Electric transmission bogie for track engineering vehicle

Abstract

The invention discloses an electric transmission bogie for a track engineering vehicle, comprising a frame, a shaft box device, wheel pairs, a basic braking device, a suspension device, power transmission devices, a traction device and a bearing device, wherein the shaft box device is arranged between the wheel pair and the frame; the basic braking device is arranged at a position on the frame, close to the wheel pair; the suspension device is arranged between the frame and the shaft box device; the power transmission devices are obliquely and symmetrically distributed at the two edge sides of the bogie; each power transmission device comprises a traction motor, a gear box and an elastic coupler; the two edge sides of the bogie are respectively provided with a traction motor; each wheel pair is provided with a speed reducing box; the tractor motor is connected with the gear box by the elastic coupler; and both the traction device and the bearing device are arranged on the frame. The electric transmission bogie solves the technical problems of low transmission efficiency, complex structure, large occupied space, easy environmental pollution, difficulty in maintenance and repair and difficulty in application to compact space at the lower parts of underframes of most road-maintaining machines in the prior art.

Description

technical field [0001] The invention relates to a bogie device applied in the field of railway engineering, in particular to a novel electric drive bogie applied to large rail engineering vehicles. Background technique [0002] Bogie-Most of the running parts of modern vehicles are in the form of bogies, and its main functions are: 1. Bear the weight of the parts above the frame; 2. Ensure the necessary adhesion; 3. Make the vehicle have good stability during operation and stability; 4. Ensure that the vehicle passes through the curve smoothly; 5. Generate the necessary braking force. [0003] At present, large-scale rail engineering vehicles are powered by internal combustion engines to the bogies through hydraulic, hydraulic or mechanical transmission. When hydraulic or hydraulic transmission is used, the efficiency is between 0.7 and 0.8, which is relatively low. At the same time, a large number of oil pipelines need to be installed. Poor sealing will cause environmental...
