Abstract
A method is provided for actuating a wet multiple disc brake, running with cooling oil, especially for a road vehicle. Stationary and rotating radially oriented discs are pressed against one another during braking while overcoming a clearance. The method is characterized in that once the brake is released, the discs associated with each other are separated from each other to such an extent as to form an oil-free or substantially oil-free clearance, wherein the clearance is minimized prior to braking by advancing the discs towards each another.
Claims14
A method for operating a multiple disc brake for a road vehicle, the multiple disc brake having stationary and rotating radially aligned discs that press against one another in an event of a braking operation, the multiple disc brake being run wet by use of cooling oil, the method comprising the acts of:
- releasing the brake after a braking operation;
- after releasing the brake, carrying away oil disposed between the aligned discs and separating the aligned discs from one another by an amount sufficient to avoid formation of a cooling oil film between mutually facing friction surfaces of the aligned discs;
- and
- advancing the aligned discs to minimize a substantially oil-free release clearance before another braking operation.
