Problems solved by technology

Drum brakes also have problems such as being greatly affected by water and heat, and the braking efficiency is obviously attenuated.
The disc brakes used in automobiles are limited by the size of the wheel hub and the braking torque is small, so it is difficult to meet the braking torque requirements of trucks; and compared with drum brakes, there are also disadvantages such as high cost

Embodiment Construction

[0032] figure 1 It is the principle diagram of the conical surface friction braking of the present invention. The brake pressure bearing member 1 is circular, rotates around its center line 2 and has a conical surface 4 on it. The brake pressure applying member 3 has a conical surface 4 matching the brake pressure receiving member 1, and the braking force F can be applied to the brake pressure receiving member 1. The brake pressure applying member 3 can be arranged separately or symmetrically arranged along the circumference of the brake pressure receiving member 1, as shown by the double-dot chain line in the figure. When the angle between the braking force F and the cone surface is α, the pressure N=F / sinα generated on the two cone surfaces is 1 / sinα times the braking force F. The two conical surfaces generate a friction force of Nμ (μ is the sliding friction coefficient) under the action of the pressure N, thereby generating a braking torque relative to the center line 2 to...

Abstract

The invention relates to a friction brake for industry and automobiles, which is structurally characterized in that a brake friction pair consists of a brake pressure stressing piece and a stressed piece, wherein the friction surfaces of the brake pressure stressing piece and the stressed piece adopt conical surfaces, and another mode relative to the existing drum brake that the cylindrical surface and the disk brake adopt the end surfaces to produce friction torque is adopted, and the conical surface friction brake belongs to the technical field of mechanical devices and transportation. As the conical surface friction brake has the characteristics of the realization of being automatically reinforcing and changing the included angles between the brake acting force and the conical surfaces, so as to adjust the size of the torque, and the like, the friction brake can improve the interchangeability of the brake parts, widen the friction material selecting range, save the energy sources, and increase the brake torque, as a result, the friction brake has wide application prospect in the industry and the automobile brakes.

Description

Technical field [0001] The invention relates to a friction type brake used in industrial and automobile braking. The friction pair used for braking is composed of a brake pressure applying member and a force receiving member. The friction surface adopts a conical surface, which is another way to use a cylindrical surface compared to the existing drum brake and an end surface friction for a disc brake. It belongs to the field of mechanical devices and transportation technology. Background technique [0002] The structure types of friction brakes include drum brakes and disc brakes. Drum brakes are divided into outer block type and inner shoe type. The friction surface of drum brake uses the inner or outer cylindrical surface of the brake drum; the friction surface of disc brake uses the end surface of the brake disc. According to different places of use, drum and disc brakes can be divided into industrial brakes and automobile brakes. [0003] As a general mechanical device, fric...
