Problems solved by technology

However, due to the addition of two wheels, the friction with the ground increases, and the increase in the mass of the frame leads to an increase in the pedaling force, which increases the physical exertion of the rider. Although there are also electric power-assisted bicycles, electric vehicles are Faced with a series of inconveniences caused by the exhaustion of battery power, it is necessary to provide a four-wheeled bicycle that can realize both pedal transmission and electric vehicle transmission

Abstract

The invention provides an improved quadricycle. The improved quadricycle comprises a frame assembly which comprises a keel and a front axle component, one end of the keel is fixedly connected with the front axle component, a pedal drive component coordinates with an electric power-assisted component, an auxiliary assembly comprises a seat which is fixed to the keel at the rear of a first chain wheel component, and a second bearing sleeve is fixed to the auxiliary component; two rolling wheels are rotatably arranged at the two ends of the front axle component, one rolling wheel is fixedly connected with an outer rotor of a motor, and the other rolling wheel is fixedly connected with one end of the rotating shaft. According to the improved quadricycle, by making the electric power-assisted component coordinate with the pedal drive component, the mutual matching effect of the electric power-assisted component and the pedal drive component is achieved, and the electric power-assisted component and the pedal drive component are fixed together in a matched mode through a rear axle, the keel and a motor mounting plate.

Description

technical field [0001] The invention relates to a four-wheel bicycle, in particular to an improved four-wheel bicycle. Background technique [0002] Because of the particularity of its structure, four-wheeled bicycles have significantly improved safety and stability compared with two-wheeled bicycles. However, due to the addition of two wheels, the friction with the ground increases, and the increase in the mass of the frame leads to an increase in the pedaling force, which increases the physical exertion of the rider. Although there are also electric power-assisted bicycles, electric vehicles are Faced with a series of inconveniences caused by the depletion of battery power, it is necessary to provide a four-wheeled bicycle that can realize pedal transmission and electric vehicle transmission. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the problems in the prior art. The present invention provides ...
