摘要： An embodiment of the present invention involves a zero turn drive apparatus. The zero turn drive apparatus has a housing, which has a first and a second end. The housing has a first end cap mounted on the first end of the housing, and a second end cap mounted on the second end of the housing. A hydraulic pump is rotatably mounted on each end cap, and each hydraulic pump is driven by a pump input shaft. A gear chamber is interposed between each pump. A power take off mechanism is engaged to the housing, and an output shaft extends from the power take off mechanism. An input shaft, which is engaged to each of the pump input shafts, extends into the power take off mechanism and is selectively engaged to the output shaft.

摘要： A charge pump design for a hydraulic drive apparatus such as a hydrostatic transmission, integrated hydrostatic transaxle or pump having a rotatable pump cylinder block mounted in a sump and connected to a hydraulic circuit by means of a center section or the like. A fluid gallery for charge fluid is in communication with the hydraulic circuit and the charge pump is mounted adjacent to and is driven by the pump cylinder block to provide hydraulic fluid from the sump to the fluid gallery. The charge pump can be of many different styles such as a gerotor, a centrifugal pump or a flexible impeller style.

摘要： An expansion sump is provided in the axle horn of a hydraulic apparatus, and a cap member seals the expansion sump from the main sump. An arcuate sealed fluid passage is provided between the periphery of the cap member and the housing. The sealed fluid passage cooperates with a first passage between the expansion sump and the sealed fluid passage and a second passage between the main sump and the sealed fluid passage to form a siphon to permit fluid communication between the two sumps. The hydraulic apparatus may also have an oil filter removably mounted on the external surface of the housing and a removable shield adjacent thereto, with an engagement member formed on the shield to prevent the oil filter from being removed from the housing with the shield in place.
