Driveline for a vehicle
A driveline 1 comprises a transmission 7 having an input shaft 9 and an output shaft 13 as well as an end drive 19 connected to the output shaft of the transmission, which end drive includes a differential 21. The transmission comprises a plurality of switchable gear trains as well as a shift drum 23 which has three cam profiles 25, 27, 29 and three shift forks S01, S23, S4X provided with cam followers for moving a clutch element for coupling a gear to a shaft present in the transmission. The shift drum 23 further includes a further cam profile 31 and the transmission comprises a further cam follower F4 as well as a locking element which is connected via a gear unit 35 to the further cam follower and locks a driving element 37 in the driveline so that drive shafts connected to the differential are locked against rotation.
Interlock mechanism
An interlock mechanism includes a shift-and-select shaft a first fork, a second fork, a first inner lever, a second inner lever, an interlock member coaxially arranged around an outer circumference of the shift-and-select shaft while being allowed to rotate together with the shift-and-select shaft in the rotation direction as a unit and not allowed to be displaced in the axial direction, a first engagement portion formed on the first fork, a second engagement portion formed to project from the second fork, a first engaged portion formed to project from the inter lock member and engaged with the first engagement portion while the interlock member is positioned at a second rotation position and a second engaged portion formed on the interlock member and engaged with the second engagement portion while the interlock member is positioned at a first rotation position.
DRIVING DEVICE WITH A PARKING LOCK ARRANGEMENT AND DRIVABLE VEHICLE AXLE WITH A DRIVING DEVICE
A drive unit with a parking lock arrangement has a parking lock gear, a parking lock pawl, and a parking lock tappet. An actuation unit can move the tappet against a shifting force into a locking shift position in which the tappet enables an actuating movement of the pawl toward a release position, in which the pawl enables a rotary movement of the parking lock gear. The actuation unit is operatively connected to a shift actuator system of a manual gearbox having at least two speeds. The actuation unit is configured to transfer the tappet from the locking shift position to the releasing shift position by means of spaced-apart cams when one of the speeds is engaged. In a neutral operating state, where no speed is engaged and the power train is interrupted, the actuation unit releases the actuating movement of the tappet toward the locking shift position.
INTEGRATED DISCONNECT AND PARK LOCK ACTUATION SYSTEM
An actuation system of actuating both a disconnect device and a park lock is provided. The system includes a motor actuator that drives an oil pump, with the same output of the motor actuator controlling the disconnect device and the park lock. The system includes a translator mechanism, which converts rotary movement of a selectable output shaft into linear movement of a lock collar. Rotation in the first direction sequentially engages the disconnect device and then the park lock, while maintaining the disconnect device in the connected state. Rotation in the second direction first disengages the park lock and then the disconnect device. The selectable output mechanism may be a selectable clutch that, when connected, transfers forward or backward rotary movement of the motor actuator output to shift the translator forward or backward.
Bottom-bracket gear
An arrangement for actuating a shift element for a bottom bracket gearbox (1) includes a shift ring (4) rotatably mounted in a housing (3) and assigned to a gearbox component. A shift pawl (5) for locking or releasing the shift ring (4) is assigned to the shift ring (4) for shifting a gear stage. A support region mechanically reinforces the housing (3) and is provided at least along a contact region (14) between an inner wall (8) of the housing (3) and an outer circumference of the shift ring (4). The contact region (14) is defined by reaction forces (16) acting when the shift ring (4) is locked.
MOTOR VEHICLE WITH AN ENGAGEMENT DEVICE OF A GEARBOX AND A PARKING BRAKE DRIVEN BY A SAME ACTUATOR
A transmission is disclosed that comprises a gearbox comprising at least one input shaft, one output shaft, and at least one engagement device operable to engage a relative gear ratio between the input shaft and the output shaft, a drive assembly comprising a rod coupled to the engagement device and an actuator device configured to translate the rod along an axis between a first position, where the rod leads the engagement device to engage the gear ratio, and a second position, a parking brake comprising a first member and a second member movable between a locking position, in which the second member engages the first member to lock the transmission, and a release position, in which the first and second members are spaced apart, the drive assembly comprising a locking mechanism that leads the second member into the locking position in response to the rod translating into the second position.
TRANSMISSION AND METHOD FOR SHIFTING GEARS
A transmission includes an input shaft, an input gear, a shaft, a drive gear, a dog gear, an output gear, and a shifting assembly. The input gear is connected to the input shaft. The drive gear, the dog gear and the output gear are connected to the shaft. The drive gear drivingly engages the input gear. The dog gear selectively axially translates along the shaft between an engaged dog position in which the dog gear is drivingly engaged with the drive gear, and a disengaged dog position in which the dog gear is disengaged from the drive gear. The shifting assembly, which has drive and neutral configurations, includes a shift drum, a retainer, a retainer biasing member, a shift fork and a shift fork biasing member. In the drive configuration, the retainer is in an extended position, and prevents the shift fork from moving toward a disengaged fork position.
