Problems solved by technology
When the vehicle is parked on a relatively complicated road section, such as: tunnels, platforms, track water, etc., the operator cannot get off the vehicle to operate the relief handle, causing the vehicle to have to run with brakes, which will damage the wheels or brake discs, brake shoes or brake pads and other components, shorten the service life, and even cause serious accidents such as brake failure

The embodiment of the invention provides a railway vehicle parking brake relieving device and a railway vehicle, and the relieving device comprises an operation part which is used for being arranged in a carriage; the operating part comprises a shell, an operating handle and a force transmission assembly; the force transmission assembly is arranged in the shell, one end of the operating handle is inserted into the shell and connected with the force transmission assembly, and the operating handle moves relative to the shell and is used for driving the power transmission assembly to generate linear motion; an on-vehicle stay wire compnent is used for being arranged in a carriage, one end of the on-vehicle stay wire component is connected with the force transmission assembly, and the other end of the on-vehicle stay wire component penetrates through the bottom of the carriage; an under-vehicle stay wire component is used for being arranged on a bogie; one end of the under-vehicle stay wire component is connected with the on-vehicle stay wire component, and the other end is connected with the brake cylinder; the under-vehicle braking component, the on-vehicle braking component and the force transmission assembly move synchronously so as to relieve the braking force of the braking cylinder. According to the railway vehicle parking brake relieving device and the railway vehicle provided by the embodiment of the invention, the parking brake can be relieved on the vehicle.
Description
technical field [0001] The present application relates to rail vehicle braking technology, in particular to a rail vehicle parking brake release device and a rail vehicle. Background technique [0002] Rail vehicles are an important transportation link connecting cities, and have gradually become the main means of transportation in cities. Rail vehicles are also the main carrier for cargo transportation. A rail vehicle generally includes: at least one carriage, and a bogie is arranged under the carriage, and the bogie has the functions of carrying the carriage and providing travel. A brake cylinder is arranged on the bogie to brake the wheels in the braking state. Parking brake is a kind of brake applied when the rail vehicle is parked temporarily or for a long time to prevent the vehicle from slipping during parking. [0003] In the traditional technology, the parking brake operating device includes: a button for automatically applying and releasing the parking brake and ...
