Abstract
Abstract Apparatus for cancelling out and/or suppressing the spring action between the wheel mounts and frame of a vehicle and means for manually setting the apparatus in an operative or nonoperative condition as desired. This apparatus entails a strut bar between each wheel mount and the chassis of the vehicle and means on the chassis embracing each such struct bar for grippingly engaging the strut bar to prevent its motion relative to the chassis whereby the wheel mounts become affixed relative to the frame and chassis of the vehicle. The means for grippingly engaging each strut bar includes a caliper type braking clamp for each of such bars and an hydraulic brake actuating system for operating such braking clamps. This may include a bypass line from the conventional hydraulic braking system of the vehicle and means for locking such bypass line in brake actuating condition.

Claims Analysis
Total Claims: 33
Claim 1
Independent Claim
152 words
In combination with a spring mount for a wheel which is normally articulatable relative to the frame of a vehicle and an hydraulic braking system of such vehicle, a spring suppressor comprising: 1. a housing secured to the frame of such vehicle and having a passage formed therethrough; 2. a strut member having one end pivotally connected to such spring mount and its opposite end arranged for free sliding movement through the passage through said housing during normal articulation of the spring mount; 3. an hydraulically operated caliper type brake in said housing including a pair of brake shoes embracing said strut therein; and 4. an hydraulic brake operating system in said vehicle communicating with said hydraulically operated caliper type brake for urging the brake shoes thereof into gripping engagement with said strut to thereby render the spring mounts of the vehicle in fixed relation relative to the frame of the vehicle.
Claim 2
Dependent Claim
152 words
In combination with a spring mount for a wheel which is normally articulatable relative to the frame of a vehicle and an hydraulic braking system of such vehicle, a spring suppressor comprising: 1. a housing secured to the frame of such vehicle and having a passage formed therethrough; 2. a strut member having one end pivotally connected to such spring mount and its opposite end arranged for free sliding movement through the passage through said housing during normal articulation of the spring mount; 3. an hydraulically operated caliper type brake in said housing including a pair of brake shoes embracing said strut therein; and 4. an hydraulic brake operating system in said vehicle communicating with said hydraulically operated caliper type brake for urging the brake shoes thereof into gripping engagement with said strut to thereby render the spring mounts of the vehicle in fixed relation relative to the frame of the vehicle.
Claim 3
Dependent Claim
79 words
The spring suppressor in accordance with that of claim 1 including a bypass conduit means communicating the hydraulic braking system of such vehicle with said hydraulically operated caliper type brake within said housing for urging the brake shoes within the latter into gripping engagement with said strut during normal braking operation of the hydraulic braking system of the vehicle to thereby render the spring mounts of the vehicle in fixed, non-articulatable relation relative to the frame of the vehicle.
Claim 4
Dependent Claim
34 words
a strut member having one end pivotally connected to such spring mount and its opposite end arranged for free sliding movement through the passage through said housing during normal articulation of the spring mount;
