Title: Electro-hydraulic brake actuator - with automatic stroke adjustment to compensate for brake wear with manual override adjustment
Inventor: HENRICH KURT
IPC: F16D65/56
Filed: 1973-11-29
Abstract: The actuator has a hydraulic piston whose piston rod is rotatable relative to the piston and has a screw-threaded connection with an output element. The rod also embodies a first helical gear meshing with a second helical gear mounted through a freewheel on a spindle such that axial movement of the rod in the return direction causes the rod to rotate by an amount determined by the backlash between the gears, thereby automatically adjusting the position of the non-rotatable output element for wear. To adjust the backlash the spindle is supported for manual rotation on eccentric pins, one of which is secured to a releasable locking device.
