Embodiment 1

[0036] see Image 6 , 7 As shown, the technical solution provided in this embodiment is applied to a Y25 bogie.

[0037] One free arm of the L-shaped size adjuster 3 has an eyelet 5 to which the first pull rod 4 and / or the second pull rod 7 is connected, while the other free arm of the L-shaped size adjuster 3 is connected to the axle box luggage rack 2 on.

[0038] The axle box luggage rack 2 is an integral part of the axle box 1, which is connected to the axle box 1 by welding. Alternatively, the axle box luggage rack 2 is connected to the axle box 1 by means of screw connection. Alternatively, the axle box luggage rack 2 is cast integrally with the axle box 1 as a component of the axle box 1 .

[0039] Based on the size adaptor 3 is firmly connected to the axle box luggage rack 2 by means of threads. Alternatively, the size adjuster 3 and the axle box rack 2 can be connected by pins or as castings, then the axle box 1 is a single piece including the axle box rack 2 and...

Embodiment 2

[0047] see Figure 8 , 9 As shown, as in the first embodiment, the technical solution provided in this embodiment is applied to the Y25 bogie.

[0048] The L-shaped size adjuster 3 is connected to the axle box luggage rack 2, wherein the bottom short arm and the long free arm of the size adjuster 3 together with the holes 5 are connected to the first pull rod 4 (or the second pull rod 7) to form an L-shaped, short The arm is the base of the sizer 3.

[0049] The axle box luggage rack 2 is a constituent part of the axle box 1 . The axle box luggage rack 2 can be connected with the axle box 1 by welding. Alternatively, the axle box luggage rack 2 is connected to the axle box 1 by means of screw connection. Alternatively, the axle box luggage rack 2 is cast integrally with the axle box 1 as a component of the axle box 1 .

[0050] The arm of the size adjuster 3 is firmly connected to the axle box luggage rack 2 by means of a screw connection. Alternatively, the connection o...

Abstract

The embodiment of the invention provides a railway traction locomotive dual-axis bogie with a cross connector capable of radially regulating the wheel group, including: two crossed pull rods ( a firstpull rod 4 and a second pull rod 7) performing diagonal connection to two wheel groups of one bogie, wherein one ends of the first pull rod 4 and the second pull rod 7 are connected to an L-shaped size tuner 3, the size tuner 3 is connected to an axle box 1 through an axle box baggage carrier 2. the railway traction locomotive dual-axis bogie with a cross connector capable of radially regulatingthe wheel group can achieve increased curve guide performance, enhanced operational stability, reduced external force function and reduced abrasion between the wheels and rails.

Description

technical field [0001] The invention relates to a railway locomotive, in particular to a double-axle bogie of a railway traction locomotive. Background technique [0002] In order to reduce the external force and the wear between the wheel and the rail, in the field of railway locomotives, the loose connection between the bogie frame and the wheel set is widely used, or the wheel set is relatively loose, in order to create a radial adjustment during the curve transition. condition. In addition to meeting the requirements of dynamic conditions, its application in railway locomotives also needs to meet the requirements of easy maintenance, inspection, replacement and adjustment, so that these tasks are simple and easy to do without trouble. [0003] In the suspension mode, the radial adjustment of the wheel set during the curve transition can be achieved by the wheel set guiding method, so that sufficient elasticity can be maintained in the longitudinal direction, where the s...
