Abstract
744,706. Controlling clutches. ROVER CO., Ltd. Aug. 3, 1954 [Sept. 14, 1953], No. 25324/53. Class 80(2) A normally-open switch 12, Fig. 1, is automatically closed during a gear change on a motor vehicle to complete a circuit through a solenoid 10 operating the valve of a fluid-pressure servomotor to disengage a clutch interposed either between the engine and the gearbox or between the gearbox and the road wheels, and a normally-open switch 14 is automatically closed if the speed of the clutch driving member falls, while the clutch is disengaged, below the speed of the clutch driven member to complete a circuit, ioncluding the switch 12, through a solenoid 13 to open the engine throttle. either directly or through a servomotor, independently of the throttle pedal. The switch 12 may be operated by a movable knob on a manual gear lever, but the gear may be operated automatically in accordance with engine speed or load. The switch 14 may be operated by a differential gear connected across the clutch, by a member having limited angular movement relative to one clutch member and in frictional engagement with the other member, by the pressure differential between two pumps, or by a single pump which generates pressure only when there is a difference of speed between the clutch driving and driven members. A further switch, which is opened only when a gear is engaged, may be arranged in series with the switch 12, so that the clutch will re-engage as soon as a gear has been engaged even if the gear lever knob is not released. Fig. 3 shows such an arrangement for a four-speed gear in which the gear lever is moved in one direction for first and third gears and in the opposite direction for second and fourth gears, the switch 12 being replaced by a normally-open two-way switch 15 while normally-closed switches 18 and 19 are opened automatically by engagement of first or third gears and second or fourth gears respectively. In Fig. 3, also, the clutch is engaged by energization of a winding 21 through a normally-closed relay switch 22 which is opened by the solenoid 10 when the latter is energized. Specification 715,746 is referred to.
