Description

2263677 1 P adiator attachment for motor vehicles The invention relates to
a radiator attachment for motor vehicles.
German Patent Specifications 3,926,568 and 3,926,569 disclose radiator attachments, in which the radiator is seated in a flexible manner by means of at leas t one mounting, which is fixed to the radiator, in each case on a corresponding mounting which is fixed to the vehicle, and in which the radiator is supported in a flexible manner via at least one attachment element on a support which is fixed to the vehicle. Additionally, means are provided which allow compensation of production tolerances.
The present invention seeks to improve a radiator a.'L--ta.ch-rt.en4t-- in such a way tChat compensation of production tolerances in any direction is made possible in a simple manner With a low constructional height- The term radiator includes, inter alia, heat exchangers such as the radiator for the engine cooling water and an air conditioning condenser.
According to the present invention there is provided a radiator attachment for motor vehicles, having at least one lower flexible bearing point which supports the radiator in the vertical direction and fixes it positively in the horizontal direction, in which the radiator is adapted to be supported in a flexible manner on a support, which in the installed condition, is fixed to the vehicle, via at least one attachment element which is arranged in the upper region of t_he radiator, wherein the attachment element has a pin which is mounted rotatably via a flexible element, surrounding said pin, in a receiving bore of a holding element which is firmly connected to the radiator, and the attachment element has an elongate hole which is arranged with spacing from the pin and extends in a plane perpendicular to the axis of rotation of the pin.
When the radiator is installed, compensation of production tolerances in any direction is possible with a 2 low constructional height due to the combination of the rotatably mounted pin and the elongate hole in the attachment element. The tolerance compensation can be carried out simply and quickly since, for this purpose, the elongate hole only has to be brought into congruence with the bore in the support, which is fixed to the vehicle, by turning the attachment element about the pin.
The support may be a constituent of a further radiator which, in turn, is adapted to be attached to a bodywork support of the motor vehicle. This embodiment allows the attachment of a second heat exchanger, for example an air-conditioning condenser, to the first radiator, for example the radiator for the coolant of the engine. This affords the advantage that both or, if appropriate, a plurality of radiators can be preassembled to simplify the installation.
The flexible element may be a rubber bush adapted to be pressed into the receiving bore, and the elongate hole may extend in the attachment element substantially along the connecting line between tine elongate hole and the pin. The attachment element may be attached by means of a screw to the support which is adapted to be fixed to the vehicle.
An exemplary embodiment of the invention is described with reference to the drawing, in which Figure 1 shows a cross-section through the radiator attachment according to the invention and Figure 2 shows the upper part of the radiator attachment according to the invention in a perspective view.
The drawing shows a first radiator 1 which is attached to the bodywork (not illustrated in detail) of a motor vehicle, and in which a support 4, which is provided with a bore 3 and extends parallel to the upper edge of the front of the radiator, is integrated for receiving a second radiator 2. The second radiator 2 is supported on a bodywork support 7 via two rubber bearings 5 which are arranged spaced apart and in each of which there is inserted a bolt 6 which is moulded onto the underside of the second radiator 3 2, said bodywork support having two cutouts 8 to receive the rubber bearings 5.
The upper side of the second radiator 2 is covered by an end plate 9. In the end regions of the end plate 9 facing the narrow sides 17 of the radiator, a holding element 10 is moulded in each case onto the rear edge of the end plate 9 in such a way that it runs parallel to theback of the radiator with spacing therefrom and extends into the region above the second radiator 2. The offset between the holding element 10 and the back of the second radiator 2 is dimensioned such that the second radiator 2 does not rest radiator 1.
against the L A receiving bore 11 is introduced into each of the two holding element 10. Pressed into the receiving bore 11 is a rubber bush 12 into which a pin 14 is then inserted, said pin being moulded onto an attachment element 13. The two radiators 1, 2 are thus completely uncoupled f rom one another in terms of vibration due to the flexible elements 5, 12. The rubber bush 12 has an annular groove 15 to receive the holding element 10, thus preventing movement of the rubber bush 12 against the holding element 10. Arranged at the end of the attachment element 13 located remote from the pin 14 is an elongate hole 16 which extends substantially along the connecting line between the bolt 14 and the elongate hole 16. The pin 14 is moulded onto the attachment element 13 at a right angle, such that the elongate hole 16 is arranged in a plane perpendicular to the axis of rotation 18 of the pin 14.
The attachment element 13 and the support 4 are of stepped construction, such that the attachment element 13 rests against the support 4 in the region of the elongate hole 16, but a gap is f ormed in the region of the pin 14 between the support 4 and the attachment element 13 in such a way that the rubber bush 12 fitted over the pin 14 rests positively both against the support 4 and against the attachment element 13. As a result, the installation position of the rubber bush 12 and thus of the entire second 4 radiator 2 is f ixed. Furthermore, it is also possible to construct only the attachment element 13 or the support 4 in a stepped manner.
Prior to installation of the second radiator 2, the rubber bush 12 is f irstly pressed into the receiving bore 11 and the pin 14 moulded onto the attachment element 13 is then inserted into the rubber bush 12. The second r-adiator 2, thus preassembled, is then inserted into the lower rubber bearing 5, as a result of which it is supported in the vertical Dlane and fixed positively in the horizontal plane. The inclination of the front of the radiator relative to the vertical direction is determined by the attachment element 13 resting against the support 4 which is fixed to the vehicle. Tolerance compensation in any direction parallel to the back of the radiator is possible due to the combination of the pin 14, which is mounted rotatably substantially aboUtL an axis in the longitudinal direction of the vehicle, with the elongate hole 16 arranged in the attachment element 13. For this purpose, the attachment element 13 is turned aboutl the pin 14 until the elongate hole 16 and the bore 3 on the support 4 which is fixed to the vehicle are completely congruent, such that the attachment element 13 can be attached to the support 4 which is f ixed to the vehicle by means of a screw which is screwed into said bore 3.
The tolerance range which can be compensated by the attachment element 13 results as the difference between Lhe maximum and the -minimum spacing between the axis of rotation 18 and the elongate hole 16. The arrangement of the elongate hole 16 along the connecting line between the elongate hole 16 and the pin 14 is therefore particularly advantageous since, in this case, the tolerance range is equal to the length of the elongate hole 16. In addition, however, any other arrangement in which the elongate hole 16 is arranged in a plane perpendicular to the axis of rotation 18 is also conceivable.
In addition to the arrangement described above, wherein the second radiator 2 is attached to a support 4 of the first radiator 1, the radiator attachment according to the invention can also be used for the purpose of mounting an individual radiator directly on a correspondingly shaped support which is fixed to the vehicle. The number of lower and/or upper bearing points can likewise be varied as desired.
