Driving guide mechanism of rail-road car

Abstract

The invention provides a driving guide mechanism of a road-rail car, and belongs to the technical field of road-rail cars. The problems that an existing road-rail car is single in driving force source, the railway traction capacity cannot be further improved, and power of a front rubber wheel is wasted are solved. According to the technical scheme, the mechanism comprises a guide steel wheel, a rotary support and a guide oil cylinder; one end of the guide oil cylinder is connected with the rotary support, and the other end of the guide oil cylinder is connected with a chassis of the rail-road car; the end, away from the guide oil cylinder, of the rotary support is hinged to the chassis, and a rotating shaft of the guide steel wheel is connected with the rotary support; a friction wheel is arranged on the first rotating shaft and used for being in contact with the front rubber wheel, and the first rotating shaft is connected with a rotating shaft of the guide steel wheel through a transmission device; the technical effects are as follows: the power of the front rubber wheel is reasonably utilized, the driving force source is enriched, the traction capability of a railway is improved, and the braking distance of the railway is shortened.

Description

technical field [0001] The invention belongs to the technical field of road-rail vehicles, in particular to a driving and guiding mechanism for road-rail vehicles. Background technique [0002] The existing road-rail vehicle can be divided into two types according to the driving mode, the rubber wheel drive and the steel wheel drive. The rubber wheel drive uses the drive system of the original chassis, the rear rubber wheel is used as the driving wheel, and the guide steel wheel is the passive wheel. The front rubber tire is lifted to idle. This type of public rail car is currently widely used in this field because of its low manufacturing and maintenance costs and strong power. However, the rear rubber tire is seriously worn, the load distribution is complicated, and it is easy to derail. And the power waste of the front rubber wheel, etc.; the steel wheel drive means that the rubber wheel is lifted and does not participate in the railway operation, and the guide steel whee...
