Definitions
- This invention relates to a technology for preventing unauthorized removal of car wheels. More specifically, a universal comprehensive locking system for car wheels is disclosed.
- U.S. Pat. Nos. 8,739,585 and 8,943,865 disclose antitheft devices for car wheels. These devices can be removed relatively easily by an experienced thief and thus do not provide a truly reliable wheel lock.
- U.S. Pat. No. 9,689,180 issued to the inventor of this application provides a device that provides secure wheel lock. However, the device has a multitude of parts and needs to be modified to fit to various car wheels. Considering the great variety of car makes and models all over the world, there is a need for an improved wheel lock system that fits, without substantial adjustments, to most car wheels.
- a device for locking a wheel of a vehicle comprises a main module, a center bolt, an expander and a locking mechanism.
- the main module comprises a plurality of elements configured to cover the nuts or bolts by which the wheel is attached to the vehicle.
- the center bolt is adapted to be connected to the main module by means of a threading such that the axial position of the center bolt (as seen along the axis of rotation of the wheel) can be adjusted by rotating the center bolt relative the main module.
- This axial movement of the center bolt causes the expander, which is adapted to be operably connected to the center bolt, to expand in a radial direction of the wheel to engage with the wheel and thereby secure the device to the wheel.
- the locking mechanism is adapted to be arranged in a locking state in which the locking mechanism prevents the center bolt from rotating relative the main module, and in an open state in which the locking mechanism allows the center bolt to rotate relative the main module.
- the plurality of elements adapted to cover the nuts or bolts of the wheel may be understood as protective cases or blocking means adapted to restrict, limit or block access to the bolt heads and/or lug nuts, thereby hindering or at least making it harder for an unauthorized person to undo the bolts/lug nuts and remove the wheel.
- the protective elements may form an integral part of the main module, or be attached as separate items to the same, and may preferably be arranged in a pattern corresponding to the position of the bolts/nuts of the wheel.
- the center bolt may be threaded directly in the material of the main module, or indirectly via a socket or spacer that is fixated in the main module.
- the socket may be formed of a material having a higher stability and mechanical strength than the material of the remaining parts of the main module.
- the threading may be oriented such that the center bolt, upon rotation in the threading, moves along the axis of rotation of the wheel. The rotation may for example be achieved by means of a key or a wrench fitting with the center bolt.
- the expander is arranged to secure the device to the wheel. This may for example be achieved by a mechanical means that is operated by the axial movement of the center bolt to engage with the wheel.
- the mechanical means may for example be configured to expand in the radial direction of the wheel upon rotation of the center bolt, resulting in an interference fit or press fit between the expander and the wheel.
- the device may be securely fixed to the wheel by tightening the center bolt.
- the locking mechanism When the device has been installed and secured to the wheel, for example by tightening the center bolt as described above, the locking mechanism may be brought into its locking state to prevent an unauthorized entity from removing the locking device and thereby accessing the nuts/bolts of the wheel.
- the locking mechanism may be configured to prevent the center bolt from being turned or rotated in the main module. This may be achieved in a number of ways, some of which being discussed in further detail in connection with the detailed description of the drawings.
- the locking mechanism may comprise a bolt that can be fixed to the center bolt and to the main module to prevent rotational movement between the two.
- the bolt of the locking mechanism may for example have a flat side that engages with a corresponding surface in the center bolt and the main module to keep the bolt from rotating.
- the locking mechanism may, in the locking state, be axially secured to the wheel by means of a washer configured to engage with a backside of the main module. To bring the locking mechanism in the open state, the washer may be rotated such that it can be released from its engagement with the main module and the bolt removed from the center bolt.
- the locking mechanism may comprise a locking pin or ball that can be moved in the radial direction and engage with the center bolt to prevent it from rotating and to the secure the locking mechanism to the device in the axial direction. To release the locking mechanism, the locking pin or the locking ball can be retracted.
- the locking mechanism may in some examples be a key operated lock, such as e.g. the Assa Desmo+ camlock.
- the expander may comprise a plurality of segments, wherein each of the segments is movable in the radial direction so as to engage the device to the wheel.
- each segment may comprise a tapered surface configured to slide on a corresponding tapered or cone shaped surface of the center bolt as the center bolt moves in the axial direction.
- the tapered surfaces of the center bolt and the segment may cooperate to transform an axial movement of the center bolt into a radial movement of the segment.
- the expander is allowed to be radially press fitted to the rim or wheel when upon tightening of the center bolt.
- the segments may in some examples form part of a circular washer arranged around the center bolt.
- the expander comprises a material configured to be compressed elastically in the axial direction and to expand elastically in the radial direction as the axial position of the center bolt is adjusted.
- the expander may, according to this embodiment, for example be a washer or plate arranged to be compressed between an end portion of the center bolt and the backside of the main module (i.e., the side of the module facing the wheel when mounted) as the center bolt is rotated. By compressing the expander in this manner, it may at the same time be caused to expand laterally or radially and thereby be press fitted to the rim or wheel.
- elastic material may include a polymeric material such as e.g. rubber.
- the expander may comprise a retaining means configured to pull the segments towards a center of the expander.
- the retaining means may for example be formed as a rubber band encircling the periphery of the annular segments for pushing them together and prevent them from falling apart when the device is removed from the wheel.
- the periphery of the segments may be provided with a groove for accommodating the retaining means. The groove may be arranged in the contact surface that engages the wheel, so as to protect the retaining means from being damaged by the press fitting.
- the expander may cooperate with the axial movement of the center bolt so as to fasten the device to the wheel by means of a force acting in the axial direction, the radial direction or a combination of both.
- the radial engagement may be achieved by a radial expansion of the expander as described above, whereas the axial engagement may be achieved by allowing the expander to engage a shoulder of the wheel. In the latter case, the expander may be inserted behind the shoulder and expanded radially such that is prevented from being retracted.
- the locking mechanism may comprise an axial recess, or lock-hole, formed in the center bolt, a detachable socket having a through hole and being adapted to be rotationally secured to the main module, and a detachable locking bolt, or lock, adapted to be inserted into the main module via the through hole and the axial recess.
- the axial recess and the through hole may be configured to be aligned with each other, and the locking bolt may be adapted to prevent the center bolt from rotating relative the socket.
- the detachable socket may comprise recesses and protrusions, also referred to as teeth and flat areas, configured to engage with corresponding recesses and protrusions, also referred to as a ‘specific pattern’, of the main module.
- the device may further comprise a locking socket adapted to be rotationally secured to the main module, wherein the locking socket comprises an inner threading adapted to receive a locking bolt, and recesses and protrusions forming a pattern configured to engage with a corresponding pattern of recesses and protrusions of the detachable socket.
- the locking socket may be used together with the locking bolt to prevent the center bolt from rotating.
- the locking bolt may be configured to be inserted via a front side of the device (facing away from the wheel) and to be secured in the axial direction by engaging a back side of the device (facing the wheel).

Abstract
Description
- This invention relates to a technology for preventing unauthorized removal of car wheels. More specifically, a universal comprehensive locking system for car wheels is disclosed.
- Unauthorized removal of car parts, specifically alloy wheels, is a frequently occurring problem all over the world. Due to their high value, custom wheels and tire rims are examples of items frequently stolen. Accordingly, there is a great need for devices and techniques for protecting wheels from unauthorized removal.
- There have been attempts to provide such protection. For example, U.S. Pat. Nos. 8,739,585 and 8,943,865 disclose antitheft devices for car wheels. These devices can be removed relatively easily by an experienced thief and thus do not provide a truly reliable wheel lock. U.S. Pat. No. 9,689,180 issued to the inventor of this application provides a device that provides secure wheel lock. However, the device has a multitude of parts and needs to be modified to fit to various car wheels. Considering the great variety of car makes and models all over the world, there is a need for an improved wheel lock system that fits, without substantial adjustments, to most car wheels.
- It is an object of this invention to provide a universal locking system fitting to majority of car wheels to prevent unauthorized removal of the wheels.
- Hence, according to a first aspect, a device for locking a wheel of a vehicle is provided. The device comprises a main module, a center bolt, an expander and a locking mechanism. The main module comprises a plurality of elements configured to cover the nuts or bolts by which the wheel is attached to the vehicle. The center bolt is adapted to be connected to the main module by means of a threading such that the axial position of the center bolt (as seen along the axis of rotation of the wheel) can be adjusted by rotating the center bolt relative the main module. This axial movement of the center bolt causes the expander, which is adapted to be operably connected to the center bolt, to expand in a radial direction of the wheel to engage with the wheel and thereby secure the device to the wheel. Finally, the locking mechanism is adapted to be arranged in a locking state in which the locking mechanism prevents the center bolt from rotating relative the main module, and in an open state in which the locking mechanism allows the center bolt to rotate relative the main module.
- The plurality of elements adapted to cover the nuts or bolts of the wheel may be understood as protective cases or blocking means adapted to restrict, limit or block access to the bolt heads and/or lug nuts, thereby hindering or at least making it harder for an unauthorized person to undo the bolts/lug nuts and remove the wheel. The protective elements may form an integral part of the main module, or be attached as separate items to the same, and may preferably be arranged in a pattern corresponding to the position of the bolts/nuts of the wheel.
- The center bolt may be threaded directly in the material of the main module, or indirectly via a socket or spacer that is fixated in the main module. In case a socket is used, the socket may be formed of a material having a higher stability and mechanical strength than the material of the remaining parts of the main module. The threading may be oriented such that the center bolt, upon rotation in the threading, moves along the axis of rotation of the wheel. The rotation may for example be achieved by means of a key or a wrench fitting with the center bolt.
- The expander is arranged to secure the device to the wheel. This may for example be achieved by a mechanical means that is operated by the axial movement of the center bolt to engage with the wheel. The mechanical means may for example be configured to expand in the radial direction of the wheel upon rotation of the center bolt, resulting in an interference fit or press fit between the expander and the wheel. Thus, the device may be securely fixed to the wheel by tightening the center bolt.
- When the device has been installed and secured to the wheel, for example by tightening the center bolt as described above, the locking mechanism may be brought into its locking state to prevent an unauthorized entity from removing the locking device and thereby accessing the nuts/bolts of the wheel. The locking mechanism may be configured to prevent the center bolt from being turned or rotated in the main module. This may be achieved in a number of ways, some of which being discussed in further detail in connection with the detailed description of the drawings. In one example, the locking mechanism may comprise a bolt that can be fixed to the center bolt and to the main module to prevent rotational movement between the two. The bolt of the locking mechanism may for example have a flat side that engages with a corresponding surface in the center bolt and the main module to keep the bolt from rotating. The locking mechanism may, in the locking state, be axially secured to the wheel by means of a washer configured to engage with a backside of the main module. To bring the locking mechanism in the open state, the washer may be rotated such that it can be released from its engagement with the main module and the bolt removed from the center bolt. Alternatively, or additionally the locking mechanism may comprise a locking pin or ball that can be moved in the radial direction and engage with the center bolt to prevent it from rotating and to the secure the locking mechanism to the device in the axial direction. To release the locking mechanism, the locking pin or the locking ball can be retracted.
- The locking mechanism may in some examples be a key operated lock, such as e.g. the Assa Desmo+ camlock.
- According to an embodiment, the expander may comprise a plurality of segments, wherein each of the segments is movable in the radial direction so as to engage the device to the wheel. In one example, each segment may comprise a tapered surface configured to slide on a corresponding tapered or cone shaped surface of the center bolt as the center bolt moves in the axial direction. Thus, the tapered surfaces of the center bolt and the segment may cooperate to transform an axial movement of the center bolt into a radial movement of the segment. In this way, the expander is allowed to be radially press fitted to the rim or wheel when upon tightening of the center bolt. The segments may in some examples form part of a circular washer arranged around the center bolt.
- According to an embodiment, the expander comprises a material configured to be compressed elastically in the axial direction and to expand elastically in the radial direction as the axial position of the center bolt is adjusted. The expander may, according to this embodiment, for example be a washer or plate arranged to be compressed between an end portion of the center bolt and the backside of the main module (i.e., the side of the module facing the wheel when mounted) as the center bolt is rotated. By compressing the expander in this manner, it may at the same time be caused to expand laterally or radially and thereby be press fitted to the rim or wheel. Examples of elastic material may include a polymeric material such as e.g. rubber.
- According to an embodiment, the expander may comprise a retaining means configured to pull the segments towards a center of the expander. The retaining means may for example be formed as a rubber band encircling the periphery of the annular segments for pushing them together and prevent them from falling apart when the device is removed from the wheel. The periphery of the segments may be provided with a groove for accommodating the retaining means. The groove may be arranged in the contact surface that engages the wheel, so as to protect the retaining means from being damaged by the press fitting.
- It will be appreciated that the expander may cooperate with the axial movement of the center bolt so as to fasten the device to the wheel by means of a force acting in the axial direction, the radial direction or a combination of both. The radial engagement may be achieved by a radial expansion of the expander as described above, whereas the axial engagement may be achieved by allowing the expander to engage a shoulder of the wheel. In the latter case, the expander may be inserted behind the shoulder and expanded radially such that is prevented from being retracted.
- According to an embodiment, the locking mechanism may comprise an axial recess, or lock-hole, formed in the center bolt, a detachable socket having a through hole and being adapted to be rotationally secured to the main module, and a detachable locking bolt, or lock, adapted to be inserted into the main module via the through hole and the axial recess. The axial recess and the through hole may be configured to be aligned with each other, and the locking bolt may be adapted to prevent the center bolt from rotating relative the socket.
- According to an embodiment, the detachable socket may comprise recesses and protrusions, also referred to as teeth and flat areas, configured to engage with corresponding recesses and protrusions, also referred to as a ‘specific pattern’, of the main module. This allows for the socket to be both detachable (i.e., dismounted in the axial direction) and rotationally secured to the main module.
- According to an embodiment, the device may further comprise a locking socket adapted to be rotationally secured to the main module, wherein the locking socket comprises an inner threading adapted to receive a locking bolt, and recesses and protrusions forming a pattern configured to engage with a corresponding pattern of recesses and protrusions of the detachable socket. The locking socket may be used together with the locking bolt to prevent the center bolt from rotating.
- According to an embodiment, the locking bolt may be configured to be inserted via a front side of the device (facing away from the wheel) and to be secured in the axial direction by engaging a back side of the device (facing the wheel).
- The above, as well as additional objects, features and advantages of the present invention, will be better understood through the following illustrative and non-limiting detailed description, with reference to the appended drawings. In the drawings, like reference numerals will be used for like elements unless stated otherwise.

Themain module 1 has acenter part 16 comprising an edge orcorner 13 adjusted to fit different rims with center hole diameter of different sizes. Thecorner 13 may rest directly on the rim or there may be spacers between the rim and the corner. Thecorner 13 may also have an extension (not shown in the present figure) to fit different rims. Themain module 1 also has aspace 10 which is adjusted to each different hub caps and aridge 11 to secure the hub caps on place. -
FIGS. 2A-C shows the locking cap, or locking socket.FIG. 2A is a cross sectional view andFIG. 2B is a top view.FIG. 2C is a perspective view. The lockingcap 2 has acylindrical part 23 and acircular part 21 that has ahole 22 having same size and shape as an inner part of a lock (shown inFIG. 6 ). The outer rim of thecircular part 21 has a toothed pattern comprising of multitude of protrusions and recesses, such as forexample extending teeth 21 a andflat areas 21 b in between the teeth. -
FIGS. 3A-C shows thecenter bolt 3 according to an embodiment.FIG. 3A is a side view,FIG. 3B is a top view, andFIG. 3C is a perspective view. - The
center bolt 3 has a threaded outside 32 and ahole 31 or recess in the shape of a lock, so as to allow a lock to be inserted into the hole. The threaded outside 32 is to be threadedly attached to the threaded socket 5 (shown inFIG. 5 ) by screwing (i.e. the threaded outside 32 of the center bolt matches with the threads of the threaded socket). Thecenter bolt 3 has a lateralcircular extension 32 a that has slopededges 34 to have contact with thesurface 43 of the expander 4 (FIG. 4 ). -
FIGS. 4A-C shows an example of the expanders.FIG. 4A is a side view,FIG. 4B is a top view, andFIG. 4C is a perspective view. Fourexpander sections 4 in this embodiment form a full expander that is circle shaped. The number of expander sections can vary from 1 (full circle) to any feasible number. The expander may be made of rubber, metal or other materials. The expander sections have aridge 41 that is fitted behind a ridge inside the rim. However, in some cases, depending on the shape of the inside of the rim, the sections may not have the ridge. The expander sections have a flattop area 42 that is configured to slide on center part area 16 (shown inFIG. 1 ). Theinside circumference 43 is configured to be toward the center bolt 3 (shown inFIG. 3 ). The expander sections may be held together by means of a retaining or attachment means (44 a inFIG. 8 ) (a rubber band, wire or such) so as to form a full circle expander.Area 44 may be configured to hold the attachment means. Thesurface 43 of the expander may be brought in contact with thesurface 34 of thecenter bolt 3. Due to the slope of thesurface 34, screwing the center bolt inwards (toward the wheel) may cause the expander segments to move radially. In case of an expander formed of an elastic material, the movement of the center bolt may cause the expander to expand in the radial direction. -

FIG. 9 is a perspective view of a device according to an embodiment, comprising acenter bolt 3 and a locking mechanism 6 (not mounted) for fixating thecenter bolt 3 in themain module 1. -
FIG. 10 is a perspective view of a device according to an embodiment, showing alocking mechanism 6 that is inserted in thecenter bolt 3 and attached to themain module 1 via asocket 5. -
FIG. 11 is a cross sectional view of a device according to an embodiment, illustrating an example in which the locking mechanism 6 (not inserted) can be mated with thecenter bolt 3 by means of a spline structure. - According to a preferred embodiment, the locking device of this invention comprises a locking component (main module) 1, a
locking mechanism center bolt 3, and an expander cooperating with thecenter bolt 3. - As illustrated in for example
FIGS. 1A-F , the main module may comprise acenter part 16 and a multitude of radially extendingelements 12 configured to cover lug nuts or bolts attaching the car wheel. Further, themain module 1 may comprise anopening 15 with a configured to house thecenter bolt 3. Thecenter bolt 3 may be threaded in the opening, either directly in the material of themain module 1 or indirectly via for example a threadedsocket 5. In the particular example illustrated in for exampleFIGS. 1-7 , the center bolt is connected to the main module via a threadedsocket 5 that is mounted in the main module by means of recesses andprotrusions 51 forming matching patterns on the outer side of the threadedsocket 5 and in themain module 1. - The
center bolt 3 may be threaded into the threading 53 of the threadedsocket 5 and locked by means of a locking socket or lockingcap 2. Such a lockingsocket 2 is disclosed inFIGS. 2A-C . The lockingsocket 2 may compriseprotrusions 21 a and recesses 21 b matching a correspondingstructure 52 in the threadedsocket 5 illustrated inFIG. 5A-C . Thus themain module 1, the lockingsocket 2, and thecenter bolt 3 as shown inFIGS. 1-8 can be assembled together by using the matching specific patterns and the threads. -
FIGS. 3A-C show an example of thecenter bolt 3, comprising a cylindrical part with threaded 32 outer surface that matches the threadedinner side 53 of the threadedsocket 5. Thecenter bolt 3 further comprises a hole orrecess 31 for receiving a key or wrench for tightening thecenter bolt 3 in themain module 1, and to receive the locking mechanism fixating thecenter bolt 3 in its mounted position. As illustrated in the present figures, thecenter bolt 3 also comprises a tapered or cone shapedrim 34, against which theexpander 4 may slide and expand in the radial direction as thecenter bolt 3 rotated and thus moved in the axial direction. - The
expander 4 may be formed of a plurality of annular segments placed around thecenter bolt 3, such that the taperedsurface 34 of the bolt and acorresponding surface 43 at the inner periphery of the expander slide on each other. An example of such anannular segment 4 is shown inFIGS. 4A-C andFIG. 7 . The circular segments may be held together by means of a retaining means, such as e.g. a rubber band, squeezing the segments together to a circular shape. The retaining means may be arranged in agroove 44 running around the outer periphery of the annular segments. A skilled artisan realizes that other ways to keep the pieces together are as well possible. Such other ways could include for example a wire. According to one embodiment the expander is composed of four segments but choosing any number of segments is possible. - Alternatively, the
expander 4 can be formed of an elastic material that expands in the radial direction upon compression in the axial direction (not shown in the present figures). Such a material may for example be rubber and may in some embodiments be provided in one circular piece. When the material of the expander is metal, the expander is preferably made of multiple segments to allow the required flexibility. - The assembled device, comprising the
main module 1, thecenter bolt 3 and theexpander 4, may be inserted into the rim. Additional modules, such as spacers, may be provided so as to adapt the device to the size and shape of the specific rim. In the present example, and thecorner 13 on the bottom of themain module 1 illustrated inFIG. 1 may be the only contact point with the rim. In the mounted position illustrated inFIG. 8 , theelements 12 are now covering the lug nuts on the rim. - To fasten the device to the wheel, a screw tool or key may be placed in the
lock hole 31 of the center bolt (the tool preferably has the same shape as the lock). By turning the tool, the center bolt is screwed further outwards (the threaded outside 32 of the center bolt goes against the treaded inside 53 of the threaded socket). Then thesurface 34 of the center bolt, which is in contact with thesurface 44 of theexpander 4, forces the expander(s) 4 to move outwards from the center. Simultaneously thesurface 42 of the expander slides on thesurface 16 of themain module 1. By expanding theexpanders 4, theridge 41 of the expander may be forced underneath the center of the wheel rim. If the design of the center of the rim has a ridge space or shoulder, theridge 41 of theexpander 4 may fasten the device axially behind the center of the rim. - When the module is fasted in the rim, the locking
cap 2 may be placed in the threadedsocket 5, fitting the pattern in 51 of the threadedsocket 5 and thepattern 21 of thelocking cap 2 together. Also, thehole 22 of thelocking cap 2 and thehole 31 of thecenter bolt 3 should be aligned to enable thelock 6 to fit into the holes. The lock may be inserted to prevent any rotation in any direction between thecenter bolt 3 the threadedsocket 5. - The head of the lock may rest in the
space 23. The lock may be brought into a locking state, in which it may prevent thecenter bolt 3 from rotating and at the same time securely attached to the device. This may for example be achieved by means of a disc that is arranged by the end of thelock cylinder 6 and rotated to prevent it from passing through thehole 31 in thecenter bolt 3, or by means of locking pins or balls (not shown) arranged to be moved in the radial direction to engage with thecenter bolt 3. The locking pins or balls may be released when the lock is brought back to the open state, allowing it to be withdrawn from thecenter bolt 3. - Finally, a hub cap may be placed on top of the module. To provide locking devices fitting to various designs, the
space 10 and the ridge come in different shapes and sizes. - The
lock 6 could be for example AssaAbloy's cylinder lock in Desmo and Desmo+ series; but other locks may also be used. The lock may be operable by turning a key. In another embodiment the lock is operable electronically. It may be operated with a remote controller or via a smartphone. - It will however be appreciated that the above embodiments are merely examples illustrating the present inventive concept. Other illustrative embodiments are equally conceivable. A few of them will now be described in the following, with reference to
FIGS. 9-11 . -
FIG. 9 is a perspective view of a device according to an embodiment, which may be similarly configured as the embodiments described with reference toFIGS. 1-8 . The device may comprise a body forming amain module 1, or center part, and a plurality of cases orelements 12 for at least partly covering the nuts or bolts of the wheel. The body is configured to be arranged at the hub of the wheel, such that the axis of rotation of the wheel passes through a center of the main module and the bolt ornut cases 12 extend radially outwards from the axis of rotation. - The device may further comprise a center recess or hole, in which a
center bolt 3 may be arranged in a manner that allows its axial position to be varied between a state in which the device is fixed of locked to the wheel and in a state in which the device can be removed from the wheel. The locking state may for example be achieved by allowing a rim or edge 36 of thecenter bolt 3 clamp the wheel or rim in the axial direction, or by allowing thecenter bolt 3 to radially expand anexpander 4 such that it is press fitted against the wheel or rim in the radial direction as described above in connection with previous embodiments. In one example, thecenter bolt 3 may be threaded in the main module 1 (either directly or indirectly via a socket), such that the axial position of thebolt 3 can be adjusted by rotating thebolt 3 in the threading. - As illustrated in the present figure, the
center bolt 3 may be provided with a recess or throughhole 31 which may be configured to receive or accommodate alocking mechanism 6 for preventing further rotational movement of thecenter bolt 3 in relation to themain module 1. The recess or throughhole 31 may be arranged in a center of thebolt 3 and may preferably be aligned with the axis of rotation of the wheel. Further, the inner wall of the recess or throughhole 31 may be provided with a locking structure for engaging thelocking mechanism 6 when it is inserted in thecenter bolt 3 such that thelocking mechanism 6 is secured in thecenter bolt 3 in a manner that prevents thelocking mechanism 6 from being rotated in thecenter bolt 3. This may for example be achieved by forming a plurality of recesses andprotrusions 31 in thecenter bolt 3 and allowing them to engage a corresponding structure in the locking mechanism. In the present example ofFIG. 9 , ridges or teeth forming aspline structure 35, may be used for mating thelocking mechanism 6 and thecenter bolt 6. - The
locking mechanism 6 may comprise afirst part 65 that can be mated with themain module 1 for maintaining the angular or rotational correspondence between thelocking mechanism 6 and themain module 1. This may for example be realized by means of an outer circumference that is not rotationally symmetric, and which may be fitted in a corresponding structure in themain module 1. In the example illustrated inFIG. 9 , the locking mechanism may be provided with a straight orflat edge 61 configured to engage with a similar edge in themain module 1 to achieve a rotational fixation in themain module 1. Further, thelocking mechanism 6 may comprise asecond part 66 that can be mated with thecenter bolt 6 as described above. In the present example, thesecond part 66 may comprise aspline structure 62 configured to mate with thespline structure 35 of thecenter bolt 3 to maintain the angular correspondence between thelocking mechanism 6 and thecenter bolt 6 when the locking mechanism is inserted in thecenter bolt 6. In this way, thecenter bolt 3 may be rotationally fixed to themain module 1 through the torque transferred by thelocking mechanism 6. - The
locking mechanism 6 may further comprise an axial locking means for securing thelocking mechanism 6 to the device in the locking state. The locking means may for example be formed of a pin or a ball that can be moved in the radial direction and engage with thecenter bolt 3 to prevent thelocking mechanism 6 to be removed. InFIG. 9 , an example is illustrated comprising aball 63 that can be actuated by alock cylinder 64 to fixate the locking mechanism in thecenter bolt 6. -
FIG. 10 is another perspective view of a device that may be similarly configured as the device shown inFIG. 9 . In the current view, the locking mechanism has been inserted in thecenter bolt 6.FIG. 10 also indicates the position of thesocket 2, which may be inserted in the recess or through hole of themain module 1 to strengthen the engagement between thecenter bolt 3 and themain module 1. Thesocket 2 may be rotationally or key fitted in themain module 1 by straight offlat edges 24 engaging a corresponding structure in themain module 1. Further, an inner circumference of thesocket 2 may be provided with a straight or flat edge configured to engage asimilar edge 61 of thefirst part 65 of thelocking mechanism 6 for maintaining the angular or rotational correspondence between thelocking mechanism 6 and themain module 1. -
FIG. 11 is a cross section of a device according to an embodiment, which may be similarly configured as the devices shown inFIGS. 9 and 10 . In the present figure, an example arrangement of the threadedsocket 5 is illustrated. The threadedsocket 5 may be rotationally secured in main module as described above and comprising a thread into which thecenter bolt 3 may be screwed. The relative rotational movement between thecenter bolt 3 and themain module 1 may be prevented or hindered by inserting thelocking mechanism 6, comprising afirst part 66 having an edge or rim 61 for engaging the socket 2 (and thus the main module 1) and asecond part 66 for engaging thecenter bolt 3. - The device may be manufactured from various types of materials; however, aluminum and steel are the preferred materials
- In the above the invention has mainly been described with reference to a limited number of examples. However, as is readily appreciated by a person skilled in the art, other examples than the ones disclosed above are equally possible within the scope of the inventive concept, as defined by the appended claims.
