CONTROLLED HYDRAULIC SHOCK ABSORBER

摘要

FIELD: automotive industry. ^ SUBSTANCE: controlled hydraulic shock absorber comprises telescopic hydraulic two-tube shock absorber. The rod of the shock absorber is made of a hollow rod provided with the flange having a groove for roller thrust bearing and vertical slots from the other side. The hollow of the rod receives the hollow rod of by-pass valve for permitting vertical movement. The top section of the rod is provided with trapezium right thread, and the bottom section is provided with the stop for the spring of the valve. The driven pinion is screwed on the threaded part of the rod of the by-pass valve. The bottom of the driven pinion abuts against the roller thrust bearing that is mounted in the groove in the flange of the hollow rod. The second driven pinion is screwed on the threaded part of the valve rod. The top side of the pinion abuts against the roller thrust bearing. The third roller thrust bearing is interposed between the driven pinions. The driven pinions engage the driving gears mounted on the shaft of the electric motor. The control unit is connected with the electric motor and receives the signal from the pickups of suspension vibration and velocity pickup. ^ EFFECT: improved shock absorbing.
