Patent ES-347186-A1 (ES)
Title: Control of pneumatic cyclic gear boxes
IPC: F16H59/04
Filed: 1967-11-15
Abstract: In a vehicle gear change mechanism in which a hand lever actuates a series of fluid pressure ratio shift control valves a fluid pressure operated member is arranged, upon an establishing movement of the lever, to hold the latter in the gear-engaged position and also, if the pressure in the system falls to a predetermined minimum value, to automatically return the lever to the neutral position. In the system shown air from an engine-driven pump 80 is supplied to a reservoir 83 from which it passes by a line 84 to the shift control valves 55 connected by lines 87 to the gear-box 88, and by a line 89 to a door actuator 90. A second line 85 from the reservoir 83 includes a low pressure protection valve 86 and leads to inlets 44, 45 of valves 37, 38 controlling the lever locking mechanism. The hand lever 13 which is movable along a central gate slot 14 in a cover 12 for gear selection and rotatable about a pivot 18 for establishment has a depending Y-shaped arm 70 for operating the shift control valves 55. In addition it has arms 24 engaging pins 25 on a cross-shaft 22 housing plungers 28, 30, the ends of which, in the neutral setting shown, are spaced from the valves 37, 38 so that the air pressure at inlets 44, 45 is communicated through valve bores 51, 52 to the opposite ends of cross-shaft 22 to balance the latter and hold the lever 13 in position. When the lever is moved to a gear-engaging position, the arm 70 operates the appropriate shift valve 55 and at the same time the plunger 28 or 30 located above the operated shift valve moves against the end of valve 37 or 38 to close the bore 51 or 52 and open the valve to exhaust port 46 or 47, so that the differential air loading then acting on cross-shaft 22 is transmitted by pins 25 to lever 13 which holds the shift valve fully open and is itself held in the gear-engaged position. In the event of the air supply pressure falling to the minimum value, the valve 86 opens to vent line 85 to atmosphere so that the pressure supply to inlets 44, 45 is cut off, whereby loading springs 31, 32 on plungers 28, 30 act to centre cross-shaft 22 and thus automatically return hand lever 13 to the neutral position. In this condition gear may still be engaged by appropriate setting of the lever 13 and holding it in position by hand. To engage reverse gear it is necessary to withdraw a retractable stop (91), Fig. 3 (not shown), by a knob (95) to allow full engaging movement of the valve operating arm 70, the stop being returned automatically by a spring (92) when reverse gear is disengaged. For door operation the hand lever 13 is raised against the action of a spring 101 until the lower end of a sleeve 96 clears a raised baulk lug (95) on the edge of the end gate slot D, Fig. 1 (not shown), before being fully engaged in the slot to operate the appropriate valve 55.
