Degree.By the way that the end face of platen tooth is arranged to the sharp face that two pitch faces form, come it is larger improve clutch compressing disc to from
The brake force of clutch piece.
Preferably, the central angle of the platen tooth is 20 degree, the central angle of the U-lag is 40 degree, the adjacent U-shaped
Part between slot corresponds to two platen teeth.
Preferably, depth of the U-lag apart from interior disk is 1/3rd of platen body thickness；The annular groove
Depth apart from interior disk is a quarter of platen body thickness.The specific setting of depth, can either ensure the timely of heat
It scatters and disappears, and does not interfere with the intensity of platen body.
Preferably, the lateral cross section of the lug is the shape of isosceles trapezoid, the lug is equipped with mounting hole, described
The one side of lug is equipped with reinforcing rib with the junction of platen body.Lateral cross section causes the fixed installation of platen for trapezoidal lug
More securely；The setting of reinforcing rib increases the bonding strength between lug and platen body, so that the intensity of entire platen
Performance is also more preferable.
The utility model has the advantages that：
(1) by setting the platen that several longitudinal cross-sections for protruding from outer disk are sharp face in the first-class central angle of outer disk
Tooth avoids platen existing slippage problems when being in contact braking with clutch disc, ensure that the effect of engine power output
Rate；
(2) by setting the thermal vias, annular groove and the U-lag that are reasonably distributed, to enable the intrinsic heat of platen
It is enough to scatter and disappear in time, platen body is avoided because internal heat is excessively high, and existing mutability, the problem of short life；
(3) by the way that lug is arranged to section for trapezoidal shape so that the fixed installation of platen is more secured；By
The one side of lug sets reinforcing rib with the junction of platen body, increases the bonding strength between lug and platen body.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the Section A-A figure in Fig. 1；
Fig. 3 is enlarged drawing at B in Fig. 2.
Mark in attached drawing for：1- platen bodies, 2- centre bores, 3- lugs, the outer disks of 4-, disk in 5-, 6- platen teeth,
