Abstract
An orthopedic joint device is provided, the device having an upper part, a lower part pivotably mounted thereon and an actuator fastened to the upper part and the lower part and having a drive shaft coupled to an output element via a force transmission device, the force transmission device having a load transmission element that can by adjusted depending on the load.
Claims19
An orthopedic joint device having an upper part, a lower part pivotably disposed thereon, and an actuator which is fastened to the upper part and the lower part and which comprises a driveshaft coupled to a driven element by way of a force transmission device, wherein the force transmission device comprises a load-dependently adjustable force transmission element, wherein the actuator comprises a hydraulic pump having a housing and the driven element comprises at least one displacement element, the at least one displacement element being coupled to the driveshaft and being mounted in the housing in a pump chamber, with the load-dependently adjustable force transmission element being disposed between the at least one displacement element and the driveshaft and bringing about a load-dependent change in a stroke of the at least one displacement element.
An orthopedic joint device comprising:
- an upper part;
- a lower part pivotably disposed on the upper part;
- and
- an actuator fastened to the upper part and the lower part, the actuator further comprising a hydraulic pump and a driveshaft, the driveshaft being coupled to a driven element by a force transmission device;
- wherein the force transmission device comprises a load-dependently adjustable and elastically-mounted force transmission element.
An orthopedic joint device comprising:
- an upper part;
- a lower part pivotably disposed on the upper part;
- and
- an actuator fastened to the upper part and the lower part, the actuator further comprising a hydraulic pump and a driveshaft, the driveshaft being coupled to a driven element by a continuously variable, adjustable transmission;
- wherein the continuously variable, adjustable transmission comprises a load-dependently adjustable and elastically-mounted conical pulley.
