Problems solved by technology

However, whether it is an electric tricycle or a motor tricycle, its tricycle frame adopts an integral structure. When turning, due to careless operation or excessive speed, it is easy to cause the tricycle to be subjected to inertial centrifugal force, causing the outer rear wheel of the tricycle to leave the ground. Even lead to the risk of overturning, the safety of the vehicle is greatly reduced, and there is a great potential safety hazard

Abstract

The invention discloses a tricycle frame, which comprises a main frame, an auxiliary frame and a saddle, wherein the main frame comprises a front girder, a handle bar, a front fork and a front wheel; the auxiliary frame comprises a rear girder, a rear wheel and a rear saddle; the main frame and the auxiliary frame are connected through a torsion bar component between the front girder and the rear girder; the torsion bar component comprises a transverse axle, a longitudinal axle, and a front bear and a rear bearing which are installed on the longitudinal axle; and the transverse axle is fixedly installed at the front end of the rear girder, an axle sleeve is sleeved on the transverse axle and is fixedly connected with the rear bearing, and the front bearing is fixedly connected with the front girder. The tricycle frame disclosed by the invention has the advantages of simple structure, convenience for operation, strong practicability, stable driving, safety and reliability; and during turning, the torsion bar component can enable the main frame and the auxiliary frame to generate relative rotation with a certain angle in the axial direction to balance out a sideway force generated during turning and to prevent side overturn of a tricycle during driving, so as to guarantee the stability of the entire tricycle and the driving safety, guarantee safe turning and driving under arbitrary speeds and turning angles and improve the stability during driving and turning.

Description

technical field [0001] The invention belongs to the technical field of vehicles, in particular to a tricycle frame. Background technique [0002] With the development of society and the improvement of living standards, people's requirements for transportation and means of transportation are gradually increasing. After the appearance of electric tricycles, the coexistence of electric tricycles and motor tricycles has formed in the market. However, whether it is an electric tricycle or a motor tricycle, its tricycle frame adopts an integral structure. When turning, due to careless operation or excessive speed, it is easy to cause the tricycle to be subjected to inertial centrifugal force, causing the outer rear wheel of the tricycle to leave the ground. Even cause the danger of overturning, the driving safety of the vehicle is greatly reduced, and there is a great potential safety hazard. Contents of the invention [0003] The object of the present invention is to provide ...
