What have the novel hydraulic shock absorber alleviates the collision hydraulic servo device
The utility model is described have a novel hydraulic shock absorber alleviate the collision hydraulic servo device, relate to a kind of new equipment that utilizes improved shock absorber and hydraulic efficiency gear to alleviate vehicle collision.
Increase, the speed of a motor vehicle along with vehicle improves at present, and the collision safety problem becomes increasingly conspicuous." at present the number that is killed in an automobile accident every year of the whole world reaches 1,000,000 people according to statistics, and wounded or disabled number reaches tens million of, and the number that domestic annual traffic accident causes death surpasses 80,000, and it is millions of to cause the wounded." key problem that solves auto against is efficient buffer absorbing structure and device, strives in collision case, accomplishing " car is ruined the people and do not died ", protects the driver and conductor effectively.
Present buffering energy-absorbing thinking is to make anterior (like the engine room part of the car) structure of car that suitable rigidity arranged; Can in collision, fully be out of shape and absorb energy; But this is difficulty relatively, also will support parts such as driving engine and car body because of it, and its rigidity can not be too little; Its structural materials is the steel member in addition, and energy-absorbing effect is also weaker.Often in many serious collision cases, significant amount of energy is delivered to operator's compartment, makes the operator's compartment gross distortion, although safety methods such as air bag, safety strap are arranged, can cause occupant's injures and deaths.
The operator's compartment of vehicle such as passenger vehicle and lorry does not have the crash protection of howdah car front structure at car foremost basically, and impact force acts directly on the operator's compartment; So in case crash; That will be more dangerous, and operator's compartment can be hit flat, and driver and conductor's life receives very big threat.Up to the present, also do not see the fender guard of taking any anticollision on the tack passenger and freight car, in the society this also has been accustomed to, but this is very irrational.3 hot issues of current auto trade, energy-conservation, in environmental protection and the safety, safety should make number one.The ideal standard of collision safety: " car is ruined the people and do not died " often become an empty verbiage in the tack passenger and freight car.From protecting driver and conductor's life security of this type car,, be very important for these tack passenger and freight car fit on actv. collision safety fender guards promptly from the angle of hommization.
To existing problem in the above-mentioned prior art, research and design a kind of later-model have a novel hydraulic shock absorber alleviate the collision hydraulic servo device, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the purpose of the utility model be research and design a kind of later-model have a novel hydraulic shock absorber alleviate the collision hydraulic servo device.Exist in the prior art in order to solve: tack passenger and freight car operator's compartment direct contact impingement area has no the problem of impact protection apparatus.
The technical solution of the utility model is achieved in that
The utility model is described have a novel hydraulic shock absorber alleviate the collision hydraulic servo device, form by bumper/spoiler, longeron and hydraulic damper; It is characterized in that having mesopore on the hydraulic damper piston rod on the described hydraulic damper, mesopore is connected with check valve on being contained in hydraulic damper; Check valve is connected with the actuator cylinder that is contained in the longeron front end through oil pipe; On the ram shaft of actuator cylinder roller is housed, roller freely is connected with bumper/spoiler.
When cruising, hydraulic damper is identical with original hydraulic damper effect.When bumping; After the pressure oil of actuator cylinder reaches certain pressure; Open the check valve on the shock absorber; The oil duct of high pressure oil in piston rod gets into the piston below, promotes piston and piston rod upward movement or cylinder body and moves downward, and promptly lifts car body through hydraulic damper to the lower pressure wheel tire or the top that makes progress.The extruding tire makes car retardation even braking downwards, reaches to alleviate loss and the harm that collision brings.
Hydraulic damper is the double as fluid servomotor after transforming, and it and regular fluid servomotor are different, and main difference is; Regular fluid servomotor piston has only a side that high pressure oil is arranged; And the piston upper and lower of hydraulic damper all has high pressure oil, owing to have flowing valve and two valves of rebound valve to link up two oil pockets up and down of piston on its piston, the oil pressure of two oil pockets is equated basically; But the area of piston below is greater than the area of piston top; So under the oil pressure effect, piston will be pushed up, only its running velocity is slower than the running velocity of regular fluid servomotor piston.
Hydraulic damper piston stroking upward just cylinder body is descending, and piston up causes vehicle frame and vehicle body to be lifted, and cylinder body descending causes pushing tire downwards.If the load of car or vehicle body are very heavy, the composition that pushes tire downwards is some more, otherwise; Vehicle frame becomes branch some more with vehicle body is lifted, but in any case, these all can consume a large amount of collision energies; If 4 hydraulic dampers of each car all acting words in collision; They possibly be very big to the buffering and the absorption of collision energy, if a large amount of collision energies is transferred on these shock absorbers, only surplus have few partial action on operator's compartment; May realize the target of " car is ruined the people and do not died ", promptly can solve the collision safety problem of tack passenger and freight car basically.The utility model is equally applicable on the miniature car that hydraulic damper is housed.
The utility model has the advantages that conspicuously, mainly show:
1, owing to used the utility model, played the effect that consumes the vehicle collision energy;
2, the utility model can be transformed processing on crude oil vehicle hydraulic shock absorber, greatly reduce cost.
The utlity model has novel structure, transform that processing is easy, cost-cutting, advantage such as safe and reliable, it puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.
