摘要： A vehicle transmission housing has first and second axle housings pivotably connected to opposite ends of the transmission housing and a stand-on platform may be connected to the assembly. A first gear train in the first axle housing drives a first axle having a first axis of rotation. A second gear train is disposed in the second axle housing drives a second axle having a second axis of rotation collinear with the first axis of rotation. The axle housings are both capable of pivoting about the transmission housing about a third axis that is parallel to the first and second axes. The first and second axle housings may also be separately rigidly or flexibly connected to one another. This assembly permits adjustment of the ground heights of the platform with respect to a vehicle frame.

摘要： A port plate for use in an integrated drive generator has a body defining a semi-cylindrical charge port communicating with two circumferentially smaller charge port portions. A diametrically opposed working pressure port has three smaller working pressure ports. A center plane is defined extending through a center axis of a bore within the body and equidistance between circumferential ends of the charge port and the working fluid port. A first angle is defined between the plane and a circumferential end of the smaller charge port. The first angle is between 15 and 25 degrees. An integrated drive generator and a method are also disclosed.

摘要： The present disclosure relates to a hydro-mechanical transmission having two rotating groups that mount on a common shaft. At least one of the rotating groups operates as a variable displacement pump or motor. At least one of the rotating groups interacts with a torque transfer unit rotatable about the shaft axis relative to both the shaft and the rotating group. The torque transfer unit includes a valve plate, a swash plate and a torque output section that all rotate in unison with one another about the shaft axis relative to the shaft and the rotating group. The valve plate includes an inlet passage for inletting hydraulic fluid to the rotating group and an outlet passage for outletting hydraulic fluid from the rotating group.

摘要： A hydrostatic transaxle with a bypass mechanism is disclosed, the transaxle having a center section engaged to a housing, an axial piston pump disposed on the center section and driven by an input shaft, and an axial piston motor disposed on the center section having a cylinder block engaged to a motor output shaft. The pump is controlled by a swash plate having a pair of openings through which the input shaft and a bypass actuation rod pass. The bypass actuation rod has a cam formed on a first end that engages a block lift member. When the bypass actuation rod is rotated, the cam causes the block lift member to engage and lift the cylinder block of the axial piston motor off of the center section. A brake mechanism using brake puck disposed in a pocket formed in the center section is also disclosed.
