A clutch actuator for a manual-shift motor vehicle transmission, includes a driver-operated clutch pedal or lever, a clutch linkage between a clutch of the motor vehicle and the pedal or lever, and a damper adapted to delay clutch engagement on a fast release of the clutch pedal or lever. The damper is effective to delay clutch engagement only within a limited range of a whole clutch engagement movement and is substantially ineffective outside the limited range and within the whole range of a clutch disengagement movement.

A magnetic spring assembly that uses the bistable magnetic nature of permanent magnets mediated by a spring material to allow one or more attached vibrating masses to take on the damping characteristics of the magnetic spring assembly includes a permanent magnet body with an attach point 15 for a first vibrating mass, two spring materials, and two magnetic disks firmly attached to a shaft having an attach point 23 for a second vibrating mass to manufacture a mass damper 20 for damping vibrations on at least one of the attached masses. The spring materials can be an elastic material or a spring that is placed between the magnetic disks and the magnetic body to allow the magnetic disks to vibrate in a spring like manner. Passive tuning of the damping characteristics of the magnetic spring assembly is achievable through selected force tuning between the magnetic force from the permanent magnet and the compression force of the spring materials, and active tuning of the magnetic spring assembly is achievable by adding control coils in the magnet body to alter the magnetic force or having spring materials with characteristics that are electrically control to alter the compression force.
