Title:
LEANING VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/146774
Kind Code:
A1
Abstract:
A leaning vehicle 1 equipped with a rubber belt-type continuously variable transmission device (30) wherein the degree of freedom in the control of braking force applied to a rear wheel (3) by engine braking is further improved. This leaning vehicle 1 comprises a body frame (7) that inclines in the lateral direction of the vehicle, an engine (20) including a crankshaft (21), a front wheel (2), a rear wheel (3), the rubber belt-type continuously variable transmission device (30) that transmits power from the crankshaft (21) to the rear wheel (3); and a rear wheel braking force control device (120). The rear wheel braking force control device (120) includes at least one of an electric actuator (70) that changes the winding diameter of the rubber belt (32) of the rubber belt-type continuously variable transmission device (30), a crankshaft motor generator (90) that applies torque to the crankshaft (21), and a rear wheel motor generator (80) that applies torque to the rear wheel (3). The rubber belt-type continuously variable transmission device (30) is configured so that the difference between the maximum speed ratio and the minimum speed ratio is larger than the rubber belt variation. The rear wheel braking force control device (120) controls, at least after the leaning vehicle (1) reaches the maximum speed and shifts to a deceleration state, the braking force to be applied to the rear wheel (3).
