The back-flow velocity of the hydraulic oil in the prior art car vibration damper damper hydraulic damping chamber is fixed, and both no matter damping spring is subjected to great pressure, what has been compressed, and the reset speed of damping spring is all fixed.Need to prove that the back-flow velocity of described hydraulic oil is not meant the speed that hydraulic oil flows, and is meant that hydraulic oil flows back to the speed of oil cylinder from the hydraulic damping chamber.And the jarring forces that car ran in the actual travel process is Protean, and the compressed degree of damping spring also has nothing in common with each other.In the compressed degree of damping spring hour, should allow damping spring reset to recover the situation of smooth-ride as early as possible with fast speeds; When the compressed degree of damping spring is big, should allow damping spring reset to avoid causing the secondary vibrations with slower speed.Obviously, prior art car vibration damper damper can not satisfy above-mentioned requirements, and the damping force of vibration damper damper can not be regulated automatically with the jarring forces that car is subjected to, and its damping effect is limited, directly has influence on travelling comfort and Security that car is driven.
Summary of the invention
Can not regulate automatically with the jarring forces that car is subjected to for solving the damping force that prior art car vibration damper damper exists, problem such as damping effect is limited the utility model proposes a kind of car vibration damper damper.The utility model car vibration damper damper is not provided with throttle orifice on the piston of piston assembly, and at the inner core inwall throttling groove that cross-section area diminishes gradually is set axially.
Further, to be arranged on the throttling groove that the axial cross-section area of inner core inwall diminishes gradually be one or one or more to the utility model car vibration damper damper.
Further, the utility model car vibration damper damper shape of cross section of being arranged on the throttling groove that the axial cross-section area of inner core inwall diminishes gradually is semicircle, triangle or trapezoidal.
The useful technique effect of the utility model car vibration damper damper is that the damping force of vibration damper damper can be regulated automatically along with the compressed degree of damping spring, and compression degree is big more, and damping force is also just big more; Otherwise, then more little, and be continuous variation.The utility model car vibration damper damper has effectively improved the damping of car vibration damper, has improved travelling comfort and Security that car travels.
