Problems solved by technology
[0003] The invention provides a drive device for a rack vehicle, which is used to solve the problem that due to the characteristics of the gear and rack transmission, the meshing of the gear and the rack has a relatively strict requirement for the center distance, and the wheel set will gradually wear out as it is used. After the wheel set is worn out, it will cause the defect that the running gear cannot mesh normally. By connecting the adjustment components with the bushing and the support frame respectively, the problem of matching the height of the running gear and the wheel set after the wheel set is worn is solved, and the unsprung mass is reduced at the same time, which is convenient Adjust the relative position between the running gear and the wheel set

The invention provides a driving device of a rack rail vehicle, a bogie and the rack rail vehicle. The device comprises a power box and a supporting frame which are arranged at an interval; an axle is arranged between the power box and the supporting frame, and wheel pairs are arranged at the two ends of the axle. The axle sleeve is arranged outside the axle in a sleeving mode, penetrates through the supporting frame and is in running fit with the supporting frame. The walking gear is connected with the shaft sleeve in the supporting frame, and part of the walking gear extends out of the supporting frame in the radial direction of the shaft sleeve so as to be meshed with a rack arranged on the ground. The shaft sleeve is rotationally sleeved with the adjusting assembly, and the adjusting assembly is connected with the supporting frame so that the relative position between the walking gear and the wheel pair can be adjusted. According to the driving device of the rack rail vehicle, the bogie and the rack rail vehicle, the adjusting assembly is connected with the shaft sleeve and the supporting frame, the height matching problem of a walking gear and a wheel pair after the wheel pair is abraded is solved, meanwhile, the unsprung mass is reduced, and the relative position between the walking gear and the wheel pair is convenient to adjust.
Description
technical field [0001] The invention relates to the technical field of rack vehicles, in particular to a drive device, a bogie and a rack vehicle of a rack vehicle. Background technique [0002] With the continuous development of the economy, the market demand for rack vehicles used in mountainous and hilly areas is becoming more and more extensive. In order to obtain greater climbing ability, the vehicle is driven by gears and racks. In order to solve the problem of motor power output, the torque power of the running gear is independently output by the bushing method, and the weight of the vehicle continues to be borne by the axle. However, due to the characteristics of gear and rack transmission, the meshing of gear and rack has strict center distance requirements, and the wheelset will gradually wear out with use, and when it reaches a certain level, the running gear will not be able to mesh normally. SUMMARY OF THE INVENTION [0003] The invention provides a driving d...
