Abstract

T double-motor transmission for an engineering vehicle. The double-motor transmission for the engineering vehicle comprises an output shaft (2) and input shafts, first-gear input gears are installed on the two input shafts correspondingly, the two first-gear input gears and first-gear output gears (23) and are normally meshed, and the first-gear output gears (23) and second-gear output gears (5) are sleeved on the output shaft (2), the second-gear output gears (5) and the second-gear input gears installed on the input shafts are normally engaged, and the output shaft (2) is selectively connected with the first-gear output gears (23) or the second-gear output gears (5) through a gear shifting device. The scheme that a gearbox is combined with the two small-displacement motors is adopted, running power transmission and conversion are achieved, and the problems that a large-displacement motor is large in size, limited by the center height and the running passing capacity of the whole vehicle, difficult to arrange and the like are solved.

Description

technical field [0001] The invention relates to a transmission of an engineering vehicle, in particular to a transmission suitable for dual motors. Background technique [0002] The gearbox assembly of the existing excavator all adopts the combination of the gearbox and a single large-displacement motor to realize the transmission and transformation of the driving force of the whole vehicle. Due to the large volume of the large-displacement motor, it is difficult to arrange it due to the limitation of the center height and the driving capacity of the whole vehicle. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dual-motor-driven transmission structure for the problem of difficulty in arranging a single large-displacement motor. [0004] Technical scheme of the present invention is: [0005] A dual-motor transmission for engineering vehicles, including an output shaft and an input shaft, one input gear is ins...
