Embodiment Construction

[0016] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] like Figure 1~3 As shown, the fishing rod-type variable gauge locking mechanism is installed on the inner side of the wheel 2, and includes a limit post 4 and an axle 1. The wheel 2 is installed on the axle 1, and the sleeve 8 is fixed on the axle by shrinking 1, the sleeve 8 is equipped with a relief cylinder 9 and a relief plate 11, and a relief spring 7 is arranged between the sleeve 8 and the relief cylinder 9, and the relief cylinder 9 is triggered and unlocked by the ground gauge changing device. The fishing rod-type variable gauge locking mechanism is relatively independent, and can be hot-fitted on the axle after being assembled. The position columns 4 are evenly arranged along the circumference to withstand relatively high wheel-rail lateral force, and at the same time, the machining accuracy of the mechanism is not high, a...

Abstract

The invention provides a fishing rod type variable gauge locking mechanism, and belongs to the technical field of vehicle bogies. The fishing rod type variable gauge locking mechanism comprises a vehicle axle and wheels, wherein the wheels are separately fixed to two ends of the vehicle axle through a corresponding wheel hub; the axial width of each wheel hub is greater than the thickness of each wheel, and each wheel hub is provided with a narrow gauge and wide gauge limiting structure with a limiting column; a narrow gauge blind hole and a wide gauge blind hole are formed in the outer diameter surface of each wheel hub in the radial direction; sleeves are separately fixed to the wheel axle, on the inner side of each wheel; the inner diameter of each sleeve is in clearance fit with the outer diameter of the corresponding wheel hub; a relieving cylinder is arranged on the outer diameter of each sleeve; a relieving disk is arranged at the end part of each relieving cylinder; oblique fishing rods are uniformly arranged on each relieving disk in the circumferential direction; an axial through hole is formed in the front end of each sleeve along the circumference, and a spring bracket is arranged in the middle part of each sleeve; a relieving spring is arranged between each sleeve and the corresponding relieving cylinder; and an oblique penetrating hole is formed in each limiting column. The fishing rod type variable gauge locking mechanism disclosed by the invention is mainly used in an occasion that a narrow gauge is different from a wide gauge.

Description

technical field [0001] The invention belongs to the technical field of vehicle bogies, and in particular relates to a locking mechanism for variable-gauge bogies. Background technique [0002] Due to the increasing frequency of international freight, cross-border transportation encounters the problem that the railway gauges are different and cannot be passed through. It is necessary to change the gauge truck bogie. Although there are many kinds of locking mechanisms for the variable gauge truck bogie Various, but there are also many shortcomings, as introduced in the patent CN201310137008; some locking mechanisms use balls to limit the force area, which is not conducive to resisting the lateral force of the large load wheel and rail; Or the ring groove is provided on the wheel hub only for arranging a limit piece, which not only reduces the strength of the axle hub but also causes uneven lateral force. Contents of the invention [0003] The object of the present invention...
