Abstract
A dog clutch assembly for a transmission assembly of a work vehicle includes a first toothed wheel, a selector carried by one of an input shaft or an output shaft, and a second toothed wheel configured to selectively engaged with the first toothed wheel, and an actuator configured to move the selector along a reference axis between a first neutral position, in which the first toothed wheel and the second toothed wheel are disengaged, and a second engaged position, in which the first toothed wheel and the second toothed wheel are engaged. The actuator including a fork configured to be operatively interposed between the selector and the actuator.
Claims16
A dog clutch assembly for a transmission assembly of a work vehicle, the dog clutch assembly comprising:
- a first toothed wheel carried in a rigid manner by a second transmission member;
- a selector carried in an axially slidable and angularly rigid manner by one of an input shaft or an output shaft, and provided with a second toothed wheel configured to selectively engaged with the first toothed wheel;
- and
- an actuator configured to move the selector along a reference axis between a first neutral position, in which the first toothed wheel and the second toothed wheel are disengaged, and a second engaged position, in which the first toothed wheel and the second toothed wheel are engaged, wherein,
- the actuator includes a fork configured to be operatively interposed between the selector and the actuator, in order to be able to transmit a force exerted by the actuator to the selector to move the selector between the first neutral position and the second engaged position,
- the dog clutch assembly further comprising a support element interposed between the fork and the selector, wherein the support element is carried in a free rotatable manner and axially rigid manner by the selector and is connected to the fork, so as to move integral with the fork, and
- the dog clutch assembly is configured to transmit torque between the input shaft and the output shaft extending along the reference axis by a transmission operatively interposed between the input shaft and the output shaft and comprising a first transmission member carried by a first one between the input shaft and the output shaft and the second transmission member carried by a second one between the input shaft and the output shaft and operatively connected to the first transmission member.
(canceled)
A work vehicle comprising:
- a transmission assembly including a dog clutch assembly, wherein the dog clutch assembly includes:
- a first toothed wheel carried in a rigid manner by a second transmission member;
- a selector carried in an axially slidable and angularly rigid manner by one of an input shaft and an output shaft and is provided with a second toothed wheel configured to selectively engaged with the first toothed wheel;
- and
- an actuator configured to move the selector along a reference axis between a first neutral position, in which the first toothed wheel and the second toothed wheel are disengaged, and a second engaged position, in which the first toothed wheel and the second toothed wheel are engaged, wherein,
- the actuator includes a fork configured to be operatively interposed between the selector and the actuator, in order to be able to transmit a force exerted by the actuator to the selector to move the selector between the first neutral position and the second engaged position,
- the dog clutch assembly further comprising a support element interposed between the fork and the selector, wherein the support element is carried in a free rotatable manner and axially rigid manner by the selector and is connected to the fork, so as to move integral with the fork, and
- the dog clutch assembly is configured to transmit torque between the input shaft and the output shaft extending along the reference axis by a transmission operatively interposed between the input shaft and the output shaft and comprising a first transmission member carried by a first one between the input shaft and the output shaft and the second transmission member carried by a second one between the input shaft and the output shaft and operatively connected to the first transmission member.
