Cone clutch

from Wikipedia, the free encyclopedia
Visualization of a cone coupling:
1: cone elements
2: splined shaft
3: friction lining
4: return spring
5: control
6: coupling can be used in both directions

A cone clutch is a frictionally engaged , switchable clutch , the effect of which is produced by two cone elements equipped with friction surfaces .

functionality

Cone coupling with housing partially open for illustrative purposes

The cone coupling has two cone elements with the same cone angle. One of the two conical elements can be displaced in the axial direction, for example by being used on a splined shaft. When the clutch is actuated, a contact pressure is applied in the axial direction, which creates normal forces on the lateral surfaces of the conical elements. This normal force is proportional to the contact pressure and also dependent on the cone angle: the flatter the cone, the higher the normal force generated. In practice, cone angles close to 0 ° cannot be achieved, since full engagement of the clutch would not be possible in this case. In automotive engineering , cone angles of 6.5 ° are common.

The torque that can be transmitted by the cone clutch is proportional to the normal force on the conical surfaces and also depends on the coefficient of friction of the friction surface. The higher the coefficient of friction, the higher the transmittable torque. Possible materials for friction surfaces are steel , brass or molybdenum .
