Description
(1) technical field
The utility model relates to a kind of automobile suspension system, in particular to a kind of automobile hydraulic suspension jacking system.
(2) background technology
Automotive suspension is the general designation of the elastic connecting device between vehicle frame (or vehicle body) and the axletree (or wheel).Its effect is elastomeric connection vehicle bridge and vehicle frame (or vehicle body), so as to the impulsive force that vehicle in the buffering enforcement is subjected to, guarantee that goods is intact and personnel are comfortable, decay is because the vibration that elastic system brought, make the stable posture of maintenance in the running car, improve road-holding property.In case the suspension system parameter of domestic automobile is set at present, then vehicle just can't be adjusted in driving process, and suspension property is restricted.Along with the development of Eltec and pressure technology, used both at home and abroad a kind of pneumatic suspension system on the high-grade car gradually, make this problem obtain solving preferably.The pneumatic suspension system has the characteristics of traditional suspension, can regulate its parameter in automobile is advanced again, and it is by air cylinder control suspension bar, thereby vehicle body can be raise or reduce.When galloping, can reduce height of car like this,, when on rugged road, travelling, when particularly exercising on dirt road, the hill path, improve vehicle body, to improve obstacle climbing ability by air cylinder to reduce windage and road-holding property.Yet air pressure suspension volume ratio is bigger, and air cylinder thrust is little comparatively speaking, so need larger-diameter air cylinder, volume will be bigger than normal, and be subjected to the restriction of pressure system self, its manufacturing cost height, technical requirements height, external control element is many, and when not adopting the metal buffer spring simultaneously, in case et out of order, vehicle can't travel, its range of use is subjected to certain limitation, and general car is not assembling basically.
(3) summary of the invention
The utility model hangs because of the technical requirements height at present air pressure, cause its cost height, volume big, the defective of performance reliability difference, the automobile hydraulic suspension jacking system of provide that a kind of volume is little, low cost of manufacture, dependable performance, control element are few, being convenient to assemble.
The technical solution adopted in the utility model is:
The utility model automobile hydraulic suspension jacking system, comprise the bumper pipe link, comprise that also Hydraulic Pump and piston/cylinder and described shock absorber pipe link tail end are by the fixing plunger-type cylinder of check screw, wherein, in the hydraulic cylinder body side, its fixed end is fixed on the axletree corresponding to the plunger-type cylinder control port of car rear suspension; In the hydraulic cylinder body bottom, its fixed end is fixed on the vehicle frame corresponding to the plunger-type cylinder control port of front suspension; Preceding plunger-type cylinder group links to each other with above-mentioned Hydraulic Pump by check valve with back-plunger formula hydraulic actuating cylinder group, is provided with oil return pipe between above-mentioned check valve and above-mentioned hydraulic actuating cylinder group, and oil return pipe is provided with electromagnetic valve.
Above-mentioned automobile hydraulic suspension jacking system, described Hydraulic Pump oil outlet pipe is provided with pressure relay.
The utility model automobile hydraulic suspension jacking system, it breaks through the pneumatic suspension system replaces original suspension with pneumatic suspension mode, but on the basis of original suspension, add hydraulic lift, be similar to the serial connection in the electricity, but be mechanical device because of it, principle is incomplete same again, if added like this hydraulic lift breaks down, such as the hydraulic pump works mal, oil feeding line goes wrong, perhaps hydraulic actuating cylinder goes wrong, and can guarantee at least that all automobile still can normally use.
The plunger-type cylinder of the hydraulic lift that the utility model increases is that its piston/cylinder and described shock absorber pipe link tail end are fixed by check screw, the respective fixation end of original bumper pipe link replaces with the fixed end of above-mentioned hydraulic actuating cylinder, because of the front and back bumper is provided with different, the selection of its plunger-type cylinder is also different, in the hydraulic cylinder body side, its fixed end is fixed on the axletree corresponding to the plunger-type cylinder control port of car rear suspension; In the hydraulic cylinder body bottom, its fixed end is fixed on the vehicle frame corresponding to the plunger-type cylinder control port of front suspension; And the utility model is considered the structure of front shock absorber, and plunger-type cylinder adopts and does coaxial setting with spring, makes its more compact structure, also is convenient to the fixing of hydraulic actuating cylinder fixed end.
The utility model automobile hydraulic suspension jacking system adopts hydraulic efficiency gear to replace original pneumatic shuttle, compact conformation, and the utility model has only increased hydraulic actuating cylinder with respect to original draft hitch comparatively speaking, its control system is then corresponding to have increased a check valve, electromagnetic valve and Hydraulic Pump and fuel tank and respective line, used element is few, and it directly can directly assemble on original suspension system, its design, assembling, control are simple, low cost of manufacture.Because intermediate link is few, so reliable working performance, fault rate is low.
