Referring to fig. 2, the first arm 110 and the second arm 120 of the separation fork 100 are both provided with a first through hole 111, the bracket 200 is provided with a second through hole 210, and the rotating shaft 400 can sequentially pass through the first through hole 111 of the first arm 110, the second through hole 210 and the first through hole 111 of the second arm 120. It can be understood that the release fork 100 and the bracket 200 inevitably produce machining errors during manufacturing, and the self-lubricating spherical plain bearing can allow the centers of the first through hole 111 of the first arm 110, the second through hole 210 of the first arm 120 and the first through hole 111 of the second arm 120 to have slight deviations with respect to the axis of the rotating shaft 400 when the release fork 100 and the bracket 200 are assembled. And because the inner circle of self-lubricating joint bearing can rotate in a flexible way relatively the outer lane to further guarantee that axle sleeve 300 is inside can not take place the card pause.

In this embodiment, the release fork 100 and the rotating shaft 400 are in an interference fit, and the inner ring of the bearing 310 and the rotating shaft 400 are in an interference fit, so as to ensure that the release fork 100 and the rotating shaft 400 can rotate together relative to the bracket 200, and meanwhile, in this embodiment, a special fixing structure is not required to be arranged to fix the release fork 100 and the rotating shaft 400, and the rotating shaft 400 and the bearing 310, that is, the structure of the clutch release fork assembly can be simplified in this embodiment, and therefore, the manufacturing cost and the assembly difficulty of the clutch release fork assembly in this embodiment are both low.

In order to ensure that the release fork 100 and the rotating shaft 400 can flexibly rotate relative to the bracket 200 to prevent the rotating shaft 400 from being locked with the first spacer 320 and the second spacer 330, in this embodiment, the first spacer 320 and the second spacer 330 are in clearance fit with the rotating shaft 400.

In order to facilitate the maintenance of the clutch release fork assembly when the clutch release fork assembly fails, in the embodiment, the outer rings of the first spacer 320, the second spacer 330 and the bearing 310 are in transition fit with the bracket 200, so that the first spacer 320, the second spacer 330, the bracket 200 and the bearing 310 are conveniently detached.

As shown in fig. 2 and 4, in the present embodiment, the first spacer 320 and the second spacer 330 are respectively sleeved with a first sealing ring 321 and a second sealing ring 331, the first sealing ring 321 is pressed and limited between the bracket 200 and the first spacer 320, and the second sealing ring 331 is pressed and limited between the bracket 200 and the second spacer 330.

Correspondingly, since the first arm 110 can rotate relative to the first spacer 320 and the second arm 120 can rotate relative to the second spacer 330, and since the clutch release fork assembly in this embodiment can stably operate for a long time, if the O-ring seals are disposed between the first arm 110 and the first spacer 320 and the second arm 120 and between the second spacer 330, the O-ring seals between the first arm 110 and the first spacer 320 and between the second arm 120 and the second spacer 330 need to be periodically replaced, which results in higher maintenance cost of the vehicle, and in order to reduce the maintenance cost of the vehicle, in this embodiment, the ends of the first spacer 320 and the second spacer 330, which are far away from the bearing 310, are both coated with the 323 sealing layer, that is, in this embodiment, the portions where the first arm 110 and the first spacer 320 abut against each other and the portions where the second arm 120 and the second spacer 330 abut against each other are sealed by the 323 sealing layer coated on the ends of the first spacer 320 and the second spacer 330, to increase the period of vehicle maintenance.

It will be appreciated that sealing the abutment of the first arm 110 and the first spacer 320 and the abutment of the second arm 120 and the second spacer 330 by providing O-ring seals between the first arm 110 and the first spacer 320 and between the second arm 120 and the second spacer 330 will result in greater frictional resistance between the first arm 110 and the first spacer 320 and between the second arm 120 and the second spacer 330 as the first arm 110 rotates relative to the first spacer 320 and the second arm 120 rotates relative to the second spacer 330, thereby affecting clutch performance, and this can be avoided by sealing the abutment of the first arm 110 and the first spacer 320 and the abutment of the second arm 120 and the second spacer 330 by the sealing layer 323 applied to the ends of the first spacer 320 and the second spacer 330.

Furthermore, the sealing layer 323 is a vulcanized non-metallic material to improve the hardness and wear resistance of the sealing layer 323, so that not only can a large frictional resistance generated between the first support arm 110 and the first spacer 320 and between the second support arm 120 and the second spacer 330 be avoided when the first support arm 110 rotates relative to the first spacer 320 and the second support arm 120 rotates relative to the second spacer 330, but also the loss of the sealing layer 323 can be reduced, thereby further increasing the cycle of vehicle maintenance.

In order to further prevent external impurities such as large particles, dust and the like from entering the shaft sleeve 300 from between the rotating shaft 400 and the first spacer 320 and between the rotating shaft 400 and the second spacer 330, referring to fig. 1 and 4, in this embodiment, a third sealing ring 410 and a fourth sealing ring 420 are respectively sleeved on the side of the rotating shaft 400 located on the first support arm 110 far away from the second support arm 120 and the side of the second support arm 120 far away from the first support arm 110, and the third sealing ring 410 and the fourth sealing ring 420 are respectively attached to the first support arm 110 and the second support arm 120.

Further, in this embodiment, the third seal ring 410 and the fourth seal ring 420 are preferably metal seal gaskets, so that the third seal ring 410 and the fourth seal ring 420 can be fixed to the rotating shaft 400 when not being subjected to a pressing force, and can be respectively tightly attached to the side walls of the opposite sides of the first support arm 110 and the second support arm 120, thereby effectively preventing impurities such as large particles, dust, and the like from entering the opposite sides of the first support arm 110 and the second support arm 120 from the gap between the hole wall of the first through hole 111 on the first support arm 110 and the rotating shaft 400 and the gap between the hole wall of the first through hole 111 on the second support arm 120 and the rotating shaft 400.
