Abstract
Abstract A novel suspension system for a cab of a motor vehicle is provided herein. The suspension is adapted to be used with a cab which is springingly-supported by shock absorbers. The suspension includes a longitudinally-extending sub-frame disposed between the cab and a main frame of the vehicle. The sub-frame includes transverse means connecting two longitudinally-extending lateral sub-frame members with fluid-actuated levelling means disposed between the transverse means and the support for such cab. Means are provided for controlling the ingress of fluid to, and the egress of fluid from, the fluid-actuated levelling means. Means are interposed between the lateral means and the cab support means for actuating the controlling means of the vehicle. In this way, the cab is maintained at a constant vertical level regardless of the vertical vibrations to which the cab may be subjected.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
103 words
A support for a cab for a truck comprising: a plurality of cross-beams supported between the longitudinal frame members of a vehicle; means connected between each lateral frame member and respective lateral edge of a transverse platform supporting the cab, said means including damping means; pneumatic means disposed between said cross-beams and said transverse platform and situ-ated inboard of said frame members; stabilizer valve means for supplying air to, and withdrawing air from, said pneumatic means and control means adapted to sense the vertical position of said platform and actuatable to maintain the elevation of said platform within preset upper and lower positions.
Claim 2
Dependent Claim
103 words
A support for a cab for a truck comprising: a plurality of cross-beams supported between the longitudinal frame members of a vehicle; means connected between each lateral frame member and respective lateral edge of a transverse platform supporting the cab, said means including damping means; pneumatic means disposed between said cross-beams and said transverse platform and situ-ated inboard of said frame members; stabilizer valve means for supplying air to, and withdrawing air from, said pneumatic means and control means adapted to sense the vertical position of said platform and actuatable to maintain the elevation of said platform within preset upper and lower positions.
Claim 3
Dependent Claim
96 words
A suspension for a cab of a vehicle, said cab being spring-ingly-supported by shock absorbers, said suspension including a longitudinally-extending sub-frame disposed between said cab and a main frame of said vehicle, said sub-frame including: (a) transverse means connecting two longitudinally-extend-ing lateral sub-frame members; (b) fluid-actuated levelling means disposed between said transverse means and said support for such cab; (c) means for controlling the ingress and the egress of fluid to, and from, said fluid-actuated levelling means; and (d) means interposed between said lateral sub-frame members and said cab support means for actuating said controll-ing means.
Claim 4
Dependent Claim
96 words
A suspension for a cab of a vehicle, said cab being spring-ingly-supported by shock absorbers, said suspension including a longitudinally-extending sub-frame disposed between said cab and a main frame of said vehicle, said sub-frame including: (a) transverse means connecting two longitudinally-extend-ing lateral sub-frame members; (b) fluid-actuated levelling means disposed between said transverse means and said support for such cab; (c) means for controlling the ingress and the egress of fluid to, and from, said fluid-actuated levelling means; and (d) means interposed between said lateral sub-frame members and said cab support means for actuating said controll-ing means.
Claim 5
Dependent Claim
47 words
The suspension of claim 2 wherein said cab is supported on a platform, said platform extending longitudinally between at least two longitudinally-spaced-apart, transversely-extending frame members, said frame members supporting hydraulic shock absorbers laterally-disposed between said transverse frame members and the main longitudinally-extending frame members of said vehicle.
Claim 6
Dependent Claim
47 words
The suspension of claim 3 wherein each of said hydraulic shock absorber is mounted with its rod end connected to a depend-ing ear of said transversely-extending frame member and with its rod end connected to a laterally-extending ear of said longitudi-nally-extending main frame member of said vehicle.
Claim 7
Dependent Claim
13 words
The suspension of claim 2 wherein said fluid-actuated levelling means comprise pneumatic balloons.
Claim 8
Dependent Claim
14 words
The suspension of claim 5 wherein said controlling means comprises a pneumatic stabilizer valve.
Claim 9
Dependent Claim
23 words
The suspension of claim 6 wherein said interposed means comprises a vertically-movable rod, whose lower end is operative-ly-connected to a three-way pneumatic valve.
