摘要:
A vehicle 10 includes a prime mover engine 15, a drive wheel 16, and a hydrostatic transmission 20. The prime mover engine 15 has a substantially vertical prime mover output shaft 18. The hydrostatic transmission 20 has a hydraulic pump 24 with a substantially vertical pump input shaft 28. A drive link 31 drivingly connects the pump input shaft 28 to the prime mover output shaft 18. The hydraulic motor 25 has a substantially vertical output shaft 30. An interface connector 32 establishes fluid pressure communication between the hydraulic pump and the hydraulic motor. A gear set is intermediate the hydrostatic transmission 20 and drive wheel 16. The gear set includes a vertically disposed bevel gear 41 drivingly connected to the motor output shaft 30 and a horizontally disposed bevel gear 42 drivingly connected to the drive wheel 16.

A continuously variable transmission (CVT) for a vehicle includes a hydraulically-controlled component and a pilot valve. The pilot valve includes at least one micro-electrical-mechanical-systems (MEMS) based device. The pilot valve is operably connected to and is configured for actuating the hydraulically-controlled component. The pilot valve additionally includes a regulating valve operably connected to the pilot valve and to the hydraulically-controlled component. The regulating valve is configured to direct fluid to the hydraulically-controlled component when actuated by the pilot valve.

An automatic transmission device for an automobile includes a torque converter accommodated in a torque converter housing, a stator shaft supporting a stator of the torque converter, a torque converter housing, a stator shaft supporting a stator of the torque converter, a torque converter sleeve provided concentrically with the stator shaft and coupled with an inner periphery side of an impeller shell of the torque converter, a first bearing provided between an inner peripheral surface of the torque converter sleeve and an outer peripheral surface of the stator shaft, and a second bearing provided between an outer peripheral surface of the torque converter sleeve and an inner surface of the torque converter housing.
摘要:
A drive apparatus driven by a prime mover that has a prime mover output shaft is disclosed. The drive apparatus has a housing and a power take off. The power take off is driven by the prime mover output shaft and selectively drives a power take off output shaft. The drive apparatus further has a variable speed transmission disposed within the housing. The variable speed transmission drives a transmission output shaft, which in turn drives a first clutch mechanism and a second clutch mechanism. A first drive axle is engaged to and selectively driven by the first clutch mechanism and a second drive axle is engaged to and selectively driven by the second clutch mechanism.

A device (2) for a vehicle drivetrain (1) with a transmission unit (3) for changing various transmission ratios. The device (2) comprising a reversing gear system (4) arranged on an input side of the transmission for reversing the rotational direction. A hydrodynamic torque converter device (5) located upstream of the reversing gear system (4). A hydraulic device (6) which, in the power flow direction is located between the reversing gear system (4) and the transmission unit (3) and can be brought into active connection with them for producing a torque that can be applied in the area between the reversing gear system (4) and the transmission unit (3).

A gearbox includes an input shaft connected to a rotor hub, an output shaft connected to a generator, and a first gear wheel rotation-locked to the input shaft and arranged inside a gearbox housing. A second gear wheel arranged inside the gearbox housing and meshing with the first gear wheel or coupled thereto via one or more additional gear wheels is rotation-locked to the output shaft. A flange radially surrounds the input shaft and/or the output shaft and has a circumferential groove on a side facing the input shaft and/or output shaft. An annular tubular sealing element made from an elastic material is fixed in the circumferential groove and can be expanded by an increase in the internal pressure. An intermediate space between the input shaft and/or output shaft and the circumferential groove is thus completely sealed by the sealing element when expanded.

A variable ratio gear system is configured for use with a constant speed generator being driven by a variable speed rotor. The variable ratio system includes three shafts: The first shaft is mechanically coupled to the rotor; the second shaft is mechanically coupled to a variable gear system; and the third shaft is mechanically coupled to the generator and the variable gear system. A control system is configured to adjust the output of the variable gear system to control the rotational speed of the generator. A brake is configured to control the rotation of the second shaft.
