Three-wheel swing rigid suspension mechanism

Abstract

The invention relates to a three-wheeled swinging rigid suspension mechanism which structurally comprises a left swinging arm, a right swinging arm, a left universal wheel, a right universal wheel, a steering wheel support, a steering wheel and a hydraulic steering mechanism. The left swinging arm is connected with a vehicle frame through a left swinging arm hinge pin, the left universal wheel is hinged to the outer side end of the left swinging arm, the right swinging arm is hinged to the right end of the left swinging arm through a right swinging arm hinge pin, the right universal wheel is hinged to the outer side end of the right swinging arm, a left limiting block and a right limiting block are arranged above the left universal wheel and the right universal wheel, the left limiting block and the right limiting block are used for limiting the jumping quantity of the universal wheels, the steering wheel is installed on the steering wheel support, the steering wheel support is perpendicularly hinged to the right swinging arm, the hydraulic steering mechanism is connected between the right swinging arm and the steering wheel support, the steering wheel support is driven by the hydraulic steering mechanism to be steered, then the steering wheel is steered, and therefore steering of a vehicle is achieved. According to the three-wheeled swinging rigid suspension mechanism, the stress proportion of the wheels is unchanged, the stress of the steering wheel is largest, therefore, the attachment performance of the steering wheel to the ground is improved, steering is stable, and traveling is stable.

Description

technical field [0001] The invention relates to a suspension mechanism of a motor vehicle, in particular to a three-wheel swing rigid suspension mechanism. Background technique [0002] Existing industrial three-wheel motor vehicles are generally supported by a single wheel on one side and two wheels on one side. The three wheels are all rigid suspensions. It is not flexible enough, and it can't even turn when it is serious. The support range of the three-wheel support is small, and the driving stability of the vehicle is poor; when climbing a slope, the car body of the one-side wheel is easy to touch the ground, and the passability is poor, which affects the steering performance and limits the application range of the three-wheel vehicle. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a three-wheel swing rigid suspension mechanism with flexible steering, good passability and good stabil...
