Definitions
- the invention relates to a housing according to the independent claim 1.
- the space for a single component is limited due to the large number of components and units. This is especially true for the internal combustion engine.
- the cover of a housing of a gearbox control unit which is arranged in the gearbox itself, must not raise and lower indefinitely due to the temperature and pressure fluctuations prevailing there. At low pressure, electronic components on the transmission control unit could be damaged. With overpressure and the associated outward buckling of the lid could be sensitive components in the vicinity of the housing affected.
- an aluminum lid is more expensive than, for example, a plastic lid.
- the lifting and lowering of the lid must be limited by an additional measure.
- an additional screw can be screwed from the outside through an opening in the lid into a corresponding thread in the lower housing part and thereby limit the height clearance of the lid.
- the night part is that the opening in the lid must be additionally sealed against surrounding medium such as gear oil.
- the invention has for its object to provide a housing with a housing cover made of plastic of the type mentioned above, which limits the lifting and lowering of the housing cover simple, reliable and with little effort.
- This object is achieved by a housing with the features of claim 1.
- the essence of the invention is that at least one device is provided which connects the housing cover in the Mitteribe- rich with the lower housing part in addition positively and non-positively.
- a part of the device is non-positively connected to the lower housing part.
- this part is designed so that it is screwed or clamped in the lower housing part.
- the other part of the device is in particular non-positively and positively connected to a locking device on the housing lower part facing side of the housing cover. If the frictional connection between the device and the latching device becomes lower due to thermal loads, the lifting and lowering of the housing cover is advantageously still prevented by the positive connection between the device and the housing cover.
- the part of the device which is connected to the latching device of the housing cover designed as a cylinder with a nearly centrally encircling groove for receiving the latching lug of the latching device.
- the circumferential groove in the cylindrical part of the device and the latching device with the latching lug are configured so that the latching lug in pressure and / or temperature fluctuations in the housing, the expansion of the housing cover in the direction of the housing base and in the opposite direction, the means the lifting and lowering of the housing cover, limited.
- the dimension of the latching lug in the latching device in the direction of the longitudinal axis of the cylindrical part of the device is smaller than the diameter of the groove in the cylindrical part of the device.
- the diameter of the cylindrical part of the Vorrich- device is slightly larger than the inner diameter of the locking device, so that after pressing the cylindrical member into the locking device a frictional connection between the cylindrical part and the locking device. If there is a slight lateral offset between the latching device in the housing cover and the device for connecting the housing cover to the housing lower part, this causes an additional preload after latching, thereby increasing the adhesion.
- the housing cover in the middle region, ie in the region of the latching device, which is part of the connection between the housing cover and the housing base, closed.
- this type of connection does not have to be sealed off against a surrounding medium.
- FIG. 1 shows a section through the connection of a housing cover with a housing lower part
- FIG. 2 shows an elevation of a housing in the middle region of a housing cover.
- Fig. 1 shows a section through the connection of a housing cover 1 with a housing lower part 2.
- the device 3 is designed here as a cap screw.
- the lower part 5 of the device 3 is screwed into the lower housing part 2 and thus connected non-positively with the lower housing part 2.
- the upper part 6 of the device 3 is in particular cylindrical.
- a radial circumferential groove 8 serves to receive the latching lug 9, which is a part of the latching device 7.
- the latching device 7 is preferably molded onto the housing lower part 2 facing side of the housing cover 1.
- the diameter Dl of the groove 8 is in particular larger than the dimension of the latching lug 9 in the direction of the longitudinal axis L of the cylindrical part 6.
- the diameter D2 of the cylindrical part 6 is slightly larger than the inner diameter D3 of the locking device 7, so that after pressing the locking device 7 in the cylindrical part 6, a frictional connection between the part 6 and the locking device 7 is.
- the case may occur that the frictional connection between the cylindrical part 6 and the rat device 7 becomes smaller or completely disappears.
- the positive connection of groove 8 and detent 9 prevents unlimited lifting and lowering of the housing cover 1.
- the degree of lifting and lowering of the housing cover 1 corresponds to the game of locking lug 9 in the groove 8 in the direction of the longitudinal axis L.
- the Diameter of the latching device 7 in the region of the latching lug 9 greater than the diameter of the cylindrical part 6 in the region of the groove 8.
- a circuit board 10 which is used in particular for receiving electronic components, positively connected to the lower housing part 2.
- FIG. 2 shows an elevation of a housing consisting of a housing cover 1 and a housing lower part 2.
- the housing cover 1 is in its middle region 4 by means of the device 3 positively and non-positively connected to the housing lower part 2.
