Braking system equipped with cooling means

摘要

The invention relates to a braking system (1) including:
a dynamic brake (10), including a hydraulic ram (11), including a cylinder (12), a piston (13) movable in the cylinder (12), and a chamber (14) capable of being filled to displace the piston within the cylinder and actuate the brake,a circuit (20) for feeding the brake, including a reservoir (21) a pump (22) and a brake feed line (26),

a brake control device (30), including a fluid pressure regulating valve (32) in the brake chamber, and progressive control (31), the valve including a path connected to the feed line, a path connected to the reservoir, and a path connected to the brake chamber, and being designed to selectively connect the path connected to the chamber to one or the other of the other paths, to deliver a predetermined pressure into the chamber according to a degree of actuation of the control,

the braking system being characterized in that it further includes a chamber cooling line (40), designed to renew the fluid contained in the chamber to ensure cooling of said chamber.

1. A braking system including:
a dynamic brake, including a hydraulic ram, containing a cylinder, a piston movable within the cylinder, and a chamber-capable of being filled to displace the piston within the cylinder and actuate the brake, a brake feed circuit, including a reservoir, a pump and a line for feeding the brake, a brake control device, including a fluid pressure regulating valve in the brake chamber, and a progressive control, said device being designed to deliver a predetermined pressure into the chamber depending on the degree of actuation of the control,wherein the fluid pressure regulating valve includes an inlet/outlet port connected to the feed line, an inlet/outlet port connected to the reservoir and an inlet/outlet port connected to the brake chamber,the fluid pressure regulating valve being designed to selectively connect the inlet/outlet port connected to the chamber to one or the other of the other ports depending on the pressure in the chamber and on the degree of actuation of the control,and in that it further includes a cooling line of the chamber, designed to renew the fluid contained in the chamber to provide cooling for said chamber.
