Guide rail type railway vehicle bogie guiding device and railway vehicle

Abstract

The invention provides a guide rail type railway vehicle bogie guide device and a railway vehicle, the guide rail type railway vehicle bogie guide device comprises a group of symmetrically arranged first guide assemblies, each first guide assembly comprises a first crank arm and a first guide wheel, one end of each first crank arm is connected to a walking wheel of the railway vehicle, and the other end of each first crank arm is connected to a second guide wheel of the railway vehicle; the other end of the first guide wheel is connected to the first guide wheel, and the first guide wheel is arranged in front of the walking wheel; the second guide assemblies are symmetrically arranged, each second guide assembly comprises a second crank arm and a second guide wheel, one end of each second crank arm is connected to a walking wheel of the railway vehicle, the other end of each second crank arm is connected to the corresponding second guide wheel, and the second guide wheels are arranged behind the walking wheels; the two ends of the transverse connecting rod are hinged to the two first crank arms or the two second crank arms respectively. The structure is simplified, the unsprung weight is reduced, the cost is saved, and the dynamic performance of the bogie is improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicle guiding devices, in particular to a guide rail type rail vehicle bogie guiding device and a rail vehicle. Background technique [0002] The bogies required for rail vehicles used in medium and low-volume urban rail transit systems mainly include: a ring bearing installed at the bottom of the center of the axle, a guide frame is installed under the ring bearing, and two sets of guide frames are installed on the guide frame. The guide wheel arranged on the side of the guide rail is equipped with a steering rod between the guide frame and the crank arm of the wheel, and the two wheels are connected by a trapezoidal steering mechanism. [0003] When a rail vehicle needs to pass through a curved road section, the guide wheel drives the guide frame to rotate relative to the ring bearing through the guide force of the guide rail, and the steering rod rotates with the guide frame to drive the corresp...

AI Technical Summary

Problems solved by technology

[0004] However, the inventors have found that the existing guide device includes guide wheels, guide frames, ring bearings, and steering rods, and has many parts, complicated structure, heavy weight, high production and post-maintenance costs, and does not meet the requirements of light weight vehicles. Quantification and low-cost policy direction, and the high unsprung mass of the guide device also deteriorates the stability and safety performance of the bogie
