Problems solved by technology

[0002] With the development of transportation, the bicycle industry is changing with each passing day, and there are many new products. Bicycles have changed from a means of transportation in the past to a fashionable sports equipment today. People also put forward higher requirements for the performance of bicycles, such as multi-stage transmission. , large bearing capacity, good shock resistance, durable, especially good braking ability, the excellent performance of the bicycle has a lot to do with the structure of the front and rear hubs, the traditional front and rear hubs of the bicycle are mainly composed of It is composed of bead bowl, steel ball, shaft block, nut, and shaft. The main disadvantages are: the parts are loose, the whole is not firm after assembly, easy to damage, poor shock resistance, small bearing capacity, and poor braking performance, so it is urgent to improve

Abstract

The invention relates to a bicycle expansion brake hub assembly, which comprises a hub and a centre shaft, wherein the hub is composed of a rim and a disk chuck, and one end of the hub is provided with a brake component. The brake component is composed of an expansion block, a roller skeleton, an inner baffle plate, an outer cover plate, return springs, a torsion spring and brake tiles, and the brake tiles are uniformly distributed around the inner wall of the shell of the disk chuck. A notch slot is arranged in the roller skeleton, and rollers are arranged in the notch slot. The inner baffle plate and the outer cover plate are respectively sheathed on flat heads of two sides of a plummer block. The expansion block is hexagonal and is embedded in the inner cavity of the roller skeleton, and the outer side of the expansion block is fixedly connected with an end plate. A brake wrench is arranged on the end plate, and the outer cover plate is arranged at the outer side of the expansion block. The torsion spring is arranged between the end plate and the outer cover plate on the outer side of the expansion block, and each return spring is hooped in an arc-shaped groove of the excircle of each brake tile. The bicycle expansion brake hub assembly has the advantages of compact structure, firm and reliable whole, compression and vibration resistance, large bearing capacity and good brake performance, is not easily damaged, is durable in use, and can be used as a front hub or a rear hub.
