Abstract
Abstract A vehicle rear suspension system having a vertically swingable arm connected at the front end swingably to the vehicle body and secured at the rear end to a wheel carrying member which carries a rear wheel for rotation. Three lateral links are provided and have inward ends pivotably connected to the vehicle body and outward ends pivotably connected to the wheel carrying member. The points of connection of the three lateral links to the wheel carrying member are not aligned in a straight line so that the orientations of the wheel carrying member can appropriately be controlled under a bump and rebouncing movements of the rear wheel and under a side and longitudinal forces acting on the rear wheel.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
166 words
A vehicle rear suspension system comprising swing arm means extending substantially longitudinally and having one end connected to a vehicile body for vertical swinging movements, wheel carrying means for carrying a rear wheel for rotation about a rotation axis, said wheel carrying means being connected with said swing arm means at the other end of the swing arm means so that a longitudinal force and a rotating force about a transverse axis extending in a lateral direction of the vehicle body can be transmitted between the swing arm means and the wheel carrying means, first, second and third lateral link means extending in substantially lateral direction of the vehicle body, each of said lateral link means having one end pivotably connected with said wheel carrying means and the other end pivotably connected with the vehicle body, said one ends of the first, second and third lateral link means being connected to said wheel carrying means at locations which are not aligned on a single straight line.
Claim 2
Dependent Claim
166 words
A vehicle rear suspension system comprising swing arm means extending substantially longitudinally and having one end connected to a vehicile body for vertical swinging movements, wheel carrying means for carrying a rear wheel for rotation about a rotation axis, said wheel carrying means being connected with said swing arm means at the other end of the swing arm means so that a longitudinal force and a rotating force about a transverse axis extending in a lateral direction of the vehicle body can be transmitted between the swing arm means and the wheel carrying means, first, second and third lateral link means extending in substantially lateral direction of the vehicle body, each of said lateral link means having one end pivotably connected with said wheel carrying means and the other end pivotably connected with the vehicle body, said one ends of the first, second and third lateral link means being connected to said wheel carrying means at locations which are not aligned on a single straight line.
Claim 3
Dependent Claim
32 words
A vehicle rear suspension system in accordance with claim 1 in which said one end of the swing arm means is a front end and said other end is a rear end.
Claim 4
Dependent Claim
33 words
A vehicle rear suspension system in accordance with claim 1 in which said swing arm means includes means for permitting lateral displacement of said wheel carrying means with respect to the vehicle body.
Claim 5
Dependent Claim
63 words
A vehicle rear suspension system in accordance with claim 1 in which said one end of the swing arm means is connected to the vehicle body through rubber bush means having an axis arranged in substantially lateral direction of the vehicle body so as to permit lateral displacement of said swing arm means to thereby permit lateral displacement of the wheel carrying means.
Claim 6
Dependent Claim
49 words
A vehicle rear suspension system in accordance with claim 1 in which said swing arm means has a cross- section which provides a low rigidity in the lateral direction so as to permit lateral deflection of the swing arm means thereby permitting lateral displacement of the wheel carrying means.
Claim 7
Dependent Claim
79 words
A vehicle rear suspension system in accordance with claim 1 in which one of the lateral link means is connected to the wheel carrying means at a position higher than positions where the other two lateral link means are connected with the wheel carrying means, the said positions being so located that a cornering force acting point on the rear wheel is between imaginary lines passing through the first mentioned position and respective ones of the second mentioned positions.
Claim 8
Dependent Claim
37 words
A vehicle rear suspension system in accordance with claim 6 in which the first mentioned position is located above the rotation axis of the rear wheel and the second mentioned positions are located below the rotation axis.
Claim 9
Dependent Claim
81 words
A vehicle rear suspension system in accordance with claim 6 in which the second lateral link means is connected to the wheel carrying means at a position above the rotation axis of the rear wheel, the first lateral link means being connected at a position below and forward the rotation axis and the third lateral link means being connected at a position below and rearward the rotation axis, the first lateral link means being shorter than the third lateral link means.
Claim 10
Dependent Claim
37 words
A vehicle rear suspension system in accordance with claim 7 in which said other two link means have axes which intersect each other in a projection on a horizontal plane at a point outward the rear wheel.
Claim 11
Dependent Claim
63 words
A vehicle rear suspension system in accordance with claim 6 in which forward one of said other two lateral link means being apart from a line passing through the first mentioned position and said cornering force acting point by a distance which is smaller than a distance by which rearward one of said other two lateral link means is apart from said line.
Claim 12
Dependent Claim
68 words
A vehicle rear suspension system in accordance with claim 10 in which the second lateral link means is connected to the wheel carrying means at a position above the rotation axis of the rear wheel, the first lateral link means being connected at a position below and forward the rotation axis and the third lateral link means being connected at a position below and rearward the rotation axis.
Claim 13
Dependent Claim
79 words
A vehicle rear suspension system in accordance with claim 1 in which said second and third link means are arranged rearward the first link means, the second link means being above and shorter than the third lateral link means, projections in a vertical transverse plane of longitudinal axes of the second and third lateral link means intersecting each other at a point inward the rear wheel, the first link means being shorter than the second and third link means.
Claim 14
Dependent Claim
173 words
A vehicle rear suspension system comprising swing arm means extending substantially longitudinally and having one end connected to a vehicle body for vertical swinging movements, wheel carrying means for carrying a rear wheel for rotation about a rotation axis, said wheel carrying means being connected with said swing arm means at the other end of the swing arm means so that a longitudinal force and a rotating force about a lateral axis can be transmitted between the swing arm means and the wheel carrying means, first, second and third lateral link means extending in substantially lateral direction of the vehicle body and having one ends pivotably connected with the vehicle body, the other ends of said first, second and third lateral link means being connected to the wheel carrying means at positions, respectively, below and forward, above and forward, and below and rearward the wheel rotation axis, said first and third lateral link means having axes intersecting each other in a projection on a horizontal plane at a position outward the rear wheel.
Claim 15
Dependent Claim
173 words
