Description

A multi-section adjustable suspension for all-terrain vehicles

technical field

The invention relates to a device for an all-terrain vehicle, in particular to a device for controlling the suspension height by a single-chip microcomputer.

Background technique

The predecessor of the modern all-terrain vehicle (ATV) originated from a locomotive with three wheels and low pressure tires. At first it was only a vehicle designed for off-road racing, and later it gradually became a racing car, a utility vehicle, a family recreational vehicle, and so on. With the popularity in markets such as the United States, the locomotive has changed from three wheels to four wheels. As four-wheel vehicles became the main form of all-terrain vehicles, four-wheel drive ATV vehicles also developed.

An all-terrain vehicle refers to a vehicle that can travel on any terrain, and can walk freely on terrain where ordinary vehicles are difficult to maneuver. A type of vehicle has multiple uses and is not limited by road conditions, but the fixed suspension height of the all-terrain vehicle is still insufficient in extreme off-road outdoors, so a device with multi-stage adjustable suspension is needed.

Contents of the invention

The object of the present invention is to provide an all-terrain off-road vehicle with multi-stage height-adjustable suspension. To solve the problems raised in the background technology above.

To achieve the above object, the present invention provides the following technical solutions:

A multi-section adjustable suspension for an all-terrain vehicle, which is characterized by a push rod fixed lug, a front suspension upper cantilever, a front suspension lower cantilever, a shock absorber, a rocker arm, a rocker arm lug, a steering knuckle, a wheel hub, Tires, electro-hydraulic push rods, single-chip microcomputer control components and main body frame, wherein the axis of the electro-hydraulic push rod and the axis of the shock absorber are in the same plane, and the stroke amount of the electric push rod is controlled by the memory program of the single-chip microcomputer control component; The end pushes the fixed point above the rocker arm to make the rocker arm and the connection point of the rocker arm hanger form a fixed axis rotation, the fixed point above the shock absorber is connected to the connection point below the rocker arm, the rocker arm rotates to push the shock absorber downward, and the shock absorber The lower end is connected with the fixed point of the lower cantilever of the suspension, and the lower cantilever and the upper cantilever are connected with the steering knuckle to form a linkage member. When the shock absorber pushes the lower cantilever to move down, the height of the suspension is changed.

The rocker arm is connected with the shock absorber and the electric push rod, the shock absorber is connected with the lower suspension arm of the suspension, and the lower suspension arm and the upper suspension arm are connected with the steering knuckle to form a linked adjustable component.

The suspension height is changed by controlling the push rod stroke of the electro-hydraulic push rod through the memory program of the single-chip microcomputer control element.

The beneficial effects of the present invention are:

1. Simple structure, compact and reliable, easy maintenance;

2. Adjust the suspension height according to road conditions;

3. The suspension height cannot be adjusted when the vehicle is driving, which improves equipment safety and reduces the occurrence of traffic accidents;

4. The material of the rocker arm is 4130# steel, which improves stability and impact resistance, and the material of the push rod fixing lug is carburized 45# steel, which has good wear resistance and impact resistance;

5. Low manufacturing cost, suitable for large-scale production and civilian use.

Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Please refer to Fig. 1 to Fig. 2, the present invention is realized like this: a kind of multi-stage adjustable suspension for all-terrain off-road vehicle, comprises push rod fixing lug 1, electrohydraulic push rod 2, rocking arm 3, rocking arm Lifting lug 4, shock absorber 5, suspension upper cantilever 6, steering knuckle 7, suspension lower cantilever 8, wheel hub 9, tire 10, single-chip microcomputer control element 11 constitute.

The single-chip microcomputer control element 11 controls the push rod stroke of the electro-hydraulic push rod 2, the electro-hydraulic push rod 2 is connected with the rocker arm 3, the rocker arm 3 is connected with the rocker arm lug 5, and the electro-hydraulic push rod 2 pushes the rocker arm 3, The rocker arm lug 4 rotates at a fixed axis, the fixed point at the lower end of the rocker arm 3 is connected to the connection point at the upper end of the shock absorber 5, the lower end of the shock absorber 5 is connected to the lower suspension arm 8, and the lower suspension arm 8 and the upper suspension arm 6 are connected to the The steering knuckles 7 are connected to each other to form a linkage member, and the shock absorber 5 pushes the lower boom 8 to move downward, thereby adjusting the height of the suspension.

For the multi-stage adjustable suspension of the all-terrain vehicle, start the single-chip microcomputer control element 11 for suspension height adjustment, and then the electro-hydraulic push rod 2 pushes the rocker arm 3, and the rocker arm 3 rotates around the rocker arm lug 4 to drive the shock absorber 5 The suspension arm 8 moves obliquely to change the suspension member, thereby adjusting the suspension height.

For the multi-stage adjustable suspension of the all-terrain vehicle, if the height of the suspension is adjusted when the vehicle is running, the single-chip microcomputer control element 11 will automatically disconnect the circuit of the electro-hydraulic push rod 2 to reduce traffic accidents.

The multi-stage adjustable suspension of the said all-terrain vehicle can be pre-programmed in the single-chip control element 11 to control the electro-hydraulic push rod 2 to adjust the suspension height by the single-chip control element 11.

The multi-stage adjustable suspension of the all-terrain vehicle only needs the engine to provide power, and no external power supply is needed, which saves more space.
