Technical Field

The present invention relates to a device for mounting an air conditioning compressor on a motor vehicle body of the type defined in detail in the preamble of claim 1. The invention further relates to a motor vehicle having a vehicle body and at least two axles.

Background

A device of this type is disclosed by document DE 102009015414 a 1. With this device, the electric machine and the transmission cooperating therewith should be able to be installed in a motor vehicle as compactly and simply as possible.

An electric air conditioning compressor is usually fastened to the electric motor, for example, for which purpose an acoustic vibration decoupling is provided between the air conditioning compressor and the electric motor. The electric machine is then fastened to the body of the vehicle.

Especially when the motor is connected to the vehicle body using a four-point bearing, the powertrain bearing or the powertrain bracket takes up much space, thereby making it difficult to install the electric air conditioning compressor. This often results in the powertrain frame being necessarily severely cut. The disadvantageous installation space of the drive-train support also results in the use of a large weight in order to ultimately be able to achieve the required strength of the support.

A further significant disadvantage of the disclosed solution is that, in a series of configurations in which a vehicle with two drive axles is also possible, in a vehicle with only one drive axle, the air-conditioning compressor mounted on the non-drive axle must alternatively be connected to the motor vehicle.

Disclosure of Invention

The object of the present invention is therefore to provide a device for mounting an air conditioning compressor on a motor vehicle body, which can be used universally in various embodiments of a motor vehicle.

According to the invention, this object is achieved by the features of claim 1.

By mounting the power unit on the vehicle body by means of at least two further mounting elements, the connection rigidity of the air conditioning compressor and the connection rigidity of the mounting elements for mounting the air conditioning compressor and in particular for mounting the power unit are greatly increased.

The solution according to the invention furthermore contributes to a reduction in weight and cost, which ultimately results in a saving in fuel and in general in energy used for driving the motor vehicle. The device according to the invention also provides a particularly advantageous solution in terms of the required installation space.

In an advantageous embodiment of the invention, a particularly good support of the power unit is formed if a decoupling element is provided between the power unit and the support element.

An alternative solution to the object is given in claim 3.

By the arrangement of the retaining device on the non-driven axle of the motor vehicle and the mounting of the air conditioning compressor only on the retaining device, a very simple to implement device is formed, which reduces the weight of the motor vehicle. The solution according to the invention also makes it possible to always mount the air-conditioning compressor on the same axle in vehicles of the same series of configurations, whether or not this axle is driven.

In order to increase the rigidity of the entire system and in particular the support rigidity of the air conditioning compressor and, if necessary, of the drive unit, it can also be provided that the holding device is supported on the vehicle body on both sides of the vehicle body.

In a simplified embodiment, however, it is also possible to mount the holding device on only one side of the vehicle body.

The device according to the invention can be used very advantageously if the power means is an electric motor.

A motor vehicle having a vehicle body, at least two axles and a device according to the invention for mounting an air conditioning compressor on the vehicle body is specified in claim 7.

The device according to the invention can be used very advantageously when only one axle of the motor vehicle is driven.

In particular, the device according to the invention can be used particularly advantageously when only the rear axle of the motor vehicle is driven, since in this case the air-conditioning compressor can also be mounted on the front axle on the basis of the solution according to the invention.

The device according to the invention can also be used when at least two axles of a motor vehicle are driven.

Detailed Description

Fig. 1 shows a first embodiment of a motor vehicle 1 having a vehicle body 2 and two axles 3 and 4, namely a front axle 3 and a rear axle 4. The driving direction "x" of the motor vehicle 1 is illustrated in all the figures by means of the correspondingly illustrated arrow. In the exemplary embodiment shown in fig. 1, both axles 3 and 4 are driven, i.e., a four-wheel-drive motor vehicle 1 is used here. The first power unit 5 is provided for driving the front axle 3, and the second power unit 6 is provided for driving the rear axle 4. In this case, the two power units 5 and 6 are each an electric motor. In addition, an air conditioning compressor 7 is mounted in the motor vehicle 1 and by means of a device 8 described in detail below, which is thus used to mount the air conditioning compressor 7 on the body 2 of the motor vehicle 1. The device 8 is assigned to the front axle 3.

Fig. 2 shows a further embodiment of the motor vehicle 1. The motor vehicle, such as the motor vehicle 1 of fig. 1, has a vehicle body 2, a front axle 3 and a rear axle 4. In this case, however, only the rear axle 4 is driven by the second drive 6, whereas the first drive 5 applied to the front axle 3 in fig. 1 is not present. However, the air conditioning compressor 7 is supported on the vehicle body 2 by means of the device 8 also present here, wherein the retaining device 9 is arranged on the non-driven front axle 3 and only the air conditioning compressor 7 is mounted on the retaining device 9. The device 8 can be designed for this purpose in principle identically to the device 8 of fig. 1. Since the first power means 5 is not present in the embodiment of fig. 2, a defined connection position between the device 8 and the first power means 5, which is not described in detail with reference to fig. 2, can be dispensed with.

The air conditioning compressor can thus be installed in motor vehicles of the same series of configurations always on the same axle 3 or 4, whether or not the axle 3 or 4 is driven. In the illustrated embodiment, the device 8 is associated with the front axle 3. However, it is also possible to assign the device 8 to the rear axle 3 accordingly. This applies in particular, but not exclusively, to the case in which only the front axle 3 of the motor vehicle 1 is driven.

Different embodiments of the device 8 are shown very schematically in fig. 3 to 6. The first power unit 5 is correspondingly located on the front axle 3. However, in any of the embodiments of the device 8 described below, as can be seen analogously from a comparison of fig. 1 and 2, the mounting of the first power unit 5 on the device 8 can be dispensed with without problems.

Fig. 3 shows the embodiment of the device 8 shown in fig. 1 for mounting an air conditioning compressor 7 on a body 2 of a motor vehicle 1. The device 8 has a holding device 9, which supports the body 2 of the motor vehicle 1, which is only shown in a simplified manner in fig. 3, by means of two support elements 10 and 11. The connection between the supporting elements 10 and 11 and the body 2 is also only schematically shown here. In the embodiment of fig. 3, the holding device 9 is supported on the vehicle body 2 on both sides thereof. The air conditioning compressor 7 is mounted on the holding device 9. Furthermore, a first drive unit 5 is mounted on the retaining device 9, which serves to drive the front axle 3 of the motor vehicle 1. On the side opposite the holding device 9, the first power unit is supported on the vehicle body 2 by means of two further support elements 12 and 13. The connection between the support elements 10 and 11 and the body 2 is also only schematically shown here. In order to achieve a vibration decoupling of the first drive unit 5 from the body 2, respective decoupling elements 14 and 15, which may also be designated as motor supports, are provided between the first drive unit 5 and the two support elements 12 and 13.

An alternative embodiment of the device 8 is shown in fig. 4. The holding device 9 is supported on one side of the vehicle body 2 only, and also by means of two support elements 10 and 11. The first power unit 5 is then supported on the other side of the body, for which purpose two support elements 12 and 13 are again used. As in the embodiment of fig. 3, two decoupling elements 14 and 15 are also provided here between the first drive means 5 and the support elements 12 and 13. On the holding device 9, the air conditioning compressor 7 is arranged on one side and the first power unit on the other side.

Since the support elements 10 and 11 as well as the support elements 12 and 13 and the decoupling elements 14 and 15 connected thereto in each of the embodiments described here in principle assume the same function and are only mounted in different positions, these elements can also be designated by different, corresponding reference numerals.

In the embodiment of the device 8 according to fig. 5, the first power unit 5 or the air conditioning compressor 7 is exchanged for the embodiment of fig. 3 on the side of the mounting on the holding device 9. This can be advantageous, for example, because of the existing construction space. In addition, the holding device 9 is also supported on both sides of the vehicle body 2 by means of two support elements 10 and 11. As described above, the first power unit 5 and the air conditioner compressor 7 are mounted on the holding unit 5. The first power unit 5 is supported on the vehicle body by means of the support elements 12 and 13, wherein decoupling elements 14 and 15 are also provided here.

The embodiment shown in fig. 6 is in principle a mirror image of the embodiment in fig. 4, i.e. the holding device 9 is supported on only one side of the vehicle body 2, while the first drive unit 5 is supported on the other side of the vehicle body 2.

The holding device 9 and its connection points 16 to the supporting elements 10 and 11 can be seen in detail in fig. 7. At these connection points 16, which are preferably designed as elastic bearings, the support elements 10 and 11 and thus the retaining device 9 can thus be mounted on the vehicle body 2. Furthermore, a connection point 17 for mounting the air conditioning compressor 7 on the holding device 9 is shown. The connection point may be, for example, a rubber element with a threaded sleeve, whereby a slight movement of the air conditioning compressor is achieved. The decoupling formed in this way achieves an acoustic advantage, since fewer interfering frequencies occur. This, together with the connection point 7, results in a double acoustic decoupling of the air conditioning compressor. Finally, fig. 7 also shows a plurality of attachment points 18 for attaching the first power unit 5 to the holding device 9. The holding device 9 is preferably rigidly connected to the power means 5, which increases the rigidity of the entire system or of the entire apparatus 8.
