  • Patent number: 6907728
    Abstract: A load sensing hydraulic system includes two pumps, at least one hydraulic fluid consumer, and a pressure balance circuit. In the case of no demand from the consumer, hydraulic fluid flows from the pumps through the pressure balance circuit and to tank. In the case of demand from the consumer for hydraulic fluid at a flow rate less than or equal to the flow rate provided by the first pump, hydraulic fluid from the first pump flows to the consumer, and hydraulic fluid from the second pump flows to the tank. In the case of a demand from the consumer for hydraulic fluid at a flow rate greater than the capacity of the first pump, hydraulic fluid from both pumps flow to the consumer.

  • Patent number: 6878176
    Abstract: A vehicle includes an operator's cab having an air inlet and an air filtration system, and an air outlet, wherein the air filtration system comprises a filter element, and a filter container for receiving the filter element, the operator's cab comprising a chamber for receiving the filter container housing the filter element, the filter container being movable into and out of the chamber between a filtering position and an emptying position, wherein with the container in the emptying position the filter element may be removed from the container, and the container emptied of debris, and wherein the filter container comprises at least one air inlet opening and at least one air outlet opening, and wherein with the container in the filtering position the openings are aligned with the air inlet and air outlet such that air may be drawn through the filter into the cab.

  • Patent number: 6377192
    Abstract: In an electronic control system for controlling the setting of two or more continuously variable parameters, the system comprises a hand operated lever and electronic processing means 14 having an input from the lever 1 and output means for outputting a signal or signals representative of the said continuously variable parameters, characterised in that: a) the lever 1 is arranged in a gate having two substantially parallel slots 3-5 and a transverse slot 6, the position of the lever 1 in each of the two parallel slots being substantially continuously variable and corresponding to a desired value for one or more of the said continuously variable parameters; b) the processing means includes means 14 for storing a record of the position of the lever 1 in one of the said slots after the lever has been removed from the slot.

  • Patent number: 6167341
    Abstract: A vehicle road speed control system includes a vehicle road speed detection means, parameter storage means, comparator processing means and control signal generation means. The system is arranged to compare measured vehicle road speed with predetermined road speeds obtained from stored parameters. When an upper threshold road speed is exceeded a control signal is generated for an associated transmission control system which causes the operative ratio of an associated vehicle transmission to be reduced such that the vehicle road speed is reduced to at least the upper threshold road speed. The road speed may also be controlled by altering the characteristics of an associated fuel injection such that the road speed is reduced to at least the upper threshold road speed. This may be done in place of controlling the operative ratio of the transmission or in addition.

  • Patent number: 5722167
    Abstract: A bearing comprises an inner race, an outer race and rolling members interposed between the inner and outer races with a radial clearance c, greater or equal to zero, remaining. The bearing also comprises a partial sealing member attached to either the inner race or the outer race to one side of the rolling members and which defines a substantially annular chamber between the partial sealing member and the outer race or the inner race respectively. The substantially annular chamber has a length L and a width j and the width j is fractionally greater than the radial clearance c.The partial sealing member may be formed integrally with either the inner race or the outer race or it may be formed separately and subsequently attached to either race as appropriate. The rolling members may be in any appropriate form, for instance balls or rollers.
