Title: Improvements in or relating to Vehicles
IPC: B62D11/08
Filed: 1968-05-27
Abstract: 1,155,679. Controlling vehicles. INTERNATIONAL HARVESTER CO. 27 May, 1968 [29 May, 1967], No. 25220/68. Heading B7H. [Also in Division F2] A vehicle has an engine 30, a transmission system 16, shifttable between forward, neutral and reverse conditions, braking means 56 and a control system in which control signals are produced responsive to forward and reverse transmission shift conditions and to forward and reverse movement of the vehicle and in which the simultaneous presence of control signals indicative of movement in one direction and the opposite transmission shift condition is effective to operate the braking means 56 and to prevent the transmission of power to drive the vehicle. When the transmission 16 is put into its forward or reverse shift condition from the neutral condition shown by operation of a control valve speed 18 by a shift lever 22, a sensing valve 103 directs pressure fluid from a hydraulic pump 24 and conduits 25, 106 either through a conduit 108 to a forward shift servomotor 110 or through a conduit 112 to a reverse shift servomotor 114 moving the respective piston 118 and spool valve 122 to the the right. On forward or reverse vehicle movement a gear pump 68 supplies hydraulic fluid a from reducing valve 72 respectively to forward or reverse movement servomotors 88 and 96. When two adjacent servomotors are actuated simultaneously high pressure air from an engine driven pump 39 and a conduit 44 passes either through a conduit 126 and the servomotor chambers 124 and 126 or through a conduit 140 and the servomotor chambers 136 and 138 to a check valve 134 and an air relay valve 116 actuation of which moves a valve spool 146 to pass pressure air through conduits 152 and 36 to a transmission disconnect mechanism 38, which shifts the transmission 16 into neutral, and through a conduit 54 to an air-over-hydraulic brake cluster 56 which operates hydraulic brakes 12, 14. In operation, as the vehicle halts, the servomotor 88 or 96 is do-energized cutting the air flow to the relay valve and hence releasing the brakes 12, 14 and re-energizing the transmission automatically. The brakes are normally applied by supplying pressure air to the cluster 56 through conduits 50 and 54 from a pedal controlled air valve 46.
