Driving device of alternating-current transmission rail traction locomotive

Abstract

The invention provides a driving device of an alternating-current transmission rail traction locomotive. The device comprises a speed reducer, a wheel set, two axle boxes and two axle box springs, wherein the wheel set comprises an axle and two wheels with which the axle is sleeved; an output shaft of the speed reducer and the axle are in transmission connection; the axle boxes are arranged at the end parts of the axle and are in transmission connection with the axle; one end of each axle box spring prop against the shaft box, and the other end of each axle box spring is fixed on a steering frame; the axle box springs are V-shaped rubber springs. According to the driving device provided by the invention, the steering frame is connected with the axle boxes of a walking part through the V-shaped rubber springs, and when the route of the locomotive is poor, the V-shaped rubber springs bear acting forces and damping effects in a vertical direction, a transverse direction and a longitudinal direction, so that the vibration of the locomotive is alleviated, the impact among wheel rails is reduced, the comfort and the reliability of locomotive operation can be improved, the maintenance amount is reduced, the abrasion of the wheel rails can be effectively reduced, and the driving comfort of the locomotive is improved.

Description

technical field [0001] The invention relates to rail transit technology, in particular to a driving device for rail AC drive traction locomotives. Background technique [0002] The driving device of the electric transmission traction locomotive uses a traction motor with high speed and low torque to drive the power axle with large resistance. [0003] The industrial and mining vehicles used in coal mines and metal mines are electric locomotives with a viscosity of less than 25 tons. This type of electric locomotive is usually driven by a DC motor, and the wheel set is driven by a reduction box to achieve traction. The weight of the locomotive above the bogie frame is transmitted through the axle box spring. For the axle box, the axle box spring is arranged between the axle box and the bogie frame, and a leaf spring is usually used as a shock absorbing device. Due to the shortcomings of the leaf spring damping device itself, the running stability and comfort of the locomotiv...

AI Technical Summary

Problems solved by technology

Due to the shortcomings of the leaf spring damping device itself, the running stability and comfort of the locomotive are poor. In addition, the leaf spring is easy to break and difficult to disassemble and replace. The most critical thing is that the process of leaf spring absorbing energy and damping vibration is through the friction between the steel plate groups. Realized, so the leaf spring group wears a lot, has a short life, and needs regular maintenance; at present, for electric locomotives with a viscosity of 14 tons to 25 tons, more than two types of driving devices are usually used, and the ones are often selected due to different gauges. The specifications of the driving devices are also different, so there are many types of parts and components, and they are not universal, and the cost of use and maintenance is high
