Abstract:
An integrated and self-contained suspension assembly having a gas spring integrated with a shock absorber (damper) is described. The rigid gas cylinder of the air spring is divided into a first gas chamber and a second gas chamber. A flow port connects the first and second gas chambers, and can be manually opened or closed by valve and a simple one-quarter turn rotation of an external knob to instantly switch the gas spring between two different spring rates. The different spring rates are functions of the separate or combined volumes of the two gas chambers. The integrated suspension assembly is compactly packaged and self-contained, i.e., does not require any externalities, such as gas sources or electricity, to operate.
Abstract:
A straddled vehicle includes a seat 17 arranged over an opening 36 of a storage box 31 and a hinge 32 for attachment of the seat 17 to a frame 2. The hinge 32 includes a movable bracket 64 rotatable together with the seat 17 with respect to the frame 2 between a closed position and an open position and configured to overlap the opening 36 of the storage box 31 in a vehicle plan view when the seat 17 is arranged in the closed position. The straddled vehicle further includes a box seal 45 configured to tightly seal the clearance gap between the seat 17 and the storage box 31 and a bracket seal 81 configured to tightly seal the clearance gap between the seat 17 and the movable bracket 64.
Abstract:
A bicycle rear wheel suspension systems. In one aspect, a bicycle rear wheel suspension system is provided comprising a bicycle rear wheel suspension system comprising a frame comprising a bottom bracket and a first chain stay, the system further comprising a rear wheel comprising an axle, and a first linkage member pivotally connected with respect to the first chain stay at a first main pivot point, the first linkage member extending rearwardly to bridge the main pivot point and the axle, wherein the main pivot point is in a position higher than the bottom bracket, and closer to the axle than it is to the bottom bracket, and wherein at least the first linkage member further comprises a pivotable connection point for a shock absorbing mechanism bridging this connection point and a portion of a remainder of the frame. Further, a bicycle comprising the rear wheel suspension system is provided.
Abstract:
A reaction force adjustment support device includes: a pressure data storage unit (102) storing pressure data of respective spring chambers; a graphic user interface unit (108) displaying a display screen; a reaction force calculator (109) calculating reaction force data by using the pressure data of the respective spring chambers stored in the pressure data storage unit (102); a graph generating unit (110) generating a graph of reaction force characteristics by using the reaction force data calculated by the reaction force calculator (109); and a controller (111) displaying a screen for adjusting a reaction force where the screen has an operation portion for adjusting spring pressures provided for the respective spring chambers and a drawing area of the graph on the display screen, and controlling the reaction force calculator (109) and the graph generating unit (110) by user's operation with respect to the operation portion with the pressure data changed for the respective spring chambers to vary the graph.
Abstract:
A flow path control device according to one embodiment includes a first valve (301), a unit main body (330) and a control valve (305). The unit main body (330) has an accommodation portion (342a), a first radial communication hole (349a) and a side recess portion (342b). The accommodation portion (342a) is recessed from a chamber (B1) accommodating the oil to cause the control valve (305) to close the first radial communication hole (349a). The side recess portion (342b) is recessed from the chamber (B1) so as to be continuous to the accommodation portion (342a) and not to be continuous to the first radial communication hole (349a). The control valve (305) is movable in the accommodation portion (342a) of the unit main body (330) between a position at which a groove (305a) of the control valve (305) communicates with the side recess portion (342b) and the first radial communication hole (349a) and a position at which the groove (305a) does not communicate with them.
Abstract:
A vehicle height adjustment apparatus according to one embodiment include a spring (500), a spring-length changing unit (250), a first valve (301), a control valve (305) and a second valve (302). The spring-length changing unit (250) changes a length of the spring (500) in accordance with an amount of oil in a jack chamber (60) that accommodates the oil. The first valve (301) opens and closes a first communication path in which the oil supplied from a pump (600) is oriented toward a reservoir chamber (40) that stores the oil. The control valve (305) opens and closes a discharge flow path oriented toward the reservoir chamber (40) from a chamber (B1) that accommodates the oil to close the first valve (301). The second valve (302) opens and closes a second communication path in which the oil supplied from the pump (600) is oriented toward the jack chamber (60) when the first valve (301) is closed.
