Abstract
An elevator braking system comprises a wedge having a brake pad attachment section. The brake pad attachment section has a recessed brake pad receiving portion and a recessed side plate receiving portion. The system includes a brake pad having a notch. The brake pad is configured to be received within the recessed brake pad receiving portion. The system comprises a side plate having a fastener receiving portion and an overhanging portion that is perpendicular to the fastener receiving portion. The overhanging portion mates with the notch when the side plate is secured to the recessed side plate receiving portion.
Claims19
An elevator braking system, comprising:
- a wedge having a brake pad attachment section;
- said section having a recessed brake pad receiving portion and a recessed side plate receiving portion;
- a brake pad having a notch;
- said brake pad configured to be received within said recessed brake pad receiving portion;
- said notch disposed such that a back face of said brake pad is wider than a front face of said brake pad;
- a wedge bearing race having a curved surface configured to self-align with a roller bearing during a braking operation;
- said wedge bearing race being coupled to said wedge;
- and
- a side plate having a fastener receiving portion and an overhanging portion that is perpendicular to said fastener receiving portion;
- said side plate having a length shorter than an adjoining side of said brake pad;
- wherein, said overhanging portion mates with said notch when said brake pad is received within said recessed brake pad receiving portion and said side plate is secured to said recessed side plate receiving portion.
A method for coupling a brake pad to a wedge, comprising:
- providing an elevator braking system, comprising:
- said wedge having a front surface and a side surface;
- said brake pad;
- and
- a side plate having a fastener receiving portion and an overhanging portion that is perpendicular to said fastener receiving portion;
- said side plate having a length shorter than an adjoining side of said brake pad;
- forming a recessed brake pad receiving portion in said front surface and a recessed side plate receiving portion in said side surface;
- forming a notch in said brake pad such that a back face of said brake pad is wider than a front face of said brake pad;
- situating said brake pad in said recessed brake pad receiving portion;
- and
- securing said side plate to said recessed side plate receiving portion such that said overhanging portion mates with said notch to clamp said brake pad to said wedge.
An elevator braking system, comprising:
- a wedge having a front face and a side face;
- said front face including a brake pad receiving portion;
- said side face including a side plate receiving portion;
- a brake pad having a notch;
- said notch disposed such that a back face of said brake pad is wider than a front face of said brake pad;
- said brake pad being situated in said brake pad receiving portion;
- and
- a side plate configured to be secured within said side plate receiving portion such that a part of said side plate mates with said notch;
- said side plate having a length shorter than an adjoining side of said brake pad.
