Abstract
The utility model relates to an energy absorber for car collision, which is mainly composed of a sliding sleeve, a guiding sleeve, a spindle, shearing components and a positioning sleeve. The shearing components comprise shearing bumps, shearing concave rings and sheared plates. 60-400 groups of shearing components are orderly pressed and arranged in the positioning sleeve and sheathed on the spindle. Gaps whose thickness is 1-1.5 times as thick as the thickness of the sheared plates are reserved between the sheared plates and the shearing bumps in the adjacent shearing components. The utility model is mainly used for a car to prevent the occurrence of malignant collision accidents. When the car is collided, collision force is transferred to the shearing bumps by the sliding sleeve arranged on the back face of the bumper to make the sheared plates orderly sheared, and thus giant energy of collision is gradually absorbed and consumed to reduce the collision force of a car body.
Description
Endergonic a kind of device when the utility model relates to auto against belongs to automotive safety protection spare and accessory parts technical field.
Along with rapid economy development, various vehicles are increasing, and inevitably automobile collision accident becomes puzzlement people's a difficult problem.The at present domestic Federal bumper that generally uses is a kind of rigid support basically, is contained in the automobile forward position, can only be when slight impact to collision thing resistance shelves once.When bigger collision takes place, can't absorb collision energy at all and the vehicle and the person are played a protective role.
The purpose of this utility model is to overcome weak point of the prior art, and provide a kind of and when bigger collision takes place automobile, the huge energy of collision progressively can be absorbed consumption, and the auto against energy absorber of avoiding serious accident to take place.
The technical solution of the utility model is: the auto against energy absorber comprises sliding sleeve, axle, shearing projection, is sheared plate, shears recessed circle, forward and backward orienting sleeve and locating bush primary member.In the orienting sleeve, both became free-running fit before described sliding sleeve was arranged on.Described shearing projection, be sheared plate, shear each one on recessed circle and constitute one group of shearing component, 60--400 group shearing component is fitted in the locating bush successively, shear projection, be sheared between plate and the axle gapped.The recessed circle of shearing that is sheared in plate and next group between adjacent component in last one group compresses, and the gland at available two ends compresses; Being sheared between the shearing projection in plate and next group in last one group leaves 1-1.5 doubly to the gap that is sheared plate thickness, so that each shearing component is cut successively.The locating bush in the shearing component outside can guarantee suitable shear gap, and plays protective action.The back segment of axle becomes free-running fit with the back orienting sleeve.
In the above scheme, described axle is a hollow shaft, with expendable weight.Sliding sleeve can become free-running fit with axle, also can be linked to be integral body, to be fit to the structure needs of long and short resorber.Shear projection and be sheared plate and be provided with through hole, for exhaust and expendable weight.Axle is provided with air discharge duct, and the orienting sleeve endoporus is provided with oil resevoir, to guarantee that resorber work flexibly, reliably.
When the utility model used, sliding sleeve linked to each other with Federal bumper, and forward and backward orienting sleeve links to each other with vehicle body.When bigger collision took place automobile, the sliding sleeve pressurized was passed to the shearing projection with impact, and the plate that is sheared of each assembly is cut successively, so progressively absorb the huge energy when consuming collision.The impact that acts on like this on the vehicle body will can be very not big, thereby avoid serious accident to take place.The impaired replaceable repairing in back of shearing component.The utility model can be used for other transport facilitys such as train, power driven vessel after improving.
Further specify the utility model embodiment below in conjunction with accompanying drawing.
Accompanying drawing is the utility model structural representation.
As figure, the inside and outside circle of sliding sleeve 1 respectively with 3 one-tenth free-running fits of hollow shaft 2 and preceding orienting sleeve.By shear projection 6, shear recessed circle 7 and be sheared shearing component that plate 8 constitutes totally 150 groups be fitted in successively in the locating bush 9, shearing projection and hollow shaft gap is 0.04 millimeter, being sheared plate and hollow shaft gap is 0.5 millimeter.The recessed circle of shearing that is sheared in plate and next group between adjacent component in last one group compresses with gland 5; Being sheared between shearing projection in plate and next group in last one group has 0.9 millimeter gap.Be sheared plate and made by the T10 steel plate, shearing diameter is 100 millimeters of φ, and thickness is 0.8 millimeter.12 one-tenth free-running fits of the back segment of axle and back orienting sleeve.Shear projection and be sheared plate and be provided with through hole 10.Air discharge duct 11 is arranged on the hollow shaft.Orienting sleeve and sliding sleeve endoporus have oil resevoir 4.
Claims (7)
1, a kind of auto against energy absorber, it is characterized in that, this resorber comprises sliding sleeve, axle, shear projection, be sheared plate, shear recessed circle, before, back orienting sleeve and locating bush primary member, described sliding sleeve is arranged in the preceding orienting sleeve, both become free-running fit, described shearing projection, be sheared plate, shear each one on recessed circle and constitute one group of shearing component, 60-400 group shearing component is fitted in the locating bush successively, shear projection, be sheared plate and axle is gapped, the recessed circle of shearing that is sheared in plate and next group between adjacent component in last one group compresses, and and leave 1-1.5 doubly to the gap that is sheared plate thickness between the shearing projection in next group, the back segment of axle becomes free-running fit with the back orienting sleeve.
