Abstract
Abstract A vehicle includes a spaced apart sprung and unsprung portion with suspension and vertical dampening connected therebetween. A first pair of link members are pivotly attached to the sprung portion in a laterally spaced apart relationship and second pair of link members are pivotly connected to the unsprung portion. Each link of the first pair of link members is pivotly connected to one link of the second pair of link members at their ends opposite their respective sprung and unsprung portion attachment by a common link pin. A rod is fixedly attached at each of its ends to one of the link pins and is substantially parallel with said sprung and unsprung portions. The first link members are parallel and the second link members are parallel and equal angles are formed between the first and second links at their joinders.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
233 words
Improved lateral stabilizing apparatus for a surface supported vehicle having a sprung frame and body portion attached thereto and an unsprung wheel and axle surface contacting portions comprising: an upper support bar attached to said frame transversely thereof, a lower support bar attached to said axle parallel to said first bar, suspension and vertical dampening means connected between said sprung and unsprung portions, two upper pairs of links connected to the upper bar, the pairs being spaced along the bar, the links of each pair being parallel and pivotally connected to the respective forward and rearward sides of the bar, two lower pairs of links connected to the lower bar, the lower pairs being spaced along the lower bar, the links of each lower pair being parallel and pivotally connected to the respective forward and rearward sides of the lower bar, a pivot pin connected between the parallel links of each pair of one of the upper and lower pairs, a resilient bushing surrounding each of said pivot pins and extending between the links connected thereby, a rigid bushing about each of said resilient bushing, said resilient bushing being pivotally mounted in openings in the parallel links of the other of the upper and lower pairs respectively, and a rigid member securing the rigid bushings together, the pivotally connected upper and lower links of all the pairs forming equal included angles between them.
