Embodiment 1

[0024] Embodiment one, see figure 1 , a clutch hub removal tool provided with a handle glove for remanufacturing an automatic transmission, including a pull rod 1 . The upper end of the pull rod 1 is provided with a grip rod 3 . Grip bar 3 has two. Two holding rods 3 are symmetrically distributed on both sides of the pull rod 1 . 3 sets of grip bars are provided with handle gloves 31 . The handle glove 31 is a rubber sheath. The handle glove 31 is detachably sheathed on the handle bar 3 . The end surface of the lower end of the pull rod 1 is provided with an accommodating hole 11 which can be sleeved on the rotating shaft. The wall of the receiving hole 11 is provided with a through hole 12 that can be aligned with the slot when the rotating shaft is inserted into the receiving hole. The through hole 12 is a threaded hole. A bayonet pin 2 that can be inserted into the bayonet is screwed into the through hole 12 . Bayonet 2 is a jacking bolt.

Embodiment 2

[0027] Embodiment two, the difference with embodiment one is:

[0028] see image 3 , a clamping and fixing structure 5 is also provided. The clamping and fixing structure 5 includes a sliding hole 51 , a clamping block 52 slidingly and sealingly connected to the sliding hole, a piston chamber 53 , a pressurizing piston 54 slidingly and sealingly connected to the piston chamber, and a heating mechanism 55 . The sliding hole 51 is disposed on a wall of the receiving hole 11 . There are two sliding holes 51 . Two sliding holes 13 are distributed along the circumferential direction of the tie rod 1 . The piston chamber 53 is disposed on the tie rod 1 . There is only one piston chamber 53. The piston chamber 53 is in communication with all the slide holes 51 . The press piston 54 is provided with a press rod 541 . The pressing rod 541 protrudes from the end of the tie rod 1 . A closed cavity 531 is formed between the pressurizing piston 54 and the clamping block 52 . A ti...

Embodiment 3

[0031] Embodiment three, the difference with embodiment two is:

[0032] see Figure 4, An elastic force adjustment mechanism 8 is provided between the grip bar 3 and the handle cover 31 . The elastic force adjustment mechanism 8 includes a base pipe 81 , a clamping layer 82 and a preload adjustment structure 83 . The base tube 81 is sheathed outside the handle bar 3 . The base pipe 81 is passed through the handle glove 31 . The clamping layer 82 is composed of several friction strips 821 . The friction strips 821 are distributed along the circumferential direction of the base pipe 81 . The friction strip 821 is provided with a plurality of slide bars 822 axially distributed along the radial extension of the base pipe. The sliding rod 822 slides through the base tube 81 . The inner end of the sliding rod 822 is provided with a third spring 823 . The third spring 823 drives the friction strip to abut against the handle glove 31 through the slide bar. The outwardly movin...

Abstract

The invention relates to the technical field of remanufacturing of automatic transmissions, in particular to a clutch hub demounting tool provided with a handle sleeve and used for remanufacturing of an automatic transmission. A clutch hub comprises a clutch hub body and a rotating shaft penetrating into the clutch hub body in a pluggable manner. The circumferential face of the part, located outside the clutch hub, of the rotating shaft is provided with a ring-shaped clamping ring. The clutch hub demounting tool is characterized by comprising a pull rod; one end of the pull rod is provided with a handheld rod; the end face of the other end of the pull rod is provided with a containing hole where the rotating shaft can be sleeved; the hole wall of the containing hole is provided with a through hole which can be aligned with the clamping groove when the rotating shaft is inserted into the containing hole; and the handheld rod is sleeved with the handle sleeve. The clutch hub demounting tool provided with the handle sleeve and used for remanufacturing of the automatic transmission can be used for demounting the rotating shaft of the clutch hub conveniently and stably with low noise, and the problems that demounting of the rotating shaft on the clutch hub is high in noise and not convenient, and the clutch hub is liable to be damaged are solved.

Description

technical field [0001] The invention relates to the technical field of automatic transmission remanufacturing, in particular to a clutch hub dismantling tool provided with a handle glove for automatic transmission remanufacturing. Background technique [0002] The clutch hub is a part of the input clutch of the automatic transmission. The clutch hub includes a clutch hub body and a rotating shaft detachably inserted through the clutch hub body. An annular slot is provided on the peripheral surface of the rotating shaft outside the clutch hub. Automatic transmission rebuilds sometimes require the shaft to be removed from the clutch hub body. In the existing automatic transmission rebuilding process, dismounting the lower clutch hub is achieved by hitting the end of the rotating shaft. It is noisy and inconvenient to disassemble the clutch hub by beating, and it is easy to damage the clutch hub body. Contents of the invention [0003] The invention provides a clutch hub di...
