Abstract:
A ventilator roof for use in motor vehicles with a roof opening made in a front part of a fixed roof skin. The roof opening can be closed by a single cover that can be swung, by pivoting around a pivoting axis at or near its rear edge, into a ventilation position in which the cover front edge is at a distance below the fixed roof surface, while the cover rear edge is kept approximately at the height of the fixed roof skin. Starting from the ventilation position, the cover can be lowered at its rear edge below the fixed roof surface and can then be slid as a whole rearwardly under the roof skin into an open position that at least partially opens the roof opening.
Abstract:
Vehicle roof having a front cover and a rear cover adjoining each other in the longitudinal direction of the vehicle which, in a closed position, close a roof aperture in a fixed roof surface.Due to the effects of pure translational movement, the front cover is rearwardly displaceable into an open position, while the rear cover can be moved into a position permitting a sliding back of the front cover thereover. In accordance with the invention, the rear cover can be pivoted around an axis near its rear edge into a venting position, in which the front edge of the rear cover is lowered, relative to the rear edge of the front cover (FIG. 3).
Abstract:
A vehicle roof having a cover which, at its front edge, is displaceably guided in lateral guide rails extending below a fixed roof surface, and which is additionally supported at the guide rails by lifting levers. The lifting levers are connected at one end with the corresponding guide rail, and at the other end with the cover, and are both translatable in the vehicle longitudinal direction and pivotable around parallel axes. During the longitudinal movememt, the levers pivot as a result of interaction with a roof-mounted retaining bracket. The cover can be closed, can be lifted above the fixed roof surface into a vent position by a pivoting movement about an axis at or near its front edge, and can be retracted rearwardly over the fixed roof surface. For the longitudinal movement of the cover, and of the pivotal axis, located at one end of the lifting lever, there are provided separate drive components, which are in permanent engagement with the cover, or with one of the lifting lever ends, respectively.
Abstract:
Hollow chamber seal for sealing an edge gap between an edge of a fixed roof section and a movable cover of a vehicle roof in which both a deformation of the hollow chamber and an additional deformation of the seal are possible to compensate for the gap tolerances. In accordance with preferred embodiments, to produce the additional deformation, at least one hollow chamber part is connected to a sealing body for pivotal movement around a bending axis that extends substantially parallel to the major surfaces of the cover in a direction parallel to the edge of the cover. Using such a seal, in accordance with process aspects of the invention, surface tolerances of a movable cover of an automobile roof can be compensated for by inserting the cover with the attached hollow chamber seal into a template, bringing the hollow chamber part into a pivoted position that corresponds to predetermined external measurements of a roof unit including the cover and the hollow chamber seal, and by attaching the hollow chamber part to the sealing body in this pivoted position. In accordance with this process, a roof unit is produced which will appropriately fit in sealed relation to an edge of a fixed roof section defining a roof opening to be closed by the cover despite tolerance variations in, e.g., the dimensions of the cover.
Abstract:
A cold and/or heat accumulator has a first heat exchanger and preferably a second heat exchanger. The first heat exchanger may, in particular, be provided to be perfused by a refrigerant while the second heat exchanger is preferably perfused by brine. The first heat exchanger and preferably also the second heat exchanger are engaged in a heat-exchanging relationship with carrier elements charged with a cold or heat storage medium and may, in particular, be formed by graphite strips.
Abstract:
The invention relates to a heating and air-conditioning system (10) for a motor vehicle, in particular a utility vehicle, in order to heat or cool the inside of a motor vehicle during a journey and when the motor vehicle is stationary. The inside of the motor vehicle is divided into a front region and a back region, which can be heated and cooled separately, and comprises a front system (12) which is used to heat and cool the front region during a journey of the motor vehicle, a rear system (14) which is used to heat and cool the rear region during a journey of the motor vehicle and a stationary system (16) which is used to heat and to cool at least the rear region when the motor vehicle is stationary. According to the invention, the stationary system is integrated into the rear system. The invention further relates to a method for heating and air-conditioning a motor vehicle by means of a heating and air-conditioning system (10).
Abstract:
A heat exchanger arrangement is made available for heating an area of a vehicle which is to be heated, having: a first heat exchanger element for transmitting waste heat from at least one vehicle electrical component to be cooled to air, and a second heat exchanger element for transmitting heat from at least one vehicle heating device to air. The first heat exchanger element and the second heat exchanger element are arranged in such a way that air (L) to be heated is successively applied to them.
Abstract:
The invention relates to a control device (12) for an engine-independent heater (3) that heats a liquid heat transfer medium of a heat transfer medium circuit (1) especially for motor vehicles. Said control device (12) reduces a heater (3) capacity when an actual temperature gradient ((dT/dtIst) of the heat transfer medium is equal to or exceeds a temperature gradient threshold value ((dT/dt)Schwell). The control device (12) determines the temperature gradient threshold value ((dT/dt)Schwell) dynamically in accordance with a difference in temperature (Δφ) between a target temperature (φSoll) of the heat transfer medium and an actual temperature (φIst) of the heat transfer medium. The invention further relates to a heater (3), a heating system (1), and a method for controlling the inventive heater (3).
Abstract:
The invention relates to a heat exchanger for a mobile heating device comprising a burner, the heat exchanger having a carrier body with an inner face and an outer face. The inner face of the carrier body is formed as an inner exhaust gas duct for conducting exhaust gas of the burner. Furthermore, a channeling is arranged between the inner face and the outer face of the carrier body for conducting a heat transfer medium. The heat transfer medium is in heat conducting contact, via the inner face, with exhaust gas in the inner exhaust gas duct. At the outer face of the carrier body, an outer exhaust gas duct for conducting exhaust gas of the burner is provided. The heat transfer medium is in heat conducting contact via the outer face of the carrier body with exhaust gas flowing in the outer exhaust gas duct. The present invention further relates to a mobile heating device having a burner and to such a heat exchanger and to a motor vehicle comprising such a heating device.
