Abstract
A bushing assembly adapted for application in vehicle suspension systems includes an embedded position sensor and an embedded speed sensor.
Claims20
A bushing assembly comprising:
- an outer member;
- an inner member arranged substantially concentrically with the outer member;
- an elastomeric member disposed between and interconnecting the inner and outer members;
- and
- a speed sensor at least partially embedded within the elastomeric member and operative to produce an output signal indicative of the relative speed between the inner and outer members.
2 more elements
A speed sensing system, comprising:
- at least one bushing assembly including a moving part, a non-moving part, and at least one elastomeric material therebetween, at least one sensor being disposed at least partially in the elastomeric material and generating a signal representing at least one parameter selected from the group including:
- relative position between the parts, and relative speed between the parts;
- and
- means receiving the signal for outputting a speed signal representing relative speed between the parts.
1 more element
A bushing assembly for a vehicle, comprising:
- a stator engageable with a first part of a vehicle;
- a rotor engageable with a second part of the vehicle;
- a resilient material disposed between the stator and rotor;
- and
- at least one speed sensor engaged with the rotor or the stator for outputting a signal that is directly proportional to the relative speed between the parts without having to differentiate the signal with respect to time.
