Patent number: 8141892Abstract: A steering lock structure for a vehicle with a saddle includes a steering lock mechanism and left and right frame members. The steering lock mechanism is disposed rearwardly with respect to a head pipe to lock and unlock a rotation of a steering system. The left and right frame members extend in a vehicle rearward direction from the head pipe. The steering lock mechanism is disposed between the left and right frame members. The steering lock mechanism is configured to cause a lock pin to carry out a stroke movement along a vehicle upward and downward direction. The steering lock mechanism is configured to cause the lock pin to be brought into and out of engagement with a top bridge of the steering system which is supported on the head pipe. Thereby, locking and unlocking of the rotation of the steering system are allowed.Type: GrantFiled: February 23, 2010Date of Patent: March 27, 2012Assignee: Honda Motor Co., Ltd.Inventors: Yutaka Nakanishi, Tomoya Yoshizawa, Yoshiaki Takeuchi, Hiroshi Nishijima, Masakazu Kadota, Hidekuni Kawasaki

Patent number: 7665563Abstract: To restrain an increase in the numbers of components and process steps and achieve an easy mounting and dismounting of a pivot shaft. An arm supporting member includes a pair of left and right plate members, a middle cross pipe extending between the plate members and a center pivot plate mounted to the middle cross pipe. A pivot shaft is supported by the plate member and the center pivot plate, and a drive shaft is arranged between the plate member and the center pivot plate. The middle cross pipe is arranged above the pivot shaft on a front portion of a vehicle. The center pivot plate is provided with an upright wall as a receiving portion for aiding the positioning of the bearing member by receiving the bearing member, more specifically, the collar when assembling the swing arm to the center pivot plate and the plate member.Type: GrantFiled: January 9, 2006Date of Patent: February 23, 2010Assignee: Honda Motor Co., Ltd.Inventors: Kenichi Misaki, Yuzuru Ishikawa, Atsuhiko Takahashi, Masakazu Kadota, Atsushi Takasaki

Patent number: 6726483Abstract: A road simulation apparatus wherein front excitation means capable of exciting a front axle of a motorcycle upwardly and downwardly as well as forwardly and rearwardly is connected to the front axle of the motorcycle while rear excitation means capable of exciting a rear axle upwardly and downwardly is connected to the rear axle so that a road load proximate to that experienced by a motorcycle actually running on a road can be reproduces. A bendable link mechanism L comprised of a plurality of links La and Lb are disposed in the forward and rearward directions of the motorcycle for permitting mutual bending motion therebetween is connected for pivotal motion to a stationary support member S. The posture of the test vehicle body is maintained while the regeneration accuracy of road loads is augmented.Type: GrantFiled: May 6, 2003Date of Patent: April 27, 2004Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Shokichi Harashima, Masakazu Kadota

Patent number: 6546722Abstract: A partitioning member for dividing a connecting pipe into at least two exhaust passageways is provided in the connecting pipe, which is attached to an exhaust side of a silencer. A valve mechanism is operable to vary the passageway area of one of the exhaust passageways. With this structure, for example, when an engine is rotating at low revs, exhaust gas is discharged from the exhaust passageway without the valve mechanism, while when the engine is rotating at high revs exhaust gas is simultaneously discharged from the exhaust passageway having no valve mechanism and a passageway provided with the valve mechanism. Therefore, it is possible to reduce exhaust noise when the engine is rotating at low revs.Type: GrantFiled: November 29, 2001Date of Patent: April 15, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Mikio Sagara, Noritoshi Iwase, Kazuo Yamamoto, Masakazu Kadota, Hideo Koide, Yoshiaki Nakashima, Shinji Goto, Hiroaki Tsukui, Osamu Bunya
