Abstract

The invention discloses a mountain bicycle, which has a rear wheel structure and a front wheel structure. The mountain bicycle also has a rear tripod, a front tripod, a shock absorber, a connecting rod group, an eccentric rotating shaft, an auxiliary shaft, an auxiliary rod and an extension rod. The mountain bike has a rear tripod, a front tripod, a shock absorber, a connecting rod group, an eccentric shaft, an auxiliary shaft, an auxiliary rod and an extension rod. The mountain bicycle of the invention improves the pedaling efficiency when pedaling. It is easier to absorb shock when the obstacle is passed, and the change of geometry leads to the change of compression ratio, and the post-shock absorber is easier to be compressed, which improves the shock absorbing ability. When braking, the structural changes in the same obstacle, so that the shock absorber is easier to be compressed to slow down the phenomenon of shock rigidity.

Description

technical field

[0001] The invention relates to the field of mountain bikes and the like, in particular to a mountain bike. Background technique

[0002] Mountain bikes are bicycles specially designed for cross-country (hills, trails, wilderness and sandy gravel roads, etc.).

[0003] Some existing mountain bikes have a high pivot design and an independent front frame design. The mountain bike with a high pivot design is different from other mountain bikes. Rather, the design of the main pivot point is obviously higher than that of the crankset) and similar design is reflected in the high position pivot (HPP) structure of commencal, so I won’t repeat it here. However, Commencal or other high-rotation point designs make the chain length change too much due to the action of the rear shock absorber, so they install a guide wheel at the hinge of the rear suspension and the front frame to bypass the extended chain. The design undoubtedly adds a lot of weight, and the high-pivot...

Examples

Embodiment

[0024] Example: such as figure 1 As shown, a mountain bike has a rear wheel structure 1 and a front wheel structure 2.

[0025] In this embodiment, the rear wheel structure 1 is a commonly used structure of an existing high-pivot design mountain bike, which specifically includes a rear wheel 11 , a rear wheel shaft 12 , and a rear wheel frame. The same front wheel structure 2 includes a front wheel 21, a front wheel shaft 22, a front wheel frame 23 and the like. These structures are not further improved in the present invention.

[0026] Such as figure 2 As shown, the design points provided by the present embodiment are that the mountain bike also has a rear tripod 3, a front tripod 4, a shock absorber 5, a connecting rod group 6, an eccentric shaft 7, an auxiliary shaft 8, an auxiliary rod 9, Extension rod 10.

[0027] The rear wheel structure is assembled on the rear portion of the rear tripod 3; the front wheel structure is assembled on the front portion of the front t...
