Abstract: 727,829. Motor vehicle driving and steering gear. GATES, G. R. G. Aug. 25, 1953 [Dec. 19, 1952], No. 32295/52. Addition to 722,897. Class 79(2). A clutch operated vehicle driving and steering gear system, arranged to drive a pair of road wheels differentially to cause turning of the vehicle, comprises driving means, two main clutches connecting the road wheels to the driving means, a differential gear having first, second and third elements, the first and second elements being connected to the road wheels and the third element being connected to a steering clutch which can be connected to the driving means or to an arresting device. As shown in Fig. 1, the arrangement is similar to that shown in Fig. 1 of the parent Specification an input shaft 10 being connected through a reversing gear 11 ... 15 to a countershaft 16 which is gear connected to gears 18, 20, which can be alternatively clutched to a shaft 21. To the shaft 21 can be alternatively clutched gears 26, 29 meshing with gears 27, 30 on a shaft 28, the shaft 28 being connected through the normally engaged main clutches 35, 36, gears 37 ... 40 and shafts 41, 42 to track sprockets 43, 44 forming the road wheels. Gears 45, 46 of smaller diameter than the gears 37, 38 mesh with the gears 39, 40 and are shaft-connected to the first and second elements 49, 50 of the differential gear 51, the third element or carrier 52 being connectable through the normally disengaged steering clutch 54 and a gear 56 to the gear 29. Steering is effected by releasing one of the main clutches and engaging the steering clutch. The arresting device 60 conprises a contracting brake band 60c engageable with a rim 60b secured to the carrier 52 of the differential gear. Disengagement of one of the main clutches 35, 36, and operation of the brake enables the sprockets 43, 44 to be driven in opposite directions to achieve a pivot turn of the vehicle. A very close turn (as distinct from a pure pivot turn) can be obtained by partially releasing the brake. According to the Provisional Specification the steering clutch is formed with a brake, the clutch and brake being controlled hydraulically and a control valve being provided to feed pressure liquid to either the clutch or brake. The valve may be under the control of a separate controller or may be interconnected with the gear lever, being operative when the bottom gear is engaged. In another embodiment, Fig. 4, the arresting device 60 is omitted and the shaft 21 carries freely a gear 64 permanently in mesh with the gear 56. By means of a member 72 engaging a groove 71 in a boss 70 on the gear 64, the gear 64 can be selectively meshed with the gear 30 or with teeth 69 in a bore 68 in a fixed housing 65, the latter position causing a pivot turn of the vehicle. Specifications 563,339 and 722,709 also are referred to.
