Toothed rail and adhesion coaxial driving toothed rail driving device and toothed rail rolling stock

Abstract

The invention discloses a toothed rail and adhesion coaxial driving toothed rail driving device and a toothed rail rolling stock. A driven gearwheel is mounted on an axle through a bearing; a gear shaft (83) and a toothed rail side shaft sleeve (84) are mounted on the axle on one side of the driven gearwheel through bearings; an adhesive side shaft sleeve (85) is installed on the axle on the otherside of the driven gearwheel in an interference mode, the gear shaft and the toothed rail side shaft sleeve are rigidly and fixedly connected into a whole body, and the driven gearwheel is connectedwith the toothed rail side shaft sleeve or the adhesive side shaft sleeve through a clutch; an eccentric mechanism (52) with a self-positioning and self-locking mechanism is mounted on the gear shaftthrough the bearing, a window is formed in the eccentric mechanism, and outer teeth of the gear shaft are exposed out of the window; and a toothed rail wheel (51) is installed on the eccentric mechanism through the bearing, and the toothed rail wheel is internally meshed with outer teeth of the gear shaft. A height of the toothed rail wheel can be adjusted, and different reduction ratios can be provided for toothed rail driving and adhesion driving.

Description

technical field [0001] The invention relates to a driving device for a rail transit locomotive vehicle bogie, in particular to a rack driving device coaxially driven by cogs and adhesives and a rack locomotive. Background technique [0002] There are two types of existing rack drive devices in terms of function. One is the drive device with pure rack drive function, which only has rack drive and no adhesive drive function. Other drives are required for adhesive lines without rack. The device is used as the power to drive the cog train; the other is the coaxial driving device of cog rail and adhesion, which has the function of both rack drive and adhesion drive, and can be used on the cog-less adhesion line and the cog line. It can provide the driving force to realize the driving of the rack train. Whether the height of the rack wheel of the rack drive device is adjustable is divided into two types, that is, the height of the rack wheel is adjustable and non-adjustable. The...

AI Technical Summary

Problems solved by technology

Although this rack drive device realizes the conversion of rack drive and adhesive drive only through a set of power transmission devices, due to the non-adjustable height of the rack wheel and the wear of the wheels and rails, after a period of operation, the rack There will be a gap between the rack wheel and the rack wheel, which will damage the meshing performance of the rack wheel and the rack wheel, and the rack drive cannot be efficiently driven

[0004] Chinese patent CN109532888A discloses a rack wheel height adjustment mechanism and a rack wheel drive device. Although it is an impure rack drive device, its adhesive wheel pair is separated from the drive device and only plays a supporting and guiding role. Therefore, it is not a rack and adhesive coaxial drive device
