The clutch outer hub 11 is directly and fixedly connected with the connecting plate 13, so that the clutch outer hub 11 and the sleeve 12 can be reliably and stably supported, the structure of the connecting plate 13 can be simplified, and the production and processing cost of the connecting plate 13 can be reduced; the joints of the clutch outer hub 11, the sleeve 12 and the connecting plate 13 are connected by only one key, so that the degree of eccentricity of the clutch outer hub 11, the sleeve 12 and the connecting plate 13 during high-speed running of a vehicle can be reduced, the effects of reducing vibration and noise are achieved, and the driver and passengers can feel better; through the mode that sets up with the terminal surface butt of the connecting plate 13 of the outer hub 11 fixed connection of clutch and sleeve 12, can make the tip of sleeve 12 obtain more reliable supporting effect to can restrict the jumping amount of sleeve 12 tip effectively, simultaneously, set up like this and also can make sleeve 12 and the outer hub 11 key-type connection of clutch fit clearance suitably increase, thereby reduce sleeve 12's the assembly degree of difficulty, improve assembly work's efficiency.
In some embodiments, the clutch outer hub 11 includes a first key connection portion 111, the sleeve 12 includes a second key connection portion 121, the first key connection portion 111 is keyed to the second key connection portion 121, and the first key connection portion 111 and the second key connection portion 121 have the same length. Setting the lengths of the first key connecting portion 111 and the second key connecting portion 121 to be the same ensures that the clutch outer hub 11 and the sleeve 12 are reliably in transmission connection, and also prevents the first key connecting portion 111 and the second key connecting portion 121 from intruding into too much space in the transmission case and affecting the arrangement work of other parts.
In a further embodiment, the first key connection portion 111 is of an internal spline structure, the second key connection portion 121 is of an external spline structure, the first key connection portion 111 and the second key connection portion 121 are in spline connection, and the clutch outer hub 11 and the sleeve 12 which are in spline connection can further ensure the reliability of transmission connection, and meanwhile, the assembly and installation work of the clutch outer hub 11 and the sleeve 12 can be facilitated.
In some embodiments, the clutch outer hub 11 further includes a recessed portion 112 that snap fits with the web 13. Through the setting of recess portion 112, can make things convenient for the alignment work when connecting plate 13 and the outer hub 11 of clutch are installed more, make assembly work simple more high-efficient, can also play spacing effect, further guarantee that the relative position of connecting plate 13 and the outer hub 11 of clutch is difficult for taking place to change.
In a further embodiment, the connecting plate 13 includes an annular plate portion 131, the annular plate portion 131 is snap-fitted with the groove portion 112, the annular plate portion 131 is fixedly connected with the groove portion 112, and the annular plate portion 131 and the groove portion 112 may be welded, bolted or other fixed connection methods, as long as the annular plate portion 131 and the groove portion 112 are fixed together. The annular plate part 131 is of a flat annular structure, and the annular plate part 131 is arranged, so that the overall structure of the connecting plate 13 is simpler, and the production and the processing are easier; it should be noted that, the depth of the groove portion 112 is greater than or equal to the thickness of the annular plate portion 131, so that the connection between the annular plate portion 131 and the groove portion 112 is more reliable, and the annular plate portion 131 is not easily separated from the groove portion 112, and at the same time, the outer side of the annular plate portion 131 can be utilized to the maximum extent to provide effective support for the clutch outer hub 11.
In some embodiments, the sides of the first key connecting portion 111 and the second key connecting portion 121 facing the annular plate portion 131 are both planar structures abutting the annular plate portion 131.
