Abstract

Abstract The vehicle suspension is a so-called independent wheel suspension, each wheel being journalled on a stub axle fixed to the free end of a straight arm extending lengthwise of the line of travel and the other end of which is fixed to a transverse hub member journalled in spaced frame bearings. Substantially the entire resilient support for the frame on its arms is in the form of at least one rectilinear upright movement shear rubber body above each arm inwardly of the corresponding wheel and having opposite generally upright parallel exterior working faces. A plate bonded to one working face connects with the frame and a plate bonded to the other working face connects with the corresponding arm. Desirably the shear rubber bodies are arranged as low and close to the arms as possible to reduce stress thereon; their connection with each arm includes a flexible rubber pad which distorts horizontally to compensate for the changes in effective length of the arms; the shear rubber body working faces are crosswise of the line of vehicle travel; and telescopic shock absorbers are severally between the free ends of their arms and frame brackets which also connect the other parts of the suspension to the frame.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 329 words
A vehicle spring suspension adapted to be interposed between each side of a vehicle frame member and a rubber tired supporting wheel having a road engaging tread, wherein the improvment comprises a generally horizontal hub structure for each suspension arranged under the corresponding side of the frame member and generally parallel with the axis of rotation of its wheel, each hub structure having an inboard end extending toward the vertical center plane of the vehicle frame member and an outboard end projecting outwardly from under said frame member, a relatively straight arm member having one end arranged below the space between each wheel means providing the corresponding side of said frame member and fixed to said outboard end of the corresponding hub structure to project radially therefrom toward said axis of rotation of said wheel, a stub axle projecting horizontally outwardly laterally from the other end of each arm member along said axis of rotation of and journalled on its wheel, an inboard frame bearing connecting said inboard end of each hub structure to the frame member, an outboard frame bearing connecting the outboard end of each hub structure to the frame member, and meanproviding resilient support for the frame member on each of said arm members, comprising at least one rectilinear upright movement shear rubber body arranged above each arm member inwardly of the corresponding wheel and having on its opposite sides generally upright parallel working faces, a bracket fixed to one of said members at each side of said frame member and bonded to one of said working faces of the corresponding shear rubber body, and means operatively connecting the other of said working faces of each shear rubber body to the other of said members, including a rubber pad which is flexed lengthwise of the line of vehicle travel in response to the effective lengthening and shortening of said arm member, lengthwise of the line of vehicle travel, as it swings vertically in its said bearings.
Claim 2
Dependent Claim 329 words
A vehicle spring suspension adapted to be interposed between each side of a vehicle frame member and a rubber tired supporting wheel having a road engaging tread, wherein the improvment comprises a generally horizontal hub structure for each suspension arranged under the corresponding side of the frame member and generally parallel with the axis of rotation of its wheel, each hub structure having an inboard end extending toward the vertical center plane of the vehicle frame member and an outboard end projecting outwardly from under said frame member, a relatively straight arm member having one end arranged below the space between each wheel means providing the corresponding side of said frame member and fixed to said outboard end of the corresponding hub structure to project radially therefrom toward said axis of rotation of said wheel, a stub axle projecting horizontally outwardly laterally from the other end of each arm member along said axis of rotation of and journalled on its wheel, an inboard frame bearing connecting said inboard end of each hub structure to the frame member, an outboard frame bearing connecting the outboard end of each hub structure to the frame member, and meanproviding resilient support for the frame member on each of said arm members, comprising at least one rectilinear upright movement shear rubber body arranged above each arm member inwardly of the corresponding wheel and having on its opposite sides generally upright parallel working faces, a bracket fixed to one of said members at each side of said frame member and bonded to one of said working faces of the corresponding shear rubber body, and means operatively connecting the other of said working faces of each shear rubber body to the other of said members, including a rubber pad which is flexed lengthwise of the line of vehicle travel in response to the effective lengthening and shortening of said arm member, lengthwise of the line of vehicle travel, as it swings vertically in its said bearings.
Claim 3
Dependent Claim 84 words
A vehicle spring suspension as set forth in claim 1 having a pair of such rectilinear movement shear rubbEr bodies arranged above each arm member, and wherein said means operatively connecting the other of said working faces of each shear rubber body to the other of said members includes metal plate means bonded to the opposing working faces of each pair of said shear rubber bodies, said rubber pad being operatively interposed between each metal plate means and the corresponding other of said members.
Claim 4
Dependent Claim 47 words
A vehicle spring suspension as set forth in claim 2 wherein each of said one of said members to which the corresponding bracket is fixed, is said frame member, and wherein each rubber pad is operatively interposed between each metal plate means and the corresponding arm member.
