  • Patent number: 4832363
    Abstract: An independent rear wheel suspension (100; 100') for a vehicle in which a knuckle (1) rotatably supporting a rear wheel (2) of the vehicle is pivotably connected in a vertically movable manner to the vehicle body by means of a substantially longitudinally extending trailing arm (5), a substantially transversely extending upper arm (3), a substantially transversely extending short front lower arm (6), and a substantially transversely extending long rear lower arm (4). The knuckle (1) is vertically swingingly pivotably attached to the upper arm (3) and the rear lower arm (4). The upper arm (3), trailing arm (5), front lower arm (6), and rear lower arm (4) are vertically swingingly pivotably attached to the vehicle body. The knuckle (1) is leftwardly and rightwardly swingingly pivotably attached to the trailing arm (5) so as to rotate about a substantially vertical axis (12-14) extending through the rear end part (A) of the trailing arm (5).

  • Patent number: 4740011
    Abstract: A suspension for a motor vehicle has a link structure and a spring interposed between the link structure and a vehicle frame. The link structure comprises a trailing arm extending substantially longitudinally of the vehicle frame and having a front end pivotally coupled to the vehicle frame and a rear end supporting a wheel, upper and lower arms extending substantially transversely of the vehicle frame and each having one end pivotally coupled to the vehicle frame and an opposite end pivotally coupled to the trailing arm in the vicinity of a rear end thereof, and a compensation link having one end pivotally coupled to the vehicle frame and an opposite end pivotally coupled to the trailing arm. The suspension is relatively lightweight, inexpensive to construct, and has excellent performance.
