Problems solved by technology

Due to the frequent braking of ten locomotives, the wear between the brake pads and the wheel tread or the brake disc will make the gap between the brake pads and the wheel tread or the brake disc larger and larger, resulting in a decrease in the braking force, resulting in the inability to operate the locomotive Braking will seriously affect the safety of locomotive operation
At present, the brake clearance adjustment device of the locomotive unit generally adopts a ratchet hook type clearance adjustment mechanism. The main disadvantages of this adjustment mechanism exposed during op

Example Embodiment

[0017] The present invention will be further described below in conjunction with the drawings and specific embodiments:

[0018] A brake gap adjustment device for locomotives and vehicles, comprising: brake shoe 2, and gap detection device 3, signal conditioning module 4, microcontroller 5, stepping motor 6, and electric actuator 7, characterized in that the gap detection device 3 Detect the change of the gap between the wheel tread 1 and the brake shoe 2, and transmit the gap value to the microcontroller 5 through the signal conditioning module 4. When the gap change meets a preset condition, the stepping motor 6 is triggered to drive The electric actuator 7 adjusts the gap between the wheel tread 1 and the brake shoe 2 to realize the gap control of the brake of the rolling stock.

[0019] The electric actuator 7 is used to drive the gap between the wheel tread 1 and the brake shoe 2 to the normal gap setting value: 5-8mm according to the stroke command issued by the microcontroll...

Abstract

The invention provides a gap adjusting device for a locomotive brake. The gap adjusting device comprises a wheel tread, a brake shoe, a gap detecting device, a signal conditioning module, a micro-controller, a stepping motor and an electric actuating mechanism. By means of the gap adjusting device, the distance between the brake shoe and the wheel tread, the distance between a braking lining and the wheel tread, the distance between the brake shoe and the wheel tread and the distance between the brake lining and the brake disc can be adjusted automatically and kept constant.

Description

technical field [0001] The invention relates to a rolling stock brake, in particular to a clearance adjustment device for a rolling stock. Background technique [0002] The locomotive unit brake is an important component of the locomotive's basic braking device. It applies the air braking force to the wheel tread or brake disc through the amplifying mechanism, brake shoe or brake pad to generate frictional braking torque, thereby exerting force on the locomotive. air brake. Due to the frequent braking of ten locomotives, the wear between the brake pads and the wheel tread or the brake disc will make the gap between the brake pads and the wheel tread or the brake disc larger and larger, resulting in a decrease in the braking force, resulting in the inability to operate the locomotive Braking will seriously affect the running safety of the locomotive. At present, the brake clearance adjustment device of the locomotive unit generally adopts a ratchet hook type clearance adjus...
