Document Type and Number:
WIPO Patent Application WO/2010/119531
Kind Code:
A1
Abstract:
A two-wheeled motor vehicle wherein a time period in which hydraulic oil, in which air is mixed due to a tilt of a vehicle body in the left-right direction, stays in an oil path is reduced. A two-wheeled motor vehicle is provided with an oil pump (58) for sending hydraulic oil to an oil chamber (37) of a primary pulley (31) and to an oil chamber (38) of a secondary pulley (32), and also with a first control valve (56). The first control valve (56) has a discharge port (56b) for discharging hydraulic oil from a first oil path (81) leading from the oil pump (58) to the oil chamber (37). A control device operates, as normal control thereof, the first control valve (56) based on operating conditions of the vehicle. Also, the control device determines whether or not the tilt of the two-wheel motor vehicle has exceeded a predetermined threshold value and, if the tilt has exceeded the predetermined threshold value, operates the first control valve (56) so as to suppress closure of the discharge port (56b).
