Problems solved by technology

This structure is simple and easy to disassemble, but there are the following problems: 1) The length of the single tie rod is limited, and it is difficult to pass the curve and the ramp; 2) The structural strength of the end of the frame is required to be high, resulting in a complicated frame structure
However, the middle traction pin 60 of the double-rod traction device is a friction pair, which produces wear and tear and requires regular maintenance and maintenance; in addition, the structure is more complicated, the parts are many, the manufacturing precision is high, and the manufacturing cost is high; and the installation and disassembly are inconvenient. high maintenance cost

Embodiment Construction

[0033] The core of the present invention is to provide a single-rod traction device. Through structural optimization design, the single-rod traction device has the characteristics of simple and reliable structure, easy disassembly and assembly, and can effectively control manufacturing and maintenance costs. The present embodiment will be described in detail below in conjunction with the accompanying drawings.

[0034] See figure 2 with image 3 ,in, figure 2 It is a schematic diagram of the overall structure of the single-rod traction device described in this embodiment, image 3 yes figure 2 top view.

[0035] Such as figure 2 with image 3 As shown, the traction device is a single-rod structure, and the rod body is located below the motor 5 and installed between the first beam of the frame (ie, the traction beam 61 of the bogie) and the vehicle body 7 . Among them, the vehicle body fifth wheel 1 is fixed on the car body 7, and the frame fifth wheel 2 is fixed on ...

Abstract

The invention discloses a single-draw-bar traction device used for an engine. The traction device comprises an engine body traction seat, a frame traction seat and a traction bar, wherein the engine body traction seat is fixedly arranged on an engine body, and the frame traction seat is fixedly arranged on a traction beam of a steering frame. Two ends of the traction bar are respectively in elastic connection with the engine body traction seat and the frame traction seat through two traction assemblies, and no gap is reserved lengthwise of the traction bar in terms of the elastic connection. On the basis of ensuring curve and hill passage performance, the traction device is simple and reliable in structure and easy to demount and mount, and manufacturing and maintenance costs can be controlled effectively. On the basis, the invention further provides an engine provided with the single-draw-bar traction device.

Description

technical field [0001] The invention relates to a traction device for a locomotive vehicle bogie, in particular to a single pull rod traction device and a locomotive using the traction device. Background technique [0002] The traction device is mainly used to connect the car body and the frame to transmit traction and braking force, and to adapt to the rotation of the car body relative to the bogie. At present, the traction structures commonly used for high-power AC drive locomotives are central push-pull single-tie rods and double-tie rods. [0003] In the traditional end single pull oblique rod traction device, its single pull rod is installed on the traction seat at the end of the car body and frame through a traction rubber joint. This structure is simple and easy to disassemble, but there are the following problems: 1) the length of the single tie rod is limited, and it is difficult to pass through curves and ramps; 2) the structural strength of the end of the frame i...
