Embodiment Construction

[0017] Such as figure 1 As shown, the liftable suspension system proposed by the present invention consists of a suspension spring 1, a load-bearing shock absorber 2 (patent number: 200720094724.2; 200710056382.x), an accumulator 3, a guide mechanism 4, a connecting pipe 5, Composed of electric oil pump 6, oil storage tank 7, and isolator 8, it is characterized in that: the electric oil pump 6, oil storage tank 7, and isolator 8 form a high-pressure oil source. When the electric oil pump 6 has no pressure, the floating in the isolator 8 The piston 9 is at the highest position, correspondingly the suspension system is at the lowest position; when the electric oil pump 6 is started, the oil in the oil storage tank 7 is pumped to the isolator 8, pushing the floating piston 9 to the load-bearing shock absorber 2 of each wheel Filled with oil, the suspension system has different height lifts according to the pressure of the pump oil. When the vehicle body height needs to fall back...

Abstract

The invention relates to a technology for lifting a suspension. The invention provides a simple and convenient method so as to improve the obstacle performance of various vehicles with arbitrary suspension form under the condition of uneven road. Compared with the general hydraulic lifting suspension system, the technology is characterized in that a high-power oil (air) pump and an actuating cylinder are not required, and the mounted type shock absorber (patent) with structure and size basically identical with the structure and size of the prior shock absorber replaces the ordinary shock absorber and the lifting cylinder. As the mounted type shock absorber only bears small part of dead load, the carrying area is very small, and the required lifting power source is also small; as for the vehicle with power steering, the suspension can be lifted by using the oil source of the power steering; and even the suspension can be lifted by using a manual (for example, treading) master cylinder. The invention has the characteristics that the invention is especially suitable for being modified on the existing vehicle with suspension structure, and has high applicability and low cost.

Description

technical field [0001] The invention relates to liftable suspension technology. It provides an easy way to lift through the shock absorber to improve the obstacle clearance ability of all types of vehicles with any suspension type in uneven road conditions. Background technique [0002] Improving the ground clearance of the vehicle through the lifting system of the suspension is an effective measure to improve the vehicle's ability to overcome obstacles. Usually this kind of car performance is achieved by relying on the height control device of the car's oil-pneumatic suspension or air suspension. The structure of this system is relatively complicated, and it is quite different from the common metal spring suspension system in structure, and the cost is high. It is usually only used on high-end off-road vehicles and a small number of high-end cars and luxury buses. Contents of the invention [0003] The invention provides a simple method for improving the obstacle-surmou...
