Definitions
- the invention relates to a vehicle transmission with an integrated brake according to the kind defined in the preamble of claim 1.
- Vehicle transmissions with an integrated brake are used as final transmissions in vehicle axles, preferably for all types of work machines, eg. B. wheel loaders or industrial trucks, wheeled or tracked vehicles used.
- work machines eg. B. wheel loaders or industrial trucks, wheeled or tracked vehicles used.
- the disk carrier of the brake which is held in a rotationally fixed manner when the brake is actuated, is directly connected to the output of the vehicle transmission. Due to the resulting low differential speed of the brake plates, adequate cooling of the brake plates during, before and after the braking process is of particular importance.
- DE 197 18 744 C1 discloses a vehicle transmission with an integrated brake, in which the rotating inner plates are arranged in the outer region of the planet carrier and the stationary outer plates in the non-rotatable gear housing, where the lubricant experiences a centrifugal acceleration due to the rotating movement of the planet carrier and thus flows through the plates and it cools.
- EP 1 234 993 AI discloses a vehicle transmission with an integrated brake, in which the inner rotating plates are arranged on the outer circumference of the planet carrier. net and the standing disks are connected to the non-rotatably held gear housing, and lubricant reaches the disks by rotary motion of the planet carrier and is conveyed by the centrifugal acceleration in the multi-disk brake to the radially outer end of the multi-disk brake.
- the object of the present invention is to provide the brake with sufficient lubricant in a vehicle transmission with an integrated brake, which is connected in a rotationally fixed manner to the output, in order to prevent the brake from overheating.
- the transmission has a multi-disc brake, in which the discs are connected in a rotationally fixed manner to a disc carrier which is connected in a rotationally fixed manner to the output.
- the plate carrier is connected in a rotationally fixed manner to at least one cup-shaped element which, when the plate carrier rotates, absorbs lubricant and passes it on to the plates.
- the cup-shaped element is in this case connected to the plate carrier or to an element connected to the plate carrier such that the cup-shaped element is immersed in a lubricant reservoir by rotation of the plate carrier, fills up as a result and, when the plate carrier is rotated further, remains filled until the cup-shaped element remains filled horizontal center of the slat carrier and thereby the
- Lubricant is poured out of the cup-shaped element and flows to the brake discs. At higher speeds, the centrifugal force supports the outflow of the Lubricant from the cup.
- the lubricant flows from the cup-shaped element to the inner diameter of the brake plates and is distributed over the surface of the plates via grooves which are incorporated in the brake plates.
- lubricant is also supplied to the plate brake.
- a plurality of cup-shaped elements are preferably used, which are arranged evenly distributed over the circumference.
- the vehicle transmission has a planetary gear, in which the planet carrier of the planetary gear is connected in a rotationally fixed manner to the disk carrier or is formed in one piece therewith. It is possible to arrange the cup-shaped elements in or on the planet carrier or the disk carrier or to carry them out in one piece with these components.
- the planet carrier preferably has recesses in which the cup-shaped elements are arranged.
- the cup-shaped elements can be made from deep-drawn material, such as plastic or sheet steel. However, there is also the possibility of integrally forming the cup-shaped elements with the rotatable components, these being able to be produced, for example, by casting or forging.
- guide elements are arranged on rotatable parts of the vehicle transmission, which effect a targeted flow of the lubricant within the vehicle transmission, thereby replacing the
- Lubricant takes place in the immediate vicinity of the brake. This ensures that the cup-shaped elements can absorb almost cooled lubricant. If the vehicle transmission is arranged in a drive axle, then a targeted flow of the lubricant from the axle bridge to the rooms in the immediate vicinity of the brake is achieved by using the guide elements. In the area of the axle bridge in particular there is a lubricant
- the vehicle transmissions can be designed like the vehicle transmissions of DE 197 18 744 Cl and EP 1 234 993 AI, which are hereby to be included in their entirety.
- the single figure shows a section of a vehicle transmission with an integrated brake, as shown in DE 197 18 744 Cl.
- An output flange 1 is rotatably connected to the planet carrier 2, which is integrally connected to a disk carrier 3.
- the disk carrier 3 holds the inner rotating disks 4 of the disk brake 5 on its radially outer circumference.
- the outer standing disks 5 are held in the transmission housing 6 in a rotationally fixed manner.
- the output flange 1 is mounted in the gear housing 6 via a bearing 8. In the radially outer region of the planet carrier 2, this has recesses 9, in which cup-shaped elements 10 are arranged.
- the cup-shaped elements 10 which are preferably uniform are arranged on the circumference of the planet carrier 2, in a lubricant sump, not shown, whereby the cup-shaped elements are filled with lubricant.
- the lubricant passes over the lubricant sump and is thrown out of the cup-shaped elements 10 by gravity and centrifugal force above the lubricant sump.
- the lubricant thereby reaches the inner rotating plates 4 and is evenly distributed between the plates 4 and 5 by grooves in the inner rotating plates 4 or the outer standing plates 5.
- the centrifugal acceleration the lubricant eventually passes into a chamber 12 which is disposed at the radial end of the stationary outer fins 5, whereby 'the lubricant again through a channel 13 back to the
- Planet carrier 2 can flow.
- at least one guide element 14 is arranged on the planet carrier 2, which can be made in one piece with the planet carrier 2 or as a separate component, and which causes a flow in the lubricant sump when the planet carrier 2 rotates. Due to the flow in the lubricant sump, the lubricant is exchanged in the immediate vicinity of the removal point of the cup-shaped elements 10, as a result of which cooled lubricant reaches the cup-shaped elements 10.
