Problems solved by technology

[0005] However, there are certain defects in the traction device of the above-mentioned structure: First, because the pin body 12 is a rigid structure, it needs to be carried by bearings, so the gap between the pin body 12 and the bearing is prone to impact, thus affecting the traction force and braking force In addition, there are components such as crank arms, pin bodies, and rods, and the structure is relatively complicated; in addition, the traditional way of connecting the traction device, because the connected rods cannot bear the weight of the bogie itself, makes the bogie and the car body It cannot be directly hoisted as a whole, and it is inconvenient to rescue and transfer after derailment

Abstract

The invention provides a traction device and a rail car. The traction device comprises a car body fastener, an alloy bushing, a rubber traction pin joint and a bogie fastener, wherein the car body fastener is fixedly connected with a car body traction beam, and at least one traction pin is arranged at one side of the car body fastener, which is far from a car body; the alloy bushing is sheathed outside the traction pin and fixedly connected with the traction pin; the rubber traction pin joint is sheathed outside the alloy bushing, and the rubber traction pin joint orderly comprises an outer wall rigid plate and a rubber layer from the inside to the outeside; and the bogie fastener is fixedly connected with a bogie traction box and fixedly connected with the outer wall rigid plate of the rubber traction pin joint. Due to the adoption of the technical scheme, the invention simplifies the structure and effectively transmits traction force and brake force.

Description

technical field [0001] The invention relates to rail car traction technology, in particular to a traction device and a rail car. Background technique [0002] Rail cars are mainly used for the transportation of construction materials and personnel during railway construction and maintenance. It can also be used for shunting operations on the lines in the depot and on the main line, or the rescue traction of accident trains, the transportation of equipment and materials, and the traction operations of other unpowered rail vehicles. [0003] The traction device is an important part installed between the car body and the bogie of the rail car to transmit the traction force of the rail car, the braking force, and the impact force during operation. When the electric transmission rail car is working, the power transmission path is: traction motor → wheel axle box → bogie frame → traction device between the car body and bogie → coupler → towed object. Therefore, the basic require...
