Description

Bicycle caliper

The present invention relates to a bicycle caliper.

In recent years, cycling has become popular, and in addition to developing better transmission systems, the industry has also focused on developing brake systems. The brake system is related to the personal safety of the rider. Common brakes include slings, C-clips, V-clips and calipers. Among them, the calipers are often used on bicycles with higher performance, and the calipers can be divided into hydraulic and mechanical types. Because the hydraulic type is usually more expensive, it is accepted by beginners who are more easily introduced by mechanical type, such as TWI505964. This is the case with the bicycle calipers disclosed.

In the conventional caliper structure, the components are driven to be driven to move the sheet relative to the caliper body to clamp against the disk for braking purposes. However, as the use time and the number of brakes increase, the mechanical structure often causes deformation of some components due to stress concentration and collision, which will lead to many adverse effects such as poor structural force transmission, which is currently a problem to be solved.

Therefore, it is necessary to provide a novel and progressive bicycle caliper to solve the above problems.

The main object of the present invention is to provide a bicycle caliper that provides a better driving mode. The driving member rotates with the shaft member as an axis, and drives the sliding member toward the disc through the rotation of the shaft member to achieve the purpose of braking. By means of the rotary fit, there is less chance of jamming between the components, which can prevent the components from being deformed due to the stuck and sustained force; and the slider can be rotated in a better manner. force.

To achieve the above object, the present invention provides a bicycle caliper comprising a body and at least one brake unit. The body is provided with a hollow portion into which a disc is inserted. Each of the brake units includes an actuating member, a shaft member, a sliding member and at least one driving mechanism.

The sliding member 23 is slidably disposed on the shaft member 22 , and the at least one driving mechanism 3 is disposed between the body 1 and the sliding member 23 . When the actuating member 21 is driven by the outside, the at least one driving mechanism 3 pushes against the body 1 and the sliding member 23, thereby forcing the sliding member 23 to move toward the hollow portion 14.

Each of the brake units 2 is further provided with a brake member 36 for abutting against the disk D. The brake member 36 is movably disposed on the hollow portion 14. The slider member 23 is interposed between the brake member 36 and the actuating member. Between 21 . Wherein, when the actuating member 21 is driven by the outside, the sliding member 23 pushes against the braking member 36 against the disc D to achieve the purpose of braking the disc D. Preferably, a plurality of heat dissipation fins 361 are disposed on the brake member 36 to increase the efficiency of heat dissipation, and ensure that the disk D and each of the brake members 36 are maintained at a proper operating temperature.

The actuating surface 233 is rotated relative to the body 1 when the actuating member 21 is driven by the outside. The portion of the rolling member 32 is directed by the trough portion 312. The peak portion 311 moves, thereby forcing the slider 23 to move toward the hollow portion 14, and the brake member 36 abuts against the disk D (see Fig. 6). It should be particularly noted that the at least one driving mechanism 3 is not necessarily limited to being respectively disposed on the sliding member 23 and the body 1 as long as it is located between the sliding member 23 and the body 1 and can drive the sliding member 23 The mobile is the range of applications that you want to protect.
