CONTROL MODULE OF A VEHICLE

Abstract

A control module of a vehicle includes a plurality of electromechanical functional elements arranged on a carrier plate and fixed in an interlocking and force-fitting manner to the carrier plate by clamping elements. The clamping elements are formed on a pressure plate that is secured to spacers of the carrier plate. To simplify production and fitting of the pressure plate provided with the clamping elements and to be able to use them with functional elements having different structural heights, the spacers have a slightly greater height than the structural height of the highest functional element. The pressure plate, for each of the functional elements, has at least one clamping element in the form of a clamping tab. The clamping tabs are each arranged at an opening in the pressure plate, which opening is partially closed by the clamping tabs, and are angled toward the carrier plate.

DETAILED DESCRIPTION OF THE DRAWINGS

[0025] With reference to FIG. 1, a control module 2 is illustrated in perspective view and includes a carrier plate 4 having a plurality of post-shaped upwardly directed spacers 6, a plurality of electromechanical functional elements 8 arranged on the carrier plate 4, which in the present case, as an example, are solenoid valves, and a pressure plate 14, which is placed on the spacers 6 and the functional elements 8 and is fastened to the spacers 6 by a plurality of screws 26.

[0026] In the sectional view of FIG. 2a and the enlarged detail B from FIG. 2a illustrated in FIG. 3a, the pressure plate 14 is illustrated, in the sectional plane A-A according to FIG. 1, in the non-mounted state. In the sectional view of FIG. 2b and the enlarged detail C from FIG. 2b illustrated in FIG. 3b, the carrier plate 4, the functional elements 8 and the pressure plate 14 are illustrated, in the sectional plane A-A according to FIG. 1, in the mounted state.

[0027] The pressure plate 14 of the present disclosure, in one aspect, is composed of a sheet metal and has a drilled hole 16 for each of the screws 26. In the present disclosure, the structural height HB of the functional elements 8 is the same for all functional elements 8, but it could also differ in magnitude. The spacers 6 are of a slightly greater height H than the structural height HB of the functional elements 8. For the purpose of positively and non-positively fixing the functional elements 8 to the carrier plate 4, the pressure plate 4 is provided with two clamping elements 20, 20′, realized as clamping tabs, for each of the functional elements 8.

[0028] The clamping tabs 20, 20′, as a result of being stamped out on three sides, are each arranged in an opening 18, 18′ in the pressure plate 14 that is partially closed by the clamping tabs 20, 20′, and are bent over toward the carrier plate 4. The two clamping tabs 20, 20′ provided for each functional element 8 are arranged, in mirror symmetry with respect to the geometric center axis 10 of the assigned functional element 8, with their free ends 22 directed toward each other at the respective openings 18, 18′ in the pressure plate 14. The clamping tabs 20, 20′ arranged at each of the openings 18, 18′ may also be point-symmetrical and aligned parallel to each other, similar to the alignment shown in FIG. 5. The clamping tabs 20, 20′ are bent over toward the carrier plate 4 to such an extent that, when the pressure plate 14 is fastened to the spacers 6 of the carrier plate 4, they are plastically and/or only elastically deformed upon their respective outer edge 24 being pressed against the upper outer walls 12 of the functional elements 8.

[0029] As a result of the plastic deformation of the clamping tabs 20, 20′, their elastic tension causes a defined contact pressure to remain upon the upper outer walls 12 of the functional elements 8. It is therefore not necessary for the angling of the clamping tabs 20, 20′ to be executed with precision. Moreover, the openings 18, 18′ with the clamping tabs 20, 20′ do not have to be positioned exactly for fixing the functional elements 8 within the pressure plate 14.

[0030] FIG. 4 shows a detail of a schematic top view of a pressure plate 14 similar to the pressure plate according to FIG. 1. FIG. 4 shows an opening 18″ in the pressure plate 14 that is partially closed by two clamping tabs 21a, 21b. These clamping tabs 21a, 21b are integrally connected to the material of the pressure plate 14 and are bent over toward a comparatively small-diameter functional element 8. As a result, the two clamping tabs 21a, 21b exert upon the outer wall 12 of the functional element 8 a defined clamping force that holds the functional element 8 securely in its predetermined position. The special feature of this aspect according to FIG. 4 is that the two clamping tabs 21a, 21b acting upon the same functional element 8 are arranged in mirror symmetry with respect to the geometric center axis 10 of the functional element 8, and with their free ends 22 directed toward each other at the same opening 18″ in the pressure plate 14.

[0031] The formation, or arrangement, of two clamping tabs 21c, 21d at the same opening 18″ in the pressure plate 14 is also realized in the case of another aspect, which is represented in FIG. 5. Here, the pressure plate 14 is provided with two clamping tabs 21c, 21d for the comparatively small-diameter functional element 8 assigned to the opening 18″, which are arranged with point symmetry with respect to the geometric center axis 10 of the functional element 8 and aligned parallel to each other at the same opening 18″ in the pressure plate 14.

[0032] The two illustrated aspects according to FIGS. 4 and 5 are particularly well applicable where comparatively small-diameter functional elements 8 are to be fixed by of the clamping tabs of the pressure plate 14.

[0033] While the above description constitutes the preferred embodiments of the present invention, it will be appreciated that the invention is susceptible to modification, variation and change without departing from the proper scope and fair meaning of the accompanying claims.
