[0002] With the continuous development of urban and transportation planning, more and more urban areas or communities are difficult to be effectively covered by public transportation. The micro-circulation bus system has become an important part of the urban public transportation system. Micro-circulation vehicles are small in size and fast in speed, and are suitable for short bus routes.

[0003] In related technologies, traditional larger vehicle models usually use traditional leaf spring suspensions. The vehicle floor is far from the ground, so there is sufficient space in the vehicle. Even if the suspension occupies a large space, it can be installed. However, for micro-circulation vehicle models, the vehicle floor is lower to the ground, and the space in the vehicle is compact and narrow, which is not suitable for traditional leaf spring suspensions that occupy a large space. Even if it is barely installed, abnormal noises are likely to occur, affecting the layout of other components of the vehicle and the ride comfort. Utility Model Content

[0004] An object of the present disclosure is to provide a suspension that can effectively utilize space in a car and avoid interference between components in the suspension.

[0027] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0028] In this disclosure, unless otherwise stated, directional words such as "upper, lower, high, low, top, bottom" generally refer to the orientation of the corresponding component or structure in the direction of gravity. Figure 1The directions of the drawings shown. "Inside" and "outside" refer to the inside and outside of the corresponding component outlines. In addition, it should be noted that the terms used, such as "first" and "second", are used to distinguish one element from another and do not have sequentiality or importance. In addition, in the description with reference to the drawings, the same symbols in different drawings represent the same elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limiting the present disclosure.

[0029] For ease of understanding, please refer to the attached Figures 1 to 4 , the specific structure and working principle of the suspension disclosed in this invention are described in detail with reference to the embodiments.

[0030] The present disclosure relates to a suspension that can be applied to small and micro-cycle vehicles. Figure 1 and Figure 2 The suspension disclosed in the present invention is arranged between the axle 1 and the frame 2, and includes a leaf spring 4. The leaf spring 4 is connected to the axle 1 and can cooperate with the shock absorber 3 to achieve a shock absorbing and buffering effect. The suspension disclosed in the present invention also includes a stabilizer bar 5. Compared with the larger models in the related art, the stabilizer bar 5 can be connected to the bottom of the frame 2 and located in front of the axle 1 due to the larger space in the car, and the shock absorber 3 is located at a higher position above the frame 2. However, due to the smaller space in the micro-circulation model, the shock absorber 3 is difficult to be installed at a higher position above the frame 2, and the above connection method is not applicable. Therefore, the stabilizer bar 5 in the suspension disclosed in the present invention is connected between the leaf spring 4 and the frame 2, and is located above the axle 1 and the leaf spring 4, and behind the axle 1. This arrangement can effectively utilize the space above the frame 2, improve the space utilization efficiency, and also make the position originally below the frame 2 vacant for installing the shock absorber 3. The suspension disclosed herein further includes a connecting assembly 6, through which the stabilizer bar 5 can be connected to the leaf spring 4 and the frame 2 respectively, to ensure linkage between the stabilizer bar 5, the leaf spring 4 and the frame 2, thereby improving the stability of the vehicle during operation.

[0031] The suspension disclosed herein changes the position of the stabilizer bar 5 and sets the stabilizer bar 5 above the frame 2 and the leaf spring 4 and behind the axle 1, so that the position originally installed with the stabilizer bar 5 is vacated for installing the shock absorber 3, thereby being able to adapt to the smaller space in the micro-circulation vehicle model, ensuring that the suspension in the micro-circulation vehicle model does not occupy a large space, there will be no problem of interference between the stabilizer bar 5 and the shock absorber 3, and no abnormal noise will be generated during use, affecting the user experience.

[0032] In one embodiment of the present disclosure, see Figure 1 and Figure 2 The connecting assembly 6 includes a suspension rod clamp assembly 61 located at both ends of the stabilizing rod 5, and the suspension rod clamp assembly 61 can connect the two ends of the stabilizing rod 5 to the leaf spring 4 respectively. In some embodiments of the present disclosure, see Figure 3 and Figure 4 The suspension bar clamp assembly 61 includes a first suspension bar clamp 611 and a second suspension bar clamp 612, wherein the first suspension bar clamp 611 is a straight plate located on the relatively outer side of the vehicle frame 2, and the second suspension bar clamp 612 includes two first extensions 6121 extending in the vertical direction and a second extension 6122 extending in the oblique direction and adjacent to the two first extensions 6121. The first suspension bar clamp 611 is also spaced apart from the second suspension bar clamp 612 to form a space for placing the stabilizer bar 5. Connecting the stabilizer bar 5 to the leaf spring 4 through the suspension bar clamp assembly 61 can make the connection between the stabilizer bar 5 and the leaf spring 4 more stable. The lengths of the first suspension bar clamp 611 and the second suspension bar clamp 612 can also be adjusted according to actual conditions to flexibly change the height between the stabilizer bar 5 and the leaf spring 4 to accommodate more different micro-circulation vehicle models.

[0033] In one embodiment of the present disclosure, see Figure 3 and Figure 4 The first suspension rod clamp 611 and the second suspension rod clamp 612 include a first end and a second end, and the width of the first suspension rod clamp 611 and the second suspension rod clamp 612 at the first end is smaller than the width at the second end. The second ends of the first suspension rod clamp 611 and the second suspension rod clamp 612 are used to connect the leaf spring 4, and the length of the connecting portion on the leaf spring 4 is relatively fixed to a standard length, so the width of the second end used for connection needs to be relatively fixed. If the width of the second end is changed, the design cost will increase. The stabilizing bar 5 is connected to the first end of the first suspension rod clamp 611 and the second suspension rod clamp 612. Through the second extension portion 6122 on the second suspension rod clamp 612, the length of the stabilizing bar 5 can be increased without changing the width of the second end of the first suspension rod clamp 611 and the second suspension rod clamp 612, while ensuring connection with the leaf spring 4, thereby improving the stabilizing effect of the stabilizing bar 5.

[0034] In one embodiment of the present disclosure, see Figure 3 and Figure 4 A connecting shaft 613 is provided at the second end of the first and second suspender plates 611, 612. The connecting shaft 613 sequentially passes through the first suspender plate 611, the leaf spring 4, and the second suspender plate 612, thereby connecting the suspender plate assembly 61 to the leaf spring 4. Connecting the suspender plate assembly 61 via the connecting shaft 613 allows the suspender plate assembly 61 and the stabilizer bar 5 connected thereto to rotate a certain angle relative to the leaf spring 4, thereby improving the stability of the connection between the stabilizer bar 5 and the leaf spring 4 provided by the suspender plate assembly 61 and further stabilizing the stabilizer bar 5.

[0035] In one embodiment of the present disclosure, see Figure 2 and Figure 3 A connecting ear 41 is provided on the leaf spring 4. The structure of the connecting ear 41 can be a circular single-layer structure, in which a connecting hole can be provided. The leaf spring 4 can be connected to the suspension rod clamp assembly 61 through the connecting ear 41. In this embodiment, the connecting ear 41 can be provided at the top end of the leaf spring 4 to cooperate with the second ends of the first suspension rod clamp 611 and the second suspension rod clamp 612, and the connecting ear 41 can also facilitate the connection of the connecting shaft 613. Of course, in other embodiments, the portion of the connecting assembly 6 that connects the stabilizer bar 5 to the leaf spring 4 can also have other structures, which can be determined according to actual conditions, and the present disclosure does not limit this.

[0036] In one embodiment of the present disclosure, see Figure 2 and Figure 3 The connecting assembly 6 further includes a bushing assembly 62, which is located in the middle section of the stabilizer bar 5. The bushing assembly 62 can connect the stabilizer bar 5 to the vehicle frame 2. In this embodiment, the bushing assembly 62 can include a clamp sleeved on the middle section of the stabilizer bar 5, with a bushing disposed in the clamp. The stabilizer bar 5 is connected via the clamp, and the stabilizer bar 5 can rotate in the clamp to stabilize the leaf spring 4. Of course, in other embodiments, the bushing assembly 62 can also have other structures, as long as it can connect the stabilizer bar 5 to the vehicle frame 2. The specific structure can be determined according to actual conditions, and this disclosure does not impose any restrictions on this.

[0037] In one embodiment of the present disclosure, see Figure 2 and Figure 3 The leaf spring 4 includes a plurality of spring leaves 42, with noise reduction sheets disposed between adjacent spring leaves 42. By disposing noise reduction sheets 43 between adjacent spring leaves 42 of the leaf spring 4, the noise generated by friction or collision between the spring leaves 42 during vehicle operation can be reduced, thereby improving the user experience and reducing damage to the spring leaves 42 to a certain extent.

[0038] In one embodiment of the present disclosure, see Figure 1 and Figure 2The suspension disclosed herein also includes a shock absorber 3. In the related art, the shock absorber 3 of a large vehicle has a larger space in the vehicle, so the stabilizer bar 5 is arranged in front of the frame 2, and the shock absorber 3 is arranged behind the frame 2. However, due to the smaller space in the micro-circulation vehicle, it is difficult to arrange the longer shock absorber 3 vertically in front of the frame 2. Therefore, the suspension disclosed herein arranges the stabilizer bar 5 between the leaf spring 4 and the frame 2, above the axle 1 and the leaf spring 4, and behind the axle 1, so as to provide space for the installation of the shock absorber 3. During installation, due to the longer length of the shock absorber 3, the shock absorber 3 needs to be arranged at an angle to reduce the vertical height of the shock absorber 3, so that the shock absorber 3 can be installed smoothly in a smaller space.

[0039] In a second aspect of the present disclosure, a car is provided, comprising an axle 1, a frame 2, and the suspension described in the above embodiment, wherein a stabilizer bar 5 in the suspension is located between the leaf spring 4 and the frame 2, above the axle 1 and the leaf spring 4, and also behind the axle 1, and is connected to the leaf spring 4 and the frame 2 via a connecting assembly 6. The specific connection process can be referred to the description in the above suspension embodiment, which will not be repeated here. The car of the present disclosure can be a micro-circulation vehicle model. Since the space in the micro-circulation vehicle model is relatively small, the stabilizer bar 5 in the suspension is connected between the leaf spring 4 and the frame 2, and is located above the axle 1 and the leaf spring 4, and behind the axle 1, which can effectively utilize the space in the car and provide space for the installation of the shock absorber 3, so as to ensure that the suspension in the micro-circulation vehicle model does not occupy a large space, does not cause interference between the stabilizer bar 5 and the shock absorber 3, and does not produce abnormal noise during use, affecting the user's experience.

[0040] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0041] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0042] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
