Abstract

The invention discloses a suspension empty rail freight train bogie wheel axle box structure which includes an axle box with an axle, A bearing is arranged between that axle and the axle case, Awheelsare arranged at both ends of the axle, the top of the axle box is equipped with a suspension connected with a steering frame mechanism. The differential is not set, Wheels are made of steel, becausesteel wheels of the structure do not have a wheel rim structure, easy to bend, axle box assembly is also a brand new structure, Conventional axle box assemblies are located on both sides of the wheels, The axle box assembly design is located on the inner side of the two wheels, which is convenient to reduce the volume and can concentrate the force. The primary suspension adopts the secondary steelcircular spring, which is located on the inner side of the two wheels. By matching the wheel tread shape and the rail shape, as well as the damping and eccentric action of the primary suspension, thetrain smoothly adapts to the transformation of the straight line and the curve.

Description

technical field

[0001] The invention relates to the technical field of locomotives, in particular to a bogie wheel-to-axle box structure of a suspended empty rail freight train. Background technique

[0002] In the existing empty rail bogie, the wheel pair is an independent wheel separated from the left and right, and the two left and right wheels are connected by a differential to meet the requirements of different speeds of the left and right wheels when passing a curve; the wheels are composed of a solid rubber wheel, a hub, a half Shaft, skeleton oil seal, semi-shaft bushing, tapered bearing, etc., and this structure leads to high production cost and short service life when the freight is heavy. Thinking puzzles. Contents of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned problems existing in the prior art, and propose a bogie wheel-to-axle box structure of a suspended empty rail freight train, which is not provided with ...
