Title: Driving and steering mechanism for vehicles, especially of the endless track type
IPC: B62D11/10
Filed: 1945-04-04
Abstract: 598,189. Motor-vehicle driving-gear. AKTIEBOLAGET INDUSTRIKOMPANIET. April 4, 1945, No. 8341. Convention date, March 14, 1944. [Class 79 (ii)] A driving and steering mechanism for vehicles, particularly endless track vehicles, in which each track is driven by a half-shaft through a planetary gearing, is characterised by an additional transmission device which superposes motion on one or other or both half-shafts or their planetary gears through a continuously variable mechanical or hydraulic gear. The continuously variable gear may be provided with a reverse gear, and couplings may be arranged to connect or disconnect the superimposed drive with the planetary gear carriers of each half-shaft. As shown the shaft 1 drives through gearing 2, 3, 5, 6 the shaft 7, 8. Fixed to the shaft 7 is a sun gear 9, and the sun gear 11 is fixed to the half-shaft 15 which drives the rear side road wheel or endless track. The two planet pinions are freely mounted on a cross shaft whose ends are fixed in the casing 13 which is provided with a brake 16 and is geared to a pinion 33. The casing 13 can be clutched to the half-shaft 15 by a clutch 14, and the pinion 33 may be clutched to its shaft 30 by a clutch 34. The two clutches 14, 34 may be interconnected as shown by a link 35 for alternative operation, or they may be operated simultaneously or independently. Power is also taken from the shaft 1 through a continuously variable gear 25, which may be provided with a clutch and a reversing arrangement, and gearing 27, 28, 29 to rotate the two shafts 30, 31 in opposite directions. During normal running, the brakes 16, 23 are kept applied and clutches 14, 34, 37, 39 disengaged, but by releasing one brake, e.g., 16, and engaging the corresponding clutch on the auxiliary drive, e.g., 34, a variable additional drive can be superimposed on the casing 13 to speed up the half-shaft 15 and so turn the vehicle. If desired, the vehicle may be turned more sharply by releasing both brakes 16, 23 and superimposing a drive on both casings 13, 21 in opposite directions by engaging clutches 34, 39 and disengaging clutches 14, 37. Alternatively, the shaft 26 may be driven from a separate source of power, or it may be manually manipulated.

[Also in Division E2] In a fluid pressure safety brake system the brake actuator 30 is of the type disclosed in Specification 955,062. The fluid pressure system also includes two reservoirs 10, 12 and a parking reservoir 24. A control valve 26 normally supplies pressurized fluid from reservoir 24 through conduit 32 and 138 to deactivate the locking means and through a continuation of conduit 32 to a further control valve 106. The fluid acts on the spring- loaded enlarged head 124 of a plunger 122 of the control valve 106 to raise the plunger in its housing bore 120 out of engagement with a spring-loaded valve member 130. With valve member 130 seated an outlet port 110 of the control valve 106, which is connected to the emergency portion 40 of the actuator 30, is vented to the atmosphere through a passage 134 in plunger 122. An inlet port 114 of the control valve 106 is connected at all times to the parking reservoir 24. The brakes are normally actuated by a conventional brake valve 36. The emergency or parking application of the brake is actuated by moving handle 102 of control valve 26 whence conduit 32 is vented to the atmosphere through exhaust opening 104 to activate the locking means and cause plunger 122 of the control valve 106 to unseat valve element 130 to bring the parking reservoir into communication with the emergency portion 40 of the actuator. The control valve 26 is of the combined manual and automatic type and preferably constructed as in Specifications 944,821, 944,822 and 944,823 such that should the fluid pressure in the parking reservoir drop to a predetermined low value, e.g. 40 p.s.i., the control valve 26 automatically vents conduit 32.
