  • Patent number: 4618022
    Abstract: A power transfer device for a four-wheel drive vehicle comprises a first differential including a differential case arranged to be applied with drive torque from a transmission, a pinion gear rotatably mounted within the differential case, and a pair of side gears rotatably mounted within the differential case and in mesh with the pinion gear; a pair of output shafts connected to the side gears respectively for driving the front and rear road wheels; a second differential including a differential carrier formed to contain the differential case therein, a carrier rotatably mounted within the differential carrier and connected with the differential case for rotation therewith about a common axis, a sun gear integral with one of the side gears, a planetary gear rotatably supported by the carrier and in mesh with the sun gear, a ring gear integral with the inner wall of the differential carrier and in mesh with the planetary gear, the carrier being drivingly connected to an output shaft of the transmission; and a

  • Patent number: 4315563
    Abstract: In order to suppress squeak noise generated at the time of braking of a disc brake, there is provided a member for removing abrasion powder as well as a conventional pair of friction pads which are provided on both sides of the disc. The member is designed so as to remove abrasion powder adhering to the disc at the time of engagement of the disc with the friction pads.

  • Patent number: 4225021
    Abstract: An anti-squeal shim used in a disc-brake, wherein a disc is urged by a friction pad assembly (or assemblies), as an insertion placed between the pad assembly and an urging means for pressing the pad assembly onto the disc, which shim is made solely of metal, in particular aluminum or aluminum-based alloy, or brass, with the object of enhancing the durability as well as the squeal preventing ability.

  • Patent number: 4181370
    Abstract: A fluid pressure control device comprises an inertia-controlled valve for interrupting the flow of fluid from a master cylinder to rear wheel brake cylinders when a ball is subjected to a deceleration in excess of a predetermined value. In the control device, a bypass passage is provided to permit direct fluid flow from a valve chamber into an outlet chamber, the valve chamber being in communication with an inlet chamber and containing the ball therein, and a check valve is disposed within the bypass passage to normally interrupt the direct flow of fluid from the valve chamber to the outlet chamber, the check valve being opened to cause the direct flow of fluid from the valve chamber to the outlet chamber when a pressure difference is produced between the valve chamber and the outlet chamber after the inertia-controlled valve is closed.

  • Patent number: 3969001
    Abstract: A hydraulic braking system for a vehicle is provided wherein a hydraulic brake pressure control device which includes a solenoid valve and a switching valve is arranged in a rear brake hydraulic circuit of the system. The solenoid valve applies braking fluid pressure on the wheel cylinder side of the braking system to an accumulator when wheel lock occurs and thereby lowers the wheel cylinder fluid pressure by increasing the volume within the circuit on the wheel cylinder side. The switching valve cuts off the rear brake hydralic circuit by means of an interlocking operation with a piston of the accumulator. Thus, the wheel lock is released and a relief valve or a pressure regulator is provided in parallel with the hydraulic brake pressure control device so that after release of the wheel lock the wheel cylinder fluid pressure is raised in correspondence with the relationship of allotted braking forces between the front and rear wheels.
