Mountain bicycle

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...

AI Technical Summary

Problems solved by technology

Independent front frame design: a similar design is reflected in GT's ID floating bottom bracket design, and its advantages will not be repeated, but GT does not use a high-pivot design, as well as a coaxial design of the main link, lower link, and axle. Through, lower link, coaxial design, the design of the brake mounting seat on the lower link cannot reflect the advantages of this patented design

[0004] Mountain bikes with rear suspension need to face problems such as brake interference, pedal feedback, pedaling efficiency, anti-sinking, geometric changes caused by rear shock action, rigidity, etc. during design, and manufacturers need to make compromises, thus limiting performance
