Abstract
An electromechanical brake assembly 10 having a pair of selectively movable and dissimilar self energization wedge members 24, 26 which are respectively and independently controlled by motors 30, 34, and which have respectively dissimilar angles of inclination 60, 62, thereby providing a controllably varying amount of self energization.
Claims14
A brake assembly including a pair of selectively movable members each having a respectively unique angle of inclination;
- and a controller assembly which is coupled to said pair of selectively movable members and which selectively causes said pair of selectively movable members to cooperatively provide a controllably varying amount of self energization, wherein said controller assembly comprises a controller which is operable under stored program control;
- a first motor which selectively moves said first of said pair of members and which is coupled to said controller;
- and a second motor which selectively moves said second of said pair of members and which is coupled to said controller.
A method for braking a vehicle of the type having at least one selectively movable wheel, said method comprising the steps of providing a rotor;
- coupling said rotor to said at least one wheel;
- providing a backing plate;
- providing at least one brake pad;
- coupling said at least one brake pad to said backing plate;
- providing a first wedge;
- coupling said first wedge to said backing plate;
- providing a second wedge;
- movably coupling said second wedge to said first wedge;
- providing a first and a second motor coupling said first motor to said first wedge;
- coupling said second motor to said second wedge;
- causing said first motor to move said first wedge against said second wedge and against said brake pad, effective to cause said at least one brake pad to frictionally engage said rotor, thereby braking said vehicle.
