[0002] Go-karts are usually equipped with an independent electric motor, which is installed at the rear of the go-kart. The electric motor transmits power to one or two rear wheels through a transmission device, such as a chain, a belt or a direct mechanical connection. The driver controls the direction of travel of the vehicle through the steering wheel, and the braking system usually acts on the rear wheels and is controlled by the driver through the brake pedal. When the go-kart turns, the inner wheel and the outer wheel need to take different arcs, and the traditional single motor drives the two rear wheels at the same time through the transmission shaft, resulting in the same rotation speed of the inner and outer wheels when turning. Such a design makes the actual travel path inconsistent with the actual rotation path length of the wheel, thereby affecting the stability and maneuverability of the go-kart when turning. The problem to be solved by the utility model is that the existing go-kart uses a single motor to drive the two rear wheels at the same time through the transmission shaft, resulting in the same rotation speed of the inner and outer wheels when turning.
