[0002]

2. Description of the Related Art An axial piston machine of this kind is known from DE 35 45 428 A1. This axial piston machine is used as an additional hydraulic drive motor for the steerable front wheels of a rear drive vehicle. In contrast to other wheel drive designs, this axial piston motor is not spatially separated from the wheel suspension in its arrangement. Rather, the individual components enter and exit each other to save space.

[0003]

It is an object of the present invention to provide an axial piston machine of the type described at the outset which is structurally simple.

[0004]

According to the invention, this object is achieved, according to the invention, by incorporating a cylinder drum into a driven part.

[0005] Advantageous configurations of the invention are set out in the further claims.

[0006]

The axial piston machine according to the invention has a small number of parts, which makes it easy to manufacture and assemble. Moreover, the axial piston machine has compact dimensions.

The axial piston machine according to the invention has only two main components: a stationary support and a rotatable driven part. The stationary support includes a swash plate, pressure medium supply and control means, a wheel axle (in the embodiment as a wheel motor), and a device for compensating the axial force generated by the piston (in other words, the cylinder). The axial force acting on the drum remains inside the support), a brake with operating means and means for suspension on the frame of the vehicle. The rotating driven part is arranged between a cylinder drum, a piston of an axial piston machine, a centering means and a screw hole for rim assembly (in a configuration as a wheel motor) and a shaft journal and a driven part. And a compensating surface for axial force compensation and a receiver for packing.

In terms of manufacturing technology and assembly technology, it is advantageous that the cylinder drum is formed integrally with the driven part.

It is advantageous if the cylinder drum is provided with a support portion common to the driven portion on the support portion. Compared to axial piston machines known from the prior art, it is possible to dispense with a specific support for the support of the cylinder drum at the support.

In order to obtain as wide a bearing spacing as possible, according to an advantageous further development of the invention, two angular rolling bearings are provided in the O-arrangement for bearing the driven parts on the support in an O-arrangement. Are located in

In this case, it is advantageous if the inner peripheral surface of the cylinder drum is provided with a receiving hole for an angular rolling bearing. In addition, it is possible that the outer ring of the angular rolling bearing is formed integrally with the inner peripheral surface of the cylinder drum.

An axial piston machine according to the invention, as is well known, comprises a bore in a cylinder drum and a piston which moves longitudinally in the bore. Each of these pistons is engaged with a stroke plate by a slide body.
In a further advantageous embodiment of the invention, the stroke plate is arranged in the region of the base body of the support, and the control means for the supply of pressure medium to the bore is provided in the axial dimension of the stroke plate and the cylinder drum. Is located within. This results in reduced axial space requirements.

According to a particularly advantageous embodiment of the invention, the support means (15) for guiding the axial force acting on the cylinder drum to the support part bypassing the rolling elements of the angular rolling bearing. It has. In this case, the axial force is not guided through the rolling elements of the angular rolling bearing but rather through the compensating device to the support.

Therefore, the angular rolling bearing between the cylinder drum and the shaft journal is only capable of absorbing externally applied forces acting on the driven part, in particular, wheel loads and radial drive mechanism forces. It is enough if it has the size.

For reasons of space, it is advantageous to arrange the compensator axially between the angular rolling bearings.

A compensating device having a pressure chamber for receiving a supply of pressure medium from the high pressure side of the axial piston machine;
A first pressure surface which is arranged corresponding to the support portion and which acts in a direction opposite to the direction toward the stroke plate;
Advantageously, a second pressure surface is provided which is arranged corresponding to the cylinder drum and acts in the direction toward the stroke plate. The compensator therefore corresponds in principle to a hydrostatic thrust bearing in its operation.

A first pressure surface (17a) is arranged on a ring piston arranged on the axle journal, which ring piston has an axial direction on the axle journal in a direction opposite to the direction toward the travel plate. It is effective if movement is blocked.

A second pressure surface is integrally formed with the second ring piston, and the ring piston is indirectly or directly applied to the rotating cylinder drum while the load is statically reduced by the compensation surface. It is effective to be in contact. This simplifies the pressure chamber seal, which would be complicated if the second pressure surface were rotating.

Advantageously, the pressure chamber is connected to the outlet of the shuttle valve, the first inlet of the shuttle valve being connected to the high pressure side of the axial piston machine and the second inlet of the shuttle valve being connected to the low pressure side. It is. This assures that the pressure chamber receives a constantly supplied high pressure from the high pressure side of the axial piston machine formed according to the invention, irrespective of which machine side supplies the high pressure.

As long as the axial piston machine according to the present invention is configured as a constant displacement machine, the stroke plate is formed integrally with the base body of the supporting portion.
Further simplification is obtained with respect to fabrication and assembly.

[0021] In this case, according to a particularly advantageous configuration of the invention, control means for the supply of pressure medium to the bore are integrated in the stroke plate.

In this case, a control surface having a kidney-shaped control port is provided on the stroke plate, and a slide plate that rotates in synchronization with the cylinder drum is disposed between the control surface and the slide body. In order to supply the pressure medium to the holes in the cylinder drum, passages are provided in the piston, the slide body, the slide plate and the stroke plate.

According to yet another advantageous configuration of the invention,
Control means for the supply of the pressure medium to the bore are integrated in the compensator.

This simply means that the pressure chamber is divided radially into two parts, in which case the first pressure chamber is connected to the high-pressure side of the axial piston machine and the second pressure chamber A chamber connected to the low pressure side, in which case a renal shaped control port located radially outward in the compensation plane;
A renal-shaped compensation port located radially inward is disposed, and the renal-shaped control port and the renal-shaped compensation port cross each other and are connected to the pressure chamber. This is achieved by the fact that the connection passage to the hole is opened in the rotating opposing surface of the cylinder drum.

As long as the second ring piston is repelled by the spring force toward the opposing surface of the cylinder drum, the compensating surface is kept in contact with the rotating opposing surface of the cylinder drum by the kidney-shaped control port even if the pressure is low. Abut

According to the above-mentioned control means incorporated in the compensating device, it is possible to simply form a variable displacement axial piston machine according to the invention.

In this case, it is advantageous if the adjusting device for the adjustable travel plate and the support are arranged in the base of the support.

In order to further reduce the size of the axial piston machine, the slides are formed from spherically segmented lenses.

As long as each of the pistons is repelled toward the travel plate by a spring located in the bore,
No special piston holding device is required, and the structure is reduced.

If the axial piston machine according to the invention is embodied as a wheel motor, the driven part has at least one wheel rim for receiving the rim centering means for assembling the wheel rim. And a screw hole.

As long as the screw holes are at least partially arranged between the holes of the cylinder drum, the radial space requirements are reduced. Therefore, the axial piston machine according to the present invention provides a wheel for a small rim in which the hole circle diameter of the rim (the diameter of the circle in which the hole is arranged) corresponds to the pitch circle diameter of the screw hole of the driven part. Can be used as a motor.

Furthermore, it is advantageous if a brake, in particular a spring-loaded multi-disc brake, is arranged between the supporting part and the driven part.

In this case, it is effective if the brake operating device is arranged in the support. Since the support portion is fixed, a rotary portion penetrating guide (rotary transmission lead-through) is not required, so that pressure supply for operating the brake operating device by the pressure medium is simple.

A brake multi-disk support is connected to or formed on the driven part and is provided on the outer peripheral surface of the cylinder drum on the side of the cylinder drum closer to the stroke plate. The simple arrangement of the multi-disc brake according to the first embodiment of the invention is obtained by being arranged in the region of the bore that extends axially towards the stroke plate at the opening of the bore.

A brake multi-disc support is connected to or formed on the support and, together with the brake operating device at the end of the shaft journal remote from the stroke plate, is mounted on the cylinder drum. Access to the brake for maintenance and service purposes is improved as long as the brake device is configured to be located in an axially continuous area.

The cylinder drum has a radial flange adjacent to the stroke plate, and the radial flange is
It is located axially inside the bush-like axial projection of the support, in which case sealing means, especially a shaft seal ring, is provided between the radial flange and the axial projection in the radial direction. As a result, the axial piston machine according to the invention is easily sealed to the outside. In this case, the axial projection serves as a receptacle for the sealing means.

In the arrangement of the axial piston machine according to the invention as a wheel motor, it is advantageous if the support is provided with a device for fixing to a structural part fixed to the vehicle.

According to an advantageous solution in terms of manufacturing costs and fixing reliability, the device is formed as a ring flange with coaxial holes.

It is particularly advantageous if the stroke plate is formed as a multi-stroke plate. Thereby, a large suction capacity of the axial piston machine is obtained.

A wheel motor of this kind can therefore be designed as a low-speed engine if the dimensions are appropriate. Thus, one or more stages of transmissions arranged behind the hydraulic motor to reduce the output speed, which are usually required when an axial piston machine is used as a wheel motor, are eliminated.

[0041]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The advantages and details of the present invention will now be described in detail with reference to the illustrated embodiment.

The axial piston machine according to the invention is designed as a wheel motor in the embodiment shown.
This axial piston machine mainly consists of a stationary support 1
And a driven part 2 that rotates. The support has a base body 3 with an integrally formed travel plate 4 and a shaft journal 5. The shaft journal 5 and the base 3 are preferably formed integrally with one another. The stroke plate 4 can also be formed as a multi-stroke plate.

The cylinder drum 7 is supported on the shaft journal 5 via two O-shaped angular rolling bearings 6a, 6b formed as conical rolling bearings. For this purpose, the inner peripheral surface of the cylinder drum 7 is provided with receiving holes for the angular rolling bearings 6a, 6b. The cylinder drum 7 is incorporated in the driven part 2. In the present embodiment, the cylinder drum 7 consists of the same parts as the driven parts 2 and therefore has only one common bearing part. The bearing therefore forms a wheel bearing and a bearing for the cylinder drum 7.

The cylinder drum 7 has holes 8 and a piston 9 which can move longitudinally in these holes. The piston 9 is spring-biased toward the travel plate 4 and is formed as a ball-segment lens.
0 is supported on the stroke plate 4. The stroke plate 4 has a control surface 12 with renal control ports 11a, 11b. A slide plate 13 that rotates with the cylinder drum 7 in synchronization with the rotation is disposed between the stroke plate 4 and the slide body 10.

In order to supply a pressure medium from the kidney-shaped control ports 11a and 11b to the hole 8 of the cylinder drum 7, a passage is provided in the piston 9, the slide body 10 and the slide plate 13. The kidney-shaped control ports 11a, 11b communicate with a passage in the base 3, which opens into a supply connection 14 (see FIG. 2) arranged on the outer end face of the base 3.

The axial force acting on the rotating cylinder drum 7 caused by the supply of the high-pressure medium to the hole 8 causes the stationary force to pass through, for example, the left-hand angular rolling bearing 6a in FIG. It is transmitted to the support 1. However, this requires a properly dimensioned bearing.
In order to avoid such a flow of force, a compensating device 15 for guiding the axial force acting on the cylinder drum 7 to the support portion 1 is disposed between the angular rolling bearings 6a and 6b.

The compensator 15 has a pressure chamber 16 which receives a supply of pressure medium from the high-pressure side of the axial piston machine. This pressure chamber is composed of a first ring piston 17 disposed on the shaft journal 5 and a second ring piston 17. Is located between the ring piston 18 and the ring piston 18. The first ring piston 17 has a first pressure surface 17a which is located corresponding to the support portion 1 and acts in a direction opposite to the direction toward the stroke plate 4, and is leftward in FIG. In short, the first ring piston abuts on the angular rolling bearing 6a far from the stroke plate, thereby preventing the axial movement of the first ring piston in this direction. The second ring piston 18 is located corresponding to the cylinder drum 7,
It has a second pressure surface 18a acting in the direction toward the stroke plate 4 and a compensation surface 18b, by means of which the second ring piston abuts against the rotating annular surface 7a in a statically lightened state. . In this embodiment, the annular surface 7a is formed by an intermediate portion 7b non-rotatably connected to the cylinder drum 7.

In order to keep the pressure chamber 16 always connected to the high pressure guide side of the axial piston machine, the pressure chamber 1
6 is connected to the outlet of the shuttle valve 19 (see FIG. 2), a first inlet 19a of the shuttle valve is connected to the high pressure side of the axial piston machine and its second inlet 19b is connected to the low pressure side. .

The driven portion 2 (cylinder drum 7) is provided with rim centering means 20 for mounting the wheel rim and a screw hole 21 for receiving the wheel rim. In order to obtain the smallest possible pitch circle diameter, the screw holes 21 are arranged at least partially between the holes 8 of the cylinder drum 7.

A brake 22 formed as a spring energy storage type multi-disc brake is disposed between the support portion 1 and the driven portion 2. An attached piston-like brake operating device 23 provided for releasing the brake is located in the base 3 of the support 1.

The spring storage type multi-disc brake is provided with a brake multi-disc support 24, which in this embodiment is the driven part 2
(Cylinder drum 7) and is formed on the outer peripheral surface of the cylinder drum 7 on the side closer to the stroke plate 4, also at the opening of the hole 8, and continues axially in the direction of the stroke plate 4. Are arranged in the region.

A radial flange 25 is arranged on the cylinder drum 7 adjacent to the stroke plate 4, and this radial flange is a bush-like axially projecting portion 26 of the support 1.
Is located axially inside. This axial projection 25
Helps to receive the shaft seal ring 27.

For the purpose of fixing an axial piston machine formed as a wheel motor, the base 3 of the support 1 is provided with a ring flange 28 with a coaxial hole 29 at a component fixed to the vehicle. .

The arrangement of the ring flange 28 is shown in FIG. A brake connection hole 30 for the brake operation means 23 and a tank connection hole 31 are provided at the upper end of the base.

The embodiment of the invention shown in FIG. 3 differs from the embodiment shown in FIGS. 1 and 2 in that the control means is not provided on the stroke plate, It is built into.

As a result, a first pressure chamber 16a connected to the high-pressure side of the axial piston machine via the hole 160a and a second pressure chamber 16b connected to the low-pressure side via the hole 160b are formed. Inside the compensating surface 18b corresponding to the control surface 12, there are externally located renal shaped control ports 11a, 11b cross-connected to the pressure chambers 16a and 16b and radially inwardly located renal shaped compensation ports. Ports 32a and 32b are arranged (for this, see FIG. 4).

Thus, the renal shape control port 11a and the renal shape compensation port 32b are connected to the hole 160a, and the renal shape control port 11b and the renal shape compensation port 3 are connected on the other side.
2a is connected to the hole 160b. Renal control port 1
Since 1a and 11b are provided for supplying the pressure medium to the hole 8 of the cylinder drum 7, it is necessary to flow a large amount of pressure medium, and the kidney-shaped compensation ports 32a and 32b are provided on the other surface. The renal shaped compensation ports 32a, 32b are connected to the pressure chambers only because they serve only to define a defined axial force, and it is sufficient to create a small amount of pressure medium and maintain the compensation pressure. 16a, 1
The connection is made such that the renal shaped control ports 11a, 11b are connected to the pressure chambers 16a, 16b via passages 33a, 33b having a larger cross section than the passages 34a, 34b serving to connect to the pressure chambers 16a, 16b. .

A connection passage 35 to the hole 8 is opened in the rotating facing surface 70 of the cylinder drum 7 so as to face the kidney-shaped control ports 11a and 11b. This facing surface 70 cooperates with the renal control port to help control the axial piston machine according to the present invention. This opposing surface 70 also receives a defined axial force generated by the compensating device 15 and thus the rotating annular surface 7a of the embodiment of FIG.
It has a function corresponding to.

Even when the pressure is low, the renal-shaped control port 11
a so that the compensation surface 18b provided with the first and second ring pistons 1a and 11b abuts the facing surface 70 of the cylinder drum 7.
Reference numeral 8 is repelled by a spring toward the cylinder drum 7.

The embodiment shown in FIG. 5 differs from the axial piston machine of the embodiment shown in FIG. 3 in that the arrangement of the shaft seal ring 27 in the region of the base 3 of the support 1 is not changed and the brake 22 Is located at the end of the shaft journal remote from the swash plate, also in the region axially following the cylinder drum 7.

In this case, the brake multi-disk support 24a is non-rotatably connected to the shaft journal 5 of the support 1. The piston-like brake actuating device 23 is preferably spring-loaded by a disc spring. The supply of the pressure medium necessary for the release of the energy-storing multi-disc brake is provided by a passage 37 formed in the shaft journal 5. An advantage of the described arrangement is that the brake 22 is easily accessible for maintenance and service purposes. The axial piston machine according to the invention does not need to be disassembled for that.

The embodiment shown in FIG. 6 differs from the embodiment shown in FIG. 5 in that the stroke volume can be adjusted. For this purpose, an adjusting device 38 for the adjustable travel plate 4 a and a support 39 are arranged in the base body 3 of the support 1.
