Problems solved by technology

However, disc brakes that rely on cables to pull the mechanical principle may lose [braking] force due to various factors such as the length and elasticity of the cable itself, and the friction of the casing.

Abstract

The invention discloses a brake crank, which comprises a pressing plate, a spring, a rivet, a handle, a buckle, a hollow rivet and a left bracket, wherein the spring is arranged between the lower part of the pressing plate and an accommodating cavity of the handle; a slot is formed on the buckle, and the buckle penetrates through the slot and is fixed on the handle through the rivet; a groove is formed in front of the left bracket and is engaged with a fastener at the front end of the pressing plate; the left bracket comprises a bracket and a main body; round holes are formed on two sides of the bracket and the main body and are engaged with a nut through a screw; and a mechanical power-off connecting wire resistor is arranged in the middle of the left bracket. The brake crank is suitable for bicycles and electric vehicles and has good brake effect, good handfeel and sensitivity; and moreover, the brake crank is smooth and labor-saving in manual labor relative to a pull wire disc brake, and adverse slope of the vehicle can be well prevented.

Description

technical field [0001] The invention relates to a brake handle, in particular to a brake handle suitable for automatic vehicles or electric vehicles. Background technique [0002] With the development of technology, more and more designs of disc brakes, as well as materials, have begun to reduce weight. Therefore, disc brakes are designed to be lightweight, high-sensitivity, and relatively easy to adjust. An official data once showed that the weight difference between the old Shimano950v brake system and the latest Shimano960 disc brake system does not exceed 100g, so this is enough to prove that with the current technological development, the manufacturing of disc brakes has been reduced. Lightweight technological content has been greatly improved. But, is it really necessary to use disc brakes? [0003] As far as the current level of use is concerned, I feel that using disc brakes is not the first choice. It is not a matter of money investment, but the degree of use and...
