Abstract

The invention discloses a driver controller for the traction system of an EMU, which includes a driving gear, a limiting plate, and a handle. A limiting rod is fixed on the driving gear. The upper part of the stop rod is sleeved in the cavity and the two are connected by a spring. The connector is provided with a limit slot along the length of the handle. The limit screw is fixed in the area of ​​the limit slot on the limit rod. The connector is along the vertical direction. A roller shaft is fixed in the direction of the handle, a rolling bearing is sheathed on the roller shaft, and a side roller is respectively sheathed on the rolling bearing at the positions on both sides of the limiting plate. In the traction system of an EMU according to the present invention, the driver controller adds side rollers on both sides of the rolling bearing to slide with the limit plate in an orbital manner, and uses the cooperation between the two sides of the side rollers and the two sides of the limit plate to eliminate the original torsion The shear stress ensures the operational reliability of the LC handle assembly, thereby improving the reliability of the driver's controller.

Description

technical field [0001] The invention belongs to the technical field of locomotive equipment, and in particular relates to a driver controller for the traction system of an EMU. Background technique [0002] The driver controller is mainly used in the traction controller of the EMU. The driver of the locomotive completes the control functions such as the traction and braking functions of the EMU through the cooperation of the handle and the limit plate. However, the existing driver controller is used During the process, the fixing screw often breaks. For example, the CRH5 driver controller in my country is mainly used in the traction controller of the CRH5 standard EMU. Because the handle assembly of this kind of driver controller is along the limit plate When the outer contour rotates, the limit plate will produce resistance to the rolling bearing installed on the roller shaft in the handle assembly to make the handle assembly rotate, and the rotation will generate torsional s...
