Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a transmission suspension and a vehicle. Background Art

[0002] The powertrain itself is an internal vibration source, and is also subject to various external vibration interferences, which put it in a complex vibration state, causing damage to surrounding parts and riding discomfort. People use rubber to isolate vibrations, and gradually evolved into designing suspensions to isolate and attenuate the vibration transmission of the powertrain.

[0003] In the related technology, the transmission mount is applied to traditional fuel or hybrid vehicles, and is often used to support and isolate the powertrain. At present, the inner core of the transmission mount is generally fixed in place through the threaded mounting hole in the center, so the inner core is easy to shake when subjected to forces in different directions, thus affecting the normal vibration isolation effect of the mount.

To this end, one purpose of the utility model is to provide a transmission suspension, which can enhance the connection and fastening strength of the inner core, prevent the problem of following the rotation when fastening the inner core, and enable the inner core to fully isolate the vibration generated by the transmission from different directions, so as to prevent the transmission suspension from being subjected to uneven force and causing local damage.

[0005] The utility model further provides a vehicle.

[0006] The transmission suspension according to the first aspect of the utility model includes: a bracket, the bracket is formed with a first mounting cavity; an exoskeleton, the exoskeleton is arranged in the first mounting cavity; a main spring, the main spring is arranged in the exoskeleton; an inner core, the inner core is connected to the inside of the main spring, the inner core is provided with a plurality of first mounting holes arranged at intervals, and the cross-section of the inner core perpendicular to the axis of the first mounting hole is polygonal; a limit member, the limit member is arranged at one axial end of the exoskeleton, the limit member is provided with a plurality of second mounting holes, the plurality of first mounting holes correspond one to one with the plurality of second mounting holes, so as to be suitable for fasteners to penetrate the first mounting holes and the second mounting holes to connect the limit member with the inner core.

[0007] In the above technical solution, compared with the traditional arrangement of a single bolt hole in the middle of the inner core, the embodiment in this case arranges multiple first mounting holes at intervals on the inner core, which can increase the installation force position of the inner core and the transmission, thereby increasing the connection and fastening strength between the inner core and the transmission, and can also effectively prevent the problem of the inner core rotating due to a single bolt being subjected to external force, thereby ensuring the position stability of the inner core. In addition, the cross-section of the inner core perpendicular to the axis of the first mounting hole is constructed as a polygon, which makes it easier for the inner core to more accurately match the vibration frequency characteristics of the transmission in different directions. The contact area can be increased through the layout of different planes and angles, and the absorption capacity of specific frequency vibrations can be enhanced, thereby more effectively isolating the vibration generated during the operation of the transmission, reducing the vibration energy transmitted from the transmission to the vehicle body, and improving ride comfort; and compared with a simple circular or single-shaped inner core, the polygonal structure can provide better torsion resistance and stability while maintaining sufficient elasticity, that is, when the inner core is subjected to forces in different directions, the polygonal structure can distribute the load more evenly, reduce local stress concentration, and improve durability; and on each side or corner of the polygonal inner core, the elastic characteristics of the transmission suspension in different directions can be controlled by adjusting the material or design details, thereby achieving more precise control within the small movement range of the powertrain, helping to maintain the correct alignment of the engine and transmission and reduce mechanical wear.

[0038] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0039] Reference below Figure 1-Figure 10The transmission suspension 100 according to the embodiment of the utility model is described, which can enhance the connection and fastening strength at the inner core 4, prevent the problem of following rotation when fastening the inner core 4, and enable the inner core 4 to fully isolate the vibration generated by the transmission from different directions, thereby preventing the transmission suspension 100 from being subjected to uneven force and causing local damage.

[0040] Combination Figure 1-Figure 10 As shown, the transmission suspension 100 according to the embodiment of the first aspect of the utility model includes a bracket 1, an outer skeleton 2, a main spring 3, an inner core 4 and a limiter 5. Among them, the bracket 1 is mainly used as the installation support structure of the transmission suspension 100, which can provide installation space and protection for related structures, and can also establish a connection relationship with the frame. The outer skeleton 2 can be used as a mounting support carrier for the main spring 3. The spring leaf is mainly used to absorb and dissipate the vibration energy generated when the transmission is running (it cushions the impact through elastic deformation and reduces the vibration directly transmitted to the frame). The inner core 4 directly bears the weight and dynamic load of the transmission (it is fixed in the shell through the rubber part of the main spring 3), and the inner core 4 can ensure the precise positioning of the transmission at a predetermined position, while allowing a certain degree of displacement to offset vibration.

[0041] Specifically, the bracket 1 is formed with a first mounting cavity 11, the outer frame 2 is arranged in the first mounting cavity 11, the main spring 3 is arranged in the outer frame 2, the inner core 4 is connected to the inside of the main spring 3, and the inner core 4 is provided with a plurality of first mounting holes 41 arranged at intervals. The cross-section of the inner core 4 perpendicular to the axis of the first mounting hole 41 is polygonal, and the limit member 5 is arranged at one axial end of the outer frame 2. The limit member 5 is provided with a plurality of second mounting holes 51. The plurality of first mounting holes 41 correspond to the plurality of second mounting holes 51 one by one, so as to be suitable for connecting the limit member 5 with the inner core 4 after the fasteners pass through the first mounting holes 41 and the second mounting holes 51.

[0042] Specifically, the bracket 1 can firmly connect the transmission suspension 100 to the vehicle frame, the exoskeleton 2 is circumferentially connected to the inner wall of the first installation cavity 11, the main spring 3 is arranged in the exoskeleton 2 (usually the main spring 3 is vulcanized inside the exoskeleton 2, and then the exoskeleton 2 is pressed into the first installation cavity 11 of the bracket 1), and the inner core 4 is connected to the inside of the main spring 3. The inner core 4 is directly connected to the transmission, and the inner core 4 will be directly subjected to the dynamic load from the transmission. Since the main spring 3 connected to the inner core 4 is an elastic material, the main spring 3 can undergo elastic deformation to buffer the dynamic load force on the inner core 4, thereby reducing the vibration energy directly transmitted from the transmission to the vehicle body, thereby maintaining the driving stability and comfort of the entire vehicle.

[0043] Among them, the fastener can be sequentially penetrated through the second mounting hole 51 on the limit member 5, the first mounting hole 41 on the inner core 4 and the transmission to connect the three as a whole. In this way, the limit member 5 can increase the weight and spatial mode of the inner core 4, thereby improving the structural strength and bending and torsional stiffness of the inner core 4. It can also avoid the fastener directly concentrating the force on the inner core 4 to damage the local outer surface of the inner core 4 (that is, the fastening force of one axial end of the fastener is evenly dispersed on the limit member 5), thereby improving the structural reliability and force uniformity of the inner core 4.

[0044] Furthermore, compared with the traditional arrangement of setting a single bolt hole in the middle of the inner core, the embodiment in this case sets a plurality of first mounting holes 41 at intervals on the inner core 4. This can increase the installation force position of the inner core 4 and the transmission, thereby increasing the connection and fastening strength between the inner core 4 and the transmission, and can also effectively prevent the problem of the inner core 4 rotating due to a single bolt being subjected to external force, thereby ensuring the position stability of the inner core 4.

[0045] Furthermore, the cross-section of the inner core 4 perpendicular to the axis of the first mounting hole 41 is constructed as a polygon, so that the inner core 4 can more accurately match the vibration frequency characteristics of the transmission in different directions. The contact area can be increased through the layout of different planes and angles, and the absorption capacity of specific frequency vibrations can be enhanced, thereby more effectively isolating the vibration generated during the operation of the transmission, reducing the vibration energy transmitted from the transmission to the vehicle body, and improving ride comfort; and compared with a simple circular or single-shaped inner core, the polygonal structure can provide better torsion resistance and stability while maintaining sufficient elasticity, that is, when the inner core 4 is subjected to forces in different directions, the polygonal structure can distribute the load more evenly, reduce local stress concentration, and improve durability; and on each side of the polygonal inner core 4, the elastic characteristics of the transmission suspension 100 in different directions can be controlled by adjusting the material or design details, thereby achieving more precise control within the small movement range of the powertrain, which helps to maintain the correct alignment of the engine and transmission and reduce mechanical wear.

[0046] Therefore, by setting the transmission suspension 100, the connection and fastening strength at the inner core 4 can be enhanced, and the problem of following rotation when fastening the inner core 4 can be prevented, thereby improving the position stability of the inner core 4. The inner core 4 can also be enabled to fully isolate the vibrations generated by the transmission from different directions, preventing the transmission suspension 100 from being subjected to uneven force and causing local damage, thereby extending the service life.

[0047] According to some optional embodiments of the present invention, combined with Figure 5 and Figure 6As shown, the outer circumferential surface of the inner core 4 includes a top surface 42, a bottom surface 43, a first side surface 44 and a second side surface 45. The bottom surface 43 is arranged opposite to the top surface 42. The width of the bottom surface 43 is smaller than the width of the top surface 42. The first side surface 44 is respectively connected to the opposite sides of the top surface 42, and the first side surface 44 is perpendicular to the top surface 42. The second side surface 45 is respectively obliquely connected between the first side surface 44 and the bottom surface 43 on one side, and the main spring 3 is respectively connected to the second side surface 45.

[0048] Specifically, the top surface 42 and the bottom surface 43 are spaced apart from each other in the up-down direction, the first side surface 44 is respectively connected to the two lateral sides of the top surface 42, and the two ends of the second side surface 45 are respectively connected to the bottom surface 43 and the first side surface 44, so that the top surface 42, the bottom surface 43, the first side surface 44 and the second side surface 45 can construct the outer surface of the inner core 4, and the spacing between the laterally opposite second side surfaces 45 increases in the up-down direction (that is, vertically) as it moves away from the bottom surface 43, and the main spring 3 is connected to the second side surface 45, so that a force transmission path can be formed for the inner core 4 after being subjected to the dynamic load of the transmission. Since the force transmission path is inclined, the external force can be decomposed into component forces along the lateral and vertical directions (that is, the up-down directions), so as to better match the vibration direction generated by the transmission under different working conditions, and then more effectively absorb and disperse the vibration energy, reduce the vibration energy transmitted from the transmission to the vehicle, and improve ride comfort.

[0049] In addition, the main spring 3 is connected to the second side surface 45 which is inclined relative to each other, which is also conducive to the main spring 3 and the inner core 4 being able to construct a shape with a stable structure. Through such a design, the ability of the inner core 4 to resist twisting and bending can be effectively enhanced without significantly increasing the use of materials or weight, thereby improving the structural durability of the transmission suspension 100.

[0050] According to some optional embodiments of the present invention, combined with Figure 7 and Figure 8 As shown, the outer frame 2 is provided with a protruding portion 21 protruding inwardly, and the main spring 3 is provided with a recessed portion 31 recessed inwardly, and the protruding portion 21 and the recessed portion 31 are limitedly matched.

[0051] Furthermore, a limiting fitting relationship is established between the raised portion 21 of the exoskeleton 2 and the recessed portion 31 of the main spring 3, thereby increasing the contact area between the exoskeleton 2 and the main spring 3, thereby making the connection adhesion between the exoskeleton 2 and the main spring 3 greater, thereby improving the connection strength between the exoskeleton 2 and the main spring 3; the limiting effect of each other can also be enhanced through the concave-convex fitting, thereby enhancing the anti-falling effect of the main spring 3, thereby improving the position stability between the two.

[0052] According to some optional embodiments of the present invention, combined with Figure 3 and Figure 4As shown, the main spring 3 is provided with first limiting portions 32 protruding inward on both lateral sides, and the first limiting portions 32 are used to cooperate with the inner core 4 at the lateral upper limit of the main spring 3; the main spring 3 is provided with second limiting portions 33 protruding inward on both vertical sides, and the second limiting portions 33 are used to cooperate with the inner core 4 at the vertical upper limit of the main spring 3.

[0053] Specifically, since the main spring 3 is made of elastic material and can undergo elastic deformation, the main spring 3 is respectively provided with a first limiting portion 32 and a second limiting portion 33 corresponding to the outer surface of the inner core 4 in the lateral and vertical directions. When the inner core 4 is subjected to the lateral force from the transmission, the inner core 4 is laterally displaced. At this time, the first limiting portion 32 can buffer and limit the inner core 4 to prevent the inner core 4 from moving too much in the lateral direction and causing the risk of severe deformation of the inner core 4; when the inner core 4 is subjected to the vertical force from the transmission, the inner core 4 is vertically displaced. At this time, the first limiting portion 32 can buffer and limit the inner core 4 to prevent the inner core 4 from moving too much in the vertical direction and causing the risk of severe deformation of the inner core 4, thereby improving the protection of the inner core 4 and further extending the service life of the inner core 4.

[0054] Optionally, a plurality of spaced-apart protrusions 35 are formed on the side of the main spring 3 facing away from the inner core 4, so that the pressure between the main spring 3 and the transmission can be increased, thereby increasing the relative position stability between the main spring 3 and the transmission.

[0055] According to some optional embodiments of the present invention, combined with Figure 2 and Fig. 9 As shown, the transmission suspension 100 further includes a limiting pad 6 , which is disposed between the inner core 4 and the limiting member 5 , and the limiting pad 6 is provided with an avoidance hole 61 , and the inner core 4 is penetrated with the avoidance hole 61 .

[0056] Furthermore, combined with Figure 2 and Fig. 9 As shown, a limiting pad 6 is provided between the inner core 4 and the limiting member 5 along the axial direction of the outer frame 2, so that the weight and spatial mode of the inner core 4 can be further increased, thereby improving the structural strength and bending and torsional rigidity of the inner core 4, and can also generate additional friction after the fastener is fastened, thereby preventing the fastener from being easily loosened in a vibration environment. In addition, the avoidance hole 61 on the limiting pad 6 can provide an avoidance space for the inner core 4 to pass through the limiting pad 6, so that the inner core 4 can be smoothly connected to the limiting member 5.

[0057] Specifically, combined Figure 5 and Figure 6 As shown, the inner core 4 is provided with a fixing hole 46, and the stopper 5 has a fixing portion 52 protruding toward one side of the inner core 4, the fixing portion 52 extends into the fixing hole 46, and the fixing portion 52 contacts and cooperates with the inner wall of the fixing hole 46. For example, the fixing hole 46 can be rectangular or square, etc., but is not limited thereto.

[0058] It can be understood that the fixing portion 52 on the limit member 5 is in contact with the inner wall of the fixing hole 46 on the inner core 4, so that the limit member 5 and the inner core 4 can form a pre-positioning effect for installation, which is beneficial for the limit member 5 and the inner core 4 to find the relative position in advance, thereby improving the assembly accuracy and convenience.

[0059] Furthermore, combined with Fig. 9 As shown, the limiting member 5 includes a limiting plate 53 and a flange 54, the limiting pad 6 is arranged on the limiting plate 53, the flange 54 is bent and connected to the outer peripheral edge of the limiting plate 53, and the flange 54 extends toward a side away from the inner core 4, and the flange 54 is provided with a harness hole 541.

[0060] That is, the flange 54 changes the extension direction of the limit plate 53, so that the spatial mode of the limit plate 53 can be increased, thereby improving the bending and torsional rigidity of the limiter 5; and the flange 54 extends axially toward the side away from the inner core 4, so that the flange 54 can be prevented from forming structural interference with the bracket 1, thereby improving the rationality of its layout. Among them, the flange 54 is provided with a harness hole 541 that allows the harness to pass through. Such an arrangement can restrict the direction of the harness, thereby improving the neatness of the harness layout.

[0061] Specifically, combined Figure 2 As shown, the limiting pad 6 is provided with a plurality of limiting ribs 62 protruding toward the main spring 3, and the plurality of limiting ribs 62 are distributed on opposite sides of the inner core 4. It can be understood that the limiting pad 6 is provided with a plurality of protruding limiting ribs 62 at intervals on one side facing the main spring 3, and the plurality of limiting ribs 62 are distributed vertically on the upper and lower sides, so that the structural strength and bending and torsional rigidity can be effectively improved without significantly increasing the thickness and weight of the limiting pad 6, and the stress distribution inside the limiting pad 6 can be improved to avoid stress concentration, reduce cracking or deformation caused by local overload, and can also disperse these loads when subjected to uniform loads or point loads, reduce the flexural deformation of the limiting pad 6, ensure its flatness and working accuracy, thereby improving its structural reliability and practicality. In addition, the limiting ribs 62 can be in contact with the main spring 3 in advance, so that the contact area between the limiting pad 6 and the main spring 3 will be reduced, thereby increasing the pressure between the limiting pad 6 and the main spring 3 when the fastening force of the fastener is constant, and then increasing the relative position stability between the two.

[0062] According to some optional embodiments of the present invention, combined with Figure 7As shown, a plurality of weight-reducing holes 22 are provided on the outer circumference of the exoskeleton 2; and a positioning notch 23 is provided at one axial end of the exoskeleton 2. In other words, the exoskeleton 2 can reduce the weight of the exoskeleton 2 by designing a plurality of weight-reducing holes 22 while ensuring its own structural strength, thereby saving consumables of the exoskeleton 2, and further improving its lightweight design effect and economy. Among them, a positioning notch 23 is provided at one axial end of the exoskeleton 2, so that the exoskeleton 2 can be accurately assembled in the first mounting cavity 11 of the bracket 1, thereby achieving a foolproof effect.

[0063] The vehicle according to the embodiment of the second aspect of the utility model includes the transmission suspension 100 of the above embodiment. The vehicle with the transmission suspension 100 can effectively isolate and buffer the vibration energy on the transmission, thereby improving the driving comfort of the driver and passengers, and further improving the market competitiveness of the vehicle.
