DRUM BRAKE DEVICE SUITABLE FOR INCLUDING A PARKING BRAKE THAT IS CONVENTIONAL OR THAT OPERATES IN DUO SERVO MODE |
摘要 |
<p>The invention relates to a drum brake device of a road vehicle, in particular for a motor vehicle. Said drum brake can operate as a service brake and as a parking or emergency brake. In service brake mode, a first actuator separates two movable ends of the brake shoes mounted on a plate that can rotate relative to the drum, while the opposite ends thereof both abut against an anchor element, performing a "simplex" type operation. According to the invention, the mechanism of said drum brake is mounted on a plate provided such as to be able to receive, as required: a stop plate which can be used as an anchor element for the simplex mode, in service brake mode by actuating the first actuator and in parking brake mode by pulling a lever actuated by a cable; or a second actuator separates the abutment ends of the brake shoes from one another while the movable ends thereof engage one another by means of a free element inserted relative to the plate, performing a "duo servo" type operation. The invention also relates to a vehicle including such a drum brake, and to a method for assembling such a drum brake including a step of selecting between mounting a basic stop plate or a second actuator.</p> |
