Abstract
A manual shift transmission is disclosed which includes a shaft, at least one loose wheel carried by the shaft and a gear shift sleeve, which is moveable along the first shaft between a gear position coupling the first loose wheel to the shaft and a neutral position allowing a rotation of the loose wheel against the shaft. A gear shift follower is configured to move the gear shift sleeve along the shaft and acts on the gear shift sleeve. An actuating rod can be shifted in the direction of the shaft for shifting the gear shift follower. The actuating rod carries a clutch body which is adjustable between an active position engaging in a recess of the gear shift follower and a passive position sunk into the first actuating rod.
Claims15
A manual shift transmission comprising:
- a first shaft;
- at least one first loose wheel carried by the first shaft;
- a first gear shift sleeve, which is moveable along the first shaft between a first gear position coupling the first loose wheel to the first shaft and a first neutral position allowing a rotation of the first loose wheel relative to the first shaft;
- a first gear shift follower acting on the first gear shift sleeve for moving the first gear shift sleeve along the first shaft;
- a first actuating rod for shifting the first gear shift follower in a direction towards the first shaft, wherein the first actuating rod comprises a first actuating sleeve and a first control rod moveable in the first actuating sleeve, and wherein the first actuating sleeve comprises a passage, and the first control rod comprises an exterior surface and at least one recess extending through the exterior surface into the first control rod;
- a first clutch body carried on the first actuating rod and comprising at least a first ball, the first clutch body being adjustable between
- a first active position in which the first ball is received within the passage of the first actuating sleeve and in a first recess of the first gear shift follower, and
- a first passive position in which the first ball is received within the passage of the first actuating sleeve and the at least one recess of the first control rod, and
- wherein, in the first active position, the at least one recess of the first control rod is offset relative to the passage of the first actuating sleeve such that the first ball is transferred out of the at least one recess of the first control rod and at least partially out of the passage of the first actuating sleeve by the exterior surface of the first control rod into the first recess of the first gear shift follower;
- and
- a slotted link defining a groove with axially offset first and second circumferential sections joined by a helical section;
- and a cam arranged within the groove and coupled to the first actuating sleeve such that rotation of the slotted link forces the cam to axially shift the first actuating sleeve.
