Description

Technical Field

[0001] The present invention relates to the field of vehicles, and particularly to a powertrain mounting bracket and a vehicle. Background Art

[0002] In an automotive structure, the powertrain includes an engine, a clutch, and a gearbox, which is the source of the vehicle's power. Transmitting its power to the drive train can support the operation of the entire vehicle. During operation, the engine converts the reciprocating motion of the piston into the rotary motion of the crankshaft, and outputs power to the drive train through the transmission and speed reduction and torque increase of the clutch and gearbox. During this process, the powertrain itself generates vibrations and transmits them to the vehicle body through the attachment points, causing vibrations and noises inside the vehicle, which is not conducive to improving the NVH state and comfort inside the vehicle. To address such problems, generally, rubber mounts are currently used to connect the powertrain and the vehicle frame, and the elastic damping of the rubber mounts is used to reduce the transmission of vibrations. However, this structure only achieves single-stage vibration reduction, and there are still relatively large vibrations transmitted to the vehicle frame and then to the vehicle body through the rubber mounts, and the vibration reduction effect is limited. Summary of the Invention

[0003] The purpose of the present invention is to provide a powertrain mounting bracket to solve the problem that the existing vehicle powertrain transmits relatively large vibrations to the vehicle body and has a poor vibration reduction effect. At the same time, the present invention also provides a vehicle to solve the problem that the vibrations transmitted from the existing vehicle powertrain to the vehicle body are relatively intense and the comfort is poor.

[0004] The powertrain mounting bracket of the present invention includes a mounting frame, which includes left and right longitudinal beams (3) and front and rear connecting beams respectively connecting the front and rear ends of the left and right longitudinal beams (3). The middle space surrounded by the left and right longitudinal beams (3) and the front and rear connecting beams is used to accommodate the powertrain (100); a primary mount and a secondary mount are respectively provided on the mounting frame. The primary mount is used to connect with the powertrain (100) and includes a primary front mount and a primary rear mount; the secondary mount is provided on the mounting frame and is used to connect with the vehicle frame.

[0005] The present invention provides a brand-new powertrain mounting bracket. The middle space of the powertrain mounting bracket can fixedly install the powertrain through the primary mount and be fixedly connected to the vehicle frame through the secondary mount, thus realizing the fixed installation of the powertrain and the vehicle frame bracket, achieving two-stage vibration reduction, being able to better weaken the vibrations transmitted from the powertrain to the vehicle frame during operation, and further improving the vibration reduction effect and the comfort of the vehicle.

[0006] Furthermore, the powertrain mounting bracket further includes a bracket connecting the left and right longitudinal beams. The bracket is located between the front and rear connecting beams, and the primary rear mount is provided on the bracket. By using the bracket to support and fix the powertrain, the reliability of the powertrain installation is ensured, and the safety of the vehicle during operation is improved.

[0007] Furthermore, the bracket is of a concave structure, and the first-stage rear mounts are paired left and right and are arranged obliquely opposite to each other. The concave sunken design can better accommodate the powertrain and fit more tightly with the powertrain. The oblique opposite arrangement of the first-stage rear mounts can attenuate vibrations in more directions and optimize the vibration damping effect.

[0008] Furthermore, the two ends of the bracket are respectively connected to the outer side surfaces of the corresponding longitudinal beams. This not only facilitates the connection between the bracket and the longitudinal beams, but also forms a larger accommodation space between the bracket and the two longitudinal beams to accommodate the powertrain.

[0009] As an optimized solution, there are three second-stage mounts. Two of them are respectively arranged at the positions near the front ends of the left and right longitudinal beams, and the other is arranged in the middle of the rear connection beam. Such a three-point arrangement similar to the three vertices of an isosceles triangle is not only more stable and reliable in connection with the vehicle frame, but also has a better vibration damping effect.

[0010] As a further optimized solution, the two second-stage mounts on the left and right longitudinal beams are respectively arranged on the outer sides of the corresponding longitudinal beams. This not only facilitates the connection with the vehicle frame, but also does not occupy the middle space of the mount frame, which is beneficial to the fixed installation of the powertrain in the mount frame.

[0011] Further, the rear connection beam is of a convex structure, and the rear mount arranged on it is located below the highest point in the middle of the rear connection beam. One of the three second-stage mounts, the rear mount, and the two front mounts are staggered in height, which can better achieve vibration damping between the mount frame and the vehicle frame.

[0012] Furthermore, the two second-stage mounts on the front side include a vertical connection frame, a mount buffer pad, and a vehicle frame connection bracket. The vertical connection frame is connected to the outer side surface of the corresponding longitudinal beam. The mount buffer pad is connected between the vertical connection frame and the vehicle frame connection bracket, and the vehicle frame connection bracket is connected to the mount buffer pad through a connection long hole extending in the left-right direction. This mount structure can more conveniently realize the connection between the mount frame and the vehicle frame and can adapt to machining and assembly errors.

[0013] In addition, the first-stage front mounts are paired left and right and are respectively fixedly connected to the corresponding longitudinal beams. The first-stage front mounts include a support frame connected to the corresponding longitudinal beam, a mount buffer pad connected to the support frame, and a powertrain connection bracket connected to the mount buffer pad. The support frame is connected to the mount buffer pad through a connection long hole extending in the left-right direction. This mount structure can conveniently realize the connection between the mount frame and the powertrain and utilize machining and assembly errors.

[0014] The technical solution of the vehicle of the present invention:

[0015] The vehicle includes a frame, a powertrain (100), and a powertrain mounting bracket; the powertrain (100) is installed on the powertrain mounting bracket and is installed on the frame through the powertrain mounting bracket; wherein the powertrain mounting bracket includes: a mounting frame, the mounting frame includes left and right longitudinal beams (3) and front and rear connecting beams respectively connecting the front and rear ends of the left and right longitudinal beams (3), and the middle space surrounded by the left and right longitudinal beams (3) and the front and rear connecting beams is used to accommodate the powertrain (100); a primary mount and a secondary mount are respectively provided on the mounting frame, the primary mount is used to connect with the powertrain (100) and includes a primary front mount and a primary rear mount; the secondary mount is arranged on the mounting frame and is used to connect with the frame.

[0016] The present invention improves the assembly structure of the powertrain of the vehicle. The middle space of the powertrain mounting bracket can fixedly install the powertrain through the primary mount and is fixedly connected to the frame through the secondary mount. In this way, the fixed installation of the powertrain and the frame bracket is realized, and two-stage vibration damping is achieved, which can better weaken the vibration transmitted from the powertrain to the frame during operation, thereby improving the vibration damping effect and the comfort of the vehicle.

[0017] Furthermore, the powertrain mounting bracket further includes a bracket connecting the left and right longitudinal beams. The bracket is located between the front and rear connecting beams, and the primary rear mount is arranged on the bracket. By using the bracket to support and fix the powertrain, the reliability of the powertrain installation is ensured, and the safety of the vehicle during operation is improved.

[0018] Even further, the bracket is of a concave structure, the primary rear mounts are paired left and right and are arranged obliquely opposite to each other. The sunken design of the concave shape can better accommodate the powertrain and cooperate more tightly with the powertrain. The oblique relative arrangement of the primary rear mounts can attenuate vibrations in more directions and optimize the vibration damping effect.

[0019] Even further, the two ends of the bracket are respectively connected to the outer side surfaces of the corresponding longitudinal beams. This not only facilitates the connection between the bracket and the longitudinal beams, but also forms a larger accommodation space between the bracket and the two longitudinal beams to accommodate the powertrain.

[0020] As an optimized solution, there are three secondary mounts, two of which are respectively arranged at positions close to the front ends of the left and right longitudinal beams, and the other is arranged in the middle of the rear connecting beam. Such a three-point arrangement similar to the three vertices of an isosceles triangle not only connects to the frame more firmly and reliably, but also has a better vibration damping effect.

[0021] As a further optimized solution, the two secondary mounts on the left and right longitudinal beams are respectively arranged on the outer sides of the corresponding longitudinal beams. This not only facilitates the connection with the frame, but also does not occupy the middle space of the mounting frame, which is beneficial to the fixed installation of the powertrain in the mounting frame.

[0022] Furthermore, the rear connecting beam is a convex structure, and the rear mount disposed thereon is located below the highest point in the middle of the rear connecting beam. One of the three secondary mounts, the rear mount, is at a different height from the two front mounts, which can better achieve vibration reduction between the mount frame and the vehicle frame.

[0023] Even further, the two secondary mounts on the front side include a vertical connecting frame, a mount buffer pad, and a vehicle frame connecting bracket. The vertical connecting frame is connected to the outer side surface of the corresponding longitudinal beam. The mount buffer pad is connected between the vertical connecting frame and the vehicle frame connecting bracket, and the vehicle frame connecting bracket is connected to the mount buffer pad through a connecting long hole extending in the left-right direction. This mount structure can more conveniently achieve the connection between the mount frame and the vehicle frame and can adapt to machining and assembly errors.

[0024] In addition, the primary front mounts are in pairs on the left and right and are respectively fixedly connected to the corresponding longitudinal beams. The primary front mounts include a support frame connected to the corresponding longitudinal beam, a mount buffer pad connected to the support frame, and a power assembly connecting bracket connected to the mount buffer pad. The support frame is connected to the mount buffer pad through a connecting long hole extending in the left-right direction. This mount structure can conveniently achieve the connection between the mount frame and the power assembly and can utilize machining and assembly errors. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The features and performance of the present invention will be further described in detail below with reference to the embodiments.

[0036] Specific Embodiment One of the Vehicle of the Present Invention:

[0037] The vehicle of this embodiment includes a vehicle frame, and a power assembly, a transmission system, a running system, etc. are configured on the vehicle frame. Among them, the power assembly is fixedly installed on the power assembly mounting bracket, and the power assembly mounting bracket is fixedly connected to the vehicle frame, so as to realize the fixed assembly of the power assembly on the vehicle frame. And more importantly, the power assembly is fixedly connected to the power assembly mounting bracket through a primary mount, and the power assembly mounting bracket is fixedly connected to the vehicle frame through a secondary mount, thereby forming a two-stage vibration damping structure between the power assembly and the vehicle frame, effectively reducing the vibration transmitted from the power assembly to the vehicle frame.

[0038] Figure 1It shows the structure when the powertrain 100 is fixedly installed on the powertrain mounting bracket. Specifically, the powertrain includes an engine, a clutch, and a transmission. The three are integrally designed and assembled into an overall module. There are four fixed connection points on this overall module, and it is fixedly installed on the powertrain mounting bracket through these four fixed connection points.

[0039] The structure of the powertrain mounting bracket and the structure of the components installed thereon are as Figures 2 - 6 shown. The powertrain mounting bracket includes two left and right longitudinal beams 3 arranged in parallel at intervals. A front connecting beam 4 is connected between the two left and right longitudinal beams 3 at the front end position, and a rear connecting beam 9 is connected at the rear end position. The left and right longitudinal beams 3 and the front and rear connecting beams together enclose a frame structure, which serves as the main structure of the powertrain mounting bracket. The middle space of the frame structure is used to accommodate the powertrain installed on the powertrain mounting bracket.

[0040] A bracket 10 is connected between the two left and right longitudinal beams 3 at the middle position. Two primary rear mounts 11 are fixedly connected to the bracket 10. Primary front mounts are also fixedly connected to the two left and right connecting beams 3 respectively near the front end position. The two primary rear mounts and the two primary front mounts respectively correspond to the four fixed connection points of the powertrain one by one. Therefore, the powertrain can be fixedly connected to the powertrain mounting bracket through the four primary mounts.

[0041] Specifically, the primary front mount includes a support frame 2. The support frame 2 includes a vertical plate body and an extended connection plate connected to one side surface of the vertical plate body. The vertical plate body is used to be fixedly connected to the inner side surface of the corresponding longitudinal beam through a bolt assembly. A suspension buffer pad 7 is fixedly connected to the extended connection plate. A powertrain connection bracket 1 is fixedly connected to the suspension buffer pad 7 for fixedly connecting the powertrain 100. The primary rear mount 11 includes two relatively spaced fixed connection plates. A damping rubber pad is clamped between the two fixed connection plates. One of the two fixed connection plates is connected to the bracket 10, and the other is used to connect to the corresponding fixed connection point on the powertrain 100.

[0042] From Figure 2 it can also be clearly seen that the two primary front mounts are respectively fixedly installed on the inner sides of the corresponding left and right longitudinal beams 3. The extended connection plates of the support plates 2 are bent structures, including a horizontal section and an inclined section. The inclined section slopes downward from outside to inside. The inclined sections of the two support plates 2 are arranged close to each other, and connection long holes extending along the inclined direction are provided on both of them. The suspension buffer pad 7 is connected to the inclined section of the extended connection plate through the connection long holes. Among them, the specific structure of the suspension buffer pad 7 is as Figure 5As shown in the figure, it includes upper and lower fixed connection seats and a suspension rubber pad 73 fixed between the upper and lower fixed connection seats. An upper connection bolt 72 is provided on the upper fixed connection seat, and a lower connection bolt 71 is provided on the lower fixed connection seat. The lower connection bolt 71 is used to pass through a connecting long hole on the outer extension connecting plate, and the upper connection bolt 72 is used to connect to the power assembly connection bracket 1. It should be noted that the two first-level suspensions have the same structure and are symmetrically arranged left and right. Figure 2 In order to clearly show the suspension buffer pad 7, among the two first-level front suspensions, only one shows the connection bracket 1 connected thereto, and the connection bracket connected to the other is omitted to expose the suspension buffer pad.

[0043] The bracket 10 has a concave structure, which is generally similar to a V shape or a U shape. The two ends of the bracket 10 are respectively fixedly connected to the outer sides of the two left and right longitudinal beams 3, and the two first-level rear suspensions 11 are arranged obliquely opposite to each other. Such a structural arrangement can better support and fix the power assembly in the middle space of the frame structure.

[0044] In this way, when the power assembly 100 is fixedly connected to the power assembly suspension frame through four first-level suspensions, the four first-level suspensions respectively support the power assembly 100 from the front and rear ends of the power assembly 100 in an obliquely opposite manner, and weaken the vibration transmission from the power assembly 100 to the power assembly suspension frame through the buffer structures of each first-level suspension.

[0045] In addition, second-level suspensions are also arranged on the frame structure of the power assembly suspension frame, and the power assembly suspension frame is fixedly connected to the vehicle frame through the second-level suspensions.

[0046] In this embodiment, there are three second-level suspensions. Two of them are respectively fixedly connected to the positions near the front ends of the corresponding left and right longitudinal beams 3 and are located on the outer sides of the corresponding longitudinal beams, which are called second-level front suspensions. The other one is arranged on the rear connection beam 9 and is located in the middle of the rear connection beam 9, which is called the second-level rear suspension 79.

[0047] The two second-level front suspensions include a vertical connection frame 5, a suspension buffer pad 7, and a vehicle frame connection bracket 8. The vertical connection frame 5 is connected to the outer side surface of the corresponding longitudinal beam, and the suspension buffer pad 7 is connected between the vertical connection frame 5 and the vehicle frame connection bracket 8.

[0048] Among them, the vertical connection frame 5 includes a vertical connection plate and a lug 6 provided at the upper end of the vertical connection plate. The specific structure of the lug 6 is as Figure 6As shown, it includes a horizontal connecting ear plate 61 and a vertical connecting ear plate 62 connected to one side edge of the horizontal connecting ear plate 61. The length of the vertical connecting ear plate 62 is greater than that of the horizontal connecting ear plate 61. Reinforcing end plates for connecting the vertical connecting ear plate 62 and the horizontal connecting ear plate 61 are respectively arranged at both ends of the horizontal connecting ear plate 61. Connecting holes are respectively arranged on the horizontal connecting ear plate 61 and the vertical connecting ear plate 62 for respectively connecting a vertical connecting plate and the upper end of a suspension cushion 7.

[0049] The structure of the vehicle frame connection bracket 8 is as Figure 4 shown, which is the same as the structure of the support frame 2, including a connecting vertical plate 81 and an extended connecting plate arranged on one side surface of the connecting vertical plate 81. The connecting vertical plate 81 is used for fixedly connecting with the vehicle frame. The extended connecting plate has a horizontal section and an inclined section. A connecting long hole 80 extending along the inclined direction is arranged on the inclined section. The vehicle frame connection bracket 8 is connected to the lower end of the suspension cushion 7 through the connecting long hole 80 on its inclined section, so that the two secondary front suspensions can also support between the vehicle frame and the powertrain suspension bracket in an inclined posture.

[0050] Specifically, the rear connecting beam 9 is a U-shaped upward convex structure opposite to the form of the bracket 10. The secondary rear suspension 79 arranged on it is located below the highest point in the middle of the rear connecting beam 9, so that the three-point suspension of the powertrain suspension bracket and the vehicle frame is arranged in a triangle and staggered in height, and thus the vibration reduction between the powertrain suspension bracket and the vehicle frame can be better realized.

[0051] Through the introduction of the two-stage vibration reduction structure in the vehicle introduced above, the vibration transmitted from the powertrain to the vehicle frame is further reduced, and the NVH state of the whole vehicle is improved; at the same time, the powertrain and the powertrain suspension bracket can be assembled as a whole and then connected to the vehicle frame, improving the installation efficiency of the whole vehicle; moreover, the powertrain and the powertrain suspension bracket form a module as a whole and are installed on the vehicle frame. Compared with the original direct installation of the powertrain on the vehicle frame, the weight of the whole power module is increased, which helps to reduce the amplitude and transmission of vibration and is also beneficial to improving the NVH state of the whole vehicle.

[0052] The vehicle of the present invention is not limited to the embodiments introduced above. Based on the design concept of the present invention, there can be various deformation embodiments.

[0053] For example, in other embodiments, different from the first embodiment introduced above, according to the different distribution positions of the fixed working connection points on the powertrain, the layout form of the primary suspension can also be different; there can be multiple groups of primary suspensions arranged at intervals in the front-rear direction, and each group of primary suspensions has more than two and is arranged at intervals in the left-right direction; or, the primary suspension can include multiple ones and form multiple vertices such as a triangle or a pentagon or a hexagon to jointly support the powertrain.

[0054] Similarly, in other embodiments, different from Embodiment 1 introduced above, the number and distribution form of the secondary mounts can also be changed according to actual needs. For example, there are four or six secondary mounts, which are divided into two groups and installed on the left and right longitudinal beams respectively; or there are six secondary mounts, four of which are divided into two groups and symmetrically installed on the left and right longitudinal beams, and the other two are respectively on the front and rear connecting beams.

[0055] For example, in other embodiments, different from Embodiment 1 introduced above, the bracket can be a straight structure, located on the lower side of the left and right longitudinal beams, and both ends are fixedly connected to the lower side surfaces of the left and right longitudinal beams respectively. The primary rear mount is fixedly installed on the upper side surface of the bracket and is also in a horizontal state; the rear connecting beam is also a straight structure, located on the upper side of the left and right connecting beams, and both ends are fixedly connected to the upper side surfaces of the left and right longitudinal beams respectively. The secondary rear mount is fixedly installed in the middle of the lower side of the rear connecting beam.

[0056] Or in other embodiments, different from Embodiment 1 introduced above, the two secondary mounts on the left and right longitudinal beams are arranged on the lower side of the corresponding longitudinal beams, and the two primary mounts on the left and right longitudinal beams are arranged on the upper side of the corresponding longitudinal beams.

[0057] Or, in other embodiments, different from Embodiment 1 introduced above, the structure of the support frame of the primary front mount is different from that of the vehicle frame connection bracket of the secondary front mount, and the structure of the power assembly connection bracket of the primary front mount is different from that of the lug of the secondary front mount. Specifically, it can be determined according to the connection method between the power assembly mount and the power assembly and the vehicle frame, and can be conventionally designed by those skilled in the art.

[0058] The specific embodiment of the power assembly mount of the present invention has the same specific structure as the power assembly mount in the embodiment of the vehicle introduced above, and will not be described in detail herein.

[0059] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. The patent protection scope of the present invention is subject to the claims. All equivalent structural changes made by using the description and drawings of the present invention should be equally included in the protection scope of the present invention.
