Modularly-designed pull rod type traction device

Abstract

The invention discloses a modularly-designed pull rod type traction device. The modularly-designed pull rod type traction device comprises a pull rod and further comprises two end threaded rods and multiple rubber springs, the two ends of the pull rod are in threaded connection with the connecting ends of the end threaded rods and are locked, the rubber springs are strung in sequentially in the direction from the free ends of the end threaded rods to the connecting ends and are limited through limiting check rings on the rods, and on the free ends of the end threaded rods, the rubber springs are limited and locked through glands, gaskets and second hexagon nuts. The device has the beneficial effects that the modular design idea is adopted, longitudinal rigidity changes can be achieved by simply adjusting the number of the metal rubber springs, the rubber springs do not need to be frequently re-designed, design needs of various axle load vehicles can be met, the whole vehicle obtains the good property, the design process is greatly simplified, meanwhile, the large torsion angles in the vertical direction and the transverse direction can be achieved, and the device can adapt to moreworking conditions.

Description

technical field [0001] The invention relates to a modular design pull rod type traction device, which belongs to the technical field of rail transportation. Background technique [0002] At present, the vehicle profile part in the field of rail transit is often realized in the form of a bogie, and the transmission of longitudinal force between the bogie and the car body is mainly realized by using a central traction device or using a bolster plus a traction rod. [0003] Suspended monorail vehicle bogies often use bolsters and traction rods. The current conventional traction rod structure is a steel torsion bar with round holes at both ends, and rubber nodes are installed in the holes to realize the elastic connection between the car body and the bogie. . The traction rods of this structure cannot achieve a large vertical and lateral torsion angle at the same time, and the rubber node type traction rods are difficult to obtain a small rigidity, while the weight of the suspe...

AI Technical Summary

Problems solved by technology

The traction rods of this structure cannot achieve a large vertical and lateral torsion angle at the same time, and the rubber node type traction rods are difficult to obtain a small rigidity, while the weight of the suspended monorail vehicle is often light, only three to three times that of traditional rail transit vehicles. One-fourth, the traction rod with too large rigidity will cause the suspended monorail vehicle to bear a large impact during traction and braking, which is not conducive to the performance of the whole vehicle
