摘要： A solenoid fluid control valve is disclosed for controlling fluid flow. The solenoid fluid control valve may comprise a transceiver that receives a signal via a controller area network (CAN) bus, and a micro controller unit that decodes the signal to determine a temperature. The micro controller unit may send a signal to a driver circuit based on the temperature. The driver circuit may send a current through a coil in response to the signal, wherein an armature moves in response to the current through the coil. The movement of the armature may direct a cooling fluid flow.

摘要： Provided is a work vehicle that does not have any torque converter, and that can raise the temperature of the hydraulic oil of a clutch when the work vehicle starts. The work vehicle includes a transmission, a hydraulic oil supply circuit, a hydraulic oil warming circuit, and a control unit. The hydraulic oil supply circuit is configured to supply hydraulic oil to the transmission. The hydraulic oil warming circuit is configured to warm up the hydraulic oil. The control unit is configured to control the transmission, the hydraulic oil supply circuit, and the hydraulic oil warming circuit. The transmission includes a hydraulic clutch and a clutch control valve. The clutch control valve is configured to control the pressure of the hydraulic oil supplied to the hydraulic clutch according to a command from the control unit. When the control unit determines that the temperature of the hydraulic oil is low, it is configured to output a warming up command for operation of a warming up function. And the hydraulic oil warming circuit is configured to warm up the hydraulic oil by causing the pressure loss in a flow path for the hydraulic oil.

摘要： Inventive embodiments are directed to components, subassemblies, systems, and/or methods for a refrigeration system having a compressor operably coupled to continuously variable accessory drive (CVAD). In one embodiment, the refrigerant is adapted to cool the CVAD. In another embodiment, the refrigerant is configured to actuate a change in operating condition of the CVAD. A change in operating condition of the CVAD can be based at least in part on the thermodynamic state, such as pressure or temperature, of the refrigerant. In one embodiment, a skew-based control system is adapted to facilitate a change in the ratio of a CVAD. In another embodiment, a skew-based control system includes a skew actuator coupled to a carrier member. In some embodiments, the skew actuator is configured to rotate a carrier member of a CVT. Among other things, shift control interfaces for a CVT are disclosed.

摘要： An eccentric rocking type reduction gear capable of being effectively cooled by an extremely simple structure. The eccentric rocking type reduction gear (1) has a camshaft (11) having crank parts (11a, 11b), externally toothed gear members (12) having holes for receiving the crank parts and eccentrically moved by rotation of the camshaft, an internally toothed gear member (13) meshed with external gear teeth formed on the outer peripheral surfaces of the externally toothed gear members and having internal gear teeth that are formed on the inner peripheral surface of the internally toothed gear member and are slightly greater in quantity than the external gear teeth, and support members (14) positioned at both ends of the externally toothed gear members and rotatably supporting the both ends of the camshaft. Support members (18, 19) are integrally connected to each other through a column part (17). A cooling medium passage (30) is formed in a manner penetrating through the integrally connected support members (18, 19) and through the column part (17), and a cooling medium, such as cooling water and cooling air, is passed through the cooling medium passage. Consequently, the eccentric rocking type reduction gear can be efficiently cooled.
