The present invention relates to a transmission assembly (20) for a drive (5) of a work apparatus (4) having a planetary transmission (21) and a brake device (23) arranged coaxially with respect thereto. The planetary transmission (21) has a drive shaft (19), which can be braked by the brake device (23), and an output (5), which is operatively connectable mechanically to the work apparatus (4). The brake device (3) has a flange (34), which faces away from the planetary transmission (21), for the mounting of an electric motor (17). The drive shaft (19) of the planetary transmission (21) extends through the brake device (23) in order to be mechanically driveable by an electric motor (17) attached to the flange (34) of the brake device (23).

Disclosed is a test rig (1) for testing vehicle tires. In one embodiment, the test rig includes a rotating drum (2) on a drum axle (3) and force pick-ups (4, 5, 6) for the determination of a radial force acting on the drum axle (3) and a lateral force acting on the drum axle (3). In one embodiment, the test rig (1) has three uniaxial force pick-ups (4, 5, 6), such that a first and a second force pick-up (4, 5) are arranged so as to determine a radial force, where a third force pick-up (6) is arranged so as to determine a lateral force, and where the first force pick-up (4) and the third force pick-up (6) are coupled. Also disclosed is a method for testing vehicle tires.

ASSEMBLY FOR A GEARBOX FOR A WIND TURBINE, ARRANGEMENT, KIT, GEARBOX FOR A WIND TURBINE, METHOD FOR TRANSPORTING AN ASSEMBLY FOR A GEARBOX AND METHOD FOR ASSEMBLING A WIND TURBINE
In at least one embodiment, the assembly (10) for a gearbox (11) for a wind turbine comprises a housing element (1), a rotational element (2), a bearing (3), a first connection feature (41) for connecting the housing element to a connection element and a second connection feature (42) for connecting the rotational element to the connection element. The rotational element is arranged rotatably with respect to the housing element by means of the bearing. At least one of the first and the second connection feature is configured to form a movable, form-fitting connection such that, when the housing element and the rotational element are connected to the connection element by means of the first and the second connection feature, a relative axial movement between the rotational element and the housing element is prevented but a relative rotation between the rotational element and the housing element is enabled.
An emergency release of a parking lock of a vehicle transmission arranged in a transmission housing 9 includes an actuating element of an actuator for actuating the parking lock is drivable so as to be linearly movable between an interlock position and a release position. The emergency release lever 3 is pivotable away from a normal position past an emergency release position into an installation position and, in a second end region, has two guide projections 15, 16, which are parallel to each other and extend radially toward the pivot pin 7, and between which a securing projection 10, which is fixedly connected to the transmission housing 9, projects when the emergency release lever 3 is in the normal position and in the emergency release position. In the installation position of the emergency release lever 3, the securing projection 10 is located outside the area between the two guide projections 15, 16 on the emergency release lever 3.
A method for controlling an actuatable safety device for protecting an occupant of a vehicle includes sensing a left upfront vehicle acceleration via a left upfront sensor, sensing a middle upfront vehicle acceleration via a middle upfront sensor, and sensing a right upfront vehicle acceleration via a right upfront sensor. The method also includes sensing a central vehicle acceleration via a central airbag control unit. The method further includes determining the occurrence of a vehicle crash event in response to determining that each of the left, middle, and right upfront vehicle accelerations exceeds a predetermined magnitude and is phase shifted from the central vehicle acceleration.
