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

Embodiment Construction

[0027] See figure 1 As shown, an adaptive pressing device for a rail car includes a walking frame 2 arranged on a vertical rail 1 and walking along it. On the side of the vertical rail 1 on the walking frame 2, a passing translation mechanism is provided. 21 The first sliding frame 3 that moves relative to the walking frame 2 is provided with a first driving wheel 5 that can be pressed against a side wall of the vertical rail 1 on the first sliding frame 3, and the walking frame 2 is provided with a To the second driving wheel 6 on the other side wall of the rail 1, a driving device 7 for driving the first driving wheel 5 or / and the second driving wheel 6 to rotate is provided on the first sliding frame 3 or / and the walking frame 2. The walking frame 2 is also provided with a first link driving mechanism 8 which includes a first load-bearing rod 80 for bearing the weight of the load-bearing cabin, and one end of the first load-bearing rod 80 is hinged with a first connecting rod...

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 of a rail car. [Background technique] [0002] The current rail car is equipped with a walking frame. The left and right driving wheels are fixed on the walking frame. The relative position of the left and right driving wheels is unchanged. There is a gap between the left and right driving wheels for the track to pass through. The left and right drive wheels of the railcar are respectively pressed on the track. As the two drives roll back and forth on the track, the drive wheels are constantly rubbed by the track. The heavier the railcar is, the more the drive wheels will wear out. As a result, the gap between the left and right travel wheels will gradually increase over time. It cannot be pressed tightly on the track. The driving wheel is used as the power wheel. If the friction with the track is not enough, it will not be able to effectively transmit power and drive the rail car to drive. The above-m...
