Abstract
System, method, and devices related to a wheel speed sensor that includes a wireless communication device and a motion sensor. The motion sensor includes an accelerometer. The wireless communication device and motion sensor are disposed in a housing. The housing is attached to an attachment member. The attachment member is selectively attached to a wheel of a towed vehicle.
Claims10
A wheel speed sensor device for a towed vehicle, comprising:
- a housing;
- an accelerometer housed within the housing;
- a wireless communication device coupled to the accelerometer and housed within the housing;
- and
- an attachment mechanism operatively attaching the housing to a lug nut of a wheel of the towed vehicle, the attachment mechanism comprising an attachment member having a first end and a second end, the first end having at least two prongs extending therefrom and defining a generally annular opening for receiving the lug nut and a spring extending from the second end thereof, a setscrew, and a setscrew sleeve, wherein the setscrew sleeve is shaped to slidingly receive the attachment member therein and the housing is shaped to slidingly receive the setscrew sleeve therein such that tightening the setscrew into the setscrew sleeve forces the housing and the setscrew sleeve towards the lug nut forcing the prongs to be received in the setscrew sleeve compress the prongs against the lug nut thereby securing the attachment mechanism to the lug nut.
