Load regulated dual braking circuit - has common regulator to vary relative braking on axes w.r.t. loading of motor vehicle

摘要

The dual braking circuit is operated by two main brake valves (3,4) operated from the same brake control linkage (21). The proportional control is operated by a yoke (14a) whose setting is adjusted by a control cylinder (11) driven from the load sensing circuit. The two brake valves are then operated w.r.t. the loading distribution on the two axles. For a tandem brake cylinder the pressure between the two pistons is regulated by the load sensing circuit to alter the relative reaction of the two circuits. No separate pressure control means are required in the two circuits. ADVANTAGE - Simplified dual control circuit. Faster response.
