STEER-DRIVE FOR VEHICLES

A steer-drive interposes respective left and right orbital gear drives (20, 22) into the vehicle drivetrain between the engine/transmission (10, 12) and the respective propulsion axles associated with each side of the vehicle. The orbital drive units comprise only an input gear (54) and an output gear (58) interconnected by at least one orbiting cluster gear (60, 61) that is supported in a rotating housing and also meshes only with the input and output gears. The orbital units are designed so that (a) when rotation of the housing (64) is prevented, driving torque is transferred at speed ratios selected to be as close to 1:1 as is practical, and (b) when steering torque causes rotation of the housing, the steering torque is added simultaneously in equal and opposite directions to the orbital units, causing the drive on one side of the vehicle to slow down at the same rate. The steer-drive is appropriate for the drivetrains of tracked vehicles, boats and airplanes.

Drive configuration for skid steered vehicles.

A drive configuration for a skid steered vehicle comprises a pair of electric motors (1a, 1b) for propulsion of the vehicle, one each coupled to drive a respective track (5a, 5b) on a respective side of the vehicle, and one or more electric steer motors (7a, 7b) coupled through a differential gear mechanism (6) to impose a speed difference between the tracks. An associated control system (20, 24, 25, 26) controls the current to each motor so that substantial contributions to the differential torque to turn the vehicle are made both by the steer motors and by the propulsion motors, in variable proportions preferably as a function of the vehicle speed.

The arrangement allows a simple steering control shaft (46) to receive steering control torque for normal turning and driving torque for propulsion drive-assisted pivot turning. A pivot turn brake (120), applied to the drive torque train, can make pivot turning precise.

Steer-drive for boats and planes

A steer-drive for vehicles primarily operated in fluids (e.g., boats and planes) interposes respective left and right orbital gear drives into the vehicle drivetrain between the engine/transmission or/speed-reducer and the vehicle's respective port and starboard propulsion elements. The orbital drive units comprise only an input gear and an output gear interconnected by at least one orbiting cluster gear that is supported in a rotating housing and also meshes only with the input and output gears. The orbital units are designed so that (a) when rotation of the housing is prevented, driving torque is transferred at speed ratios selected to be as close to 1:1 as is practical, and (b) when steering torque causes rotation of the housing, the steering torque is added or subtracted from the driving torque. Steering torque is applied simultaneously in equal and opposite directions to the orbital units, causing the vehicle's respective propulsion element on one side of the vehicle to speed up and ...

Said system comprises: an internal combustion engine (1); at least one steering drive (2); a differential gear assembly (3) comprising at least one drive element (4), at least one steering drive element (5) and two drive outputs (6) for driving the drive sprockets (7) of a drive shaft (8); a steering drive connection (9) between the steering drive (2) and a steering drive element (5); at least one additional drive element (10; 30) for transmitting the drive power of the internal combustion engine (1) to the drive element (4). The internal combustion engine (1) runs parallel with the drive shaft (8) and transmits the drive power directly or indirectly to the additional drive element (10; 30), which is mounted next to the internal combustion engine (1), when viewed in the driving direction.

Vehicle skid-steer control system

A control system for steering and travel of a skid-steer vehicle having right hand and left hand driving units, e.g. hydrostatic motors, has a pivoted speed input link 18 which includes two slotted cams 11, one for each of the drive units. A respective cam follower 23 engages in the slot 17 of each cam 11. The followers 23 are connected to speed control members 21 of the drive units. For steering, the follower 23 of one or both units is displaced along a slot 17 by a respective cam 25 for differential movement of control members 21. Each slot 17 is such that, with the speed signal set to zero, the movement of a follower 23 in the slot 17 causes no movement of pivot 19, and thus of either of the drive units. The operation of the steering control thus will not cause movement if the vehicle is stationary.

Drive configurations for skid steered vehicles

A controlled differential adapted to couple two shafts (7a, 7b) and steer input, such as those provided in a drive configuration for a skid steered vehicle, the controlled differential comprising: a pair of planet carriers (14a, 14b) arranged to turn with respective shafts; a pair of ring gears (12) interconnected by a cross-shaft such that the ring gears rotate in common; planet gears (11) and a pair of sun gears (10), the sun gears being coupled to at least one steer motor (9) to enable rotation of the sun gears in mutually opposite senses upon input from the steer motor.
