Description

The present invention relates to a fixation

  radiator for a motor vehicle, where the radia-

  the driver is placed with the aid of at least one support portion integral with the radiator respectively on a corresponding support portion secured to the vehicle, and - further comprising a support fixed on the radiator, a counter-support disposed on a integral part of the vehicle, a cuff-shaped damping lining and an elastic fastener, which holds the support on the counter-support via

the damping lining.

  A radiator fastener of this type is described in patent DE-25 57 967. In the known radiator fixing, it is provided on the radiator a

  support which is applied by one of its

  mediate an elastic damping means, fixed on it, against a support integral with the vehicle. The support provided on the radiator is held together with the damping means and the solidarity support

  of the vehicle with the aid of an elastic fastener

  corn. In this way it avoids a tilting of the radiator around its lower support plane. The

  damping means arranged around the solid support

  the radiator is supported upwards against a portion, serving as a counter-support, of the elastic fastener and thus prevents an uprising of the support portion integral with the radiator relative to the part

solidarity support of the vehicle.

  A disadvantage of this radiator fixing, characterized by a simplicity of fixing, is that the maintenance of the radiator to prevent an uprising of its support part is not

  produced directly but indirectly through

  medial damping means and an elastic fastener on a portion integral with the vehicle. The unavoidable manufacturing tolerances existing for the radiator between the support part and the support integral with the radiator as well as for the vehicle between the support part and the support integral with the vehicle require to allow a certain movement.

  relative between the radiator and the elastic fastener.

  Tolerance compensation is carried out, for the known radiator attachment, by force conjugation

  by compressing the damping means.

  Another disadvantage is that there is a risk of rust formation due to the floating movements of the elastic fastener on the

solidarity support of the vehiculo.

  The object of the invention is, while maintaining the advantages indicated above, that is to say a simplicity of embodiment and ease of assembly, of arranging a radiator fixing of the type defined above so that a safer fixation of the radiator by preventing it from being lifted

  while ensuring the compensation of tolerances.

  The problem is solved in accordance with the invention in that the damping lining is provided on the solid parts of the vehicle and is arranged at its lower end in the form of an elastic wedge widening towards its free end and which, in the assembly condition

  radiator, is applied against a corresponding surface

  convex side of the damping lining.

  This damping lining, provided with a mounting opening which can be closed by means of a toothed covering portion, is placed around a support integral with the vehicle. For a compensation of tolerances between the radiator and the vehicle in the vertical direction, the damping lining comprises at its lower end, as indicated above, a movable elastic wedge

  widening towards its free end.

  The support integral with the radiator moves, during assembly, this corner in a horizontal direction so that it comes to lock between the support and the corresponding convex bearing surface of the damping lining. In this way, it is ensured to obtain a compensation of tolerances in the vertical direction by conjugation of forms and the radiator leans firmly against its height abutment part. Holding the radiator towards the

  top is insured directly against the bodywork.

  The whole is maintained with the help of an elastic fastener

  that Yes hangs in a notch: 'stop provided on the support solidarity of the radiator and which can be detached with the help of a draw hook to maneuver with the fingers. This elastic tie guarantees

  a safer closure of the cushioning lining

  by means of its covering part: it is also inserted during a request by oscillations. Other features and advantages of the invention will be demonstrated in the following.

  description, given by way of non-limiting example,

  Referring to the accompanying drawing in which: Figure 1 shows a radiator attachment according to the invention, with partial elevational view of the radiator in the direction of travel, Figure 2 is a sectional view of a radiator attachment. according to the invention, made according to

  section line II-II of Figure 1.

  On a radiator 1, shown in view partial elevation in Figure 1 and which rests with its lower support portion, not shown, against a support portion secured to the vehicle and é5alement

  not shown, there is provided on each side of the radiator 1, a support 3 for fixing the radiator i on a part 4 secured to the vehicle, for example on a top rail of the vehicle,

  S each support 3 being connected to the radiator through

  2. Each support 3 rests against the part 4 secured to the vehicle so as to be prevented from tilting in the direction of travel and it is provided for this purpose on this

  part 4, in the support zone, a cushioning pad

  5 to prevent tilting of the radiator 1 in a direction opposite to the direction of travel, the fixing device consisting of the part 4 integral with the vehicle, the damping lining 5 and the support 3 is held together. and is blocked by means

  an elastic fastener 6 engaged on it.

  A radiator fastener according to the invention

  This is shown in Figure 2 on a scale. larger

  and according to the section line II-I of FIG.

  To simplify the drawing, the radiator, designated 1 in FIG. 1, and the connecting piece 2 have not been shown. Identical parts are designated by the same reference numerals as in FIG. 1. The integral part 4 of the vehicle is provided with a recess 7 through which the packing passes.

  depreciation 5 which is fixed on this part.

  For this purpose, the damping lining 5 is provided with a mounting opening 3. After the damping lining 5 has been engaged through the recess 7 so as to surround the integral part 4 with its corresponding shape. of the vehicle and having two bends, the mounting opening 3 is closed by a toothed overlap portion 9 and the damping lining 5 is held in this position. When mounting the radiator, it is moved by its support 3 against the seal

  5 until it goes into abutment.

  The lower edge 10 of the support 3 then pushes the lower end, arranged in the form of an elastic wedge 11, of the damping lining 5 from its basic position shown in phantom in its position of application against the surface.

  corresponding stop 18 of the damping pad

  5. When the radiator, not shown, is securely applied against its bottom support, also not shown, the elastic corner 1! is blocked between the corresponding convex abutment surface 13 and the support 3. In this way, one always obtains, by conjugation of forms, a

  vertical tolerances between the radia-

  1 and the part 4 secured to the vehicle. The support 3 then bears directly against the integral portion 4 of the vehicle. To secure the radiator, is engaged on the assembly thus formed an elastic fastener 6, penetrating by one of its branches 12 in the recess 7 formed in the part; secured to the vehicle and which clings by its lug 13 in a notch 15 formed by the support 3 and its profiled portion 14 projecting forwardly. In this hooking position, the elastic fastener 6 holds the damping lining 5 in its closed position,

  also during a request by oscilla-

  tions. The other branch 15 of the elastic fastener 6 is profiled below the lug 13 like a pull hook 17 to be operated by the fingers and it allows simple disassembly of the radiator fastener according to the invention, since the hook is not masked by parts of the bodywork and is for this

reason easily accessible.

  Another advantage of the fixation of radia-

  according to the invention consists in that the elastic fastener 6 is separated from the portion 4 secured to the vehicle by the damping lining 5 and that there is therefore no metal contact, so that the problems of corrosion that can result are thus eliminated. This problem does not exist for the connecting surface between the support 3 and the elastic fastener 6 because the support 3 is not metallic but consists of a material

  plastic as the radiator water collector 1.
