The electromagnetic brake includes a multiplate brake mechanism, a ringlike core member fixed through an annular brake guide inside the fixed housing, an exciting coil accommodated in an annular groove formed on the core member, and a ringlike armature member arranged radially outside of the core member. Each of the core member and the armature member has a plurality of tapering surfaces. The tapering surfaces of the core member are respectively complementary in shape to the tapering surfaces of the armature member. The electromagnetic brake further includes a cylindrical pressure member movable in a direction of pressing the multiplate brake mechanism. The cylindrical pressure member has one end fixed to the armature member and another end engaged with the multiplate brake mechanism.

摘要： Two sensors are provided on a clutch core. Sensor coils are driven at a high frequency by a high-frequency driving circuit. As the sensors sense a magnetic flux of a magnetic circuit including the clutch core and an armature, the impedance of the sensor coils changes. In accordance with the outputs from the sensor coils at this point, an impedance detecting circuit detects the impedance of the sensor coils. Then, an impedance combining circuit combines the impedance of the sensor coils. On the basis of the combined impedance, a current control circuit controls a current supplied to an exciting coil. Thus, the attracting force of the armature to the core excited by the exciting coil is controlled.

摘要： A driving force distribution device which controls the engagement forces of electromagnetic clutches and which govern the torque distribution between the driving wheels of a vehicle by calculating a target magnetic flux density and converting the same into a target excitation current. Since the relationship between the target magnetic flux density and the target excitation current changes according to a decrease in the air gaps accompanying wear of the frictional engagement members of the electromagnetic clutches, a relationship between the magnetic flux density and the excitation current is determined by applying current to the electromagnetic clutches when torque distribution control is not being carried out such as when the system is started, and the target excitation current is calculated from the target magnetic flux density based on the determined relationship. Since there is no need to detect dynamic changes in the magnetic flux density, inexpensive devices can be used as magnetic flux density detecting means so contributing to a reduction in the cost.
摘要翻译：一种驱动力分配装置，其通过计算目标磁通密度并将其转换为目标励磁电流来控制电磁离合器的接合力并且控制车辆的驱动轮之间的转矩分布。由于目标磁通密度和目标激励电流之间的关系随着伴随电磁离合器的摩擦接合构件的磨损的气隙的减小而变化，所以磁通密度和激励电流之间的关系通过应用基于所确定的关系，根据目标磁通密度计算当系统启动时不进行转矩分配控制时的电磁离合器的电流。由于不需要检测磁通密度的动态变化，所以可以使用便宜的装置作为磁通密度检测装置，从而有助于降低成本。

摘要： In a vehicle in which a torque generated in an engine is transmitted to driven wheels through a torque converter and an automatic transmission, when a speed ratio e in the torque converter is equal to or larger than a predetermined value (e.g., 0.85), and the accuracy of estimating a capacity &tgr; of the torque converter is low, an estimated engine torque Ti is multiplied by a torque ratio k of the torque converter to estimate a drive torque Td. When the speed ratio e in the torque converter is smaller than the predetermined value, and a response lag is produced in the transmission of the engine torque, a drive torque Td is estimated from an engine rotational sped Ne and the speed ratio e in the torque converter. During shifting of the automatic transmission, a drive torque Td is estimated from a wheel speed V. Thus, a correct drive torque can be estimated.
