Abstract
A trailing arm construction for the rear wheels of an automotive vehicle including a trailing arm, a pivotal mounting for the fore portion of the trailing arm, a shear rubber spring mounted directly between the vehicle frame and a central portion of the trailing arm, a bracket for attaching the driven vehicle axle to the central portion of the trailing arm, and a coil spring mounted directly between the aft portion of the trailing arm and the vehicle frame. A construction as described including a tag arm construction for mounting a wheel behind the rear wheels including a tag arm having a fore portion pivotally mounted directly on the vehicle frame, a bracket on the central portion of the tag arm for mounting an axle, and a shear rubber spring mounted directly between the vehicle frame and the aft portion of the tag arm.
Claims19
In a vehicle having a frame including a frame portion which extends longitudinally of said vehicle and an axle positioned under the frame, a trailing arm axle suspension comprising an elongated trailing arm having fore and aft and central portions extending longitudinally of said vehicle, first means for pivotally mounting said fore portion directly on and laterally offset from said frame portion, shear rubber spring means, second means for mounting said shear rubber spring means directly between and laterally offset from both said central portion of said trailing arm and said frame portion, third means for securing said axle to said central portion of said trailing arm, spring means, and fourth means for securing said spring means directly between said frame portion and said aft portion of said trailing arm.
In a vehicle having a frame including a frame portion which extends longitudinally of said vehicle and an axle positioned under the frame, a trailing arm axle suspension comprising an elongated trailing arm having fore and aft and central portions extending longitudinally of said vehicle, spacer means laterally offset from said frame portion, first means for pivotally mounting said fore portion directly on said frame portion and laterally offset therefrom with said spacer means therebetween, shear rubber spring means having a thickness which is substantially equal to the width of said spacer means, second means for mounting said shear rubber spring means laterally of and directly between both said central portion of said trailing arm and said frame portion, third means for securing said axle to said central portion of said elongated trailing arm, spring means, and fourth means for securing said spring means between said frame portion and said aft portion of said trailing arm.
In a vehicle having a frame including first and second spaced frame portions which extend longitudinally of said vehicle and an axle positioned under the frame, a trailing arm axle suspension comprising first and second spaced elongated trailing arms each having fore and aft and central portions extending longitudinally of said vehicle, first means for pivotally mounting said fore portions of said first and second trailing arms directly on said first and second frame portions, respectively, and laterally offset therefrom, first and second shear rubber spring means, second means for mounting said first and second shear rubber spring means directly between and laterally offset from said central portions of said first and second trailing arms, respectively, and said first and second frame portions, respectively, third means for securing said axle to said central portions of said first and second trailing arms, first and second spring means, and fourth means for securing said first and second spring means directly between said first and second frame portions, respectively, and said aft portions of said first and second trailing arms, respectively.
In a vehicle having a frame including a frame portion which extends longitudinally of said vehicle and an axle positioned under the frame, a trailing arm axle suspension comprising an elongated trailing arm having fore and aft and central portions extending longitudinally of said vehicle, first means for pivotally mounting said fore portion directly on said frame portion, shear rubber spring means, second means for mounting said shear rubber spring means directly between said central portion of said trailing arm and said frame portion, third means for securing said axle to said central portion of said trailing arm, coil spring means, fourth means for securing said coil spring means directly between said frame portion and said aft portion of said trailing arm, said shear rubber spring means being located between said axle and said first means, said frame including a second frame portion which extends transversely to said frame portion, and track bar means effectively coupled between said second frame portion and said trailing arm.
In a vehicle having a frame including a frame portion which extends longitudinally of said vehicle and an axle positioned under the frame, a trailing arm axle suspension comprising an elongated trailing arm having fore and aft and central portions extending longitudinally of said vehicle, first means for pivotally mounting said fore portion directly on said frame portion, shear rubber spring means, second means for mounting said shear rubber spring means directly between said central portion of said trailing arm and said frame portion, third means for securing said axle to said central portion of said trailing arm, coil spring means, fourth means for securing said coil spring means directly between said frame portion and said aft portion of said trailing arm, said shear rubber spring means being located between said axle and said first means, said first means comprising a bracket plate, means connecting said bracket plate to said frame portion, a shaft extending outwardly from said bracket plate, first and second ends on said shaft, means fixedly securing said first end to said bracket plate, a rubber bushing mounted on said shaft, clamp means on said first end of said trailing arm securing said trailing arm on said rubber bushing, and confining plate means secured to said second end of said shaft to confine said rubber bushing and said clamp means against axial movement off of said second end of said shaft.
In a vehicle having a frame including a frame portion which extends longitudinally of said vehicle and an axle positioned under the frame, a trailing arm axle suspension comprising an elongated trailing arm having fore and aft and central portions extending longitudinally of said vehicle, first means for pivotally mounting said fore portion directly on said frame portion, shear rubber spring means, second means for mounting said shear rubber spring means directly between said central portion of said trailing arm and said frame portion, third means for securing said axle to said central portion of said trailing arm, coil spring means, fourth means for securing said coil spring means directly between said frame portion and said aft portion of said trailing arm, a trailing tag arm having a tag arm fore portion and a tag arm central portion and a tag arm aft portion, said trailing tag arm being mounted aft of said trailing arm, fifth means pivotally mounting said tag arm fore portion proximate said fourth means, sixth means securing a second axle on said tag arm central portion, second shear rubber spring means, and seventh means securing said second shear rubber spring means directly between said frame portion and said tag arm aft portion.
