In addition, different steering requirements of the vehicle can be met by selecting different types of the return springs 42, and the swing amplitude of the swing rod 41 can be adjusted by replacing different types of springs, so that the inclination of the vehicle body 1 is controlled, and the structural design is more reasonable. In addition, in the process of low-speed steering of the vehicle, the pull cable 53 and the return spring 42 can also tension the swing rod 41 to limit the action of the swing rod 41, so that the deflection amount of the double-wheel suspension structure 3 connected with the swing rod 41 is limited, and safety accidents such as overturning and the like caused by excessive deflection of the double-wheel suspension structure 3 in the steering process are prevented. When the vehicle runs straight at a high speed, the inhaul cable 53 and the return spring 42 cannot generate overlarge limitation on the swing rod 41, and the double-wheel suspension structure 3 can deflect freely, so that the double-wheel suspension structure adapts to the fluctuation of the road surface, reduces the vibration of the vehicle, and improves the riding experience.

The manual motor tricycle provided by the embodiment comprises a tricycle body 1, a single-wheel suspension structure 2, a double-wheel suspension structure 3, an adjusting assembly 4 and a direction control device 5; a single-wheel suspension 2 with a front wheel 21 and a double-wheel suspension 3 with a rear wheel 31 are respectively arranged at the front end and the rear end of the vehicle body 1, and an adjusting component 4 connected to the double-wheel suspension structure 3 and a direction control device 5 for controlling the front wheel 21 to turn and acting on the adjusting component 4 are arranged on the vehicle body 1, so that, when the front wheels 21 are steered, the adjusting assembly 4 can be pulled by the cable 53 in the direction manipulation device 5, so that the adjusting assembly 4 deflects the two-wheeled suspension 3 towards the opposite side of the steering direction, so that the vehicle body 1 inclines towards one side of the steering direction, the whole stress of the vehicle is more balanced, the damage of structural components is prevented, the service life of the vehicle is prolonged, the safety accidents of rollover and the like are avoided, meanwhile, the counterweight of the vehicle is also increased, so that the stability of the vehicle is higher, and the vehicle is more beneficial to use and popularization.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
