Abstract

The invention provides a traction pin for a locomotive traction device. The traction pin comprises a cylindrical pin body. A positioning plate whose section area is larger than that of the pin body is fixed at the top end of the pin body. A second positioning plate is sleeved at the bottom end of the pin body. The second positioning plate is matched with the first positioning plate to axially fix the pin body. The second positioning plate can coaxially rotate relative to the pin body. The pin body sequentially comprises a first shaft section and a second shaft section from the top end to the bottom end. The diameter of the first shaft section is larger than that of the second shaft section. A separating groove is formed on the side of the first shaft section and along the circumferential direction. The separating groove separates the first shaft section into a first section and a second section. The traction pin has the advantages that abrasion borne by the pin body is even, eccentric abrasion is reduced, the service life of the traction pin is prolonged, the circumstance that a joint bearing is stuck in the worn-out groove and cannot be demounted is avoided, and the traction pin is convenient to mount and demount.

Description

technical field

[0001] The invention relates to the manufacturing technology of railway vehicle components, in particular to a traction pin for a locomotive traction device and a traction device. Background technique

[0002] figure 1 It is a structural schematic diagram of a multi-link traction device in the prior art; figure 2 for figure 1 Middle A-A sectional view; such as figure 1 and figure 2 As shown, in the locomotive multi-link traction device, one end of the drawbar 1 is fixedly connected to the car body (not shown in the figure), and the other end is hinged to the crank arm 13 on the bogie through the connecting pin 12 to transmit the traction force of the locomotive. and braking force; that is, the connecting pin 12 runs through the drawbar 1 and the crank arm 13, and on the connecting pin 12, a joint bearing 14 is also sleeved between the connecting pin 12 and the crank arm 13, so as to adapt to the drawbar through the joint bearing 14. 1 and the relative ...
