Abstract

The embodiment of the invention provides a relieving cock device of a railway vehicle and an air cylinder module. The relieving cock device comprises a brake cutting cock with an electrified contact, an on-vehicle relieving mechanism, and a transmission mechanism, wherein the brake cutting cock comprises a cock body and an electrified switch box, and the cock body is installed on a main air pipeline; the on-vehicle relieving mechanism is fixed with the vehicle body; the transmission mechanism comprises an upper transmission disc, a lower transmission disc and a flexible transmission belt; the upper driving disc is coaxial with an on-vehicle relieving mechanism, the cock body, the lower driving disc and the electrified switch box are sequentially coaxial from bottom to top, and the driving belt is tensioned on the peripheral surfaces of the on-vehicle driving disc and the lower driving disc, so that when the on-vehicle relieving mechanism rotates, a shaft of the cock body and a shaft of the electrified switch box are driven to rotate through transmission of the upper driving disc, the driving belt and the lower driving disc; the electrified switch box is used for transmitting a rotation signal of the electrified switch box to a control system of the railway vehicle. The air cylinder module comprises the relieving cock device. According to the embodiment of the invention, the technical problem that the requirement of the relieving cock device of the railway vehicle on the mounting environment is high is solved.

Description

technical field [0001] The present application relates to the technical field of rail vehicles, and in particular, relates to a relief plug device and an air cylinder module of a rail vehicle. Background technique [0002] With the rapid development of urban rail transit, the demand for urban rail transit vehicles is increasing, and vehicle design not only needs to meet various complex performance requirements of vehicles. like figure 1 As shown, the air cylinder module of the rail vehicle includes a mounting hanger 10, three air cylinders (main air cylinder, empty spring air cylinder and brake air cylinder 21) and a relief plug device. The relief cock device includes a brake removal cock 31 and a mechanical relief device 32 arranged on the main air duct; wherein, the under-vehicle relief mechanism is used to remove the brake when the bogie brake fails. It is usually required to be able to operate the under-vehicle mitigation mechanism both on and off the vehicle. In orde...
