Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Embodiment
As shown in Figure 1; The clutch of band brake function according to the invention comprises that the clutch that is installed on the live axle initiatively overlaps 1, is installed in the clutch housing on the driven shaft; Clutch initiatively overlaps principal and subordinate's Moving plate 3 is installed on 1; Secondary driven disc 4 is installed on the clutch housing, and principal and subordinate's Moving plate 3 and secondary driven disc 4 Spielpassung are through principal and subordinate's Moving plate 3 and the branch of secondary driven disc 4, the transmission of closing realization power.A plurality of principal and subordinate's Moving plates 3 are installed in clutch with the mode that can cannot not move axially rotatablely and initiatively overlap on 1; A plurality of secondary driven discs 4 are installed on the clutch housing with the mode that can cannot not move axially rotatablely; Principal and subordinate's Moving plate 3 is provided with secondary driven disc 4 at interval, is provided with rubber cushion 5 between principal and subordinate's Moving plate 3 and the secondary driven disc 4.Under the situation of no external force, rubber cushion 5 was opened principal and subordinate's Moving plate 3 and secondary driven disc in 4 minutes, and it is kept at a certain distance away; In the time of outer force urges; Rubber cushion 5 compressive deformations, principal and subordinate's Moving plate 3 fits together with secondary driven disc 4, realizes interlock; Torsion initiatively overlaps 1 from clutch and is delivered to principal and subordinate's Moving plate 3, arrives secondary driven disc 4, clutch housing again.
Said clutch housing comprises inner sleeve 71 and the overcoat 72 that is connected to one; The front end of inner sleeve 71 is inserted into clutch and initiatively overlaps 1 rear end; Be provided with rolling bearing 2 between inner sleeve 71 and clutch initiatively overlap 1, main spring 22 and piston 19 are installed between inner sleeve 71 and overcoat 72, said main spring 22 and piston 19 equal coaxial packages are on inner sleeve 71; The front end of main spring 22 is connected on the inner sleeve 71 through back-up ring; The front end of main spring 22 is resisted against on the piston 19, in clutch housing, is provided with hydraulic oil channel 73, and the inner of said hydraulic oil channel 73 is communicated between inner sleeve 71 and the overcoat 72, the rear end of piston 19; The outer end of hydraulic oil channel 73 is connected with hydraulic pressure installation through pipeline, can promote piston 19 through hydraulic oil channel 73 input hydraulic pressure oil and move forward; Outer surface at clutch housing is provided with annular boss, and annular boss upper edge circumference is a plurality of spring seats of distribution evenly, and auxiliary spring 8 is installed in the spring seat, and auxiliary spring 8 can be two, three, four or more.The outer surface of clutch housing is set with can axially movable brake disc 16; Auxiliary spring 8 is between spring seat and brake disc 16; Said brake disc 16 is fixedly connected with piston 19 through wrist pin 18; Wrist pin 18 passes clutch housing, and front end is fixedly connected on the piston 19, and the rear end is connected on the brake disc 16 through bolt.Evenly upright in order to receive, the quantity of wrist pin 18 is corresponding with the quantity of auxiliary spring 8, equally also is evenly to distribute along circumference.Be installed with baffle plate assembly 15 on the clutch housing, the rear end installed thrust bearing 18 of baffle plate assembly 15 can rotate it.Said baffle plate assembly 15 can be any rule or irregular shape; The block that wherein has a convexity at least cooperates with the object of external stability, in the time of baffle plate assembly 15 rotations; Receive the stopping of object of external stability, it can not be got final product in 360 degree rotations.
During work, under the clutch separation state, main spring 22 promotes piston 19, auxiliary spring 8 promotes brake disc 16 and moves backward, and principal and subordinate's Moving plate 3 separates with secondary driven disc 4, and clutch initiatively overlaps 1 idle running.Even this moment is because the adhesion effect of clutch oil; Secondary driven disc 4 can drive the clutch housings rotation, but brake disc 16 is with after baffle plate assembly 15 combines, and receives the stopping of object of external stability; Clutch housing will soon stop the rotation, and reaches the purpose of braking.
When clutch combines; Promote piston 19 through hydraulic oil channel 73 input hydraulic pressures oil and move forward, main spring 22 is compressed with auxiliary spring 8, and brake disc 16 separates with baffle plate assembly 15; Principal and subordinate's Moving plate 3 combines with secondary driven disc 4 simultaneously; Realize interlock, torsion initiatively overlaps 1 from clutch and is delivered to principal and subordinate's Moving plate 3, arrives secondary driven disc 4, clutch housing again.
