    • A shock absorber assembly including a fluid for absorbing forces between the body and the wheel of a motor vehicle. The shock absorber includes a valve having a resilient disc engaging a piston for impeding the passage of fluid through the aperture of the piston. A bi-stable solenoid is disposed in the housing and is interconnected with the resilient disc of the valve. The bi-stable solenoid's armature is moveable between a first stable position for applying a first biasing force against the resilient disc of the valve and a second stable position for applying a second biasing force being less than the first biasing force against the resilient disc of the valve. The adjustment of the biasing force on the valve also adjusts the damping force of the shock absorber.

    • A relative velocity sensor in a vehicle suspension damper comprises an annular, radially polarized magnet at the top of the shock cylinder adjacent a sensor winding on the inside of the dust tube. A closed magnetic circuit is defined from the magnet through an annular magnetic member inside the magnet to the piston rod and back through the dust tube across the sensor winding to the magnet. Flux below the magnet is similarly confined through the cylinder and does not affect the sensor winding. The air gaps at the winding and the piston rod do not change with axial movement; and the flux linkage variation with axial movement is thus linear across the entire coil. A voltage is generated across the coil which is a strong and accurate signal of relative movement between the sprung and unsprung masses of the vehicle.

    • In shock absorber system 10, solenoid 18 varies the damping force by changing the position of spring seat 24, and the effective preload force, at the same time. In the normal, de-energized condition (with no current), damping forces are generated by the piston valve 30 including piston 20. The actuated valve spring 16 is relaxed and set in such a way that it applies only a minimum preload force to the rebound-side disc stack 28. The motion of the plunger 14, pin 32 and movable spring seat 24 assembly changes the spring force by varying the distance between the movable spring seat 24 and the stationary spring seat 22. In the energized state, applying current to coil 12 generates a pulling force on the plunger 14 in the direction of the core element 34 to attract plunger 14 towards the core 34 and across the initial gap 36 until it is in a direct contact with the core's surface 38. Maintaining plunger 14 at this position requires applying a continuous constant holding current to coil 12 so that the position of the plunger is preserved (and the high preload force at the same time). When current is no longer applied to the coil 12, then the pulling force is no longer generated, and the plunger assembly returns back to the original (soft) position due to the reverse action of the valve spring 16.
    • 在减震器系统10中,螺线管18通过改变弹簧座24的位置和有效的预载力同时改变阻尼力。 在正常的断电状态(没有电流)时,包括活塞20的活塞阀30产生阻尼力。致动的阀弹簧16被松弛和设定,使得其仅对最小的预紧力施加到 柱塞14,销32和可动弹簧座24组件的运动通过改变可动弹簧座24和固定弹簧座22之间的距离来改变弹簧力。在通电状态下,施加电流 线圈12沿着芯元件34的方向在柱塞14上产生拉力,以将柱塞14朝着芯34吸引并穿过初始间隙36,直到其与芯的表面38直接接触。将柱塞14保持在 该位置需要对线圈12施加连续恒定的保持电流,使得保持柱塞的位置(并且同时具有高的预紧力)。 当电流不再施加到线圈12时,则不再产生拉力,并且由于阀弹簧16的反作用,柱塞组件返回到原始(软)位置。
