The brake system comprises a first actuator (5) for increasing a liquid pressure in a master cylinder (2) by driving torque of a motor (51), and a second actuator (6) capable of driving a brake generating mechanism (3) without transmitting power to the master cylinder (2), wherein the actuators (5, 6) to be driven are switched depending on the operation of a brake pedal (1). The first and second actuators (5, 6) are connected to hydraulic piping (4f, 4r), and a pressurized oil is supplied to the brake generating mechanism (3) through hydraulic valve means (63f, 63r, . . . 65rr).

摘要： A steering system includes a hydraulic power cylinder 5 that assists a steering force of a rack-and-pinion mechanism 4, and a first hydraulic pressure supply mechanism 8 having a first trochoid pump 23 selectively supplying hydraulic pressure to two hydraulic pressure chambers 15a and 15b of the hydraulic power cylinder via first and second fluid passages 6 and 7, and a first electric motor 24 for the first trochoid pump. When the first hydraulic pressure supply mechanism becomes failed, a second hydraulic pressure supply mechanism 11 is operated responsively to a command signal from a control unit 14 to selectively supply hydraulic pressure via third and fourth fluid passages to either one of the hydraulic pressure chambers.Thus, it is possible to positively apply a steering assist force by means of the second hydraulic pressure supply mechanism 11, thereby reducing a driver's operating force applied to a steering wheel.

摘要： In order to realize cost reduction in a gear pump apparatus by reducing form accuracy of a gear while securing pump performance, a running-in coating is provided on a tooth sliding contact portion when forming a confinement area in at least one of gears of the gear pump apparatus. By this feature, the running-in coating is gradually worn away and deformed according to rotary drive of the pump, and thus it is possible to obtain an optimal gear form in meshing combinations of the gears. Further, it is possible to reduce leakage inside the pump to secure the pump performance even if the form accuracy of the gear is reduced for the sake of the cost reduction.

摘要： In a power steering system comprising a power cylinder for assisting a steering power of a steering mechanism, a hydraulic pump for supplying a hydraulic pressure to the power cylinder, a first oil passage and a second oil passage connecting the power cylinder and the hydraulic pump respectively, a motor for driving the hydraulic pump, and power steering control means for calculating a command value to the motor based on the steering torque, a flow rate of the working oil supplied from a high-pressure side oil passage to a low-pressure side oil passage is restrained at the transition from the end of the steering state (lock end) of the steering mechanism to the returning. The flow-rate restraint increasingly corrects a driving current of the motor in the steering direction or limits the flow rate of the working oil.
