Problems solved by technology

[0008] The object of the present invention is to propose a new method for fixing rubber pile positioning pins and a new rubber pile, aiming at the problem that the weld seam cracks easily occur during the operation of the existing rubber pile positioning pins. The fixing method of the rubber stack positioning pin and the new rubber stack can further improve the overall structure of the rubber stack positioning pin and effectively prevent weld cracking

Embodiment 1

[0032] by attaching figure 1It can be seen that the present invention relates to a rubber stack, comprising an upper metal mounting plate 1 and a lower metal mounting plate 3, and an upper metal mounting plate and a lower metal mounting plate are arranged between the upper metal mounting plate 1 and the lower metal mounting plate 2 The rubber-metal composite elastic body 3 vulcanized together as a whole; at the same time, rubber stack positioning pins 4 are respectively arranged on the upper metal mounting plate and the lower metal mounting plate; The inner surface of the metal mounting plate 3 protrudes outward, and then the rubber stack positioning pin 4 is fixedly welded on the upper metal mounting plate 1 or the lower metal mounting plate 3 by welding to form an integrated structure of the positioning pin and the metal mounting plate, and the rubber stack The positioning pin 4 is installed in the mounting hole on the metal mounting plate in the form of multi-sections with ...

Embodiment 2

[0039] The principle of Embodiment 2 is the same as that of Embodiment 1, except that the structure is slightly different. The rubber stack includes an upper metal mounting plate and a lower metal mounting plate, between the upper metal mounting plate and the lower metal mounting plate There is a rubber-metal composite elastic body integrally vulcanized together with the upper metal mounting plate and the lower metal mounting plate; at the same time, rubber stack positioning pins are respectively arranged on the upper metal mounting plate and the lower metal mounting plate; the rubber stack rubber The stack positioning pin is protruding from the inner surface of the rubber stack metal mounting plate, and then the rubber stack positioning pin is fixed and welded on the metal mounting plate by welding to form an integrated structure of the rubber stack positioning pin and the metal mounting plate, and the rubber stack positioning The pins are mounted in the mounting holes on the ...

Abstract

The invention discloses a fixing mode of a multiply rubber spring dowel pin and a multiply rubber spring. The fixing mode of a multiply rubber spring dowel pin is characterized in that a multiply rubber spring dowel pin is fixed on a multiply rubber spring metal installing plate through welding, a dowel pin of a multiply rubber spring extends outwards from the inner surface of the multiply rubberspring metal installing plate, and then the dowel pin is fixedly welded on the metal installing plate through the welding, and an integrated structure of the dowel pin and the metal installing plate is formed; and the dowel pin is installed in an installing hole in the metal installing plate in a manner of multiple section unequal-diameter sections, so that the damage of the dowel column surface of the dowel pin in the installation process of the dowel pin is avoided. According to the fixing mode and the multiply rubber spring, the dowel pins extend outwards from the inner surface, so that thestrength of the pins is improved, the phenomenon of weld joint tearing is effectively avoided, the dowel column surface of the dowel pin is effectively prevented from being damaged by the unequal-diameter sections, so that the performance of the dowel pin is integrally improved.

Description

technical field [0001] The invention relates to a vibration damping part of a vehicle and its assembly method, in particular to a rubber pile positioning pin fixing method and a rubber pile. The rubber pile positioning pin fixing method and the rubber pile can effectively avoid rubber pile positioning pins. The structure is damaged, and the strength is further improved; it belongs to the technical field of vehicle component connection. Background technique [0002] As an important part of the secondary vibration damping system of the locomotive, the secondary rubber stack plays a great role in the safe and stable operation of the locomotive. The structure of the pin has a great influence on the reliability of the rubber stack. Generally, the second-series rubber pile of locomotives is composed of multiple pieces of rubber and metal to form a rubber pile, which provides longitudinal, transverse and vertical stiffness, and especially realizes the transmission of traction and b...
