20090079146 | AXLE AIR DUMP FOR MULTIPLE AXLE VEHICLES - A system and process for controlling vehicle loading on a multi-axle vehicle and improving maneuverability is disclosed. The system includes a reservoir of pressurized air and associated leveling valve that uses a relay valve to improve refill times when the vehicle returns from a dump mode operation to normal operation. The process reduces pressure in one or more of the axles when maneuvering the vehicle at predetermined slow speeds and maintaining that first predetermined pressure while the other axle(s) is at a greater pressure than the first axle. By preventing complete exhaustion of pressure from the suspension system, restoring air pressure is attained more quickly. Also, use of a relay valve enables higher flow rates to improve the refill time of the pneumatic suspension system after the dump operation. | 03-26-2009 |
20090115149 | DYNAMIC BALANCING PERSONAL VEHICLE - A seating system to be easily attached to an existing dynamic balancing personal vehicle is provided. The seating system allows both seated and standing use of the dynamic balancing personal vehicle, and provides for activation of rider present sensors contained in the foot platform of the dynamic balancing personal vehicle by the weight of the rider on the seating system. The seating system also provides for secure transfer of rider forces into the attached dynamic balancing personal vehicle, as well as shock attenuation, rider height adjustment, and rider center of gravity trimming. Alternatively, a dynamic balancing transportation system incorporating a flexible seating system for a rider is provided. | 05-07-2009 |
20090212512 | Method and device for increasing the driving stability of motor vehicles - The invention relates to a method and device for increasing the driving stability of motor vehicles (PB), comprising a hydraulically-operated device support (GT) for mounting a working device (FS). According to the invention, the device support (GT) is controlled at a given set position, whereby an actuating parameter for the positional control (PR) is given in the form of a hydraulic pressure set value and a hydraulic pressure is regulated to the given hydraulic pressure set value, whereby a stabilizing time for the pressure regulation is much smaller than a stabilizing time for the positional regulation. Said device comprises a position regulator (PR) for positional regulation of the device support (GT), whereby an actuating parameter of the position regulator (PR) is given in the form of a hydraulic pressure set value and a pressure regulator (RE) is coupled to the position regulator (PR) to regulate the hydraulic pressure to the given hydraulic pressure set value. The above is of application, for example, in snow piste-bashing machines. | 08-27-2009 |
