Abstract

The invention provides a low floor tramcar steering bogie, belongs to the technical field of railcar steering bogies and particularly relates to a low floor independent rotation wheel steering bogie. The low floor tramcar steering bogie can be used for effectively solving the problems such as difficulties in realizing synchronous rotation of left and right wheels, and recovery of gravity restoring force and longitudinal creep force. The low floor tramcar steering bogie is of an H-shaped welding structure, has a symmetrical structure and is provided with side beams and a cross beam; a wheel group coupling unit is of a shaft box / gear box integrated structure; a lower box body and a coupling shaft sleeve are of an overall structure; one end of an upper box body is provided with a shaft box / gear box pull rod base, and the shaft box / gear box pull rod base and a conical rubber spring of a primary suspension device form a single pull rod shaft box positioning structure; a semi-shaft on the inner side of the wheel group coupling unit is provided with a cylindrical gear; two ends of a coupling gear shaft are provided with shaft gears matched with the coupling gear shaft; one side of the coupling gear shaft is further provided with a bevel gear; a driving motor is connected with a power input shaft by virtue of a universal shaft; the coupling shaft sleeve is provided with a bearing support which is of a simply-supported beam structure; the power input shaft is connected with the bearing support by virtue of a bearing. The low floor tramcar steering bogie is mainly applied to tramcars.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle bogies, in particular to low-floor independent rotating wheel bogies. Background technique [0002] The use of 100% low-floor trains is the choice of medium and low-volume ground rail transit in many cities at home and abroad. To achieve 100% low-floor trains, independent rotating wheel technology or small-diameter through-axle technology can be used. Due to the serious wear of small wheel diameter wheels, most low-floor tram bogies adopt independent rotating wheel bogie technology to ensure the realization of low-floor passenger compartments. my country is also gradually introducing, digesting and promoting this low-floor train technology. [0003] At present, the main type of low-floor vehicles in the world basically adopts Mc+F+Tp+F+Mc (single floating vehicle) or Mc+Tp+Mc (single vehicle) structural type. Mc is a power vehicle with control rooms at both ends of the vehicle; Tp vehicle is...
