ELECTRONICALLY CONTROLLED FULL POWER BRAKE VALVE

摘要

A hydraulic braking system having an electronically controlled full power brake valve is disclosed. The hydraulic braking system supplies a braking output for a vehicle having at least one brake. The hydraulic braking system includes a primary valve assembly that is configured to receive a manually controlled input that varies the braking output of the braking system. The primary valve assembly includes a first spool valve configured to vary the braking output according to the manually controlled input. The hydraulic braking system also includes a secondary valve assembly is configured to receive input signals from a programmable electronic controller and includes a second spool valve configured to operate with the primary valve assembly. Th e secondary valve assembly also includes an actuator for engaging and actuatin g the second spool valve according to the input signals received from the programmable electronic controller such that the second spool valve modulate s the braking output produced by the primary valve assembly.
