Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
137 words
A slip-controlled brake system for automotive vehicles having one static brake circuit into which pressure fluid from a dynamic pressure fluid circuit can be introduced when a control action is performed, said system comprising a master cylinder assembly and a hydraulic booster (11), a hydraulic auxiliary-pressure supply system, wheel sensors and electronic circuits for determining the wheel rotational behavior and for generating electric braking-pressure control signals which serve to control pressure-fluid inlet valves and outlet valves inserted into the pressure fluid lines for the purpose of slip control, and a vacuum booster (1) connected upstream of said hydraulic booster (11), said vacuum booster (1) having a force-output member (51) which is in operative engagement with an articulated lever apparatus (41), whereby said vacuum booster (1) acts directly to generate braking pressure upon failure of said hydraulic booster.
Claim 2
Dependent Claim
137 words
A slip-controlled brake system for automotive vehicles having one static brake circuit into which pressure fluid from a dynamic pressure fluid circuit can be introduced when a control action is performed, said system comprising a master cylinder assembly and a hydraulic booster (11), a hydraulic auxiliary-pressure supply system, wheel sensors and electronic circuits for determining the wheel rotational behavior and for generating electric braking-pressure control signals which serve to control pressure-fluid inlet valves and outlet valves inserted into the pressure fluid lines for the purpose of slip control, and a vacuum booster (1) connected upstream of said hydraulic booster (11), said vacuum booster (1) having a force-output member (51) which is in operative engagement with an articulated lever apparatus (41), whereby said vacuum booster (1) acts directly to generate braking pressure upon failure of said hydraulic booster.
Claim 3
Dependent Claim
41 words
A slip-controlled brake system as claimed in claim 1, wherein the force-output member (51) of the vacuum booster (1) is articulated at the coupling element for the valve piston (20), and at the control piston (53) of the booster piston (54).
Claim 4
Dependent Claim
48 words
A slip-controlled brake system as claimed in claim 1, wherein said force-output member (51) is supported at its end closest to said master cylinder assembly on said booster piston (54) of said hydraulic booster (11) through a control piston (53) by means of an intermediary resilient element (56).
Claim 5
Dependent Claim
41 words
The slip-controlled brake system as claimed in claim 1, wherein said articulated lever apparatus (41) is in operative engagement with a valve piston (20) to control the degree of fluid pressure in the booster chamber (21) of the hydraulic booster (11).
Claim 6
Dependent Claim
35 words
The slip-controlled brake system as claimed in claim 4, wherein said force-output member of said vacuum booster is held and guided in a longitudinal bore of the booster piston (54) of the hydraulic booster (11).
Claim 7
Dependent Claim
46 words
The slip-controlled brake system as claimed in claim 5, wherein said booster chamber (21) of said hydraulic booster (11) communicates by means of a pressure line (14) with one or more wheel brakes and forms a dynamic brake circuit by means of said pressure line (14).
