摘要： An improved anti-lock brake device of simple and compact construction adapted for use with a motorcycle having front and rear master cylinders for actuating front and rear wheel brakes, respectively. The front master cylinder has a first brake chamber for producing a brake torque for a front road wheel and a first control chamber for controlling the brake torque so as to prevent locking of the front wheel. The rear master cylinder has a second brake chamber for producing a brake torque for a rear road wheel and a second control chamber for controlling the brake torque so as to prevent locking of the rear wheel. The control chambers are each in communication with a single common source of oil pressure through a first control valve and with an oil tank through a second control valve.

摘要： A shift control device in a hydrostatic continuously variable transmission in which a hydraulic closed circuit is formed between a swash plate type hydraulic pump and a swash plate type hydraulic motor, and a swash plate holder for supporting a motor swash plate of the hydraulic motor is tiltably supported on a stationary structure through a trunnion shaft fixedly mounted on the swash plate, wherein a drive shaft of a reversible electric motor is connected to the trunnion shaft through a reduction device which is constructed so that it transmits the rotation of the electric motor to the trunnion shaft at a reduced speed, but is brought into a locked state upon receipt of a reverse load from the trunnion shaft. This enables light adjustment of the tilting angle of the motor swash plate by use of a small-sized electric motor and reliable holding of the motor swash plate in a position at any angle.
