Walking device of rail car

Abstract

The invention relates to a walking device of a rail car. The walking device comprises a power walking part, a driven walking part and a suspension beam. The suspension beam and the power walking partare connected by a slewing bearing, the suspension beam and the driven walking part are connected by the slewing bearing, and the driven walking part can oscillate in a walking direction of the walking device of the rail car relative to the power walking part. The walking device comprises the three parts: the power walking part, the driven walking part and the suspension beam. The suspension beamis mounted on the power walking part and the driven walking part by the slewing bearing. According to the structure, the walking device of the rail car is flexible to turn and good in curve trafficability characteristic. By adopting frames with two double shafts, one shaft is provided with one wheel. As two frames are arranged, that is, the power walking part frame and the driven walking part frame, the two frames are connected together by using the suspension beam. The slewing bearing is used at a connection of the suspension beam and the frame. When a vehicle passes a turnout and a curve ofa box type rail, the walking device is more flexible to turn and a phenomenon of stagnation or suspension of a single wheel is avoided.

Description

technical field [0001] The invention relates to the technical field of rail transportation, and more specifically, relates to a rail vehicle running device. Background technique [0002] The intelligent rail system belongs to the field of rail transit, and is a miniature rail running mechanism, specifically referring to a suspended rail transit system with a track width of less than 600mm. [0003] The intelligent track system is mostly used in hospital logistics, prison inspection, construction site transportation, factory material transfer, passenger and cargo transportation and other fields. In the existing technology, a typical intelligent rail system is mainly composed of rails and intelligent rail cars. The rails often have bifurcations, which can form a complex road network. Most of the smart rail cars are suspended, and the smart rail cars can run on the track. , to achieve freight or passenger transport. [0004] In the intelligent track system, the intelligent ra...

Problems solved by technology

[0005] At present, typical suspension-type smart railcars generally adopt railway standard four-axle single frame or four-axle double frame. There will be a phenomenon that individual wheels cannot touch the track surface, commonly known as "three legs", and the stability of the smart rail car will be reduced

[0006] In addition, there are other structural defects in the existing suspended smart rail car: 1. The track of t
