| description | The embodiment of the invention provides a wheel set back pressure testing device which comprises a center assembly and a back pressure assembly, and the center assembly is located on the outer side of a wheel set and used for fixing and centering the wheel set and applying load to a wheel; the back pressure assembly is located on the inner side of the wheel set. The back pressure assembly comprises a moving table; the mounting plate is detachably and fixedly connected to the moving table; an opening through which an axle passes is formed in one side of the mounting plate; the back pressure sleeve is used for being arranged on the outer dustproof plate between the wheel and the bearing in a sleeving mode and abuts against the end face of the hub; the back pressure sleeve can abut against the side wall of the side, close to the wheels, of the mounting plate. According to the arrangement, the center assembly exerts load on the axle on the outer side of the wheel set, the load is transmitted to the back pressure |
