Description

Technical Field

[0001] This utility model relates to the field of power transmission technology for engineering machinery, and in particular to a dual-motor input electric drive box for loaders. Background Technology

[0002] With the rapid development of the construction machinery industry, the efficiency, reliability, and environmental performance of the power transmission system of loaders, as one of the main construction machinery equipment, are receiving increasing attention. Traditional loader power transmission systems primarily rely on an internal combustion engine to provide power, which is then transmitted to the gearbox via a torque converter, and finally drives the walking system and working device. This traditional transmission method prevents independent output for operation and travel, resulting in inconsistent oil pump flow and low efficiency of the oil pump and power take-off point. This limits the loader's flexibility and efficiency under different working conditions, and also presents problems such as complex structure, low transmission efficiency, and low energy utilization.

[0003] Currently, various improved transmission devices exist in the field of construction machinery. For example, patent application CN 116518036 A discloses a dual-motor driven gearbox assembly for construction machinery. This gearbox, by employing dual-motor drive, allows the walking system and hydraulic working system to operate independently. It has two power take-off ports: one for the gearbox oil pump and one for the working device, and its layout is reasonable and maintenance is convenient. However, this gearbox is relatively large, has low transmission efficiency, and its reliability is generally poor.

[0004] Therefore, there is an urgent need for a new type of dual-motor input electric drive box that can achieve independent output for operation and travel, has a compact structure, improves gearbox transmission efficiency, and meets the special needs of electric engineering machinery.

The front and middle parts of the input shaft 16 are supported on the second housing component II by bearings. An input flange 14 is arranged at the front end of the input shaft 16.

The second driven gear 15 is set on the input shaft 16 by a spline. The first input gear 13 and the second driven gear 15 mesh.

[0046] like Figure 1 , Figure 3 and Figure 6As shown, planetary gear set component V includes a planetary shaft 25, a planetary carrier 26, a first gear ring 27, planetary gears 30, and a first clutch. The planetary gears 30 are rotatably mounted on the planetary carrier 26 via the planetary shaft 25 and mesh with the first gear ring 27.

The direct drive cylinder 35 is fixedly connected to the second housing component II. The second clutch is disposed inside the direct drive cylinder 35. A second piston 37 and a second spring 38 for resetting the second piston 37 are provided on one side of the second clutch.

In order to make the second clutch disengage more completely, the second spring 38 is a disc spring.

[0048] like Figure 1 , Figure 3 and Figure 8 As shown, the output component VII includes an output shaft 45 and an output gear 44 connected to the output shaft 45 via a spline; the front end and the rear end of the output shaft 45 both extend outward from the housing component, the front end of the output shaft 45 is provided with a front output flange 39, the rear end of the output shaft 45 is provided with a rear output flange 46, and the output gear 44 meshes with the pressure plate gear 36.

[0049] like Figure 1 , Figure 5 , Figure 9 and Figure 10 As shown, the second input component IV is used for power input to the hydraulic motor. The second input component IV is also connected to the power take-off and oil pump component VIII and the power take-off component IX via gear transmission. Using a hydraulic motor as the power source for the oil pump, the pump draws and circulates oil within the electric drive unit, thereby ensuring stable operation of the oil pump and meeting the requirements of low energy consumption and environmental protection.

[0050] Specifically, the second input component IV includes a third input gear 20, a first driven gear 21, a PTO shaft 22, and a PTO drive gear 23. The third input gear 20 is connected to the hydraulic motor via a spline, and both ends of the third input gear 20 are supported on the housing by bearings.

The solenoid valve M1 is used to control the engagement and disengagement of the first clutch, and the solenoid valve M2 is used to control the engagement and disengagement of the second clutch.

[0052] The drive box is designed to control the work output and travel output separately by using dual motor inputs. By replacing the intermediate shaft gear transmission structure in the existing technology with a planetary gear set component V, the overall structure of the drive box is more compact and has higher transmission efficiency and greater torque transmission capacity.

[0053] In this dual-motor input electric drive box, the forward and reverse movement of the dual-motor input electric drive box is controlled by the forward and reverse rotation of the hydraulic motor and the travel motor. The engagement and disengagement of the first clutch and the second clutch in the electric drive box are controlled by the operation and control components, thereby controlling the switching between high speed and low speed.

[0054] The process of switching between high and low gears:

[0055] When the solenoid valve M1 (low speed gear) is engaged, the travel motor inputs power to the first input shaft 16 through the first input gear 13 and the second driven gear 15. The first input shaft 16 drives the planetary gear 30 to rotate. The planetary gear 30 meshes with the first gear ring 27. Pressurized oil enters the first gear cylinder 5, thereby pushing the first piston 12 to press the first inner friction plate 28 and the first outer friction plate 29. The first clutch engages, fixing the first gear ring 27, thereby transmitting power to the planetary carrier 26. The planetary carrier 26 is connected to the pressure plate gear 36. The pressure plate gear 36 meshes with the output gear 44. The output gear 44 drives the output shaft 45 to rotate, thereby outputting power.

[0056] When solenoid valve M2 (high speed gear) is engaged, the travel motor inputs power to the first input shaft 16 through the first input gear 13 and the second driven gear 15. The first input shaft 16 drives the second gear ring 32 to rotate, and pressurized oil enters the direct drive cylinder 35, thereby pushing the second piston 37 to press the second inner friction plate 33 and the second outer friction plate 34. The second clutch is engaged, thereby rotating the pressure plate gear 36. The pressure plate gear 36 meshes with the output gear 44, and the output gear 44 drives the output shaft 45 to rotate, thereby outputting power.

[0057] All features described in the specification, appended claims and drawings, whether individually or in any combination thereof, are essential features of this utility model.

[0058] In this specification, the illustrative expressions of the terms used do not necessarily refer to the same embodiments or examples.
