[0043] In the description of this utility model, "first feature" and "second feature" may include one or more of the features.
[0044] In the description of this utility model, "multiple" means two or more, and "several" means one or more.
[0045] The axle assembly 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.
[0046] like Figures 1-5 As shown in the attached diagram, the left and right directions are the same as the left and right directions of the axle assembly 1.
[0047] like Figure 5 As shown, the axle assembly 1 includes an axle housing 100, an input shaft 110, an output shaft 120, and a reversing mechanism 130. The axle housing 100 provides mounting positions for the components of the axle assembly 1, protecting them from impurities and dust falling into the axle housing 100, thereby enabling the axle assembly 1 to operate stably.
[0048] The input shaft 110 is rotatably fixed inside the bridge housing 100, the output shaft 120 is rotatably fixed to the bridge housing 100 and is selectively connected to the input shaft 110 in a transmission manner, and the reversing mechanism 130 is connected to the input shaft 110 and the output shaft 120 in a transmission manner respectively.
[0049] When the input shaft 110 and the output shaft 120 are connected by a transmission, the input shaft 110 drives the output shaft 120 to rotate in the forward direction; when the input shaft 110 and the output shaft 120 are disconnected from the transmission, the input shaft 110 drives the output shaft 120 to rotate in the reverse direction through the reversing mechanism 130.
[0050] The input shaft 110 can be multiple and arranged on both sides of the axle assembly 1 in the left-right direction, and the output shaft 120 can be multiple and arranged on both sides of the axle assembly 1 in the left-right direction. For example, one input shaft 110 and one output shaft 120 can be arranged on the left side, and the power assembly can output power to the wheels on the left side through the one input shaft 110 and the one output shaft 120, and another input shaft 110 and another output shaft 120 can be arranged on the right side, and the power assembly can output power to the wheels on the right side through the another input shaft 110 and the another output shaft 120.
[0051] In addition, the output shaft 120 is selectively drivingly connected with the input shaft 110, which means that the output shaft 120 can be drivingly connected with the input shaft 110, at this time the input shaft 110 can directly transmit power to the output shaft 120, or the input shaft 110 can be disconnected from the output shaft 120, at this time the input shaft 110 cannot directly output power to the output shaft 120.
[0052] In addition, the output shaft 120 rotates in the forward direction and the reverse direction, which means that the output shaft 120 can rotate in two opposite directions. For example, when the output shaft 120 rotates in the forward direction, the wheels can rotate forward, and when the output shaft 120 rotates in the reverse direction, the wheels can rotate backward.
[0053] According to the axle assembly 1 of the embodiment of the utility model, by setting the reversing mechanism 130, when the input shaft 110 and the output shaft 120 are drivingly connected, the input shaft 110 can directly drive the output shaft 120 to rotate in the forward direction, and when the input shaft 110 and the output shaft 120 are disconnected, the input shaft 110 drives the output shaft 120 to rotate in the reverse direction through the reversing mechanism 130. In this way, when the vehicle travels forward, the input shaft 110 and the output shaft 120 on the left and right sides can be drivingly connected, at this time the output shaft 120 on the left and right sides can rotate in the forward direction, and the drive wheels on the left and right sides can be driven to rotate in the same direction, so that the vehicle travels forward.
[0054] When the vehicle needs to turn or U-turn on a narrow road section, for example, when the vehicle needs to turn left or U-turn, the input shaft 110 and the output shaft 120 on the left side can be disconnected, and the input shaft 110 and the output shaft 120 on the right side can be drivingly connected. At this time, the input shaft 110 on the left side can drive the output shaft 120 on the left side to rotate in the reverse direction through a reversing mechanism 130, and the input shaft 110 on the right side can directly drive the output shaft 120 to rotate in the forward direction, that is, the output shaft 120 on the left side and the output shaft 120 on the right side can rotate in opposite directions. In this way, the output shaft 120 on the left side can drive the drive wheels on the left side to rotate backward, and the output shaft 120 on the right side can drive the drive wheels on the right side to rotate forward, so that the vehicle can be driven to turn left or U-turn, and the turning radius of the vehicle can be greatly reduced to facilitate the vehicle to turn or U-turn on a narrow road section.
[0055] Similarly, when the vehicle needs to turn right or make a U-turn on a narrow road section, the right input shaft 110 can be disconnected from the output shaft 120, and the left input shaft 110 can be connected to the output shaft 120. At this time, the right input shaft 110 can drive the right output shaft 120 to rotate in the opposite direction through a reversing mechanism 130, and the left input shaft 110 can directly drive the output shaft 120 to rotate in the positive direction, that is, the right output shaft 120 and the left output shaft 120 can rotate in opposite directions. In this way, the right output shaft 120 can drive the right drive wheel to rotate backward, and the left output shaft 120 can drive the left drive wheel to rotate forward, thereby driving the vehicle to turn right or make a U-turn, and greatly reducing the turning radius of the vehicle to facilitate the vehicle to turn or make a U-turn on a narrow road section.
[0056] Furthermore, the input shaft 110 can drive the output shaft 120 to rotate in the positive direction and the opposite direction through two paths, respectively, that is, the input shaft 110 can directly drive the output shaft 120 to rotate in the positive direction, or the input shaft 110 can drive the output shaft 120 to rotate in the opposite direction through the reversing mechanism 130, and the two paths are not easy to interfere with each other, and the structure is more reasonable. And the reverse rotation of the wheels on both sides can be controlled separately through multiple reversing mechanisms 130, which is convenient to adjust.
[0057] In this way, the axle assembly 1 according to the embodiments of the present application can realize the same direction or opposite direction rotation of the drive wheels on both sides, thereby reducing the turning radius of the vehicle to facilitate the vehicle to turn on a narrow road section or even make a U-turn in place, and the axle assembly 1 can transmit power through different paths, and the adjusting structure is simple and convenient to realize.
[0058] In some specific embodiments of the present application, as shown in Figure 2 The axle assembly 1 further comprises an inter-shaft clutch 600. The inter-shaft clutch 600 can be a hydraulic clutch.
[0059] The inter-shaft clutch 600 is arranged between the input shaft 110 and the output shaft 120, and the inter-shaft clutch 600 is used to connect or disconnect the power transmission between the input shaft 110 and the output shaft 120. In this way, the transmission connection or disconnection between the input shaft 110 and the output shaft 120 can be controlled through the inter-shaft clutch 600, and the structure is simple and convenient to realize.
[0060] In some specific embodiments of the present application, as shown in Figure 2 The input shaft 110 comprises a first input shaft 210 and a second input shaft 310, and the output shaft 120 comprises a first output shaft 220 and a second output shaft 320. In addition, the reversing mechanism 130 comprises a first reversing mechanism 510 and a second reversing mechanism 520.
[0061] The first input shaft 210 and the first output shaft 220 are rotatably fixed in the axle housing 100, the first input shaft 210 and the first output shaft 220 are coaxially arranged and selectively drivingly connected, the second input shaft 310 and the second output shaft 320 are rotatably fixed in the axle housing 100, the second input shaft 310 and the second output shaft 320 are coaxially arranged and selectively drivingly connected, the differential 400 is adapted to be drivingly connected with the power assembly, and the differential 400 is connected with one end of the first input shaft 210 and one end of the second input shaft 310 respectively, the first reversing mechanism 510 is drivingly connected with the first input shaft 210 and the first output shaft 220 respectively, and the second reversing mechanism 520 is drivingly connected with the second input shaft 310 and the second output shaft 320 respectively.
[0062] When the first input shaft 210 and the first output shaft 220 are drivingly connected, the first input shaft 210 drives the first output shaft 220 to rotate in the same direction, and when the first input shaft 210 and the first output shaft 220 are disconnected, the first input shaft 210 drives the first output shaft 220 to rotate in the opposite direction through the first reversing mechanism 510.
[0063] In addition, when the second input shaft 310 and the second output shaft 320 are drivingly connected, the second input shaft 310 drives the second output shaft 320 to rotate in the same direction, and when the second input shaft 310 and the second output shaft 320 are disconnected, the second input shaft 310 drives the second output shaft 320 to rotate in the opposite direction through the second reversing mechanism 520.
[0064] The first input shaft 210 and the first output shaft 220 can extend in the left-right direction, the second input shaft 310 and the second output shaft 320 can extend in the left-right direction, and the first input shaft 210 and the first output shaft 220 can be arranged on one side of the axle assembly 1 in the left-right direction, and the second input shaft 310 and the second output shaft 320 can be arranged on the other side of the axle assembly 1 in the left-right direction. For example, the first input shaft 210 and the first output shaft 220 can be arranged on the left side, the power assembly can output power to the left wheels through the first output shaft 220, and the second input shaft 310 and the second output shaft 320 can be arranged on the right side, and the power assembly can output power to the right wheels through the second output shaft 320.
[0065] In addition, the first input shaft 210 and the first output shaft 220 are coaxially arranged and selectively drivingly connected, which means that the first input shaft 210 can be drivingly connected with the first output shaft 220, at this time the first input shaft 210 can directly transmit power to the first output shaft 220, or the first input shaft 210 can be disconnected from the first output shaft 220, at this time the first input shaft 210 cannot directly output power to the first output shaft 220.
[0066] And, the second input shaft 310 and the second output shaft 320 are coaxially arranged and selectively drivingly connected, that is, the second input shaft 310 can be drivingly connected with the second output shaft 320, at this time, the second input shaft 310 can directly transmit power to the second output shaft 320, or the second input shaft 310 can be disconnected from the second output shaft 320, at this time, the second input shaft 310 cannot directly output power to the second output shaft 320.
[0067] Wherein, the differential mechanism 400 is adapted to be drivingly connected with a power assembly, which can be an electric motor and / or an engine. The differential mechanism 400 can realize differential rotation of the first input shaft 210 and the second input shaft 310, and then can realize that the output shafts on both sides output power to the wheels on both sides at different speeds through the differential mechanism 400, so as to realize the turning of the vehicle and facilitate the forward driving of the vehicle on uneven road surface.
[0068] According to the axle assembly 1 of the embodiment of the utility model, when the first input shaft 210 and the first output shaft 220 are drivingly connected, the first input shaft 210 directly drives the first output shaft 220 to rotate in the same direction, and when the first input shaft 210 and the first output shaft 220 are disconnected, the first input shaft 210 drives the first output shaft 220 to rotate in the opposite direction through the first reversing mechanism 510. And, when the second input shaft 310 and the second output shaft 320 are drivingly connected, the second input shaft 310 drives the second output shaft 320 to rotate in the same direction, and when the second input shaft 310 and the second output shaft 320 are disconnected, the second input shaft 310 drives the second output shaft 320 to rotate in the opposite direction through the second reversing mechanism 520.
[0069] In this way, when the vehicle drives forward, the first input shaft 210 and the first output shaft 220 are drivingly connected, and the second input shaft 310 and the second output shaft 320 are drivingly connected. At this time, the first output shaft 220 and the first input shaft 210 rotate in the same direction, and the second output shaft 320 and the second input shaft 310 rotate in the same direction, that is, the first output shaft 220 and the second output shaft 320 can rotate in the same direction, and then can drive the driving wheels on both sides to rotate in the same direction to drive the vehicle to drive forward.
[0070] When the vehicle needs to turn or reverse in a narrow road section, for example, the vehicle needs to turn or reverse to the left, the first input shaft 210 can be disconnected from the first output shaft 220, and the second input shaft 310 and the second output shaft 320 are drivingly connected. At this time, the first input shaft 210 can drive the first output shaft 220 to rotate in the opposite direction through the first reversing mechanism 510, and the second input shaft 310 directly drives the second output shaft 320 to rotate in the same direction, that is, the first output shaft 220 and the second output shaft 320 can rotate in opposite directions, for example, the first output shaft 220 can drive the left drive wheel to rotate backward, and the second output shaft 320 can drive the right drive wheel to rotate forward, thereby driving the vehicle to turn or reverse to the left, and the turning radius of the vehicle can be greatly reduced to facilitate the vehicle to turn or reverse in a narrow road section.
[0071] Similarly, when the vehicle needs to turn or reverse to the right in a narrow road section, the first input shaft 210 can be drivingly connected to the first output shaft 220, and the second input shaft 310 and the second output shaft 320 are disconnected. At this time, the first input shaft 210 can directly drive the first output shaft 220 to rotate in the same direction, and the second input shaft 310 drives the second output shaft 320 to rotate in the opposite direction through the second reversing mechanism 520, that is, the first output shaft 220 and the second output shaft 320 can rotate in opposite directions, for example, the first output shaft 220 can drive the left drive wheel to rotate forward, and the second output shaft 320 can drive the right drive wheel to rotate backward, thereby driving the vehicle to turn or reverse to the right, and the turning radius of the vehicle can be greatly reduced to facilitate the vehicle to turn or reverse in a narrow road section.
[0072] Moreover, the first input shaft 210 drives the first output shaft 220 to rotate in the same direction and in the opposite direction through two paths respectively, that is, the first input shaft 210 can directly drive the first output shaft 220 to rotate in the same direction, or the first input shaft 210 can drive the first output shaft 220 to rotate in the opposite direction through the first reversing mechanism 510, the two paths are not easy to interfere, and the switching and adjustment are convenient, and the structure is more reasonable. And the second input shaft 310 drives the second output shaft 320 to rotate in the same direction and in the opposite direction through two paths respectively, that is, the second input shaft 310 can directly drive the second output shaft 320 to rotate in the same direction, or the second input shaft 310 can drive the second output shaft 320 to rotate in the opposite direction through the second reversing mechanism 520, the two paths are not easy to interfere, and the switching and adjustment are convenient, and the structure is more reasonable. Moreover, the reverse rotation of the wheels on both sides can be controlled separately through the first reversing mechanism 510 and the second reversing mechanism 520, which is convenient for adjustment.
[0073] Thus, the axle assembly 1 can drive the left and right drive wheels to rotate in the same direction or in the opposite direction, so that the turning radius of the vehicle can be reduced, and the vehicle can turn or even U-turn in a narrow road.
[0074] In some embodiments of the present application, as shown in Figure 4 The axle assembly 1 further comprises a first interaxle clutch 610 and a second interaxle clutch 620. The first interaxle clutch 610 and the second interaxle clutch 620 can be hydraulic clutches.
[0075] The first interaxle clutch 610 is arranged between the first input shaft 210 and the first output shaft 220, and is used to connect or disconnect the power transmission between the first input shaft 210 and the first output shaft 220. The second interaxle clutch 620 is arranged between the second input shaft 310 and the second output shaft 320, and is used to connect or disconnect the power transmission between the second input shaft 310 and the second output shaft 320.
[0076] Therefore, when the first interaxle clutch 610 connects the first input shaft 210 and the first output shaft 220, and the second interaxle clutch 620 connects the second input shaft 310 and the second output shaft 320, the differential 400 can directly transmit the power of the power assembly to the first output shaft 220 through the first input shaft 210 and the first interaxle clutch 610, thereby driving the left drive wheel to rotate in the same direction. In addition, the differential 400 can directly transmit the power of the power assembly to the second output shaft 320 through the second input shaft 310 and the second interaxle clutch 620, thereby driving the right drive wheel to rotate in the same direction, so that the left and right drive wheels can rotate in the same direction, and the vehicle can travel stably forward.
[0077] In addition, when the first interaxle clutch 610 disconnects the transmission connection between the first input shaft 210 and the first output shaft 220, and the second interaxle clutch 620 connects the second input shaft 310 and the second output shaft 320, the differential 400 can transmit the power of the power assembly to the first output shaft 220 through the first input shaft 210 and the first reversing mechanism 510 in sequence, thereby driving the left drive wheel to rotate in the opposite direction. At the same time, the differential 400 can directly transmit the power of the power assembly to the second output shaft 320 through the second input shaft 310 and the second interaxle clutch 620, thereby driving the right drive wheel to rotate in the same direction, so that the vehicle can turn left or U-turn, and the turning radius of the vehicle can be greatly reduced, so that the vehicle can turn left or U-turn in a narrow road.
[0078] In addition, when the first inter-axle clutch 610 connects the first input shaft 210 and the first output shaft 220, and the second inter-axle clutch 620 disconnects the transmission connection between the second input shaft 310 and the second output shaft 320, the differential 400 can directly transmit the power of the power assembly to the first output shaft 220 through the first input shaft 210 and the first inter-axle clutch 610, and then can drive the left drive wheel to rotate in the same direction, at the same time, the differential 400 can transmit the power of the power assembly to the second output shaft 320 through the second input shaft 310 and the second reversing mechanism 520 in turn, to drive the right drive wheel to rotate in the opposite direction, thereby driving the vehicle to turn right or U-turn, and the turning radius of the vehicle can be greatly reduced, so as to facilitate the vehicle to turn right or U-turn in a narrow road section.
[0079] In some embodiments of the present application, as shown in Figure 2 and Figure 3 The axle assembly 1 further comprises a first output gear 710 and a first drive gear 720, and a second output gear 730 and a second drive gear 740.
[0080] The first output gear 710 is connected to the other end of the first input shaft 210, and the first drive gear 720 is connected to the first output shaft 220, and the first reversing mechanism 510 is drivingly connected with the first output gear 710 and the first drive gear 720 respectively.
[0081] In addition, the second output gear 730 is connected to the other end of the second input shaft 310, and the second drive gear 740 is connected to the second output shaft 320, and the second reversing mechanism 520 is drivingly connected with the second output gear 730 and the second drive gear 740 respectively.
[0082] Specifically, the first output gear 710 is drivingly connected with the first input shaft 210, that is, the first output gear 710 can rotate synchronously with the first input shaft 210, and the first drive gear 720 is drivingly connected with the first output shaft 220, that is, the first drive gear 720 can rotate synchronously with the first output shaft 220. In this way, the differential 400 can transmit the power of the power assembly to the first output shaft 220 through the first input shaft 210, the first output gear 710, the first reversing mechanism 510 and the first drive gear 720 in turn, to drive the left drive wheel to rotate through the first output shaft 220.
[0083] In addition, the second output gear 730 is in driving connection with the second input shaft 310, that is, the second output gear 730 can rotate synchronously with the second input shaft 310, and the second driving gear 740 is in driving connection with the second output shaft 320, that is, the second driving gear 740 can be in driving connection with the second output shaft 320. In this way, the differential 400 can transmit the power of the power assembly to the second output shaft 320 through the second input shaft 310, the second output gear 730, the second reversing mechanism 520 and the second driving gear 740 in sequence, so as to drive the right driving wheel to rotate through the second output shaft 320.
[0084] In some specific embodiments of the utility model, as shown in Figures 2-4 The first reversing mechanism 510 and the second reversing mechanism 520 both include a driven shaft 531, a first driven gear 532, a second driven gear 533, a reversing gear 535 and a shift lever assembly 536.
[0085] The driven shaft 531 is rotatably connected in the axle housing 100, the first driven gear 532 is connected to the driven shaft 531, and the first driven gear 532 is in mesh with the first output gear 710 or the second output gear 730, the second driven gear 533 is movably connected to the driven shaft 531 and is arranged in a spaced manner with the first driven gear 532, the reversing gear 535 is rotatably connected to the axle housing 100, and one side of the reversing gear 535 is in mesh with the first driving gear 720 or the second driving gear 740, the shift lever assembly 536 is arranged in the axle housing 100, and the shift lever assembly 536 is used to drive the second driven gear 533 to move along the axial direction of the driven shaft 531, so as to drive the second driven gear 533 to mesh with or separate from the other side of the reversing gear 535.
[0086] Wherein, the first driven gear 532 is in mesh with the first output gear 710 or the second output gear 730, that is, the first driven gear 532 in the first reversing mechanism 510 is in mesh with the first output gear 710, and the first driven gear 532 in the second reversing mechanism 520 is in mesh with the second output gear 730.
[0087] In addition, one side of the reversing gear 535 is in mesh with the first driving gear 720 or the second driving gear 740, that is, one side of the reversing gear 535 in the first reversing mechanism 510 is in mesh with the first driving gear 720, and the other side of the reversing gear 535 can be selectively meshed with the second driven gear 533. In this way, the reversing gear 535 can be arranged between the second driven gear 533 and the first driving gear 720, the reversing gear 535 can make the first driving gear 720 and the second driven gear 533 rotate in the same direction, so that the first driving gear 720 can rotate in the opposite direction with the first output gear 710.
[0088] And, one side of the reversing gear 535 in the second reversing mechanism 520 is engaged with the second driving gear 740, and the other side of the reversing gear 535 is selectively engaged with the second driven gear 533. In this way, the reversing gear 535 can be arranged between the second driven gear 533 and the second driving gear 740, and the reversing gear 535 can make the second driving gear 740 rotate in the same direction as the second driven gear 533, so that the second driving gear 740 can rotate in the opposite direction of the second output gear 730.
[0089] In addition, by arranging the fork assembly 536, the fork assembly 536 can drive the second driven gear 533 to engage or disengage with the reversing gear 535. Specifically, when the first input shaft 210 and the first output shaft 220 are disconnected, the first reversing mechanism 510 can drive the second driven gear 533 to engage with the reversing gear 535 through the fork assembly 536, and the second driven gear 533 can transmit power to the first driving gear 720 through the reversing gear 535, so that the first output gear 710 can transmit power to the first driving gear 720 through the first reversing mechanism 510, thereby driving the first output shaft 220 to rotate in the opposite direction; and when the first input shaft 210 and the first output shaft 220 are in driving connection, the first reversing mechanism 510 can drive the second driven gear 533 to disengage with the reversing gear 535 through the fork assembly 536, and at this time the first input shaft 210 can directly transmit power to the first output shaft 220, thereby driving the first output shaft 220 to rotate in the same direction.
[0090] Similarly, when the second input shaft 310 and the second output shaft 320 are disconnected, the second reversing mechanism 520 can drive the second driven gear 533 to engage with the reversing gear 535 through the fork assembly 536, and the second driven gear 533 can transmit power to the second driving gear 740 through the reversing gear 535, so that the second output gear 730 can transmit power to the second driving gear 740 through the second reversing mechanism 520, thereby driving the second output shaft 320 to rotate in the opposite direction; and when the second input shaft 310 and the second output shaft 320 are in driving connection, the second reversing mechanism 520 can drive the second driven gear 533 to disengage with the reversing gear 535 through the fork assembly 536, and at this time the second input shaft 310 can directly transmit power to the second output shaft 320, thereby driving the second output shaft 320 to rotate in the same direction.
[0091] In some embodiments of the present application, as shown in Figures 2-4 The fork assembly 536 includes a driving motor 537 and a fork 538.
[0092] The driving motor 537 is fixed in the axle housing 100, the shift fork 538 is connected to the motor shaft of the driving motor 537, and the driving motor 537 is used to drive the shift fork 538 to move along the axial direction of the motor shaft, so as to drive the second driven gear 533 to move along the axial direction of the driven shaft 531 by the shift fork 538. Wherein, the axial position of the reversing gear 535 can be fixed.
[0093] In this way, by driving the shift fork 538 to move along the axial direction of the motor shaft by the driving motor 537, the second driven gear 533 can be driven to coincide with the reversing gear 535 in the axial direction of the driven shaft 531, at this time, the second driven gear 533 can be engaged with the reversing gear 535, and the second driven gear 533 can transmit power to the first driving gear 720 or the second driving gear 740 through the reversing gear 535; or, the driving motor 537 can drive the shift fork 538 to drive the second driven gear 533 to stagger with the reversing gear 535 in the axial direction of the driven shaft 531, that is, the second driven gear 533 can be arranged in a staggered manner with the reversing gear 535, so that the second driven gear 533 can be separated from the reversing gear 535, and the power transmission between the second driven gear 533 and the reversing gear 535 can be disconnected.
[0094] Specifically, when the first input shaft 210 and the first output shaft 220 are in driving connection, the driving motor 537 of the first reversing mechanism 510 can drive the second driven gear 533 to stagger with the reversing gear 535 in the axial direction of the driven shaft 531 through the shift fork 538, and when the first input shaft 210 and the first output shaft 220 are disconnected, the driving motor 537 of the first reversing mechanism 510 can drive the second driven gear 533 to engage with the reversing gear 535 through the shift fork 538.
[0095] Similarly, when the second input shaft 310 and the second output shaft 320 are in driving connection, the driving motor 537 of the second reversing mechanism 520 can drive the second driven gear 533 to stagger with the reversing gear 535 in the axial direction of the driven shaft 531 through the shift fork 538, and when the second input shaft 310 and the second output shaft 320 are disconnected, the driving motor 537 of the second reversing mechanism 520 can drive the second driven gear 533 to engage with the reversing gear 535 through the shift fork 538.
[0096] In some specific embodiments of the present application, as shown in Figures 2-4 One end of the shift fork 538 is threadedly connected to the motor shaft, and the other end of the shift fork 538 is connected to the second driven gear 533, and the second driven gear 533 is rotatable relative to the shift fork 538.
[0097] When the driving motor 537 rotates forward, the yoke 538 moves along the axial direction of the motor shaft towards the direction of the reversing gear 535, so as to push the second driven gear 533 to engage with the reversing gear 535; when the driving motor 537 rotates reversely, the yoke 538 moves along the axial direction of the motor shaft away from the reversing gear 535, so as to push the second driven gear 533 to disengage with the reversing gear 535 in the axial direction of the driven shaft 531.
[0098] Therefore, by controlling the rotating direction of the driving motor 537, the moving direction of the yoke 538 along the axial direction of the motor shaft can be changed, and then the second driven gear 533 can be driven by the yoke 538 to move back and forth along the axial direction of the driven shaft 531, so that the second driven gear 533 can be switched between the engaged state and the disengaged state with the reversing gear 535.
[0099] Specifically, taking the first reversing mechanism 510 as an example, when the driving motor 537 rotates forward, the yoke 538 moves along the axial direction of the motor shaft towards the direction of the reversing gear 535, and the second driven gear 533 is pushed by the yoke 538 to engage with the reversing gear 535, so that the differential mechanism 400 can transmit power to the first output shaft 220 through the first input shaft 210, the first output gear 710, the first driven gear 532, the driven shaft 531, the second driven gear 533, the reversing gear 535 and the first driving gear 720 in sequence, so as to drive the first output shaft 220 to rotate reversely; when the driving motor rotates reversely, the yoke 538 moves along the axial direction of the motor shaft away from the reversing gear 535, and the second driven gear 533 is pushed by the yoke 538 to disengage with the reversing gear 535, so that the differential mechanism 400 can transmit power to the first output shaft 220 through the first input shaft 210 and the first inter-shaft clutch 610, so as to drive the first output shaft 220 to rotate in the same direction.
[0100] Similarly, for the second reversing mechanism 520, when the driving motor 537 rotates forward, the yoke 538 moves along the axial direction of the motor shaft towards the direction of the reversing gear 535, and the second driven gear 533 is pushed by the yoke 538 to engage with the reversing gear 535, so that the differential mechanism 400 can transmit power to the second output shaft 320 through the second input shaft 310, the second output gear 730, the first driven gear 532, the driven shaft 531, the second driven gear 533, the reversing gear 535 and the second driving gear 740, so as to drive the second output shaft 320 to rotate reversely; when the driving motor rotates reversely, the yoke 538 moves along the axial direction of the motor shaft away from the reversing gear 535, and the second driven gear 533 is pushed by the yoke 538 to disengage with the reversing gear 535, so that the differential mechanism 400 can transmit power to the second output shaft 320 through the second input shaft 310 and the second inter-shaft clutch 620, so as to drive the second output shaft 320 to rotate in the same direction.
[0101] In some embodiments of the utility model, as shown in Figure 4 The middle part of the second driven gear 533 is provided with an annular groove 534, the annular groove 534 extends along the circumference of the second driven gear 533, and the other end of the fork 538 is arranged in the annular groove 534.
[0102] One end of the fork 538 can be threadedly connected with the motor shaft, and the other end of the fork 538 is arranged in the annular groove 534, and the mutual abutment between the other end of the fork 538 and the inner wall of the annular groove 534 can realize the fork 538 pushing the second driven gear 533 to move along the axial direction of the driven shaft 531, and then the connection state of the second driven gear 533 and the reversing gear 535 can be changed.
[0103] Moreover, by arranging the annular groove 534 and the fork 538, when the second driven gear 533 rotates, the fork 538 can slide in the annular groove 534, that is, the fork 538 does not affect the rotation of the second driven gear 533, and the structure is more reasonable.
[0104] In some embodiments of the utility model, as shown in Figure 2 And Figure 3 The differential mechanism 400 includes a first sun gear 410, a second sun gear 420, an input gear 440 and a plurality of planetary gears 430.
[0105] The first sun gear 410 is fixedly connected to the end of the first input shaft 210, the second sun gear 420 is fixedly connected to the end of the second input shaft 310, the input gear 440 is sleeved on the first input shaft 210 or the second input shaft 310, and the input gear 440 is provided with a connecting frame 441, the input gear 440 is adapted to be connected with the power assembly in transmission, the plurality of planetary gears 430 are connected to the connecting frame 441, and the plurality of planetary gears 430 are respectively engaged with the first sun gear 410 and the second sun gear 420.
[0106] Specifically, the first sun gear 410 is fixedly connected with the first input shaft 210, that is, the first sun gear 410 can rotate synchronously with the first input shaft 210 around the axial direction of the first input shaft 210, and the second sun gear 420 is fixedly connected with the second input shaft 310, that is, the second sun gear 420 can rotate synchronously with the second input shaft 310 around the axial direction of the second input shaft 310.
[0107] And the input gear 440 is sleeved on the first input shaft 210 or the second input shaft 310, and the plurality of planetary gears 430 are connected to the connecting frame 441 of the input gear 440, so that the plurality of planetary gears 430 can revolve around the central axis of the first input shaft 210 or the second input shaft 310 with the input gear 440, and the planetary gears 430 can also rotate around the axis of the planetary gears 430.
[0108] Therefore, when the vehicle is running normally, the power of the power assembly is transmitted to the input gear 440, the input gear 440 can drive the plurality of planetary gears 430 to revolve around the axis of the first input shaft 210, so that the plurality of planetary gears 430 can drive the first sun gear 410 and the second sun gear 420 to rotate to transmit power to the first input shaft 210 and the second input shaft 310, and then drive the vehicle to move forward.
[0109] When the vehicle needs to turn or the vehicle runs on uneven road, that is, the wheels on both sides of the vehicle rotate at different speeds, the differential power transmission of the two sun gears can be realized through the rotation of the planetary gears 430, so that the first input shaft 210 and the second input shaft 310 can rotate at different speeds, so that the driving wheels on both sides can rotate at different speeds, and then the vehicle can turn or move forward on uneven road.
[0110] In some specific embodiments of the present application, as shown in Figure 2 and Figure 3 The axle assembly 1 further comprises a transmission shaft 900.
[0111] One end of the transmission shaft 900 is adapted to be connected with the power assembly, and the other end of the transmission shaft 900 is provided with a bevel gear 910, which is engaged with the input gear 440. In this way, the power transmission direction of the transmission shaft 900 can be changed through the engagement transmission of the bevel gear 910 and the input gear 440, so as to facilitate the layout of the transmission shaft 900 and the axle assembly 1, and the structure is more reasonable.
