Abstract:
A motor vehicle roof is provided which includes a roof opening, a movable cover, and a wind deflector coupled to bearing points located laterally with respect to the roof opening such that, in the closed position of the cover, the wind deflector lies between the cover and the roof surface with the deflector's top edge flush with the roof surface. The wind deflector swivels around an axis running through the bearing points when the cover is being opened such that its top edge lies over the fixed roof surface and a side of the wind deflector faces the front edge of the roof opening in any plane which is perpendicular to the swiveling axis. The side of the deflector has a curvature with a radius which corresponds to the distance of the front edge of the roof opening to the swiveling axis of the wind deflector.
Abstract:
A motor vehicle roof with two covers which are arranged in succession and roughly at the height of the roof contour in the closed position. At least part of the front cover is displaced to the rear above the rear cover into the open position for clearing a front roof opening section, and in this open position, the front cover is supported by laterally arranged support levers, each of which are coupled to the rear area of the front cover and are guided in the lengthwise direction of the vehicle in a guide rail located below the roof contour. The guide rail extends laterally outward of the side edge of the roof opening and in the open position the rear cover is lowered below the roof contour and the support lever extends through a gap which is formed as a result of lowering of the rear cover.
Abstract:
Vehicle roof with a cover for, alternatively closing and at least partially opening a roof opening, with a sliding inside roof headliner for, alternatively, closing and at least partially opening a framed opening lying under the roof opening, with a respective drip molding running in the longitudinal vehicle direction under each side of the roof opening, with longitudinal guide mechanisms, along which the cover is displaced by a drive device in the longitudinal direction of the vehicle, extending along the drip moldings; and wherein, according to preferred embodiments of the invention, a water catching device that is located under the rear edge of the roof opening, at least when the cover is in its forwardmost position, and that catches water coming in there and diverts it into the lateral drip moldings, is formed by the sliding inside roof headliner, itself. More specifically, water is collected upon the top surface of the sliding roof headliner and is directed laterally off of its side edges into the drip moldings either directly (by the side edges hanging over the drip moldings) or indirectly (by water ducts that connect to the drip moldings via laterally extending passages).
Abstract:
A process for testing operational components in heaters, especially vehicle auxiliary heaters, in which the operational components are actuated and switched on sequentially, individually. Based on this, a corresponding evaluation is then performed. Further, a testing device for performing the process has a switching-on device with which the operational components can be started up, individually, on a sequential basis. From the process engineering viewpoint and from the device engineering viewpoint, further developments up to integration of the testing device in a heater control device are possible, and, optionally, for evaluation of the operational testing, external devices can also be used.
Abstract:
A process is for the operation of a burner, particularly an exhaust gas burner, which is intended for the regeneration of particle filter device in the exhaust gas section of a diesel internal combustion engine, for example. The burner has a precombusiton chamber, in which precombustion of a mixture of auxiliary air, exhaust gas and fuel is carried. In an afterburning chamber, heat generated from the precombustion chamber is used for the preparation of the fuel fed into the afterburing chamber to accelerate the combustion reaction. A burner intended for this process has a fuel feed device which introduces fuel into the precombustion chamber in a manner such that at least a portion of the fuel passes, in a manner that is substantially unaffected by the combustion in the precombustion chamber, into the afterburning chamber. With the operating process according to the invention and with the burner according to the invention, despite the use of the residual oxygen of exhaust gases in the burner, a rapidly proceeding combustion can be achieved with the least possible construction volume.
Abstract:
A motor vehicle heating system which is provided in a motor vehicle coolant circuit containing a motor vehicle engine, a motor vehicle heater with a heat exchanger and an associated blower, and a fuel operated heating device that is independent of the motor vehicle engine and is connected upstream from the motor vehicle heater, and a process for operating such a motor vehicle heating system, by which the motor vehicle engine in the motor vehicle coolant circuit is heated first to a temperature which is low yet facilitates its starting, and then the coolant is heated so that the motor vehicle heater can provide heat quickly. Until a first predetermined temperature of the coolant is reached, the coolant, is circulated in the complete motor vehicle coolant circuit. Then, the coolant, while bypassing the motor vehicle engine and the motor vehicle heater, is circulated between the intake and the outlet of the fuel operated heating device, until a second predetermined temperature is reached, at which point, the bypass connecting the intake and outlet of the heating device is opened. After reaching and exceeding the second predetermined temperature, the coolant is the, again, gradually circulated in a controlled manner in the complete motor vehicle coolant circuit as the bypass is gradually closed until its final closed position.
Abstract:
Device for actuating at least one helically threaded, incompressible drive cable, which is axially movable, having a drive pinion seated on a drive shaft, and a cable guideway for guiding the drive cable in the area of the drive pinion. For the purpose of noise reduction, boundary edges of the cable guideway contacting the drive cable are of a configuration such that they form an angle with the longitudinal axis of the drive cable which deviates from 90 degrees; whereby an acute approach angle enclosed between the boundary edges of the cable guideway and the sections of the turns of the helical thread facing them, is larger than an acute elevation angle which is enclosed between the helical turns and a vertical plane which extends perpendicular to the longitudinal axis of the drive cable.
Abstract:
A process for operating a fuel-operated heater, in which the instantaneous operating condition of the heater is determined according to appropriate criteria and the maximum producible heating power is adjusted according to it. The instantaneous operating condition of the heater is used as the control value for instantaneous maximum producible heating power to optimize the yield of the heating power of the heater without exceeding safety limits, especially component safety limits. Further, an arrangement for performance the process has a detection device, such as a sensor for determination of a characteristic component temperature, which works together with an adjustment device for adjusting the instantaneous maximum producible heating power. This adjustment device controls the fuel feed device of the heater by an actuator and appropriately changes the amount of fuel fed to the burner of the heater. Additionally, the amount of combustion air fed to the burner can, optionally, be appropriately changed.
Abstract:
The invention concerns a shade system (10,40,50) for a motor vehicle, said system being adapted to obscure a transparent bodywork element. Said shade system comprises at least one shade guideway (12), a winding shaft and lateral guide elements (18, 20) wherein are guided the lateral edges of the shade guideway (12). The lateral edges of the shade guideway (12) have each a flat and flexible driving band (22A, 22B). In order to ensure that said driving bands (22A, 22b) are wound on the winding shaft (16) and are unwound therefrom in specific manner, a lateral winding guide (28A, 28B;42;52) is arranged at the winding shaft (16) for each driving band (22A, 22B), said winding guides (28A, 28B;42;52) preventing the driving bands (22A, 22B) from being laterally offset at the winding shaft.
