Abstract
In the combination of a rotating member such as an automotive vehicle wheel, a brake operative for slowing the rotating member or wheel, and a sensor for signalling any occurrence of an excessive rate of retardation of the rotating member or wheel, an improvement which facilitates optimum response of the sensor by varying the sensitivity or responsiveness of the sensor upon variations in a vehicle operating condition such as the weight imposed on the rotating member or wheel or the braking pressure. In specific forms disclosed, variation in sensitivity of the sensor is accomplished by a variable ratio transmission means mechanically interposed between the sensor and the rotating member or wheel and which is responsive to vehicle operating conditions.

In the combination of a rotating member, a brake operative for slowing the rotating member, and a sensor operatively coupled to the rotating member for signalling any occurrence of an excessive rate of retardation of the rotating member, an improvement which facilitates optimal response of said sensor comprising a variable ratio transmission coupling means operatively interposed between said sensor and said rotating member and operatively responsive to a predetermined operating condition of the rotating member for varying the sensitivity of said sensor upon variations in said condition.
In an automotive vehicle having a rotating wheel, a brake operative for slowing the rotating wheel, and a sensor operatively coupled to the wheel for signalling any occurrence of an excessive rate of retardation of the wheel, an improvement which facilitates optimal response of said sensor comprising a variable ratio transmission coupling means operatively interposed between said sensor and said rotating member and operatively responsive to a vehicle operating condition for varying the sensitivity of said sensor upon variations in said condition.
In the combination of a rotating member, a brake operative for slowing the rotating member, and a sensor mechanically connected to the rotating member for rotation at speeds proportionate to the rotating member speeds and for signalling any occurrence of an excessive rate of retardation of the rotating member, an improvement which facilitates optimal response of said sensor comprising a variable ratio transmission coupling means mechanically interposed between said sensor and said rotating member and operatively responsive to a predetermined operating condition of the rotating member for varying the sensitivity of said sensor upon variations in said condition.
