Description

Car calipers

The present invention relates to calipers, and more particularly to a caliper for a vehicle.

The braking system is related to the personal safety of the rider and is used in, for example, automobiles, bicycles, locomotives, and the like. Take bicycle as an example. Common brakes include suspension brake, C clamp, V clamp and caliper. Among them, calipers are often used on higher-performance bicycles, and calipers can be divided into hydraulic and mechanical types. Because hydraulic types are usually more expensive, mechanical types are easier for beginners, such as Taiwan. Such is the bicycle caliper disclosed in patent number TWI505964.

In the conventional caliper structure of this kind, each element is driven by the interlocking action of each element to move the piece relative to the caliper body and clamp the disc against it, so as to achieve the purpose of braking. When the vehicle speed is too fast (such as downhill acceleration), the deceleration also needs to be more agile. However, the calipers of the conventional technology mainly use a single-side single-piston push to hold the disc and clamp it against the disc. The area is small, and it is more difficult to push evenly to make the clips against the calipers, resulting in uneven force of the clips and unable to provide a better braking effect.

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

The main object of the present invention is to provide a caliper for a vehicle to simultaneously drive a plurality of axis moving mechanisms on the same side.

In order to achieve the above object, the present invention provides a caliper for a vehicle, comprising: a caliper body; a plurality of shaft moving mechanisms arranged axially movably on at least the same side of the caliper body; and a linkage mechanism connected to the plurality of shafts. At least two of the moving mechanism are in contact with each other, and the operation of the linkage mechanism drives the at least two-axis moving mechanism to move.
