Problems solved by technology

As the two drives roll back and forth on the track, the drive wheel is constantly rubbed by the track. The heavier the load-bearing rail car, the more severe the wear of the drive wheel. In this way, the gap between the left and right travel wheels gradually becomes larger over time, and the two drive wheels It cannot be tightly pressed on the track, and the driving wheel is used as a power wheel. If the friction with the track is not enough, it cannot effectively transmit power and drive the rail car. It is urgent to improve the above defects

Abstract

The invention discloses a self-adaptive pressing device of a railway car, comprising a walking frame arranged on a vertical rail and walking along the vertical rail, wherein a first sliding frame is located on one side of the vertical rail on the walking frame and can move relative to the walking frame by a translation mechanism; a first driving wheel capable of pressing one side wall of the vertical rail is arranged on the first sliding frame; a second driving wheel capable of pressing the other side wall of the vertical rail is arranged on the walking frame; a driving device for driving the first driving wheel or / and the second driving wheel to rotate is arranged on the first sliding frame or / and the walking frame; a first connecting rod driving mechanism is also arranged on the walking frame; after the first connecting rod driving mechanism is suffered from the gravity, the first driving wheel tightly presses one side wall of the vertical rail, therefore, the left driving wheel and the right driving wheel tightly presses on the left side and the right side of the rail; and the larger the load of the first connecting rod driving mechanism is, the higher the pressure of the driving wheel on the rail is, so that an automatic regulation function is achieved.

Description

[technical field] [0001] The invention relates to an adaptive pressing device for a rail car. [Background technique] [0002] The current rail car is provided with a walking frame, on which the left and right driving wheels are fixed, and the relative positions of the left and right driving wheels are constant, and there is a gap for the rail to pass between the left and right driving wheels. The left and right driving wheels of the rail car are respectively pressed on the track. As the two drives roll back and forth on the track, the drive wheel is constantly rubbed by the track. The heavier the load-bearing rail car, the more severe the wear of the drive wheel. In this way, the gap between the left and right travel wheels gradually becomes larger over time, and the two drive wheels It cannot be pressed tightly on the track, and the driving wheel is used as a power wheel. If the friction with the track is not enough, it cannot effectively transmit power and drive the rail ...
