发明名称 Straddle-type vehicle
摘要 A straddle-type vehicle includes an input shaft connected to a rear drive shaft and extending in a front-rear direction of the vehicle, an output shaft connected to an axle and configured to rotate by receiving a driving force from the input shaft, a brake operator on which an operation is performed to brake the input shaft, a plate group disposed between a wall portion of a housing and a cam member, a cam plate disposed between the cam member and the plate group, an operation shaft extending in a direction perpendicular or substantially perpendicular to an axial direction of the input shaft, a first engagement protrusion protruding from the cam plate, a second engagement protrusion protruding from the operation shaft and engaging with the first engagement protrusion, a lever rotatable together with the operation shaft, and an operation cable connected to the brake operator and the lever.

主权项 1. A straddle-type vehicle comprising: a power unit; a drive shaft connected to the power unit and extending in a front-rear direction of the vehicle, the drive shaft being configured to rotate by receiving a driving force from the power unit; an input shaft connected to the drive shaft and extending in the vehicle front-rear direction; a housing including a wall portion facing rearward or frontward and in which at least a portion of the input shaft is housed; an output shaft connected to an axle and extending in a right-left direction of the vehicle, the output shaft being configured to rotate by receiving a driving force from the input shaft; a brake operator configured to have an operation performed thereon to brake the input shaft; a cam member disposed inside the housing and spaced away from the wall portion of the housing in the vehicle front-rear direction; a plate group disposed between the wall portion of the housing and the cam member, the plate group including annular rotation plates attached to the input shaft so as to be rotated together with the input shaft, and annular fixed plates each disposed between an adjacent one of the rotation plates and the cam member and/or between an adjacent one of the rotation plates and the wall portion of the housing; and an annular cam plate disposed between the cam member and the plate group; wherein the cam member and/or the cam plate are/is provided with a cam groove including an inclined surface; the straddle-type vehicle further comprises: a cam ball located between the cam member and the cam plate and disposed inside the cam groove;a rotatable operation shaft passing through the housing and extending in a direction perpendicular or substantially perpendicular to an axial direction of the input shaft, the operation shaft including an inner portion located inside the housing and an outer portion located outside the housing;a first engagement protrusion disposed inside the housing and protruding outward from the cam plate in a radial direction of the cam plate;a second engagement protrusion protruding outward from the inner portion of the operation shaft in a radial direction of the operation shaft, and engaging with the first engagement protrusion;a lever attached to the outer portion of the operation shaft and rotatable together with the operation shaft; andan operation cable connected to the brake operator and the lever.
