Description

Technical Field

[0001] This utility model relates to the field of rear suspension assembly, and more particularly to a rear suspension assembly tooling. Background Technology

[0002] The rear suspension assembly serves to support the vehicle body and also bear and transmit the forces and torques exerted on the wheels by the road surface. Automotive rear suspension systems often employ a variety of advanced technologies, such as air springs, electronically controlled shock absorbers, and active stabilizer bars. The application of these technologies allows the automotive rear suspension to maintain its basic functions while also adjusting according to different driving conditions and driving needs, thereby providing drivers and passengers with a safer, more comfortable, and more enjoyable driving experience.

[0003] In existing technology, the chassis is transported to the suspension installation station via an assembly line. Since the rear suspension structure of commercial vehicles is large and heavy, in order to facilitate assembly, the suspension assembly is divided into two individual assemblies on the left and right sides and the axle. With the help of a hoist and multiple people working together, the leaf springs, shock absorbers and other components in the individual assemblies are connected to the frame respectively, and then the axle is installed. This method of assembly reduces labor intensity and improves assembly efficiency.

[0004] In the above technical solution, the rear suspension assembly is divided into two individual assemblies and assembled separately. However, due to positional and manufacturing errors in the mounting holes on both sides of the frame, and because most of the mounting holes are straight slots, the individual assemblies on both sides are installed separately, resulting in a large positional deviation. On the one hand, this causes uneven tire wear and vehicle drift, affecting the vehicle's handling and stability. On the other hand, when installing components such as the axle and the balance shaft between the two individual assemblies, the relevant components are subjected to bending and torsional forces due to the large installation errors, affecting the service life of the components. Utility Model Content

[0005] To address the significant installation error inherent in the prior art where the rear suspension assembly is mounted as a separate unit on both sides, this invention provides a rear suspension assembly fixture that enables the rear suspension assembly to be installed as a single unit onto the chassis, thus avoiding the problem of large installation errors at both ends of the rear suspension assembly affecting its use.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a rear suspension assembly tooling, including a base, and further including: a support assembly, wherein two support assemblies are provided, the two support assemblies are respectively movably disposed at both ends of the base, and the two support assemblies move in opposite directions; a clamping assembly, wherein the clamping assembly is disposed on the top of the support assembly, the clamping assembly is used to clamp the rear suspension assembly, the clamping assembly includes a mounting base, and the mounting base is rotatably provided with claw assemblies on both sides, the two claw assemblies rotating in opposite directions.

[0007] This invention, through the cooperation of support components and clamping components, can support the pre-assembled rear suspension as a whole. Compared with the prior art, it can improve the installation accuracy of the structural components at both ends of the suspension assembly and avoid tire wear and deviation.

[0008] Furthermore, the support assembly includes a movable base and a movable drive component. Two movable bases are movably and symmetrically arranged on the base. The movable bases of both support assemblies are connected to the movable drive component. The movable drive component is disposed on the base. A support plate is disposed on the movable base, and the mounting base is disposed on the support plate.

[0009] This utility model, by symmetrically arranging two movable seats and connecting them to the same movable drive component, ensures that the movable seats at both ends remain symmetrical about the center of the base after movement, thus meeting the support requirements of rear suspension assemblies of different sizes and ensuring the flexible use of this tooling.

[0010] Furthermore, the moving drive component is a moving motor, which is mounted on the base and connected to a driving bevel gear. A guide rod and a lead screw are provided through the moving base. The guide rod is mounted on the base, and a driven bevel gear is provided at the end of the lead screw. The driven bevel gear meshes with the driving bevel gear.

[0011] Furthermore, the movable seat is provided with a mounting groove, the support plate is mounted on the movable seat via a rotating shaft, and a torsion spring is provided between the mounting groove and the support plate.

[0012] This invention, by incorporating a torsion spring, enables the support plate to automatically rotate to a position parallel to the base after the rear suspension assembly is no longer under load, facilitating transportation and storage.

[0013] Furthermore, the gripper assembly includes a rotating frame and a clamping drive component. The rotating frame is provided with a clamping plate. The rotating frame is rotatably mounted in the mounting base via a transmission shaft. The mounting base has a U-shaped structure, and both transmission shafts are connected to the clamping drive component.

[0014] Furthermore, the clamping drive component is a clamping motor, which is connected to a worm gear. The worm gear is vertically and rotatably mounted on the mounting base, and a worm wheel is mounted on the transmission shaft. Two worm wheels are respectively mounted on both sides of the worm gear.

[0015] Furthermore, the clamping plate is provided with a mounting cylinder, which is rotatably mounted on the support rod of the rotating frame.

[0016] This invention enables the clamping plate to be rotatably connected to the rotating frame, allowing the clamping plate to be finely adjusted according to the structure of the corresponding components of the suspension assembly during clamping, thereby increasing the contact area between the clamping plate and the corresponding components and enhancing the reliability of the support.

[0017] Furthermore, the mounting base is connected to the support plate via a damping shaft.

[0018] This invention enables the mounting base to rotate under external force when supported by a damping pivot, ensuring compatibility with rear suspension assemblies of different structures.

[0019] Furthermore, it also includes a movable lifting assembly, which includes a support housing disposed at the lower part of the base. A hydraulic cylinder is disposed inside the support housing, and the hydraulic cylinder is connected to a lifting plate. The lifting plate is disposed in the support housing in a lifting manner. A roller is disposed at the lower part of the lifting plate, and the roller can be fully inserted into the support housing. A brake is disposed on the roller.

[0020] This invention, by incorporating a movable lifting component, enables the base to move, lift, and lock, making it convenient to use.

[0021] Furthermore, it also includes a positioning component, which is disposed on the base and located between the two support components. The positioning component includes a positioning plate with a U-shaped structure, which can support the corresponding crossbeam of the chassis.

[0022] This invention, by setting a positioning component, can achieve the positioning of the suspension assembly and the frame in the front-rear direction through the crossbeam on the frame, thereby improving the installation efficiency of the suspension assembly and the frame.

[0023] As can be seen from the above technical solutions, this utility model has the following advantages:

[0024] This utility model provides a rear suspension assembly fixture. Through the cooperation of support components and clamping components, it can support the pre-assembled rear suspension as a whole. Compared with the prior art, it can improve the installation accuracy of the structural components at both ends of the suspension assembly and avoid tire wear and deviation. By setting a torsion spring, the support plate can automatically rotate to a position parallel to the base after not supporting the rear suspension assembly, which is convenient for transportation and storage. By rotatably connecting the clamping plate to the rotating frame, the clamping plate can be finely adjusted according to the structure of the corresponding components of the suspension assembly during clamping, increasing the contact area between the clamping plate and the corresponding components and enhancing the reliability of support. By setting a movable lifting component, the base can be moved, raised, lowered and locked, which is convenient to use. By setting a positioning component, the suspension assembly can be positioned in the front-rear direction of the frame through the crossbeam on the frame, improving the installation efficiency of the suspension assembly and the frame.

[0033] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent. Specific Implementation Method 1

[0035] like Figure 1As shown in the figure, this specific embodiment provides a rear suspension assembly fixture, including a base 1, two sets of support components and two sets of clamping components. The two support components are movably disposed at both ends of the base 1, and the two support components move in opposite directions. The clamping components are disposed on the top of the support components and are used to clamp the rear suspension assembly. The clamping components include a mounting base 2, and the mounting base 2 has rotatably disposed on both sides with gripper components, and the two gripper components rotate in opposite directions.

[0036] This specific embodiment, through the cooperation of the support component and the clamping component, can support the pre-assembled rear suspension as a whole (the two individual assemblies on the left and right sides, as well as the connecting axle, balance shaft, and other components in the middle). Compared with the prior art, it can improve the installation accuracy of the structural components at both ends of the suspension assembly, and avoid tire wear and vehicle deviation caused by large installation errors. At the same time, by making the support component movable, the clamping position can be adjusted according to the length of the assembly, thus expanding the applicability of this tooling.

[0037] like Figure 1 and Figure 3 As shown, in this specific embodiment, the support assembly includes a movable seat 3 and a movable drive component. Two movable seats 3 are movably and symmetrically arranged on the base 1. The movable seats 3 of both support assemblies are connected to the movable drive component. The movable drive component is arranged on the base 1. A support plate 4 is provided on the movable seat 3, and the mounting seat 2 is provided on the support plate 4. By symmetrically arranging the two movable seats 3 and connecting them to the same movable drive component, it can be ensured that the movable seats 3 at both ends are always symmetrical about the center of the base 1 after movement, which meets the support requirements of rear suspension assemblies of different sizes and ensures the flexible use of this tooling.

[0038] like Figure 3As shown, the moving drive can be a double-headed hydraulic cylinder, which drives two moving seats 3 simultaneously through two piston rods. In this specific embodiment, to facilitate control and reduce wiring, the moving drive is a moving motor 15, which is mounted on the base 1. The moving motor 15 is connected to a driving bevel gear 14. A guide rod 11 and a lead screw 10 are provided through the moving seat 3. The guide rod 11 is mounted on the base 1, and a driven bevel gear 16 is provided at the end of the lead screw 10. The driven bevel gear 16 interacts with the driving bevel gear 14. Gear 14 meshes; specifically, the movable seat 3 has sliding grooves at both ends and an installation cavity in the middle. The sliding grooves are connected to the installation cavity. The movable motor 15 is installed in the installation cavity. Two guide rods 11 are installed in the sliding groove. One end of the lead screw 10 is installed in the sliding groove through a bearing, and the other end extends into the installation cavity and is equipped with a driven bevel gear 16. The two driven bevel gears 16 are arranged opposite to each other. When the movable motor 15 rotates, the power is transmitted from the driving bevel gear 14 to the lead screw 10, which drives the corresponding movable seat 3 to move in the opposite direction, thereby realizing the adjustment of the distance between the two support components.

[0039] like Figure 4 As shown, to facilitate the movement and storage of this tooling when unloaded, in this specific embodiment, the movable seat 3 is provided with an installation groove and a limiting plate. The support plate 4 is rotatably mounted on the movable seat 3 via a rotating shaft 18. A torsion spring 17 is provided between the installation groove and the support plate 4. When the support plate 4 is under load, it is in a vertical state, and the outer side of the support plate 4 is close to the limiting plate. At this time, the torsion spring 17 stores energy. When the tooling is unloaded, the torsion spring 17 releases energy, and the support plate 4 rotates to a horizontal position close to the base 1. After the support plate 4 is laid flat, it does not interfere with the frame or other objects when moving, and it is also easy to store, reducing space occupation.

[0040] like Figure 2As shown, further in this specific embodiment, two gripper assemblies are symmetrically arranged on the mounting base 2. Each gripper assembly includes a rotating frame 7 and a clamping drive component. The rotating frame 7 is provided with a clamping plate 6 and is rotatably mounted within the mounting base 2 via a transmission shaft 8. The mounting base 2 has a U-shaped structure, and both transmission shafts 8 are connected to the clamping drive component. Furthermore, the clamping plate 6 is provided with a mounting cylinder, which is rotatably mounted on the support rod of the rotating frame 7. By rotatably connecting the clamping plate 6 to the rotating frame 7, the clamping plate 6 can be finely adjusted according to the structure of the corresponding components of the suspension assembly during clamping, increasing the clamping distance between the clamping plate 6 and the corresponding components. The contact area is increased to enhance support reliability; the mounting base 2 is connected to the support plate 4 through a damping shaft 9, which allows the mounting base 2 to rotate under external force during support, ensuring compatibility with rear suspension assemblies of different structures; in this specific embodiment, the clamping drive component is a clamping motor 13, which is connected to a worm gear 12. The worm gear 12 is vertically arranged and rotatably mounted on the mounting base 2 through bearings. A worm wheel 5 is provided on the transmission shaft 8, and two worm wheels 5 are respectively located on both sides of the worm gear 12; when the clamping motor 13 drives the worm gear 12 to rotate, the worm wheels 5 on both sides rotate in opposite directions at the same time, causing the two rotating frames 7 to swing in opposite directions.

[0041] To facilitate control and improve the automation level of this tooling, the tooling also includes a controller and a touch screen display. The controller is electrically connected to the moving motor 15 and the clamping motor 13. The touch screen can input the model of the suspension assembly and the corresponding commands. An emergency stop button is also provided on the touch screen to improve the safety of using this tooling.

[0042] The method of using this tooling is as follows:

[0043] Adjust the distance between the two moving seats 3 according to the size of the suspension assembly to ensure that the distance between the two clamping components is adapted to the suspension assembly and that the clamping components can clamp the axle head of the suspension assembly; lift the support plate 4 to a vertical position, place the suspension assembly on the fixture by hoisting, and control the clamping components to clamp the axle head; move the fixture to the designated position and wait for the vehicle frame to arrive. Specific Implementation Method Two

[0045] like Figure 5 and Figure 6As shown, this specific embodiment provides a rear suspension assembly fixture, which is basically the same as the rear suspension assembly fixture in Specific Embodiment 1, except that: this fixture also includes a movable lifting assembly, and four movable lifting assemblies are provided; the movable lifting assembly includes a support housing 27, which is located at the lower part of the base 1, and a hydraulic cylinder 23 is provided inside the support housing 27. The cylinder body of the hydraulic cylinder 23 is located at the top of the support housing 27, and the piston rod is connected to a lifting plate 24. The lifting plate 24 is movably and vertically arranged inside the support housing 27, and a guide rail 26 is also provided between the lifting plate 24 and the inner wall of the support housing 27 to ensure the stable movement of the lifting plate 24; rollers 2 are provided at the lower part of the lifting plate 24. 5. The roller 25 can fully extend into the support housing 27, and a brake is provided on the roller 25. When the tooling moves into position, the hydraulic cylinder 23 controls the lifting plate 24 to rise, driving the roller 25 to retract into the support housing 27, and the support housing 27 contacts the ground and stops moving, thus locking the position. When movement is required, the hydraulic cylinder 23 drives the lifting plate 24 to move downward until the roller 25 contacts the ground. When the lifting plate 24 continues to descend, the hydraulic cylinder 23 drives the base 1 to rise to a set height, at which point the base 1 can be pushed. When the base 1 needs to be raised, the hydraulic cylinder 23 continues to extend, driving the lifting plate 24 to continue to descend until it is located at the port of the support housing 27, and the base 1 reaches its highest position.

[0046] This specific embodiment uses a movable lifting component to raise and lower the base 1. When used in conjunction with a ground conveyor line, it can prevent interference and collision between the suspension assembly and the vehicle frame, ensuring smooth assembly. At the same time, it can adjust the height of the suspension assembly to match various vehicle models.

[0047] like Figure 5 As shown, preferably, this tooling also includes a positioning component, which is disposed on the base 1 and located between the two support components. The positioning component includes a positioning plate 19, which has a U-shaped structure and can support the corresponding crossbeam of the chassis. By setting the positioning component, the suspension assembly can be positioned in the front-rear direction with the frame through the crossbeam on the frame, thereby improving the installation efficiency of the suspension assembly and the frame. During installation, the positioning plate 19 can quickly locate the front-rear position of this tooling relative to the frame (in the direction of vehicle length) without the need for multiple push-pull adjustments, which is beneficial to improving assembly efficiency. Specifically, a bracket 21 is provided in the middle of the base 1, and a lifting cylinder 20 is provided on the bracket 21. The top of the telescopic rod of the lifting cylinder 20 is rotatably provided with the positioning plate 19 through a pin.

[0048] To facilitate left and right (in the direction of vehicle width) movement, push-pull rods 22 are also horizontally installed at both ends of the base 1.

[0049] As can be seen from the above specific embodiments, this utility model has the following beneficial effects:

[0050] 1. Through the cooperation of the support components and clamping components, the pre-assembled rear suspension can be supported as a whole. Compared with the existing technology, it can improve the installation accuracy of the structural components at both ends of the suspension assembly and avoid tire wear and deviation.

[0051] 2. By setting the torsion spring 17, the support plate 4 can automatically rotate to a position parallel to the base 1 after the rear suspension assembly is not supported, which facilitates transportation and storage;

[0052] 3. By rotatably connecting the clamping plate 6 to the rotating frame 7, the clamping plate 6 can be finely adjusted according to the structure of the corresponding components of the suspension assembly during clamping, thereby increasing the contact area between the clamping plate 6 and the corresponding components and enhancing the reliability of the support.

[0053] 4. By setting up a movable lifting component, the base 1 can be moved, raised, lowered, and locked, making it convenient to use;

[0054] 5. By setting up positioning components, the suspension assembly can be positioned in the front-to-back direction with the frame via the crossbeams on the frame, improving the installation efficiency of the suspension assembly and the frame.

[0055] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
