Description
Technical field
The present invention relates to a kind of auto parts and components, especially vehicle shock absorber belongs to automobile manufacturing field.
Background technique
Known vibration damper is the important component of the spring suspension system of automobile.Absorb the suspension elastic energy of automobile up-down vibration by the hydraulic oil damping function of vibration damper working medium, realize reducing under steam the purpose of automobile vibration intensity, be characterized in: compression hydraulic oil forms the closed-loop path of flowing back and forth to rod chamber again from the rod chamber to the rodless cavity, have the damping hole of two directions and the valve that twocouese is opened on the piston at least.Because the piston in the vibration damper constantly moves up and down, produce heating and dissipation energy makes that simultaneously the working life of telescopic shock absorber is shorter.
Summary of the invention
The present invention is a kind of refrigerating shock absorber that absorbs vibrational energy, outer portion connecting structure: hanger links to each other with vehicle frame with spring suspension system respectively with the piston rod thread end, and input end, output terminal link to each other with low voltage terminal, the high voltage terminal of compressor in the motorcar air conditioner system respectively; Internal structure is: refrigeration agent is as working medium; The cylinder that three coaxial lines are arranged, one is dust-proof cover, and one is clutch release slave cylinder, and one is gas-storage cylinder, is provided with two holes on the gas-storage cylinder, has welded first joint, second joint respectively, connects first one-way valve, second one-way valve again respectively; Piston rod guide has pipe hole; Gas-storage cylinder is connected with piston rod guide, clutch release slave cylinder seat respectively with clutch release slave cylinder coaxial line two ends, forms the gas storage district; Increase a pipeline in the gas storage district, an end of pipeline inserts in the pipe hole of piston rod guide, and the other end inserts and leads to second one-way valve in second joint; A piston that second damping hole is arranged is set in clutch release slave cylinder, by second valve closing and opening, band seal ring piston rod; Being provided with one at the clutch release slave cylinder seat has first damping hole, by first valve closing and opening; First one-way valve is connected in parallel as the low voltage terminal of the compressor in input end and the motorcar air conditioner system, second one-way valve is connected in parallel as the high voltage terminal of the compressor in output terminal and the motorcar air conditioner system, use same set of automotive air-conditioning system, the pressure of two kinds of one-way valves is set according to the pressure of the compressor in the automotive air-conditioning system, the pressure that backs down of first one-way valve is set to 0.1-0.8Mpa, the pressure that backs down of second one-way valve is set to 0.8-2.5Mpa, uses refrigeration oil lubricated.
The working principle of summary of the invention is that automobile is exercised on highway, because the out-of-flatness of road causes the up-down vibration in the automobile running, causes that clutch release slave cylinder inner carrier of the present invention moves up and down:
(1) (see figure 1) when piston stroking upward, the rodless cavity inner volume increases, pressure is lower than the gas pressure in the gas storage district, suck the low voltage terminal refrigeration agent of compressor in the automotive air-conditioning system, refrigerant gas just backs down first one-way valve and enters the gas storage district, by first damping hole of clutch release slave cylinder seat, back down first valve and enter rodless cavity.The refrigerant gas of rod chamber forms high pressure-temperature gas by compression, the second valve pressurized is closed, form the vibration damping air cushion and reduce automobile vibration intensity, the part refrigerant gas leads to the pipe hole of piston guide seat, pass through pipeline, lead to second joint, back down second one-way valve, enter compressor high-voltage end in the motorcar air conditioner system.
(2) (see figure 2) when descent of piston, the rodless cavity volume-diminished gas of lower part of piston by compression, the first valve pressurized is closed, form the vibration damping air cushion and reduce automobile vibration intensity, simultaneously the part refrigerant gas backs down second valve along with second damping hole of piston is led in the increase of pressure, enters rod chamber, ready for piston stroking upward, go round and begin again.The working medium refrigeration agent is got back to rodless cavity more then in automotive air-conditioning system from the rodless cavity to the rod chamber, form closed folk prescription to flow circuits, the cooling action of condenser in the motorcar air conditioner system, make refrigeration agent form liquid state, enter the liquid container in the automotive air-conditioning system, replenish cooling power to automotive air-conditioning system, reach the purpose of energy-conservation minimizing kinetic equation loss.Because the buffer action of first one-way valve, second one-way valve can not influence motorcar air conditioner system operation working state.
Technological scheme of the present invention is: a kind of vibration damper that absorbs the vibrational energy refrigeration, comprise gas-storage cylinder, pipeline, piston rod guide, piston, it is characterized in that: be provided with two holes on the gas-storage cylinder, piston rod guide has a pipe hole, increase a pipeline in the gas storage district that gas-storage cylinder and clutch release slave cylinder form, piston only has second valve and one second damping hole of a direction.
Beneficial effect of the present invention: because the up-down vibration of automobile causes piston continuous motion up and down, go round and begin again, with the transformation of energy of up-down vibration is the automotive air-conditioning system cooling power, cooling power can satisfy the needs of air-conditioning requirement in the compartment, can reach the engine power of closing Driven Compressor, play the energy-conservation purpose of saving engine fuel, realized reducing under steam automobile vibration intensity simultaneously.
