Self-balancing type chassis for four-wheel vehicle

Abstract

The invention relates to a self-balancing type chassis for a four-wheel vehicle, which is suitable for small vehicles, electric four-wheel vehicles or manpower four-wheel bicycles. The self-balancing type chassis for the four-wheel vehicle comprises wheels, front axles, rear axles, a frame, balanced beams, anti-vibrating springs and extension arms, wherein the two longitudinal sides of the frame are respectively provided with an extension-arm fitting seat, and a slide guide is arranged in the extension-arm fitting seat; the extension arm is provided with an axis pin, the two ends of the axis pin are provided with limit joints, and the extension arm is arranged in the slide guide of the extension-arm fitting seat by the limit joints so as to make the extension arm slide and swing upwards and downwards; the anti-vibrating spring is arranged between the upper part of the extension arm and the extension-arm fitting seat; the rear ends of the two extension arms are respectively connected with a universal joint, and the front ends of the two extension arms are respectively connected with the front axles and the rear axles by lifting lugs; both the front part and rear part of the frame are provided with the balanced beams, the balanced beams are hinged with the base frame, the two ends of the balanced beam are respectively provided with the universal joints, and the universal joints are hinged with the ends of the balanced beams; and the two ends of the front axles and the rear axles are provided with the wheels.

Description

technical field [0001] The invention relates to a self-balancing four-wheel vehicle chassis, which is suitable for small cars, electric four-wheel vehicles or human-powered four-wheel vehicles. Background technique [0002] At present, the common anti-vibration structures of automobiles are vibration-damping springs and spring steel sheets. When one of the wheels is lifted up by a raised object on the ground, only the corresponding vibration-damping springs and spring steel sheets of the wheel are used for vibration reduction, and the force cannot be transmitted to the vehicle. On the other side of the wheel, the chassis cannot be automatically balanced, which will cause uneven force, make passengers feel uncomfortable, or cause the vehicle to roll over. There are also reverse spring steel used as conduction, but because it only has the effect of absorbing force, It does not have the function of conduction force, so the vibration reduction effect is not obvious.
