Abstract

The invention provides an electro-mechanical braking actuator of a rail vehicle. The electro-mechanical braking actuator of the rail vehicle comprises a motor. One end of the motor is connected with agear transmission system. One end of the gear transmission system is connected with a lead screw transmission device. One end, in the advancing direction, of the lead screw transmission device is fixedly connected with a brake pad push plate. The other end, in the advancing direction, of the lead screw transmission device is provided with a force sensor. The electro-mechanical braking actuator ofthe rail vehicle effectively achieves accurate control of the brake force, achieves the braking skid resistance function and the park braking function on the rail vehicle, and the problems of the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle brake systems, and in particular relates to an electromechanical brake actuator device for rail vehicles. Background technique [0002] The electromechanical braking system technology uses the motor to drive the mechanism to realize the braking action, and directly converts the electrical signal into the braking force output through the motor and the deceleration mechanism. Compared with the traditional braking system, the braking pipeline in the entire system is omitted. It has the advantages of simple structure, small volume, fast response speed and high control precision. It has been extensively researched in the fields of aviation and automobiles, and is the main technology of the new generation of rail vehicle braking systems. [0003] The electromechanical braking system of rail vehicles includes components such as a control system and a brake caliper, wherein the electromechanical bra...
