Abstract

The invention discloses a riding electric tricycle which comprises a front steering wheel, a middle steering wheel and a rear driving wheel, wherein three wheels are combined with a multidirectional triangular frame and are arranged in a straight line in a road row mode. A steering linkage mechanism is arranged between the front steering wheel and the steering wheel, so that the steering linkage mechanism deflects at different angles in the steering process and keeps synchronization with the driving direction. The vehicle is equipped with a brake synchronizing mechanism, and the three wheels share the braking force evenly through a single braking source. The three wheels have the same center height, the same wheel diameter and the same wheel base, and form a supporting structure with the force of the tripod. When the vehicle passes through a low-lying road surface, the load is shared by the middle and rear wheels to realize stepped shock absorption. The invention is based on the principles of three points and one line and the force of ancient cooking vessel, which can obviously improve the ground grabbing force, sideslip preventing capability and running stability of the whole bicycle and effectively improve the riding safety and comfort while keeping the flexibility of the bicycle.

Description

Electric tricycle rides Technical Field The application relates to the technical field of vehicles, in particular to a riding electric tricycle. Background With the popularization of new energy vehicles, riding electric vehicles have become an indispensable vehicle for home commuting and logistics distribution industries (such as takeaway distribution). However, the existing solutions still have the following drawbacks: (1) The safety limitation of the two-wheeled electric vehicle is that the traditional two-wheeled electric vehicle has limitations on braking performance and driving comfort. (2) The existing tricycles have the defect of poor flexibility because of the fact that the regular tricycles or the reverse tricycles exist in the market, and the vehicle body structure is wider, so that the trafficability is poor due to overlarge volume when the tricycle runs on a narrow road or a congested road section. This makes it impossible for the user to achieve convenience and flexibility similar to a two-wheeled vehicle while pursuing stability. (3) The shock absorption and braking synergistic effect is poor, namely when the existing small electric vehicle faces uneven or low-lying road surfaces, the problem of distribution of supporting points often causes severe falling feeling or bumpy feeling of the vehicle body, and riding comfort is affected. Meanwhile, the braking force is often not distributed uniformly among the wheels, and the phenomenon of locking and slipping of a single wheel set or insufficient braking force is easy to occur.
