Description

A coupling device for securing a vehicle component to a longitudinal frame rail of a vehicle frame FIELD OF THE INVENTION AND PRIOR ART The present invention relates to a coupling device according to the preamble of claim 1.
A vehicle in the form of a truck often has a larger vehicle component mounted to a longitudinal frame rail of the vehicle frame. Thus, there is a need for a convenient and safe manner of securing a larger vehicle component to a longitudinal frame rail of a vehicle frame of a truck or other type of heavy vehicle. It should also be possible to remove the vehicle component from the vehicle frame in a quick and convenient manner at a later moment, for instance when the vehicle component is to be subjected to maintenance, repair or replacement.
It is previously known to secure a cylindrical vehicle component in the form of a tank or the similar to a longitudinal frame rail of a vehicle frame of a truck or other type of vehicle by means of holding brackets and straps, wherein the holding brackets are fixed to the longitudinal frame rail, for instance by means of bolts, and the cylindrical vehicle component is fastened to the holding brackets by the straps. However, there are some vehicle components, such as for instance heavy and non-cylindrical electric energy storage devices for hybrid vehicles, which are not suitable for mounting to a vehicle frame by means of such holding brackets and straps.
A vehicle component of the last-mentioned type may as an alternative be supported from below by being placed on horizontally extending support arms of holding brackets which are fixed to a longitudinal frame rail of a vehicle frame of a truck, as shown in WO 2015/137869 A1. However, with this solution it will be rather difficult to remove the vehicle component from the vehicle frame if the upper part of the vehicle component is covered by a cargo body, for instance in the form of a box body, flatbed body or refuse collection body, which is fixedly mounted to the vehicle frame.
OBJECT OF THE INVENTION The object of the present invention is to provide a new and favourable coupling device which is suitable for use in the mounting of a vehicle component to a longitudinal frame rail of a vehicle frame at a vehicle manufacturing plant and which also makes it possible to remove the vehicle component from the vehicle frame in a convenient manner at a later moment, for instance when the vehicle component is to be subjected to maintenance, repair or replacement.
SUMMARY OF THE INVENTION According to the present invention, the above-mentioned object is achieved by a coupling device having the features defined in claim 1.
The coupling device of the present invention comprises: - a first coupling part, which comprises a base member to be fixed to a vertical side wall of a longitudinal frame rail of a vehicle frame, wherein the base member has an upper end, which is configured to face upwards when the base member is fixed to said side wall, and an opposite lower end; - a second coupling part, which is to be fixed to a vehicle component and which is configured for releasable engagement with said base member; and - a third coupling part, which is releasably securable to said base member at the upper end thereof by means of a set of rotatable first fastening elements and which is securable to the second coupling part by means of a set of rotatable second fastening elements, wherein the base member is configured to support the second coupling part via the third coupling part when the second coupling part has been secured to the third coupling part and the third coupling part has been secured to the base member.
Each one of the first and second fastening elements is provided with a head configured for engagement with a torque tool, wherein each second fastening element has an upwardly facing head to thereby allow a torque tool to be engaged with the head from above when the second fastening element is to be rotated in order to secure the third coupling part to the second coupling part, and wherein each first fastening element has a downwardly facing head to thereby allow a torque tool to be engaged with the head from below when the first fastening element is to be rotated in a first rotary direction in order to release the third coupling part from the base member or in an opposite rotary direction in order to secure the third coupling part to the base member.
Furthermore, the first coupling part comprises a locking member, which is moveable in relation to the base member between a releasing position, in which the locking member allows the second coupling part to be moved into and out of engagement with the base member, and a locking position, in which the locking member keeps the second coupling part locked to the base member. The first coupling part also comprises a vertically extending operating shaft, which is rotatably mounted to the base member, wherein the locking member is connected to the operating shaft and moveable between the releasing position and the locking position by rotation of the operating shaft, and wherein the operating shaft at its upper end has an upwardly facing first socket and at its lower end has a downwardly facing second socket, said first and second sockets being configured for engagement with a torque tool to thereby allow a torque tool to be engaged with the first socket from above or with the second socket from below when the operating shaft is to be rotated in order to move the locking member between said positions.
The base member of the first coupling part is to be fixed to a longitudinal frame rail of a vehicle frame, with the third coupling part secured to the base member at the upper end thereof, and the second coupling part is to be fixed to a vehicle component, before the mounting of the vehicle component to the vehicle frame. When the vehicle component is to be mounted to the vehicle frame, the vehicle component is moved towards the first coupling part together with the second coupling part so as to bring the second coupling part into engagement with the base member of the first coupling part, wherein the second coupling part is made to rest against the third coupling part. Thereafter, the second coupling part is secured to the third coupling part by means of the second fastening elements and the operating shaft is rotated to move the locking member into the locking position in order to secure the second coupling part to the base member of the first coupling part and thereby secure the vehicle component to the vehicle frame. The required rotation of the second fastening elements and the operating shaft during the mounting of the vehicle component to the vehicle frame may be effected by means of a torque tool from above, which implies that the coupling device is suitable for use in many modern truck manufacturing plants. When the vehicle component is to be removed from the vehicle frame at a later moment, the third coupling part is released from the base member of the first coupling part by rotation of the first fastening elements and the operating shaft is rotated to move the locking member into the releasing position, whereupon the second and third coupling parts, while remaining secured to each other, may be moved away from the first coupling part together with the vehicle component. The required rotation of the first fastening elements and the operating shaft during the removal of the vehicle component from the vehicle frame may be effected by means of a torque tool from below, which is favourable if the vehicle is provided with a cargo body which is fixedly mounted to the vehicle frame and projects laterally over the coupling device and the vehicle component. During and after the removal of the vehicle component from the vehicle frame, the second fastening elements keep the third coupling part secured to the second coupling part. When the vehicle component is to be remounted to the vehicle frame, the vehicle component is moved towards the first coupling part together with the second and third coupling parts so as to bring the second and third coupling parts into engagement with the base member of the first coupling part, wherein the third coupling part is made to rest against the base member of the first coupling part. Thereafter, the third coupling part is secured to the base member of the first coupling part by means of the first fastening elements and the operating shaft is rotated to move the locking member into the locking position in order to secure the second coupling part to the base member of the first coupling part and thereby secure the vehicle component to the vehicle frame. The required rotation of the first fastening elements and the operating shaft during the remounting of the vehicle component to the vehicle frame may be effected by means of a torque tool from below.
Further advantages as well as advantageous features of the coupling device of the present invention will appear from the description following below and the dependent claims.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION A coupling device 1 according to an embodiment the present invention is illustrated in Figs 1-14. The coupling device 1 is to be used for securing a vehicle component 2 to a longitudinal frame rail 3 of a vehicle frame, for instance on a truck or other type of heavy vehicle. In the illustrated example, the vehicle component 2 has the form of a holding frame which is intended to carry an electric energy storage device for a hybrid vehicle. However, the coupling device 1 could be used for securing also other types of vehicle components to a vehicle frame.
The coupling device 1 comprises a first coupling part 10, which comprises a base member 11 to be fixed to a vertical side wall 4 of the longitudinal frame rail 3 on the outer side of the side wall 4. The base member 11 has an upper end, which is configured to face upwards when the base member 11 is fixed to the side wall 4, and an opposite lower end, which is configured to face downwards when the base member 11 is fixed to the side wall 4. In the illustrated embodiment, the base member 11 is fixed to the side wall 4 by means of bolts 12, wherein the bolt shaft of each one of the bolts 12 extends through an associated horizontal bolt hole 13 (see Fig 12) in the base member 11 and through a corresponding bolt hole in the side wall 4. A plate 5 (see Fig 2) may be arranged between the heads 14 of the bolts 12 and the inner side of the side wall 4 in order to distribute the load transferred from the bolts to the side wall.
The coupling device 1 further comprises a second coupling part 30, which is to be fixed to the vehicle component 2 and which is configured for releasable engagement with the base member 11 of the first coupling part 10.
The coupling device 1 also comprises a third coupling part 40, which is releasably securable to the base member 11 of the first coupling part 10 at the upper end thereof and which is also securable to the second coupling part 30. The base member 11 is configured to support the second coupling part 30 via the third coupling part 40 when the second coupling part 30 has been secured to the third coupling part 40 and the third coupling part has been secured to the base member 11. The third coupling part 40 is releasably securable to the base member 11 by means of a set of rotatable first fastening elements 15 (see Fig 11) and securable to the second coupling part 30 by means of a set of rotatable second fastening elements 35 (see Fig 12). Each one of the first and second fastening elements 15, 35 is provided with a head 16, 36 configured for engagement with a torque tool (not shown).
In the illustrated embodiment, the first set of fastening members 15 comprises two fastening members and the second set of fastening members 35 also comprises two fastening members.
However, the number of fastening members 15, 35 in each set may also be more than two if so desired.
In the illustrated embodiment, the heads 16, 36 of the first and second fastening elements 15, 35 have an external hexagonal shape configured for engagement with an adjustable wrench or socket wrench. As an alternative, each head 16, 36 could be provided with an internal hexagonal socket configured for engagement with an Allen key. The heads 16, 36 could also have any other suitable interface configured for engagement with a corresponding interface on the torque tool.
Each first fastening element 15 has a downwardly facing head 16 to thereby allow a torque tool to be engaged with the head 16 from below when the first fastening element 15 is to be rotated in a first rotary direction in order to release the third coupling part 40 from the base member 11 or in an opposite second rotary direction in order to secure the third coupling part 40 to the base member 11. Each first fastening element 15 is preferably designed as a screw with an elongated screw shaft 17 (see Fig 11) , which is fixed to the head 16 of the fastening element and which has an external thread 18 configured for engagement with a corresponding internal thread 48 provided in a downwardly open screw hole 47 in the third coupling part 40. The base member 11 of the first coupling part 10 is provided with vertical through holes 19 for receiving the screw shafts 17 of the first fastening elements 15, wherein these through holes 19 are aligned with the screw holes 47 in the third coupling part 40 when the third coupling part is secured to the base member 11. The screw shaft 17 of each first fastening element 15 preferably also has an external thread 20 configured for engagement with an internal thread 21 provided in the associated through hole 19 in the base member 11 to thereby prevent the first fastening element 15 from falling down to the ground when the screw shaft 17 has been unscrewed from the associated screw hole 47 in the third coupling part 40 in connection with a release of the third coupling part 40 from the base member 11. In the illustrated embodiment, the head 16 of each first fastening element 15 abuts against a downwardly facing shoulder 22 on the base member 11 when the screw shaft 17 has been properly screwed into the associated screw hole 47 in the third coupling part 40.
Each second fastening element 35 has an upwardly facing head 36 to thereby allow a torque tool to be engaged with the head 36 from above when the second fastening element 35 is to be rotated in order to secure the third coupling part 40 to the second coupling part 30. Each second fastening element 35 is preferably designed as a screw with an elongated screw shaft 37 (see Fig 12), which is fixed to the head 36 of the fastening element and which has an external thread 34 configured for engagement with a corresponding internal thread 44 provided in an upwardly open screw hole 45 in the third coupling part 40.
In the illustrated embodiment, the second coupling part 30 comprises a horizontally extending bracket 31, which is provided at the upper end of the second coupling part. The bracket 31 is configured to extend over the upper end of the base member 11 of the first coupling part 10 when the second coupling part 30 is in engagement with the base member 11, to thereby allow the third coupling part 40 to be located in a space between the upper end of the base member 1 1 and the bracket 31. The bracket 31 is provided with vertical through holes 32 (see Figs 4 and 5) for receiving the screw shafts 37 of the second fastening elements 35 to thereby allow the third coupling part 40 to be secured to the bracket 31 by means of the second fastening elements 35. In the illustrated embodiment, the heads 36 of the second fastening elements 35 abut against an upper surface of the bracket 31 when the screw shafts 37 have been properly screwed into the associated screw holes 45 in the third coupling part 40.
In the illustrated embodiment, two stop members 41a, 41 b (see Figs 4, 5 and 7) are provided on the upper side of the third coupling part 40. Each one of these stop members 41a, 41 b is configured for engagement with a shoulder 33 on the abovementioned bracket 31 in order to prevent the bracket 31 from sliding off the third coupling part 40 when the bracket 31 has been brought into engagement with the third coupling part 40, as illustrated in Fig 5.
The first coupling part 10 comprises a locking member 23 and a vertically extending operating shaft 24. The locking member 23 is moveable in relation to the base member 11 between a releasing position (see Figs 6a, 6b, 13b and 13c), in which the locking member 23 allows the second coupling part 30 to be moved into and out of engagement with the base member 11, and a locking position (see Figs 6c, 10 and 13a), in which the locking member 23 keeps the second coupling part 30 locked to the base member 11. The operating shaft 24 is rotatably mounted to the base member 11. The locking member 23 is connected to the operating shaft 24 and moveable between the releasing position and the locking position by rotation of the operating shaft 24. The operating shaft 24 is rotatable in a first rotary direction in order to move the locking member 23 from the releasing position to the locking position and in an opposite second rotary direction in order to move the locking member 23 from the locking position to the releasing position.
The operating shaft 24 has an upwardly facing first socket 25a (see Fig 9) at its upper end and a downwardly facing second socket 25b at its lower end, each one of these sockets 25a, 25b being configured for engagement with a torque tool (not shown) to thereby allow a torque tool to be engaged with the first socket 25a from above or with the second socket 25b from below when the operating shaft 24 is to be rotated in order to move the locking member 23 between the releasing and locking positions.
As illustrated in Figs 4 and 9, the third coupling part 40 is provided with a vertical through hole 49 or recess which is configured to be in alignment with the operating shaft 24 when the third coupling part 40 has been secured to the base member 11, and the bracket 31 is provided with a corresponding through hole 39 or recess which is configured to be in alignment with the vertical through hole 49 or recess in the third coupling part 40 when the bracket 31 has been secured to the third coupling part 40, to thereby allow the first socket 25a to be accessible via this through hole 39 or recess in the bracket 31 and this through hole 49 or recess in the third coupling part 40 when the second coupling part 30 and been secured to the base member 11.
In the illustrated embodiment, the first and second sockets 25a, 25b have an external hexagonal shape configured for engagement with an adjustable wrench or socket wrench. As an alternative, each socket 25a, 25b could be provided with an internal hexagonal socket configured for engagement with an Allen key. The sockets 25a, 25b could also have any other suitable interface configured for engagement with a corresponding interface on the torque tool.
In the illustrated embodiment, the operating shaft 24 extends through a vertical through hole 26 in the base member 1 1, as illustrated in Fig 9, wherein the operating shaft 24 is provided with an external thread 27 which is in engagement with a corresponding internal thread 28 provided in said through hole 26. The operating shaft is moveable axially upwards in the through hole 26 by rotation of the operating shaft 24 in a first rotary direction and axially downwards in the through hole 26 by rotation of the operating shaft 24 in an opposite second rotary direction, the locking member 23 being fixed to the operating shaft 24 so as to move vertically together with the operating shaft in connection with the rotation thereof. In the illustrated example, the locking member 23 is arranged at the lower end of the base member 11 and fixed to the operating shaft 24 at the lower end thereof. The base member 11 is provided with a stop member 11a (see Figs 3 and 6a) which is configured to be in contact with the locking member 23 in order to prevent the locking member from rotating in relation to the base member 11 in connection with a rotation of the operating shaft 24. The locking member 23 is vertically slidable along the stop member 11a when it is moved between the locking and releasing positions.
As an alternative (not illustrated), the operating shaft 24 could be rotatably mounted to the base member 11 while being fixed in axial position in relation to the base member 11, wherein the locking member 23 would be provided with an internal thread engaged with a corresponding external thread on the operating shaft 24 to thereby allow the locking member 23 to move vertically upwards along the operating shaft 24 when the operating shaft is rotated in a first rotary direction and vertically downwards along the operating shaft 24 when the operating shaft is rotated in an opposite second rotary direction.
The locking member 23 preferably has the form of a horizontal beam, but it may of course also be designed in any other suitable manner.
In the illustrated embodiment, the second coupling part 30 is provided with two horizontally extending locking arms 38 arranged in parallel with each other, wherein the locking member 23 is configured to be in engagement with the locking arms 38 when the locking member 23 is in the locking position to thereby keep the second coupling part 30 locked to the base member 11. As an alternative, the second coupling part 30 could be provided with only one such locking arm or more than two such locking arms. In the illustrated example, each locking arm 38 is configured to be received in a recess 29 (see Fig 3) in the base member 11 when the second coupling part 30 is in engagement with the base member 11. Each locking arm 38 is with advantage hook-shaped and the locking member 23 is preferably provided with a bevelled wedging surface 23a configured for engagement with a corresponding bevelled wedging surface 38a on each locking arm 38 (see Figs 6a-6c), to thereby allow the locking member 23 to pull the second coupling part 30 tightly against the base member 11 when the locking member 23 is moved upwards into the locking position. As an alternative, the interface between the locking arm and the locking member could have any other suitable configuration.
When a vehicle component 2 is to be secured to a longitudinal frame rail 3 of a vehicle frame by means of the coupling device 1, the base member 11 of the first coupling part 10 is first secured to a vertical side wall 4 of the longitudinal frame rail 3 and the third coupling part 40 is secured to the base member 1 1, at the upper end thereof, by means of the first fastening elements 15. Furthermore, the second coupling member 30 is secured to the vehicle component 2, for instance by means of bolts. Thereafter, the vehicle component 2 is moved in a horizontal direction towards the side wall 4 in such a manner that the second coupling part 30 is moved from the position illustrated in Fig 6a to the position illustrated in Fig 6b, wherein the bracket 31 is moved over the upper end of the third coupling part 40 and the locking arms 38 are moved into the associated recesses 29 in the base member 11. The stop members 41a, 41 b on the third coupling part 40 now prevents the bracket 31 from sliding off the third coupling part 40 and thereby keeps the second coupling part 30 in contact with the base member 11. Thereupon, the second fastening elements 35 are inserted into the through holes 32 in the bracket 31 and screwed into the upwardly open screw holes 45 in the third coupling part and the operating shaft 24 is rotated in the above-mentioned first rotary direction in order to move the locking member 23 from the releasing position illustrated in Fig 6b to the locking position illustrated in Fig 6c. The second coupling part 30 is hereby firmly secured to the base member 11, which in its turn implies that the vehicle component 2 is firmly secured to the longitudinal frame rail 3 by the coupling device 1. The rotation of the second fastening elements 35 and the rotation of the operating shaft 24 required in order to secure the second coupling part 30 to the base member 11 may be effected by means of a torque tool from above.
Figs 13a-13c illustrate the steps required for a later removal of the vehicle component 2 from the longitudinal frame rail 3, for instance in a situation when the vehicle component 2 or an object mounted to the vehicle component is to be subjected to maintenance, repair or replacement. In a first step, the first fastening members 15 are rotated in order to be unscrewed from the downwardly open screw holes 47 in the third coupling part 40 and the operating shaft 24 is rotated in the above-mentioned second rotary direction in order to move the locking member 23 from the locking position illustrated in Fig 13a to the releasing position illustrated in Fig 13b. The second coupling part 30 may now be moved in a horizontal direction away from the base member 11 together with the third coupling part 40, as illustrated in Fig 13c, which in its turn implies that the vehicle component 2 is released from the longitudinal frame rail 3. The rotation of the first fastening elements 15 and the rotation of the operating shaft 24 required in order to release the second coupling part 30 from the base member 11 may be effected by means of a torque tool from below. The vehicle component 2 may subsequently be remounted to the longitudinal frame rail 3 by performing the steps illustrated in Figs 13a-13c in the opposite order, wherein the rotation of the first fastening elements 15 and the rotation of the operating shaft 24 required in order to secure the second coupling part 30 to the base member 11 may be effected by means of a torque tool from below.
The invention is of course not in any way restricted to the embodiments described above. On the contrary, many possibilities to modifications thereof will be apparent to a person with ordinary skill in the art without departing from the basic idea of the invention such as defined in the appended claims.
