Abstract

The invention provides a wheelset lifting device and a bogie with the same. The wheelset lifting device is arranged on a vehicle bogie, wherein the bogie comprises a frame, a wheelset, an axle box anda brake caliper; the frame is matched with the wheelset; both ends of the wheelset are each provided with an axle box; and the brake caliper is arranged on the outside of the rotating shaft of the wheelset for braking the wheels of the wheelset. The wheelset lifting device comprises a first connecting part and a lifting arm, wherein the lifting arm is arranged on the rear cover of the axle box and is located on the inside of the rotating shaft of the axle box, and the lifting arm and the rear cover of the axle box are of an integrated structure; and the lifting arm is connected with the firstconnecting part, so that the lifting tool simultaneously lifts the frame and the axle box through the lifting arm, so as to lift the whole bogie. The wheelset lifting device solves the problem that the setting mode of the wheelset lifting device in the prior art is inconvenient for lifting the vehicle bogie.

Description

technical field [0001] The invention relates to the field of rail train manufacturing, in particular to a wheel set lifting device and a bogie with the same. Background technique [0002] Existing rail vehicle bogies are generally equipped with special wheelset lifting devices to facilitate the overall lifting of the bogies. At present, due to the limitation of line conditions and design space of existing rail vehicles, the bogies of most vehicles adopt the external brake caliper structure. [0003] However, the bogie with the external structure of the brake caliper has the following problems in actual processing and use: [0004] (1) This structure will result in a narrow wheel axle space, which will bring difficulties to realize the overall hoisting of the bogie, and the overall hoisting of the bogie is the basic requirement that the vehicle needs to meet. [0005] (2) The wheel set hoisting on the existing swivel bogie usually adopts an external arrangement, which coope...
