The invention relates to the field of rail vehicle central traction devices, and provides a single-pull-rod central traction device for a bogie, the bogie and a rail vehicle. The traction device comprises a traction pin seat, vertical stops and a traction pull rod. The traction pin seat comprises a vehicle body sleeper beam connecting seat, a pair of transverse stop baffles, a traction pull rod mounting seat, and a pair of vertical stop mounting seats, wherein the pair of transverse stop baffles are oppositely arranged on the two transverse sides of the vehicle body sleeper beam connecting seat, and a transverse shock absorber mounting seat is formed at the bottom of one transverse stop baffle; the traction pull rod mounting seat comprises a pair of traction pull rod mounting supports which are arranged at intervals along one longitudinal side of the vehicle body sleeper beam connecting seat; and each of the pair of vertical stop mounting seats is formed at the bottom of each tractionpull rod mounting support. The pair of vertical stops are fixedly connected to the pair of vertical stop mounting seats respectively, and the stop ends face the longitudinal direction of the vehicle body sleeper beam connecting seat and are opposite in direction; and one traction pull rod is connected to the pair of traction pull rod mounting supports and the bogie frame. The single-pull-rod traction device can solve the problem that an existing single-pull-rod traction device is large in occupied space and difficult to install in a bogie.
Description
technical field [0001] The invention relates to the technical field of a central traction device for a rail vehicle, in particular to a single tie rod central traction device for a bogie, a bogie and a rail vehicle. Background technique [0002] There are many kinds of central traction devices currently applied to rail vehicle bogies, which are generally divided into Z-shaped double-rod traction devices and single-rod traction devices. The Z-shaped double-tie rod traction device includes a traction pin seat and a draw beam. One end of the double draw rod is connected to the draw beam, and the other end is connected to the frame. This kind of traction device has a relatively complicated structure and requires a large space. In the single-tie-rod traction device, the traction beam is generally canceled, and one end of the traction rod is directly connected to the traction pin seat, and the other end is connected to the frame. The current single tie rod traction device is gene...
