Abstract
An S-cam brake system having is disclosed. The system includes a roller assembly, an S-cam, a shoe, and an S-cam brake. The roller assembly is configured to allow relative movement between a roller and a roller pin. The roller assembly is interposed between the S-cam and the shoe. Relative movement between a roller and a roller pin can compensates a defect in machining the outer contact surface of the S-cam roller or a defect in concentricity of roller seating depressions of the shoe.
Claims17
An S-cam brake system comprising
- a roller pin, and a roller having a pin hole into which the roller pin is inserted,
- wherein the pin hole has an inner circumferential surface with a predetermined curvature as a pin contact surface, and due to the curvature, a contact section and a non-contact section are formed between the inner circumferential surface of the pin hole and an outer circumferential surface of the roller pin so that relative movement of the roller and relative movement of the roller pin are generated between the roller and the roller pin.
