Abstract
Abstract An installation for preventing the locking of the brakes in vehicles, in which sensing elements are provided at the wheels that produce an output signal corresponding to the wheel rotational speed which is fed to a common comparator; the sensing members are each arranged within the area of the wheel mounting outside of the inner and outer wheel bearing.

Claim 1
Independent Claim
191 words
An installation for the brake locking prevention of vehicles, in which sensing means are provided at the wheels producing an output signal corresponding to the wheel rotational speed, and in which a wheel mounting means including inner and outer bearing means rotatably support a respective wheel, characterized in that the sensing means are each arranged within the area of the wheel mounting outside of the inner and of the outer wheel bearing means, each sensing means being constructed as a frequency generator including a stator and a rotor, the stator being mounted at a relatively fixed part of the wheel mounting means and the rotor at a rotating part of the wheel bearing means, several coil means being mounted on the stator, the stator having the shape of a clamping flange means which is clampingly mounted with its inner diameter on the end disposed near the outer wheel bearing means of a fixed wheel hub support, said clamping flange means being provided at its outer diameter with several projecting yoke mountings corresponding to the number of coil means which are distributed substantially uniformly over the circumference of the clamping flange means.
Claim 2
Dependent Claim
