Abstract

The invention provides a positioning locking component, a beam crossing device and a rail wagon. The positioning lock component includes a guide pin, an elastic ring, and an elastic lock, wherein the guide pin is provided with a rod body and an end head which is arranged at one end of the rod body, the elastic ring with an axial deformation quantity is sleeved on the rod body, the size of the end head is bigger than the size of the rod body and also bigger than the inner diameter of the elastic ring, and the elastic lock with a radial deformation quantity is fixed on one end of the rod body away from the end head. The positioning locking component optimizes the fixing way between a contact pad and an adjusting subplate, cannot result in environmental pollution and deformation of the contact pad, and guarantees the measurement precision of an empty and load vehicle adjustment device.

Description

technical field [0001] The invention relates to mechanical technology, in particular to a positioning and locking assembly, a cross beam device and a railway freight car. Background technique [0002] At present, railway freight cars are equipped with an empty-load vehicle adjustment device on the car body, and the contact of the empty-load vehicle adjustment device senses the change in the height of the bogie sleeper spring with the load of the vehicle under different working conditions, which is used as a control signal to control the brake. The size of the cylinder air pressure, so that the vehicle can obtain the corresponding braking force under different load conditions, and avoid various failures caused by the mismatch of the braking force under different working conditions of the vehicle when the vehicle is empty or heavy. [0003] In order to make the empty-load truck adjustment device 1 realize the above-mentioned functions, it is necessary to set up a cross beam de...
