Problems solved by technology

At present, due to the advantages of fiber-reinforced composite materials such as high specific strength, corrosion resistance and high fatigue life, some vehicles have begun to use composite elliptical leaf springs in batches, but it is difficult to integrally form the coil ears and composite material leaf springs. The reliability of the free sliding and rolling of the ends of the lower spring leaf is not good and it is extremely easy to wear

Embodiment Construction

[0033] The following is attached Figure 1-5 The present invention is further described in detail.

[0034]The end connection device of the leaf spring, wherein the leaf spring includes two upper and lower semi-elliptical spring leaves, which are respectively the upper spring leaf 1 and the lower spring leaf 2, and the leaf spring is formed by pairing the upper spring leaf 1 and the lower spring leaf 2 to form an ellipse Shaped leaf spring. The end connecting device of the plate spring comprises an upper metal sleeve 5 and a lower metal seat 3 connected between the ends of the upper spring leaf 1 and the lower spring leaf 2, the upper metal sleeve 5 is fixed on the lower metal seat 3 and the upper metal There is a rubber bushing 4 between the sleeve 5 and the lower metal seat 3, and the deformation of the rubber bushing 4 is used to meet the longitudinal displacement between the upper spring piece 1 and the lower spring piece 2 when bearing the load and make the upper spring ...

Abstract

The invention belongs to the technical field of vehicle connection damping parts, and discloses an end connecting device of a plate spring, which comprises an upper metal sleeve and a lower metal seat which are connected between the end of an upper spring piece and the end of a lower spring piece, the upper metal sleeve is fixedly connected to the lower metal seat, and a rubber bushing is arranged between the upper metal sleeve and the lower metal seat. The longitudinal displacement between the upper spring piece and the lower spring piece is met through the deformation of the rubber bushing when the load is borne, and the upper spring piece and the lower spring piece can rotate around the two ends. The invention further relates to a mounting method of the plate spring end connecting device and an end deformation method of the plate spring.

Description

technical field [0001] The invention relates to an end connection device of a leaf spring, in particular to an end connection device of a series of composite material leaf springs for rail vehicles, and belongs to the technical field of vehicle connection shock absorbing components. The invention also relates to a method for installing the end connection device of the leaf spring and a method for deforming the end of the leaf spring. Background technique [0002] Vehicles are usually used to carry passengers or transport goods. In order to ensure the comfort of passengers and the safety of goods transportation, an elastic connection damping device is usually provided between the vehicle body and the wheel axle, semi-elliptical leaf springs and elliptical springs. Leaf springs, as commonly used elastically connected damping leaf springs, have been widely used in the connection and shock absorption of vehicle-related components, especially in the end connection devices of a se...
