The aim of the invention is to build central receiver solar power plants in which the heliostat fields can be used more efficiently. To achieve said aim, a heliostat field consisting of a near field having a uniform reflector surface density ρ of more than 60% is preferably combined with a far field whose reflector surface density ρ decreases as the distance from the receiver increases. The invention also comprises central receiver solar power plants which consist exclusively of a near field having a uniform reflector surface density ρ of more than 60%. The high reflector surface density ρ in the near field and in areas of the far field is achieved by the use of heliostats having rectangular reflectors and a rigid horizontal axle suspension (FHA) or, alternatively, by heliostats having rectangular reflectors and a rigid quasipolar axle suspension (FQA). The heliostat field concentrates the solar radiation on a receiver whose target surface, aperture, thermal absorber or photovoltaic absorber has a normal vector which is directed downward to the heliostat field that extends below the receiver in the directions North, East, South and West. The receiver is mounted in a suspended manner to a support structure that extends over the heliostat field.

A convertible vehicle with a roof, which can be stowed in the rear region of the vehicle and comprises at least one front roof part, which faces a windshield frame in the closed position, and a rear roof part, which extends backward and downward at the rear and has, at its side edge regions, frame parts, which are held at their rear end regions so that they can be swiveled about a horizontal axis. In such a vehicle, in order to increase the headspace for the passengers, especially in the case of four-seater convertible vehicles for the passengers on the rear seat, and to improve the optics in the connecting region of the folding top, without significantly enlarging the stowage space for the open folding top, provisions are made so that the axis mentioned lies above the window parapet in the closed position of the roof and, for this purpose, over connecting frame parts, which are linked to the rear end regions of the rear frame parts so that they can be swiveled, are at a distance from the main bearing, which is on the car body and about which the roof can be swiveled, at least one part region of the connecting frame part, lying above the window parapet, enclosing an obtuse angle with the window parapet in the driving direction.

A convertible device of a vehicle comprises a convertible top (10) movable between a closed position and a folded-together, lowered open position and a separating wall (22, 24) separating the convertible top at least in its folded-together open position at least partially from the interior of a luggage space (19) of the vehicle when the convertible device is mounted thereon. At least a portion of the separating wall is formed by a rear shelf part (24) that separates the passenger compartment from the luggage space in the closed position of the convertible top and during movement of the folding top into its open position moves downwardly together with the lower, rear edge portion of the convertible top, so that the folded-together convertible top is disposed above the rear shelf part. A sensor apparatus detects an object located in the luggage space and hindering a lowering of the rear shelf part.

A convertible vehicle with a roof, which can be folded up, is provided with a rear window, can be stowed in a rear region of the vehicle and is braced over at least one tension bracket in the closed state with respect to the car body, the tension bracket being pivotable in the forwards direction for opening the roof and hereby bringing about a forward displacement of the rear window. In the case of such a construction, in order to be able to carry out the forward shifting of the rear region of the folding top, comprising the rear window, without being obstructed by upright parts, such as the rear head supports or roll bars, provisions are made so that the rear window is held in a frame which, on the folding top side, is opened downward and, during the opening and closing of the roof, can be swiveled up with respect to this frame.

The invention relates to a convertible vehicle with a roof, which can be folded up and is provided with a rear window, it being possible, in the closed position of the roof, to lower the rear window at least regionally from a normal position into a lowered position below a window parapet line forming the upper boundary of the car body. In order to simplify the installation of a movable rear window for such an embodiment, provisions are made so that the rear window, in the lowered position as well as in the normal position, is held in a frame, which is firmly connected with the roof, as a result of which special adjustment of the rear window or of a different component with respect to the roof is superfluous.
摘要:
Apparatus suitable for use in convertible vehicles may include a convertible top comprising a substantially rigid front portion that moves downwardly towards and releaseably engages a windshield frame of the vehicle in order to close the convertible vehicle. At least one dampening device may be disposed at a rear portion of the convertible top and may be operably coupled to the front portion in order to slow downward movement of the front portion during a final phase of a convertible top closing operation. Further, the dampening device may be operably coupled between two pivotably connected linkages provided within the rear portion of the convertible top. The two pivotably connected linkages are preferably arranged and constructed so that the opening distance between the two linkages increases when the front portion is moving downwardly towards the windshield frame.

For a convertible vehicle with a foldable at least partially flexible roof where longitudinal side support components and between these, cross-connecting supports are arranged for the support of at least the flexible roof section, at least one bow is arranged in a longitudinally moveable fashion with regard to the longitudinal side support components and in a movable fashion subject to the opening or closing of the roof via at least one control device.
摘要:
A convertible vehicle (1) with an unfoldable roof (2), which can be placed under a cover (5) in the open position and has at least one rear bracket (4), which rests on the cover (5) in the closed position of the roof (2), and is constructed in such a way that the opening motion of the roof (2) includes a combined lift/rotation motion (13) of the bracket (4).
摘要:
A foldable top for a convertible includes a vehicle body, a windshield frame on the vehicle body, a rear region on the vehicle body disposed rearwardly of the windshield frame, a foldable-rod linkage supportable on the windshield frame, a main power operated device mounted on the vehicle body for moving the foldable-rod linkage between closed and open positions, and a rear roof clamping member at the rear region of the vehicle body. Rail members are pivotably connected to each other and are also pivotably connected to the foldable-rod linkage and to the clamping member. A tensioning linkage is pivotably connected to one of the rail members and pivotably connected to the vehicle body. A drive mechanism mounted on the vehicle body is pivotably connected to the tensioning linkage and is operable to pivot the tensioning linkage which in turn pivots the rail members.
