The hydraulic control assembly includes a fluid pump, a fluid responder and a fluid path. The fluid pump is mountable to a bicycle handlebar. The fluid responder is mountable to the bicycle suspension. The fluid path links the fluid pump and the fluid responder. The fluid responder is operatively connected to the bicycle suspension to operate the bicycle suspension between first and second suspension settings in response to fluid displacement between the fluid pump and the fluid responder.Type: ApplicationFiled: September 5, 2008Publication date: March 11, 2010Applicant: SRAM CorporationInventor: Matthew Morris

Publication number: 20100025957Abstract: A bicycle suspension system is provided with a first tubular element, a piston, a piston rod, a first sealing member and a switching valve. The piston is coupled to the piston rod, and is slidably disposed in the first tubular element. The first sealing member is disposed in the first tubular element adjacent such that a first air chamber is formed between the piston and the first sealing member. The switching valve is coupled to the first sealing member. The switching valve opens a communication passageway between the first air chamber and a second air chamber to connect the first and second air chambers when in the opened position, and closes the communication passageway between the first air chamber and the second air chamber to separate the first and second air chambers when in the closed position.Type: ApplicationFiled: July 31, 2008Publication date: February 4, 2010Applicant: SHIMANO INC.Inventor: Jun INOUE

Patent number: 7637341Abstract: An apparatus capable of temporarily limiting travel of the rear suspension system of a motorcycle for the purpose of obtaining better traction when accelerating. The apparatus includes a device having a first base secured to at least one frame member of the motorcycle at a location above a rear suspension member of the motorcycle, and a second base secured to the rear suspension member at a location in proximity to the first base. A post is pivotally mounted to the first base to have first and second positions. In the first position, the post extends toward the second base an engages a retention feature in the second base to prevent movement of the rear suspension member and frame member toward each other. In the second position, the post is disengaged from the retention feature and pivoted away from the second base to permit movement of the rear suspension member and frame member toward each other.Type: GrantFiled: February 12, 2007Date of Patent: December 29, 2009Inventor: Edward Daniel Schnick

Publication number: 20090267317Abstract: A shock absorbing frame for a bicycle includes a seat tube extending along a lengthwise axis, a front frame unit, a rear frame unit, and a shock-absorbing member. The front frame unit includes top and bottom tubes extending rearwardly to terminate at upper and bottom ends, respectively. A connecting member is disposed between the top and down tubes, and extends from one of the top and down tubes. The rear frame unit includes a rear-axle stay and a chain stay. The rear-axle stay extends forwardly to bypass the lengthwise axis, and has a first front mount end. The chain stay has a second front mount end. A bottom bracket is disposed to interconnect the bottom end and the second front mount end. The shock-absorbing member is disposed between the first front mount end and the connecting member to damp the impact force propagating along the rear-axle stay.Type: ApplicationFiled: January 30, 2009Publication date: October 29, 2009Inventor: Chao-Shun Yang

Publication number: 20090236820Abstract: A rear-wheels transmission and suspension system, adapted for modifying a two wheeled motorcycle into a motorcycle containing two rear wheels, includes a suspension device, a rear axle and a transmission device. The suspension device includes a supporting frame longitudinally extending along the central axis of a construction frame and pivotally connected with a seat portion of the construction frame of the motorcycle for supporting the rear axle at the rear end the supporting frame while defining a transmission cavity after a rear end of the supporting frame and at a central position behind an output of said engine along the central axis of the construction frame. Therefore the transmission device is able to be supported by the rear axle in the transmission cavity to transmit a rotation output from the engine to drive the rear axle to rotate for driving the rear wheels to rotate.Type: ApplicationFiled: May 28, 2009Publication date: September 24, 2009Inventors: Liang Chang, Xin Hua Chen
