Abstract: Bolt holes 23 are provided for press fitting and securing bolts 5 for mounting a brake rotor 4 to a flange 22 of a hub wheel. Each bolt hole 23 includes widening portions 28a, 28b, which are tapered to widen from the center portion of the bolt hole 23 toward a brake rotor mounting surface 25 of the flange 22. The widening portions 28a, 28b are formed by two tapered surfaces having different taper angles with respect to the axis of the bolt hole 23 from an opening rim of the bolt hole toward the inside. The taper angle of an outer tapered surface connected to the opening rim is greater than the taper angle of an inner tapered surface connected to the outer tapered surface. In machining the hub wheel 2 configured as described above, the brake rotor mounting surface 25 is finished after machining the bolt holes 23.

Abstract: In a driving force control apparatus for an automotive vehicle employing an engine that drives a main drive wheel, a generator driven by the engine, and a motor driven by an electric power output generated by the generator to drive a subsidiary drive wheel, a subsidiary-drive-wheel acceleration slip estimation circuitry is provided to estimate a subsidiary-drive-wheel acceleration slip rate. An electric power output suppression circuitry is provided to suppress the electric power output of the generator when the estimated subsidiary-drive-wheel acceleration slip rate exceeds a predetermined slip rate.

Abstract: A drive control device is provided with a determining section and a voltage increasing section. The determining section determines if the actual acceleration is deficient in comparison with the acceleration requested by the driver or if the generator output is deficient in comparison with the acceleration requested by the driver. The voltage increasing section increases the voltage supplied to the electric generator from a vehicle mounted electric power source when the determining section determines that the actual acceleration or the generator output is deficient. As a result, the generator output deficiency is eliminated and the required motor torque is produced, thereby enabling the vehicle to start into motion appropriately in accordance with the acceleration requested by the driver.

Abstract: A vehicle drive force control apparatus is provided that can stabilize the output of the electric motor even if the engine rotational speed experiences an acute change. The output of an engine is delivered to the left and right front wheels through a transmission and also to an electric generator. The output voltage of the electric generator is supplied to an electric motor and the output of the electric motor drives the left and right rear wheels. The drive force control device predicts if the rotational speed of the engine will decrease or increase acutely based on the upshifting and downshifting of the transmission and adjusts the field current of the electric generator up or down before the acute change in the engine rotational speed occurs.

Abstract: In a vehicle drive system, a pair of rear wheels is driven by first and second motors. The first motor is designed to specifications suited to delivering torque at low rotational speeds and the second motor is designed to specifications suited to delivering torque at high rotational speeds. The motor used to drive the rear wheels is selected based on the vehicle speed. The change in the operations of the first and second motors is synchronized with a shifting of a transmission disposed between an engine and a pair of front wheels. Thus, the vehicle drive system is configured and arranged to accommodate speeds ranging from low speeds to high speeds in a sufficient manner without requiring the drive source to become large.

Abstract: A driving force control apparatus is provided to prevent shocks from being generated during clutch engagement or release. The clutch is maintained in an engaged state and shocks are prevented from accompanying clutch release during creep travel when the target motor torque is equal to or less than a motor torque prescribed value but the average rear wheel speed, which is equivalent to the travel speed of the auto vehicle, is equal to or less than a low-speed prescribed value. In addition, the drive torque on the rear wheels from the electric motor is also brought to the same level as the creep torque on the front wheels from the internal combustion engine, backlash and other types of gaps between the rear axles of the electric motor are closed, and shocks are minimized or prevented during the subsequent transition to a four-wheel drive state.

Abstract: A vehicle comprises a motor (4) and a wet clutch (12) for transmission of torque output of the motor to road wheels of the vehicle and transmission of road load from the road wheels to the motor (4). The wet clutch is disengaged in response to a clutch disengagement control signal. Accounting for clutch drag state of the wet clutch, a controller (8) selects one out of various values as threshold (Voff). The controller (8) determines that the wet clutch be disengaged when a parameter indicative of the actual vehicle speed has a predetermined relationship with the threshold. The controller (20) generates the clutch disengagement control signal upon determining that the wet clutch be disengaged.

The output of an engine is delivered to the main drive wheels through a transmission and also to an electric generator. The output voltage of the electric generator is supplied to the electric motor and the output of the electric motor drives the subordinate drive wheels. When it is determined that the generator output voltage will not be sufficient to meet the requirement of the electric motor, the amount of acceleration slippage allowed at the left and front wheels is increased.

Abstract: A driving force control apparatus is provided for a vehicle capable of preventing a shock from being generated by disengaging a clutch disposed between a subordinate drive source and subordinate drive wheels during vehicle travel.
