front fork system includes a strut tube, a slider tube that interacts with it, and an elastic damping between the strut tube and the slider tube The damping system of the mechanism utilizes an adjusting bolt set between the slide tube and the damping system to provide adjustment of the damping coefficient or damping stroke amount of the damping system, and to change the damping action amount of the adjustable damping device JP2003307245A patent discloses such a mechanism.

In addition, an elastic bearing seat is additionally provided between the pillar tube and the damping system, and the elastic bearing seat can contact the bottom dead center position of the damping system when the damping system descends, thereby absorbing the impact between the damping system and the pillar tube. Impact maintains the operational stability of the shock absorber in the shock-absorbing stroke, which is disclosed in patents such as CN2727037Y and TWI391580B.

However, the conventional adjustable shock absorber disclosed above, when the adjusting bolt for adjusting the damping coefficient of the damping system is pressed against the damping system, it may compress to the elastic bearing first, causing the damping system to be unadjusted. The shock absorption function of the elastic bearing is lost. Therefore, the conventional adjustable shock absorber really needs to be improved.

For this reason, in view of the problems of the conventional adjustable shock absorber, the main purpose of the creator of this new model is to provide a bicycle adjustable preload that does not lose the shock absorption function of the elastic bearing. The shock absorber; the secondary purpose of this model is to provide a bicycle adjustable preload shock absorber that is convenient to adjust.

In order to achieve the above purpose, the present invention uses the following technical means.

Regarding an adjustable preload shock absorber for bicycles, it includes: a telescopic tube body with a pillar tube and a slider tube that interacts with the pillar tube; a damping system is arranged between the pillar tube and the pillar tube A pre-compression adjusting device is mechanically coupled to the slide tube to compress the damping system by axial displacement relative to the slide tube to adjust the damping coefficient or damping stroke of the damping system; a The elastic bearing is arranged on the pillar tube or the sliding member tube to receive the damping system to absorb the impact of the damping system or the sliding member tube on the pillar tube, and the elastic bearing is set to adjust the pre-compression adjusting device When the damping coefficient or the damping stroke of the damping system, the elastic bearing does not produce compression or produce slight compression.

In the bicycle adjustable preload shock absorber, the preload adjustment device further includes an adjustment bolt and an adjustment ring, and the adjustment bolt is set as a bolt shaft, and the adjustment ring is provided with a bolt groove inner hole, And the inner hole of the bolt groove is sleeved on the bolt shaft, that is, the inner hole of the bolt groove of the adjusting ring integrally forms a plurality of wedges, and the plurality of wedges are inserted into the grooves of the bolt shaft; The bolt shaft is provided with an external thread and is screwed to an internal screw hole provided in the sliding member tube.

In the shock absorber with adjustable precompression for bicycles, the elastic bearing seat has an elastic coefficient that does not produce a compression effect or only produces a slight compression when the adjusting bolt adjusts the damping system.

In the bicycle adjustable pre-compression shock absorber, the elastic bearing has a compressible volume that does not produce a compression effect or only produces a slight compression amount when the adjusting bolt adjusts the damping system.

In the bicycle adjustable pre-compression shock absorber, the ratio of compression between the elastic bearing and the adjusting bolt when adjusting the damping system is less than 1:5, and particularly less than 1:10, and is particularly preferred Land is less than 1:20.

In the bicycle adjustable preload shock-absorbing device, a plurality of radial holes and grooves are arranged around the adjusting ring, and a radial through hole is arranged on the slide tube corresponding to the plurality of radial holes and grooves.

The bicycle adjustable preload shock absorber is provided and can be installed in the front fork frame, seat tube or rear fork frame of the bicycle.

Through the above technical means, the present invention can achieve the following effects:

1. When the damping system is pressed against (ie pre-compressed) by the adjusting bolt for adjusting the damping coefficient of the damping system, the new model does not compress to the elastic bearing first, and then maintains the existing absorption of the elastic bearing Impact function.

2. The new model can be inserted into the radial hole groove of the adjusting ring by the adjusting tool extending through the through hole of the sliding piece tube, providing convenient rotation of the adjusting ring to actuate the adjusting bolt to push down (Ie pre-compression) the damping system.

Please refer to Figures 1 to 4, this new model relates to a bicycle adjustable preload shock absorber A, which can be installed in the front fork frame, seat tube or rear fork frame of the bicycle. Seatpost as The implementation description mainly includes: a telescopic tube body 1, a damping system 2, a pre-compression adjusting device 3 and an elastic bearing 4.

The telescopic tube body 1 is provided with a pillar tube 11 and a sliding member tube 12 that interacts with the pillar tube 11. In other words, the outer diameter of the sliding member tube 12 is smaller than the pillar tube 11, so the sliding member The pipe 12 can move relatively to the pillar pipe 11, and an oil seal 13 is usually provided at the entrance of the pillar pipe 11.

The damping system 2 is arranged between the strut tube 11 and the slide tube 12, so the damping system 2 provides the telescopic tube body 1 with a cushioning and shock-absorbing effect; usually the damping system 2 can distinguish a cylinder The body 21 and the actuating rod 22, and the damping system 2 can be installed in such a way that the actuating rod 22 faces upward (Figure 4), or the actuating rod 22 faces downward (Figure 6).

The pre-compression adjusting device 3, as shown in FIGS. 2 to 5, is mechanically coupled to the slide tube to axially shift relative to the slide tube 12 to compress the damping system 2 to adjust the damping system Further, the preload adjusting device 3 further includes an adjusting bolt 31 and an adjusting ring 32, and the adjusting bolt 31 is set as a bolt shaft 310, and the adjusting ring 32 is provided with a bolt groove Hole 320, and the one bolt groove inner hole 320 is sleeved on the bolt shaft 310. In other words, the bolt groove inner hole 320 integrally forms a plurality of wedges 322, and the plurality of wedges 322 are inserted into the bolt shaft 310 In addition, the adjusting ring 32 has a number of radial holes 321 around it, and the slider tube 12 corresponding to the several radial holes 321 is provided with a radial through hole 121.
