Electric locomotive and city rail vehicle single-motor drive double-shaft way and bogie thereof

Abstract

Disclosed is a monomotor-driven double-shaft steering bogie for power cars and urban rail vehicles, comprising a truss, a brake shoe, a brake disc, an oscillating damper, wheels, wheel-countershafts, a drive motor, a shaft join, gear cases and a secondary spring. The invention is characterized in that the steering bogie has two shafts and is driven only by one motor, that means one motor drives the two shafts of the steering bogie synchronously. The drive motor is arranged at the middle part of the steering bogie and two gear cases are disposed at the two sides of the drive motor; two ends of the shaft of the drive motor are respectively connected with the two wheel-countershafts through the gears in the two gear cases; the drive motor is mounted on the beam of the truss and the shaft of the motor is parallel to the wheel-countershafts. The shaft of the motor is connected with the shafts of the drive gears in the gear cases; gear clusters are arranged inside the gear cases to shift gears. One gear cluster consists of a drive gear, an idle gear and a gearwheel; the gearwheels are fixed with the wheel-countershafts through interference fit and the wheel-countershafts are fixed with the wheels through interference fit. When the drive motor is galvanized, the shaft of the motor drives the drive gears to rotate and the drive gears drive the gearwheels to rotate through the idle gears; the interference fits between the gearwheels and the wheel-countershafts, and the interference fits between the wheel-countershafts and the wheels make the wheels to rotate, then the vehicle starts to move.

Description

technical field [0001] The invention relates to a component device structure of an electric locomotive for rail transit and an urban rail vehicle, specifically a bogie for an electric locomotive and an urban rail vehicle driven by a single motor with two axles for an electric locomotive for rail transit and an urban rail vehicle. The utility model is used in bogies of various electric locomotives and urban rail vehicles, and belongs to the field of railway rolling stock. Background technique [0002] The main functions of electric locomotive and urban rail vehicle bogies are to bear the weight of the car body, transmit traction and braking force, withstand wheel-rail vibration and impact, and ensure that the rolling stock passes through the curve smoothly. The structure of the bogie will affect these properties. Most of the drive systems of the existing international and domestic electric locomotives and subway car bogies use a single motor to drive a single shaft. The mai...

AI Technical Summary

Problems solved by technology

Conventional bogies use one motor to drive one wheel set. A 2-axis bogie needs to install two motors (the motor is located between the two wheel set axles), plus a beam between the motors, resulting in the distance between the two axles Bigger, not conducive to the bogie through the curve
