Abstract
379,973. Variable-speed gearing. ALVIS CAR & ENGINEERING CO., Ltd., and CLARKE, G. T. SMITH-, Alvis Works, Holyhead Road, Coventry, Warwickshire. Jan. 30, 1932, No. 2825. [Class 80 (ii).] Variable-speed gearing suitable for vehicles comprises a fluid coupling the driving-member 4 of which is directly connected to a sun pinion 15 while the driven member 7 of the coupling is connected through a friction clutch 11 to an annulus 12, the driven shaft 18 of the gearing carrying planet pinions 16 meshing with the sun 15 and with the annulus 12. When the clutch 11 is disengaged, the driven coupling member 7 is perfectly free and no power is lost although an engine shaft 2 is still rotating, the drive being disconnected. An extension 14 of the shaft 2 carries the pinion 15. The clutch 11 is held in by a presser plate 10 adapted to be withdrawn to free the clutch when a collar 27 is slid to the right. An arrangement is described by which a pedal acts on the collar 27 to open the clutch and subsequently to apply a brake band 29 on a drum 28 connected by a sleeve 26 to the annulus 12, so as to effect a definite wholly mechanical reduced drive useful in starting a vehicle. With the friction clutch engaged, the hydraulic coupling is operative to effect a drive which varies automatically with the load. The gearing may be arranged between the engine and conventional change gearing, in which case means are provided to arrest the shaft 18 to facilitate operation of the change gearing.
