Description

TECHNICAL FIELD

[0001] The embodiment of the present application relates to the field of mechanical equipment, in particular to a vehicle and a flexible plate thereof. BACKGROUND

[0002] In a hybrid vehicle, due to the structure, a connecting component of a motor assembly and the like is arranged between an engine and a gearbox.

[0003] Please refer to Figure 1 , Figure 1 It is a structural schematic view of the connecting component.

[0004] As shown in the figure, the connecting component comprises a flexible plate 1, an output shaft of an engine and an input shaft of a gearbox are connected with the flexible plate 1, and a housing of the gearbox is connected with a connecting flange 2 of the connecting component.

[0005] The housing of the gearbox is connected with the connecting flange 2 of the connecting component, and the input shaft of the gearbox is connected with a hub 11 of the connecting component, and due to the machining precision and the installation precision and the like, the center positions of the two cannot completely coincide, and therefore, the flexible plate 1 is arranged in the connecting component, so as to compensate the radial eccentricity through the deformation of the flexible plate 1, so as to ensure the smooth installation of the input shaft of the gearbox and the hub 11 of the connecting component.

[0006] It can be seen that after the connection, the flexible plate 1 will bear the radial force, and the flexible plate 1 is supported on the main bearing which has an axial distance from the hub 11 through the hub 11 in the middle, so that the main bearing will bear the additional bending moment generated by the radial force, and the service life of the main bearing is affected.

[0007] Therefore, how to reduce the additional bending moment borne by the main bearing has become a technical problem to be solved by the person skilled in the art. SUMMARY

[0008] The technical problem solved by the embodiment of the present application is to provide a vehicle and a flexible plate thereof, so as to reduce the bending moment borne by the main bearing.

[0009] In order to solve the above problems, the embodiment of the present application provides a flexible plate, comprising:

[0010] A hub comprises a hub body and a hub connecting piece fixed to the outer peripheral part of the hub body;

[0011] A fan-shaped deformation plate group comprises at least one fan-shaped deformation plate which is stacked in sequence, the inner ring surface of the fan-shaped deformation plate is matched with the outer peripheral surface of the hub body, the fan-shaped deformation plate is provided with a radial force deformation hole, the inner ring part of the fan-shaped deformation plate is connected with the hub connecting piece, and the outer ring part of the fan-shaped deformation plate is provided with a fixed connection hole;

[0012] The number of the fan-shaped deformation plate groups is at least two, and the fan-shaped deformation plate groups are arranged in a circular ring shape.

[0021] Optionally,

[0022] The first mounting avoidance hole is in communication with the radial force deformation hole.

[0023] Optionally,

[0024] The number of the fan-shaped deformation plate groups ranges from 3 to 8.

[0025] Optionally,

[0026] In the same fan-shaped deformation plate group, the number of the fan-shaped deformation plates ranges from 1 to 3.

[0027] Optionally,

[0028] The fan-shaped deformation plate includes a fan-shaped plate and a connecting plate arranged in the same plane, the connecting plate is fixed to the outer peripheral part of the fan-shaped plate, the inner ring part of the fan-shaped plate is connected with the hub connector, and the connecting plate is provided with the fixed connection hole.

[0029] To solve the above problems, the embodiment of the present application further provides a vehicle including a gearbox and the flexible plate as described in any one of the above, and the input shaft of the gearbox is connected with the hub of the flexible plate.

[0030] Compared with the prior art, the technical scheme of the embodiment of the present application has the following advantages:

[0031] The vehicle and the flexible plate thereof provided by the embodiment of the present application, wherein the flexible plate comprises: a hub, comprising a hub body and a hub connecting piece fixed to the outer circumferential part of the hub body; and a fan-shaped deformed plate group, comprising at least one fan-shaped deformed plate stacked in sequence, the inner ring surface of the fan-shaped deformed plate being matched with the outer circumferential surface of the hub body, the fan-shaped deformed plate being provided with a radial force deformed hole, the inner ring part of the fan-shaped deformed plate being connected with the hub connecting piece, and the outer ring part of the fan-shaped deformed plate being provided with a fixed connecting hole; and the number of the fan-shaped deformed plate group is at least two, and the fan-shaped deformed plate group is arranged in a circular ring shape. The inner ring part of the fan-shaped deformed plate of the flexible plate provided by the embodiment of the present application is connected with the hub connecting piece, the outer ring part of the fan-shaped deformed plate is provided with a fixed connecting hole, the connection between the flexible plate and other components is realized, the radial force deformed hole is provided on the fan-shaped deformed plate to provide a deformation amount, and the number of the fan-shaped deformed plate group is at least two, so that when the flexible plate needs to be connected with the input shaft of the gearbox, the hub body of the flexible plate adjusts the posture to realize the centering with the input shaft of the gearbox, at this time, the hub connecting piece fixed to the hub body will produce a small amount of displacement along with the adjustment of the posture of the hub body, the inner ring part of the corresponding fan-shaped deformed plate group will produce a small amount of displacement along with the hub connecting piece, and the outer ring part of the fan-shaped deformed plate group will not change the position due to the connection with other components outside the flexible plate, so as to make one or several fan-shaped deformed plate groups bear pressure in the radial direction, and the fan-shaped deformed plate groups in the opposite radial direction bear tension, the fan-shaped deformed plate groups are deformed by extrusion or stretching under the action of force, and the flexible plate and the input shaft of the gearbox are successfully connected. It can be seen that the flexible plate provided by the embodiment of the present application has the radial force deformed hole provided on the fan-shaped deformed plate of the fan-shaped deformed plate group, which can reduce the rigidity, and the fan-shaped deformed plate will be more easily deformed when subjected to the radial force; on the other hand, the number of the fan-shaped deformed plate group is at least two, and the fan-shaped deformed plate group is arranged in a circular ring shape, so that the entire deformed plate group has a split structure, the rigidity of the entire fan-shaped deformed plate group is reduced, and when subjected to the radial force, only part of the fan-shaped deformed plate group will be affected, and the remaining fan-shaped deformed plate groups will not produce additional additional forces on the forced fan-shaped deformed plate group, the deformation ability of the fan-shaped deformed plate group is improved, and the rigidity is reduced. Therefore, the flexible plate provided by the embodiment of the present application can provide eccentricity compensation, meet the connection requirements with the input shaft of the gearbox, and reduce the load attached to the hub after the connection is completed, so as to reduce the additional bending moment acting on the main bearing, and ensure the service life of the main bearing.

[0032] In an alternative, the vehicle and the flexible plate provided by the embodiment of the present application have deformation gaps between adjacent fan-shaped deformation plate groups of the flexible plate. In this way, when the fan-shaped deformation plate groups are deformed under the action of the radial force, the fan-shaped deformation plate groups are compressed or stretched in the radial direction, and at the same time, deformation in the circumferential direction is generated, including the extension deformation generated due to the extrusion. The deformation gaps provided between the adjacent fan-shaped deformation plate groups provide space for the circumferential deformation of the fan-shaped deformation plate groups, and the fan-shaped deformation plate groups will not be extruded with the adjacent fan-shaped deformation plate groups due to insufficient deformation space, thereby increasing the additional force.

[0033] In an alternative, the vehicle and the flexible plate provided by the embodiment of the present application have radial force deformation holes of the flexible plate arranged in the outer ring part of the fan-shaped deformation plate. In this way, under the action of the same force, the deformation amount of the radial force deformation hole located in the outer ring part of the fan-shaped deformation plate is larger, so that when the required deformation amount is determined, if the radial force deformation hole is located in the outer ring part of the fan-shaped deformation plate, only a smaller eccentric compensation force is generated, so that after the installation is completed, the reaction force additionally applied to the hub is also smaller, thereby further reducing the additional bending moment acting on the main bearing.

[0041] As known from the background art, in a hybrid vehicle, the connection of the flexible plate and the input shaft of the transmission causes the main bearing to bear an additional bending moment.

[0042] Please refer to Figure 2 , Figure 2 is a structural schematic view of a flexible plate, Figure 3 is Figure 2 a sectional view of

[0043] As shown in the figure, the flexible plate 1 includes a bent plate 12, two flat plates 10, and a hub 11, the bent plate 12 and the flat plates 10 are connected through rivets 13 at the outer peripheral portions, and the bent plate 12, the flat plates 10, and the hub 11 are connected through rivets 13 at the intermediate portions.

[0044] When the flexible plate 1 is connected with the input shaft (not shown in the figure) of the transmission, since the two cannot be completely centered, the flat plates 10 of the flexible plate 1 are deformed on the side in the direction of the radial force, eccentric compensation is performed from the radial direction of the flexible plate 1, and the smooth connection of the hub 11 of the flexible plate 1 and the input shaft of the transmission is ensured.

[0045] Since the radius stiffness of the flat plates 10 is greater than the stiffness of the input shaft of the transmission, additional load is added to the hub 11, and an additional bending moment acting on the main bearing is generated.

[0046] In order to reduce the additional bending moment borne by the main bearing, the embodiment of the present application provides a flexible plate, comprising: a hub, comprising a hub body and a hub connecting piece fixed to the outer peripheral portion of the hub body; and a fan-shaped deformation plate group, comprising at least one fan-shaped deformation plate, an inner annular surface of the fan-shaped deformation plate matches an outer peripheral surface of the hub body, the fan-shaped deformation plate is provided with a radial force deformation hole, an inner annular portion of the fan-shaped deformation plate is connected with the hub connecting piece, an outer annular portion of the fan-shaped deformation plate is provided with a fixed connection hole, the number of the fan-shaped deformation plate groups is at least two, and the fan-shaped deformation plate groups are arranged in a circular ring shape.

[0047] The flexible plate provided by the embodiment of the present application can provide eccentric compensation, meet the connection requirement with the input shaft of the variable box, and reduce the load attached to the wheel hub after the connection is completed, so that the additional bending moment acting on the main bearing can be reduced, and the service life of the main bearing is ensured.

[0048] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0049] It should be noted that the indicated position or location relationship in the embodiments of the present application is based on the position or location relationship shown in the drawings, which is only for the convenience of description and simplification of description, and does not indicate or imply that the device must have a specific position or be constructed in a specific position, and therefore cannot be understood as a limitation on the present application.

[0050] Please refer to Figures 4-6 , Figure 4 is a structural schematic diagram of a flexible plate according to an embodiment of the present application, Figure 5 is an exploded schematic diagram of a flexible plate according to an embodiment of the present application; Figure 6 is a structural schematic diagram of a fan-shaped deformation plate of a flexible plate according to an embodiment of the present application.

[0051] As shown in the drawings, the flexible plate provided by the embodiment of the present application comprises: a wheel hub 21 comprising a wheel hub body and a wheel hub connecting piece fixed to the outer peripheral part of the wheel hub body; a fan-shaped deformation plate group 20 comprising at least one fan-shaped deformation plate 201 stacked in sequence, wherein the inner annular surface of the fan-shaped deformation plate 201 matches the outer peripheral surface of the wheel hub body, the fan-shaped deformation plate 201 is provided with a radial force deformation hole 2011 (shown in Figure 6 ), the inner annular part of the fan-shaped deformation plate 201 is connected with the wheel hub connecting piece, and the outer annular part of the fan-shaped deformation plate 201 is provided with a fixed connection hole 2014 (shown in Figure 6The number of the group of the fan-shaped deformed plates 20 is at least two and arranged in a circular ring.

[0052] The group of the fan-shaped deformed plates 20 described herein includes at least one fan-shaped deformed plate 201 which is sequentially stacked, which means that each of the fan-shaped deformed plates 201 is arranged in a stacking manner in a direction perpendicular to the plane of the fan-shaped deformed plate; the connection of the hub connecting piece with the inner ring part of the fan-shaped deformed plate 201 can be that a fan-shaped deformed plate connecting hole is formed on the hub connecting piece, and a hub connecting hole 2015 is formed on the fan-shaped deformed plate 201, and a rivet 23 is sequentially passed through the fan-shaped deformed plate connecting hole and the hub connecting hole 2015 to realize the connection of the two.

[0053] It can be understood that the fan-shaped deformed plate 201 described herein refers to a deformed plate which is entirely in the shape of a fan, and the radial edges of each fan-shaped deformed plate 201 can be arranged in a circular plate, which includes not only a strictly mathematical fan-shaped surface, but also a structure which is entirely in the shape of a fan but has deformation at the edge part, such as the structure shown in the embodiment of the present application, and other types of deformation. Figure 6 The inner ring part of the fan-shaped deformed plate 201 described herein refers to the part located at the side with smaller circumferential dimension of the fan-shaped deformed plate 201, and for the same reason, the inner ring part of the fan-shaped deformed plate 201 described herein refers to the part located at the side with larger circumferential dimension of the fan-shaped deformed plate 201.

[0054] In addition, the specific shape of the radial force deformed hole 2011 described herein is not limited, as long as it can be deformed under the action of the radial force.

[0055] In this way, the flexible plate provided by the embodiment of the present application is connected with the hub connecting piece at the inner ring part of the fan-shaped deformed plate 201, the outer ring part of the fan-shaped deformed plate 201 is provided with a fixed connecting hole 2014 to realize the connection of the flexible plate with other components, the radial force deformed hole 2011 is formed on the fan-shaped deformed plate 201 to provide a deformation amount, and the number of the group of the fan-shaped deformed plates 20 is at least two, so that when the flexible plate needs to be connected with the input shaft of the gearbox, the hub body of the flexible plate adjusts the posture to realize the centering with the input shaft of the gearbox, at this time, the hub connecting piece fixed with the hub body will produce a small amount of displacement with the adjustment of the posture of the hub body, the inner ring part of the group of the fan-shaped deformed plates 20 at the corresponding position will produce a small amount of displacement with the hub connecting piece, and the outer ring part of the group of the fan-shaped deformed plates 20 will not change the position because it is connected with other components outside the flexible plate, thereby making one or more groups of the fan-shaped deformed plates 20 bear pressure in the radial direction thereof, and the groups of the fan-shaped deformed plates 20 opposite to them bear tension, under the action of the force, the group of the fan-shaped deformed plates 20 is deformed by extrusion or stretching, thereby ensuring the smooth connection of the flexible plate with the input shaft of the gearbox.

[0056] It can be seen that the flexible plate provided by the embodiment of the present application has the following advantages: on the one hand, the radial force deformation hole 2011 is further arranged on the fan-shaped deformation plate 201 of the fan-shaped deformation plate group 20, so that the rigidity can be reduced, and the fan-shaped deformation plate 201 can be deformed more easily when subjected to the radial force; on the other hand, the number of the fan-shaped deformation plate group 20 is at least two, and the fan-shaped deformation plate group 20 is arranged in a circular ring shape, so that the entire deformation plate group has a split structure, the rigidity of the entire fan-shaped deformation plate group 20 is reduced, and when subjected to the radial force, only the part of the fan-shaped deformation plate group 20 is affected, and the remaining fan-shaped deformation plate group 20 does not generate additional additional force on the fan-shaped deformation plate group 20 subjected to the force, so that the deformation ability of the fan-shaped deformation plate group 20 is improved, and the rigidity is reduced. Therefore, the flexible plate provided by the embodiment of the present application can provide eccentric compensation, meet the connection requirements with the input shaft of the variable box, and after the connection is completed, the load attached to the hub is reduced, so that the additional bending moment acting on the main bearing can be reduced, and the service life of the main bearing is ensured.

[0057] Please continue to refer to Figure 4 It can be seen that in a specific embodiment, the flexible plate provided by the embodiment of the present application has a deformation gap between adjacent fan-shaped deformation plate groups 20.

[0058] It is easy to understand that each fan-shaped deformation plate group 20 is arranged in a circular ring shape, so that the deformation gap between adjacent fan-shaped deformation plate groups 20 is a gap in the circumferential direction.

[0059] The flexible plate provided by the embodiment of the present application has a deformation gap between adjacent fan-shaped deformation plate groups 20, and when the fan-shaped deformation plate group 20 is deformed under the action of the radial force, it is compressed or stretched in the radial direction, and at the same time, it is deformed in the circumferential direction, including the extension deformation caused by extrusion. The deformation gap between adjacent fan-shaped deformation plate groups 20 provides space for the circumferential deformation of the fan-shaped deformation plate group 20, so that extrusion does not occur between adjacent fan-shaped deformation plate groups 20 due to insufficient deformation space, thereby increasing additional force.

[0060] Please continue to refer to Figure 6 In another specific embodiment, the flexible plate provided by the embodiment of the present application has a radial force deformation hole 2011 arranged in the outer ring portion of the fan-shaped deformation plate.

[0061] In this way, the deformation of the radial force deformation hole 2011 located at the outer ring of the fan-shaped deformation plate 201 is greater under the same force, so that, when the required deformation amount is determined, if the radial force deformation hole 2011 is located at the outer ring of the fan-shaped deformation plate 201, only a small eccentric compensation force is generated, so that after installation, the reaction force applied to the hub 21 is also small, thereby further reducing the additional bending moment acting on the main bearing.

[0062] As shown in Figure 6 In a specific embodiment, in order to facilitate the connection of other connecting components, the fan-shaped deformation plate 201 is also provided with a mounting avoidance hole 2012 located between the radial force deformation hole 2011 and the hub body. The provision of the mounting avoidance hole 2012 can also reduce the material used by the fan-shaped deformation plate 201, thereby reducing costs, and the provision of the mounting avoidance hole 2012 can also adjust the stiffness of the fan-shaped deformation plate 201 to better meet the needs of radial eccentric compensation.

[0063] It can be understood that the shape of the mounting avoidance hole 2012 is not limited by the embodiments of the present application, as long as it can achieve the need of mounting avoidance. Alternatively, in order to prevent stress concentration at the connection part of different sides of the mounting avoidance hole 2012, a circular arc connection can be formed at the above-mentioned part.

[0064] In a specific embodiment, the mounting avoidance hole 2012 can include a first mounting avoidance hole and a second mounting avoidance hole arranged in the diameter direction, and a torque rib 2013 is arranged between the first mounting avoidance hole and the second mounting avoidance hole. The provision of the torque rib 2013 can ensure that the fan-shaped deformation plate 201 bears torque, ensures the transmission of torque, and makes the first mounting avoidance hole and the second mounting avoidance hole arranged in the radial direction, so that the torque rib 2013 extends in the circumferential direction, better bearing torque.

[0065] Please continue to refer to Figure 6 In a specific embodiment, the first mounting avoidance hole is in communication with the radial force deformation hole 2011. Thus, when subjected to radial force, the first mounting avoidance hole and the radial force deformation hole 2011 can jointly deform. Of course, in other embodiments, the radial force deformation hole 2011 can be a single closed hole.

[0066] As mentioned above, the flexible plate provided by the embodiment of the present application comprises at least two fan-shaped deformation plate groups 20, in order to better realize deformation and reduce additional force on the hub, the number of the fan-shaped deformation plate groups 20 can range from 3 to 8, such as 4, 5 or 6, etc. If the number of the fan-shaped deformation plate groups 20 is too small, one fan-shaped deformation plate group 20 will occupy a large part of the annular shape, thus the rigidity is relatively large and the possibility of generating additional force is increased, while if the number of the fan-shaped deformation plate groups 20 is too large, the rigidity of the flexible plate is relatively small and cannot bear a relatively large force.

[0067] The size of each fan-shaped deformation plate group 20 can be completely the same or different, when the structure and size of each fan-shaped deformation plate group 20 are completely the same, the processing and installation are relatively simple.

[0068] Optionally, in the same fan-shaped deformation plate group 20, the number of the fan-shaped deformation plates 201 can range from 1 to 3. The number of the fan-shaped deformation plates 201 in the same fan-shaped deformation plate group 20 will also affect the rigidity of the fan-shaped deformation plate group 20, thus the specific number can be set according to the requirements of rigidity and thickness.

[0069] In the same fan-shaped deformation plate group 20, the shape and size of each fan-shaped deformation plate 201 can be completely the same or different, when the shape and size of each fan-shaped deformation plate 201 are the same, the processing and assembly requirements of the flexible plate are relatively low and the stress condition is better calculated and controlled.

[0070] Please continue to refer to Figure 6 In a specific embodiment, the fan-shaped deformation plate 201 comprises a fan-shaped plate and a connecting plate located in the same plane, the connecting plate is fixed to the outer peripheral part of the fan-shaped plate, the inner ring part of the fan-shaped plate is connected with the hub connecting piece, and the connecting plate is provided with the fixed connecting hole 2014. The setting of the connecting plate makes the fan-shaped deformation plate 201 use less material on the basis of ensuring connection, thereby further reducing the cost.

[0071] In order to facilitate connection, the inner ring part of the fan-shaped plate can be provided with a hub connecting hole 2015, the hub connecting piece is provided with a fan-shaped plate connecting hole (not shown in the figure), and the fan-shaped part and the hub connecting part are connected through a rivet 23 penetrating through the hub connecting hole 2015 and the fan-shaped plate connecting hole.

[0072] Of course, in another specific embodiment, as Figure 4 and Figure 5As shown, the flexible plate provided by the embodiment of the present application can further comprise a bending plate 22, wherein the outer ring part of the sector-shaped deformation plate 201 is connected with the bending plate 22, so as to further stabilize the outer ring part of the sector-shaped deformation plate 201.

[0073] To solve the above problems, the embodiment of the present application further provides a vehicle, which comprises a gearbox and the flexible plate as described above, wherein the input shaft of the gearbox is connected with the hub 21 of the flexible plate.

[0074] The vehicle provided by the embodiment of the present application has the input shaft of the gearbox connected with the hub 21 of the flexible plate, and the flexible plate comprises the sector-shaped deformation plate group 20 and the hub 21, the inner ring part of the sector-shaped deformation plate 201 of the sector-shaped deformation plate group 20 is connected with the hub connector of the hub 21, the outer ring part of the sector-shaped deformation plate 201 is provided with the fixed connection hole 2014, the connection between the flexible plate and other components is realized, the radial force deformation hole 2011 is provided on the sector-shaped deformation plate 201 for providing the deformation amount, and the number of the sector-shaped deformation plate group 20 is at least two, so that when the flexible plate needs to be connected with the input shaft of the gearbox, the hub body of the flexible plate adjusts the posture to realize the centering with the input shaft of the gearbox, at this time, the hub connector fixed with the hub body will produce a small amount of displacement along with the adjustment of the posture of the hub body, the inner ring part of the sector-shaped deformation plate group 20 at the corresponding position will produce a small amount of displacement along with the hub connector, and the outer ring part of the sector-shaped deformation plate group 20 will not change the position because it is connected with other components outside the flexible plate, thereby making one or several sector-shaped deformation plate groups 20 bear the pressure in the radial direction thereof, and the sector-shaped deformation plate groups 20 in the opposite radial direction thereof bear the tension, under the action of the force, the sector-shaped deformation plate group 20 produces the extrusion deformation or the tensile deformation, and the smooth connection between the flexible plate and the input shaft of the gearbox is ensured.

[0075] It can be seen that the vehicle provided by the embodiment of the present application has the following advantages: on the one hand, the radial force deformation hole 2011 is further provided on the sector-shaped deformation plate 201 of the sector-shaped deformation plate group 20, so as to reduce the rigidity, and when the radial force acts, the sector-shaped deformation plate 201 will be more easily deformed; on the other hand, the number of the sector-shaped deformation plate group 20 is at least two, and the sector-shaped deformation plate group 20 is arranged in a circular ring shape, so that the entire sector-shaped deformation plate group has a split structure, the rigidity of the entire sector-shaped deformation plate group 20 is reduced, and when the radial force acts, only the sector-shaped deformation plate group 20 in the part will be affected, and the remaining sector-shaped deformation plate groups 20 will not produce additional additional forces on the sector-shaped deformation plate group 20 under stress, the deformation capacity of the sector-shaped deformation plate group 20 is improved, and the rigidity is reduced, therefore, the flexible plate provided by the embodiment of the present application can provide the eccentricity compensation, meet the connection requirement with the input shaft of the gearbox, and after the connection is completed, the load attached to the hub is reduced, so that the additional bending moment acting on the main bearing can be reduced, and the service life of the main bearing is ensured.

Any modifications and changes can be made without departing from the spirit and scope of the application. The scope of the application should be limited only by the scope of the claims.
