Filed: 1959-11-25
Abstract: 897,021. Change-speed and clutch control. EATON MANUFACTURING CO. Nov. 25, 1959 [Feb. 20, 1959], No. 40108/59. Class 80 (2). Axial movement of the double-toothed clutch sleeve 27 selecting two ratios in a countershaft main or auxiliary change-speed gear for a motor vehicle is balked by stops 64, 72 for a predetermined time during which the sleeve 27 and one of the co-operating clutch members 4, 23 are synchronized by multiple-plate clutches 33, 39. The timing may be such that the balk is released ahead of, or actually at or after the instant of exact synchronization. As shown (Fig. 2) the input shaft 3 is clutched at 6 to the output shaft 12 for direct drive. For shift to reduce drive a compressed air servo 54 is pressurized, which moves right a rod 58, shift finger 60 and sleeve 27 until an abutment 111 on the finger 60 engages the stop 64 which prevents further rightward movement for a predetermined time and retains the sleeve 27 in an intermediate neutral position. In this position pressure is transmitted from the abutment 111 through the stop 64 and a member 61 to engage the synchronizing clutch 39, and a recess 83 (Fig. 7) in the finger 60 permits rightward (Fig. 4) movement of a spring-pressed ball 82 and plunger 91, the latter of which raises a valve plunger 97 which opens a valve 98 to connect a pneumatic timer valve 110 to a fluid-pressure source S. The inlet orifice of the valve 110 is pre-calibrated so that the valve chamber 109 is pressurized in a predetermined time after which a piston 106 and abutment 102 fast therewith move upward and the latter engages rods 66, 72 projecting from the stops 64, 71 to raise both stops, whereupon the sleeve 27 moves rapidly further right into synchronous engagement with the teeth 26 on the gear 23 to provide reduced drive. Shift from reduced to direct drive is made by pressurizing a servo 53 which moves the sleeve 27 left, the complete movement being balked for the predetermined time by the stop 71 during which the clutch members are synchronized by the clutch 33. The two synchronizing clutch presser members 61, 67 may be integral (Fig. 5, not shown) and the stops 64, 71 are pivoted thereto. A spring between pins 70, 70a on the stops bias the latter downwards. The timer valve may be operated by any other pressure fluid. Specifications 681,759 and 851,996 are referred to.
