Drive assembly with pressure force aggregating piston arrangement for hydraulic motor speed/torque selector
A drive assembly includes a drive motor at least in part contained in a housing and having a rotor rotating an output shaft. A selector mechanism, at least in part contained in the housing, is movable into one of a plurality of orientations corresponding to one of a plurality of drive motor settings. An actuator, at least in part contained in the housing, is arranged to move the selector mechanism into one of the plurality of orientations. The actuator has first and second pistons each disposed in a piston chamber of the housing for movement by hydraulic pressure. The second piston is arranged in contact with the first piston and configured to aggregate and transfer forces from hydraulic movement of the first piston and the second piston to move the selector mechanism.
Axle assembly with hydraulically-operated disconnect mechanism and spin-on hydraulic filter
An axle assembly can include a housing defining a reservoir and cylindrical bore open thereto. A clutch can selectively transmit torque between input and output members. A first inlet/outlet of a pump can be in fluid communication with the reservoir and define first threads coaxial with the cylindrical bore. The pump can be configured to pump fluid from the first inlet/outlet to an actuator of the clutch via a second inlet/outlet. The filter can include a base, port, and filter element. The port can define second threads that threadably engage the first threads. The base can be fixedly coupled to the port and include a cylindrical wall coaxial with the second threads. A seal member can form a seal between the cylindrical wall and the cylindrical bore when the first and second threads are engaged. The filter element can be disposed between the reservoir and the first inlet/outlet.
Agricultural Vehicle having a Pivotable Cab
An agricultural machine, preferably a combine harvester, which has a pivoting vehicle cab. The cab is pivotable relative to the main frame of the machine, about an axis of rotation transverse to the direction of travel of the machine. The cab is pivoted to allow an operator to view a front coupling of the machine, to observe the attaching or detaching of a work implement to the front coupling.
Axle assembly having a clutch collar actuator mechanism
An axle assembly having a clutch collar actuator mechanism. The clutch collar actuator mechanism may have a piston housing and a yoke that may move with respect to the piston housing. The piston housing may extend around the input shaft and may receive at least one piston. The yoke may connect the piston to the clutch collar.
Hydraulic mode-stable powertrain transfer case
A transfer case (26) for translating rotational torque from an engine (22) to first and second differentials (34, 36). A primary shaft (50) is supported in a housing (48) and has an input in communication with the engine (22) and an output in communication with the first differential (34). A secondary shaft (52) is disposed in communication with the second differential (36). A clutch (54) selectively translates torque between the shafts (50, 52) and moves between a first position (54A) wherein torque is translated to the secondary shaft (52), and a second position (54B) wherein torque is interrupted. An actuator (64) with a piston (68) movably supported in a cylinder (66) moves the clutch (54). A lock (70) moves between a locked configuration (70A) engaging the piston (68) to prevent the clutch (54) from moving, and an unlocked configuration (70B) releasing the piston (68) allowing the clutch (54) to move.
COOLING AND LUBRICATION SYSTEM INCLUDING 3-WAY SOLENOID-ACTUATED VALVE FOR AUTOMATIC TRANSMISSION
A system for use in an automatic transmission includes a 3-way solenoid-actuated valve includes a valve body having an inlet port and a first outlet port and a second outlet port, a valve disposed within the valve body and slidably controllable to proportion flow between the first outlet port and the second outlet port, and a spring disposed in the valve body to bias the valve for flow toward the second outlet port. The system also includes at least one pump providing fluid to the inlet port, a first fluid circuit connected to the first outlet port providing fluid to a first subsystem of the automatic transmission, and a second fluid circuit connected to the second outlet port providing fluid to a second subsystem of the automatic transmission.
WORK VEHICLE WITH REMOTE BRAKE RELEASE
The present disclosure is directed to a braking system for a work vehicle having hydraulically-actuated brakes. The braking system includes a primary release valve, a secondary release valve, and at least one braking mechanism having one or more brake springs. The braking mechanism(s) is hydraulically coupled to the primary release valve and the secondary release valve via one or more hydraulic lines. As such, during full-power operation of the work vehicle, when the brakes are to be released, the primary release valve is energized so as to overcome a valve biasing spring, thereby shifting the primary release valve so as to direct pressurized hydraulic fluid to the braking mechanism(s). Further, when the brakes are to be applied, the primary release valve is inactive so as to allow the hydraulic fluid to flow away from the braking mechanism(s) to a primary reservoir such that the one or more brake springs compress the braking mechanism(s). Alternatively, when power is lost to the work vehicle, the secondary release valve bypasses the primary release valve and directs pressurized hydraulic fluid to the braking mechanism(s) to release the brakes.
BICYCLE TELESCOPIC APPARATUS
A bicycle telescopic apparatus includes a first tube, a second tube, an actuating member, and a hydraulic positioning structure. The first tube defines an axial direction. The second tube is telescopically received in the first tube in the axial direction. The actuating member is movable relative to the first tube in the axial direction of the first tube. The actuating member is configured to move the second tube relative to the first tube in the axial direction. The hydraulic positioning structure is configured to position the first tube and the second tube relative to each other in the axial direction.
Gliding Pivot
A cover system includes a cover, two bail arms, and a fluid circuit. Each bail arm is mounted on a gliding assembly. Each gliding assembly includes a gliding body slidably supported on a vehicle frame, and a cylinder connected to the gliding body and defining first and second ends. The fluid circuit is configured to supply fluid to the first end of the first cylinder and the second end of the second cylinder. A fluid line connects the second end of the first cylinder to the first end of the second cylinder and is configured to direct the fluid between the cylinders such that a flow of the fluid to the first cylinder causes movement of the cylinders, gliding bodies, and bail arms in a first direction, and a flow to the second cylinder causes movement of the cylinders, gliding bodies, and bail arms in a second opposite direction.
Front End Motor-Generator System and Hybrid Electric Vehicle Operating Method
A system and method are provided for hybrid electric internal combustion engine applications in which a motor-generator, a narrow switchable coupling and a torque transfer unit therebetween are arranged and positioned in the constrained environment at the front of an engine in applications such as commercial vehicles, off-road vehicles and stationary engine installations. The motor-generator is preferably positioned laterally offset from the switchable coupling, which is co-axially-arranged with the front end of the engine crankshaft. The switchable coupling is an integrated unit in which a crankshaft vibration damper, an engine accessory drive pulley and a disengageable clutch overlap such that the axial depth of the clutch-pulley-damper unit is nearly the same as a conventional belt drive pulley and engine damper. The front end motor-generator system includes an electrical energy store that receives electrical energy generated by the motor-generator when the coupling is engaged. When the coupling is disengaged, the motor-generator may drive the pulley portion of the clutch-pulley-damper to drive the engine accessories using energy returned from the energy store, independent of the engine crankshaft.
