Abstract

Abstract A wheel suspension for a motor vehicle having a vehicle chassis comprises a wheel carrier having a journal for the support of a wheel for rotation independently of the wheel carrier, and first and second arms for supporting the wheel carrier to the vehicle chassis and extending in spaced relation to each other with the space therebetween gradually increasing as they extend outwardly from the wheel carrier towards the vehicle chassis. The wheel suspension further comprises a connecting member for elastically connecting the wheel carrier to the vehicle chassis for the displacement in a direction generally perpendicular to the widthwise direction of the vehicle chassis, and a shock absorber for absorbing vibration of the wheel carrier. The journal extends outwardly from the wheel carrier at a position spaced a smaller distance from the joint of the first arm to the wheel carrier than from the joint of the second arm to the wheel carrier.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 278 words
In a wheel suspension for a vehicle having a vehicle chassis, which comprises a wheel support including a wheel carrier, said wheel carrier having a wheel journal for the support of a wheel for rotation independently of the wheel carrier, front and rear arm members extending between the wheel carrier and the vehicle chassis in spaced relation to each other in a direction generally laterally of the vehicle chassis, the front arm member having a first end hingedly and yieldingly connected to a front portion of the wheel carrier and a second end hingedly and yieldingly connected to a front lateral portion of the vehicle chassis and the rear arm member has a first end hingedly and yieldingly connected to a rear portion of the wheel carrier and a second end hingedly and yieldingly connected to a rear lateral portion of the vehicle chassis, a connecting member for elastically connecting the wheel support to the vehicle chassis for displacement in a direction generally perpendicular to the widthwise direction of the vehicle chassis, and a shock absorber means for absorbing vibrations of the wheel carrier which take place in a direction at right angles to the road surface during the running of the vehicle, the improvement wherein said journal extends outwardly from the wheel carrier in a direction opposite to any one of the front and rear arm members at a position spaced a smaller distance from the joint of the first end of the front arm member to the front portion of the wheel carrier than the distance from the joint of the first end of the rear arm member to the rear portion of the wheel carrier.
Claim 2
Dependent Claim 278 words
In a wheel suspension for a vehicle having a vehicle chassis, which comprises a wheel support including a wheel carrier, said wheel carrier having a wheel journal for the support of a wheel for rotation independently of the wheel carrier, front and rear arm members extending between the wheel carrier and the vehicle chassis in spaced relation to each other in a direction generally laterally of the vehicle chassis, the front arm member having a first end hingedly and yieldingly connected to a front portion of the wheel carrier and a second end hingedly and yieldingly connected to a front lateral portion of the vehicle chassis and the rear arm member has a first end hingedly and yieldingly connected to a rear portion of the wheel carrier and a second end hingedly and yieldingly connected to a rear lateral portion of the vehicle chassis, a connecting member for elastically connecting the wheel support to the vehicle chassis for displacement in a direction generally perpendicular to the widthwise direction of the vehicle chassis, and a shock absorber means for absorbing vibrations of the wheel carrier which take place in a direction at right angles to the road surface during the running of the vehicle, the improvement wherein said journal extends outwardly from the wheel carrier in a direction opposite to any one of the front and rear arm members at a position spaced a smaller distance from the joint of the first end of the front arm member to the front portion of the wheel carrier than the distance from the joint of the first end of the rear arm member to the rear portion of the wheel carrier.
Claim 3
Dependent Claim 47 words
A wheel suspension as claimed in claim 1, wherein said connecting member comprises a tension rod having one end adjacent the wheel support hingedly and yieldingly connected to the wheel carrier and the other end hingedly and yieldingly connected to a front portion of the vehicle chassis.
Claim 4
Dependent Claim 26 words
A wheel suspension as claimed in claim 1, wherein said shock absorber is positioned between the wheel carrier and an overhanging portion of the vehicle chassis.
