Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
164 words
Equalization installation for the chassis of motor vehicles, comprising electronic computer means operatively connected with servo-control means arranged at least at one of the two parts consisting of chassis and body of the vehicle, said servo-control means being controlled by signals transmitted from the computer means, and detecting means forming transmitter means for detecting at least one of the movements and force changes of at least one of the two parts consisting of chassis and body, said detecting means being operatively connected with said computer means for feeding the signals detected by said detecting means to said computer means, said computer means being responsive to the signals of said detecting means for processing the signals and for transmitting output signals to the servo-control means to effect an equalization of the chassis, said detecting means including accelereation responsive means for detecting and feeding signals indicative of the positioning of one of the parts consisting of chassis and body to said computer means for processing thereby.
Claim 2
Dependent Claim
164 words
Equalization installation for the chassis of motor vehicles, comprising electronic computer means operatively connected with servo-control means arranged at least at one of the two parts consisting of chassis and body of the vehicle, said servo-control means being controlled by signals transmitted from the computer means, and detecting means forming transmitter means for detecting at least one of the movements and force changes of at least one of the two parts consisting of chassis and body, said detecting means being operatively connected with said computer means for feeding the signals detected by said detecting means to said computer means, said computer means being responsive to the signals of said detecting means for processing the signals and for transmitting output signals to the servo-control means to effect an equalization of the chassis, said detecting means including accelereation responsive means for detecting and feeding signals indicative of the positioning of one of the parts consisting of chassis and body to said computer means for processing thereby.
Claim 3
Dependent Claim
16 words
An equalization installation according to claim 1, wherein said acceleration responsive means is a gyroscope means.
Claim 4
Dependent Claim
26 words
An equalization installation according to claim 2, wherein said computer means is an analog computer means and said gyroscope means is mounted within said computer means.
Claim 5
Dependent Claim
41 words
An equalization installation according to claim 1, wherein said servo-control means includes a hydraulic switch means arranged between spring leg means and pressure tank means of a hydropneumatic spring means, said hydraulic switch means being electrically actuatable by said computer means.
Claim 6
Dependent Claim
29 words
An equalization installation according to claim 1, wherein said servo-control means includes servo pressure equalizing means operatively connected to hydropneumatic spring means arranged at the wheels of the vehicle.
Claim 7
Dependent Claim
35 words
An equalization installation according to claim 5, wherein said servo pressure equalizing means includes displacement pick-up means responsive to said computer means for controlling the movement of a servopiston of said servo pressure equalizing means.
Claim 8
Dependent Claim
20 words
An equalization installation according to claim 1, wherein said detecting means includes transmitter means connected with the spring leg means.
Claim 9
Dependent Claim
22 words
An equalization installation according to claim 1, wherein said computer means is a central electronic computer means provided for all control operations.
Claim 10
Dependent Claim
33 words
An equalization installation according to claim 1, further comprising separate electronic control circuit means, each control circuit means having a computer means for relatively more simple control operations dependent essentailly from one component.
Claim 11
Dependent Claim
24 words
An equalization installation according to claim 9, wherein said control operations include compensation for starting nose-diving and erection of the body against centrifugal force.
