Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a dual-motor self-adaptive terrain remote-controlled four-wheel drive vehicle. Background Art

[0002] A four-wheel drive vehicle is a vehicle with front and rear differential linkage four-wheel drive. Its characteristic is that the four wheels can rotate independently, which can achieve better movement effect under complex terrain conditions. Existing four-wheel drive vehicles are mostly driven by four motors, which have the problems of high cost and complex control. Therefore, a low-cost four-wheel drive solution is needed.

[0003] The vehicle suspension system is a general term for all the force-transmitting connection devices between the vehicle frame and the axle or wheel. It can reduce vibration, protect components, and improve the ground adhesion of the wheels. Common suspension systems are divided into independent suspension and non-independent suspension. Existing four-wheel drive vehicles usually use independent suspension. Although the shock absorption effect is better, the structure is complex and the cost is high. Moreover, in the independent driving mode of the left and right motors, when the motor drives the front and rear wheels to rotate at the same time, the wheelbase on the single-side wheel frame must be kept fixed, which makes it difficult to use an independent suspension structure. Therefore, a non-independent suspension solution for dual-motor locomotives with simple structure and high strength is needed. Summary of the invention

[0039] The support portion 11 is located between the front panel 12 and the rear panel 13 , and the support portion 11 is detachably connected to the front panel 12 and the rear panel 13 .

[0040] The movable shaft 14 and the limiting plate 15 are transversely fixed to the bottom of the supporting part 11 , and the movable shaft 14 and the limiting plate 15 are respectively perpendicular to the supporting part 11 . The movable shaft 14 is located behind the limiting plate 15 .

[0041] like Figure 4 and Figure 5 As shown, a group of movable wheel suspensions 2 are respectively provided on the left and right sides of the dual-motor adaptive terrain remote-controlled four-wheel drive vehicle, and each group of movable wheel suspensions 2 includes a connecting rod 21, a motor fixing plate 22, a reduction motor 23, a spline sleeve 24, a front tooth package 251, a rear tooth package 252, a front tooth package fixing plate 26 and a rear tooth package fixing plate 27.

[0042] The connecting rod 21 is fixedly connected between the front tooth package fixing plate 26 and the back tooth package fixing plate 27.

[0043] The front tooth package 251 is located outside the front tooth package fixing plate 26 and is detachably connected to the front tooth package fixing plate 26 ; the back tooth package 252 is located outside the back tooth package fixing plate 27 and is detachably connected to the back tooth package fixing plate 27 .

[0044] The connecting rod 21 is detachably connected to the motor fixing plate 22. The reduction motor 23 is located above the motor fixing plate 22 and is detachably connected to the motor fixing plate 22. The installation position of the reduction motor 23 can be adjusted to ensure that the motor shaft and the tooth package axis are coaxial. The reduction motor 23 is connected to the front tooth package 251 and the rear tooth package 252 through a spline sleeve 24 to transmit power.

[0045] The front wheel 31 is connected to the movable wheel suspension 2 via a front toothed package 251. The rear wheel 32 is connected to the movable wheel suspension 2 via a rear toothed package 252. There are two front wheels 31 and two rear wheels 32, respectively. The two front wheels 31 are symmetrically arranged, and the two rear wheels 32 are symmetrically arranged.

[0046] The movable wheel suspension 2 is connected to the vehicle body frame 1 through a movable shaft 14 and a limit plate 15. The movable shaft 14 passes through the rear tooth package fixing plate 27 on the wheel suspension 2, which is a rotatable shaft sleeve connection. The limit plate 15 clamps the front tooth package fixing plate 26 on the wheel suspension 2, which is a movable contact connection.

[0047] The shelf 4 is located above the vehicle body frame 1 and is detachably connected to the vehicle body frame 1 .

[0048] The working process of the utility model is:

[0049] In the powered working state, the reduction motor 23 transmits power to the front tooth package 251 and the rear tooth package 252 through the spline sleeve 24, and the front tooth package 251 and the rear tooth package 252 respectively drive the front wheel 31 and the rear wheel 32 on one side to rotate, so as to realize the movement of the vehicle. When the speeds of the reduction motors 23 on the left and right sides are the same and in the same direction, the vehicle moves in a straight line; when the speeds of the reduction motors 23 on the left and right sides are inconsistent, the vehicle moves in a curve; when the speeds of the reduction motors 23 on the left and right sides are the same and in opposite directions, the vehicle turns in place.

[0050] When the vehicle is traveling on a complex and uneven road surface, the front wheel 31 will rise and fall, driving the movable wheel suspension 2 to rotate around the movable shaft 14 along the vehicle body frame 1. At the same time, the opening of the front tooth package fixing plate 26 on the movable wheel suspension 2 will be limited by the limit plate 15 on the vehicle body frame 1. Due to the existence of the movable shaft 14, the rotation of the movable suspensions on the left and right sides does not affect each other. At this time, the front wheel 31 and the rear wheel 32 fixed on the movable wheel suspension 2 will rise and fall with the road surface and realize the simultaneous landing of the four wheels, keeping the shelf 4 relatively stable and achieving a terrain adaptive effect.
