  • Patent number: 10578192
    Abstract: A degree of freedom of a hypoid gear is improved. An instantaneous axis in a relative rotation of a gear axis and a pinion axis, a line of centers, an intersection between the instantaneous axis and the line of centers, and an inclination angle of the instantaneous axis with respect to the rotation axis of the gear are calculated based on a shaft angle, an offset, and a gear ratio of a hypoid gear. Based on these variables, base coordinate systems are determined, and the specifications are calculated using these coordinate systems. For the spiral angles, pitch cone angles, and reference circle radii of the gear and pinion, one of the values for the gear and the pinion is set and a design reference point is calculated. Based on the design reference point and a contact normal of the gear, specifications are calculated. The pitch cone angle of the gear or the pinion can be freely selected.

  • Patent number: 8172341
    Abstract: A vehicular anti-lock control system includes: a ground load calculation section for detecting or estimating a ground load of a wheel; a road surface friction coefficient calculation section for detecting or estimating a road surface friction coefficient; and a reference fluid pressure calculation section for calculating an upper side reference fluid pressure and a lower side reference fluid pressure in anti-lock control based on the ground load and the friction coefficient. The upper and lower side reference fluid pressures are respectively determined to be an upper limit value and a lower limit value of a fluid pressure in anti-lock control. Therefore, it is possible to suppress the amount of change in the fluid pressure during anti-lock control, thus improving the braking effect and the braking feel.

  • Patent number: 7488047
    Abstract: During normal operation in which a motor cylinder is operative, when a depressing force cut-off valve is closed, a front wheel is braked by operating a first wheel cylinder by brake fluid pressure generated by the motor cylinder. When there is an abnormality in which the motor cylinder breaks down, the front wheel is braked by supplying, via the opened depressing force cut-off valve, brake fluid pressure generated by a master cylinder operated by a driver's braking operation to the first wheel cylinder, and a rear wheel is braked by supplying the brake fluid pressure to a second wheel cylinder. Thus, since both the front and rear wheels are braked by the brake fluid pressure generated by the master cylinder in case of abnormality, a vehicle can be reliably stopped by a sufficient braking force.
