Independent type steering and suspension fork system of three-wheeled vehicle

Abstract

The invention discloses an independent type steering and suspension fork system of a three-wheeled vehicle. The independent type steering and suspension fork system comprises a vehicle frame, whereina rocker arm is hinged to the front end of the vehicle frame; a damping system is arranged between the rear part of the rocker arm and the vehicle frame; a front suspension assembly allowing a front wheel of the three-wheeled vehicle to mount is rotatably arranged at the front end of the rocker arm; a steering machine is also mounted at the front end of the vehicle frame, and a steering connectingrod system is connected to the steering machine; and the steering connecting rod system is connected with the front suspension assembly. According to the independent type steering and suspension forksystem disclosed by the invention, a steering system and a suspension fork system are completely independent and are not mutually influenced, so that the problem that a steering column shaft and a steering bearing of a conventional steering system are invalid at an early stage is solved, the influence on a steering wheel is avoided, the vibration of the steering wheel is reduced, and the travelling comfortableness is improved; the independent type steering and suspension fork system is compact in structure; the mounting space is saved; early-stage invalidation including oil leakage, breakageand the like of damping elements is avoided; and different requirements used during light loading and heavy loading can be met, and the smoothness is good.

Description

technical field

[0001] The invention relates to a three-wheel vehicle technology, in particular to an independent steering and suspension system for a three-wheel vehicle. Background technique

[0002] At present, all three-wheeled vehicles use the front fork type front suspension mechanism. The steering system and the front suspension system are integrated into one piece, interacting and restricting each other, and there is a problem of large steering force; There is too much space in the cab, resulting in a small space inside the cab. The steering gear of the steering system is fixed on the cab. Larger makes the front slant beam that fixes the front fork assembly easy to break. At the same time, for this kind of structure, the front wheel load is transmitted to the frame through the steering column shaft and steering bearing, so the steering column shaft and steering bearing are prone to early failure, and the shock absorbing elements used in the front suspension system a...
