Drive shaft removal tool structure

The creation system is related to a transmission shaft removal tool structure, in particular, the transmission shaft removal tool structure can be pulled by a hammer strike or a puller to disengage the brake disc seat from the drive shaft.

As previously known by us, the conventional drive shaft removal tool structure, such as Taiwan Patent Application No. 099205610, Bulletin No. M387749, patent name automobile drive shaft disassembly auxiliary tool set, is based on: an automobile drive shaft disassembly assistant The tool set is specially designed to assist in disassembling or assembling the shaft end portion of the automobile transmission shaft and the disc mounting seat. The transmission shaft dismounting tool structure comprises: a screw having a threaded body and the shaft is separated from the two ends. a detaching cover portion includes a cover portion, a flange portion protruding from an outer side of the cover portion, and a through hole formed in a center of the cover portion. The screw hole can be screwed into the screw thread of the screw, and the flange portion is provided with a locking through groove; an assembly resisting frame is defined in a meandering plate shape to define a top plate portion and the top plate a second abutting portion extending from the two sides, wherein the top plate portion has a slot in the center for the screw to pass through; the assembly rotary nut includes a belt rotating portion and a rotatable pressing portion Department and the group The center of the rotating nut is provided with a through hole for screwing the screw thread of the screw, and the rotatable pressing portion is for abutting against the top plate portion of the assembly resisting frame; The inner end of the cylinder is provided with a screw assembly screw hole and a transmission shaft assembly screw hole, wherein the screw assembly screw hole is used for the screw end combination of the screw end, and the assembly screw body is externally It is provided with a rotating part.

However, the structure of the patent is missing: the second portion to the fourth figure are shown, the driven portion 11 of the screw 10 is rotated, and the thread of the screw 10 and the through hole of the disassembling cover 20 are used. The screwing engagement of 23 causes the disassembling cover 20 to be relatively reversely actuated, thereby causing the disc mounting seat 06 to be displaced upwardly, and the disc assembled at the shaft end 051 of the automobile transmission shaft 05 can be disassembled. In the installation of the seat 06, the main purpose of removing the disc mounting seat 06 is to replace the dust jacket on the automobile transmission shaft 05, but the dust jacket of the automobile transmission shaft 05 is damaged and needs to be replaced for a longer period. The time between the disc mounting seat 06 and the shaft end portion 051 of the transmission shaft 05 may be stuck due to the long time. When the screw 10 is rotated, it is difficult to disengage the disc mounting seat 06 and the transmission shaft 05. .

In view of the lack of structure of the above patents, the creator has been engaged in the manufacturing and design experience of related industries for many years, and finally has a product that can solve the drawbacks of the drive shaft disassembly tool structure.

The utility model is only the operating structure of the rotating screw. The drive shaft dismounting tool structure of the present invention can be pulled by the hammer striking or the puller to disengage the brake disc seat from the transmission shaft.

A transmission shaft removal tool structure includes: a first body, the first system is provided with a convex portion, the convex portion is provided with a first screwing portion, and the first screwing portion is formed in a through hole shape. The first system has a plurality of first through slots and a second through slots. The first through slots and the second through slots are in the shape of long slots. The number of the first slots is four, and the second through The number of slots is five; the plurality of screwing members, the number of the screwing members is four or five, and the number of the plurality of screwing members is matched with the first through slot or the second through slot of the first body. The plurality of screwing members are disposed at the first through groove or the second through groove; and an adjusting member is provided with the second screw The second screwing portion is screwed to the first screwing portion, the adjusting member is provided with abutting portion, and the adjusting member is provided with a through groove; a rod body having one end of the rod body The assembly system is disposed in the through slot.

Because the first tooth portion of the drive shaft and the second tooth portion of the brake disc holder are tightly inserted and generally dead for a long time, the end of the rod body is knocked with various hammers. After the strut is struck, the striking force is transmitted to the end of the transmission shaft, and the brake disc seat is also subjected to the striking force, and the stuck state between the first tooth portion and the second tooth portion is struck. The force acts to destroy the stuck state, so that the brake disc seat is gradually removed from the drive shaft by the tapping force. The first system is screwed with an adjusting member, so that the creative transmission shaft dismounting tool structure can be combined with the puller to make the rotating member abut against the end of the rod, and the pulling member pulls the adjusting member, the adjusting The piece drives the displacement of the first body and the brake disc seat, so that the brake disc seat is disengaged from the drive shaft. The creation system can use the hammer to strike the end of the rod body or the puller to abut the end of the rod body to disengage the brake disc seat from the transmission shaft. The upper system has two operation modes, generally speaking, The first tooth portion and the second tooth portion are generally stuck together for a long time, so that the user can first hit the end of the rod body by using the hammer body to break the card between the first tooth portion and the second tooth portion. In the dead state, the puller is used to slowly pull the first body and the brake wheel holder. The hammer and the puller have the best operation mode.

In order to enable the members of the Board and those skilled in the art to fully understand the effects of this creation, the structure and composition of the creation are described in conjunction with the drawings and drawings, but the following are only used to explain the implementation of this creation. For example, it is not intended to impose any form of restriction on this creation. Any modification made in the spirit of this creation should still fall within the scope of this creation.
