Description

Mechanical parking mechanism for three-wheeled vehicle

Technical Field

The utility model relates to an electric motor car, motorcycle technical field refer in particular to a machinery parking mechanism for tricycle vehicle.

Background

By two-front-wheel vehicle is meant a new type of vehicle having two steered front wheels and at least one driven rear wheel. In the prior art, a double-front-wheel vehicle generally adopts a principle of parallelogram multi-shaft multi-rod linkage, two front wheels in charge of steering are connected with a head vertical pipe at the front end of a frame by a unique tilting device, and the tilting and bending as the traditional two-wheel locomotive are realized by a changeable parallelogram structure. Unlike a triangle, a parallelogram has instability, can deform under the action of an external force, and two opposite sides always keep a parallel state during deformation. By utilizing the principle, two front wheels of the double-front-wheel vehicle can roll left and right greatly without being limited by a frame and a shock absorber when turning, and three wheels of the whole vehicle are always in contact with the ground, so that the vehicle generates enough positive pressure on the ground through the wheels to balance the centrifugal force applied to the vehicle, and the capability of resisting the side turning of the vehicle when turning is effectively improved.

Although the swing device of the parallelogram structure can improve the stability and the safety of the double-front-wheel vehicle when the double-front-wheel vehicle runs, particularly when the double-front-wheel vehicle turns, when the double-front-wheel vehicle needs to be parked and parked, the swing device of the double-front-wheel vehicle is easy to roll leftwards and rightwards due to the instability of the parallelogram, the whole vehicle body is difficult to keep a vertical state, and the stability of the double-front-wheel vehicle when the double-front-wheel vehicle is parked cannot be ensured.

Therefore in prior art, fix the wheel through increasing parking mechanism usually, thereby when realizing the vehicle parking, also can remain stable, like the chinese utility model patent, the patent number is CN207208339U, a two front wheel electric motor cars of a public disclosure, motorcycle parking locking structure, through pushing down the handle, it drives the afterbody motion of parking piece to act as go-between, make the parking piece rotate round first lock bracket through pin joint portion, lock portion rises and supports the lower extreme of linkage, linkage is transversely fixed, can't realize the swing, so whole independent suspension is just fixed, reach the effect of parking.

The above scheme realizes the effect of parking through the fixed independent suspension system, but because the damping device on the wheel still can be moved, can lead to the parking unstability, therefore still need to improve this structure further.
