Fastening device for a heat exchanger unit and vehicle equipped with a heat exchanger unit

Abstract

A fastening device for a heat exchanger unit ( 10 ) on a vehicle comprises, on each side of the vehicle, an upper and a lower fastening point ( 15, 16 ). The heat exchanger unit ( 10 ) is, via the fastening points ( 15, 16 ), fastened on both sides at least indirectly to the vehicle frame. To this end, a retaining bracket ( 11 ) is provided that joins the upper and lower fastening points ( 15, 16 ) to one another, this retaining bracket ( 11 ) being able to be fastened at least indirectly to the vehicle frame longitudinal member. The heat exchanger unit ( 10 ) is only fastened to deformation elements ( 12 ) that join the members ( 13 ) subject to bending to the frame longitudinal members ( 14 ) of the vehicle.

       2 . A fastening device for a heat exchanger unit on a vehicle, the heat exchanger unit having a first and a second fastening point and being fastened at least indirectly to the vehicle frame via the fastening points wherein a holding bracket is provided which connects the first and the second fastening point to one another, the holding bracket being fastenable at least indirectly to the vehicle longitudinal member. 
   
   
       3 . The fastening device as claimed in  claim 2 , wherein at least one vibration damper is provided at the at least the first or the second, fastening point between a holding element and the heat exchanger unit. 
   
   
       4 . The fastening device as claimed in  claim 2 , wherein the holding bracket projects out of the connecting plane of the fastening points in the vehicle longitudinal direction and can be fastened vertically at two adjacent fastening locations lying one above the other. 
   
   
       5 . The fastening device as claimed in  claim 4 , wherein the holding bracket is of essentially D-shaped design. 
   
   
       6 . A heat exchanger device with at least one heat exchanger, preferably a plurality of heat exchangers, having a fastening device as claimed in  claim 1 . 
   
   
       7 . A vehicle with a vehicle frame with longitudinal members spaced apart from one another and with a bending member which connects the longitudinal members to one another in the transverse direction and runs in front of the longitudinal members, with deformation elements arranged between the longitudinal member and bending member, and with a heat exchanger unit fastened to the vehicle frame, wherein the heat exchanger unit is fastened only to the deformation elements. 
   
   
       8 . The vehicle as claimed in  claim 7 , wherein the fastening location of the heat exchanger unit on the deformation element is selected in such a way that the heat exchanger unit remains free of damage in the event of a maximum deformation of the deformation element. 
   
   
       9 . The vehicle as claimed in  claim 8 , wherein a free space is formed between the heat exchanger unit and the assembly lying behind it, the heat exchanger unit being displaced rearward by the amount of no more than the free space in the event of a maximum deformation of the deformation element. 
   
   
       10 . The vehicle as claimed in  claim 7 , wherein at least one of the elements comprising the bending member and the deformation elements has in each case at least one flange for fastening to one another, the heat exchanger unit being fastened to one of these flanges. 
   
   
       11 . The vehicle as claimed in  claim 10 , wherein the heat exchanger unit is held on the fastening flange of the bending member. 
   
   
       12 . The vehicle as claimed in  claim 7 , wherein the heat exchanger unit is fastened to the deformation elements a fastening location for the heat exchanger unit being formed on the deformation elements. 
   
   
       13 . The vehicle as claimed in  claim 7 , wherein the heat exchanger unit is fastened by means of a holding bracket, the holding bracket being designed so that the heat exchanger unit has at least one fastening point and is fastened at least indirectly to the vehicle frame via the at least one fastening point. 
   
   
       14 . The vehicle as claimed in  claim 7 , wherein the heat exchanger unit is fastened by means of a holding bracket, the heat exchanger unit having a first and a second fastening point and being fastened at least indirectly to the vehicle frame via the fastening points, wherein the holding bracket connects the first and the second fastening point to one another, the holding bracket being fastened at least indirectly to the vehicle longitudinal member. 
   
   
       15 . The vehicle as claimed in  claim 14 , wherein at least one vibration damper is provided at the at least the first or the second fastening point between a holding element and the heat exchanger unit. 
   
   
       16 . The vehicle as claimed in  claim 14 , wherein the holding bracket projects out of the connecting plane of the fastening points in the vehicle longitudinal direction and can be fastened vertically at two adjacent fastening locations lying one above the other. 
   
   
       17 . The vehicle as claimed in  claim 16 , wherein the holding bracket is of essentially D-shaped design.
