Abstract
The utility model relates to a hydraulic bumper for automotive vehicle. A connecting device and a hydraulic damping apparatus are respectively connected between the chassis and the bumper of the motor vehicles. The connecting device comprises a front and a back hinge. The hydraulic damping apparatus are respectively mounted between the bumper and the chassis of the motor vehicle. The problem that the bumper for automotive vehicle is short of the safety function for a long time can be solved to protect the security of the life and the property of people. The utility model has the advantages of simple and reliable structure, and the utility model is an ideal component of the motor vehicle.
Description
The utility model relates to a kind of hydraulic pressure of motor vehicle damping bumper.
In a single day self-propelled vehicle clashes under steam, the bump vibrations will seriously jeopardize the safety of people's lives and properties.
The purpose of this utility model just is to alleviate above-mentioned harm, and a kind of hydraulic pressure of motor vehicle damping bumper that can alleviate the bump vibrations is provided.
For achieving the above object, between motor-vehicle chassis and bumper/spoiler, hydraulic damping device is installed, is made bumper/spoiler have very strong security insurance function, solved the problem of bumper for automotive vehicle shortage insurance function for a long time.
Hydraulic pressure of motor vehicle damping bumper of the present utility model is to be made of bumper/spoiler, connecting device and hydraulic damping device etc., and it is with connecting device hydraulic damping device to be installed between bumper/spoiler and the chassis, utilizes hydraulic damping device to alleviate the bump vibrations.
Described bumper/spoiler has two kinds, and a kind of is common simple insurance thick stick, is applicable to normal control vehicle; Another kind is the square frame bumper/spoiler, is applicable to cab-over-engine vehicle.
Described connecting device is to be used for hydraulic damping device is installed between bumper/spoiler and the chassis.The simple insurance thick stick connects with hinge; The square frame bumper/spoiler connects with live ball or connects with universal-joint.
Described hydraulic damping device is made up of oil cylinder, flow regulating valve, check valve and fuel supplement device etc.It is the shock damping action that utilizes flow regulating valve, and making self-propelled vehicle is not to stop suddenly when bump takes place, but slows down gradually, thereby has alleviated the intensity and the destructive force of bump vibrations.
When bump takes place, move after bumper/spoiler is forced to, and promote to move behind piston rod and the piston by preceding hinge or universal-joint, oil cylinder back cavity fluid pressurized, pressure oil flows to ante-chamber by throttle gate.Because the shock damping action of throttle gate slows down vehicle gradually, thereby play the shock-absorbing protecting effect.For avoiding excessive bump to cause piston slap oil cylinder rear portion, the oil cylinder rear portion can be designed to the buffer-type structure.
After bumper/spoiler fwd pressure was removed, available hand was pulled out bumper/spoiler forward.At this moment, the fluid pressurized of oil cylinder ante-chamber, pressure oil flows to back cavity by check valve.Because of the one-way function of check valve, make the bumper/spoiler behind the bump can be easy to reset.If the piston with having one-way function can save check valve, but, then must use check valve if use ram cylinder.
When using the simple insurance thick stick, two oil cylinders are loaded on respectively in the square groove of channel-section steel front portion, chassis; When using the square frame bumper/spoiler, four oil cylinders are loaded on four jiaos of bumper/spoiler respectively, in the inside angle steel inboard of four openings of front portion, chassis, angle steel is fixed in the front portion, chassis with support.
The effect of fuel supplement device, the one, the variation of oil cylinder volume when moving forward and backward for adapting to piston, the 2nd, have the effect of refueling and exitting.
Hydraulic pressure of motor vehicle damping bumper of the present utility model can alleviate the bump vibrations, and the safety of protection people lives and properties has tangible economic results in society, and has simple in structure, reliable characteristics.
Below in conjunction with a description of drawings embodiment of the present utility model.
