Patent DE-3714719-A1 (DE)
Title: Drive train for transmitting a torque
Inventor: KOCH WERNER DIPL ING
IPC: B60K17/22
Filed: 1987-05-02
Abstract: Known drive trains in normal commercial vehicles with a cardan-mounted propshaft between transmission and differential can transmit only limited propshaft torques for given dimensions. A larger diameter of the propshaft leads to considerable vibration problems in the inevitably irregularly rotating propshaft centre section. The object of the invention is to create a drive train of comparatively simple construction for transmitting high torques whilst preventing the irregularity as in the prior art and avoiding high external support forces in the frame. According to the invention the drive train (1) has two drive shafts (2, 3) arranged parallel to one another and driven in opposite directions. In the contra-rotating drive shafts (2, 3) the drive torque is divided into two equal component torques, directed in opposition and compensating for one another in relation to the external support, as a result of which not only the external irregularity of the dynamic drive forces is eliminated, but also the support forces on the vehicle frame are reduced. <IMAGE>

Patent DE-3724544-A1 (DE)
Title: Method and circuit arrangement for transmitting television signals
Inventor: AMOR HAMED DR
IPC: H04N7/24
Filed: 1987-07-24
Abstract: For reasons of signal regeneration, it is expedient to transmit television signals over long transmission paths in digitised form. In the case of linear digitising of television signals, unsatisfactory utilisation of the available transmission networks occurs, for which specific standards have already been defined. The invention creates a remedy for this and leads to improved utilisation of the available transmission networks. This is achieved on the one hand by the control and/or synchronisation signals contained in the television signals being subjected to data reduction, which can be implemented easily, while the image content signals are in contrast transmitted in an unrestricted manner so that no deterioration of the image quality occurs, and on the other hand by selecting the sampling frequency to be close to the Nyquist limit with the aid of a suitable digital filter, without any complex anti-aliasing filters being required. <IMAGE>

Title: Wheeled vehicle with two adjacent rigid axles, each with independent suspension
Inventor: RIECK GERHARD
IPC: B60G5/047
Filed: 1988-04-18
Abstract: A suspension comprising a combination of the following features is proposed for a wheeled vehicle in which two adjacent rigid axles (2, 3) are respectively supported on the vehicle frame (1), each by way of two leaf spring elements (7, 8). The leaf spring elements (7, 8) are arranged inclined at an acute angle @ to the vehicle road contact plane (12), rising towards the rear. The front and rear leaf spring elements (7, 8) on each side of the vehicle partially overlap one another and are connected by their ends in the overlap area to a common support element (10). This is designed as bearing bracket in such a way that it simultaneously serves as the element absorbing the axle lateral forces of both rigid axles (2, 3). Each leaf spring element (7 and 8), viewed in the direction of travel (4), is rigidly connected to a support element (9 and 10) at the front, but otherwise suspended on a short axle beam (14 and 16) so that it overhangs at the rear. Furthermore, the distance (d) from the front bearing point (11) of a front leaf spring element (7) to the middle of the front rigid axle (2) is greater than the distance (f) of the front bearing point (16) of a rear leaf spring element (8) from the middle of the rear rigid axle (3). This results in a robust spring arrangement of very low height on the wheel vehicle, with favourable absorption of lateral forces. <IMAGE>

Title: Lateral guidance device for a lateral guidance wheeled vehicle
Inventor: THUDT HUBERT
IPC: F16C11/10
Filed: 1989-02-21
Abstract: The invention relates to a lateral guidance device for a lateral guidance vehicle in which a sensing roller (2) which interacts in lateral guidance mode with a lateral guidance wall (6) is arranged by means of a roller axle pin (8) on a roller holder (3) which is attached to a sensing arm (1). The roller axle pin (8) is held so as to be movable on all sides in the roller holder (3) with a ball head (16) provided on the said roller axle pin (8). In order to block the sensing roller (2) in the normal position, the ball head (16) is pressed against a roller holder-side counter bearing surface (26) by means of a locking element (28) which is spring loaded and dips into a depression provided on the said ball head (16). The holding force is preferably adjusted by means of a plate spring (34). By overcoming this holding force which is set and transmitted in such a way, the sensing roller (2) can be pivoted out of its normal position. As a result, damage to the roller holder (3) or parts of the sensing roller bearing and to the elements transmitting the lateral guidance movement can be avoided. <IMAGE>
