Embodiment Construction

[0018] The spring element 2 shown in the figure is a so-called "leaf spring", which can be used both as a separate support spring and as an additional spring in combination with a pneumatic spring for supporting the bodywork of a rail vehicle.

[0019] The spring element 2 is essentially formed by an elastic spring body 4 . It is fixed between two rigid end members 6 , 8 arranged at a variable distance from each other.

[0020] The spring body 4 has a rotationally symmetrical cross section. Longitudinal section ( figure 2 and Figure 4 ) represents a generally biconvex surface line. Owing to the cavity 10 overall a U-shaped longitudinal section results.

[0021] The spring body 4 is made of rubber or an elastic material with comparable elasticity.

[0022] Of the rigid end elements 6 , 8 , the "upper" element 6 is designed as a disc and the "lower" element 8 is designed as a ring. That is to say, the "lower" end piece 8 has a hole 8a in the middle, whereby the cavity 10...

Abstract

The spring for use in rail vehicle suspensions comprises a rubber sphere (4) mounted between top (6) and bottom (8) plates. The sphere has longitudinal (14a - 14c) and transverse (16a - 16c) ribs over its surface which enclose polygonal fields (18a - 18c) between them.

Description

technical field [0001] The invention relates to a spring element, in particular a so-called "leaf spring" which can be used in rail vehicles alone or in combination as an additional spring and a pneumatic spring. Background technique [0002] Patent document DE 35 09 923 C2 discloses a spring element or spring for a vehicle suspension. The main features of this spring element are explained in the opening paragraphs of the following detailed description. [0003] The outer contour of the rubber body of the known spring element is smooth. The bearing surface of the rubber body is made smaller and larger by means of constantly changing vertical forces. The rubber body rolls on the base by the additionally introduced horizontal force. The result of these two forces is a relative movement between the rubber and the seat, and thus friction and wear of the rubber. Contents of the invention [0004] The spring elements disclosed in the above prior art will be further improved ...
