Transverse stop for rail train

Abstract

The invention relates to a transverse stop for a rail train. The transverse stop comprises a top cover, a rubber part and a base; the top cover comprises a wearing plate and a mandrel coaxially arranged on the wearing plate, one end of the mandrel is fixed to the lower surface of the wearing plate, the other end of the mandrel is embedded to the top end of the rubber part, the outer wall of the upper portion of the rubber part contracts gradually from bottom to top, and an included angle is preset between the upper outer wall and the lower surface of the wearing plate; the bottom of the rubberpart is fixedly connected with the base, a groove is formed in the center of the bottom wall, a cavity is formed between the rubber part and the base in a defined mode, and an exhaust hole communicated with the cavity is formed in the base. The transverse stop for the rail train is capable of ensuring uniform rigidity of all turning angles when the train passes a small curve rail path and prolonging the service life of the train while ensuring comfort of the train.

Description

Technical field [0001] The invention relates to the technical field of rail transit equipment, in particular to a lateral stop for rail trains. Background technique [0002] Existing rail train bogies and between the frame and the car body are installed with lateral stops, which are used to buffer the lateral vibration and impact of the car body when the train passes a curve and curve, and the lateral stops are between the bogie and the car body. It has the effect of reducing vibration and noise, which can improve the running quality of rail trains and improve the comfort performance of trains. [0003] The lateral stop requires its rigidity during use. The structure of the lateral stop in the prior art is mainly composed of a wear plate, a rubber part and a base. The rubber is fixed between the wear plate and the base. When passing through a curved curve, the wear plate is impacted and tilted, and the rubber part is driven to deform to buffer the lateral shock of the car body. H...

AI Technical Summary

Problems solved by technology

However, the design of the transverse stop in the prior art only considers the axial impact it receives during use, that is, its stiffness in the axial direction. The contact area between the wear plate and the rubber is relatively large, and even the bottom surface of the wear plate Fully fixed to the top of the rubber, suitable for trains in large displacement and large curved track lines (the radius of the curve is large)

However, when the train passes through a small curved track line (the radius of the curve is small), the wear plate is inclined greatly, the deformation of the rubber parts is large, and the impact in the radial direction is relatively large, which may cause the rubber parts to break or even fail. and other issues that affect the comfort of the train
