Description

Technical Field

[0001] The utility model belongs to the technical field related to automobile vibration reduction, in particular to a damping plate of a wet dual-clutch automatic transmission. Background Art

[0002] The design of the vibration damping plate uses the input shaft to transmit the engine power to the clutch to drive the car through the spring and the plastic aluminum alloy slider. The spring acts to reduce vibration and isolate the vibration of the engine so that it can flexibly transmit power to the dual clutch and shift mechanism. The plastic aluminum alloy slider plays a supporting role between the springs, but it still has the following disadvantages in actual use:

[0003] When the plastic aluminum alloy slider on the damping plate is damaged, the springs lose their supporting function, resulting in too large a gap, causing the input shaft to impact the spring, produce abnormal noise, and jerk the car. In severe cases, the power cannot be transmitted and the car cannot be driven.

[0004] When working on the damping disc, two mounting ears are used for installation between the input disc and the driven disc of the damping disc. When the mounting ears are subjected to the impact of the damping spring for a long time, because there are only two force points, the mounting ears are easily broken, causing the vehicle to be obstructed.

[0008] Furthermore, stoppers are symmetrically fixed to the inner bottom of the outer shaft housing, and two of the stoppers are respectively arranged under the two mounting plates. The outer shaft housing is driven to rotate by the stoppers under the push of the damping spring.

[0009] Furthermore, a movable bearing is fixed vertically through the center of the support plate, the movable bearing is sleeved in a movable sleeve, and an inner plate is fixed around the movable bearing between the movable sleeve and the support plate, and the support plate is movably supported in the movable sleeve through the movable bearing.

[0010] Furthermore, a balancing ring is fixed at the edge of the bottom end surface of the support plate, and rotating holes are vertically opened in a circular array in the support plate between the balancing ring and the inner plate, and the support plate is internally supported by the balancing ring.

[0011] Furthermore, the outer mounting frame also includes mounting holes, reinforcement strips and fixing strips. Reinforcement strips are fixed at both ends of the reinforcement block and the mounting plate. Fixing strips are fixed on the side of the reinforcement block and the mounting plate close to the support plate. The fixing strips are fixed to the peripheral side of the support plate. The two ends of the reinforcement strips are respectively fixed to the fixing strips and the outer ring. A mounting hole is vertically penetrated on the top of each mounting plate. The mounting plate is movably connected to the installed components through the mounting holes on the mounting plate, and the strength against spring impact is increased through the cooperation of the reinforcement strips and the fixing strips.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that the plastic aluminum alloy slider on the damping plate of a wet dual-clutch automatic transmission is easily damaged and affects the safety of use by arranging an outer shaft shell, a support plate, an outer mounting frame and an aluminum alloy slider. When the support plate rotates, the outer mounting frame is driven to rotate. When the outer mounting frame rotates, the damping spring between the reinforcing block and the mounting plate is pushed to move until the damping spring moves to squeeze the stopper in the outer shaft shell, pushing the outer shaft shell to rotate. During the compression of the damping spring, the aluminum alloy slider is driven to slide in the outer shaft shell. When working, the aluminum alloy slider can be well passed, thereby increasing the smoothness of sliding. Replacing with a metal aluminum alloy slider increases the smoothness of use, improves firmness and is safe to use.

[0015] The utility model solves the problem that there are only two force points on the damping plate of a wet dual-clutch automatic transmission, which easily causes the fracture of the mounting ears, by arranging a support plate, an external mounting frame and an aluminum alloy sliding block. When the support plate rotates, the reinforcing strips connected to the reinforcing block and the reinforcing strips connected to the mounting plate push the damping spring, so that when the damping spring rebounds, it impacts the reinforcing strips on the reinforcing block and the mounting plate. During the working process, the two reinforcing blocks and the two mounting plates work to provide multiple contact positions, and when working, it is better to prevent the reinforcing block and the mounting plate from being fractured due to rebounding.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0025] See also Figure 1-6The utility model is a damping plate of a wet dual-clutch automatic transmission, comprising an outer shaft housing 1, a support plate 2, an outer mounting frame 3 and an aluminum alloy slider 4. A movable sleeve 101 is fixed through the bottom center of the outer shaft housing 1. The outer shaft housing 1 stably supports the support plate 2, the outer mounting frame 3 and the aluminum alloy slider 4 therein, and is movably connected to a movable bearing 202 through the movable sleeve 101. A support plate 2 is arranged above the movable sleeve 101. The support plate 2 is used to transmit the power of the transmission shaft on the automobile. The support plate 2 is arranged in the outer shaft housing 1. When the support plate 2 is working, the power is transmitted to the damping spring 401. The outer mounting frame 3 is fixed to the peripheral side of the support plate 2. The aluminum alloy slider 4 and the damping spring 4 are restricted by the outer mounting frame 3. The outer mounting frame 3 includes an outer ring 301, a reinforcement block 302 and a mounting plate 303. The reinforcement blocks 302 are symmetrically fixed inside the outer ring 301. The mounting plates 303 are fixed on the inner wall of the outer ring 301 between the two reinforcement blocks 302. The outer ring 301 connects the reinforcement blocks 302 and the mounting plates 303 thereon, and restricts the aluminum alloy slider 4 and the vibration damping springs 401 at both ends of the aluminum alloy slider 4. An aluminum alloy slider 4 is arranged between the reinforcement block 302 and the mounting plate 303. The aluminum alloy slider 4 is movably connected in the outer shaft shell 1. The aluminum alloy slider 4 is slidably connected in the outer shaft shell 1, so that when working, the power between the outer shaft shell 1 and the support disk 2 is transmitted.

[0026] Specifically, the outer shaft housing 1 has stoppers 102 symmetrically fixed to the inner bottom, and the two stoppers 102 are respectively arranged under the two mounting plates 303. After the damping spring 401 is pressed onto the outer shaft housing 1 through the stoppers 102, transmission can be performed between the outer shaft housing 1 and the support plate 2 when working.

[0027] Furthermore, a movable bearing 202 is fixed vertically through the center of the support plate 2, the movable bearing 202 is sleeved in the movable sleeve 101, and an inner plate 204 is fixed on the circumferential side of the movable bearing 202 between the movable sleeve 101 and the support plate 2. The support plate 2 is sleeved in the movable sleeve 101 through the movable bearing 202, and with the support of the inner plate 204, the outer shaft housing 1 and the support plate 2 are well supported and restricted.

[0028] Furthermore, a balancing ring 203 is fixed at the edge of the bottom end surface of the support plate 2, and a rotating hole 201 is vertically opened in a circular array in the support plate 2 between the balancing ring 203 and the inner plate 204. The support plate 2 is coordinated through the balancing ring 203 to provide support when the support plate 2 and the outer shaft shell 1 rotate, thereby cooperating with the support between the outer shaft shell 1 and the support plate 2.

[0029] Furthermore, the outer mounting frame 3 also includes mounting holes 304, reinforcing strips 305 and fixing strips 306. Reinforcing strips 305 are fixed to both ends of the reinforcing block 302 and the mounting plate 303. Fixing strips 306 are fixed to the side of the reinforcing block 302 and the mounting plate 303 close to the support plate 2. The fixing strips 306 are fixed to the peripheral side of the support plate 2. The two ends of the reinforcing strips 305 are respectively fixed to the fixing strips 306 and the outer ring 301. A mounting hole 304 is vertically penetrated at the top of each mounting plate 303. The reinforcing blocks 302 and the mounting plates 303 increase the connection strength with the outer ring 301 through the reinforcing strips 305, and are fixed to the peripheral side of the support plate 2 through the fixing strips 306, so that the support plate 2 is fixed together with the reinforcing blocks 302 and the mounting plates 303.

[0030] The operation process of this embodiment is as follows: when working, first set the support plate 2 into the outer shaft shell 1, then insert the movable bearing 202 under the support plate 2 into the movable sleeve 101 at the bottom of the outer shaft shell 1, and rotate it so that the mounting plate 303 included in the outer mounting frame 3 is rotated to align with the stop block 102, and then put the aluminum alloy slider 4 between the reinforcement block 302 and the mounting plate 303, and then put the shock-absorbing spring 401 between the reinforcement block 302 and the aluminum alloy slider 4, the mounting plate 303 and the aluminum alloy slider 4, and when the support plate 2 rotates, the reinforcement strip 305 connected to the reinforcement block 302 and the reinforcement strip 305 connected to the mounting plate 303 push the shock-absorbing spring 401, so that when the shock-absorbing spring 401 rebounds, it impacts the reinforcement strip 305 on the reinforcement block 302 and the mounting plate 303. During the working process, two reinforcement blocks 302 and two mounting plates 303 work to provide multiple contact positions, and when working, it is better to prevent the reinforcement block 302 and the mounting plate 303 from breaking due to rebounding. Specific embodiment 2

[0031] See also Figure 1 , 2 6. On the basis of the specific embodiment 1, both ends of each aluminum alloy slider 4 are provided with a damping spring 401, and each aluminum alloy slider 4 and the damping springs 401 at both ends thereof are arranged in the outer shaft shell 1 between the reinforcing block 302 and the mounting plate 303. By arranging the complete aluminum alloy slider 4 between two adjacent damping springs 401, when the damping spring 401 bounces, the aluminum alloy slider 4 will not be damaged when the aluminum alloy slider 4 moves in the outer shaft shell 1.

[0032] The operation process of this embodiment is: during operation, when the support plate 2 rotates, the outer mounting frame 3 is driven to rotate. When the outer mounting frame 3 rotates, the damping spring 401 between the reinforcing block 302 and the mounting plate 303 is pushed to move, until the damping spring 401 moves to squeeze the stopper 102 in the outer shaft shell 1, and the outer shaft shell 1 is pushed to rotate. During the compression of the damping spring 401, the aluminum alloy slider 4 is driven to slide in the outer shaft shell 1. When working, the aluminum alloy slider 4 can be passed well to increase the sliding smoothness.
