摘要： A hydraulic pump is configured to mount within an internal receptacle defined by a housing of a hydraulically-powered component of a work vehicle. The pump has a housing defining one or more pump chambers. Each pump chamber communicates with a suction port and an outlet pressure port. Each pump chamber contains a pump assembly having a drive member at a fluid interface between the suction port and the outlet pressure port. The drive member is arranged for co-rotation with at least one power input component extending into the housing through each pump chamber. Rotation of each drive member displaces and pressurizes hydraulic fluid through the pump housing, and, when the pump is mounted within the internal receptacle, through internally ported passages routed through walls of the hydraulically-powered component housing.

摘要： Systems and methods are provided for a demand-based hydraulic system. A clutch is positioned between a hydraulic pump and an engine. The clutch is selectively engaged to power the hydraulic pump based on a level of demand for hydraulic power. A control system is also provided to control the clutch and/or the pump in accordance with a plurality of operating mode.

摘要： A suspension system for a work vehicle includes a first cylinder having a piston side, a second cylinder having a piston side, and a first valve connected to the first and second cylinders, which extend and retract during a roll condition of the suspension system. The first valve selectively enables and restricts fluid flow between the piston side of the first cylinder and the piston side of the second cylinder to adjust a roll resistance of the suspension system.

摘要： An axle suspension supports an axle housing on a vehicle frame. The suspension includes left and right pivot rods attached to left and right frame members. A suspension arm has a first end fixed to a rear end of the axle housing and has a second end pivotally coupled to the left and right pivot rods. A variable length left hydraulic cylinder has an upper end pivotally coupled to the left frame member and has a lower end pivotally coupled to a front end of the axle housing. A variable length right hydraulic cylinder has an upper end pivotally coupled to the right frame member and has a lower end pivotally coupled to the front end of the axle housing. The left and right hydraulic cylinders are hydraulically connected in parallel.
