Problems solved by technology

Its disadvantages are: slow action response, low braking efficiency, and high labor intensity. Because the braking surface is the working surface of the wheel, it is easy to produce slippage during braking, and there are great safety hazards in the operation of electric locomotives, which may cause safety problems ACCIDENT

Abstract

The invention discloses a pulling electric locomotive, which comprises a locomotive body provided with a current collector. The front part and the back part of the body are provided with buffers; a driving device is arranged in the body and comprises a pulling motor which is coupled with a speed reduction driving device by a coupler; and the speed reduction driving device is a worm-gear speed reduction driving device. The electric locomotive has the following beneficial effects that: the worm-gear speed reduction driving device of the pulling electric locomotive belongs to the first class driving and has the characteristics of small volume, small noise and less and convenient maintenance compared with the traditional speed reduction device used in the whole running process of the locomotive. Simultaneously, a disc-typed brake device is adopted to control a worm to rotate so as to control the moving of the locomotive, thus fundamentally eliminating the potential safety hazard of brake failure caused by the environment, overcoming the abrasion to wheels when a brake-shoe brakes, improving the brake control efficiency and further improving the safety performance of the electric locomotive.

Description

technical field [0001] The invention relates to an electric locomotive. Background technique [0002] At present, the electric locomotive deceleration device belongs to the two-stage transmission, which has the characteristics of large size, high noise, large maintenance volume and high maintenance cost. During the braking operation, the brake screw is used to drive the lever mechanism by turning the hand wheel, so that the brake shoe will rub against the wheel and brake. Its disadvantages are: slow action response, low braking efficiency, and high labor intensity. Because the braking surface is the working surface of the wheel, it is easy to produce slippage during braking, and there are great safety hazards in the operation of electric locomotives, which may cause safety problems ACCIDENT. Contents of the invention [0003] The object of the present invention is to provide a traction electric locomotive. [0004] The purpose of the present invention is achieved in the...
