Abstract

The invention relates to a synchronization control device for wheel pair speed of a locomotive fixation test bed, and is characterized in that the invention comprises six pairs of axles arranged oppositely, and a synchronization control system. Each three pairs are connected into a mechanical synchronizing system. Each of the mechanical synchronizing systems is connected with a transmission system. The two transmission systems are connected with a dynamometer, respectively. The two dynamometers are connected with a load, respectively. The synchronization control system comprises a master governor, a secondary controller, two excitation controllers and two exciter circuits, which are connected in turn. The exciter circuits are connected with the two dynamometers, respectively. The invention can regulate the velocity control and synchronization control of the wheel pairs automatically in the locomotive fixation test, and has the characteristics of excellent following feature and small errors.

Description

technical field [0001] The invention relates to a locomotive test device, in particular to a wheel set speed synchronous control device for controlling the speed of each wheel set of a locomotive in a traction test device. Background technique [0002] At present, my country's railways continue to speed up on a large scale. The increase in train speed has put forward higher requirements for the safety and reliability of locomotive operation. Therefore, it is very necessary to build a locomotive fixed test bench suitable for different structural characteristics and capable of starting test, traction test, braking test, etc. The speed control and speed synchronous control of each wheel set of the locomotive in the fixed test stand of the locomotive are the guarantee for the smooth progress of various traction tests of the locomotive on the fixed test stand. [0003] At present, there is no device to automatically control the synchronous rotation of each wheel pair in the loco...
