Problems solved by technology

A disadvantage of this type of suspension is that when the distance between the two bushings or the length of the bushing is too small, the fork cannot handle certain front / rear loads
This results in a binding to the fork
Another disadvantage of a suspension system in the head tube or steering tube is that the length of the tube may need to be increased to accommodate the suspension system
However, it is desirable to have a shorter steering tube

Embodiment Construction

[0015] 1 to 5 illustrate a bicycle front fork 10 having a suspension system 12 associated with a head tube (not shown) of a bicycle frame, according to one embodiment of the present invention. The suspension system 12 generally includes an inner tube 14 , an outer tube 16 , a shock absorbing mechanism 18 , a first bushing 20 , a second bushing 22 and a steering control mechanism 24 . Referring to FIG. 1 , the fork 10 includes a first leg 26 , a second leg 28 , a bellows 30 and an outer tube 16 mountable to the head tube, the bellows being disposed between the outer tube 16 and the legs 26 , 28 To seal and protect the suspension system 12 from foreign objects. An end 36 of the outer tube 16 is connected to a bellows 30 connected to the legs 26, 28 of the fork 10 (see FIG. 2 ). First leg 26 and second leg 28 are connected at their distal ends 32 by dropouts 34 to an axle (not shown). The first and second legs 26 , 28 and the inner tube 14 move axially or slidingly relative to ...

Abstract

A suspension system disposed in a bicycle fork. The suspension system includes inner and outer tubes, first and second bushings, a steering mechanism and a shock-absorbing mechanism. The first and second bushings are disposed between the inner and outer tubes to facilitate the sliding of the inner tube within the outer tube. The steering mechanism prevents relative rotation between the inner and outer tubes and is disposed between the first and second bushings. With this configuration, the ratio of the bushing length to the inner tube diameter is greater than 4, resulting in the suspension fork handling most lateral loads without binding.

Description

technical field [0001] The present invention relates to bicycle suspension systems, and more particularly to suspension systems provided in bicycle forks. Background technique [0002] Suspension systems, commonly used on handlebar vehicles such as bicycles and motorcycles, are designed to absorb shock and vibration experienced by the rider as the bicycle traverses bumps in the riding surface. The suspension system may be located in or near the fork, seat tube, head tube, and other frame locations of the bicycle. A suspension system in a head tube or steering tube may, for example, include an outer tube, an inner tube slidable in the outer tube, a damping mechanism, a steering control mechanism, and two bushings between the inner and outer tubes To facilitate the sliding movement between the inner tube and the outer tube. A disadvantage of this type of suspension is that when the distance between the two bushings or the bushing length is too small, the fork cannot cope wit...
