Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a damper-integrated starting device used for a vehicle.

[0002]

2. Description of the Related Art Conventional dampers are those integrated with a torque converter with a lockup clutch, those integrated with a dry clutch, and large-scale vibration dampers of Japanese Patent Publication No. 2-57743 (Japanese Patent Application No. 11-13568). An assembly and the like are known.

In the large process vibration damper in the continuously variable transmission shown in Japanese Patent Publication No. 2-57743, the input member of the damper is attached to the flywheel of the engine, and the hub of the output member of the damper is the input of the continuously variable transmission. It is splined to the shaft and transmits torque while damping engine vibrations and transient torsional vibrations.

Further, the large process damper is used as an input device to a continuously variable transmission, and its torque transmission path is from an engine or a flywheel of the engine to a peripheral flange, which is an input member of a large process vibration damper, and a large process. The damper mechanism body, the output member of the large process vibration damper, the input shaft of the continuously variable transmission, the continuously variable device, the starting clutch, and the forward / reverse switching gear are transmitted in this order.

That is, there is no damper integrated with the wet start clutch in the continuously variable transmission located immediately after the engine except for the torque converter with lockup clutch. It goes without saying that the same applies not only to the continuously variable transmission but also to the automatic transmission.

When the lockup clutch is completely released, the torque transmission path of the damper connected to and integrated with the torque converter with the lockup clutch is such that the engine, the pump impeller of the torque converter, the turbine of the torque converter, the automatic When torque is transmitted in order of the input shaft of the transmission and the main body of the automatic transmission, and when the lockup clutch is engaged or slips, the engine,
Transmission is made in the order of the cover of the pump impeller integrated with the pump impeller of the torque converter, the lockup clutch, the damper, the input shaft of the automatic transmission, and the main body of the automatic transmission. That is, the torque is transmitted regardless of the operation of the lockup clutch, and there is no neutral state in which the transmitted torque is completely cut off. Of course, it goes without saying that even if the friction surface of the lockup clutch is multifaceted, it is the same.

[0007]

As described above,
It is common to place a damper immediately after the engine or the flywheel of the engine, but it transmits the torque integrated with the starting clutch that can transmit torque and attenuates engine vibration and transient torsional vibration. There has not been a damper-integrated starter including a damper device.

[0008]

To achieve the above object, a damper for a starting clutch of the present invention includes a working oil passage for actuating a clutch piston for connecting and disconnecting a starting clutch for a transmission and a friction plate. Characteristically, cooling oil passages for cooling the friction surface are directly connected and integrated with independent start clutches to transmit torque and to damp engine vibrations and transient torsional vibrations. .

[0009] Further, the damper-integrated starting device according to the present invention includes:
An input shaft having a center hole extending in the axial direction and transmitting power to the transmission main body, a shaft member arranged radially outside of the input shaft, and a radial outside of the shaft member. A starting clutch for a transmission, which includes a clutch case that accommodates a clutch portion and a clutch piston that are respectively slidable in an axial direction, and a housing that accommodates the clutch case, and a torque input member for a transmission. A damper device for transmitting torque between the torque output member and the torque output member, and for damping engine vibration, transient torsional vibration, and the like, the damper device comprising:
It is characterized in that it is integrally provided in the housing of the starting clutch.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, a compact design is made possible by integrating a starting clutch and a damper device, and a damper having viscosity is used together with a spring arranged in the radial direction of the starting clutch.

Thus, the damper device can be incorporated into the housing of the starting clutch and directly connected to the starting clutch, so that a compact structure using the housing of the starting clutch can be realized. In addition, the lubricating oil of the main body of the automatic transmission and the starting clutch is used as it is, and the damper device utilizes the viscosity of the lubricating oil and is used in combination with a spring or the like arranged in the radial direction of the starting clutch to prevent vibration of the engine. We have established a damper-integrated starter that damps transient torsional vibrations.

1 is a partially cutaway front view of a damper-integrated starting device according to a first embodiment of the present invention, and FIG. 2 is an axial sectional view of FIG.

The damper-integrated starting device 100 includes a housing 4 that substantially surrounds the entire device. A clutch case 6 is provided in the housing 4 via a spline or the like. A part of the housing 4 is a sleeve 1, a fixed shaft 2 is arranged inside the sleeve 1, and an input shaft 3 is arranged inside the fixed shaft 2. A damper device 5 is further mounted in the housing 4, and the clutch case 6 is connected to the damper device 5 via a spline or the like. The damper device 5 cooperates with the clutch case 6 and the housing 4 to transmit torque.

The damper device 5 shown in FIG.
In order to define a predetermined annular space inside the housing 4, it is provided in a convex portion 7 protruding outward in the radial direction of the housing 4, and a hub plate 10 is provided via a slider 8 and a spring 9 shown in FIG. There is. The hub plate 10 is
The clutch case 6 is connected to the clutch case 6 via a spline or the like on the outer side in the radial direction of the clutch case 6. Hub plate 1
A slider 8 and a spring 9 are arranged between 0 and the convex portion 7 of the housing 4 so as to be slidable in the circumferential direction. It goes without saying that the number of sliders 8 and springs 9 can be set arbitrarily.

A clutch piston 11 is arranged in the clutch case 6 so as to be slidable in the axial direction. A plurality of plates 12 and friction plates 13 which are slidable in the axial direction via splines or the like are provided on the inner side of the clutch case 6 in the radial direction. The fixed plate 1 is provided outside the plate 12.
4 is fixed to the clutch case 6. Three protrusions 15 are provided on the axial rear surface of the convex portion 7 of the housing. The protrusion 15 engages with a drive plate (not shown) of an engine (not shown). In this embodiment, three protrusions 15 are provided, but it goes without saying that the number can be set as needed.

The inner peripheral cylindrical portion 16 of the clutch case 6 is connected to the fixed shaft 2 via a bearing. The inner peripheral cylindrical portion 16 is provided with an annular flange 17 extending outward in the radial direction, and a spring 18 is arranged between the flange 17 and the clutch piston 11. Spring 1
8 gives a force in the direction of pressing the clutch piston 11 against the inner peripheral surface of the clutch case 6. The axially outer end 35 of the clutch piston 11 is the outermost plate 1
2 is in contact with the plate 12 when the starting clutch is engaged.
The other plate 12 and the friction plate 13 are sandwiched between and the fixed plate 14.

The end portion of the input shaft 3 is a disc-shaped hub 19, and a cylindrical portion 20 is provided on the outer side in the radial direction. A plurality of friction plates 13 are provided on the cylindrical portion 20 of the hub 19 so as to be slidable in the axial direction via splines or the like. In this embodiment, one friction plate 13 is sandwiched between the plates 12. That is, two friction plates 13 are provided. However, it goes without saying that the numbers of the plates 12 and the friction plates 13 can be set arbitrarily. Further, the friction material adhered to the friction plate 13 can be provided on both sides and one side. The same applies to the examples described later.

Now, the flow of the friction surface cooling oil of the damper-integrated starter 100 will be described.

A center hole 21 extending in the axial direction of the input shaft 3.
The cooling oil entering from the inside flows through the through hole 22 in the radial direction of the input shaft 3 to the outer peripheral side thereof, and the hub 1 provided at the end thereof.
9. Radial through hole 23 of cylindrical portion 20 radially outside 9
Via the friction plate 13 and the friction surface of the plate 12 and a through groove provided in the friction surface to cool the friction surface, and the cylindrical portion 2 on the radially outer side of the clutch case 6 is cooled.
The oil after cooling the friction surface is discharged to the outside of the cylindrical portion of the clutch case 4 through the through hole 25 provided in the clutch 4. The discharged oil flows between the hub plate 10 of the damper device 5 and the inside of the housing 4 and flows into the space between the sliders 8 in which the springs are arranged. On the other hand, clutch case 6
The oil discharged to the outside of the cylindrical portion 24 is drained through the oil passage 26 into the gap 27 formed between the inner peripheral side of the sleeve 1 of the housing and the outer peripheral side of the fixed shaft. If the damper device 5 is already filled with oil, the cylindrical portion 2 of the clutch case 6
The oil discharged to the outside of 4 is always drained through the oil passage 26 into the gap 27 formed between the inner peripheral side of the sleeve 1 of the housing 4 and the outer peripheral side of the fixed shaft 2.

Next, the flow of the starting clutch hydraulic oil of the damper-integrated starting device 100 will be described.

First, the hydraulic oil, which has entered through the gap 28 formed between the outer peripheral side of the input shaft 3 and the inner peripheral side of the fixed shaft 2, passes through the through hole 29 on the outer side of the fixed shaft 2 in the radial direction, and enters the clutch case 6. It goes to the hydraulic chamber 31 via a hole 30 provided in the circumferential side cylindrical portion 16. When engaging the start clutch, the hydraulic pressure in the hydraulic chamber 31 is increased, and the clutch piston 11 is moved leftward in FIG. 1 by the hydraulic pressure. As a result,
The friction plate 13 and the plate 12 are fastened to each other between the clutch piston 11 and the fixed plate 14, and the starting clutch is brought into a fastened state to enable power transmission. If the hydraulic pressure in the hydraulic chamber 31 is reduced, the clutch piston 11
Is moved to the right in FIG. 1 by the reaction force of the spring 18, and the friction plate 13 and the plate 12 are separated from each other,
The starting clutch engagement state is released and the engagement state is changed to the non-engagement state. By arbitrarily adjusting the pressure in the hydraulic chamber 31 in this manner, the power transmission rate of the starting clutch can be freely controlled from approximately 0 to 100%.

The damper-integrated starter 100 described above
Since the friction surface cooling oil passage and the starting clutch operating oil passage are independent of each other, the operation of the starting clutch and the cooling of the friction surface can be independently controlled. Further, even if the starting clutch and the damper device are integrated, there is no influence on the starting clutch itself.

Here, the power transmission path will be described.

First, when the starting clutch is engaged, it is transmitted from an engine (not shown) through a drive plate (not shown) to the housing 4 which is integrated with the projection 15 provided on the rear surface of the housing 4. Next, power is applied to the housing 4
Is transmitted from the convex portion 7 through the spring 9 and the slider 8, that is, the damper device 5 to the clutch case connected to the outer peripheral side of the clutch case cylindrical portion 24 by a spline or the like. Further, a friction plate 13 in which a plate 12 connected to the inner peripheral side of the cylindrical portion 24 of the clutch case 6 via a spline or the like is pressed by the clutch piston 11.
It is transmitted to the input shaft 3 via the hub 19.

Next, when the starting clutch is disengaged, the power output from the engine (not shown) is passed through the drive plate (not shown) and the projection 1 provided on the rear surface of the housing 4 is used.
5 is transmitted to a housing 4 which is integral with the housing 5. Next, the power is transmitted from the convex portion 7 of the housing 4 via the spring 9 and the slider 8 to the clutch case 6 connected to the outer peripheral side of the cylindrical portion 24 of the clutch case 6 by a spline or the like. Further, it is transmitted to the plate 12 connected to the outer peripheral side of the cylindrical portion 24 of the clutch case 6 via a spline or the like. However, when the starting clutch is disengaged, the connection between the plate 12 and the friction plate 13 is cut off, so there is no power transmission from the plate 12 to the friction plate 13 and the starting clutch is in the neutral state.

Further, the damper-integrated starter 100 can be applied not only to the conventional automatic transmission (A / T) but also to other power transmission mechanisms such as a continuously variable transmission such as a CVT. Is possible.

According to the first embodiment described above, the damper device 5 damps engine vibrations and transient torsional vibrations, so that the damper-integrated starter device 100 used as a part of the power transmission device is provided. It is possible to improve the riding comfort of the vehicle and improve the driving operability of the vehicle. Further, it goes without saying that the durability and the life of the starting clutch itself are improved.

Torsional vibration and the like are attenuated by utilizing the viscosity and the labyrinth structure of the oil discharged from the holes 46 which are arranged at a constant interval and penetrate radially outward of the clutch case 42. However, it goes without saying that the number of the flanges 41 and 44 can be set arbitrarily.

And a flange 68. The three pairs of annular flanges 68 are interposed in the gap between the annular flanges 61 and the gap between the annular flanges 62.
Torsional vibration or the like is damped by utilizing the viscosity of the oil discharged from the hole 66 penetrating radially outward of the clutch case 65 and the labyrinth structure.

In the damper devices of the second and third embodiments, the radial length of the flange or the circumferential length of the annular flange are substantially the same, but they are arbitrary within the range in which the required damper performance is obtained.
