Electronic mechanical and hydraulic two-purpose brake

Abstract

The invention relates to an electronic mechanical and hydraulic two-purpose brake, relating to the technical field of brake devices in automobile safety systems. The electronic mechanical and hydraulic two-purpose brake can be connected in parallel with an electronic mechanical brake system and a hydraulic brake system for use, and can be used independently in one mode. A central hole is arranged at the end surface of a hydraulic cylinder and brake caliper assembly (10) of a traditional hydraulic brake system, and an electronic mechanical driving mechanism which directly pushes a piston (9) to work is additionally arranged. The electronic mechanical and hydraulic two-purpose brake comprises a bearing seat (4) and a moment input shaft (1), wherein the moment input shaft (1) is installed in the bearing seat (4) through a thrust bearing (2); the moment input shaft (1) pushes a thrust rod (8) with a wedge-shaped end surface through a force transfer steel ball (3) with an embedded end surface; the thrust rod (8) is installed in the central hole at the end surface of the hydraulic cylinder and brake caliper assembly (10) through a key (5) and contacted with the piston (9); and the bearing seat (4) is fixedly connected with the hydraulic cylinder and brake caliper assembly (10). The brake has the advantages of simple structure, high respond speed and high reliability.

Description

Technical field [0001] The invention relates to a braking device in an automobile safety system, in particular to an electromechanical and hydraulic dual-purpose brake suitable for fast response speed and high reliability. Background technique [0002] Reliable braking system is the safety guarantee for car driving. The traditional hydraulic brake system adopts dual-circuit brake fluid measures to greatly ensure the reliability of the automobile brake system. In addition, the hydraulic brake system has simple structure and stable performance, and is widely used in various automobiles. But the hydraulic brake system adjusts the pressure through the brake master cylinder, and the torque response speed is slow, and it cannot meet the braking performance requirements under emergency conditions (World Automobile 2003.1, 27-28). Due to the slow braking response speed, high-speed rear-end collisions may occur, and car rollover accidents may occur during high-speed sharp turns. Theref...
