    摘要: An apparatus (10) is provided for automatically actuating a brake system (28) in a work vehicle. The work vehicle has an engine (12) and a plurality of ground engaging wheels (24). At least one of the wheels (24) is driven by the engine (12) for propelling the vehicle. The brake system (28) is provided for opposing motion of at least one of the wheels. The apparatus (10) includes speed sensor (20) for sensing actual engine speed and responsively producing an actual engine speed signal. A controller (64) receives the actual engine speed signal and produces an error signal in response a difference between the actual and desired engine speed signals. The controller (64) further produce a control signal in response to the error signal. An actuator (76, 52, 58) is provided for receiving the control signal and controlling the braking force applied by the brake system (28) so as to reduce the error signal to zero.

    摘要: An electronic control is provided for controlling the drive speed of a supplemental drive relative to an engine driven main drive of a vehicle. A fluid pump driven by the engine provides pressurized fluid flow. The supplemental drive is driven by the pressurized fluid. A main drive sensor senses the speed of the main drive and responsively produces a main drive speed signal. A command knob is provided for selecting a desired speed relationship between the main and supplemental drives. A knob sensor senses the position of the command knob and responsively produces a modifier signal. A modifier circuit receives the main drive speed and modifier signals and responsively produces a modified main drive speed signal. A supplemental drive sensor senses the speed of the supplemental drive and responsively produces a supplemental drive speed signal. A processor produces an error signal responsive to a difference between received modified main and supplemental drive speed signals. The processor produces a first signal responsive to a product of the error signal and a preselected constant, produces a second signal responsive to an integral of the error signal, produces a third signal responsive to a derivative of the error signal and produces a pump control signal in response to a sum of the first, second, and third signals. An actuator receives the pump control signal and responsively adjusts the pump output.

    摘要: An electronic control is provided for a vehicle having an engine, a main drive driven by the engine, a fluid pump driven by the engine for providing pressurized fluid, and a supplemental drive driven by the pressurized fluid. The electronic control includes a main drive sensor for sensing the speed of the main drive and responsively producing a main drive speed signal. A vehicle speed sensor senses the speed of the vehicle relative to the ground and produces a vehicle ground speed signal. A pressure sensor senses the pressure of the pressurized fluid supplied to the supplemental drive by the pump and responsively produces an actual pressure signal. A processor receives the main drive speed, vehicle ground speed, and actual pressure signals, produces a slip ratio signal responsive to a ratio of the main drive speed and vehicle ground speed signals, produces a desired pressure signal responsive to the slip ratio signal, produces an error signal responsive to a difference between the desired and actual pressure signals, and controls the fluid pressure in the supplemental drive in response to the error signal.

    摘要: A roll of sheet material is supported on two spaced apart support rollers. During each dispensing cycle, the angular displacement of one of the support rollers is limited by a mechanism which includes a rotary member and a pivoted member. The rotary member carries a projection and is driven in an amount proportional to the amount of support roller movement. The pivoted member has an abutment surface and a reset surface. The abutment surface and the reset surface are positioned so the projection approaching the pivoted member contacts the abutment surface before coming to the reset surface. The abutment surface lies in the path of the projection to stop rotation of the rotary member and thus stop dispensation of the sheet material. A handle moves the pivoted member to withdraw the abutment from the projection path and to move the reset surface into the projection path. Movement of the projection against the reset surface moves the pivoted member to bring the handle over-center and return the abutment surface to its projection-abutting position where it will stop the movement of the rotary member upon completion of one revolution. This stops dispensation of sheet material until the handle is operated again to withdraw the abutment from the projection path.
