Question

which clutch disc component contains the splines that allow the clutch to ride on the input shaft?
○ a. the wavy springs
○ b. the friction facing
○ c. the damper
○ d. the hub

Explanation:

To determine the clutch disc component with splines for riding on the input shaft, we analyze each option:

• Option a: Wavy springs are for dampening vibrations, not for splines on the input shaft.
• Option b: Friction facing provides friction for engagement, no splines here.
• Option c: The damper reduces torsional vibrations, not related to input shaft splines.
• Option d: The hub of the clutch disc has internal splines that mate with the external splines of the input shaft, allowing the clutch to ride (slide) on the input shaft.

Answer:

d. The hub
