초록 ▼

Front and rear wheeled units of vehicle are connected together for articulated steering. Wheels on at least one unit are mounted for swivelling relative to the respective unit to provide kingpin steering in combination with articulation steering. A first embodiment has front and rear kingpin steering and articulation steering performed manually and independently of the each other. In a second embodiment, a steering integrator cooperates with actuators which control at least the articulation steering and kingpin steering of the front wheels to automatically integrate two types of steering so that a controlled relationship exists between an articulation angle of the front unit with respect to the rear unit, and swivel angles of the front wheels with respect to the front unit. A manual steering control, e.g. a steering wheel, controls actuation of the steering integrator. Each wheel is powered by a hydraulic motor receiving pressurized fluid from a drive apparatus comprising a flow combiner and two flow restrictors connected in parallel with each other and communicating with outlets from the wheel motors. Isolating valves can be used to isolate the flow combiner and flow restrictors as needed in certain applications not requiring the flow combiner, to reduce generation of heat in the hydraulic fluid.

대표청구항 ▼

A vehicle hydraulic drive apparatus comprising: (a) a pressurized hydraulic fluid source having a discharge which discharges pressurized fluid under a relatively high pressure, and a return which scavenges fluid under a relatively low pressure, (b) at least one pair of right hand and left hand wheel motors, each motor having a fluid inlet and fluid outlet, each inlet communicating with the discharge of the fluid source when the vehicle is driven forwardly, (c) right hand and left hand isolating valves, each valve communicating with the outlet of the respective motor and the return of the pressurized hydraulic fluid source when the vehicle is driven forwardly, (d) right hand and left hand flow restrictors, each restrictor communicating with the outlet from the respective motor, and the return of the pressurized fluid source when the vehicle is driven forwardly, and (e) a flow combiner having right hand and left hand inlets communicating with the outlets from the right hand and left hand wheel motors respectively, and an outlet communicating with the return of the fluid source when the vehicle is driven forwardly.
