Description

Technical Field

[0001] The present invention relates to a housing for a vehicle, wherein the housing is configured, in particular, to accommodate transmission components and to have external devices. Background Technology

[0002] As is well known, vehicle housings typically house, for example, transmissions or drive motors. Such housings serve as enclosures for equipment and components within the internal space. If additional equipment is located outside the housing, it is generally protected by an additional enclosure.

[0003] For example, document EP2577107B1 discloses a hybrid drive module with a housing and a drivetrain component housed within its internal space. Summary of the Invention

[0004] The object of the present invention is to improve the housing for vehicles, wherein in particular, the protection of equipment arranged on the outer side of the housing should be optimized. Furthermore, the housing should be compact in construction. The above object is achieved by the features of independent claim 1. Advantageous embodiments are described in the subject matter of the dependent claims, the following description, and the drawings.

[0005] According to a first aspect, a housing for a vehicle is provided, the housing comprising: an outer surface having an inwardly oriented recess formed in a section of the outer surface configured as a bottom side; a device disposed in the recess on the outer surface of the housing and connected in fluid communication with an internal space of the housing; and a first protective rib and a second protective rib disposed in a region of the recess on the outer surface and positioned laterally to the device, wherein the two protective ribs project radially to protect the device. The term "positioned laterally" means that the protective ribs are arranged on both sides of the device and the device is spatially arranged between the two protective ribs.

[0006] The housing and the equipment fixedly connected to its outer surface form a pre-assembled unit. Preferably, the vehicle's transmission components are arranged within the internal space of the housing. For example, a clutch actuator and / or a drive motor, preferably a motor with a reduction gearbox, are arranged within the internal space of the housing. Furthermore, the internal combustion engine on the drive side of the housing is drivably connected to the shift transmission on the driven side of the housing via a drive shaft.

[0007] The recess on the outer surface of the housing points inward and is at least partially provided for accommodating the device. Thus, the device is at least partially inserted into the recess, which is configured to be concave, thereby at least partially protecting the device without occupying a large portion of the internal space of the housing.

[0008] To further improve equipment protection, two radially projecting protective ribs are arranged in a recessed area on the outer surface. These two ribs are positioned laterally on the side of the equipment and primarily serve two protective functions: protecting the equipment from loads, especially supporting forces, when the housing is placed during assembly or maintenance; and protecting the equipment from stone impacts while the vehicle is in motion. This is because the equipment is positioned on the underside of the housing, i.e., on the outer surface facing downwards towards the road surface, where the radially projecting protective ribs reliably protect the equipment. The equipment does not protrude to the side or upwards of the vehicle, thus allowing the housing to be constructed particularly compactly. This housing is particularly suitable for heavy-duty trucks with a frame structure.

[0009] According to one embodiment, the two protective ribs are substantially parallel and identical in construction, extending along the longitudinal direction of the housing. This encloses the recesses and equipment on two opposing sides, thereby providing not only a reliable support surface for the housing but also protection from stone impacts and water splashes from the sides.

[0010] According to one embodiment, the two protective ribs are constructed to extend obliquely in the radial direction. In other words, the two protective ribs are constructed in a sloping manner in the longitudinal direction of the housing, thereby allowing the housing to be placed in an oblique manner, wherein preferably the housing can be supported at additional support points when placed. In particular, the device is screwed to the housing in an oblique manner. The oblique angle of the device substantially corresponds to the oblique angle of the sloping protective ribs. This further improves protection against stone impacts and water splashes from the side.

[0011] According to one embodiment, a third protective rib is arranged transversely to and connected to the two protective ribs. Specifically, the three protective ribs form an open casing with one side open on one of the four sides of the device. Therefore, the protective ribs extend along three of the four sides of the device. Preferably, the side of the device opposite to the direction of travel remains open. Constructing three protective ribs on the casing further enhances protection against stone impacts and water splashes, and provides a good compromise for easy assembly and maintenance of the device arranged on the casing surface.

[0012] According to one embodiment, the housing has a generally cylindrical base shape, wherein recesses are arranged on the outer surface configured as circumferential surfaces. For example, the housing may be of a multi-piece construction and closed at least on one or both end sides with corresponding housing covers.

[0013] According to one embodiment, at least one protective plate for covering the device is detachably connected to at least one of the protective ribs, particularly to the first two or all three protective ribs.

[0014] For example, a protective plate is bolted to the protective ribs at three or four points to ensure good retention. The protective plate preferably extends across the entire device and is configured so that the traveling wind can reliably carry away splashing water.

[0015] According to one embodiment, at least one protective plate, together with at least one protective rib, constitutes a labyrinth seal. For example, the side of the protective plate extends along the protective rib to form an air gap, the width and length of which are set to make it difficult or impossible for dirt and splashed water to enter.

[0016] According to one embodiment, the device is configured as a fluid pump for supplying lubricant and coolant to the interior space of the housing. The fluid pump preferably delivers lubricating oil and coolant from an oil pan within the housing to the clutch actuator, via a shaft to the bearing and gear regions, and / or to the motor, in order to dissipate heat therefrom.

[0017] According to a second aspect, a vehicle having the housing described in the first aspect is provided. The definitions and statements above regarding the technical effects, advantages, and preferred embodiments of the housing according to the invention are also applicable by analogy to the vehicle according to the invention. The vehicle is preferably configured as a truck. Attached Figure Description

[0018] Advantageous embodiments of the present invention will now be described with reference to the accompanying drawings, wherein the same or similar elements are given the same reference numerals. In the drawings: Figure 1 A highly simplified schematic diagram of a vehicle according to the invention, with a housing according to the invention, is shown; Figure 2 A schematic diagram of the rear side of the housing is shown; Figure 3 A schematic diagram of the bottom side of the casing is shown; Figure 4 A cross-sectional schematic diagram of the casing is shown; Figure 5 A partial cross-sectional schematic diagram of the housing according to the second embodiment is shown. Detailed Implementation

[0019] Figure 1 A simplified diagram of a vehicle configured as a truck 100 is shown. The vehicle 100 has a first drive motor 10 configured as an internal combustion engine, a second drive motor 9 configured as an electric motor, and a shift transmission 12, all operatively connected to the drive wheels 13 of the vehicle 100. Therefore, this truck is configured as a hybrid vehicle. The electric motor 9 is arranged in a housing 1, which is described in detail below.

[0020] Figure 2 It shows Figure 1 The back side of the casing 1 shown. From Figure 2 As can be seen, the housing 1 has a generally cylindrical basic shape, and the device 3 is arranged on the bottom side of the outer surface of the housing 1, which is constructed as a circumferential side. The device 3 is arranged in a recess (not visible in this figure) on the outer surface and is connected to the internal space of the housing 1 in a fluid-conducting manner. In particular, the device 3 is configured as a fluid pump for supplying lubricant and coolant to the internal space of the housing 1. The fluid pump preferably delivers lubricant and coolant from an oil pan in the internal space of the housing 1 through a shaft to lubricate the bearings and gear areas of the reduction gearbox and cool the motor arranged in the rear area of ​​the housing 1. An electrical interface 14 for the motor is also arranged on the outer side of the housing 1. To protect the device 2, a first protective rib 4, a second protective rib 5, and a third protective rib 6 are arranged on the outer surface in the area of ​​the device 3. The protective ribs 4, 5, and 6 are positioned on the sides of the device 3 from three sides, thereby protecting the device 3 from stone impacts and water splashes.

[0021] Figure 3 It shows Figure 2 The bottom side of the casing 1 shown. From Figure 3 As can be seen, the first protective rib 4 and the second protective rib 5 are substantially parallel and identical in construction, extending in the longitudinal direction of the housing 1. The third protective rib 6 is arranged transversely to and connects to the two protective ribs 4 and 5. All three protective ribs 4, 5, and 6 are positioned on the side of the recess 2 where the equipment 3 is located. The combination of the recess 2 with the protective ribs 4, 5, and 6 on three of the four sides achieves a good compromise between sufficient protection against stone impacts and water splashes and ease of assembly and maintenance. Furthermore, this makes the housing 1 particularly compact.

[0022] Figure 4 It shows Figure 2 and Figure 3 The cross-sectional view of housing 1 shown. From Figure 4 It can be seen that the two identical protective ribs (only the second protective rib 5 is visible in this figure) are constructed with an inclined extension in the radial direction. In other words, the two protective ribs 5 are constructed with a ramp shape in the longitudinal direction of the housing 1, thereby allowing the housing 1 to be placed in an inclined manner. In addition, the device 3 is also screwed into the recess 2 of the housing 1 in an inclined manner, wherein, Figure 3 Four screw-on devices 16 are visible on device 3 for this purpose. The tilt angle of device 3 basically corresponds to the tilt angle of the protective rib 5, which has a sloping structure. This further improves protection against stone impacts and water splashes from the side. Figure 4 It can also be seen that the motor 9 is arranged in the rear section of the housing 1, while the clutch actuator 8 is arranged in the front section of the housing 1. The clutch actuator 8 has a hollow shaft-shaped section for accommodating the drive shaft (not shown in detail).

[0023] Figure 5The figure shows a portion of a second embodiment of the housing 1. The second embodiment of the housing 1 essentially corresponds to the first embodiment, with the only difference being the provision of a protective plate 7 for covering the device 3. The protective plate 7 is detachably connected to the housing 1 via four screwed devices (not shown in detail), which screw into threaded holes 15 provided for this purpose on the protective ribs 4, 5, and 6. Figure 3 (As shown). In Figure 3 In the first embodiment of the housing 1 shown, these threaded holes 15 are also present, through which subsequent installations can be made. Figure 5 The protective plate 7 is shown. The protective plate 7, together with the third protective rib 6, forms a labyrinth seal 11, thereby further improving protection against stone impacts and water splashes.
