The utility model is achieved through the following technical solutions:
Strengthen an automobile absorber for stability, comprise Packed housing, the piston in housing and connect and pass the piston rod of housing with piston, the underpart in housing is provided with Fuel Tanking Unit; The same circumference of take on piston is evenly provided with the intercommunicating pore of vertical perforation piston as the center of circle, the shaft section of described intercommunicating pore is isosceles trapezoid, adjacent two intercommunicating pores are centrosymmetric, on each intercommunicating pore, be provided with one-way valve, the opposite direction of one-way valve on adjacent two intercommunicating pores, one-way valve is all installed on the end that intercommunicating pore area is little; On Fuel Tanking Unit, be also evenly provided with through hole, on each through hole, be provided with one-way valve, the opposite direction of the one-way valve on adjacent two through holes.
Between piston in housing and housing upper end portion, be provided with guide structure, guide structure is circular cone, and circular cone is fixed with inner walls, and circular cone circle centre position has the endoporus through piston rod, is provided with the discharge orifice of vertical perforation circular cone on circular cone.
The end face that in circular cone, area is little is relative with piston.
The area of discharge orifice is greater than half of area of the end face that in the circular cone of guide structure, area is large.
The height of circular cone is no more than 1/3 of depth pistion.
In Fuel Tanking Unit, be provided with oil storage sponge.
The utility model beneficial effect is compared with the existing technology, by the epicoele of the technical program and the volume ratio of cavity of resorption, increase, and the damping force of first vibrations decreases, make damping reaction not obvious, can effectively reduce the wearing and tearing to seal arrangement and piston simultaneously.
