Measurement device () for measuring the axial and/or radial load on a bearing () comprising an inner ring (), an outer ring () and a plurality of rolling elements () between the inner and outer ring. The measurement device () comprises a sensor ring () which may be positioned adjacent to and in close contact with the inner ring () or outer ring () of the bearing (), the sensor ring () having at least one weakening () at its circumference and at least one sensor () being positioned in the at least one weakening ().

Measurement device for measuring radial and/or axial forces

A clutch actuator unit comprises a housing (), a screw mechanism and an actuator head which at one end engages the screw mechanism () and at the other end has an actuating end (), which actuator head () can be displaced in axial direction by the screw mechanism upon driving the screw mechanism. The actuating end () of the actuator head () is displaceable in transverse direction with respect to the screw mechanism as well.

Clutch actuator unit

A continuously variable transmission system comprises a continuously variable transmission having two pulley sets each with two discs defining a V-shaped groove, drive means-for varying the width of said groove and a belt extending between said-pulley sets in the grooves thereof, as well as a forward-reverse control connected to the shaft of one of the pulley sets and a clutch connected to said forward-reverse control, said pulley sets, forward-reverse control and clutch each being provided with a respective actuator. The actuators of the forward-reverse control and of the clutch are of an electromechanical type.

Continuously variable transmission system

A pulley set for a continuously variable transmission unit, comprises a pair of discs accommodated on a shaft, and a screw mechanism which is concentric with respect to said discs and for moving the discs towards and from each other, said discs enclosing a V-shaped groove, for accommodating a belt, said screw mechanism being controllable by a control means. The control means including a motor unit, said motor unit comprising a stator and a rotor, one of said stator and rotor engaging the nut of the screw mechanism, and the other of said stator and rotor engaging the screw of the screw mechanism.
