Title:
HYDRAULIC BRAKING SYSTEM WITH SAFETY FUNCTIONS AND ANCILLARY FUNCTIONS FOR FARM VEHICLES AND THE LIKE, AND METHOD FOR CONTROLLING THE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/115216
Kind Code:
A1
Abstract:
A hydraulic braking system (1) includes: an anti-lock hydraulic braking device (10) arranged to manage safety functions and ancillary functions based on interventions on braking members of the vehicle; brakes (17, 18, 19, 20) fed by a second fluidic circuit (12) containing a second fluid incompatible with the first fluid; and bi-fluidic relays (35 to 38) connected between the anti-lock braking device (10) and the brakes (17 to 20) and configured for hydraulically separating the first fluidic circuit (11) from the second fluidic circuit (12). The vehicle has two braking pedals (13, 14) connected to two master cylinders (15, 16), respectively, configured each for actuating braking by means of a front brake and/or a rear brake (17, 20) located on a same side of the vehicle. Each master cylinder (15, 16) has a first brake actuation circuit (28, 29) connected with a section of the anti-lock braking device (10) intended for controlling a respective rear brake (17, 20), and a second brake actuation circuit (25, 26) connected with a respective inlet of a logic head (27) with two inlets and one outlet (43), where the outlet (43) is connected with a section of the anti-lock braking device (10) intended for controlling the front brakes (18, 19). The anti-lock braking device (10) is associated with a selector (30) operable by a user of the vehicle for turning on or off the anti-lock braking device (10) at least during steer-by-braking.
