Definitions
- the invention relates to a method for connecting the heating rod a glow plug with the glow plug body, wherein the Heating rod inserted into the axial bore of the glow plug body is and by a radial force on the glow plug body a central interference fit between the glow plug body and the heating element is generated.
- the heating element to connect a glow plug to the glow plug body thereby that on the Schustabober Design several circumferential grooves be applied and this with a temperature resistant Liquid to be filled. After inserting the heating element in the glow plug body is from the outside of the glow plug body Body material pressed into the grooves of the heating element. Around To make this connection dense it is necessary, in addition to use the heat-resistant liquid.
- JP-A-01046520 it is also known to connect the glow plug body to the heating rod by deforming both parts inwardly by a radial force.
- the heating element to connect a glow plug to the glow plug body thereby that the heating element on a pressing surface with molded grooves provided and pressed axially into the glow plug body.
- the heating element of a glow plug with the glow plug body by pressing the heating element in the To connect glow plug body.
- a hydraulic Pressing device used, which has a centric press fit generated between the heating element and the body.
- the Heating rod axially from the combustion chamber side glow plug tip ago pressed the glow plug body.
- the required axial Force on the top of the heating element is strong on the tolerances the body bore and the heating rod diameter and the depending on the surface finish. Since the Vorstehnies of the heating rod from the glow plug body an essential parameter the function of the glow plug in assembly and engine operation, the press-fit path must be monitored during assembly.
- the high press-in force is especially in thin and relatively long heating rods the risk of damaging the Heating rod by buckling, tilting, scoring or deformation, so that the pressing force a predetermined maximum value must not exceed. Therefore, the press-in force must be be monitored during the press-fitting process.
- the Kraftwegüberwachung is technically complex, the long press-in combined with the high press-in forces involves identified risks. For coated heating rods In addition, the coating is destroyed.
- the object underlying the invention in to provide a method of the type mentioned, with in a simple way a solid and dense axial interference fit can be generated.
- a particularly preferred embodiment of the invention The method is the subject of claim 2.
- the heating element 1 is centered in the body 2 positioned, for example, inserted, wherein Diameter of heating element 1 and bore in the body 2 accordingly matched to each other, so that the slot with low power can be done. This is on simple Way the heater 1 is axially aligned; beyond that he very exactly with the least long tolerances axially on the desired Vorstehberger with respect to the body 2 positionable.
- the crimping region 3 for example by means of a crimping tool according to FIG. 3 of the glow plug body 2 crimped over the heating element 1; preferably extends the crimping region extends axially over a length of about 20 mm.
- crimping occurs in this area a reduction in diameter of the body 2.
- the crimping is preferred approximately in the middle above the area of the heating rod 1, the is disposed within the body 2.
- the crimping tool according to FIG. 3 has a turntable, six crimping jaws 4 and feather key 5.
