Description

Transmission device
Technical Field
The invention relates to the technical field of transmission. More particularly, the present invention relates to transmissions for motor vehicles.
Background
In the prior art, a dual mass flywheel is generally installed between an engine crankshaft of a vehicle and an input shaft of a transmission, and is used for transmitting torque of the engine crankshaft to the input shaft of the transmission under the condition of effectively attenuating torsional vibration of the engine crankshaft, so that the influence of the torsional vibration of the engine crankshaft on the transmission is reduced. Due to the high damping requirements of automatic transmissions, dual mass flywheels as dampers typically use large arcuate springs to damp torsional vibrations. In addition, in hybrid vehicles, torque limiters may also be provided to protect the powertrain from torque overload. However, systems having both a damper and a torque limiter are generally complex, have a high number of parts, and are costly.
Therefore, a transmission device having both vibration damping and torque limiting effects is required, which can reduce the number of components or cost.
Disclosure of Invention
It is an object of the present invention to provide a transmission device with vibration damping and torque limiting effects that can reduce the number of components. Another object of the present invention is to provide a transmission device comprising a centrifugal pendulum damper and a torque limiter with a simplified structure.
One aspect of the present invention provides a transmission comprising: a flange; a side plate provided to be rotatable in a circumferential direction within a predetermined range with respect to the flange; a damping spring disposed in a spring mounting portion formed by the flange and the side plate for damping torsional vibration; a centrifugal pendulum support torsionally connected to one of the flange and the side plate; a torque limiter outer hub comprising a radially outer surface and a radially inner surface, wherein the torque limiter outer hub is torsionally connected to the one of the flange and the side plate by the radially outer surface; a first friction member and a second friction member provided radially inside the torque limiter outer hub and frictionally engaged with each other for transmitting torque within a limit torque range, the first friction member being torsionally connected with a radially inner surface of the torque limiter outer hub; and an output hub having an axis of rotation, wherein the flange, the side plate, the centrifugal pendulum support, the torque limiter outer hub, the first friction element, the second friction element and the output hub are arranged coaxially with respect to the axis of rotation, the second friction element being connected in a rotationally fixed manner to the output hub.
According to an embodiment of the present invention, the flange includes a first flange plate and a second flange plate, wherein the first flange plate and the second flange plate are provided to be rotatable relative to each other in a circumferential direction within a predetermined range.
According to an embodiment of the invention, the side plates comprise a first side plate and a second side plate which are connected to each other in a rotationally fixed manner, the first flange plate and the second flange plate being arranged axially between the first side plate and the second side plate, wherein the first side plate, the first flange plate, the second flange plate and the second side plate are arranged axially in succession.
According to an exemplary embodiment of the present invention, the centrifugal pendulum support and the torque limiter outer hub are connected to the second flange in a rotationally fixed manner.
According to an embodiment of the invention, the centrifugal pendulum support and the torque limiter outer hub are integrally formed.
According to an embodiment of the invention, the transmission device further comprises a connecting member, wherein the second side plate comprises an arc-shaped through hole, and the connecting member penetrates through the arc-shaped through hole of the second side plate to fixedly connect the centrifugal pendulum support to the second flange plate.
According to an embodiment of the invention, the centrifugal pendulum support and the torque limiter outer hub are formed separately and the centrifugal pendulum support is fixedly connected to the torque limiter outer hub.

Another aspect of the invention provides a vehicle comprising a transmission according to an embodiment of the invention.
According to the embodiment of the invention, the transmission device has the functions of vibration reduction and moment limitation, and simultaneously can realize a centrifugal pendulum type vibration reduction structure through the centrifugal pendulum bracket. The centrifugal pendulum carrier and the torque limiter outer hub of the transmission are connected in a rotationally fixed manner to one of the flange and the side plate, for example the second flange plate. The transmission of the present invention allows for a reduction in the number of parts and cost relative to, for example, configurations employing dual mass flywheels. Preferably, the centrifugal pendulum support is formed integrally with the torque limiter outer hub. This can simplify the manufacturing and assembly process of the transmission and reduce the cost.

Detailed Description
Hereinafter, embodiments of the present invention are described with reference to the drawings. The following detailed description and drawings are illustrative of the principles of the invention, which is not limited to the preferred embodiments described, but is defined by the claims. The invention will now be described in detail with reference to exemplary embodiments thereof, some of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings, in which like reference numerals refer to the same or similar elements in different drawings unless otherwise indicated. The aspects described in the following exemplary embodiments do not represent all aspects of the present invention. Rather, these aspects are merely exemplary of the systems and methods according to the various aspects of the present invention as recited in the appended claims.
The invention provides a transmission device for a motor vehicle. Hereinafter, exemplary embodiments of the present invention are described with reference to the accompanying drawings. It is to be understood that only certain embodiments of the invention have been shown in the drawings and that the scope of the invention should be determined from the following claims.
FIG. 1 is a side cross-sectional view of a transmission according to certain embodiments of the present invention. According to some embodiments of the present invention, as shown in fig. 1, the transmission includes a first side plate 10, a second side plate 20, a first flange 30, a second flange 40, a damper spring 50, a centrifugal pendulum support 60, a torque limiter outer hub 70, a first friction member 80, a second friction member 90, and an output hub 100.
In the exemplary embodiment, the transmission side plates include a first side plate 10 and a second side plate 20. The first side plate 10 and the second side plate 20 are connected together torsionally fixed. In other embodiments, the side panels may take other configurations, such as including only a single side panel.
In the exemplary embodiment, the transmission flanges include a first flange 30 and a second flange 40. The side plate is rotatable relative to the flange in a circumferential direction within a predetermined range. In the exemplary embodiment, first and second flanges 30, 40 are disposed axially between first and second side plates 10, 20. As shown in fig. 1, the first side plate 10, the first flange 30, the second flange 40, and the second side plate 20 are arranged in this order in the axial direction. In an exemplary embodiment, the first flange 30 may serve as an input to the transmission, wherein the first flange 30 is adapted to be torsionally connected to a crankshaft of the engine.
In the exemplary embodiment, the transmission includes a plurality of damper springs 50 for damping torsional vibrations between the flange and the side plates. Each of the damper springs 50 is mounted in a spring mounting portion formed by the first side plate 10, the second side plate 20, the first flange 30, and the second flange 40. In some embodiments, the damper springs 50 include damper springs for transmitting torque through compression between the first flange 30 and the first/ second side plates 10, 20, and damper springs for transmitting torque through compression between the first/ second side plates 10, 20 and the second flange 40.
According to some embodiments of the present invention, the first flange 30 is provided to be rotatable in the circumferential direction within a predetermined range with respect to the first side plate 10/the second side plate 20, the second flange 40 is provided to be rotatable in the circumferential direction within a predetermined range with respect to the first side plate 10/the second side plate 20, and the first flange 30 and the second flange 40 are provided to be rotatable in the circumferential direction within a predetermined range with respect to each other. According to some embodiments of the present invention, the relative rotation angle of the first flange 30 with respect to the second flange 40 is equal to the sum of the relative rotation angle of the first flange 30 with respect to the first side plate 10/second side plate 20 and the relative rotation angle of the first side plate 10/second side plate 20 with respect to the second flange 40. In some embodiments, the first side plate 10, the second side plate 20, the first flange 30, and the second flange 40 have different types of spring mounting holes. The first flange 30 and the second flange 40 can achieve series torque transmission by cooperation between different damping springs and different spring mounting holes. For example, when the first flange 30 receives torque from the crankshaft of the engine, the torque may be transmitted along the following path: first flange 30 → damper spring → first side plate 10/second side plate 20 → damper spring → second flange 40. This increases the angle of torsion, which reduces the torsional stiffness of the transmission and improves the damping effect.
According to an embodiment of the invention, the centrifugal pendulum support 60 and the torque limiter outer hub 70 are connected to the same one of the flange and the side plate, respectively, in a torsion-proof manner. In the exemplary embodiment, the centrifugal force pendulum support 60 is connected to the second flange 40 in a rotationally fixed manner. The centrifugal pendulum support 60 serves to support the pendulum mass 61 in such a way that the pendulum mass 61 can pivot relative to the centrifugal pendulum support 60 during the transmission of torque from the transmission. The oscillating movement of the oscillating mass element can further reduce the torsional oscillation of the transmission device.
In some embodiments, as shown in FIG. 1, the centrifugal pendulum support 60 is integrally formed with the torque limiter outer hub 70. For example, the centrifugal pendulum support 60 and the torque limiter outer hub 70 may be integrally formed by a stamping process or the like. In the exemplary embodiment, torque limiter outer hub 70 includes a radially outer surface 71 and a radially inner surface 72. The torque limiter outer hub 70 includes external splines on a radially outer surface 71 and internal splines on a radially inner surface 72. The centrifugal pendulum support 60 and the torque limiter outer hub 70 can be connected in a rotationally fixed manner to the second flange 40 by means of external splines.
The first and second friction members 80, 90 serve to limit the maximum torque that can be transmitted from the input to the output of the transmission. According to an embodiment of the present invention, the first friction member 80 and the second friction member 90 are frictionally engaged with each other for transmitting torque within a limit torque range. In the limit torque range, the first and second friction members 80 and 90 rotate together by a frictional force therebetween. Relative slippage between the first friction member 80 and the second friction member 90 will occur when the limit torque range is exceeded. In an exemplary embodiment, the first and second friction members 80 and 90 include a plurality of friction disks, respectively, with the friction disks of the first friction member 80 and the friction disks of the second friction member 90 being spaced apart and clamped to each other.
In the exemplary embodiment, first friction member 80 and second friction member 90 are disposed radially inward of torque limiter outer hub 70. The first friction element 80 is connected in a rotationally fixed manner, for example by internal splines or teeth, to the radially inner surface 72 of the torque limiter outer hub 70. The second friction element 90 is connected to the output hub 100 in a rotationally fixed manner. In the exemplary embodiment, the first side plate 10, the second side plate 20, the first flange 30, the second flange 40, the centrifugal pendulum support 60, the torque limiter outer hub 70, the first friction member 80, the second friction member 90, and the output hub 100 are arranged coaxially with the rotation axis (the rotation axis of the output hub 100). In an exemplary embodiment, the output hub 100 may serve as the output of a transmission, wherein the output hub 100 is adapted to be torsionally connected to an input shaft of a gearbox.
According to some embodiments of the present invention, the torque limiter outer hub 70 axially restrains the first friction member 80 and the second friction member 90 by the integrally formed protrusion 73 at one axial end and the stopper 74 provided at the other axial end. The projection 73 and the stopper 74 are provided on the radially inner surface of the torque limiter outer hub 70. In some embodiments, the projections 73 may be formed by bending the torque limiter outer hub 70. In some embodiments, the stop 74 is formed separately from the torque limiter outer hub 70 and is mounted to a radially inner surface (e.g., a corresponding groove) of the torque limiter outer hub 70; or the stop 74 may be formed integrally with the torque limiter outer hub 70. In some embodiments, a spring 75 (e.g., a diaphragm spring) may also be provided between the first/ second friction members 80, 90 and the stop 74 to maintain compression between the first and second friction members 80, 90 by the axial force exerted by the spring 75. In some embodiments, a support plate 76 may also be provided between the first friction member 80/the second friction member 90 and the projection 73 to better constrain the first friction member 80 and the second friction member 90 in the axial direction.
The centrifugal pendulum support 60 and torque limiter outer hub 70 are described above as being integrally formed. However, the present invention is not limited thereto. According to an embodiment of the invention, the centrifugal pendulum support 60 and the torque limiter outer hub 70 may also be formed separately.
FIG. 2 is a side cross-sectional view of a transmission according to certain embodiments of the present invention. As shown in fig. 2, the centrifugal pendulum support 60 is formed separately from the torque limiter outer hub 70, and the centrifugal pendulum support 60 can be connected to the second flange 40 by, for example, a connecting element 110. The second side plate 20 forms an arc-shaped through hole 21. The connection member 110 passes through the arc-shaped through hole 21. Thus, when the centrifugal pendulum support 60 rotates with the second flange 40 relative to the second side plate 20, the connecting element 110 can move along the curved through hole 21 to avoid affecting the relative rotation.
FIG. 3 is a side cross-sectional view of a transmission according to certain embodiments of the present invention. As shown in fig. 3, the centrifugal pendulum support 60 is formed separately from the torque limiter outer hub 70, and the centrifugal pendulum support 60 is fixedly connected to the torque limiter outer hub 70. In the exemplary embodiment, centrifugal pendulum support 60 is fixedly coupled to a portion of torque limiter outer hub 70 that is axially outward of a side plate (e.g., second side plate 20).
The torque limiter outer hub 70 is described above as being splined to torsionally secure the second flange 40 to the first friction member 80. However, the present invention is not limited thereto. According to some embodiments of the invention, the torque limiter outer hub 70 and the centrifugal pendulum support 60 may also be connected to the above components in other ways, such as riveting, interference connection, welding, etc., in a torsionally stiff manner.
The torque limiter outer hub 70 described above restrains the first friction member 80 and the second friction member 90 by the projection 73 and the stopper 74 at the axial both ends, respectively. However, the present invention is not limited thereto. According to some embodiments of the invention, the transmission may also constrain the first friction member 80 and the second friction member 90 in other ways, such as two protrusions or two stops at both axial ends of the torque limiter outer hub 70. Alternatively, two axial stop elements can be provided on the output hub 100, or one on the output hub 100 and the other on the torque limiter outer hub 70.
The transmission described above includes two flanges. However, the present invention is not limited thereto. According to some embodiments of the invention, the transmission may also comprise only a single flange. In this case, the centrifugal pendulum support 60 and the torque limiter outer hub 70 can be connected to the side plates or flanges in a rotationally fixed manner. For example, when the single flange plate serves as the input of the transmission, the centrifugal pendulum support 60 and the torque limiter outer hub 70 may be connected to the side plates in a rotationally fixed manner (e.g., via splines, etc.).
While the invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the construction and methods of the embodiments described above. On the contrary, the invention is intended to cover various modifications and equivalent arrangements. In addition, while the various elements and method steps of the disclosed invention are shown in various example combinations and configurations, other combinations, including more, less or all, of the elements or methods are also within the scope of the invention.
