[0042] The utility model provides a kind of axle 100, which is suitable for vehicle, such as car, loader and the like. Specifically, please refer to Figures 1 to 3 In the embodiment, the axle 100 includes an axle body 1, a drive motor 2, a transmission 3, and a second output shaft 4. The axle body 1 includes an axle shaft 12 extending in a transverse direction. The drive motor 2 and the transmission 3 are arranged on two sides of the axle shaft 12 in a radial direction. The transmission 3 includes a first output shaft 31, which is in driving connection with the axle shaft 12. The second output shaft 4 connects the drive motor 2 and the transmission 3. The second output shaft 4 is parallel to the first output shaft 31. The first output shaft 31, the second output shaft 4, and the axle shaft 12 are arranged in a non-coplanar manner.

[0043] In the embodiment, the axle shaft 12 can be used to connect a wheel, and the rotation of the axle shaft 12 can drive the wheel to rotate. By distributing the drive motor 2 and the transmission 3 on two sides of the axle shaft 12, the overall center of gravity of the axle 100 can be better positioned at the center of the axle shaft 12, and the vehicle (such as the loader 1000) can be more stable during driving and less likely to shake. The first output shaft 31 of the transmission 3 is in driving connection with the axle shaft 12, so that the rotation of the first output shaft 31 can drive the axle shaft 12 to rotate, realizing the transmission of the torque of the drive motor 2. Moreover, the second output shaft 4 connecting the drive motor 2 and the transmission 3 is parallel to the first output shaft 31, so that the drive motor 2 and the transmission 3 can be better arranged on two sides of the axle shaft 12, and the structure is more compact. Moreover, the first output shaft 31, the second output shaft 4, and the axle shaft 12 are arranged in a non-coplanar manner, for example, the first output shaft 31 and the second output shaft 4 can be arranged in a staggered manner in the up-down direction, so that in terms of spatial arrangement, the drive motor 2 and the transmission 3 can be closer in the transverse direction, more compact, occupy less space, and better adapt to the installation of other components on the periphery, which is conducive to the optimization of the overall vehicle structure and simplifies the assembly operation.

[0044] Wherein, the above transverse direction can be any direction on the horizontal plane, when the axle 100 is applied to the loader 1000, the direction in which the loader 1000 advances is the front of the loader body 200, and the axle shaft 12 of the axle 100 is arranged along the left-right direction of the loader 1000. The description of the direction in the utility model can be used as a reference.

[0045] It should be noted that the first output shaft 31 and the second output shaft 4 can be substantially parallel. The projections of the first output shaft 31 and the second output shaft 4 on the plane where the axle shaft 12 is located can be arranged to intersect the axle shaft 12. Preferably, in combination with Figure 2 and Figure 4 As shown in the figure, the first output shaft 31 and the second output shaft 4 are perpendicular to the axle shaft 12, so that the first output shaft 31 and the second output shaft 4 are arranged shorter, the torque transmission loss is smaller, the driving torque of the driving motor 2 can be better transmitted to the axle shaft 12, thereby driving the wheels to rotate. Specifically, when the axle shaft 12 is arranged along the left-right direction, the first output shaft 31 and the second output shaft 4 are arranged to extend along the front-rear direction, that is, the transmission 3 and the driving motor 2 are located between the two wheels and are respectively located on the front and rear sides of the axle shaft 12, so that the transmission 3 and the driving motor 2 are not arranged side by side, thereby leaving more space between the wheels, which is convenient for the arrangement of other components.

[0046] It can be understood that the first output shaft 31 and the second output shaft 4 can be located on the same side of the axle shaft 12, for example, both located above the axle shaft 12; or the first output shaft 31 and the second output shaft 4 are respectively located on both sides of the axle shaft 12, for example, one of the first output shaft 31 and the second output shaft 4 is located above the axle shaft 12, and the other is located below the axle shaft 12. Preferably, the first output shaft 31 is coplanar with the axle shaft 12 and perpendicular, and the second output shaft 4 is located above the first output shaft 31, so that the position of the first output shaft 31 or the second output shaft 4 is lower than the position of the axle shaft 12, which does not affect the height of the vehicle chassis. Moreover, the driving force of the driving motor 2 is transmitted to the transmission 3 through the first output shaft 31, and the torque is converted through the transmission 3 and then transmitted to the axle shaft 12, which changes the direction of the torque and adjusts the size of the torque, thereby ensuring the efficient operation of the vehicle.

[0047] Moreover, the driving motor 2 and the transmission 3 are arranged on both sides of the axle shaft 12 in the longitudinal direction, that is, the driving motor 2 and the transmission 3 are arranged on both sides of the axle shaft 12 in the front-rear direction, and the driving motor 2 and the transmission 3 can be connected with the axle housing of the axle body 1, so that the overall center of gravity of the axle 100 can be better located at the center of the axle shaft 12, the center of gravity is more centered, and the vehicle is more stable during driving.

[0048] Preferably, in combination with Figure 4 andFigure 5 As shown, the driving motor 2 can be provided as a disc motor, which is smaller in size and lighter in weight, and has higher working efficiency due to its high rotating speed.

[0049] For the transmission 3, on one hand, it is used to adjust the driving torque, and on the other hand, it can change the driving direction. Preferably, the transmission 3 comprises a first transmission part provided on the first output shaft 31, the axle body 1 comprises a second transmission part coaxially connected with the axle shaft 12, and the first transmission part and the second transmission part are arranged in cooperation. When the driving motor 2 drives the second output shaft 4 to rotate, it drives the gear set in the transmission 3 to rotate, so that when the first output shaft 31 rotates, it drives the first transmission part to rotate, and under the cooperation of the first transmission part and the second transmission part, it drives the second transmission part to rotate, so as to drive the axle shaft 12 to rotate. Thus, through the cooperation of the first transmission part and the second transmission part, the rotating torque in the front-rear direction is converted into the rotating torque in the left-right direction, so that the structure is more compact, and the rotation of the wheel is better realized.

[0050] Among them, there are many ways to realize the conversion of the rotating torque of the first output shaft 31 into the rotating torque in the direction of the axle shaft 12. For example, it can be realized through mechanical transmission, through hydraulic or pneumatic transmission, or through electrical transmission. Corresponding to different transmission modes, the corresponding arrangement modes of the first transmission part and the second transmission part are also different.

[0051] Preferably, in combination with Figure 4 and Figure 5 As shown, the first transmission part comprises a first bevel gear 35 provided on the first output shaft 31, and the second transmission part comprises a second bevel gear 11 provided on the axle shaft 12, and the first bevel gear 35 and the second bevel gear 11 are arranged in engagement. Through the rotation of the first output shaft 31, the first bevel gear 35 is driven to rotate, and since the first bevel gear 35 is engaged with the second bevel gear 11, the second bevel gear 11 is driven to rotate, thereby driving the axle shaft 12 to rotate, so that the wheel can rotate together.

[0052] Moreover, the transmission 3 further comprises a one-gear set 32, a two-gear set 33, an output wheel set 34, and a gear shifting mechanism. The gear shifting mechanism is used to adjust one of the one-gear set 32 and the two-gear set 33 to cooperate with the output wheel set 34, so that when the one-gear set 32 rotates, it drives the output wheel set 34 to rotate, and the two-gear set 33 stops rotating, and when the two-gear set 33 rotates, it drives the output wheel set 34 to rotate, and the one-gear set 32 stops rotating. Moreover, the end gear of the output wheel set 34 is coaxially connected with the first bevel gear 35, so as to better adjust the rotating speed of the axle shaft 12.

[0053] Specifically, as Figure 5As shown in the figure, the first gear set 32 includes a first gear 321 coaxially arranged with the second output shaft 4, and a second gear 322 engaged with the first gear 321. The second gear set 33 includes a transmission shaft 331, and a third gear 332 and a fourth gear 333 engaged with each other. The third gear 332 is arranged on the second output shaft 4, and the second gear 322 and the fourth gear 333 are arranged on the transmission shaft 331. The output gear set 34 includes a first output gear 341 and a second output gear 342 engaged with each other. The first output gear 341 is arranged on the transmission shaft 331 and located between the second gear 322 and the fourth gear 333. The second output gear 342 is arranged coaxially with the first bevel gear 35 and is the terminal gear of the output gear set 34. The first gear 321 and the third gear 332 can move axially relative to the second output shaft 4, the second gear 322 and the fourth gear 333 can move axially relative to the transmission shaft 331, and the first output gear 341 is fixed on the transmission shaft 331. The gear shifting mechanism can be an electronic gear shifting mechanism. When the gear shifting mechanism is switched to the first gear, the first gear 321 can rotate together with the second output shaft 4, and the third gear 332 does not rotate together with the second output shaft 4. The second gear 322 is connected to the first output gear 341. When the second gear 322 is driven to rotate by the first gear 321, the first output gear 341 rotates together, so that the second output gear 342 rotates to drive the first output shaft 31 to rotate, so that the first bevel gear 35 rotates to drive the second bevel gear 11 to rotate, and then the axle 12 rotates to realize the rotation of the wheels.

[0054] Similarly, when the second gear is switched, the third gear 332 can rotate together with the second output shaft 4 by the gear shifting mechanism, and the first gear 321 does not rotate together with the second output shaft 4. The fourth gear 333 is connected to the first output gear 341. When the fourth gear 333 is driven to rotate by the third gear 332, the first output gear 341 rotates, so that the second output gear 342 rotates to drive the first output shaft 31 to rotate, so that the first bevel gear 35 rotates to drive the second bevel gear 11 to rotate, and then the axle 12 rotates to realize the rotation of the wheels.

[0055] Moreover, in combination with Figure 5 and Figure 6As shown, since the first output shaft 31 and the second output shaft 4 are arranged at different heights, when the first gear 321 and the second gear 322 are engaged, the third gear 332 and the fourth gear 333 are engaged, and the first output gear 341 and the second output gear 342 are engaged, they do not need to be arranged side by side in the left-right direction, but can be at least partially stacked in the up-down direction, so that the space occupied in the left-right direction is smaller, and there is enough space for other components to be arranged, and the arrangement of each gear can be flexibly adjusted according to the component structure of the specific vehicle, and the internal structure of the vehicle can be more optimized.

[0056] It can be understood that when the axle 100 is suitable for being connected with the front wheels 301 of the vehicle, the vehicle is a front-drive vehicle, and when the axle 100 is suitable for being connected with the rear wheels 302 of the vehicle, the vehicle is a rear-drive vehicle. Preferably, the axle body 1 is provided with two sets, and the first output shaft 31 is in driving connection with the axle shafts 12 of the two sets of axle bodies 1, so that the front and rear wheels can be driven by one driving motor 2 and one transmission 3, realizing four-wheel drive and stronger driving capability, and better ensuring the vehicle escape performance.

[0058] Preferably, the driving motor 2 of the axle 100 is located at the front side of the axle shaft 12, and the transmission 3 is arranged at the rear side of the axle shaft 12, so as to reduce the torque of the driving motor 2 and increase the product competitiveness.

[0059] Moreover, when the axle body 1 is provided with two sets, the two sets of axle bodies 1 are arranged in a spaced manner along the front-rear direction of the loader body 200, the axle shaft 12 of the axle body 1 located at the front end is connected with the two front wheels 301, the axle shaft 12 of the axle body 1 located at the rear end is connected with the two rear wheels 302, the driving motor 2 and the transmission 3 are both arranged in one set and correspondingly arranged at the axle body 1 located at the front end, and the first output shaft 31 of the transmission 3 is in driving connection with the axle shaft 12 of the two sets of axle bodies 1, so as to drive the front and rear wheels to rotate.

[0060] Specifically, two first bevel gears 35 can be arranged on the first output shaft 31, one second bevel gear 11 is arranged on the front axle shaft 12, and one second bevel gear 11 is arranged on the rear axle shaft 12, and the two first bevel gears 35 and the two second bevel gears 11 are arranged in one-to-one corresponding engagement. When the driving motor 2 drives the second output shaft 4 to rotate, the first gear 321 or the third gear 332 can be driven to rotate, thereby driving the second gear 322 or the fourth gear 333 to rotate, so that the first output gear 341 rotates together, and when the second output gear 342 rotates, the first output shaft 31 is driven to rotate, thereby the two first bevel gears 35 can rotate together, driving the two second bevel gears 11 to rotate, thereby driving the wheel set to rotate, so as to control the vehicle to travel, the driving components are less, the cost is lower, and four-wheel drive can be realized, and the vehicle has better escape performance.
