Description
Technical field
The utility model relates to the car suspension device, particularly a kind of effective energy-absorbing shock absorber for auto use.
Background technology
At present, the shock absorber of all kinds of cars all is to reduce compression speed and the bounce-back speed of coil spring (elasticity original paper) in cushion stroke with flowed friction, thereby reaches the vibration damping purpose.Because there is bigger compression rigidity in hydraulic structure, its rigidity effect has bigger damage rate to hydraulic packing and main car, and the technology difficulty of hydraulic packing is big, can only integral replacing when leakage of oil taking place suffering that rigidity is damaged, thus increased the productive costs and the maintenance hidden danger of main car.
The utility model content
It is a kind of for each sedans general-duty energy-obsorbing and damping device that the purpose of this utility model is to provide, and it can regulate and control assembly relation and load standard with each vehicle relatively under the condition that does not change physical construction and principle of work.
The purpose of this utility model is achieved through the following channels: a kind of car energy-obsorbing and damping device, and it comprises spring damper, the coil spring two ends of this spring damper are individually fixed in the upper end of piston rod and air cylinder, and are fixed by spring perch; The piston rod upper end connects with the body assembling seat, the assembly parts of air cylinder lower end connect with the vehicle bridge assembling stand, the piston rod main body is cylindric, its lower end is a piston, the guide holder that piston is installed through the air cylinder port is inserted in the air cylinder, the guide holder below of air cylinder inwall is equipped with sealing gland and sealing gland pad, seal ring is fixed on the end of piston by the fastening seat of piston, the axle center of piston is provided with the pressure limiting pore, the two ends of pressure limiting pore be communicated with respectively air cylinder on, following cylinder chamber, the bottom of air cylinder is provided with outgassing nonreturn valve, and the outgassing nonreturn valve valve body wall is provided with the circulation pore and connects barometric pressure.The piston rod outside is equipped with dust boot.
The utility model car energy-obsorbing and damping device adopts the most advanced and sophisticated energy-obsorbing and damping technology of mechanical air pressure and mechanical friction and replaces the conventional hydraulic device.Seal ring is that high-strength silicone rubber is made, it keeps friction drag and sealing effectiveness by the pressure controlling of the fastening seat of piston, make upper cylinder half chamber (more than the piston) and following cylinder chamber (piston is following) of air cylinder form the operation pressure condition, sealing gland adopts high resiliency silica gel to make, and it keeps the pressurized seal effect of outer ring face and inner ring face with the elastic deformation rate under the effect of assembling pressure.Outgassing nonreturn valve is washed open at the air pressure that piston is incremented during to lower compression, to strengthen the compression rigidity that free air capacity reduces piston.When piston was upwards upheld, outgassing nonreturn valve was sealed by predetermincd tension, promoted down the vacuum suction rate of cylinder chamber to reduce charge air.With the height air pressure of upper cylinder half chamber and the vacuum suction of following cylinder chamber piston is formed the extension resistance, thereby reduce helical spring bounce-back speed and rigidity.This product can be regulated and control vibration damping load according to air pressure flow and friction drag, reduce the vibration values of car with the dual energy-absorbing advantage of pressure technology and friction techniques, mechanical structured member does not have the physical factor of damage in job procedure, its damping efficiency promotes 40% than hydraulic product, useful life promotes 300% than hydraulic product, and cost and price on average reduces by 30% than hydraulic product.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an External view of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of car energy-obsorbing and damping device, it comprises spring damper, coil spring 2 two ends of this spring damper are individually fixed in the upper end of piston rod 3 and air cylinder 8, and are fixed by spring perch 1; Piston rod 3 upper ends connect with the body assembling seat, the assembly parts 9 of air cylinder 8 lower ends connect with the vehicle bridge assembling stand, piston rod 3 main bodys are cylindric, its lower end is a piston 6, the guide holder 4 that piston 6 is installed through air cylinder 8 ports is inserted in the air cylinder 8, guide holder 4 belows of air cylinder 8 inwalls are equipped with sealing gland 14 and sealing gland pad 5, seal ring 12 is fixed on the end of piston 6 by the fastening seat 7 of piston, the axle center of piston 6 is provided with pressure limiting pore 13, the two ends of pressure limiting pore 13 be communicated with respectively air cylinder 8 on, following cylinder chamber, the bottom of air cylinder 8 is provided with outgassing nonreturn valve 10, and outgassing nonreturn valve 10 valve body walls are provided with circulation pore 11 and connect barometric pressure.Piston rod 3 outsides are equipped with dust boot 15.
The principle of work of the utility model car energy-obsorbing and damping device is as follows: after this shock absorber assembled with car, coil spring 2 was compressed by the weight of vehicle body and shortens, and piston 6 to displacement down, is separated into upper and lower two-layer cylinder chamber with air cylinder 8 in air cylinder 8.When vibration is travelled in the vehicle bridge generation, piston rod 3 and coil spring 2 form compression continuously and uphold (bounce-back) under moment loading, cause piston 6 in air cylinder 8, to make reciprocating type up-and-down movement, when piston 6 during to lower compression, upper cylinder half chamber (more than the piston) forms vacuum because of volume strengthens, piston 6 is produced absorption resistance, following cylinder chamber (piston is following) forms air pressure because of volume diminishes, piston is produced resistance to compression pression, the gas of following cylinder chamber at first flows to the upper cylinder half chamber by pressure limiting pore 13 under action of pressure, gas is arranged simultaneously by the pore 11 outside pressure releases of circulating, air pressure when upper cylinder half chamber and following cylinder chamber reaches equivalent time, air pressure is washed outgassing nonreturn valve 10 open, reduces the compression rigidity of piston 6 to increase airshed.When piston 6 was compressed to stroke terminal, the gas of following cylinder chamber was in atmospheric pressure state, and the gas of upper cylinder half chamber is a little more than normal pressure.When piston 6 is upwards upheld, outgassing nonreturn valve 10 is sealed by predetermincd tension, following cylinder chamber forms vacuum because of volume strengthens, piston 6 is produced absorption resistance, the upper cylinder half chamber produces air pressure because of volume diminishes, piston 6 is produced the air pressure resistance, and the gas of upper cylinder half chamber flows by pressure limiting pore downward cylinder chambers 13 under action of pressure.Control the time length of upper cylinder half chamber air pressure with the gas flow rate of pressure limiting pore 13, the extension resistance that piston 6 is formed with vacuum and air pressure and reduce helical spring bounce-back speed and rigidity, when car produced little shaking at flat pavement running, the motion air pressure of piston 6 can not be washed the predetermincd tension of outgassing nonreturn valve 10 open.Only reach the purpose of energy-obsorbing and damping with the air-flow regulation and control of circulation pore 11 and pressure limiting pore 13.The friction drag that seal ring 12 produces at work has the double action that absorbs kinetic energy and compensation resistance.
