Problems solved by technology

The complexity of the structure leads to the process complexity and production cost of the driving wheel system increase, and the reliability and maintainability decrease
In addition, due to the processing of arc-shaped rails, special pressure forming equipment and production personnel are required, which further increases production costs

Embodiment Construction

[0015] figure 1 Among them, the multi-segment driving rods 2 are connected by joints 8 and move along the direction defined by the track 1 . There is positive pressure exerted on the driving rod 2 between the supporting wheel 4 and the driving wheel 5, and the driving wheel 5 rotates, thereby generating driving force. The track is at a turn, and is fitted by a straight line segment, thereby forming a straight line fitting segment 7 of the turn track. The straight-line fitting section 7 of a turning track where the driving wheel is installed should meet the following requirements: the length of every two driving sub-rods is less than the length of the straight-line fitting section 7 of the turning track, and the driving point generated by the joint action of the driving wheel and the supporting wheel 6 is at the midpoint of the straight line fitting section 7 of this section of the turning track. Thereby make the driving rod that enters the middle point of the straight line f...

Abstract

A railcar bend non-swing drive wheel system belongs to the technical field of rail logistics and consists of a rail (1), a drive rod (2) and a drive wheel system; wherein, the drive rod (2) is integrated with the body of the railcar as a part of the body of the railcar; the drive wheel system includes a motor, a drive wheel (5) connected with the motor and a riding wheel (4) matched with the drive wheel; when the drive rod (2) enters the drive wheel system, the drive wheel and the riding wheel generate a positive pressure under the effect of a pre-tightening force; a friction force for driving is instantly generated when the motor drives the drive wheel to rotate; the railcar bend non-swing drive wheel system is characterized in that the drive rod consists of n sections of drive sub-rods; besides, the neighboring drive sub-rods are connected by a rotating pair; the swerve location of the rail consists of m sections of linear fitting sections of the swerve rail. The railcar bend non-swing drive wheel system reduces the complexity of the drive wheel system, thereby improving the reliability of the drive wheel system and effectively reduces the maintenance cost.

Description

Technical field [0001] The invention relates to a non-oscillating drive wheel system for a rail car on a curved road, and belongs to the technical field of rail logistics. Background technique [0002] At present, the known friction-driven track logistics system is composed of a track, a drive rod and a drive wheel system, and the drive rod is a part of the car body. The driving wheel system is composed of the driving wheel connected with the motor, the supporting wheel used in conjunction with the driving wheel, a series of spring systems and rotating pairs. When the driving rod integrated with the car body enters the driving wheel system, the driving wheel and supporting wheel will generate positive pressure under the preload of the spring system. When the motor drives the driving wheel to rotate, it will generate frictional force for driving. However, since the arc-shaped track is adopted at the turning point, and the drive rod is a longer straight rod, the drive rod bec...
