Abstract: A wheel head transmission (1) comprising a first and second shafts (W1, W2) which are connected to one another via a planetary transmission (PG). The wheel head transmission (1) comprises first and second planetary stages (P1, P2), which include a first element (E11, E12), a second element (E21, E22) and a third element (E31, E32). The first element (E11) of the first planetary stage (P1) is connected to the first shaft (W1) for conjoint rotation, the second element (E21) of the first planetary stage (P1) and the third element (E32) of the second planetary stage (P2) are connected to one another and the second shaft (W2) for conjoint rotation. The third element (E31) of the first planetary stage (P1) and the first element (E12) of the second planetary stage (P2) are connected together for conjoint rotation, and the second element (E22) of the second planet stage (P2) is immobilized.

Abstract: A drive assembly 1 for a vehicle includes a prime mover housing section 2 and a transmission housing section 3. The prime mover housing section 2 encompasses a dry space 4, and the transmission housing section 3 encompasses an oil space 5. The oil space 5 is at least partially filled with an oil 6. A prime mover shaft 10 extends from the dry space 4 into the oil space 5. A partition 7 separates the oil space 5 from the dry space 4. A sealing device 13 seals the prime mover shaft 10 with respect to the partition 7. The sealing device 13 is arranged in the partition 7. A connecting unit 19 provides a fluidic connection between and compensates for pressure differences between the oil space 5 and the dry space 4.

Abstract: An air infeed device for air-conditioning passenger areas in aircraft includes a central air infeed module for the centrally regulated cabin ventilation system and an individual air infeed module for the individually adjustable cabin ventilation system. The centrally regulated cabin ventilation system and the individually adjustable cabin ventilation system are mutually independent systems. The central air infeed module and the individual air infeed module are connected to form a subassembly that can be handled independently as a collective unit.

Abstract: A pipe connecting device (10) for connecting two pipeline portions (12, 14) of an aircraft pipeline system comprises a bridge portion (16), the cross-sectional form of which is matched to a cross-sectional form of the pipeline portions (12, 14) that are to be connected to each other. The pipe connecting device (10) further comprises a first receiving portion (18), which is constituted by two limbs (20, 22) extending from the bridge portion (16) in a first direction, and which is adapted to receive an edge portion (38) of a first pipeline portion (12) of the aircraft pipeline system, and a second receiving portion (24), which is constituted by two limbs (26, 28) extending from the bridge portion (16) in a second direction opposite to the first direction, and which is adapted to receive an edge portion (40) of a second pipeline portion (14) of the aircraft pipeline system.
