Abstract:
A protective strip for motor vehicles, especially for passenger motor vehicles, which includes an elastic profile adapted to be inserted into a recess or indentation provided at the vehicle body covering; the elastic profile is provided on its side facing the vehicle body covering with a longitudinal slot into which is inserted a retaining profile which is provided with fastening elements engaging in bores of the vehicle body covering to thereby pull the elastic profile into the recess or indentation of the vehicle body covering when assembled.
Abstract:
An installation for increasing the ground traction in a vehicle, especially in a passenger motor vehicle below which a vacuum is adapted to be produced by suction for the removal of air at least within a partial area that is defined by a shielding device that can be selectively shifted from its rest position remote from the ground into a use position near the ground and which is provided between the vehicle and the road surface; the shielding device is thereby constituted by an annular cushion surrounding the partial area to be subjected to vacuum whereby the annular cushion is suitably connected with the vehicle superstructure.
Abstract:
A wheel suspension for the oppositely disposed wheels of an axle of a motor vehicle which includes an upper and a lower guide means for each wheel carrier thereof, whereby, for example, the lower guide means are constituted by mutually independent guide members and the upper guide means are constituted by a cross connection and by guide members in the form of a triangular guide members coupled with each other by the cross connection; during unidirectional spring movements of the oppositely disposed wheels the guide means thereof which include the cross connection and the guide members coupled by this cross connection, have a substantially horizontal axis of rotation disposed in a vehicle cross plane and common to both axle sides whereas during oppositely directed spring movements of the oppositely disposed wheels, an axis of rotation is formed for each axle side by the guide means including the cross connection and the guide members coupled thereby, which is determined by the points of pivotal connection of the associated guide member on the frame-side and is disposed at an angle to the common axis of rotation; the cross connection thereby includes a cross bearer which is rotatable about an axis fixed at the vehicle frame and disposed in a vehicle transverse plane, and connecting arms adapted to be torsionally stressed with respect to the cross bearer member and connected to the guide members; the points of pivotal connection on the frame-side of the guide members which are operatively connected to the cross connection and of which at least the inner point of pivotal connection located nearer the vehicle longitudinal center plane is provided at the cross bearer, are located in straight lines extending obliquely to the axis of rotation of the cross connection as viewed in rear view, and constituting the axes of rotation of the guide members for the oppositely directed spring movements.
Abstract:
A distance warning installation for vehicles, especially for motor vehicles, in which each vehicle is equipped with one or two transmitters, radiating beams of light or other waves toward the rear, as well as with a forwardly directed receiver mounted at the vehicle front end for receiving the same types of waves; when the waves of the directional beam transmitted by the preceding vehicle are received by the receiver of the following vehicle, an acoustic and/or optical signal is produced by the receiver and/or a braking operation is automatically initiated thereby.
Abstract:
A bumper for motor vehicles, especially passenger motor vehicles, which is arranged in front of or to the rear of the frame-like support structure and whose center part possesses at least one hollow profile that is delimited on both sides by lateral parts; the hollow profile is provided with outwardly projecting webs that are constructed as connections or mounts for mounting supports and/or one or several elastic profiles.
Abstract:
A servo-steering for motor vehicles in which a steering nut is rotatably and axially non-displaceably supported in the working piston and is helically movably connected with a steering worm axially non-displaceably secured with respect to the gear housing; the axis of the steering shaft in meshing engagement with the working piston by appropriate toothed arrangements as well as the axis of the control slide valve member are disposed in the center stroke position of the working piston in a common diametric plane of the gear housing; the axis of the control slide valve member extends perpendicularly to the axis of the steering shaft and the steering shaft is provided with a single toothed segment whose tooth width at the root is disposed approximately centric to that axial plane of the gear housing which is perpendicular to the axis of the steering shaft and contains the longitudinal axis of the working cylinder; the working piston, within the area of its toothed rack profile, is provided with a radial aperture for the insertion of the steering nut, and the center axis of this aperture extends perpendicularly to the longitudinal axis of the working piston.
Abstract:
An installation for the lubricating of a bearing, especially for rocker arms of internal combustion engines of motor vehicles with a first oil supply groove extending in the circumferential direction and provided at the inner surface of a bearing sleeve, into which terminates a radial oil supply bore of a pin; a second oil supply groove is provided in the bearing sleeve which extends essentially in the same direction as the first oil supply groove and at a distance therefrom; the pin on which the bearing sleeve is rotatably supported, is provided with a recess which, in the starting position of the bearing sleeve, overlaps only one oil supply groove and which so connects the two oil supply grooves with each other upon a slight rotary movement of the bearing sleeve that the previously interrupted oil supply is lifted and the lubricating oil which is now under pressure, is conducted to lubricating oil places by way of the second oil supply groove.
Abstract:
An independent suspension for the front wheels of motor vehicles by means of two guide members disposed one above the other whose pivot axes intersect in the center position of the wheel, on the one hand, as viewed in side view, at a relatively large distance to the rear of the front wheel and below the wheel center and, on the other, as viewed in plan view, at a relatively large angle; the pivot axis of the upper guide member, as viewed in plan view, thereby extends rearwardly outwardly approximately diagonally while the pivot axis of the lower guide member extends either parallel to the vehicle longitudinal axis or at a small angle thereto.
Abstract:
A driver cab for trucks equipped with an internal combustion engine arranged underneath the driver cab, in which air guide members extending in the generally vertical direction and projecting laterally and/or rearwardly beyond the contours of the driver cab are arranged within the areas of transition of the rear wall to the lateral surfaces of the driver cab to prevent the flow of warm air and/or exhaust gases from the internal combustion engine to within the area of the side windows of the driver cab.
Abstract:
A device for adjusting and retaining the valve play in internal combustion engines, especially in motor vehicle internal combustion engines in which a transmission member such as a rocker arm controlled by a cam cooperates with the valve stem by way of an adjusting member, for example, in such a manner that the rocking lever arm abuts with one end on the valve stem and with the other end on an abutment operating as adjusting member which is constructed in the manner of a piston sliding within an oil-filled cylinder and equipped with a check valve; the abutment thereby is formed by a first piston which dips into the housing and which receives with its inner end a second piston that is located in the connection between the pressure space and the reservoir space; the second piston accommodates a check valve closing off this connection; the second piston is also adapted to be fixed with respect to the first piston by a clamping device which is axially movable with respect to the first piston by the predetermined valve play.
