Abstract:
A bicycle (1000) includes a frame (1002), a suspension assembly (100) and a steering assembly (1018). The frame includes a head tube (1003) that rotatably receives a front fork assembly (1004). A steerer tube (1008) extends axially away from a fork crown (1010) of the front fork assembly. The suspension assembly includes an upper tubular support (102) longitudinally slidable relative to a lower tubular support (104). The upper and lower supports receive a first positive biasing means (138) and a first negative biasing means (140). The lower and upper supports are respectively connected to the steerer tube and a stem (1020) of the steering assembly such that the upper support slides longitudinally relative to the lower support adjacent the stem and above the fork crown.
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.
Abstract:
A vehicle height adjustment device includes a cylinder (230), a piston (131), a rod (150), a spring (500), an adjustor (250), a storage chamber (40), and a passage switch unit (300). The piston (131) divides a space inside the cylinder (230). The rod (150) has one end in the axial direction holding the piston (131) and has the other end supported at a vehicle wheel side. The spring (500) has one end in the axial direction supported at the body side and has the other end supported at the wheel side. The adjustor (250) includes an accommodation chamber (60) of fluid and supports the one end of the spring (500) to adjust a length of the spring (500) in accordance with an amount of the fluid in the accommodation chamber (60). The passage switch unit (300) closes an opening of the cylinder and includes first (R1) and second (R2) communication passages to switch a passage for the fluid in accordance with a movement of the piston (131).
Abstract:
The present application discloses a concealed rear wheel suspension device for a scooter, which comprisies a frame compoment, a suspension spring compoment and a back fork (10), the frame compoment includes a frame cover (1), a frame (2) and a stop (3) fixedly connected to the rear of the frame (2), a through hole is set on two sides of the rear of the frame; the suspension spring compoment comprises a link (6). A threaded end of the link (6) comprises sequentially across through the stop (3), a compression spring (7) and a washer (5), the threaded end is locked by a nut (4); two sets of holes are located on the front end of the back fork (10) along the vertical direction, wherein upper holes are rotatably connected to the through hole on the two sides of the frame (2) through bolts (12), and lower holes are connected to a hole end of the link through plugs (9).
Abstract:
A front wheel supporting structure for a straddle-type vehicle includes a front arm (10) which supports a front axle (6) and which extends rearward from a front axle to a location behind a front wheel (5), and a pair of upper and lower link members (21, 22) which is turnably connected to two vertically separated portions of a rear end of a front arm (10). The link members (21, 22) extend rearward. Rear ends (21b, 22b) of the link members are turnably connected to a vehicle body-configuring member. The front wheel supporting structure includes a front suspension mechanism (12) which suppresses turning motion of the front arm (10).
