Description

Technical Field

[0001] This utility model belongs to the field of auxiliary tooling technology, and specifically relates to a tooling for assisting in the assembly of suspension assemblies and vehicle frames. Background Technology

[0002] With the diversification of the intelligent vehicle market, especially the strong development of drive-by-wire chassis in recent years, the market for micro low-speed drive-by-wire chassis has also flourished. Currently, commonly used rear suspensions for micro drive-by-wire chassis include multi-link independent suspension, double wishbone independent suspension, and torsion beam suspension. For some heavy-duty micro drive-by-wire chassis, due to the large weight of the cargo they carry (approximately 1.2 tons), the rear suspension is often a leaf spring suspension or a multi-link non-independent suspension (coil spring). When assembling a multi-link non-independent suspension with the chassis in a heavy-duty micro drive-by-wire chassis, the high linear stiffness (approximately 150 N / mm) and resistance to bending of coil springs result in low efficiency during assembly and production.

[0003] For example, when assembling a multi-link non-independent suspension with the vehicle frame, the frame spring connector is first aligned with the suspension spring. Then, sandbags or other heavy objects are continuously piled on the frame. Only after the sandbags or heavy objects have accumulated a certain mass and the springs are compressed to a certain extent can the trailing arm front mounting bolts and shock absorber mounting bolts be installed. Although this method can assemble the suspension, it is very dangerous. When piling sandbags or heavy objects, it is necessary to ensure that the sandbags or heavy objects are stacked neatly and that their center of gravity is on the spring's load-bearing axis. Slight carelessness in operation could cause the sandbags or heavy objects to tip over, or the springs to pop out, threatening the safety of the workers and causing a major accident. Therefore, assembling a multi-link non-independent suspension with the vehicle frame without any assembly equipment is very difficult. The springs are stiff and not easily bent, requiring at least three people to work together when assembling the suspension. Currently, most low-speed drive-by-wire chassis electric vehicles on the market, such as low-speed intelligent logistics delivery vehicles, low-speed express delivery vehicles, and some low-speed shuttle vehicles, do not have specific devices for equipping their suspension and chassis.

[0004] To ensure assembly production efficiency, using an auxiliary assembly tooling is currently a means to improve production efficiency. Utility Model Content

[0034] 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.

[0035] The core of this utility model is to provide a tooling for assisting in the assembly of the suspension assembly and the vehicle frame, making the assembly operation more convenient and faster, and reducing operational risks.

[0036] To enable those skilled in the art to better understand the technical solutions provided by this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] For details, please refer to Figures 1-7 The present invention provides a tooling for assisting in the assembly of a suspension assembly and a vehicle frame, comprising: a U-shaped bracket 220 and a telescopic mechanism.

[0038] The U-shaped bracket 220 includes a top frame, a bottom frame, and an intermediate frame connecting the top frame and the bottom frame. In use, the U-shaped bracket 220 is C-shaped with its opening horizontally oriented. The top frame of the U-shaped bracket 220 is connected to one end of the telescopic mechanism, and the bottom frame of the U-shaped bracket 220 is used to abut against the lower surface of the suspension assembly 120.

[0039] The other end of the telescopic mechanism abuts against the upper surface of the frame 110 to achieve the telescopic function. A clamping space is formed between the bottom frame of the U-shaped bracket 220 and the other end of the telescopic mechanism for mounting the suspension assembly 120 and the frame 110. The suspension assembly 120 and the frame 110 are placed within the clamping space of the tooling. The telescopic mechanism can be any power-driven device with telescopic functionality, mainly composed of a drive unit, a transmission unit, telescopic rods, and connecting parts. The drive unit provides power, the transmission unit transmits power to the telescopic rods, and the connecting parts connect the telescopic rods to the overall mechanism. When the drive unit rotates, the transmission unit drives the telescopic rods to achieve telescopic movement, thereby allowing the entire telescopic mechanism to shorten or lengthen.

[0040] When the telescopic mechanism extends, the tooling can push the suspension assembly 120 and the frame 110 closer together until the mounting points of the suspension assembly 120 and the frame 110 are aligned. After assembly is complete, the telescopic mechanism retracts, allowing the tooling to be removed from the suspension assembly 120 and the frame 110.

[0041] like Figure 4 and Figure 5 As shown, when the telescopic mechanism is extended, it lifts the U-shaped bracket 220 as a whole, causing the suspension assembly 120 to move upward relative to the frame 110, compressing the coil spring 130 of the suspension assembly 120 until the trailing arm front mounting point 150 and the shock absorber upper mounting point 170 on the suspension assembly 120 move upward and align with the trailing arm front mounting bracket 140 and the shock absorber upper mounting bracket 160 on the frame 110. Then, mounting bolts are used to connect the trailing arm front mounting point 150 to the trailing arm front mounting bracket 140 and the shock absorber upper mounting point 170 to the shock absorber upper mounting bracket 160, thereby achieving the desired result.

[0042] This solution provides a tooling for assisting in the assembly of the suspension assembly and the vehicle frame. The suspension assembly 120 and the vehicle frame 110 are connected by a U-shaped bracket 220 and a telescopic mechanism. The end of the telescopic mechanism abuts against the upper surface of the vehicle frame 110, and the bottom frame of the U-shaped bracket 220 abuts against the lower surface of the suspension assembly 120. During assembly, the telescopic mechanism is extended, lifting the U-shaped bracket 220 as a whole, thereby moving the suspension assembly 120 upward relative to the vehicle frame 110 until the mounting points of the suspension assembly 120 and the vehicle frame 110 are aligned. The mounting points are fixedly connected by mounting bolts, thereby achieving the assembly of the suspension assembly 120 and the vehicle frame 110.

[0043] The above setup utilizes tooling to assemble the suspension assembly 120 and the frame 110, making the assembly operation more convenient and faster, and reducing operational risks.

[0044] In a specific embodiment, the bottom frame of the U-shaped bracket 220 is provided with a lower bracket 210 in the vertical direction. The lower bracket 210 is used to abut against the lower surface of the suspension assembly 120. The lower bracket 210 provides a support position for abutting against the suspension assembly 120.

[0045] Correspondingly, the top frame of the U-shaped bracket 220 is provided with an upper bracket 230 in the vertical direction, and the upper bracket 230 is connected to one end of the telescopic mechanism. The upper bracket 230 provides a connection position for installation with the telescopic mechanism.

[0046] In a further specific embodiment, the lower bracket 210 is threadedly connected to the bottom frame. Specifically, the lower bracket 210 has an external thread, and the corresponding position on the bottom frame has an internal threaded hole that mates with the external thread. The lower bracket 210 and the U-shaped bracket 220 are threadedly connected, allowing adjustment of the extension length of the lower bracket 210 on the U-shaped bracket 220. Alternatively, other locking devices can be used to achieve both adjustment and locking of the lower bracket 210 and the bottom frame.

[0047] The upper bracket 230 is threadedly connected to the top frame. Specifically, the upper bracket 230 has external threads, and the corresponding position on the top frame has an internal threaded hole that mates with the external threads. The upper bracket 230 and the U-shaped bracket 220 are threadedly connected, allowing adjustment of the extension length of the upper bracket 230 onto the U-shaped bracket 220. Alternatively, other locking mechanisms can be used to achieve both adjustment and locking of the upper bracket 230 and the top frame.

[0048] To prevent wear when the lower bracket 210 contacts the suspension assembly 120, a gasket is provided at the connection end between the lower bracket 210 and the suspension assembly 120 to provide some cushioning. The gasket can be made of rubber or other flexible materials with a certain degree of elasticity.

[0049] The number of lower support 210 and / or upper support 230 can be one or more. Multiple lower support 210 and / or upper support 230 can be evenly arranged on U-shaped support 220 to achieve force balance.

[0050] In a specific embodiment, a jack can be used as the lifting equipment for assembly operations in the telescopic mechanism. The jack includes hydraulic jacks, electric jacks, or manual jacks, etc., and can be selected according to actual needs.

[0051] For a manual jack, the specific structure includes a jack body 310 and a rocker arm 320. The rocker arm 320 is used to drive the lifting and lowering of the jack body 310. The rocker arm 320 acts as a lifting component, used to lift or lower heavy objects.

[0052] To improve structural strength, the U-shaped bracket 220 can be made of metal.

[0053] The U-shaped bracket 220 can be a one-piece molded structure or a split structure.

[0054] In one specific embodiment, when the suspension assembly 120 and the frame 110 are assembled, the rocker arm 320 is cranked to extend the jack. The jack body 310 moves upward and drives the upper bracket 230 to move upward. The upper bracket 230 then drives the U-shaped bracket 220 and the lower bracket 210 to move upward. The lower bracket 210 drives the suspension assembly 120, the trailing arm front mounting point 150, the shock absorber upper mounting point 170, the coil spring 130, etc., to move upward. When the suspension assembly 120... When the trailing arm front mounting point 150 and the shock absorber upper mounting point 170 are moved to the trailing arm front mounting bracket 140 and the shock absorber upper mounting bracket 160 on the frame 110, the trailing arm front mounting point 150 and the trailing arm front mounting bracket 140, the shock absorber upper mounting point 170 and the shock absorber upper mounting bracket 160 are fixed with mounting bolts. At this time, the suspension assembly 120 and the frame 110 are assembled. The above tooling has higher assembly efficiency and can effectively improve the operational safety factor.

[0055] This solution improves assembly operations by modifying the assembly method, resulting in a simpler structure, lower cost, and more convenient and efficient process. It also reduces operational risks and enhances assembly safety and efficiency.
