ABSTRACT:
A hydrodynamic brake system for the wheel of a vehicle, particularly for the non-driven wheel of a trailer, forms an integral unit which is installed within the confines of the wheel rim at one side of the hub. The stator of the brake system is mounted on the non-rotating axle for the wheel, and the rotor of the brake system is connected with a reservoir for a supply of hydraulic brake fluid and is rotated by the hub and/or rim. The reservoir is connected by discrete feeding and evacuating conduits with a toroidal working chamber which is defined by the stator and rotor, and a portion of the reservoir is exposed to the surrounding atmosphere so as to promote the cooling of brake fluid therein. The brake fluid is forced into the chamber via feeding conduit and from the chamber back into the reservoir via evacuating conduits in response to admission of compressed gas into the reservoir whereby the fluid is heated in the chamber when the admission of gas takes place while the wheel rotates the rotor relative to the stator.
