Clutch module for prosthesis
View Patent ↗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.
1. 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.
2. The clutch module of claim 1 , wherein the driven element is configured to be driven for a low torque with a high increase in speed and for a high torque with a low increase in speed.
3. The clutch module of claim 1 , 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 brought into contact with the clamping bodies in a torque-controlled manner.
4. The clutch module of claim 3 , wherein the switching elements are kept pre-stressed by springs.
5. The clutch module of claim 1 , 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.
6. The clutch module of claim 1 , wherein the first and second clamping bodies are arranged on a common driver disk.
7. The clutch module of claim 6 , wherein the driver disk includes a frame on which the first clamping bodies are arranged to provide a low increase in speed.
8. The clutch module of claim 6 , wherein the driver disk includes a frame, in which the second clamping bodies are arranged for a high increase in speed.
9. The clutch module of claim 6 , wherein gearwheels, which engage and turn a switching ring in relation to a switching disk and a switching element, are mounted on the driver disk.
10. 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.
11. The clutch module of claim 10 , wherein the clutch device contacts first and second clamping bodies, which couple the drive element to the driven element in a torque-controlled manner.
12. The clutch module of claim 10 , wherein the driven element is configured to be driven for a low torque with a high increase in speed and for a high torque with a low increase in speed.
13. The clutch module of claim 10 , wherein the switching elements are kept pre-stressed by springs.
14. 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.
15. The clutch module of claim 14 , wherein the first and second clamping bodies are arranged on a common driver disk.
16. The clutch module of claim 15 , wherein the driver disk includes a frame on which the first clamping bodies are arranged to provide a low increase in speed.
17. The clutch module of claim 15 , wherein the driver disk includes a frame, in which the second clamping bodies are arranged for a high increase in speed.
18. The clutch module of claim 15 , wherein gearwheels, which engage and turn a switching ring in relation to a switching disk and a switching element, are mounted on the driver disk.
