Anti-snaking motion device for road-railway dual purpose truck bogie

A road-rail dual-purpose, motion device technology, which is applied in the direction of the lateral relative movement device between the underframe and the bogie, can solve the problem that the anti-snake shock absorber cannot be fixedly connected to the semi-trailer, and the road-rail dual-purpose truck cannot be used for steering. The problems such as the difficulty of setting side bearings and core disks in the frame and bogie can achieve the effect of suppressing the meandering motion, simple structure and low production cost.

Embodiment Construction

[0019] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the technology of the present invention will be further described in detail below in conjunction with the accompanying 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 invention.

[0021] Such as figure 1 , 2 As shown in and 3, an anti-snake motion device for a road-rail truck bogie includes a lateral control rod 1 and an anti-snake shock absorber 2, and the lateral control rod 1 rotates with the road-rail dual-purpose truck bogie 3 connection, a longitudinal stop assembly is arranged on the lateral control rod 1, when the road-rail dual-purpose semi-trailer 4 and the road-rail dual-purpose truck bogie 3 are connected together to form a railway f...

Abstract

The invention discloses an anti-snaking motion device for a road-railway dual purpose truck bogie. The anti-snaking motion device for the road-railway dual purpose truck bogie comprises a transverse control rod and an anti-snaking shock absorber. The transverse control rod is rotatably connected with the road-railway dual purpose truck bogie, a longitudinal backstop assembly is arranged on the transverse control rod, when a road-railway dual purpose semitrailer is connected with the road-railway dual purpose truck bogie in a hanging mode, the end portion of the road-railway dual purpose semitrailer is in contract with the longitudinal backstop assembly on the transverse control rod, one end of the anti-snaking shock absorber is connected with the transverse control rod, and the other end of the anti-snaking shock absorber is connected with the road-railway dual purpose truck bogie. When the road-railway dual purpose semitrailer is connected with the road-railway dual purpose truck bogie in a hanging mode, the longitudinal backstop assembly is in contract with the end portion of the road-railway dual purpose semitrailer, thus, the problem that the anti-snaking shock absorber cannotbe fixedly connected with the semitrailer is effectively solved, and the purposes that the vehicle snaking motion is restrained and the critical speed of vehicle operation is improved are achieved.

Description

technical field [0001] The invention belongs to the technical field of railway freight car bogies, and in particular relates to an anti-snaking motion device for road-rail dual-purpose freight car bogies. Background technique [0002] Installing an anti-snake motion rotary damping device between the car body and the bogie is one of the effective measures to suppress the snake motion of high-speed vehicles. Disc and anti-snag dampers three ways. [0003] For the bogie dedicated to road-rail dual-purpose trucks with ramps for lifting semi-trailers, it is difficult to install side bearings and center plates on the bogie. Fixed connection, but in order to facilitate the rapid conversion of road and rail semi-trailers between road transportation and rail transportation, the anti-snake shock absorber cannot be fixedly connected to the semi-trailer. Therefore, the conventional anti-snaking motion slewing damping device cannot be applied to the bogie of road-rail truck, so it is n...
