Definitions
- the invention relates to a container for receiving, keeping warm and/or serving food, the container having a base body that can be closed by means of a lid.
- a container for receiving, keeping warm and/or serving food the container having a base body that can be closed by means of a lid.
- connection module for connecting the cover to the base body is provided, the connection module being detachably connected both to the cover and to the base body.
- Containers for receiving, storing and dispensing food are used, for example, at buffets to keep food warm in a water bath.
- the containers typically include a trough-shaped base body which can be closed by a lid.
- the containers are known in a variety of embodiments, for example with flat or curved lids that can be opened or closed as required. which can, in order to be able to keep the food stored in the container fresh and appealing for as long as possible and, if necessary, to be able to present it.
- These containers are also known, among other things, in the catering trade under the term "chafing dish".
- a problem with these devices can be the handling of the lid.
- Removable lids which are merely placed on the base body to close them and are not connected to it in an articulated manner, require an additional parking space to be kept free.
- Lids which are hinged to the base body and which can be pivoted about horizontal axes should in turn be fully pivotable to the rear in order to be able to remove a water bath vessel, for example.
- the operator When closing the lid, the operator has to reach far back and down to grasp the lid. There is therefore a need to further develop the closing mechanism of the lid.
- cover which is hinged to the base, can be completely disassembled from the base. For example, it may be desirable to clean the lid separately from the base in a dishwasher. Although some previously known covers can be removed, they contain mechanical components which are not or only partially suitable for use in dishwashers. Other covers can only be removed from the body with a tool provided for this purpose. It would be beneficial if a workable solution for a removable lid could be found.
- the object of the invention is to design a container for receiving, keeping warm and/or serving food that is able to at least partially solve the problems described above.
- a container in particular for receiving, keeping warm and/or dispensing food.
- the container includes:
- a cover pivotable between a closed position and an open position by means of a rotary joint for closing the base body and at least one brake for braking a pivoting movement of the cover and/or for holding the cover in a position between the closed position and the open position.
- the brake has a freewheel and is designed in such a way that it brakes a pivoting movement of the cover in the closing direction, while it does not brake a pivoting movement of the cover in the opening direction.
- the freewheel typically defines a locking direction and a freewheel direction.
- the blocking direction preferably corresponds to the closing direction of the cover and/or the free-wheeling direction corresponding to the opening direction of the cover.
- the freewheel is coupled to a pivoting movement of the cover in such a way that the brake brakes or holds the cover in the closing direction, but not in the opening direction.
- the brake can be designed to hold the cover in a large number of positions, preferably steplessly, between the closed position and the open position.
- the open position refers here to the position in which the cover is opened as wide as possible and thus has a maximum opening angle.
- the maximum opening angle can be defined by at least one stop. In this case, the pivoting movement of the lid is limited by the stop.
- the cover In the closed position, the cover completely covers the base body. What is typically achieved by the brake is that the cover stops in practically any position between the closed position and the open position. The user thus only has to move the lid into a position in which the food is accessible, the lid being released automatically by the Braking force of the brake remains in this position. This also means that closing the lid requires a light hand force to overcome the braking force of the brake.
- the brake is a mechanical friction brake.
- the braking force is generated by friction between a fixed body and a moving body.
- the brake has at least one brake pad and one brake disc. Provision can be made for the brake disk to be arranged in a stationary manner in relation to the base body.
- the brake lining can move relative to the base body when the cover is moved.
- the brake lining is arranged in a stationary manner in relation to the base body. In this case, the brake disk moves relative to the base body when the cover moves.
- the pivot joint has a rotatable shaft coupled to the freewheel and connected to the cover.
- the shaft usually rotates synchronously with a pivoting movement of the cover, i.e. both elements are rotated by the same angle of rotation when the cover is pivoted.
- the brake is designed such that the brake pad and the brake disc are at rest relative to one another in the free-wheeling direction of the shaft and a relative movement of the brake pad and the brake disc is braked in the blocking direction of the shaft.
- a spring element can be provided, the spring element being designed to compress the brake lining and the brake disc in the axial direction.
- the shaft can be surrounded by a bearing bush.
- the shaft can be arranged or mounted in an interior space defined by the bearing bush.
- the bearing bush can be connected to at least one cover which at least defines the interior space defined by the bearing bush partially closed.
- the brake lining can, for example, be connected to the bearing bush in a non-rotatable manner, for example by a form fit.
- the freewheel can be mounted on the shaft.
- the freewheel is often designed as a sleeve freewheel.
- the freewheel is arranged radially between the bearing bush and the shaft.
- at least one roller bearing is arranged radially between the bearing bush and the shaft, for example two roller bearings or even more than two if required.
- at least one roller bearing is integrated in the freewheel.
- At least one sealing element can be provided, which is designed to seal the freewheel and/or the at least one roller bearing against water and moisture.
- the brake can also be arranged in a housing, which housing can sometimes have two sub-housings.
- the brake can be arranged in or on a connection module which connects the cover to the base body.
- the connection module described below is particularly suitable for the connection module.
- the brake disk can surround the shaft, the freewheel and/or the bearing bush in the radial direction.
- a sliding bearing is arranged radially between the bearing bush and the brake disk, which allows rotation, preferably low-friction rotation, of the bearing bush relative to the brake disk.
- the brake of the type described above a low-noise braking function can be achieved with a long service life. Furthermore, the described brake enables stepless cover positioning.
- the brake is further characterized by a small number of components and simple assembly.
- another container is proposed, in particular for receiving, keeping food warm and/or serving it.
- the container includes
- connection module for connecting the cover to the base body.
- connection module has a first connection element which is detachably connected to the cover.
- the connection module also has a second connection element which is detachably connected to the base body.
- the connection module also has at least one component for influencing a pivoting movement of the cover.
- connection module thus enables modular coupling of the cover to the base body.
- the connection module can be removed from both the base body and the cover . Due to the modularity of the coupling, the base body, the cover and the connection module can be individually replaced, repaired and/or cleaned. For example, the base body and the cover can be cleaned separately from the connection module. This can be particularly useful if the connection module or whose components, such as the components mentioned for influencing the pivoting movement of the lid, are sensitive to water, moisture and/or cleaning agents.
- Said component can have or be a brake for braking a pivoting movement of the lid and/or for holding the lid in a position between the closed position and the open position.
- the brake can be designed like the brake mentioned in relation to the first aspect.
- said component can include or be a motor element for moving the cover between the closed position and the open position.
- the connection module can include a housing in which the component is arranged.
- the first connecting element has a first form-fitting element, which can be connected to a first counterpart attached to the cover in order to form a first form-fitting connection.
- the first form- Final element configured as a projection
- the first counterpart has a complementarily shaped first receptacle.
- a first spring-loaded pressure piece which snaps into a first locking recess when the first positive connection is present.
- the first resilient pressure piece can contribute to fixing the first form fit.
- the first resilient pressure piece is installed in the first form-fitting element, for example.
- the first locking recess may be formed in the first counterpart.
- the first locking recess is usually formed in an inner wall of the counterpart.
- the first resilient pressure piece can also be installed in the counterpart. In this case, the first locking recess is formed in the first form-fitting element.
- the first connection can preferably be released from an opening angle of the cover of at least 45° without the base body having to be held in place by hand.
- a spring force or holding force of the first spring-loaded pressure piece and/or the geometry of the first form-fitting connection can be designed in such a way that the manual force required to release the first connection is generally available at an opening angle of the cover between 80° and 100°, preferably between 85° and 85° ° and 95°, in particular about 90°, is smallest.
- a longitudinal axis (or longitudinal direction) of the first form-fitting element and a longitudinal axis (or longitudinal direction) of the first counterpart extend parallel to gravity at a certain opening angle, in particular 90°, of the lid, so that the positive connection of the lid with the first connecting element in the Open position can be solved by lifting the lid.
- the second connecting element comprises a second form-fitting element, which can be connected to a second counterpart fastened to the base body in order to form a second form-fitting connection.
- a second resilient pressure piece is often provided, which snaps into a second locking recess when the second positive connection is present.
- the second resilient pressure piece can contribute to fixing the second form fit.
- the second resilient pressure piece is installed in the second form-fitting element, for example.
- the second locking recess may be formed in the second counterpart.
- the second locking recess is usually formed in an inner wall of the second counterpart.
- the second resilient pressure piece can also be installed in the second counterpart. In this case, the second locking recess is formed in the second form-fitting element.
- the second positive-locking element engages in a second receptacle formed in the counterpart.
- the second positive-locking element is designed as a bolt, while the second receptacle has a complementary shape.
- the second locking recess is usually formed in an inner wall of the second receptacle.
- the second resilient pressure piece can be installed in the second positive-locking element.
- a longitudinal axis of the second resilient pressure piece can in particular extend at an angle, preferably perpendicularly, to a longitudinal axis of the second positive-locking element.
- the second locking recess can be designed as a through opening, so that the second resilient pressure piece can be released from the outside, preferably by finger pressure.
- a third resilient pressure piece can be provided, which is prestressed when the second resilient pressure piece is in the engaged state.
- the third resilient pressure piece can be designed to at least partially press the second positive-locking element out of the receptacle when the second pressure piece is released from the second locking recess.
- a longitudinal axis of the third resilient pressure piece can be aligned parallel to the longitudinal axis of the second form-fitting element and/or perpendicular to the longitudinal axis of the second resilient pressure piece.
- the third resilient pressure piece is installed in the second form-fitting element.
- the third resilient pressure piece can bear against the inner wall of the receptacle when the second resilient pressure piece is in the engaged state.
- a third depression can be formed in the inner wall of the receptacle, in which the third pressure piece engages.
- At least one of the above-mentioned resilient pressure pieces can have a sleeve and a spring element arranged in the sleeve as well as a pressure piece, such as a ball or a pin, arranged partially in the sleeve and partially protruding from the sleeve.
- the spring element is designed to exert a spring force on the pressure piece, as a result of which the pressure piece is prestressed.
- first connecting element and the second connecting element are connected to one another via a center piece, with the component for influencing a pivoting movement of the cover optionally being attached to the center piece or being installed in the center piece.
- the container may sometimes have two connection modules of the type described. It can be provided that the longitudinal directions of the first form-fitting elements extend parallel to one another and point in the same direction. The first positive locking can thus be released at the same time by pulling on the cover. It can also be provided that the longitudinal directions of the second form-fitting elements run parallel to one another, but are directed in opposite directions (antiparallel). The consequence of this is that the second form closures cannot be released as long as the cover is still attached to the connection modules. Instead, the second positive locking (that is, the connection of the connection modules to the base body) can only be released when the cover has been removed from the connection module. This can reduce the likelihood that the lid will be cleaned along with the connector modules.
- the base body is often designed in the form of a trough.
- the base body comprises a bottom surface, a front wall, a rear wall and two side walls, with the connection module preferably being fastened to the rear wall of the base body, in particular to an upper side of the rear wall.
- the rear wall may extend laterally from a first end portion to a second end portion, each end portion being connected to a side wall.
- the connection modules are preferably fixed in the end sections of the rear wall. The reason for this external connection of the connection modules is the usage the flexural rigidity of the side walls and/or the corner radii. Thereby, back panel flexing during opening or closing of the lid can be prevented or reduced.
- the bottom surface, the front wall, the rear wall, the side walls and/or the base body can thus be designed in one piece. In addition to reduced production costs, this can ensure an attractive appearance and/or reduced cleaning effort. At least one bearing block is sometimes provided on the base body for connection to the second connection element.
- connection of the connection module to the base body can be designed in such a way that the connection module can be easily removed and thus replaced without tools.
- the possibility can also be created of replacing or upgrading the component for influencing a pivoting movement of the cover with another component at a later point in time, without having to redesign the base body and/or the cover to have to.
- connection module can also be provided (e.g. with a motor element/without a motor element and/or with a brake/without a brake), which are interchangeable.
- the invention can also provide a system which has the base body, the cover and at least two connection modules, the connection modules preferably each having a different component for influencing the pivoting movement of the cover.
- the container according to the first aspect can be combined with features of the container according to the second aspect and vice versa.
- the container according to the first aspect and the container according to the second aspect have the same features.
- the container according to one of the aspects described above can be part of a system with additional components be.
- a water bath vessel can also be provided, which is accommodated by the base body.
- An intermediate space formed between the base body and the water bath vessel can be filled with water.
- a heater may be provided to heat and/or keep the water warm.
- the container can be arranged, for example, on a frame with a heating device underneath, for example fuel cans or electric heating elements being able to be used as the heating device.

If the cover 10 is lifted in this position, the pressure piece 23 is released from the locking recess 14 so that the first form fit can be released and the cover 10 can be removed from the connection module 20.
- the first positive-locking element 22 is received by the first receptacle 13 of the counterpart 12 .
- the first form-fit element receives the counterpart (not shown).

- the second counterpart is realized by a bearing block 9, with the second positive-locking element 32 being designed as a bolt.
- a longitudinal axis 42 of the bolt, ie of the second positive-locking element 32 generally runs parallel to the pivot axis 40 of the cover 10, preferably perpendicular to the longitudinal axis 41 and often perpendicular to the force of gravity.
- the bearing block 9 usually has a second receptacle 15 which receives the bolt 32 in a form-fitting manner.
- a second locking recess 16 can be formed in the inner wall of the second receptacle 15 .
- a second spring-loaded pressure piece 33 can be installed in the bolt 32 , which snaps into the second locking recess 16 when the second positive connection is present.
- a longitudinal axis of the second resilient pressure piece 33 usually extends at an angle to the longitudinal axis 42 of the bolt 32, a preferred angle being between 80° and 100° and in particular approximately 90°.
- the second locking recess 16 can be designed as a through opening in the bearing block 9 through which the second resilient pressure piece 33 protrudes. As a result, a user has access to the second spring-loaded pressure piece 33 from the outside and can actuate it with the touch of a finger. connecting The second positive locking can then be released.
- a third spring-loaded pressure piece 34 can be provided, which on the one hand fixes/centers the second form fit when the second pressure piece 33 engages in the second locking recess 16 and on the other hand supports the release of the second form fit when the second pressure piece 33 is pressed out of the second locking recess 16 can be designed.

- the third resilient pressure piece 34 is prestressed in the engaged state of the second resilient pressure piece 33 and is in contact with an inner wall of the second receptacle 15 .
- the third resilient pressure piece 34 can engage in a third locking recess 35 which is formed in the receptacle 15 .
- a longitudinal axis of the third resilient pressure piece 34 extends parallel to the longitudinal axis 42 of the bolt 32 and thus perpendicular to the longitudinal axis of the second resilient pressure piece 33.
- connection module 20 moves out of the bearing block 9 by the spring force of the third spring-loaded pressure piece 34, in order to give the operator a haptic and/or to give acoustic feedback that the connection module 20 or the brake 50 is released and ready for removal.
- the second pressure piece 33 and/or the third pressure piece 34 can be constructed in a similar way to the first pressure piece 23.
- the respective pressure piece 33, 34 can have a sleeve, a compression spring and an element prestressed by the compression spring, which can be configured as a ball, for example or pin can be formed.
- the prestressed element usually protrudes partially from the sleeve and is retained in the sleeve by means of a radially inwardly projecting projection formed by the sleeve.
- the second form-fitting element 32 is thus received in a form-fitting manner by the second receptacle 15 of the bearing block 9 .
- the second form-fitting element receives the counterpart (not shown).
- the second positive-locking element has a second receptacle, which preferably has a second locking recess.
- the counterpart is also designed as a projection which can be received in a form-fitting manner by the second receptacle.

- connection modules 20 are provided, which are arranged mirror-symmetrically to each other.
- a plane of mirror symmetry typically runs parallel to the side walls 6, 7.
- the longitudinal axes 42 of the second positive-locking elements 32 designed as bolts preferably point away from one another and are therefore aligned antiparallel to one another. In order to release the respective second positive locking, the bolts 32 must therefore be pulled out of the second receptacles 15 in opposite directions.
- the longitudinal axes 41 of the first form-fitting elements 22 are preferably aligned parallel to one another and point in the same direction. Thus, by pulling on the cover or lifting the cover 10, preferably at an opening angle of about 90°, the first form closures can be released at the same time.
- the alignment of the longitudinal axes 41, 42 also means that the second form fit can only be released after the cover 10 has been removed from the respective connection module 20.

- Each bearing block 9 is preferably at one upper side of the flat portion of the rear wall 5 arranged.
- the bearing block 9 preferably borders on the transition area 8 and is thus positioned on the outside (outer right or outer left) on the rear wall 5 .
- the reason for connecting the connection module 20 to the outside is to use the flexural rigidity of the side walls 6, 7 and the transition areas 8. This can prevent the rear wall from bending during opening and closing, and additional rear wall reinforcements can be dispensed with.
- the brake 50 is discussed in more detail below.
- the brake 50 designed as a friction brake is provided to brake the pivoting movement of the cover 10 and to hold the cover 10 in a position between the closed position and the open position.

- the freewheel 52 can be designed, for example, as a sleeve freewheel.
- the lid 10 is coupled to a rotatable shaft 54 which defines an axis of rotation or pivot axis 40 .
- the shaft 54 can have a non-circular projection 56 which extends in the axial direction and which engages in a form-fitting manner in a corresponding recess 57 in the first housing part 18 .

- a bearing bushing 58 enclosing the shaft 54 can optionally be provided.
- the bearing bush 58 can define an interior of the brake 50 in which the freewheel 52 is located.
- the freewheel 52 is preferably arranged radially between the bearing bush 58 and the shaft 54 .
- the freewheel 52 is arranged directly on the shaft 54, so there are no other components between the freewheel 52 and the shaft 54.
- Two roller bearings 60 are also provided, which are arranged on both sides of the freewheel 52 on the shaft 54.
- the roller bearings 60 can be deep groove ball bearings, for example, and are generally arranged radially between the bearing bush 58 and the shaft 54 .
- the roller bearings 60 allow the shaft 54 to rotate relative to the bearing bush 58.
- the bearing bush 58 can have a circumferential, radially inward-pointing projection 61, which often adjoins the roller bearing 60 on the one hand and the freewheel 52 on the other hand in the axial direction.
- Two retaining rings 66 can be provided, each adjoining the ball bearing 60 and forming an axial boundary for the ball bearing 60 .
- the bushing 58 can also have a shoulder 59 which points radially outwards.

- the shaft 54 may have a plurality of steps extending in the radial direction and juxtaposed in the axial direction.
- the elements 53, 50 and 66 can each be arranged on a step of different radial height.
- a first cover 62 can be provided to cover the interior space of the brake 50 enclosed by the bearing bush 58 .
- the bearing bush 58 can be non-rotatably connected to the first cover 62, e.g. by means of screws 63 which engage in the shoulder 59, for example.
- a sealing element 64 such as an O-ring, which can be formed from an elastic material, can be provided radially between the bearing bush 58 and the first cover 62 for sealing purposes.
- a further sealing element such as a radial shaft sealing ring 65 can be provided radially between the cover 62 and the shaft 54 .
- the radial shaft sealing ring 65 defines an area 53 which is filled with a lubricant such as grease for lubrication and further sealing (cf. FIG. 16).
- the O-ring 64 and the radial shaft sealing ring 65 seal the interior of the brake 50, in which the sleeve freewheel 52 and the ball bearings 60 are located. adequately protected against water and moisture.
- the bearing bush 58 can be connected to a second cover 68 .
- the first cover 62 and the second cover 68 can thus be arranged on axially opposite sides of the bearing bush 58 .
- the second cover 68 preferably has an internal thread which can be screwed to an external thread of the bearing bush 58 .
- a spacer ring 67 or spacer sleeve can be arranged axially between the second cover 68 and the bearing bush.
- a locking ring O-ring 69 can be provided axially between the second cover 68 and the second housing part 19 . The O-ring is used to seal against external fluids that might otherwise enter element 68 through the small threads.
- a sealing paste for example, can preferably be arranged at least in regions between the elements 68, 67 and 58 in order to seal this region against moisture from the outside.
- the first cover 62 and the second cover 68 together with the bearing bush 58 can be regarded as the inner housing, while the first housing part 18 and the second housing part 19 can be regarded as the outer housing.
- FIG. 11 shows an exploded view of the brake 50 or the connection module 20.
- the bearing bush 58 typically comprises a round section and a flat section radially on the outside in the direction of rotation.
- the flat section of the bearing bush 58 is particularly suitable for a non-rotatable form fit with components arranged on the bearing bush 58 .
- the brake 50 can also have at least one brake pad 70 , preferably two brake pads 70 , and a brake disc 72 .
- the term "brake disc” used in this document was chosen in analogy to a disc brake of a vehicle and because of the disc-like shape of the element 72. Unlike a disc brake used in a vehicle, however, the brake pads 70 rotate while the brake disc 72 rests.
- the term “brake disc” can also be phrased as "brake lever” or "brake arm”.
- the brake pads 70 are usually arranged on the bearing bush 58 and can have a flat section on their inner side in order to enable a non-rotatable form fit with the bearing bush 58 .
- the brake disc 72 is generally firmly connected to the rigid center piece 29 and is therefore arranged in a stationary manner in relation to the base body 2 .
- the brake pads 70 are arranged on both sides of the brake disk 72 in the axial direction.
- a spring element 74 is preferably provided, which presses the brake pads 70 and the brake disk 72 together in the axial direction.
- the spring element 74 can be designed as a wave spring, for example.
- a shim washer 73 can be arranged between the brake lining 70 and the spring element 74 , which washer distributes a spring force of the spring element 74 evenly over the brake lining 70 .
- a further disk 75 can be arranged with a form fit, which rests against an end face of the second cover 68 .
- the purpose of this washer 75 is that the wave spring 74 is not twisted when the second cover 68 is screwed on.
- a sliding bearing 76 can be arranged radially between the brake disk 72 and the bearing bush 28 , which enables the bearing bush 58 to rotate relative to the brake disk 72 .
- the greatest possible opening angle of the lid 10 can be determined by a stop 48 located on the center piece 29, the stop 48 sometimes being referred to as a nose.
- the pivoting movement of the cover 10 is thus limited by this stop 48 .
- the stop 48 engages in a slot-shaped recess 49 which runs, for example, axially between the brake disc 72 and the first housing part 18 and extends in the circumferential direction.
- FIG. Fig. 16 shows a section of a brake 50 and a connection module 20 which are fixed to the left of the container 1, while the brake 50 and the connection module 20 of Fig. 10 are fixed to the right of the container 1.
- the brake 50 of FIG. 16 is designed to be somewhat shorter axially than the brake 50 of FIG. 10.
- two power flows are indicated by means of arrows 46, 47.
- the arrows 47 indicate the flow of force when the cover 10 is opened, while the arrows 46 indicate the flow of force when the cover 10 is closed.
- the cover 10 is connected to the first housing part 18 and to the shaft 54 in a rotationally fixed manner via the first positive-locking element 22 .
- the opening direction of the cover 10 corresponds to the freewheeling direction 45 of the shaft 54 and the freewheel 52, so that the shaft 54 rotates when the cover 10 is opened.
- the torque is therefore not passed on to the braking mechanism and the brake 50 is therefore not actuated in this case.
- the components 19, 58, 68, 70 in particular do not rotate.
- the at least one brake pad 70 and the brake disk 72 are at rest relative to one another in the freewheeling direction 45 of the shaft 54 .
- the rotation of the shaft 54 is transmitted from the freewheel 52 to the bearing bush 58 by frictional locking.
- the torque is transmitted from the bearing bush 58 to the brake pads 70 by means of a form fit.
- the brake pads 70 are pressed against the axial end faces of the brake disc 72 by the spring element 74 .
- a relative movement of the brake lining 70 and the brake disk 72 is braked in the blocking direction 44 of the shaft 54 , and the braking effect is thus generated by the friction between the brake linings 70 and the brake disk 72 . Overall, therefore, the rotation of the shaft 54 and the pivoting movement of the cover 10 are braked.
- the force exerted on the brake disc 72 flows off via the center piece 29 and the second connecting element 21 onto the bearing block 9 and the container 1 . If no manual force is applied and only gravity acts on the lid 10, the brake 50 ensures that the lid 10 is held in position.
- the braking force is preferably designed in such a way that the cover 10 is held continuously and without play in any position between the closed position and the open position. This also means that closing the lid 10 requires a slight hand force to overcome the holding force of the brake 50 . This required manual force is greatest in a completely open position at about 90° and decreases due to the increasing influence of gravity when closing. Shen of the lid 10 from steadily.
- the plain bearing 76 arranged between the brake disk 72 and the bearing bush 58 allows a relative rotational movement of the bearing bush 58 relative to the brake disk 72.
- the components 19, 58, 68, 70 and the components connected thereto in a rotationally fixed manner also rotate .
- FIG. 17 shows a longitudinal section of a similar brake 50, which has a simpler construction than the brake 50 shown in the sectional view of FIG. 10.
- the same features are provided with the same reference numbers, and a repetition of the description is made omitted here.
- the brake 50 has a sleeve-type freewheel 51 in which two roller bearings are integrated. Thus, the separate roller bearings 60 of FIG. 10 can be dispensed with.
- the first cover 62 is omitted in the embodiment of FIG. 17.
- An optional radial shoulder 30 of the shaft 54 delimits the freewheel 51 in the axial direction, so that a retaining ring 66 can also be dispensed with in this area.
- a shim 77 is arranged axially between the locking ring 66 and the freewheel 51 .
- the brake 50 of Fig. 17 thus requires fewer components than the brake 50 of Fig. 10, see also the exploded view of the brake 50 in Fig. 18.
- FIG. 19 discloses a longitudinal section of the brake 50.
- the brake of FIG. 19 is similar to the brake 50 of FIG. 17 in that the roller bearings in which the freewheel 51 are integrated and the first cover 62 of the brake 50 of FIG. 10 was dispensed with.
- an optional sealing ring 78 is provided in the brake of FIG. 19, which radially seals the system to the outside.
- the sealing ring 78 is typically located between the brake disk 72 and the first partial housing 18.
- the sealing ring 78 is preferably embedded in a groove 79 of the brake disk 72.
- Another sealing ring 78 between the Brake disk 72 and the second partial housing 19 can be arranged, preferably also in a groove 79 of the brake disk 72.
- quad rings can optionally be selected for the seals 78, which usually have a lubricant reservoir, which minimizes friction.
- a sealing paste and/or an additional sealing element can also be provided for sealing in order to shield the system from moisture from the outside.
- FIG. 19 Another special feature of the embodiment of FIG. 19 is that the second cover 68 has been dispensed with. Instead, the second housing part 19 is connected directly to the bearing bush 58, typically via a screw connection. As a result, fewer parts are required.
