Elastic vibration reduction towing mechanism of track vehicle

Abstract

Provided is a damping traction device of car elasticity for track locomotives. A left turn arm and a right turn arm are connected by an elastic connector the composition of which is that the left end portion of a left connecting rod is hinged with the left turn arm, the right portion of the left connecting rod is sleeved by a spring guide tube which is provided with a spring chamber, the right end of the spring guide tube is connected with a right connecting rod, and the right end of the right connecting rod is hinged with the right turn arm, a left limit boss and a right limit boss are respectively arranged at the two ends of the spring chamber which is disposed on the right portion of the left connecting rod and is corresponding to the spring guide tube,, the inner side of the spring guide tube is provided with a boss moving chamber which is matched with the left limit boss and the right limit boss, the inner sides of the left limit boss and the right limit boss of the left connecting rod are correspondingly provided with a left sliding block and a right siding block, and the positions of the spring chamber positioned in the left sliding block and the right siding block are provided with preloaded buffer springs. The traction device can effectively absorb and decrease the vertical impact force of the locomotives, increase the safety of locomotive running and the stability of vertical traction, and prolong the service life of the device and the connecting positions. The existing rigid six-bar traction mechanism can be conveniently employed as a basis for transformation, thereby the costs is saved.

Description

technical field [0001] The invention relates to a traction device for a railway locomotive, in particular to a six-bar traction device for a railway locomotive. Background technique [0002] The six-bar traction device is widely used in my country's Dongfeng and Shaoshan series passenger and freight locomotives, such as the main locomotives DF4, DF8, DF11, SS3, and SS9 currently used in railway transportation. It is a six-bar mechanism, the rear ends of the left and right drawbars are connected with the car body, the front ends of the left and right drawbars are respectively hinged to the left and right crank arms, and the other ends of the left and right drawbars are respectively connected to the cross bar. Both ends are hinged; at the same time, the corners of the left and right crank arms are connected to the bogie through the crank pins. The drawbar of the six-bar mechanism is located on both sides of the bogie, which is beneficial to the arrangement of other structures...

AI Technical Summary

Problems solved by technology

When the locomotive starts, brakes, and runs longitudinally and vibrates, the connection between the six-bar traction device, the bogie and the car body, and the rods of the traction device all bear a large longitudinal impact load, which reduces the traction device. The safety and service life of related components affect the stability of the longitudinal traction of the locomotive, and to a certain extent affect the wheel-rail adhesion state of the driving wheels
