Embodiment Construction

[0037] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, if the words "up", "down", "left" and "right" appear in the following, it only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.

[0038] A locking mechanism for variable gauge wheel sets, such as figure 2 As shown, it includes a fixed sleeve 10 with a cylindrical hole, a relief sleeve 8 with a spherical groove, a limit ball 7 , a return spring 9 and a chuck 6 . Wherein the fixing sleeve 10 is fixed relative to the axle 5 and has 6 cylindrical holes in the circumferential direction. The limit ball 7 is installed in the cylindrical hole through clearance fit, and cooperates with th...

Abstract

The invention discloses a variable-track-gauge wheel set and a locking mechanism thereof. The locking mechanism of the variable-track-gauge wheel set is arranged between a wheel hub and a wheel axle and used for locking wheels at different positions of the wheel axle to adjust the distance between the two wheels. A guiding structure for guiding the wheels to move axially is arranged on the wheel axle, and the locking mechanism adjusts the wheels to designated positions and then locks the wheels at the designated positions. On the premise that a variable track gauge is achieved, it is ensured that the wheel set has enough flexibility, reliability and accuracy.

Description

technical field [0001] The invention relates to a gauge variable wheel set and a locking mechanism thereof, belonging to the field of rail vehicle bogies. Background technique [0002] It is an urgent problem to be solved in international and interregional intermodal transportation to solve the through-running of railway vehicles in different sections of gauge. The use of variable gauge bogie technology is an effective method. The current research on variable gauge bogies in our country It has just started, and it is particularly important to develop and develop variable gauge bogies suitable for my country's national conditions. [0003] The variable gauge wheel and its wheel locking mechanism are the key parts of the research and development of variable gauge technology. It must be ensured that it has sufficient flexibility, reliability and accuracy. If the above performance cannot be guaranteed, it will not only fail to achieve variable gauge. Therefore, the design of the...
