Problems solved by technology
This kind of transmission system is easy to operate, and the performance of the mechanism is reliable during normal operation. When one of the motors is damaged, the other motor can continue to run; , or when the speeds of the two independent motors are inconsistent, the independent traction mode of the dual motors cannot balance the output torque of the motors, resulting in a decrease in the utilization rate of the electric locomotive, a decrease in the traction force, and a decrease in the carrying capacity of the electric locomotive; and the traditional dual-motor mining motor The locomotives are relatively large in structure, and the process of transporting electric locomotives above 8 tons to the underground through the shaft is relatively difficult.

The invention discloses a traction electric locomotive transmission device. The traction electric locomotive transmission device comprises a front wheel set (1), a rear wheel set (7), a front wheel reducer (2), a rear wheel reducer (6) and a traction motor (4). The front wheel reducer (2) is connected with the front wheel set (1), and the rear wheel reducer (6) is connected with the rear wheel set(7). The traction motor (4) is arranged between the front wheel reducer (2) and the rear wheel reducer (6). A front end output shaft of the traction motor (4) is connected with the front wheel reducer (2) through a front wheel coupler (3). A rear end output shaft of the traction motor (4) is connected with the rear wheel reducer (6) through a rear wheel coupler (5). The traction electric locomotive transmission device is compact in structure, an electric locomotive structure of the same type is smaller in size, and work is reliable; the traction capacity of the mining electric locomotive canbe fully exerted, the carrying capacity of the mining electric locomotive is improved, the production efficiency can be improved, and potential safety hazards are reduced.
Description
technical field [0001] The invention relates to a mining electric locomotive, in particular to a traction electric locomotive transmission device, which belongs to the technical field of mine transportation equipment. Background technique [0002] The development trend of mining electric locomotives is high-speed and heavy-duty traction, so the locomotive needs to have a large shaft power. Due to the limitation of line conditions, the number of axles and axle load of a single locomotive have a certain range of values. With the locomotive power Increasingly, the ratio of locomotive weight to power is getting smaller and smaller, which requires making full use of the locomotive's adhesive weight to exert greater axle traction and prevent the wheel from idling. [0003] Underground mining electric locomotives mostly use two-axle mining electric locomotives, and most of the two-axle mining electric locomotives are driven by dual motors and double independent drive shafts, that i...
