Abstract: A sealing device has a single rubber seal member provided with two oppositely directed seal lips which form a V-shaped cross-section and which are in contact with a spherical surface. Grease is filled in the V-shaped space. A portion of an outer fitting member protrudes inwardly to hold the seal member in place.

Abstract: An assembly maintenance tube maintains a live spindle mounted within a bore of a vehicle mounting component. The maintenance tube has a central aperture for receiving in a spaced relationship a drivable axle. The axle is drivingly connected to the live spindle in a manner which allows axial movement of the axle relative to the spindle to relieve stress in the drive train which drives the axle.

Abstract: In this device, which is particularly, but not exclusively, suitable for transmissions for vehicles, an elastomer protecting gaiter comprises a body connected by a fold to a mounting flange and by another fold to a neck portion. The latter comprises a ring forming a bearing, an arrangement for mounting the neck portion in a support, and a sealing device. The body of the gaiter is preferably rigid.

Abstract: The homokinetic transmission device is placed between a driving shaft and a driven shaft comprising two adjacent articulated joints. The articulated joints comprise a common intermediate member and are generally homokinetic and at least one of the joints is slidable. The arrangement of the two joints is adapted to permit a relative radial displacement between the two shafts. If h and l are the respective distances between the centers of the two adjacent tripod joints and the center of gravity of the transmission device interconnecting the two shafts, and .rho..sup.2 and Io/m, where Io represents the inertia of an intermediate member about an axis perpendicular to its general axis and to the direction of lateral displacement of said member and intersecting the center of gravity G, and where m represents the mass of the intermediate member, the following conditions are at least roughly satisfied:h.times.l=.rho..sup.2.

Abstract: An independent suspension system in which a steering knuckle is employed with an upper ball joint connection to an upper control arm and a lower ball joint connection to an axle outer end.

Abstract: Front wheel suspension for electric vehicles with front wheel drive, comprisingat least two arms provided between a rigid front axle and frame members of the vehicle, at least one of said arms being articulated to the axle and all arms extending mainly horizontally from the axle and being connected to the frame members by means of ball joints,a differential unit arranged at the central part of the axle between the arms,an electromotor mounted directly on the differential unit and extending away from the axle mainly horizontally and in the same direction as the arms so that the center of gravity of the motor is all the time lying substantially stationary on a line through said ball joints, andsprings in the form of helical springs or rubber springs provided between the axle and the frame members.
