Structure for connecting hub with disc seat of bicycle

Abstract

The invention discloses a structure for connecting a hub with a disc seat of a bicycle. The structure comprises the hub and the disc seat. A retaining portion which is in the shape of a protruded ring, an outer thread which extends axially and of which the outer diameter is less than the retaining portion, and an axle are sequentially arranged at one end of the hub, the disc seat is in the shape of a C-shaped ring seat, a slot is arranged at the C-shaped opening, a lock catch thread lock is used for driving the slot to form a gap with different tightness at the C-shaped opening and further change the size of the inner diameter of the disc seat, an inner thread is connected with the outer thread, thus firmer thread connection is guaranteed and loosening is not easily caused, the connection way of one end face of the disc seat can be changed along with the six-hole type and the central locking tape of a braking disc, to allow the braking disc to be positioned at the disc seat and the hub, therefore the hub in the single type is applicable despite of different functions and types of the braking disc and a V-shaped caliper brake, and thus the high cost caused by manufacturing hubs in different types is lowered.

Description

technical field [0001] The invention relates to the technical field of bicycles as transportation equipment, in particular to a bicycle flower hub connection disc seat structure. Background technique [0002] According to the brake device of the bicycle, it can be roughly divided into V clamp brake and disc brake device. The disc brake device has different classifications because of the different types of brake discs. The brake disc can be selected as Six hole type, and center locking type. Due to the different brake discs, the components installed on the brake discs are also different. For example, I393652. The bicycle disc brake hub and transmission structure invention patent case, as well as the M327835 "Disc Adapter" Taiwan New Patent Case, and the M420480 "Bicycle Disc Brake Assembly" Taiwan New Patent Case, all show that the brake disc is made in Six perforations are equally divided around the center hole. This is a six-hole brake disc. In the Taiwan invention pate...

Problems solved by technology

[0003] The aforementioned hub is designed to match disc brakes, so the type of one end connecting the hub to the brake disc is different from the type of hub that matches the V-clip brake; the hub that matches the V-clip brake An external thread is formed at one end to engage the ratchet wheel and the flywheel. Therefore, to match different brake systems, it is necessary to replace the hub with different functional types. Therefore, it is necessary to stock and manufacture different hubs. There is a problem that it is difficult to use universally. Concerns about high costs of manufacturing and stocking flower hubs
