Description

Pneumatic cog type clutch

Technical Field

The invention relates to the technical field of clutches, in particular to a pneumatic cog type clutch.

Background

The clutch is a component of the drive train, by means of which the drive input is connected to the drive output and, if necessary, interrupts the transmission of power. The clutch matched with the mechanical transmission is divided into a pull type clutch and a push type clutch according to the movement direction of the clutch, the pull type clutch is more and more widely applied due to the characteristics of the pull type clutch, a clutch release fork is used as a key part, when a cylinder piston extends out to push the release fork, the cylinder piston acts on one end of the clutch release fork, a release fork shaft is used as a fulcrum to enable the release fork to slide along the axial direction, the other end of the release fork pushes an upper ratchet to enable the clutch to be separated, when the cylinder piston contracts, the shift fork loses support, a pressure spring applies downward pressure to an upper ratchet wheel to enable the upper ratchet wheel to move downward along a spline shaft and be jointed with a.

The existing clutch has a complex structure, cannot meet the use requirements more and more, cannot effectively transmit power, causes the phenomena of clutch slipping, friction plate burning loss and the like, and some clutches also need to be maintained by adding lubricating grease regularly, and the volume of the clutch also needs to be correspondingly increased along with the increase of input power. The clutches are not suitable for application scenarios with limited space but larger required power, or intelligent combination of a plurality of power output shafts driven by single power input, and the like. To this end, we propose a pneumatic cog type clutch to solve the above existing problems.
