A shifting device (1) for the powertrain of a motor vehicle, including a control shaft (10) for adjusting a control element (9), the control shaft (10) has a first sub-section (15) which can be driven by an actuator (36) and a second sub-section (16) which is designed to adjust the control element (9). The first sub-section (15) is rotatably mounted relative to the second sub-section (16). A spring element (11), via which a torque of the first sub-section (15) can be transmitted to the second sub-section (16), is provided between the two sub-sections (15, 16).

A trailer for towing a power vehicle with a towable frame forming an undercarriage chassis and a tandem wheel assembly positioned under the undercarriage chassis. The tandem wheel assembly having a first wheel assembly, a second wheel assembly and an extension assembly moving the second wheel assembly along a longitudinal axis of the chassis between trailing position and self-propelled position, with the first wheel assembly and the second wheel assembly are positioned to support the undercarriage chassis.

An electric drive unit clutch for an automobile includes a first rotatable shaft, a one-way clutch fixedly mounted onto the first rotatable shaft, a dog clutch slidingly mounted onto the first rotatable shaft and adapted to rotate with the first rotatable shaft, a clutch ring positioned between the one-way clutch and the dog clutch, and a second rotatable shaft rotatable engaged with the clutch ring, wherein the clutch ring is adapted to transfer rotational motion from the second rotatable shaft through the one-way clutch and the dog clutch to the first rotatable shaft.

A transmission assembly for an electric drive comprises a drive shaft, a reduction gearing rotatably drivable by the drive shaft, a power distribution unit drivingly connected to the reduction gearing and configured to transmit a rotational motion to two output parts, a parking lock unit having a parking ratchet wheel which is connected in a rotationally fixed manner to a torque-transmitting member in the power path between the drive shaft and the output parts, and having a controllable locking element which can be selectively engaged with the parking ratchet wheel; wherein the parking lock unit is arranged in a parking lock housing which is liquid-tightly sealed with respect to a transmission housing so that a first oil bath in the transmission housing is separated from a second oil bath in the parking lock housing.

A hybrid transmission device (3) includes at least one electric motor (EM1, EM2), a first transmission input shaft (7), and a second transmission input shaft (9) mounted on the first transmission input shaft (7). A connecting clutch (K3) is configured for rotationally fixedly connecting the first transmission input shaft (7) and the second transmission input shaft (9). The second transmission input shaft (9) includes an end (11) facing toward the outer side of the hybrid transmission device (3) and an end (13) facing toward the inner side of the hybrid transmission device (3). The connecting clutch (K3) is arranged at the end (13) of the second transmission input shaft (9) facing toward the inner side of the hybrid transmission device (3).

The present invention relates to a method with which the driving dynamics of an electrically driven vehicle can be modified. Within the scope of the method according to the invention, a vehicle operating characteristic variable, as a function of which a torque transmission mechanism is engaged, is monitored, by means of which torque transmission mechanism two half-shaft assemblies of the vehicle which are each driven by an electric motor can be selectively connected to one another in terms of drive.

Methods and systems for a vehicle transmission are provided herein. The vehicle transmission includes an input interface configured to mechanically couple to a motive power source. The vehicle transmission further includes a first disconnect device releasably mechanically coupling a first output to a first drive axle and a second disconnect device releasably mechanically coupling a second output to a second drive axle.

A drive switching mechanism of a utility vehicle includes: a two-wheel drive and four-wheel drive switching device that switches between two-wheel drive and four-wheel drive of the utility vehicle; and a control unit that controls the drive switching mechanism. The two-wheel drive and four-wheel drive switching device switches between two-wheel drive and four-wheel drive by using a first clutch. The control unit permits the two-wheel drive and four-wheel drive switching device to switch from two-wheel drive to four-wheel drive when a rotation difference of the first clutch becomes equal to or smaller than a predetermined value.

A vehicle includes a first axle, a second axle, a driveshaft, a first clutch, a second clutch, a third clutch, and a controller. The second axle has first and second half shafts. The second axle has first and second wheels. The driveshaft is disposed between the first and second axles and is coupled to the second axle. The first clutch is configured to selectively couple the driveshaft to the first axle. The second clutch is configured to selectively couple the first wheel to the first half shaft. The third clutch is configured to selectively couple the second wheel to the second half shaft. The controller is programmed to control the clutches to connect the second axle to the first axle via the driveshaft.
