[0018] Referring to figure 1 and figure 2, in one aspect of the present invention, a device 100 for assembly of a bead lock 30 on a tyre 10 is disclosed. The device 100 comprises a press tool 110, a pressing ring 120, a bottom plate 122, a top plate 124, a hydraulic jack 126, plurality of lock pins 130 and a plurality of studs 140. The device 100 is configured to press the tyre 10 to create gap between the tyre 10 and the wheel rim 20 to position a lock ring 40 in the gap. During assembly, the bead lock 30 is inserted in the tyre 10 and the tyre 10 with bead lock 30 is assembled on the wheel rim 20. Further the wheel rim 20 is positioned on a flat surface. The pressing ring 120 is configured to be engaged with the tyre 10 where the tyre 10 needs to be pressed. The bottom plate 122 is mounted under the wheel rim 20 and locked by the plurality of studs 140. The press tool 110 comprises a base 112 and a plurality of legs 114 wherein the plurality of legs 114 are configured to be mounted on the pressing ring 120. In an embodiment, the pressing ring 120 may be integrated with the press tool 110 through the plurality of legs 114. The hydraulic jack 126 is mounted on the base 112 of the press tool 110. Further the top plate 124 is adapted to be resting on the hydraulic jack 126 and is configured to be slidably mounted on the plurality of studs 140. Further a plurality of locking pins 130 are provided to be engaged with the plurality of studs 140 to restrict upward motion of the top plate 124.
[0019] The wheel rim comprises a plurality of holes to receive the plurality of studs 140 for locking of the bottom plate 122.
[0020] The device 100 may be configured to be stored in the vehicle tool box for easy retrieval and storage. Further the hydraulic jack 126 of the device 100 may be used for lifting of the vehicle for maintenance or breakdown purposes such as changing the tyre 10.
[0021] During assembly operation, the hydraulic jack 126 is operated to generate pressure on the tyre 10 and thereby creating a gap between the tyre 10 and the wheel rim 20 to insert the lock ring 40 in the gap. Hence the whole assembly of the tyre 10, the bead lock 30 and the wheel rim 20 is locked by the lock ring 40 with the help of the device 100.
[0022] In another embodiment, a method for assembly of bead lock on a tyre by the device 100 is disclosed. The method comprises steps of: locking the bottom plate 122 under the wheel rim 20 by the plurality of studs 140; engaging the pressing ring 120 on the tyre 10; mounting the press tool 110 on the pressing ring 120; mounting the hydraulic jack 126 on the base 112 of the press tool 110; mounting, slidably, the top plate 124 on the plurality of studs 140 wherein the top plate 124 rests on the hydraulic jack 126; locking upward motion of the top plate 124 by engaging a plurality of locking pins 130 with the plurality of studs 140; operating the hydraulic jack 126 to generate pressure on the tyre 10 and thereby creating a gap between the tyre 10 and the wheel rim 20; and inserting the lock ring 40 in the gap.
[0023] Therefore the installation of the lock ring 40 can be performed easily with the device 100 with reduced human effort to press the wheel assembly.
