Abstract

The embodiment of the invention provides a yoke end assembly, a transmission module, an electromechanical braking device, a braking clamp unit and a rail vehicle and relates to the technical field ofbraking. The electromechanical braking device adjusts the position of a power-losing locking mechanism, the electromechanical braking device is matched with a braking yoke to form a new yoke end assembly, so the whole electromechanical braking device is more reasonable in structure and function layout and more balanced in mass distribution, the braking force outputted by the electromechanical braking device can be accurately controlled, operation is more stable and reliable, moreover, assembly, disassembly and fault detection are further facilitated. Correspondingly, a braking clamp unit adopting the electromechanical braking device and a rail vehicle are more stable and reliable during running.

Description

technical field [0001] The invention relates to the technical field of braking, in particular to a yoke end assembly, a transmission module, an electromechanical braking device, a brake caliper unit and a rail vehicle. Background technique [0002] In the field of vehicle braking technology, especially in the field of rail transit braking technology, the braking system has mainly experienced through brakes, automatic brakes, through automatic brakes, electro-pneumatic brakes, computer-controlled through-electric-pneumatic Stages of development of braking systems. With the development of science and technology, electromechanical braking devices have gradually appeared on the market. The electromechanical brake device uses electric energy to directly drive the brake pads to rub against the brake disc (wheel tread), and then converts the kinetic energy of the vehicle into heat energy to produce a braking effect. [0003] However, the mass distribution of the existing electrom...
