Abstract
The utility model discloses a vehicle collision safety cushioning device. A piston (3) arranged in a hydraulic oil cylinder composed of a cylinder body (2), and the front and the back cylinder head bodies (4) and (1) which are provided with the oil cavities and the oil-transportation channels is fixed with a piston rod (6) whose front end is connected with a rubber protective plate (9) whose interior is embedded with a metallic framework (901). The piston rod (6) is sheathed with a spring (5). One side of the hydraulic oil cylinder is provided with an oil pipeline (13) which is communicated with the oil-transportation channels on the front cylinder head body (4) and the back cylinder head body (1). An adjusting screw (16) is arranged on the back cylinder head body (1). The hydraulic oil cylinder is fixed on the framework of the vehicle chassis when the utility model is installed, and the rubber protective plate on the front of the hydraulic oil cylinder is arranged on the front part of the vehicle. When the vehicles are crashed, the speed of the rearward movement of the piston rod and the protective plate is reduced, and the damping and the buffer action on the generated collision impact are obviously increased. Thus, the fault rate and the personal casualty of the vehicles which are mutually crashed are greatly reduced, and the insurance performance and the safety and reliability performance are remarkably improved when the vehicles are crashed.
Description
Technical field
The utility model belongs to the damping buffering device of vehicle collision impulse force, is specially a kind of automotive crash safety insurance shock absorber.
Background technology
The phenomenon that collision mutually takes place automobile under steam takes place through regular meeting; automobile damage rate and personal casualty situation when colliding mutually in order to alleviate automobile; the general guar plate that the duroplasts of a horizontal positioned is installed in the front portion of car, the front portion at some cross-country cars (as Beijing jeep) that also has is fixed with the metal protection frame.But guar plate or the metal protection frame installed do not have damping and buffering effect to collision impact when vehicle collision, security insurance is poor.
Summary of the invention
The purpose of this utility model provides a kind of automotive crash safety insurance shock absorber, when this device collides mutually at automobile, can produce damping and buffering effect to its collision impact that causes, and the security insurance performance is good.
To achieve these goals, the utility model be by cylinder barrel and on have on the piston that is equipped with in the preceding cylinder head body in oil pocket and oil transportation duct and the hydraulic ram that back cylinder head body is formed, be fixed with piston rod, the front end of piston rod is connected with the preventing rubber plate that is inlaid with metallic framework in it, between preceding cylinder head body and preventing rubber plate, be equipped with spring on the piston rod, one side of hydraulic ram has the transport pipe that is connected with oil transportation duct on preceding cylinder head body and the back cylinder head body, is equipped with the set screw of scalable hydraulic fluid flow rate on the cylinder head body of back.
When using automotive crash safety of the present utility model to insure shock absorber, hydraulic ram is fixed on the skeleton of car chassis, and makes anterior rubber fender place the front portion of automobile.Also this device can be installed in the rear portion of automobile.When if automobile takes place to collide mutually with other automobile under steam; rubber fender and piston rod move backward; driving piston moves in hydraulic ram backward; hydraulic oil in the hydraulic ram just enters the front portion (set screw scalable hydraulic oil flow velocity and flow after the turn on the cylinder head body) of hydraulic ram via transport pipe by the oil transportation duct in the cylinder head body of back; hydraulic oil in the hydraulic ram has damping and buffering effect to piston mobile; add the use of the spring on the piston rod; the mobile backward speed of piston rod and preventing rubber plate that makes it slows down greatly; the damping and the buffering effect of the collision impact that produces during to collision obviously increase; making it the chance that two carbodies collide obviously reduces; again because the elastic reaction of preventing rubber plate; the damage rate and the personal casualty that make it to be collided vehicle significantly reduce, safety performance and safety and reliability when therefore improving its vehicle collision significantly.This apparatus structure is simply compact, and volume is little, and function is many, and stable working is reliable, and carrying moment is big, long service life.It also can be installed in normally used overhead traveling crane, tower crane, gauntry crane etc. needs the spacing position of safety.
