| 20150014086 | DUAL STEERING SYSTEM FOR A VEHICLE - The present invention discloses a dual steering system including a first front wheel and a second front wheel, a lateral steering linkage connecting the first and second front wheels, a first steering system with a first steering wheel and a power steering module that assists steering inputs applied to the first steering wheel, and a second steering system with a second steering wheel and a torque sensor in communication with the power steering module of the first steering system and monitoring steering inputs applied to the second steering wheel, whereby the power steering module may provide power assist to the steering inputs applied to the second steering wheel. | 01-15-2015 |
| 20150291206 | CLUTCH DEVICE AND STEERING DEVICE - A clutch apparatus is configured such that a first mode, a second mode and a third can be switched among these three modes. In the first mode, the rotating force is not transmitted between the steering-wheel-side housing and the tire-side housing. In the second mode, the steering-wheel-side housing and the tire-side housing are being mutually locked in place and, in this locked state, the rotating force can be transmitted to for the rotation in the both directions. In the third mode, the transmission of the rotating force can be canceled such that while the rotating force can be transmitted, between the steering-wheel-side housing and the tire-side housing, relative to the rotation in one direction, the rotation of either the steering-wheel-side housing or the tire-side housing in the other direction is allowed. | 10-15-2015 |

| 20100059306 | STEERING MECHANISM COMPRISING A PRESSURE RELIEF VALVE FOR DAMPING THE END POSITION AND PROTECTING THE PUMP FROM BEING OVERLOADED - The invention relates to a steering device for vehicles with a double-acting hydraulic working cylinder, which is divided into two working chambers by a piston, which is displaceably mounted in the working cylinder, to pivot at least one vehicle wheel, and a pressurizing means device producing a volume flow of a hydraulic medium, the hydraulic medium being supplied to a rotary slide valve, which supplies the volume flow, depending on the rotary slide valve position, to the working chambers of the double-acting hydraulic working cylinder or to a reservoir for the hydraulic medium, wherein when a certain pressure is exceeded in the feed line to the rotary slide valve, a pressure relief valve guides at least a part of the total volume flow of the hydraulic medium past the rotary slide valve in particular to the reservoir. | 03-11-2010 |
| 20130146386 | EMERGENCY STEERING SYSTEM OF CONSTRUCTION EQUIPMENT - The present disclosure relates to construction machinery such as an excavator or a wheel loader, and more particularly, to an emergency steering apparatus for construction machinery, capable of controlling a steering operation at the time of emergency in which a part of equipment malfunctions or is in an inoperable state. More specifically, an emergency steering apparatus for construction machinery according to an exemplary embodiment of the present disclosure includes: a steering actuator; an emergency hydraulic pump connected to the steering actuator through a pair of driving flow paths; an emergency steering unit configured to receive working oil, which is discharged from the emergency hydraulic pump, and operate a steering means; and an emergency steering controller configured to control whether or not the emergency hydraulic pump is operated. | 06-13-2013 |
| 20150021116 | Steering Arrangement - A steering arrangement including a first, second, third and fourth hydraulic chamber, the first and third chambers being operable to steer in a first direction and the second and fourth chambers being operable to steer in a second direction. A pump system supplies fluid to a steering system, which is operable to supply the pressurised fluid to one or more of the first, second, third and fourth hydraulic chambers. The steering system having a first mode wherein fluid is supplied to the first and third hydraulic chambers to steer in the first direction, or pressurised fluid is supplied to the second and fourth hydraulic chambers to steer in the second direction. The steering system having a second mode to steer in the first direction, or to steer in the second direction, such that the steering ratio is higher in the second mode than in the first mode. | 01-22-2015 |
| 20160031475 | AUTOMOBILE ACTIVE STEERING SYSTEM WITH CYCLOIDAL-PIN WHEEL MECHANISM - The invention discloses an automobile active steering system with a cycloidal-pin wheel mechanism, and aims at overcoming the contraction between light steering effort and flexibility. The automobile active steering system comprises a steering hand wheel ( | 02-04-2016 |
| 180407000 | With electrical backup | 2 |
| 20150107934 | POWER SUPPLY CURRENT MONITORING DEVICE - A power supply current monitoring device is used for a load drive apparatus with two systems to drive a load. Each system includes a drive circuit connected in parallel with a battery, a capacitor connected between the battery and the drive circuit, and a relay connected between the drive circuit and a point at which power of the battery is divided between the systems. When overcurrent is detected once in one system, a repetitive monitoring process is performed. The monitoring process finally determines that the overcurrent actually occurs when a predetermined condition is satisfied after repeating a monitoring cycle in which an overcurrent time during which the overcurrent continues after the relay is turned ON is accumulated. The condition is satisfied when the monitoring cycle in which the overcurrent time reaches a predetermined threshold is repeated a predetermined consecutive number of times. | 04-23-2015 |
| 20150298722 | DEVICE FOR ASSISTING OR AUTOMATIC GUIDING OF A MOTOR VEHICLE - A device for assisting or automatic guiding of a motor vehicle, having a first steering actuator with an allocated steering control unit, a gear rack, a steering column and a steering handle, wherein the steering column and the steering actuator have effect on the common gear rack, wherein there is at least one second steering actuator having an additional allocated steering control unit, wherein the second steering actuator has effect on the common gear rack. | 10-22-2015 |
