Technical Field

The invention belongs to the technical field of highway and railway dual-purpose traction locomotives, and particularly relates to a double-swing-frame balancing device of a highway and railway dual-purpose traction locomotive.

Background

The traveling support mechanism of the domestic track tractor generally adopts a bogie structure, the bogie directly bears the dead weight and the load of a vehicle body, the vehicle is guided to run along a track, and the vehicle body can rotate for a certain angle in the horizontal plane relatively, so that the vehicle can turn smoothly, and the buffering vibration damper is arranged, so that the vibration impact generated when the vehicle runs can be relieved, and the track unevenness at two sides can be adapted. But the bogie has complex structure, large volume and high cost, and is not suitable for a low-speed rail traction device.

Tractor is transported with heavy load to road, including frame and suspension, the engine is connected with the gearbox, installs on the frame, suspension install in the bottom of frame, the frame above install the saddle of connecting the semitrailer, be provided with V-arrangement structure suspension at the frame rear portion, V-arrangement structure suspension include the transaxle that sets up side by side around two sets of, set up a balance shaft between two transaxles, spring steel plate group is installed at the both ends of balance shaft, spring steel plate group's both ends and two transaxle overlap joints, balance shaft and connected to the frame are connected with down the dowel bar between the both ends of balance shaft and two transaxles respectively. However, the V-shaped suspension system also has the problems of complex structure and poor maneuverability.
