Patent number: 7357209Abstract: To provide an electromotive power assisted bicycle enabling an aerobic exercise with a light weight and simple mechanism, an electromotive power assisted bicycle 1 comprises a pedal effort detection means for detecting a pedal effort (99, 126), a drive unit 13, a force combining mechanism for transmitting a rotational torque of a speed reducing unit to a drive shaft, and a heart rate detection sensor 254. The drive unit 13 comprises an electric motor 37 and a speed reducing unit 35 having an electromagnetic clutch 250. In a mode enabling the aerobic exercise, if the detected pedal effort is higher than the pedal effort level enabling the aerobic exercise, the drive unit 13 drives the electric motor 37 under the condition of the electromagnetic clutch 250 being engaged and thus assists the pedal effort with the electric force.Type: GrantFiled: February 3, 2003Date of Patent: April 15, 2008Assignees: Sunstar Giken Kabushiki Kaisha, Sunstar Suisse SAInventors: Kyosuke Kokatsu, Akihito Yoshiie, Fumihito Nigara

Patent number: 7258216Abstract: A power-assisted bicycle is provided with a one-way clutch that can also be used as a torque detection apparatus. The one-way clutch has a tooth part (112) mounted on a driven means and a piece part (100) mounted slidably yet non-rotatably on a drive shaft (4). The tooth part has a first engagement face (121) formed with a plurality of teeth (114) and the piece part has a second engagement face (110) formed with a plurality of pieces (102). The first engagement face and the second engagement face are disposed facing each other generally perpendicularly to the axial direction. A disc spring (124) is disposed on the rear face of the piece part. As the piece part rotates in the direction of running forward, the piece is engaged with a sharply sloping face of the tooth to engage with the tooth and the angle of the piece with respect to the second engagement face increases, whereby the piece slides so as to increase the distance from the tooth part in resistance to the disc spring.Type: GrantFiled: April 5, 2005Date of Patent: August 21, 2007Assignees: Sunstar Giken Kabushiki Kaisha, Sunstar Suisse SAInventors: Akihito Yoshiie, Kyosuke Kokatsu
