Title:
VARIABLE CHARACTERISTIC LIMITED SLIP DIFFERENTIAL
Document Type and Number:
WIPO Patent Application WO/2023/209814
Kind Code:
A1
Abstract:
A differential used to distribute input torque comprises: a casing that receives input torque; a differential gear set that is housed in and supported by the casing, that comprises first and second side gears, and that differentially distributes the input torque to the first and second side gears; a clutch that is interposed between the casing and the first side gear, that frictionally brakes the first side gear against the casing, and that thereby limits a differential between the first side gear and the second side gear; an actuator that exerts a pressing force on the clutch to control the differential; and an electronic control device electrically connected to the actuator, the electronic control device being configured to calculate a lock rate from a selected differential torque ratio, calculate a required torque from a product obtained by multiplying the input torque by the lock rate, and control electric power supplied to the actuator in accordance with the required torque.
