Problems solved by technology

Most of the existing motor gearboxes use a single input source and a single output end, resulting in power interruption when shifting gears. The route of the mining vehicle is single, but the road conditions are bad, and most of the time it is in the stage of full load climbing, which is also frequent In this stage, if the power is interrupted when shifting gears on a steep slope, it will easily cause great psychological pressure on the driver and cause potential accidents.

Embodiment approach

[0033] According to a preferred embodiment of the present invention, see figure 1 , providing a dual-motor electric drive axle structure, characterized in that it includes:

[0034] The first input shaft 18 is connected to the first motor M1;

[0035] The first gear 1 and the second gear 6 are relatively rotatably sleeved on the first input shaft 18;

[0036] The sliding sleeve 3 is slidably connected to the first input shaft in a manner of synchronous rotation with the first input shaft and can move and switch between the first position, the middle position and the second position. The sliding sleeve 3 When positioned at the first position, the first gear 1 and the first input shaft 18 are locked to transmit the power of the first motor to the first gear through the first input shaft, and when the sliding sleeve 3 is positioned at the second position, the second gear is locked 6 and the first input shaft 18 to transmit the power of the first motor to the second gear via the...

Abstract

The invention provides a double-motor electric drive axle structure which comprises a first input shaft connected with a first motor; a first gear and a second gear; a sliding sleeve; a first parallel shaft; third to fifth gears; an intermediate shaft; a planet row; a second input shaft connected with a second motor; a second parallel shaft parallel to the second input shaft; a seventh gear and an eighth gear; and a differential. The system is compact in structure, the arrangement space is saved, and it can be guaranteed that power of the vehicle is not interrupted when climbing.

Description

technical field [0001] The invention relates to the field of machinery and vehicle transmission, in particular to a dual-motor electric drive axle structure. Background technique [0002] my country is rich in mineral resources, and the demand for mineral resources is also huge. As the main tool for mining mineral resources - mining vehicles, more and more attention has been paid to them. At present, most mining vehicles are powered by fuel-type engines and gearboxes. However, there are relatively few mining vehicles using electric motors as the power source. With the upgrading of my country's energy sources, electric drive mining vehicles are gradually being valued. Most of the existing motor gearboxes use a single input source and a single output end, resulting in power interruption when shifting gears. The route of the mining vehicle is single, but the road conditions are bad, and most of the time it is in the stage of full load climbing, which is also frequent In this st...
