Abstract: A gearbox parking brake has a gearing assembly in which two or more interconnected gears can rotate at different directions or speeds. A first and second planetary gear assembly and a central gear are concentrically positioned about a central rotation axis, and the central gear is rotatably engaged with the two planetary gear assemblies. An input is engaged with the central gear in order to operate the planetary gear assemblies, which may function as outputs. A gear engagement block is provided with sets of gear teeth corresponding to the planetary gear assemblies and the central gear. An actuator mechanism is operatively connected to the gear engagement block in order to displace the gear engagement block between a disengaged position and an engaged position. The gear teeth of the gear engagement block are meshed with the gearing assembly in the engaged position, restricting any movement of the gearing assembly.

Abstract: 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.
