[0043] The following specific implementation is only for describing a wading road surface. The muddy road and rocky road surface are the same as those described above, and the only difference is the adjustment angle of the driving wheel flip. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0058] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0059] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0060] For example 1, please refer to Figures 1 to 12 A dual-mode single-axle interconnected active hydraulic suspension mechanism for a trailer includes a base plate 1, symmetrically arranged support arms 101 are fixed to both ends of the base plate 1, and two flip plates 3 are provided at the bottom of the base plate 1, and the two flip plates 3 are rotatably connected to the support arms 101;

[0061] Shock-absorbing components, which are arranged at both ends of the substrate 1 and connect the two flip plates 3 and both ends of the substrate 1;

[0062] An adjusting component is installed at the bottom of the base plate 1 and is connected to the two flip plates 3. The adjusting component drives the two flip plates 3 to flip relative to each other;

[0063] A mounting base 6 is fixed to the bottom of the base plate 1 , and a driving component is installed on the mounting base 6 , and the driving component is connected to the vehicle driving wheel and the adjusting component.

[0064] In the embodiment of the present invention, the shock absorbing assembly absorbs the bumps during the vehicle journey, so that the vehicle has a more comfortable driving experience;

[0065] When the adjustment assembly is working, the two flip plates 3 are driven to flip in opposite directions. When the two flip plates 3 flip, the two rear drive wheels of the vehicle are driven to flip relative to each other while adjusting the shock absorbing assembly.

[0066] When the driving component is working, the two rear drive wheels of the vehicle are driven to rotate synchronously, so that the vehicle is driven forward / backward by the rotation of the drive wheels. When the adjusting component is working, when the two rear drive wheels are driven to flip, the two rear drive wheels are driven to rotate relative to each other. By adjusting the drive to a tilted state, when the vehicle enters the water, the two relatively rotating drive wheels provide propulsion to the vehicle.

[0067] The shock absorbing assembly includes an upper swing arm 2 and a lower swing arm 201, wherein the lower swing arm 201 and the upper swing arm 2 are rotatably connected to both ends of the flip plate 3, and a disc 7 is rotatably mounted on one end of the lower swing arm 201 and the upper swing arm 2 away from the flip plate 3;

[0068] The upper swing arm 2 and the lower swing arm 201 are both provided with a through slot 202;

[0069] The shock absorber 5 is rotatably mounted on the lower swing arm 201 . The shock absorber 5 passes through the through slot 202 on the upper swing arm 2 and is rotatably connected to one end of the base plate 1 . A shock absorbing spring 501 is sleeved on the shock absorber 5 .

[0070] In the embodiment of the present invention, when the adjustment assembly is working, the flip plate 3 is driven to flip. When the flip plate 3 flips, the upper swing arm 2 is driven to move toward the disk body 7, and the lower swing arm 201 is driven to move away from the disk body 7, thereby driving the disk body 7 to flip from the upright state to the inclined state. Figure 4 and Figure 5 ;

[0071] Under normal conditions, the drive wheels are in an upright position. When the vehicle enters the water, the two drive wheels rotate to drive the vehicle forward. However, the water flow will come into contact with the bottom of the vehicle, which will significantly reduce the thrust. The two drive wheels are adjusted to an inclined position to solve the above problem.

[0072] Secondly, the method of driving the upper swing arm 2 and the lower swing arm 201 to flip the disc body 7 by the flip plate 3 is more reliable and stable than the existing electronic device method of driving the two drive wheels to flip. In addition, the angle of the disc body 7 from the starting end to the end of the stroke adjustment axis using this adjustment method is greater than 80 degrees, thereby making the drive wheel closer to the horizontal state.

[0073] The shock absorber 5 and the shock absorbing spring 501 are used to support the vehicle. Since the upper swing arm 2 and the lower swing arm 201 move synchronously, there is a linkage relationship between the two. The shock absorber 5 and the shock absorbing spring 501 are connected to the lower swing arm 201, and their shock absorbing force can act on the upper swing arm 2 at the same time.

[0074] When the driving wheel and the disc body 7 are adjusted from the upright state to the inclined state, the shock absorber 5 and the shock absorbing spring 501 will be gradually compressed.

[0075] The adjustment assembly includes two bidirectional screw rods 303 rotatably mounted on the bottom of the base plate 1. The two bidirectional screw rods 303 are connected by a first transmission chain 304. Both ends of the two bidirectional screw rods 303 are sleeved with sliders 302 threadedly engaged therewith. The two sliders 302 are slidably connected to the bottom of the base plate 1.

[0076] The bottom of the two sliders 302 are hinged with a transmission plate 301, and the ends of the two transmission plates 301 away from the sliders 302 are hinged to the flip plate 3, and the two sliders 302 are connected to the driving assembly;

[0077] One of the bidirectional screw rods 303 is connected to a driving member.

[0078] In the embodiment of the present invention, the driving member is a device that drives one of the bidirectional screw rods 303 to rotate, and the specific structure thereof is not specifically limited in the present invention;

[0079] When the driving member is working, it drives one of the two-way screw rods 303 to rotate. When one of the two-way screw rods 303 rotates, the first two-way screw rod 303 is driven to rotate through the first transmission chain 304, so as to drive the two two-way screw rods 303 to rotate synchronously.

[0080] When the two-way screw rod 303 rotates, the two sliders 302 are driven to rotate relative to each other or oppositely by cooperating with the threads of the sliders 302. When the two sliders 302 rotate relative to each other, the two flip plates 3 are pulled to rotate by the transmission plate 301, and vice versa, the two flip plates 3 are driven to reset. When the two sliders 302 move relative to each other, they also drive the driving assembly to work.

[0081] The connection position between the transmission plate 301 and the flip plate 3 is the bottom of one side of the flip plate 3 .

[0082] Embodiment 2 is distinguished from Embodiment 1 in that: the drive assembly includes a No. 1 transmission rod 4 and a No. 2 transmission rod 401 rotatably mounted on the support arm 101, a universal coupling 403 is coaxially fixed to opposite ends of the No. 2 transmission rod 401 and the No. 1 transmission rod 4, a No. 3 transmission rod 402 is coaxially fixed to one end of the universal coupling 403 away from the No. 2 transmission rod 401 and the No. 1 transmission rod 4, and the No. 3 transmission rod 402 is rotatably connected to the disk body 7;

[0083] The first transmission rod 4 and the second transmission rod 401 are connected to form a power output assembly between the first transmission rod 4 and the second transmission rod 401 .

[0084] In this embodiment of the present invention, the power of the engine is transmitted to the first transmission rod 4 and the second transmission rod 401 through the power output assembly, so that the second transmission rod 401 and the first transmission rod 4 rotate synchronously. When the second transmission rod 401 rotates, the third transmission rod 402 is driven to rotate through the universal joint 403. When the third transmission rod 402 rotates, the drive wheel is driven to rotate through another universal joint 403.

[0085] Among them, adopting this method, when the vehicle is bumpy or the driving wheel is adjusted, the power of the No. 2 transmission rod 401 and the No. 2 transmission rod 401 and the driving wheel will not be cut off. The method of transmitting the driving force to the driving wheel is a relatively mature existing technology and will not be elaborated on here.

[0086] The power output assembly includes a slide 901 fixed to the bottom of the mounting base 6, and a fifth transmission rod 9 is movably mounted in the slide 901. The fifth transmission rod 9 is connected to the first transmission rod 4 and the second transmission rod 401 through a power distribution assembly;

[0087] The fifth transmission rod 9 is connected to the slider 302 via a follower assembly;

[0088] A slide bar 903 is coaxially slidably installed on one end of the No. 5 transmission rod 9 away from the slide cylinder 901, and a plurality of transmission bars 9012 are fixed on the circumference of the slide bar 903 at equal intervals. The transmission bars 9012 slide in cooperation with the transmission grooves 9013 opened on the inner wall of the No. 5 transmission rod 9.

[0089] In the embodiment of the present invention, the slide bar 903 is connected to the power delivery end of the engine, and drives the slide bar 903 to rotate when the engine is working. When the slide bar 903 rotates, the transmission bar 9012 and the transmission slot 9013 cooperate to drive the fifth transmission rod 9 to rotate. When the fifth transmission rod 9 rotates, the power is transmitted to the first transmission rod 4 and the second transmission rod 401 through the power distribution assembly, thereby driving the first transmission rod 4 and the second transmission rod 401 to rotate;

[0090] Among them, when the two sliders 302 move relative to each other, they drive the two No. 1 transmission rods 4 to flip and drive the follower assembly to work, and the distribution mode of the power distribution assembly is switched through the follower assembly:

[0091] Distribution mode 1: when the fifth transmission rod 9 rotates, the power distribution assembly drives the first transmission rod 4 and the second transmission rod 401 to rotate in the same direction. This power distribution mode is when the driving wheel is in the state;

[0092] Distribution mode 2: When the fifth transmission rod 9 rotates, the power distribution assembly drives the first transmission rod 4 and the second transmission rod 401 to rotate relative to each other. This power distribution mode is used when the driving wheel is adjusted to a tilted state;

[0093] The movable connection between the fifth transmission rod 9 and the slide cylinder 901 means that the fifth transmission rod 9 can rotate or slide axially inside the slide cylinder 901 .

[0094] The power distribution assembly includes a second bevel gear 905 and a first bevel gear 904 coaxially fixed to the fifth transmission rod 9, and the first bevel gear 904 and the second bevel gear 905 are arranged opposite to each other;

[0095] A fifth bevel gear 908 is coaxially fixed to the opposite ends of the first transmission rod 4 and the second transmission rod 401. The two fifth bevel gears 908 cooperate with the second bevel gear 905.

[0096] A third bevel gear 906 is coaxially fixed to the first transmission rod 4, and a fourth bevel gear 907 is rotatably mounted on the second transmission rod 401. The fourth bevel gear 907 is connected to the second transmission rod 401 through a direction-adjusting member, and the first bevel gear 904 cooperates with the third bevel gear 906 and the fourth bevel gear 907.

[0097] In the embodiment of the present invention, when the fifth transmission rod 9 rotates, it drives the second bevel gear 905 and the first bevel gear 904 to rotate synchronously. When the second bevel gear 905 is engaged with the two fifth bevel gears 908, the two fifth bevel gears 908 are driven to rotate synchronously in the same direction. The corresponding first transmission rod 4 and the second transmission rod 401 and the two power wheels rotate synchronously in the same direction. When the first bevel gear 904 is engaged with the third bevel gear 906 and the fourth bevel gear 907, the second bevel gear 905 is disengaged from the fifth bevel gear 908 to rotate synchronously through the first bevel gear 90 The meshing of the bevel gear 4 with the fourth bevel gear 907 and the third bevel gear 906 drives the two to rotate synchronously in the same direction. When the third bevel gear 906 rotates, the first transmission rod 4 is driven to rotate accordingly. When the fourth bevel gear 907 rotates, since the fourth bevel gear 907 is installed on the second transmission rod 401 for rotation, it does not directly drive the second transmission rod 401 to rotate. When the fourth bevel gear 907 rotates, the second transmission rod 401 is driven to rotate in the opposite direction through the direction adjustment component, thereby realizing that the first transmission rod 4 and the second transmission rod 401 rotate in opposite directions and the corresponding power wheels rotate in opposite directions.

[0098] The steering member includes an annular groove formed on the back of the fourth bevel gear 907, in which a third gear 909 is rotatably mounted. The third gear 909 meshes with a second gear ring 9011 disposed in the annular groove. A first gear ring 9010 is coaxially fixed to the second transmission rod 401, and the first gear ring 9010 meshes with the third gear 909.

[0099] The third gear 909 is rotatably connected to the mounting base 6 ; a pull arm for supporting the second transmission rod 401 is integrated on the mounting base 6 , and the third gear 909 is rotatably mounted on the pull arm.

[0100] In the embodiment of the present invention, when the fifth transmission rod 9 rotates, the third bevel gear 906 and the fourth bevel gear 907 are synchronously driven to rotate in the same direction through the first bevel gear 904. When the third bevel gear 906 rotates, the first transmission rod 4 is driven to rotate accordingly. When the fourth bevel gear 907 rotates, since the fourth bevel gear 907 is rotationally connected to the second transmission rod 401, the second transmission rod 401 is not directly driven to rotate. When the fourth bevel gear 907 rotates, the third gear 909 is driven to rotate through the second gear ring 9011. When the third gear 909 rotates, the first gear ring 9010 is driven to rotate in the opposite direction through engagement with the first gear ring 9010, so that the first transmission rod 4 and the second transmission rod 401 rotate in opposite directions, and the corresponding two driving wheels rotate in opposite directions.

[0101] Among them, the transmission ratios between the No. 1 bevel gear 904 and the No. 3 bevel gear 906 and between the No. 3 bevel gear 906 and the No. 4 bevel gear 907 are adjusted according to actual production so that the No. 1 bevel gear 904 drives the No. 1 transmission rod 4 and the No. 2 transmission rod 401 to have the same rotation speed when rotating. Therefore, the present invention does not specifically limit the transmission ratios between the No. 4 bevel gear 907 and the No. 3 bevel gear 906 and the No. 1 bevel gear 904. The transmission ratio between the No. 2 bevel gear 905 and the two No. 5 bevel gears 908 is one to one.
