Background

Inverted tricycles with two wheels at the front end and one wheel at the rear end have been widely popularized in the market. Toyota i-road reverse tricycle adopts rear wheel steering, and the steering mode has uncomfortable feeling for the driving experience. The riding habit of most people is front wheel steering, which is analyzed from the geometrical aspect of tracking, and rear wheel steering is not good for human body sensory adaptation. At present, inverted tricycles adopting front wheel steering exist in the market, but the inverted tricycles have no optimized design for the balance structure of a vehicle body.

Chinese utility model patent CN201320203320.8 discloses a three-wheeled solar vehicle frame that can heels in turning, the main weak point that this frame exists is: 1. a balance adjusting mechanism is not arranged, and the automobile body cannot be well balanced in the driving process. 2.

But its mechanical part is still in the following problem: 1. also, a mechanical structure for adjusting the balance of the vehicle body is not provided, and the balance effect on the vehicle body is not good. 2. The bottom end of the shock absorber assembly is connected with the balance lower A arm, on one hand, the inner inclination angle of the shock absorber assembly is too large, when the two wheels are stressed differently, the deformation of a parallelogram formed by the balance upper A arm and the balance lower A arm is nonlinear, the feedback of the tail section of the shock absorber assembly is weaker than that of the first section of the shock absorber assembly (ideally, the feedback of the tail section of the shock absorber assembly is stronger than that of the first section of the shock absorber assembly), and the shock absorption effect is poor; on the other hand, the shock absorber assembly needs to penetrate through the balance upper A arm to be connected with the balance lower A arm, and the installation space of the shock absorber assembly is limited by the balance upper A arm, so that the adjustment installation range of the back inclination angle is limited greatly, and the adjustment of the back inclination angle is not facilitated. 3. The auxiliary frame is also arranged, and the space occupied by the auxiliary frame is large, so that the volume of the whole vehicle is large. 4. The transmission device adopts a structure of a gear and a chain, namely, the stepping motor is driven by the gear and the chain, and is an open type lubricating structure, and the defects of large looseness and large abrasion exist.
