Definitions
- the invention relates to an oil-carrying shaft according to the preamble of independent claims 1 and 7.
- Shafts are known in many areas of technology, through whose axial bore a liquid or gaseous medium can be passed. Such shafts are also used in particular in transmissions where it is important to conduct a hydraulic oil under pressure from a control pressure source to a transmission component to be actuated with this control pressure medium, as space-saving as possible.
- Transmission components of this type are generally piston-cylinder arrangements with which clutches or brakes of the transmission can be actuated, or with which the distance between conical disks of a continuously variable belt transmission can be adjusted to change the transmission ratio.
- two or more axial bores arranged in parallel next to one another can also be provided in the shaft according to the prior art.
- the control pressure medium can be fed into and removed from the axial bores at the ends of the axial bores and / or via radial bores in the shaft, which are fluidically connected to the axial bores.
- the control pressure medium in the different lines generally having different control pressures.
- a hollow cylindrical tube is inserted into a preferably coaxial bore of the shaft, which tube forms a first pressure medium line with its axial cavity ,
- a further pressure medium line is also created, which is connected in terms of printing technology to the actuators mentioned at the beginning, with generally radially oriented feed or discharge bores.
- a primary shaft of a continuously variable belt transmission with an axial bore is known, for example, from DE 199 21 750 AI, into which a tube which is rotationally sealed against this axial bore and which itself has two longitudinal bores is inserted.
- a secondary shaft of a continuously variable belt transmission is known from DE 196 03 598 AI, in which a tube inserted into an axial bore of this shaft is fixed with one end in the transmission housing in a rotationally fixed manner, while the other tube end is in one slide bearing arranged in the axial bore is mounted.
- the hollow cylindrical interior of the tube serves as the first control pressure line, while a cylindrical annular space formed between the outside diameter of the tube and the inside diameter of the axial bore forms a second control pressure line.
- US Pat. No. 6,015,359 A discloses a secondary shaft of a continuously variable belt transmission with an axial bore, in which a special plug is firmly inserted.
- This stopper divides the secondary shaft axial bore into two chambers, the stopper itself being supplied centrally with a control pressure medium via a tube likewise inserted into the axial bore.
- This control pressure medium which is under high pressure, can be conducted via three radial plug bores and a radially outer annular gap into associated radial secondary shaft bores.
- three small axial bores are formed in the stopper, which connect the two aforementioned chambers with one another in terms of flow technology.
- the oil-carrying shaft has a shaft interior which is coaxial or axially parallel to the shaft longitudinal axis, and a means arranged in this shaft interior for dividing the shaft interior into at least two oil-conducting channels which are separate from one another.
- the channels are designed as channels which are initially open along their longitudinal extent (similar to axial grooves) on the inner wall of the shaft and are separated from one another and sealed off from one another by a tube inserted into the shaft interior.
- the open channels of the shaft are formed by bores which overlap in terms of their cross-sectional geometry. These open channels can be introduced or formed in the shaft, for example, by means of a drilling tool or by kneading.
- the initially still open channels are designed in the form of a circular arc in cross section. Furthermore, it can make sense that the open channels are arranged in the shaft in such a way that their longitudinal axes lie on an imaginary plane. In another variant of the invention, on the other hand, it can be provided that at least two of the initially still open channels are added to form another open channel. are ordered that their three longitudinal axes are not on an imaginary plane.
- the oil-carrying shaft is also provided with a hollow cylindrical shaft interior which is coaxial or axially parallel to the shaft longitudinal axis, a means for dividing the shaft interior being arranged in at least two channels separated from one another in the shaft interior.
- a profiled tube is arranged in this hollow cylindrical shaft interior, the circumferential surfaces of which deviate from a circular geometry form the desired channels or lines with the respectively opposite regions of the shaft inner wall.
- these shafts can have a number of advantageous configurations.
- At least one radial lubricant bore is formed in the shaft, which leads from a lubricant source to the tube arranged in the shaft interior.
- the pipe has at least at one of its ends a connection area with which it is supported on the wall of the shaft interior and / or is mounted there and seals the oil-carrying channels against one another.
- the geometry of the tube inserted into the shaft interior it can be provided that it has a cylindrical, three-legged, star-shaped or rectangular cross-sectional geometry with an at least partially circular outer circumference. About this at least partially circular outer circumference, the tube is supported pressure-tight on the wall of the shaft interior to form the channels.
- the tube inserted into the interior of the shaft can be designed as a hollow or as a solid profile.
- a tube designed as a hollow profile however, has the advantage that its interior inside the shaft interior can be used as one of the channels for the oil.
- FIG. 1 shows a longitudinal section through a gear shaft with axial oil-guiding channels formed in the central area
- FIG. 2 shows a cross section through the shaft according to FIG. 1 in the central area, but without an inserted tube
- FIG. 3 shows a cross section through the shaft as in FIG. 2, but with the tube inserted
- 4 shows a cross section through another shaft with an inserted tube
- FIG. 5 shows a longitudinal section through another transmission shaft with axial oil-guiding channels formed in the central area
- FIG. 6 shows a cross section through the shaft according to FIG. 5 in the central area with inserted rectangular tube
- FIG. 7 shows a cross section through the shaft according to FIG. 5 with inserted star-shaped or three-legged tube
- FIG. 8 shows a cross section through the shaft according to FIG. 5 with inserted star-shaped or three-legged solid profile.
- FIG. 1 shows a cross section through a transmission shaft 1, in the central area of which an axially extending cavity is formed, which is referred to below as the shaft interior 35.
- This shaft interior 35 comprises three channels 3 which are still open in the preassembly state; 4; 5, which are formed in the structure chosen for the figures 1 to 3 like three superimposed and overlapping circular bores.
- a tube 6 After a tube 6 has been inserted into this shaft interior 35, it separates the three channels 3; 4/5 so pressure-tight that they can be used, for example, as independent control pressure lines.
- the tube 6 is inserted with its one end 20 in a blind bore of the shaft 1 in a rotationally fixed manner, while the other end 19 of the tube 6 is mounted in the central bore of the shaft 1.
- FIG. 1 shows that radial pressure medium supply bores 37 or pressure medium discharge bores 38 and / or lubricant bores 7 are also formed in the shaft 1, each with one of the channels 3; 4/5 fluidically communicate.
- Fig. 2 now shows a cross section of the shaft 1 in its central region.
- the channels 3; 4; 5 still open, so that they form the elongated shaft interior 35 with a common inner wall 2.
- the channels 3; 4/5 arranged in relation to one another in the shaft 1 such that their longitudinal axes together with the shaft longitudinal axis 34 lie on an imaginary plane 36 running through the shaft 1.
- the tube 6 inserted into this shaft interior separates the channels 3; 4; 5 from each other.
- FIG. 4 now shows a cross section through another shaft 8, the shaft interior of which is formed by four overlapping circular arc-shaped channels 9 that are still open in the shaft material; 10; 11 is formed.
- the tube 13 By inserting the tube 13, the three radially outer channels 9; 10/11 separated axially and radially from the tube 13 in a pressure-tight manner, a fourth channel 12 being formed by the tube 13 if it is designed as a hollow profile as shown here.
- a multiplicity (here four) of channels 9; 10; 11; 12 can be formed, the number of which depends only on the wave diameter and the necessary cross-section of the channels.
- the shaft interior 35 of the shaft 1; 8 can advantageously be produced by overlapping bores, by kneading a pipe blank in this regard or by a suitable casting mold.
- the shaft 14 which is largely comparable to the shaft 1 is provided with a cylindrical shaft interior 39 which is aligned coaxially with the longitudinal axis 34 of the shaft 14.
- a tube 16 is inserted into this shaft interior 39, which with its two axial ends 17; 18 is rotatably and pressure-tightly connected to the inner wall 15 of the shaft 14.
- the tube 16 in this case has an essentially rectangular cross-sectional geometry in its central region, although two of the four sides of this rectangle are geometrically attached to the inner wall 15 of the shaft interior 39. have suitable surfaces. As a result, these are pressure-tight against said inner wall 15.
- the other two sides of the rectangular profile preferably have an axial cross-section reduction in the sense of two axially aligned longitudinal grooves, so that in this area between the inner wall 15 of the shaft and the outer wall of the tube, two channels 21; 22 are formed with an approximately lenticular cross-sectional geometry.
- a third channel 23 is present inside the rectangular tube 16.
- the shaft 14 has at least one radial bore 33 which is used as a pressure medium supply or pressure medium discharge bore or as a lubricant supply bore or as a lubricant discharge bore.
