Abstract
The invention relates to a clutch module for prostheses, in particular for prosthetic grippers, arm prostheses or hand prostheses that comprise a chassis to which at least one finger prosthesis is articulated, the clutch module including a drive element, a driven element and a clutch device, which shifts between two gear stages depending on the torques applied to the driven element.
Claims18
A clutch module for a prosthesis including a chassis to which at least one finger prosthesis is articulated, the clutch module comprising:
- a drive element;
- a driven element;
- a clutch device;
- first and second clamping bodies, which couple the drive element to the driven element in a torque-controlled manner;
- wherein the clutch device shifts between two gear stages depending on the torques applied to the driven element;
- wherein the clutch device shifts between the gear stages with different increases in speed and independently of the direction of rotation of the drive element;
- wherein the clutch device contacts the first and second clamping bodies.
A clutch module for a prosthesis including a chassis to which at least one finger prosthesis is articulated, the clutch module comprising:
- a drive element;
- a driven element;
- a clutch device;
- wherein the clutch device shifts between two gear stages depending on the torques applied to the driven element;
- wherein the clutch device shifts between the gear stages with different increases in speed and independently of the direction of rotation of the drive element;
- wherein the clutch device includes two switching elements, which are mounted to be pre-stressed and to turn in relation to each other, wherein the switching elements have switching webs or switching pins, which can be bought into contact with the clamping bodies in a torque-controlled manner.
A clutch module for a prosthesis including a chassis to which at least one finger prosthesis is articulated, the clutch module comprising:
- a drive element;
- a driven element;
- a clutch device;
- wherein the clutch device shifts between two gear stages depending on the torques applied to the driven element;
- wherein the clutch device shifts between the gear stages with different increases in speed and independently of the direction of rotation of the drive element;
- wherein the clutch device contacts first and second clamping bodies, which couple the drive element to the driven element in a torque-controlled manner;
- wherein the drive element is coupled to a gear mechanism which has a contact ring, which contacts the first clamping bodies to transmit high torque.
