Embodiment Construction

[0021] The accompanying drawing shows a specific embodiment of the present invention, and the present invention will be further described below through the accompanying drawing and the embodiment.

[0022] figure 1 Provided a specific embodiment of the present invention, as can be seen by accompanying drawing, the present invention is a kind of novel rail transit traction method, adopts soft elastic composite material as the elastic damping structure of traction system; There is an elastic nylon sleeve 2 for the central pin between the traction pin 1, and the rigid impact between the central pivot block 6 and the traction pin 1 can be avoided through the nylon sleeve 2 with certain elasticity, and the traction pin 1 can be connected with the center when the vehicle passes a curve. Unconstrained rotation between pivot blocks 6. Between the central pivot block 6 and the bogie frame 4, a traction pad 3 is provided in the front and rear along the traction direction. The traction ...

Abstract

The invention relates to a traction method and a system for rail transportation. A soft elastic composite material is used as an elastic vibration-damping structure; a center pivot block is connected with a traction pin by an elastic nylon center pin sleeve, and the nylon sleeve with certain elasticity avoids the rigid shock between the center pivot block and the traction pin and simultaneously realizes the unconstrained rotation between the traction pin and the center pivot block when a vehicle makes a turning; two traction pads are respectively arranged in the front and at the back between the center pivot block and a bogie frame in the traction direction, the traction pads are rubber-metal compound elastic elements, two end plates of the traction pads are respectively provided with a connecting pin, and the connecting pin on the traction pad is directly inserted into a connecting hole for the center pivot block and the bogie frame; and the two traction pads connect the center pivotblock and the bogie frame, transfer traction force and brake force and buffer the shock load in transverse direction, vertical direction and other directions, so that the vehicle has better dynamicalperformance in operation.

Description

technical field [0001] The invention belongs to a traction method and system for rail transit vehicles, in particular to a traction method and system installed between the bogie frame and the car body, which is mainly used to transmit traction force and braking force, and at the same time coordinate the movement of the bogie and car body, ease Vibration and impact loads in all directions, and provide appropriate stiffness performance in all directions to meet the needs of safe operation of the rail transit traction method and system. Background technique [0002] Rail vehicles running on the track will be accompanied by various vibrations and shocks. In order to reduce harmful vibration and shock loads, the vehicle must be provided with a device for mitigating vibration and shock, that is, a spring damping device. The spring damping device on the vehicle can be divided into three categories according to its main function: one is the elastic suspension device that mainly pla...
