Abstract

The invention relates to a brake device and an electrically driven brake cylinder. The electrically-driven brake cylinder comprises an installation cylinder body, a driving part, a bearing assembly, a threaded rod, a threaded transmission part and a telescopic part, the installation cylinder body is used for being installed and matched with one brake rod of a brake device, the installation cylinder body is provided with an assembly cavity, and the bearing assembly, the threaded rod and the threaded transmission part are all located in the assembly cavity; the output end of the driving part is inserted into the assembling cavity and is in installation fit with one end of the threaded rod, the threaded rod is sleeved with the bearing assembly, the bearing assembly is used for being in rotating fit with the threaded rod, and the threaded transmission part is in transmission fit with the threaded rod; one end of the telescopic piece abuts against the threaded transmission piece in a transmission mode, and the other end of the telescopic piece stretches out of the assembly cavity and is used for being installed and matched with the other brake rod of the brake device.

Description

technical field [0001] The invention relates to the technical field of railway wagons, in particular to a brake device and an electric drive brake cylinder. Background technique [0002] When the railway freight car is braking, the brake cylinder applies a braking force to the brake rod, thereby driving the brake shoe to collide with the wheel to achieve braking. The traditional brake cylinder drives the screw rod, telescopic rod and other components in turn through the drive motor for transmission. However, the traditional brake cylinder has a poor braking force output effect due to its own structural limitations when applying the braking force. Contents of the invention [0003] Based on this, it is necessary to provide a braking device and an electrically driven brake cylinder to solve the problem of poor braking force output effect of the transmission brake cylinder. [0004] An electric drive brake cylinder. The electric drive brake cylinder includes: a mounting cyl...
