Abstract
A double caliper braking system of differential action, operated by a pressure circuit with two parallel branches connected to the calipers. One of the brake calipers is of smaller dimensions than the other. One of the two branches is provided with a pressure regulator device to cause only one of the two calipers present in the system to act up to a certain threshold value.
Claims8
A double caliper braking system consisting essentially of a disc supported by a hub and rotatable within first and second brake calipers connected to a pressure circuit and fixed to said hub, characterized in that said first brake caliper is of smaller dimensions than said second caliper, said first caliper acting under a pressure in said circuit which is less than the pressure under which said second caliper acts whereby a pressure subtraction device is adapted to cause said first caliper to act within a predetermined pressure range, said pressure circuit consists of two branches each of which is connected to one of said calipers, said branches being connected in parallel.
A double caliper braking system comprising:
- a first brake caliper;
- a second brake caliper having larger dimensions than said first brake caliper and acting under a pressure which is greater than the pressure under which the first caliper acts;
- a disc supported by a hub and rotatable within said first and second calipers;
- a pressure circuit having a supply branch dividing into first and second parallel branches, said first parallel branch supplying pressure to said first caliper, said second parallel branch supplying said second caliper;
- a pressure subtraction device adapted to cause said first caliper to act within a predetermined pressure range;
- whereby
- when the pressure supplied to said first caliper exceeds said predetermined range, said second caliper is activated.
