Technical Field

The utility model belongs to the technical field of railway vehicle, concretely relates to bogie and railway vehicle with rubber spring hangs.

Background

The statements herein merely provide background related to the present disclosure and may not necessarily constitute prior art.

Currently worldwide, most countries have a rail gauge of 1435mm, but some countries have a considerable number of other gauge lines. For example, the gauges used by national lines in africa and south east asia are mostly 1000mm and 1067 mm. The railway line conditions in the areas are often rugged, uneven and multi-curve, and the bearing capacity is poor. Similarly, in the case of poor railway line conditions, higher demands are being made on the bogies of railway vehicles.

The inventor knows that the existing bogie of the railway vehicle generally adopts the standard rail steel spring suspension bogie technology, the damping and limiting effects are poor, the bogie is difficult to adapt to the type of rails, and the good effect cannot be obtained; and the existing bogie can not be adapted to the rails with different gauges, and the application range is poor.

Disclosure of Invention

The purpose of this disclosure is to provide a bogie and railway vehicle with rubber spring suspension, can satisfy the requirement of the operational behavior in rugged and multi-curve line, can be applied to the line of two kinds of gauges.

In order to achieve the above purpose, a first aspect of the present disclosure provides a bogie with a rubber spring suspension, which includes a bolster assembly and two side frames arranged side by side, wherein two wheel assemblies are rotatably mounted between the two side frames, and a rotation axis of the wheel assemblies is perpendicular to the side frames.

The swing bolster comprises a swing bolster body, a side frame, a groove, a V-shaped rubber spring and a swing bolster, wherein the swing bolster body is provided with a swing bolster, the swing bolster body is provided with a swing bolster.

The swing bolster is constituteed between two sets of V-arrangement rubber spring of same end and is the contained angle and arranges, and two sets of V-arrangement rubber spring can be respectively towards the oblique top extrusion swing bolster of swing bolster constitution and constitute to the gravity of transmission vertical direction and the extrusion force of horizontal direction.

As a further improvement of the first aspect, spring adjusting base plates are arranged between the side walls of the grooves and the V-shaped rubber springs, and the number of the spring adjusting base plates can be changed so as to adjust the height of the swing bolster assembly in the vertical direction.

A second aspect of the present disclosure provides a railway vehicle utilizing the truck with rubber spring suspension.

The beneficial effects of one or more of the above technical solutions are as follows:

a suspension damping system of the bogie adopts V-shaped rubber springs which connect the swing bolster and the side frame, drive traction force and braking force, provide elastic support in the vertical direction and play roles of flexible connection and limiting in the longitudinal direction and the transverse direction.

The rubber spring is convenient to install, free of maintenance for the whole life, compact in installation space and capable of effectively reducing the dead weight of the bogie. The vehicle body and the bogie can be connected through the plane center plate and the clearance side bearing, the suspension system adopts a rubber spring, and the vehicle has good dynamic performance on rugged and multi-curve lines. When the swing bolster and the side frame vertically move relatively, the rubber spring deforms, the matching surface of the swing bolster and the side frame is not abraded, and maintenance is facilitated.
