Reverse tricycle with switchable driving modes

Abstract

The invention discloses a reverse tricycle with switchable driving modes, the tricycle comprises a deflection and steering mechanism, a rear section tricycle frame, a driving wheel and two front wheels, the deflection and steering mechanism comprises a main beam, a left front arm assembly and a right front arm assembly, the left front arm assembly and the right front arm assembly are symmetrically arranged on the two sides of the main beam, and the left front arm assembly comprises a left upper rocker arm, a left lower rocker arm and a left steering knuckle structure; the right front arm assembly comprises a right upper rocker arm, a right lower rocker arm and a right steering knuckle structure, the main beam is of a hollow structure with a mounting hole, and a damping device penetrates through the mounting hole; the left upper rocker arm, the left lower rocker arm, the right upper rocker arm and the right lower rocker arm are of split structures; the main beam is connected with the rear section tricycle frame through a plurality of pile heads. The left rocker arm and the right rocker arm are coaxially hinged to the main beam respectively, full parallelism can be achieved during turning or inclining, vehicle driving is more stable, and the left rocker arm and the right rocker arm are independent gravity center deflection systems which do not interfere with each other; meanwhile, due to the left front arm assembly and the right front arm assembly which are in universal structural design, the production cost is greatly reduced.

Description

technical field [0001] The invention relates to a vehicle, in particular to a reverse tricycle with switchable driving modes. Background technique [0002] Reverse tricycle refers to a relatively special product with two wheels in the front steering wheel system. Compared with the two-wheeled vehicle, one more wheel is in contact with the ground. The stability advantage greatly reduces the possibility of the rider slipping and falling, and the driving safety is greatly improved compared with the two-wheeled vehicle in the complex terrain environment. [0003] In the reverse tricycle of the prior art, in order to make the front steering wheel train comprising two wheels adapt to the complex terrain environment, so that the left and right wheels will not tilt the car body when the height of the ground in contact with the left and right wheels is inconsistent, generally all adopt A shock absorber with a horizontal layout, the two ends of the shock absorber are respectively hin...
