20120152671 | HYDRAULIC SHOCK ABSORBER - In a hydraulic shock absorber | 06-21-2012 |
20120247890 | HYDRAULIC SHOCK ABSORBER - In a hydraulic shock absorber, a damping force generating device provided between a piston side oil chamber of a cylinder and a rod side oil chamber is provided with a through-hole which communicates the piston side oil chamber of the cylinder with the rod side oil chamber of the cylinder via an outer flow path of the cylinder. A leading end portion of a piston rod is provided with a needle which can come in and out of the through-hole of the damping force generating device, and an opening degree of the through-hole can be varied by the needle according to a forward and backward position of the piston rod with respect to the oil chamber of the cylinder. | 10-04-2012 |
20130081912 | HYDRAULIC SHOCK ABSORBER - In a hydraulic shock absorber | 04-04-2013 |
20130105259 | HYDRAULIC SHOCK ABSORBER | 05-02-2013 |
20130285300 | HYDRAULIC SHOCK ABSORBER - An object of the present invention is to ensure that, during adjustment of a spring load by an adjuster, total fully-stretched lengths of an outer tube and an inner tube remain unchanged and the adjuster is prevented from protruding from an upper surface of a cap. In a hydraulic shock absorber | 10-31-2013 |
20140001716 | VEHICLE HEIGHT ADJUSTMENT DEVICE IN VEHICLE | 01-02-2014 |
20140077464 | MOTORCYCLE - An object of the present invention is to control according to a vehicle height an auxiliary device provided in a vehicle. A motorcycle | 03-20-2014 |
20140077465 | VEHICLE HEIGHT CONTROL DEVICE FOR MOTORCYCLE - An object of the present invention is to provide a vehicle height control device for a motorcycle which enables a vehicle height to be retained at any intermediate position and which implements instantaneously switchover of the vehicle height. A vehicle height control device for a motorcycle has vehicle height detection means for detecting the vehicle height, a selector valve that connects, by switching, a jack chamber in a hydraulic jack to an oil reservoir chamber that communicates with oil chambers in a damper tube, and control means for controlling the switching of the selector valve based on a detection result from the vehicle height detection means in order to retain the vehicle height at any position. | 03-20-2014 |
20140077466 | MOTORCYCLE - An object of the present invention is to stabilize a rider's driving position in spite of a change in vehicle height. Provided is a motorcycle | 03-20-2014 |
20140083093 | VEHICLE HEIGHT ADJUSTING DEVICE FOR MOTORCYCLE - An object of the present invention is to reduce current consumption for switching and holding an actuation position of an electromagnetic change-over valve included in a vehicle height adjusting device for a motorcycle and to surely hold the actuation position. In a rear-wheel side vehicle height adjusting device for a motorcycle, after applying a startup current to a solenoid of a change-over valve in order switch an actuation position of the change-over valve, while switching an applied current to the solenoid to a holding current which is smaller than the startup current and holding the actuation position of the change-over valve, a control section intermittently applies a large current, which is larger than the holding current, to the solenoid. | 03-27-2014 |
20140084528 | VEHICLE-HEIGHT ADJUSTMENT APPARATUS OF MOTORCYCLE - In a vehicle-height adjustment apparatus of a motorcycle having a hydraulic jack and a hydraulic pump attached to a hydraulic shock absorber, a structure is provided in which an oil return path of a hydraulic jack and a suction port of a hydraulic pump are not required to be opened in a sliding surface of a piston in a damper tube. In the vehicle-height adjustment apparatus of a motorcycle, an oil return path is opened in an outer flow path of the damper tube to cause the oil of a jack chamber to return to the oil chamber of the damper tube when a plunger of the hydraulic jack reaches a protruding end in the jack chamber. | 03-27-2014 |
20140084554 | VEHICLE HEIGHT ADJUSTING DEVICE FOR MOTORCYCLE - In a vehicle height adjusting device for a motorcycle, the vehicle height is adjusted on the basis of proper vehicle speed information when a failure occurs in a vehicle speed sensor. In the vehicle height adjusting device for a motorcycle, when a failure occurs in a vehicle speed sensor, a control section adjusts vehicle height by using vehicle speed information calculated from an engine speed signal, a shift position signal of a transmission, and an ON/OFF signal of a clutch. | 03-27-2014 |
20140084555 | VEHICLE-HEIGHT ADJUSTMENT APPARATUS OF MOTORCYCLE - In a vehicle-height adjustment apparatus of a motorcycle having the hydraulic jack attached to the damper, damping force characteristics of a damper are stabilized, the influence of the charged gas pressure of an oil reservoir chamber is eliminated, and the sealing performance of a hydraulic jack is reduced. In the vehicle-height adjustment apparatus of a motorcycle, a back pressure chamber is provided on a side opposite to a jack chamber, with a plunger being interposed therebetween inside a hydraulic jack, and this back pressure chamber is communicated with a hydraulic chamber inside a damper tube. | 03-27-2014 |
