  • Publication number: 20110118070
    Abstract: A transmission device (1) having a transmission housing (2) in which several assemblies can be positioned for creating different gear ratios, and a start-up device, preferably a hydrodynamic torque converter. At least one breakout (3, 13) is provided in the wall area of the transmission housing (2), where the edge areas (4) are designed as stiffening zones and through which the torque is brought from the transmission housing (2) to auxiliary drive trains. In the area (5) of the transmission housing (2), which is designated for a start-up device, at least one electric machine (6) of a hybrid system is provided. A connection of the electric machine (6), which is positioned in the transmission housing (2), to power electronic located external of the transmission housing (2), is brought through the at least one breakout (13) of the transmission housing (2).

  • Publication number: 20110100736
    Abstract: A hybrid drive train for a motor vehicle comprises an internal combustion engine, and electric machine, with a stator and rotor, and a transmission. A disk clutch is located in the force flow, between the combustion engine and the transmission input shaft, and an outer disk carrier of the disk clutch is fixed to a transmission input stage and an inner disk carrier of the disk clutch is connected to the combustion engine. The rotor of the electric machine drives another element of the transmission input stage, and the disk carriers of the clutch are mounted and centered by two roller bearings which center the inner and outer disk carriers relative to one another and bring them into axial alignment, and axial tolerances within the unit which comprises the electric machine, the separator clutch and the transmission input stage are compensated by displacing and aligning the disk packet of the clutch in the drive gearing of the inner disk carrier.

  • Patent number: 6626059
    Abstract: The invention relates to a transmission with torque division for a helicopter rotor drive. In a manner known per se, in the transmission a first power transmission branch has a first rotatable driving pinion (6) which is in constant engagement with a first toothed wheel (2) on the output side. At least one other power transmission branch has one other driving pinion (9) co-axial to the first driving pinion (6) and in constant engagement with one other toothed wheel (4) on the output side co-axial to the first toothed wheel (2) on the output side. One torsionally elastic member is arranged in the torque flow of each power transmission branch. The torsion-resistance of the torsionally elastic members determines the load proportions of the power transmission branches. The inventive transmission makes possible a high power density with small installation space, light weight and a small number of functional elements.

  • Patent number: 6487923
    Abstract: The multi-speed boat transmission for propulsion systems having a basic transmission for transmitting the motor power to a fixed propeller or water jet has, in addition to a preferably single-speed basic transmission (2), a separate front-mounted transmission (1) for flange-mounting to the basic transmission (2) and stepping-up parts (7, 8, 12), the countershafts (5) being distributed around the periphery of the main shaft (10) of the basic transmission in a manner such that no additional forces act upon the main shaft (10).

  • Patent number: 6478715
    Abstract: According to the method for controlling at least one power-shift multi-speed boat transmission in conjunction with a fixed propeller or water jet, the upshift speed is a function of a value which indicates the intended acceleration, especially a function of the regulating speed of the control lever or the speed of modification of the transmission input speed.

  • Patent number: 6224017
    Abstract: A brake for a flap adjusting mechanism and a method for condition monitoring are proposed. The brake has one or more temperature sensors (30). In the method for condition monitoring, the temperature signal is compared with a desired temperature (T1, T2) in the signal processing unit in a time period during or after a rotation of the driveshaft (2) in the housing (4) while expending the braking moment. An error signal is produced in case of deviations of the temperature signal from the desired temperature.

  • Patent number: 5966997
    Abstract: A device for transmitting linear motion for adjustment of a wing element (4) is provided with one input part (23) and one output part (26) wherein between the input part (23) and the output part (26) an uncoupling mechanism is provided which, above a preset force (release force) makes relative motion between the input part and the output part possible. One or more prestressed springs (42), which can absorb energy during relative motion, upon unloading, restores the input and output parts to an initial position. A translation mechanism converts the relative motion between the input part (23) and the output part (26). The converted motion acts upon the spring (42) whereby a force-path characteristic line of the device, corresponding to the translation mechanism, can be obtained. The translation mechanism consists of a crankshaft (52) with cam discs (50A, 50B) driven by a connecting rod (46) which act upon a piston (48) longitudinally movable within the housing (30) and prestressed by springs (42).
