The control arrangement includes a brake valve 39 with inlet and exhaust ports 42, 50 and outlet supply ports 41, 43 respectively connected to a clutch selector valve 54 and to the brake 22. The valve 39 is controlled by a hand lever 45 normally held disengaged by a spring 53 and carrying roller bearing members 44, 51 engageable with valve plungers 40a, 52. When handle 45 is thus held brake ports 43, 50 are vented to exhaust and ports 41, 42 are connected to admit pressure fluid to the selector valve 54 through port 41. Initial movement of lever 45 to the left engages members 40a, 44 to move a valve spool 40 to the left against a weak spring 47 to cut off the clutch supply port 41 and open the brake supply port 43, further movement of the lever compressing a second stronger spring 46 to permit engagement of members 51, 52 to operate a relief valve 49 through a spring 48 to regulate the brake supply pressure. The clutch selector valve 54 is operated by a second hand lever 63 operating a spool element 55 controlling the admission of pressure fluid to the forward or reverse drive clutch through port 56 or 57. The system is particularly applicable to the forward and reverse drive of a track of a crawler tractor, the brake being operable to brake the vehicle irrespective of the direction of travel, while the control valves permit disengagement of both the forward and reverse drive clutches when the brake is engaged. The jointly controllable clutch - brake system and the control valves form the subject matter of divisional Specifications 1,145,127 and 1,145,128 respectively.

Abstract: 1467458 Change-speed control ZAHNRADFABRIK FRIEDRICHSHAFEN AG 4 Dec 1974 [5 Dec 1973] 52424/74 Heading F2D In a transmission for vehicles providing a plurality of forward ratios and reverse, with hydraulically operated ratio - establishing clutches and brakes, a ratio-selector valve, and valves for controlling the rate of pressure buildup in selected clutches and brakes, the pressure build-up in one of the clutches, which is engaged for more than one ratio, is controlled by a valve having means to vary the rate of pressure buildup in accordance with the selected ratio. In a transmission and control means therefor similar to the disclosure in Specification 1,274,490, three forward ratios and reverse are established by selective engagement of various combinations of clutches K1, K2 and brakes B1, B1F, B2, the clutch K2 being engaged for both the high forward ratio and reverse. For high forward ratio pressure fluid is directed by a system of valves (not shown) including the selector valve, shift valves, &c., to the brake B1F and clutches K1, K2, and the rate of pressure build-up in K2 is controlled by the valve 110. Pressure fluid arriving in a conduit 215 passes through a pipe 126 to the clutch, but the flow is restricted by rightward movement of the valve member 111 as pressure fluid passes through a restriction 126a. The valve member is ultimately returned to its leftmost position as pressure builds-up in a chamber 124, to which it has access through a one-way throttle 125A, to move a piston 121 against a spring 122. When reverse ratio is selected pressure fluid is directed to conduits 118 and 215, the pressure 118 being transmitted through valves 212a, 130 to the brake B2 and through a passage 243 to the left-hand side of a piston 140 whereby that piston is ineffective to delay pressure build-up, and B2 is engaged without delay. The pressure in 118 has access also to a chamber 117 of the valve 110 where its effect is to increase the rate of pressure build-up in the clutch K2.

[Also in Division H1] To rotate a switch shaft 27 anticlockwise from one switching position to the next, an electric motor (10, Fig. 1) is rotated clockwise to cause clockwise rotation of a shaft 15 via gearing (11, 12, 13, Fig. 1) and a unidirectional freewheeling clutch (14, Fig. 1). Shaft 15 carries a crank 16 having a pin 17 passing through a block 18 on a rod 19 sliding in a sleeve 22 pivotable about a stationary pin 23. A compression spring 20 on rod 19 bears on sleeve 22 and pin 17 through washers. Pin 17 carries a roller 24 that can engage any one of a plurality of radial notches 25 on a rotary disc 26 keyed to shaft 27. A pawl 28 engaging a ratchet-wheel 29 on shaft 27 and pivotable about a fixed pin 30 carries a roller 32 co-operating with a cam 33 keyed to shaft 15 so as to lock shaft 27 in different switching positions. The clockwise rotation of shaft 15 causes crank 16 to rotate from a downward position to the dead-centre position, Fig. 3; cam 33 then causes pawl 28 to unlock disc 26 and roller 24 enters a notch 25 and drives disc 26 through 60 degrees. It then leaves the notch (Fig. 4), crank 16 rotates to its downward position, and pawl 28 locks disc 26. When disc 26 is driven, the gear (13) and the motor (10) are disengaged from shaft 15 by the clutch (14); disc 26 is driven by energy stored during compression of spring 20, some energy being available for the next drive. During clockwise rotation of the motor (10), a similar shaft 15<SP>1</SP> remains stationary. If the motor (10) is rotated anticlockwise, shaft 15 remains stationary, and shaft 15<SP>1</SP> drives shaft 27 clockwise through 60 degrees as before.
