  • Patent number: 11312381
    Abstract: A four-wheel drive force distribution apparatus for distributing drive forces to the wheels of a four-wheel drive vehicle, in which the distribution of drive force to the front inside wheel (2a) and the distribution of drive force to the rear inside wheel (3a) are adjusted based on a ground load of the front inside wheel (2a) and a ground load of the rear inside wheel (3a) when the vehicle is turning, and the distribution of drive force to the front inside wheel (2a) compared with distribution of drive force to the rear inside wheel (3a) is reduced the smaller the ratio of the ground load of the front inside wheel (2a) to the ground load of the rear inside wheel (3a) during turning.

  • Patent number: 10589560
    Abstract: This invention forms a good unrepellent uniform coating film and an image having neither image missing nor image blur by using an inkjet printing method. Active energy ray curing inkjet ink contains (A) an active energy ray curing monomer and/or an active energy ray curing oligomer, (B) a photopolymerization initiator, and (C) a surface tension adjusting agent, and has a viscosity of 3.0 to 6.0 mPa·s at 35° C.

  • Patent number: 7712561
    Abstract: A driving wheel structure (100) for a motor vehicle employing an in-wheel motor arrangement includes first (105) and second (108) electric motors for generating drive torques to rotate a wheel (102), a first support member attached to the vehicle body for supporting the first motor on a vehicle body, and a second support member attached to the vehicle body for supporting the second motor on the vehicle body. When the wheel (102) is rotated in one direction by the first motor (105), a reaction torque (F1) is induced in the first support member by the drive torque of the first motor (105) that applies a down-ward bias force (F1) to the wheel (102). When the wheel (102) is rotated in said one direction by the second motor (108), a reaction torque (F2) is induced in the second support member by the drive torque of the second motor that applies an upward bias force (F2) to the wheel (102).
