Publication number: 20080283344Abstract: A vehicle braking system that eases assembly of a plurality of rotational friction plates and a plurality of fixed friction plates to a system body. The braking system can include a plurality of rotational friction plates and a plurality of fixed friction plates assembled on a periphery of an annular member such that each of the fixed friction plates is positioned between a pair of the rotational friction plates. A retaining member, such as a circlip, is engaged with each end of the annular member for preventing the rotational friction plates and the fixed friction plates from becoming disengaged with the annular member by axial movement. In addition, outer fixed friction plates can be positioned on each end of the collection of rotational friction plates and fixed friction plates.Type: ApplicationFiled: May 9, 2008Publication date: November 20, 2008Applicant: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventors: Ryuta Inoue, Seiji Nakagaki, Takeshi Ito

Publication number: 20080277210Abstract: A vehicle braking system that includes an interior space for accommodating a plurality of rotational friction plates and a plurality of fixed friction plates. The interior spaced is formed by a brake housing and a wheel hub, and lubrication oil for lubricating the plurality of rotational friction plates and the plurality of fixed friction plates is contained within the interior space. The brake housing includes a projection, or projection portion, which projects closer to center of an axle, along a longitudinal axis of the axle, than innermost surfaces of the rear wheels. In one arrangement, the projecting portion is located below the axle. In addition, one or more cooling fins can be provided on a surface of the projecting portion. Furthermore, in some arrangements, a space within the projecting portion projects closer to center of an axle, along a longitudinal axis of the axle, than innermost surfaces of the rear wheels.Type: ApplicationFiled: May 9, 2008Publication date: November 13, 2008Applicant: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventors: Ryuta Inoue, Seiji Nakagaki, Takeshi Ito
