Abstract: An improved self-adjusting automatic slack adjuster for reducing slack in the brake of a vehicle is provided, in which an easily accessible external operating feature permits the automatic slack adjuster's one-way clutch assembly to be readily disengaged to allow smooth release and retraction of the brake shoes of a vehicle brake without damage to the one-way teeth of the clutch assembly. When the external feature is operated in a brake release direction, the motion of the feature is translated into a motion which axially displaces an output part of the one-way clutch away from an input part of the clutch a distance sufficient to disengage the parts' one-way teeth, thereby disengaging the one-way clutch to permit brake shoe retraction without resistance from the one-way clutch.

Abstract: A hydraulic damper assembly includes a main body, a shaft assembly and a main piston operatively configured to define an upper portion and a lower portion within the main body. A hydraulic damper spool valve is adapted to provide a single path, variable hydraulic flow restriction between the upper portion and lower portion of the main body. The hydraulic damper spool valve is configured with an array of precisely shaped flow apertures that are proportionally opened and closed by a pair of valve spools in response to the pressure differential across the main piston. The damper's pressure-flow operating characteristic is simply and predictably dictated by the geometric configuration of the shaped flow apertures. The precisely defined open area of the shaped flow apertures provides a mathematically predictable hydraulic flow restriction that operates predominately in a turbulent regime resulting in insensitivity to hydraulic fluid viscosity and consequently temperature change.

Abstract: In a vehicle capable of performing regenerative braking and fluid pressure braking, in changing from the regenerative braking to the fluid pressure braking in response to a decrease of a vehicle speed due to braking, a fluid pressure braking force is increased from 0 at a first increasing rate when the vehicle speed falls to or below a first threshold value (V1), and the fluid pressure braking force is increased at a second increasing rate, which is higher than the first increasing rate, when the vehicle speed falls to or below a second threshold value (V2), which is smaller than the first threshold value (V1). With this configuration, while occurrence of a squeal noise of a wheel cylinder can be prevented by setting the first increasing rate of the fluid pressure braking force at a small value, a required braking force can be generated without any problem by setting the second increasing rate, to be used subsequently thereto, of the fluid pressure braking force at a large value.
