Problems solved by technology

This hammering effect may produce noise and / or shock to the rider, which may lead the rider to believe that the brake drum has broken or other brake failure, when in fact no such limitation occurs Brake failure due to limited braking force

Embodiment Construction

[0011] FIG. 1 is a side view of a bicycle 101 including a particular embodiment of a braking force control mechanism. The bicycle 101 includes a frame 102 including a front fork 98 , a handlebar 104 fixed to the front fork 98 , a drive unit 105 including a chain and pedals, and a front wheel 106 and a rear wheel 107 with spokes 99 . As shown in FIG. 2, the front hub 1 includes a hub axle 10, a hub shell 111 placed around the hub axle 10, and first hub shells 111 placed between the hub axle 10 and the hub shell 11 at both ends of the hub shell 11. Bearing 13 and second bearing 14. The externally threaded portion 10 a is formed on the outer surface of the hub axle 10 , and the hub axle 10 is fixed to the end of the front fork 98 using the nut 52 . The braking force limiting mechanism 15 is placed on one side (the left side in FIG. 2 ) of the hub shell 11 . When the roller braking mechanism 80 is mounted on the front hub 1 , a part of the excessive braking force input from the ...

Abstract

A bicycle hub comprises a hub shaft structured to be mounted to a bicycle frame , a hub shell rotatably supported relative to the hub shaft, a brake force receiving member rotatably supported relative to the hub shaft, a brake force limiting mechanism housed by the hub shell, and a brake contact member . The brake contact member includes a brake friction surface dimensioned to frictionally contact a brake force applying member . The brake force limiting mechanism communicates a brake force from the brake force receiving member to the hub shell and limits a maximum braking force communicated from the brake force receiving member to the hub shell. The brake contact member is securely mounted to the brake force receiving member without play.

Description

technical field [0001] The present invention relates to bicycles, and more particularly to bicycle hubs using braking mechanisms. Background technique [0002] A typical bicycle hub generally includes a hub axle, a cylindrical hub shell (housing) and bearings, wherein the hub axle is detachably and non-rotatably mounted on the bicycle fork (vehicle frame), and the hub shell wraps around The bearing is mounted on the hub axle, and the bearing rotatably supports the hub shell on the hub axle. Hub flanges are formed at opposite ends of the hub shell for mounting the hub shell on the spokes of the wheel. A brake mechanism device that controls the rotation of the hub shell relative to the hub axle may be mounted between the bicycle frame and the hub shell. In some bicycles, a braking force limiting mechanism including a friction clutch may be mounted inside the profile. The brake force limiting mechanism provides an anti-lock function for the hub by causing the friction clutch...
