Embodiment 1

[0035] A dual-motor gearbox includes a first output shaft c, a second output shaft e, a first motor M1 and a second motor M2. Wherein, the first motor M1 includes a first input shaft a, the first input shaft a is connected with the first output shaft c through a first transmission mechanism, and is used to drive the first output shaft c to rotate; the second motor M2 includes a second input shaft d, the second input shaft d is connected with the second output shaft e through the second transmission mechanism, and is used to drive the second output shaft e to rotate; the second input shaft d is a hollow shaft, and the second input shaft d is movably sleeved on the first input shaft on axis a.

[0036] Utilizing the technical solution of the present invention, the second input shaft d of the second motor M2 is set as a hollow shaft, which is movably fitted on the first input shaft a of the first motor M1, and the two motors are integrated into one, compact in structure, small in...

Embodiment 2

[0055] The difference between this embodiment and embodiment 1 is that the shift mechanism includes a first clutch 8 and a second clutch 9, refer to Figure 4 , one end of the first clutch 8 is fixed, and the other end is connected with the first ring gear 3; one end of the second clutch 9 is connected with the planet carrier 4, and the other end is connected with the sun gear 1. In this embodiment, the second clutch 9 is connected with the sun gear 1 through the intermediate shaft b, Figure 4 in neutral state.

[0056] refer to Figure 5 , wherein the first clutch 8 is in the engaged state, and the second clutch 9 is in the disengaged state. At this time, the first ring gear 3 is locked, and the sun gear 1 drives the planetary gear 2 to rotate, thereby driving the planetary gear carrier 4 to rotate. At this time, the output speed is the first gear speed, and the order of power transmission is: first input shaft a, first driving wheel 101, first driven wheel 102, intermedi...

Embodiment 3

[0060] A construction machine includes the dual-motor gearbox described in any one of the above embodiments.

[0061] Specifically, the construction machine is a loader. Wherein, the first motor M1 is a traveling motor, which drives the loader to travel in two gears and two speeds or reverse in one gear. The second motor M2 is an operating motor, which drives the steering, lifting and lubrication of the loader.

[0062] According to the above description, the patent application has the following advantages:

[0063] 1. The dual motors are integrated into one body, the structure is compact, and the space occupied is small, which is conducive to the layout and maintenance of the whole vehicle.

[0064] 2. The transmission structure of a single planetary row is adopted, and a synchronizer is used to realize the switching of two gears, with a small number of parts and a simple structure;

[0065] 3. The number of gear pairs for transmission between the first input shaft a and t...

Abstract

The invention provides a double-motor gearbox and engineering machinery, and relates to the technical field of engineering machinery, and the double-motor gearbox comprises a first output shaft, a second output shaft, a first motor and a second motor. The first motor comprises a first input shaft, and the first input shaft is connected with the first output shaft through a first transmission mechanism; the second motor comprises a second input shaft, and the second input shaft is connected with the second output shaft through a second transmission mechanism; the second input shaft is a hollow shaft, and the first input shaft is movably sleeved with the second input shaft. The problems that in the prior art, two motors are independently placed, so that the structure is scattered, the compactness is low, the occupied space is large, and arrangement and maintenance of the whole machine are not facilitated can be solved, the double motors are integrated, and the motor has the advantages of being compact in structure, small in occupied space and beneficial to arrangement and maintenance of the whole machine.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a dual-motor gearbox and construction machinery. Background technique [0002] At present, the existing gearboxes in the market, taking the electric loader as an example, have a dual-motor drive mode, one motor drives the hydraulic pump of the working device, and the other motor drives the walking, but the two motors in the prior art are placed independently. Scattered structure, low compactness, large space occupation, not conducive to the layout of the whole machine, and brings difficulties to maintenance. Contents of the invention [0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects of scattered structure, low compactness, large space occupation, and unfavorable layout and maintenance of the whole machine brought about by the independent placement of two motors in the prior art, thereby providing a Dual-mo...
