Abstract
Official abstract text for this publication.
A spring-type brake actuator for a vehicle brake such as a pneumatically-actuated brake is provided, in which the actuator's operating rod is pulled toward the actuator to apply the brake. The actuator's parking brake release piston is located closer to the brake than the service brake piston, and the parking brake power spring is positioned between the mounting end of the actuator and the parking brake piston such that when parking brake release pressure is removed from the parking brake release chamber the parking brake piston biases the operating rod in the brake application direction, drawing the operating rod further into the actuator. The operating rod may penetrate the parking brake piston and an intermediate flange between the parking brake piston and the service brake piston, and be connected to the service brake piston such that the service brake piston may control brake application when the parking brake piston is in its parking brake release position adjacent to the end of the actuator that is mounted to the brake.
First claim
Opening claim text (preview).
What is claimed is: 1. A spring brake actuator, comprising: an intermediate flange; a parking brake housing portion affixed at a flange end to a first side of the intermediate flange, the parking brake housing portion having a mounting end opposite the flange end and having a parking brake piston and a power spring disposed therein with the power spring between the mounting end and the parking brake piston; a service brake housing portion affixed to a second side of the interm…
