Abstract: A bearing assembly having a metallic inner race, a metallic outer race, and a plurality of rollers positioned between the inner race and the outer race. A pad of non-metallic material is attached to the inner race and a bed of non-metallic material is attached to the outer race. A timing mechanism is mounted to the pad and the bed. Preferably the pad and bed are made of plastic and the inner race is embedded within the pad and the outer race is embedded within the bed.

Abstract: A hydraulic steering system (1) is described. The hydraulic steering system (1) comprises a steering motor (2) and a joystick (3) having a housing (4), a handle (5) mounted movably to the housing (4), a handle angle sensor (6) and return to center means (7) producing a restoring force on the handle (5).
Such a system should help an operator to steer a vehicle in a safe manner.
To this and the return to center means (7) comprises an input (8) for a parameter of a vehicle to be steered and produces a variable restoring force depending on a signal at the input and/or of an angle of the handle (5).-

Abstract: According to the present disclosure, a system for providing steering control in a dual path machine includes a propulsion controller operatively connected to plants of the machine for driving ground contacting elements, the propulsion controller being configured to control steering of the dual path machine through drive signals sent to the plants, and a brake controller operatively connected to left and right brakes of the machine, the brake controller being configured to control steering of the machine by providing differential brake pressures to the left and right brakes. The system of the present disclosure provides redundant steering control by receiving an input signal at the brake controller with an indication of steering position, receiving an input signal at the brake controller with an indication of brake position, and providing a differential brake pressure to brakes of the dual path machine based on the steering input signal and brake input signal.

Abstract: A system (30), apparatus and method are provided for limiting operating speed at high temperatures of a self-propelled, agricultural product applicator (10) having a hydraulic drive system (28) including a pump (32) supplying pressurized hydraulic fluid to a variable-displacement hydraulic motor (12, 14, 16, 18) operatively connected for propelling the applicator (10). A temperature sensor (38) detects a temperature of the pressurized hydraulic fluid in the hydraulic system (28). A propel controller (40) is operatively connected between the temperature sensor (38) and the propulsion motor (12, 14, 16, 18) and configured for limiting displacement of the propulsion motor (12, 14, 16, 18) according to one or more predetermined de-rated conditions resulting in reduced motor speed, in accordance with a predetermined schedule, when predetermined motor de-rating activation temperature limits of the hydraulic fluid are detected by the temperature sensor (38). The controller (40) is further configured for providing a de-rated condition warning signal to limiting displacement of the propulsion motor (12, 14, 16, 18).
