Description

Technical Field

[0001] This utility model relates to the field of automotive suspension technology, specifically to a balance beam connection device for automotive suspension. Background Technology

[0002] In existing automotive suspension systems, the equalizer beam connection device often suffers from unreasonable structural design: traditional equalizer beams mostly adopt a split splicing structure, which is not rigid enough. When the vehicle is under heavy load or driving on complex road conditions, it is prone to deformation due to stress concentration, which affects the load balance effect and shortens the service life. The connection method between the support arm and the axle and equalizer beam in the connection component is relatively complicated, and it is often spliced ​​with multiple connectors. Not only are the assembly steps cumbersome, but the fit clearance is also prone to insufficient guiding accuracy, making the axle movement trajectory unstable, which aggravates tire wear and driving vibration. Utility Model Content

[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0016] Example 1: As Figures 1-3 ,include: The equalizing beam body 100 is an integral structure, and both ends of the equalizing beam body 100 are fixedly connected to the connecting blocks 120. The connecting assembly includes an upper support arm 200 and a lower support arm 220, which are rotatably connected to the axle 250. The inner wall of the axle 250 is rotatably connected to the wheel 260 via bearings.

[0017] The specific application scenario of this embodiment is as follows: The integrated structure ensures overall rigidity, and the connecting blocks 120 at both ends provide an installation base for the connecting components. The upper support arm 200 and the lower support arm 220 form a triangular stable support structure, with one end cooperating with the connecting block 120 and the other end jointly rotating to connect to the axle 250, achieving flexible suspension of the axle 250. The wheel disc 260 is rotatably connected to the inner wall of the axle 250 through bearings, ensuring that the wheels can rotate freely. When the vehicle is in motion, the equalizing beam body 100 bears part of the vehicle body load and transmits it to the axle 250. The upper support arm 200 and the lower support arm 220 work together to restrict the lateral and longitudinal displacement of the axle 250, while allowing the axle to sway slightly with road surface undulations, achieving basic load-bearing and motion guidance functions.

[0018] Example 2: Figures 3-5 and Figure 2 The top and bottom outer walls of the equalizing beam body 100 are fixedly installed with reinforcing plates 110. The connecting block 120 is perpendicular to the equalizing beam body 100. The inner wall of the connecting block 120 is provided with a through hole 121 for arranging the drive shaft. The left and right outer walls of the connecting block 120 are fixedly connected with rotating shafts. The rotating shafts are rotatably connected to the upper support arm 200 and the lower support arm 220.

[0019] The specific application scenario of this embodiment is as follows: The equalizing beam body 100 further enhances its bending and torsional strength through the top and bottom reinforcing plates 110, avoiding deformation under large loads. The connecting block 120 is perpendicularly distributed to the equalizing beam body 100, forming a "T"-shaped structure to optimize the force transmission path. The through hole 121 of the connecting block 120 is used to pass through the drive shaft, ensuring that the drive shaft can rotate synchronously with the wheel without interfering with the suspension movement. The rotating shafts on its left and right sides are rotatably connected to the upper support arm 200 and the lower support arm 220, allowing the upper support arm 200 and the lower support arm 220 to swing flexibly around the rotating shaft. When one side of the vehicle's wheel encounters a bump, the rotating shaft allows the upper support arm 200 and the lower support arm 220 to rotate relative to the connecting block, causing the axle 250 to tilt adaptively. The equalizing beam body 100 balances the load on the left and right sides through the rigid structure, while the drive shaft stably transmits power through the through hole 121, realizing the coordinated work of "load bearing-guidance-power transmission".

[0020] Example 3: Figures 3-5 The upper support arm 200 has a triangular structure. The end of the upper support arm 200 away from the balance beam body 100 is provided with a cross arm 210. The cross arm 210 is connected to the outer wall of the axle 250 by a pivot pin. The lower support arm 220 is fixedly connected to the support plate 230 at the end near the axle 250. The top outer wall of the support plate 230 is connected to the outer wall of the axle 250 by a pivot pin. Rotating blocks 240 are fixedly installed on the top outer wall of the support plate 230 and the outer wall of the connecting block 120. There are two sets of rotating blocks 240. The rotating blocks 240 are used to rotate and connect the vibration damping rod 270. There are two sets of vibration damping rods 270 at the front and rear. The wheel is detachably fixedly installed on the outer wall of the wheel disc 260 by a screw 261.

[0021] The specific application scenario of this embodiment is as follows: The upper support arm 200 with a triangular structure enhances its resistance to deformation through geometric stability. Its end arm 210 is connected to the axle 250 via a pivot pin, limiting the vertical movement of the axle 250 and guiding its trajectory. The support plate 230 of the lower support arm 220 increases the contact area with the axle 250, strengthening the connection and preventing stress concentration on the axle. The rotating block 240 cooperates with the vibration damper 270. When the wheel is impacted by the road surface, the axle 250 drives the upper and lower support arms to swing. The vibration damper 270 absorbs the impact energy through the rotation of the rotating block 240, converting the vibration into internal energy and reducing the vibration transmitted to the vehicle body. The wheel disc 260 is detachably connected to the wheel via a screw 261, ensuring stable wheel installation and easy maintenance. The overall structure, through the synergy of "triangular support (guidance) + vibration damper 270 (damping) + rigid equalizing beam (load balancing)," achieves stable vehicle operation under complex road conditions, balancing load-bearing capacity, motion guidance accuracy, and ride comfort.

[0022] The working principle of this utility model is as follows: When used by those skilled in the art, the integrated balanced beam body 100 is used as the core load-bearing component. It is connected to the upper support arm 200 and the lower support arm 220 through the docking blocks 120 at both ends. The top and bottom reinforcing plates 110 enhance the overall rigidity to balance the left and right loads of the vehicle. The docking blocks 120 are rotatably engaged with the upper and lower support arms through the rotating shaft. The through hole 121 allows the drive shaft to pass through to realize power transmission. The triangular upper support arm 200 is connected to the axle 250 shaft pin through the cross arm 210 and the lower support arm 220 through the support plate 230, forming a stable support and guiding structure, limiting the displacement of the axle 250 and guiding it to make adaptive movements with the undulations of the road surface. At the same time, the vibration damping rod 270 connected to the rotating block 240 absorbs vibration energy when the axle is impacted. The wheel 260 fixes the wheel through the screw 261 and rotates relative to the axle with the help of the bearing. Finally, through the synergistic effect of each component, the comprehensive functions of load balance, power transmission, motion guidance and shock absorption are realized to ensure the vehicle's driving stability and structural reliability.
