DETAILED DESCRIPTION

[0023] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0024] Combination Figure 1-3As shown, a hybrid vehicle transmission dual clutch assembly comprises two transmission shafts and a rotating rod 1, wherein the two transmission shafts are respectively provided with a plurality of driving gears, the rotating rod 1 is rotatably connected with a plurality of driven gears 2 corresponding to the driving gears, and a clamping plate is provided on the rotating rod 1 on one side of each driven gear 2;

[0025] The clamping plate comprises a main body 3, a push ring and a movable plate 4;

[0026] The main body 3 is fixed on the rotating rod 1, and the front end of the main body 3 has a guide plate 5, and the outer periphery of the guide plate 5 is arrayed with multiple convex strips 6. The middle part of the movable plate 4 has a through hole corresponding to the guide plate 5 and the convex strips 6. The movable plate 4 is sleeved on the guide plate 5. A plurality of springs 7 are connected between the rear end of the movable plate 4 and the front end of the main body 3, and each of the springs 7 keeps the movable plate 4 in a trend of moving closer to the main body 3.

[0027] The front end of the movable plate 4 is fixed with a first friction plate 8, the rear end of the driven gear 2 is fixed with a second friction plate 9, the front end of the movable plate 4 is also provided with a guide ring 10, the rear end of the driven gear 2 is also provided with a circle of guide grooves 11 corresponding to the guide ring 10, and the front end of the guide ring 10 is inserted into the guide groove 11;

[0028] The push ring is composed of a first ring body 12 and a second ring body 13. The first ring body 12 is connected to the speed control lever and is sleeved on the main body 3. The inner periphery of the first ring body 12 and the outer wall of the main body 3 maintain a distance. The second ring body 13 is rotatably connected to the front end of the first ring body 12.

[0029] The working principle and beneficial effects of the above structure are as follows: initially, the movable plate 4 is arranged close to the main body 3 and is in a separated state from the driven gear 2 under the action of the spring 7, and the transmission shaft drives the driving gear to rotate. Since the driven gear 2 is rotationally connected with the rotating rod 1, the rotating rod 1 does not rotate when the driving gear drives the driven gear 2 to rotate; when the speed is adjusted, the operating lever pushes the first ring body 12 and then the second ring body 13 pushes the movable plate 4, so that the first friction plate 8 of the movable plate 4 fits with the rear end of the second friction plate 9 of the driven gear 2, and the driven gear 2 drives the movable plate 4 to rotate. Since the movable plate 4 is sleeved on the guide plate 5 and meshes with the guide plate 5 through the convex strip 6, the main body 3 and the rotating rod 1 is fixed, the movable plate 4 drives the guide plate 5 to rotate and then drives the main body 3 and the rotating rod 1 to rotate, thereby realizing speed regulation; in the speed regulation process, since the second ring body 13 is rotatably connected to the front end of the first ring body 12, the first ring body 12 does not rotate when the second ring body 13 rotates with the movable plate 4, so as to avoid severe friction between the push ring and the movable plate 4; the guide ring 10 arranged at the front end of the movable plate 4 makes the front and rear displacement of the movable plate 4 more stable and reliable, so as to avoid the spring 7 between the movable plate 4 and the main body 3 from loosening and failing due to factors such as vibration; and the movable plate 4 and the driven gear 2 are driven by the friction plate phase, so that it can be engaged and separated faster, thereby making the clutch react more quickly.

[0030] In another embodiment, if Figure 1 As shown, the inner wall of the guide plate 5 and the outer wall of the rotating rod 1 are in contact with each other to ensure the reliability of the guide plate 5 and prevent it from being broken or bent.

[0031] In another embodiment, if Figure 1 As shown, the guide ring 10 and the inner wall of the guide groove 11 maintain a distance to avoid contact and transmission between the movable plate 4 and the driven gear 2 when they are in a separated state.

[0032] In another embodiment, in combination Figure 1 and Figure 2 As shown, the cross section of the guide ring 10 is trapezoidal to ensure that a sufficient distance is maintained between the guide ring 10 and the guide groove 11 in the separated state.

[0033] In another embodiment, if Figure 1 As shown, a limiting ring 14 for limiting the push ring is also provided at the rear end of the main body 3.

[0034] In another embodiment, if Figure 1 As shown, a bearing 15 is fixed to the front end of the first ring body 12 , and the second ring body 13 is fixed on the bearing 15 . The outer diameter of the second ring body 13 is greater than the outer diameter of the first ring body 12 .

[0035] Specifically, the bearing 15 is a thrust bearing.

[0036] In another embodiment, in combination Figure 1 and Figure 3 As shown, the driven gear 2 also has a avoidance groove 16 corresponding to the guide plate 5, so that the guide plate 5 has a sufficient length so that the first friction plate 8 of the movable plate 4 can fit more reliably with the second friction plate 9 of the driven gear 2.

[0037] In another embodiment, in combination Figure 2 and Figure 3 As shown, the first friction plate 8 and the second friction plate 9 are both annular friction plates.

[0038] In another embodiment, if Figure 1 As shown, the rear end of the main body 3 also has a connecting portion 17, and the connecting portion 17 is fixed to the rotating rod 1 by fixing bolts.
