Problems solved by technology

During the gauge change process, the wheelset is unloaded and out of contact with the rails, the bogie cannot be centered automatically, and at the same time, the ground gauge change supporting track is vertically uneven and the wheelset is subjected to lateral force, which causes the bogie to deflect to one side incline

Embodiment Construction

[0024] The present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0025] The mechanism described in the present invention is suitable for an end-drive type variable-gauge bogie gauge conversion device. An end-drive type variable-gauge bogie gauge change device is composed of an axle box, an end-surface drive mechanism, and a wheel set. Mechanism and axle box end cover positioning and centering mechanism are assembled. The end face driving mechanism is installed on the bushing through the tapered roller bearing assembly. When the gauge is changed, the wheel and the bushing can follow the end face driving mechanism One body slides axially on the axle to achieve the purpose of variable gauge; the following embodiments are based on the existing variable gauge b...

Abstract

The invention discloses an axle box end cover positioning and centering mechanism for a gauge-changeable bogie. The axle box end cover positioning and centering mechanism for the gauge-changeable bogie comprises a positioning and centering end cover mounting seat, a positioning and centering end cover and a centering roller assembly; four end cover U-shaped grooves are formed in the axle box end cover positioning and centering mechanism for the gauge-changeable bogie; the positioning and centering end cover mounting seat is connected with a locking sleeve bolt of a wheel pair locking mechanismthrough a positioning and centering end cover mounting seat mounting hole; a positioning and centering end cover mounting threaded hole mounted together with the positioning and centering end cover is formed in the positioning and centering end cover mounting seat; the centering roller assembly is mounted on the positioning and centering end cover; and the centering roller assembly rolls on an assorted gauge-changeable driving rail. The axle box end cover positioning and centering mechanism for the gauge-changeable bogie is used for transverse positioning and centering in the gauge changing process and applicable to an end surface driving type gauge-changeable bogie gauge changing device.

Description

technical field [0001] The invention belongs to the technical field of bogie systems, and relates to gauge change technology, in particular to a positioning and centering mechanism for an axle box end cover of a variable gauge bogie. Background technique [0002] With the vigorous development of the Silk Road Economic Belt, my country has carried out larger-scale, higher-level, and deeper regional cooperation with countries along the route, and is committed to building an all-round interconnection network. Among them, railway transportation has increasingly become the most important part of the Eurasian road. However, railways with different gauge specifications in different countries and regions have brought many restrictions to the development of international intermodal transport. [0003] Aiming at railways with different gauges, domestic and foreign are committed to researching a variable-gauge bogie, which can adapt to railways with different gauges by changing the whee...
