As preferably, described follower plate is riveted on the described protecgulum inner side surface.
As preferably, described protecgulum comprises flat and a plurality of stiffening rib of the annular at edge, and this stiffening rib is located at flat center and radially direct, is convenient to make on product various signs.
Be communicated with by a connected pore channel between described engagement vestibule and the silicone oil vestibule, the intermediate portion at described active plate and valve block is opened in this connected pore channel, valve opening is then opened on described follower plate near circumferential location, described protecgulum has pin shaft hole, bearing pin is arranged in the pin shaft hole a described temperature-sensitive support and a seal ring to be fixed on the described protecgulum, one end of described valve block is riveted on the described follower plate, described housing with the protecgulum faying surface on have groove, be lined with seal washer in this groove.Compact to design reasonable, assembling is produced easily.
Further, have on the driving shaft by bearing fixing in the middle of the described housing, this bearing then is fixed on the described housing by bearing hole flange in the housing, and this bearing is fixed on described driving shaft on the central position of described housing by cooperating with ladder circle on the driving shaft.
Compared with prior art, advantage of the present utility model is: by changing the material and the production technology of traditional aluminium matter protecgulum, removed the machining time in the conventional procedure, directly adopt steel material die sinking punching press just can, die cost is low; Speed of production is fast; The precision height need not mechanical deep processing, and mould and die accuracy is controlled easily, and repair rate is little; The working environment of workers improves greatly, whole environmental protection and energy saving; Utilize welding and riveting technology fixed support and follower plate to realize the fundamental function of protecgulum; And can install the temperature sensing device of different shape flexibly additional, thereby make product have more performance and longer working life, and effectively reduce production costs, simple in structure, easy assembling production, whole clutch configuration is compact to design, reasonable, is adapted at promoting the use of on the motor car engine.
