In addition, different types of return springs 42 can be selected to adapt to different steering requirements of the vehicle, that is, the swinging amplitude of the pendulum rod 41 can be adjusted by replacing different types of springs, thereby controlling the inclination of the vehicle body 1, and the structure design is more reasonable. In addition, in the process of turning the vehicle at low speed, the cable 53 and the return spring 42 can also tighten the swing rod 41 to limit the movement of the swing rod 41, thereby limiting the deflection of the dual-wheel suspension structure 3 connected to the swing rod 41. Safety accidents such as overturning caused by excessive deflection of the double-wheel suspension structure 3 during the steering process are prevented. When the vehicle runs straight at high speed, the cable 53 and the return spring 42 will not impose excessive restrictions on the swing rod 41, and the two-wheel suspension structure 3 can deflect relatively freely, thereby adapting to the ups and downs of the road surface, reducing the vibration of the vehicle and improving the ride. experience.

The manual three-wheeled motorcycle provided in this embodiment includes a body 1, a single-wheel suspension structure 2, a double-wheel suspension structure 3, an adjustment assembly 4 and a direction control device 5; The single-wheel suspension structure 2 of the wheels 21 and the double-wheel suspension structure 3 with rear wheels 31 are provided on the vehicle body 1 with an adjustment assembly 4 connected to the double-wheel suspension structure 3 and the steering of the front wheels 21 and acting on the adjustment assembly. The direction control device 5 on the 4, so that when the front wheel 21 is turned, the adjustment assembly 4 can be pulled through the cable 53 in the direction control device 5, so that the adjustment assembly 4 drives the two-wheel suspension structure 3 to deflect toward the opposite side of the steering direction , so that the body 1 is inclined toward the steering direction side, so that the overall force of the vehicle is more balanced, the damage to the structural components is prevented, the service life of the vehicle is prolonged, and the occurrence of safety accidents such as rollovers is avoided. The counterweight makes the vehicle more stable and more conducive to the use and promotion of the vehicle.

The above are only preferred embodiments of the present invention, and are not intended to limit the embodiments and protection scope of the present invention. For those skilled in the art, they should be aware of the equivalent replacement and Solutions obtained by obvious changes shall all be included in the protection scope of the present invention.
