Problems solved by technology

[0003] The current vehicle transmission coupling is a simple oblique superposition of rubber and metal layers, especially the rubber layer is a whole solid rubber layer; the radial (Z direction) and The stiffness performance in the lateral direction (X direction) is very large and cannot meet the operating requirements of the vehicle transmission, so it is necessary to improve it

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] like Figure 1 to Figure 2 As shown, the rail vehicle coupling wedge-shaped rubber block includes a right L-shaped end plate 1, a rubber layer 2, a metal separator 4, a left L-shaped end plate 5, and a wedge-shaped metal block 3 with a threaded sleeve 6 in the middle , the rubber layer 2 and the metal separator 4 are staggered and bonded in an oblique arrangement and located between the L-shaped end plate and the wedge-shaped metal block 3, the angle α between the left L-shaped end plate 5 and the right L-shaped end plate 1, the The angle is designed differently according to the size and angle of the interface on the coupling and the radial and transverse rigidity of the product. The angle range is generally 40° to 50°, and the α angle designed by the present invention is preferably 42°.

Abstract

The invention relates to a coupler wedge-shaped rubber block used for railway vehicles. The coupler wedge-shaped rubber block comprises a right L-shaped end plate, rubber layers, metal partition plates and a left L-shaped end plate, as well as a wedge-shaped metal block in the middle part with a thread sleeve, wherein the rubber layers and the metal partition plates are arranged in an overlapping and inclined manner and are bound and positioned between the L-shaped end plate and the wedge-shaped metal block; the included angle alpha between the left L-shaped end plate and the right L-shaped end plate is 40 degrees to 50 degrees, and the middle parts of the rubber layers are provided with through holes; and the rotation direction of the thread sleeve 6 is determined according to the installation manner of the coupler wedge-shaped rubber block, to ensure that the thread sleeve does not extrude out after the installation of the coupler wedge-shaped rubber block. The coupler wedge-shaped rubber block adopts the above structure to play the role of vibration damping and cushioning, the radial direction and transverse stiffness of the coupler wedge-shaped rubber block are matched, and the deflexion and displacement of two shafts are better compensated; and the rotation direction of the thread sleeve is adjusted so as to ensure that the thread sleeve does not extrude in the installation and application process of the coupler wedge-shaped rubber block.

Description

technical field [0001] The invention relates to a rail vehicle damping component, in particular to a wedge-shaped rubber block for a coupling of a rail vehicle. Background technique [0002] Generally, in order to ensure the synchronization and stability of the vehicle transmission, 12 wedge-shaped rubber blocks are installed at the coupling of the vehicle. They are used to connect two shafts (driving shaft and driven shaft) in different mechanisms to make them rotate together to transmit torque. , while using its elastic deformation to compensate for the deflection and displacement of the two shafts, and it also has the functions of buffering, damping and improving the dynamic performance of the shafting. The wedge-shaped rubber block is designed as a V-shaped and multi-layer rubber composite structure. The load acts on the product in the radial direction (Z direction), transverse direction (Y direction) and longitudinal direction (X direction). This type of product can...
