Abstract

Official abstract text for this publication.

This clutch control device includes a clutch apparatus configured to connect and disconnect power transmission between a prime mover and an output target, a clutch actuator configured to output a driving force for actuating the clutch apparatus, and a driving mechanism configured to receive the driving force of the clutch actuator and actuate the clutch apparatus, and the driving mechanism is able to apply a driving force in either a disconnecting direction or a connecting direction to the clutch apparatus.

First claim

Opening claim text (preview).

What is claim is: 1. A clutch control device comprising: a clutch apparatus configured to connect and disconnect power transmission between a prime mover and an output target; a clutch actuator configured to output a driving force for actuating the clutch apparatus; and a driving mechanism configured to receive the driving force of the clutch actuator and actuate the clutch apparatus, wherein the driving mechanism is able to apply the driving force in either a disconnecting direction or a connecting direction to the clutch apparatus, the clutch actuator applies the driving force in a clutch connecting direction to the clutch apparatus according to an operation situation of the prime mover, the clutch apparatus comprises a spring member configured to generate a pressing force in the clutch connecting direction, the clutch actuator applies the driving force in the clutch connecting direction to the clutch apparatus by a driving source separate from the spring member, in addition to a biasing force of the spring member, only in a previously determined operation situation of the prime mover, the driving mechanism comprises a first transmission member on a side of the clutch actuator and a second transmission member on a side of the clutch apparatus, and the first transmission member is in constant mechanical engagement with the second transmission member. 2. The clutch control device according to claim 1 , wherein the clutch control device is applied to a vehicle, and the clutch actuator applies the driving force in the clutch connecting direction to the clutch apparatus during acceleration of the vehicle. 3. The clutch control device according to claim 1 , wherein the driving mechanism constitutes a rack and pinion configured to convert rotational movement of the first transmission member into reciprocal movement of the second transmission member, and a pinion gear included in the driving mechanism is formed in a fan shape when seen in an axial direction. 4. The clutch control device according to claim 1 , wherein the clutch actuator comprises the driving source configured to output the driving force and a transmission mechanism configured to link the driving source and the clutch apparatus, the driving source and the first transmission member that is an output member of the transmission mechanism are arranged in parallel in a first direction with their axial directions parallel to each other, and the second transmission member that is an input member of the clutch apparatus is disposed between the driving source and the first transmission member in the first direction.
