[0002] The commonly used transmission control mechanism in existing vehicles is the flexible shaft type transmission control mechanism. Currently, the commonly used flexible shaft is fixed to the stabilizer bar by a bracket. Since one end of the flexible shaft is connected to the transmission control mechanism in the cab, and the other end passes through the bracket and is connected to the gearbox on the vehicle frame, when the cab is tilted, the flexible shaft is prone to causing the bracket to move relative to the stabilizer bar, thereby increasing the risk of interference between the flexible shaft and surrounding components. Utility Model Content

[0003] The main objective of this invention is to propose a suspension system and vehicle that improves the assembly stability of the flexible shaft retainer on the suspension system, thereby improving the limiting effect on the flexible shaft.

[0004] To achieve the above objectives, the suspension system proposed in this utility model includes:

[0005] Swing arm assembly;

[0006] The stabilizer bar assembly has its end fixedly connected to the swing arm assembly;

[0007] The flexible shaft fixing bracket has one end connected to the connection between the swing arm assembly and the stabilizer rod assembly, and the other end extends away from the swing arm assembly and is fixed with a pipe clamp. A limiting channel for the flexible shaft to pass through is formed between the pipe clamp and the flexible shaft fixing bracket.

[0008] In one embodiment, the swing arm assembly includes a swing arm, and the stabilizer assembly includes a stabilizer and a connecting seat connected to the stabilizer. The connecting seat is connected to the end of the swing arm, and the flexible shaft fixing bracket is fixed on the side opposite to the swing arm.

[0009] In one embodiment, the flexible shaft fixing bracket includes a first connecting bracket and a second connecting bracket. The first connecting bracket is connected to the connecting seat. One end of the second connecting bracket is connected to the first connecting bracket, and the other end extends toward the stabilizing rod. The tube clamp is connected to the side of the second connecting bracket away from the stabilizing rod.

[0010] In one embodiment, the connecting seat has a connecting hole, the swing arm has a first mating hole that engages with the connecting hole, and the first connecting bracket has a second mating hole that engages with the connecting hole. The first mating hole, the connecting hole, and the second mating hole are fixed together by fasteners.

[0011] In one embodiment, two connecting holes are spaced apart, and the first connecting frame includes two sub-connecting frames spaced apart, with the second mating hole provided on each sub-connecting frame;

[0012] And / or, the connecting seat is provided with a limiting slot adapted to the first connecting frame.

[0013] In one embodiment, the flexible shaft fixing frame further includes a flange corresponding to the limiting channel, one end of which is connected to the second connecting frame, and the other end is bent in a direction away from the limiting channel.

[0014] In one embodiment, the flange is connected to the upper edge of the second connecting frame;

[0015] And / or, at least one of the upper and lower edges of the second connecting frame is provided with a clearance notch, the clearance notch being disposed away from the first connecting frame.

[0016] In one embodiment, the first connecting frame and the second connecting frame are staggered in the stacking direction of the connecting seat and the flexible shaft fixing frame;

[0017] An adapter frame is bent and connected between the first connecting frame and the second connecting frame.

[0018] In one embodiment, the second connecting bracket has two mounting holes for connecting the two ends of the pipe clamp, and the two mounting holes are staggered vertically.

[0019] This utility model also proposes a vehicle that includes the suspension system described above;

[0020] Frame;

[0021] The cab is connected to the frame via the swing arm assembly of the suspension system, and the transmission control mechanism inside the cab is connected to the gearbox on the frame via the flexible shaft.

[0022] In the technical solution of this utility model, the flexible shaft fixing bracket is installed at the connection between the swing arm assembly and the stabilizer bar assembly. Compared with the flexible shaft fixing bracket being installed on the stabilizer bar assembly, this effectively improves the assembly stability of the flexible shaft fixing bracket on the suspension system, reduces the risk of the flexible shaft fixing bracket rotating relative to the stabilizer bar assembly, and improves the compactness of the suspension system. Furthermore, a tube clamp is fixed at one end of the flexible shaft fixing bracket extending away from the swing arm assembly, forming a limiting channel for the flexible shaft to pass through. This allows the flexible shaft to be kept away from the swing arm assembly, and the limiting channel reliably supports and constrains the direction of the flexible shaft, thereby reliably ensuring that the flexible shaft follows a regular direction when the vehicle is in motion and when the cab is tilted, reducing the possibility of wear caused by interference between the flexible shaft and surrounding components, and reducing the risk of flexible shaft failure.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0037] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture.

Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0039] The commonly used transmission control mechanism in existing vehicles is the flexible shaft type transmission control mechanism. Currently, the commonly used flexible shaft is fixed to the stabilizer bar by a bracket. Since one end of the flexible shaft is connected to the transmission control mechanism in the cab, and the other end passes through the bracket and is connected to the gearbox on the vehicle frame, when the cab is tilted, the flexible shaft is prone to causing the bracket to move relative to the stabilizer bar, thereby increasing the risk of interference between the flexible shaft and surrounding components.

[0040] To solve this technical problem, this utility model proposes a suspension system that is applied to a vehicle, specifically a truck or freight vehicle.

[0041] Please see Figures 1 to 6In one embodiment of this utility model, the suspension system includes a swing arm assembly 10, a stabilizer bar assembly 20, and a flexible shaft mounting bracket 30. The end of the stabilizer bar assembly 20 is fixedly connected to the swing arm assembly 10. One end of the flexible shaft mounting bracket 30 is connected to the connection between the swing arm assembly 10 and the stabilizer bar assembly 20, and the other end extends away from the swing arm assembly 10 and is fixed with a pipe clamp 40. A limiting channel 41 for the flexible shaft 60 to pass through is formed between the pipe clamp 40 and the flexible shaft mounting bracket 30. This reliably ensures that the flexible shaft 60 follows a regular path when the vehicle is in motion and when the cab is tilted, and does not interfere with surrounding components, thereby reducing the risk of functional failure of the flexible shaft 60.

[0042] In the technical solution of this utility model, the flexible shaft fixing bracket 30 is installed at the connection between the swing arm assembly 10 and the stabilizer bar assembly 20. Compared with the flexible shaft fixing bracket 30 being installed on the stabilizer bar assembly 20, this effectively improves the assembly stability of the flexible shaft fixing bracket 30 on the suspension system, reduces the risk of the flexible shaft fixing bracket 30 rotating relative to the stabilizer bar assembly 20, and improves the compactness of the suspension system. Furthermore, a pipe clamp 40 is fixed at one end of the flexible shaft fixing bracket 30 extending away from the swing arm assembly 10, forming a limiting channel 41 for the flexible shaft 60 to pass through. This allows the flexible shaft 60 to move away from the swing arm assembly 10, and the limiting channel 41 reliably supports and constrains the direction of the flexible shaft 60, thereby reliably ensuring that the flexible shaft 60 follows a regular direction when the vehicle is in motion and when the cab is tilted, reducing the possibility of the flexible shaft 60 interfering with surrounding components and causing wear, and reducing the risk of the flexible shaft 60 failing.

[0043] It should be noted that there are two control arm assemblies 10, and the two control arm assemblies 10 are connected by a stabilizer bar assembly 20. The lower ends of both control arm assemblies 10 are used to connect to the vehicle frame to fix the suspension system to the vehicle frame. The control arm assembly 10 can also be used to connect to the vehicle's cab, where a gear shifting mechanism is provided. A gearbox is provided on the vehicle frame. The gear shifting mechanism is connected to the gearbox via a flexible shaft 60 to realize the vehicle's gear shifting operation. When the cab is tilted, the flexible shaft fixing bracket 30 is installed at the connection between the swing arm assembly 10 and the stabilizer bar assembly 20. The flexible shaft fixing bracket 30, the swing arm assembly 10, and the stabilizer bar assembly 20 are relatively fixed. The flexible shaft 60 moves within the limiting channel 41 as the cab tilts. The flexible shaft fixing bracket 30 cannot rotate relative to the stabilizer bar assembly 20. That is, before and after the cab tilts and during vehicle travel, the direction of the flexible shaft 60 is reliably constrained by the limiting channel 41. Combined with the setting of the limiting channel 41 being far away from the swing arm assembly 10, the risk of interference between the flexible shaft 60 and surrounding components is further reduced, the possibility of wear on the flexible shaft 60 is reduced, and the reliability and service life of the flexible shaft 60 are improved.

[0044] Optionally, in an embodiment of this utility model, the swing arm assembly 10 includes a swing arm 11, and the stabilizer rod assembly 20 includes a stabilizer rod 21 and a connecting seat 22 connected to the stabilizer rod 21. The connecting seat 22 is connected to the end of the swing arm 11, and the flexible shaft fixing frame 30 is fixed on the side opposite to the swing arm 11. That is, the connecting seat 22 and the flexible shaft fixing frame 30 are stacked sequentially on the end of the swing arm 11, which not only allows the swing arm 11, the stabilizer rod 21, and the flexible shaft fixing frame 30 to be arranged compactly, reducing the space occupied, but also facilitates the quick fixing of the swing arm 11, the stabilizer rod 21, and the flexible shaft fixing frame 30, improving assembly efficiency. However, in other embodiments, the flexible shaft fixing frame 30 is installed on the swing arm 11; or the flexible shaft fixing frame 30 is sandwiched between the swing arm 11 and the connecting seat 22.

[0045] The swing arm 11 has a support platform protruding from its end. The connecting seat 22 can be placed on the support platform to facilitate the initial positioning and connection between the connecting seat 22 and the swing arm 11, thereby improving assembly efficiency. Specifically, the connecting seat 22 has a first limiting hole 24, which can be located on the extension line of the stabilizer 21 or offset from the extension line of the stabilizer 21. In this case, the swing arm 11 has a second limiting hole 24 that mates with the first limiting hole 24. The second limiting hole 24 is a threaded hole. Screws are passed through the first limiting hole 24 and the second limiting hole 24 in sequence and locked in the second limiting hole 24 to complete the positioning and connection of the connecting seat 22 on the swing arm 11. The support platform can also support the flexible shaft fixing frame 30, which facilitates the positioning and connection between the connecting seat 22 and the flexible shaft fixing frame 30, further improving assembly efficiency. Of course, in other embodiments, the end of the swing arm 11 is not provided with a support platform; or the support platform only supports the connecting seat 22.

[0046] The stabilizer bar 21 is provided with a connecting seat 22, which is connected to the end of the stabilizer bar 21, or the connecting seat 22 passes through the stabilizer bar 21. In this case, the end of the stabilizer bar 21 passing through the connecting seat 22 can be used to connect to the tilting bracket, which is used to connect to the cab.

[0047] Please see Figures 1 to 3 In an embodiment of this utility model, the flexible shaft fixing bracket 30 includes a first connecting bracket 31 and a second connecting bracket 32. The first connecting bracket 31 is connected to the connecting seat 22. One end of the second connecting bracket 32 ​​is connected to the first connecting bracket 31, and the other end extends toward the stabilizing rod 21. The pipe clamp 40 is connected to the side of the second connecting bracket 32 ​​away from the stabilizing rod 21. This arrangement makes reasonable use of the assembly space around the stabilizing rod 21 to meet the wiring requirements of the flexible shaft 60, reduces the possibility of interference between the flexible shaft 60 and the swing arm 11, and thus improves the reliability and service life of the flexible shaft 60.

[0048] The connection methods of the first connecting frame 31 and the second connecting frame 32 include, but are not limited to, integral molding and welding, to ensure the connection and load-bearing capacity of the flexible shaft fixing frame 30; the connection between the first connecting frame 31 and the connecting seat 22 and / or the swing arm 11 includes, but is not limited to, screw connection, snap connection, and pin connection; the connection methods between the second connecting frame 32 and the pipe clamp 40 include, but are not limited to, integral molding, screw connection, and snap connection. However, in other embodiments, the other end of the second connecting frame 32 extends away from the connecting seat 22.

[0049] Please see Figures 1 to 4 In one embodiment of this utility model, the connecting seat 22 has a connecting hole 23, the swing arm 11 has a first mating hole that engages with the connecting hole 23, and the first connecting frame 31 has a second mating hole 311 that engages with the connecting hole 23. The first mating hole, the connecting hole 23, and the second mating hole 311 are fixed together by fasteners 50, which reliably simplifies the structure of the suspension system, reduces the number of parts, and thus effectively saves assembly costs and improves assembly efficiency. However, in other embodiments, the swing arm 11 is provided with a positioning post, and the connecting hole 23 of the connecting seat 22 and the second mating hole 311 of the first connecting frame 31 are sequentially inserted into the positioning post and fixedly connected to the positioning post by screws or nuts.

[0050] Optionally, in an embodiment of this utility model, two connecting holes 23 are spaced apart. The first connecting frame 31 includes two spaced-apart sub-connecting frames 312, each sub-connecting frame 312 having a second mating hole 311. This improves the connection stability between the first connecting frame 31 and the connecting seat 22. Furthermore, the spaced arrangement of the two sub-connecting frames 312 helps reduce material usage, thus reducing the weight of the first connecting frame 31 and lowering processing costs. The first limiting hole 24 is located between the two connecting holes 23, or at least one connecting hole 23 is configured as the first limiting hole 24. However, in other embodiments, the first connecting frame 31 is a plate, and the plate has two second mating holes 311.

[0051] Please see Figure 1 and Figure 6 In an embodiment of this utility model, the connecting seat 22 is provided with a limiting slot 25 adapted to the first connecting frame 31, so as to realize the positioning of the first connecting frame 31 on the connecting seat 22, which facilitates the alignment efficiency of the connecting hole 23 and the second mating hole 311. Taking the first connecting frame 31 as an example, which includes two sub-connecting frames 312 arranged at intervals, the limiting slot 25 is provided with two corresponding sub-connecting frames 312, and the sub-connecting frames 312 are locked in the limiting slot 25.

[0052] Please see Figures 1 to 4In an embodiment of this utility model, the flexible shaft fixing bracket 30 further includes a flange 33 corresponding to the limiting channel 41. One end of the flange 33 is connected to the second connecting bracket 32, and the other end is bent in a direction away from the limiting channel 41. On the one hand, the flange 33 strengthens the structural strength of the second connecting bracket 32. On the other hand, the flange 33 is bent in a direction away from the limiting channel 41 and formed on the edge of the second connecting bracket 32, which can make the edge of the second connecting bracket 32 ​​smoother, reduce the risk of wear caused by edge interference between the flexible shaft 60 and the second connecting bracket 32, and also guide the direction of the flexible shaft 60 to a certain extent.

[0053] Specifically, in the embodiments of this utility model, the flange 33 is connected to the upper edge of the second connecting frame 32, so that when the cab is tilted or the vehicle is in motion, the flange 33 reliably fits and supports the flexible shaft 60, reducing wear and excessive bending of the flexible shaft 60, which helps to ensure the normal use of the flexible shaft 60 and improve the reliability and service life of the flexible shaft 60.

[0054] Please see Figure 4 In an embodiment of this utility model, at least one of the upper and lower edges of the second connecting frame 32 is provided with an avoidance notch 322. The avoidance notch 322 is located away from the first connecting frame 31, that is, the avoidance notch 322 is close to the limiting channel 41. On the one hand, it reliably provides bendable space to the flexible shaft 60, reducing the risk of interference between the second connecting frame 32 and the flexible shaft 60 due to the excessive size of the second connecting frame 32. On the other hand, it helps to reduce material usage, lighten the weight of the second connecting frame 32, and reduce processing costs. The upper and lower edges are specifically arranged along the vertical direction of the vehicle body.

[0055] Please see Figures 4 to 5 In an embodiment of this utility model, in the stacking direction of the connecting seat 22 and the flexible shaft fixing frame 30, the first connecting frame 31 and the second connecting frame 32 are staggered; a transition frame 34 is bent and connected between the first connecting frame 31 and the second connecting frame 32. It can be understood that the first connecting frame 31 is connected to the second connecting frame 32 through the transition frame 34. The first connecting frame 31 and the second connecting frame 32 can be arranged parallel to each other or at an angle. This reliably adapts to the positional difference between the mounting plane on the connecting seat 22 connected to the flexible shaft fixing frame 30 and the outer peripheral surface of the stabilizer bar 21. At the same time, it ensures that the second connecting frame 32 is spaced apart from the stabilizer bar 21 so as to avoid the second connecting frame 32 affecting the anti-tilting function of the stabilizer bar 21.

[0056] Please see Figure 2 and Figure 4In this embodiment of the present invention, the second connecting frame 32 is provided with two mounting holes 321 connecting the two ends of the pipe clamp 40. The two mounting holes 321 are staggered vertically. At this time, the pipe clamp 40 is offset in the vertical direction, and the extension direction of the limiting channel 41 formed there is an offset angle between the vertical direction and the vertical direction. This facilitates the adaptation to the position layout of the transmission control mechanism and the flexible shaft fixing frame 30 in the cab, reduces the possibility of the flexible shaft 60 interfering with the pipe clamp 40 when it bends in the limiting channel 41, and causes wear, and effectively improves the reliability and service life of the flexible shaft 60.

[0057] This utility model also proposes a vehicle including a suspension system. The specific structure of the suspension system is as described in the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The vehicle also includes a frame and a cab. The cab is connected to the frame via the swing arm assembly 10 of the suspension system. The gear shift mechanism in the cab is connected to the gearbox on the frame via the flexible shaft 60.

[0058] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
