摘要： A fluid circuit for raising and lowering an implement including a quick drop valve member movable between at least a first position and a second position, the first position corresponding to a non-quick drop hydraulic fluid flow path of the fluid circuit and the second position corresponding to a quick drop hydraulic fluid flow path of the fluid circuit, the quick drop valve member being movable between at least the first and second positions based on pressures in the fluid circuit produced by hydraulic fluid. The fluid circuit further including a control system configured to selectively apply a biasing force against the quick drop valve member biasing the quick drop valve in the first position, the control system providing the biasing force independent of pressures in the fluid circuit produced by the hydraulic fluid.

摘要： A single lever control assembly that limits motion due to the inherent design of the assembly. In other words, no additional components are required to limit the motion of the single lever control assembly. The assembly includes two U-shaped members each having a base and parallel legs extending from the base, a lever connected to one of the U-shaped members and a pivot block interconnecting the parallel legs for allowing the U-shaped members to rotate relative to one another. The assembly has at least one of the parallel legs having a projection that engages one of the parallel legs of the other U-shaped member. In general, the single lever control assembly is a type of modified universal joint whose movement is limited by a projection.

摘要： A powertrain includes an engine, a transmission having a first input connected to an engine output shaft, and a variator. The variator includes a pump connected to the engine output shaft and a motor connected to a second input of the transmission. The pump has a variable setting that is determinable by a position of a pump actuator in response to a command signal. A controller associated is disposed to control operation of the variator, at least in part, by providing the command signal to the pump actuator. The command signal is determined based on an operator command and on a compensation term, which depends on a correlation function of a parameter related to the speed ratio between a pump speed and a motor speed and a flow characteristic of the pump actuator.

摘要： In an embodiment, torque control operation is provided in a transmission having a variable displacement variator with a hydraulic actuator. The transmission is engaged in a neutral state such that the variator output experiences substantially zero torque, and a first hydraulic pressure sweep to the hydraulic actuator is commanded while a corresponding sweep of motor speed ratio of the variator is recorded. The transmission is engaged into a locked mode providing a fixed output speed and a second hydraulic pressure sweep to the hydraulic actuator is commanded, and a corresponding sweep of variator output torque is recorded during this sweep. A torque/pressure map is then constructed relating motor torque, motor speed ratio, and actuator pressure by scaling the sweep of motor speed ratios and the sweep of variator output torque. The resultant map is usable to provide feed forward torque control of the transmission.
