Description

Technical Field

[0001] This invention relates to the field of vehicle manufacturing technology, and in particular to a split torsion shaft steering suspension assembly device. Background Technology

[0002] Currently, the half-shaft structure in vehicle transmission systems is mainly divided into two types. For example... Figure 1 The A-type half-shaft shown is a traditional frame (or axle) half-shaft structure, with a spline at the inner end and a flange at the outer end. During assembly, the inner spline is connected and then directly press-fitted. The outer flange is fixed by tightening bolts. The assembly process is simple and can be efficiently completed using existing half-shaft press-fit machines.

[0003] However, with the optimization of the chassis structure design, issues such as... have emerged. Figure 2 and Figure 3 The diagram shows a Type B half-shaft structure where the torsion shaft mates with the crankshaft. The assembly requirements for this half-shaft structure are more complex. Both the inner and outer ends of the torsion shaft have splines. The outer spline of the torsion shaft needs to connect with the first inner spline of the crankshaft. Then, the mated crankshaft is press-fitted into the suspension support base, ensuring that the second inner spline of the crankshaft mates with the outer spline of the suspension support base. Figures 4 to 6 As shown. This process demands extremely high assembly precision, requiring that the splines on three key mating surfaces be correctly engaged during press-fitting: the torque shaft and crankshaft, and the crankshaft and suspension support base must all achieve precise spline engagement. If the circumferential phase of the splines is not precisely aligned, not only will press-fitting be unable to continue, but it may also cause parts to collide, be crushed, or even be completely scrapped.

[0004] Currently, conventional crankshaft press-fit machines are only suitable for pressing A-type crankshafts without external splines. For B-type crankshaft structures, due to the lack of an automatic positioning and circumferential alignment mechanism for multi-stage splines during the press-fit process, existing press-fit machines cannot directly complete this process. Currently, the industry mostly relies on manual visual inspection and hammering to press the crankshaft in step by step for this combination structure. This manual hammering press-fit method not only requires extremely high levels of worker experience but also suffers from high labor intensity, extremely low assembly efficiency, and poor press-fit consistency, making it difficult to meet the needs of large-scale production. Summary of the Invention

[0005] The purpose of this invention is to provide a split torsion shaft steering suspension assembly device to solve the problems of high labor intensity, low efficiency, and difficulty in guaranteeing assembly quality caused by manual hammering and pressing.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] In a first aspect of this application, a split torsion shaft steering suspension assembly is provided, comprising:

[0008] The workbench has a pressing station on its surface, which is used to press the pre-assembled split torsion shaft and crankshaft of the steering suspension relative to the suspension support base to the assembly position.

[0009] The pressing mechanism, with two pressing mechanisms distributed at both ends of the pressing station, is used to act on the crankshaft and push the crankshaft to move in the direction of the suspension support base to complete the pressing action;

[0010] The suspension load-bearing fixing mechanism is used to support and fix the torsion shaft, crankshaft, and suspension support base of the pre-assembled split torsion shaft steering suspension.

[0011] Based on the first aspect, in one possible implementation, the workbench is further provided with a pre-assembly station, which is used to pre-assemble the suspension support base, torsion shaft and crankshaft of the split torsion shaft steering suspension. The suspension bearing fixing mechanism is reciprocating between the pre-assembly station and the pressing station on the workbench surface.

[0012] Based on the first aspect, in one possible implementation, the suspension bearing fixing mechanism includes a bearing platform and bearing fixing seats. The bearing platform is reciprocally movable between the pre-assembly station and the pressing station and is disposed on the table surface of the workbench. A plurality of the bearing fixing seats are disposed on the bearing platform.

[0013] Based on the first aspect, in one possible implementation, at least one of the bearing fixing seats is adjustablely disposed on the bearing platform, and / or, the bearing fixing seat includes a fixing seat body and a limiting baffle, the top of the fixing seat body is provided with a U-shaped opening groove, and the limiting baffle is detachably disposed on the top of the fixing seat body to close the opening of the U-shaped opening groove, forming a fixing groove adapted to the suspension support base.

[0014] Based on the first aspect, in one possible implementation, the suspension bearing fixing mechanism is slidably disposed on the table surface of the workbench via a guide sliding mechanism. The guide sliding mechanism includes a guide slide rail and a guide slide groove. One of the guide slide rail and the guide slide groove is disposed on the table surface of the workbench, and the other is disposed on the suspension bearing fixing mechanism. The guide slide rail and the guide slide groove are slidably engaged.

[0015] Based on the first aspect, one possible implementation also includes a limiting mechanism, which is disposed on the table surface of the workbench or the guide sliding mechanism, and the limiting mechanism is at least used to limit the suspension bearing fixing mechanism at one end of the sliding stroke of the suspension bearing fixing mechanism near the pressing station.

[0016] Based on the first aspect, in one possible implementation, the limiting mechanism includes a limiting bracket and a buffer pad. The limiting bracket is disposed on the table surface of the workbench, and the buffer pad is disposed on the limiting end of the limiting bracket to contact and cooperate with the suspension bearing fixing mechanism.

[0017] Based on the first aspect, one possible implementation also includes a positioning mechanism, which is at least used to lock the suspension bearing fixing mechanism at the pressing station.

[0018] Based on the first aspect, in one possible implementation, the positioning mechanism includes a positioning base and a positioning pin. The positioning base is disposed on the table surface of the workbench, and the positioning pin passes through a through hole on the suspension bearing fixing mechanism and engages with a positioning pin hole on the positioning base to lock the suspension bearing fixing mechanism at the pressing station.

[0019] Based on the first aspect, in one possible implementation, the workbench is provided with clearance structures at both ends of the pre-assembly station to reserve personnel operating space for the pre-assembly of the split torsion shaft steering suspension.

[0020] Based on the first aspect, in one possible implementation, the pressing mechanism includes a pressing base, a press, and a pressing block. The pressing base is disposed on the table surface of the workbench, the press is disposed on the pressing base, and the pressing block is disposed on the execution end of the press, for applying pressure to the crankshaft under the drive of the press.

[0021] Based on the first aspect, in one possible implementation, the height of the press-fit base and / or the suspension bearing fixing mechanism is adjustable.

[0022] Based on the first aspect, in one possible implementation, at least one of the pressing bases is adjustablely positioned on the table surface of the workbench so that the distance between the two pressing mechanisms is adjustable.

[0023] As can be seen from the above technical solutions, the split torsion shaft steering suspension assembly device provided by the present invention includes a worktable, a pressing mechanism, and a suspension bearing and fixing mechanism. The worktable has a pressing station on its surface, which is used to press the pre-assembled split torsion shaft and crankshaft of the split torsion shaft steering suspension relative to the suspension support base to the assembly position. Two pressing mechanisms are distributed at both ends of the pressing station and are used to act on the crankshaft and push the crankshaft to move in the direction of the suspension support base to complete the pressing action. The suspension bearing and fixing mechanism is used to support and fix the pre-assembled split torsion shaft, crankshaft, and suspension support base of the split torsion shaft steering suspension.

[0024] In application, the pre-assembled split torsion shaft steering suspension is fixed to the suspension bearing fixing mechanism. The two ends of the crankshaft are respectively aligned with the execution ends of the two pressing mechanisms located at both ends of the pressing station. At this time, the outer spline of the inner end of the torsion shaft has been correctly matched with the inner spline in the suspension support base, and the outer spline of the outer end of the torsion shaft has been correctly matched with the first inner spline of the crankshaft. At this time, the second inner spline of the crankshaft and the outer spline of the suspension support base are still some distance away before they can make contact.

[0025] The press-fitting mechanism applies pressure to the crankshaft, bringing it into contact with the suspension support base. After aligning the second internal spline of the crankshaft with the external spline of the suspension support base, the press-fitting mechanism continues to apply pressure to the crankshaft until it is press-fitted relative to the suspension support base into the assembly position. Once the crankshaft is in place, the press-fitting mechanism retracts, removing the press-fitted split torsion shaft steering suspension, preparing for the next workpiece cycle.

[0026] The split torsion shaft steering suspension assembly device in this application uses a press-fit mechanism instead of traditional manual hammering. This not only frees operators from heavy physical labor but also eliminates human interference factors such as visual inspection and inconsistent hammering force, effectively ensuring the consistency of the split torsion shaft steering suspension assembly. Furthermore, the press-fit mechanism provides controllable and uniform axial thrust, which, combined with the limiting support provided by the suspension load-bearing fixing mechanism, effectively solves the problem of spline phase misalignment during manual hammering. During the press-fit process, it ensures the correct meshing of the multi-stage splines between the crankshaft and the suspension support base, and between the crankshaft and the torsion shaft, avoiding spline breakage, part deformation, or even scrapping caused by forced hammering. Simultaneously, the automated or semi-automated press-fit process achieved through the press-fit mechanism simplifies the operation steps, shortens the cycle time for single-piece press-fitting, and effectively meets the needs of large-scale continuous production.

Detailed Implementation

[0040] The core of this invention is to provide a split torsion shaft steering suspension assembly device. The structural design of this split torsion shaft steering suspension assembly device enables it to solve the problems of high labor intensity, low efficiency, and difficulty in guaranteeing assembly quality caused by manual hammering and pressing.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] like Figures 2 to 6 As shown, the split torsion shaft steering suspension involved in this application is mainly composed of three parts: suspension support base 300 (vehicle frame / axle housing), torsion shaft 100 and crankshaft 200. Among them, as the rigid load-bearing skeleton of the entire suspension assembly, it has a dedicated spline structure machined inside and at both ends, and is hollow inside to accommodate the torsion shaft 100.

[0043] The torsion shaft 100 is the core component of the suspension assembly that generates the spring effect. It is a steel shaft with high torsional strength and external splines at both ends (e.g., Figure 2 As shown, the torsion shaft 100 is not directly connected to the wheel, but is hidden inside the suspension support base 300.

[0044] The crankshaft 200 is L-shaped or bent (e.g.) Figure 3 (As shown). The crankshaft 200 is splined to the outer end of the torsion shaft 100, and is also splined to the suspension support base 300. The up-and-down movement of the wheel during bouncing is converted into a torsional force on the torsion shaft 100 inside the suspension support base 300 through the crankshaft 200.

[0045] When the vehicle encounters bumps and the wheels bounce up and down, the crankshaft 200 rotates around its axis. The rotation of the crankshaft 200 directly drives the internal torsion shaft 100 to twist. The torsion shaft 100 resists the torsion by the elastic deformation of its own material, thus acting as a spring similar to a traditional coil spring or leaf spring, supporting the weight of the vehicle and cushioning the impact of the road surface.

[0046] Unlike traditional suspensions, which are typically one-piece or welded structures that do not require spline positioning, the split torsion shaft steering suspension involved in this application requires two sets of splines to engage precisely and simultaneously between the crankshaft 200 and the torsion shaft 100, and between the crankshaft 200 and the suspension support base 300. If the splines are not aligned correctly, forced installation will damage the parts. Traditional manual hammering is not only labor-intensive and inefficient, but also cannot guarantee the accuracy of the spline fit.

[0047] To address the aforementioned issues, this application provides a split torsion shaft steering suspension assembly device. Please refer to [link / reference]. Figure 7 The split torsion shaft steering suspension assembly device includes a worktable 400, a pressing mechanism 600, and a suspension load-bearing fixing mechanism 500.

[0048] The workbench 400 has a press-fit station 410 on its surface. The press-fit station 410 is used to press the pre-assembled split torsion shaft 100 and crankshaft 200 of the split torsion shaft steering suspension relative to the suspension support base 300 to the assembly position. Two press-fit mechanisms 600 are distributed at both ends of the press-fit station 410. They are used to act on the crankshaft 200 and push the crankshaft 200 towards the suspension support base 300 to complete the press-fit action. The suspension bearing and fixing mechanism 500 is used to support and fix the pre-assembled split torsion shaft 100, crankshaft 200 and suspension support base 300 of the split torsion shaft steering suspension. That is, the suspension bearing and fixing mechanism 500 is used to fix the pre-assembled split torsion shaft steering suspension to ensure its positional stability.

[0049] In application, the pre-assembled split torsion shaft steering suspension is fixed to the suspension bearing fixing mechanism 500. The two ends of the crankshaft 200 are respectively aligned with the execution ends of the two pressing mechanisms 600 located at both ends of the pressing station 410. At this time, the outer spline at the inner end of the torsion shaft 100 is correctly engaged with the inner spline in the suspension support base 300, and the outer spline at the outer end of the torsion shaft 100 is also correctly engaged with the first inner spline of the crankshaft 200. At this time, the second inner spline of the crankshaft 200 and the outer spline of the suspension support base 300 are still some distance away before they can make contact.

[0050] The press-fitting mechanism 600 applies pressure to the crankshaft 200, causing the crankshaft 200 to contact the suspension support base 300, such as... Figure 8As shown, after aligning the second internal spline of the crankshaft 200 and the external spline of the suspension support base 300, the press-fitting mechanism 600 continues to apply pressure to the crankshaft 200 until the crankshaft 200 is press-fitted relative to the suspension support base 300 into the assembly position, as shown. Figure 9 As shown, after the pressing is completed, the pressing mechanism 600 retracts, removes the split torsion shaft steering suspension that has been pressed, and prepares to enter the cycle of the next workpiece.

[0051] Compared with existing technologies, the split torsion shaft steering suspension assembly device provided in this application uses a press-fit mechanism 600 instead of traditional manual hammering. This not only frees operators from heavy physical labor but also eliminates human interference factors such as visual inspection and inconsistent hammering force, effectively ensuring the consistency of the split torsion shaft steering suspension assembly. Furthermore, the press-fit mechanism 600 provides controllable and uniform axial thrust, which, combined with the limiting support provided by the suspension load-bearing fixing mechanism 500, effectively solves the problem of spline phase misalignment during manual hammering. During the press-fit process, it ensures the correct meshing of the multi-stage splines between the crankshaft 200 and the suspension support base 300, and between the crankshaft 200 and the torsion shaft 100, avoiding spline breakage, part deformation, or even scrapping caused by forced hammering. Simultaneously, the automated or semi-automated press-fit process achieved through the press-fit mechanism 600 simplifies the operation steps, shortens the cycle time for single-piece press-fitting, and effectively meets the needs of large-scale continuous production.

[0052] As described above in the working process of the split torsion shaft steering suspension assembly device, before the pressing process, the suspension support base 300, torsion shaft 100, and crankshaft 200 of the split torsion shaft steering suspension need to be pre-assembled. To facilitate the pre-assembly process, in one embodiment of this application, as shown... Figure 7 As shown, a pre-assembly station 420 is also provided on the workbench 400. The pre-assembly station 420 is used to pre-assemble the suspension support base 300, torsion shaft 100 and crankshaft 200 of the split torsion shaft steering suspension. The suspension bearing fixing mechanism 500 is set on the workbench 400 and can reciprocate between the pre-assembly station 420 and the pressing station 410.

[0053] Please see Figure 10 The suspension load-bearing fixing mechanism 500 is moved to the pre-assembly station 420, and the suspension support base 300 is fixed onto the suspension load-bearing fixing mechanism 500. Then, the torsion shaft 100 and crankshaft 200 are sequentially assembled onto the suspension support base 300 to complete the pre-assembly. Then, the suspension load-bearing fixing mechanism 500, together with the pre-assembled split torsion shaft steering suspension on it, is moved to the press-fitting station 410. Figure 8 As shown, this is to complete the subsequent pressing process.

[0054] Please continue reading. Figure 7The suspension load fixing mechanism 500 includes a load platform 510 and a load fixing seat 520. The load platform 510 is reciprocally movable on the table surface of the workbench 400 between the pre-assembly station 420 and the press-fit station 410. Multiple load fixing seats 520 are disposed on the load platform 510. The load fixing seats 520 are used to cooperate with the suspension support base 300 of the split torsion shaft steering suspension to fix the split torsion shaft steering suspension on the suspension load fixing mechanism 500.

[0055] To facilitate compatibility with split torsion shaft steering suspensions of different specifications, in one embodiment of this application, at least one load-bearing fixing seat 520 is adjustablely disposed on the load-bearing platform 510, so that the distance between at least two load-bearing fixing seats 520 is adjustable. To achieve the positional adjustability of the load-bearing fixing seat 520, a plurality of first mounting holes arranged in an array can be provided on the load-bearing platform 510, and a plurality of second mounting holes can be provided on the load-bearing fixing seat 520. The hole spacing between two adjacent first mounting holes is the same as the hole spacing between two adjacent second mounting holes. Threaded fasteners for fixing the load-bearing fixing seat 520 respectively engage with the first mounting holes and the second mounting holes to fix the load-bearing fixing seat 520 to the load-bearing platform 510. By aligning the second mounting holes of the load-bearing fixing seat 520 with the first mounting holes at different positions on the load-bearing platform 510, the positional adjustability of the load-bearing fixing seat 520 can be achieved.

[0056] Please continue reading. Figure 7 In one embodiment of this application, the bearing fixing seat 520 includes a fixing seat body 521 and a limiting baffle 522. The top of the fixing seat body 521 is provided with a U-shaped opening groove. The limiting baffle 522 is detachably disposed on the top of the fixing seat body 521 to close the opening of the U-shaped opening groove, forming a fixing groove adapted to the suspension support base 300. That is, the fixing groove is closed in the circumferential direction, thereby limiting the suspension support base 300 in the circumferential direction. It should be noted that at least one of the bearing fixing seats 520 can adopt the above structure, while the other bearing fixing seats 520 can only be provided with U-shaped opening grooves without limiting baffles 522, so as to improve the fixing efficiency of the suspension support base 300.

[0057] To prevent damage to the surface of the suspension support base 300 during the fixing process, flexible pads can be provided on the groove wall of the U-shaped opening groove and on the plate surface of the limiting baffle 522 to avoid rigid contact between the suspension support base 300 and the load-bearing fixing seat 520.

[0058] Specifically, such as Figure 7As shown, the suspension bearing fixing mechanism 500 is slidably mounted on the table surface of the workbench 400 via the guide sliding mechanism 700. The guide sliding mechanism 700 includes a guide slide rail 710 and a guide slide groove 720. One of the guide slide rail 710 and the guide slide groove 720 is mounted on the table surface of the workbench 400, and the other is mounted on the suspension bearing fixing mechanism 500. The guide slide rail 710 and the guide slide groove 720 are slidably engaged.

[0059] exist Figure 7 In the embodiment shown, the guide slide 720 is disposed at the bottom of the suspension support fixing mechanism 500, that is, at the bottom of the support platform 510, and the guide slide rail 710 is disposed on the table surface of the workbench 400. In order to ensure the stability of the suspension support fixing mechanism 500 during reciprocating movement, at least two guide sliding mechanisms 700 can be disposed between the suspension support fixing mechanism 500 and the workbench 400, and each guide sliding mechanism 700 is disposed in parallel and spaced apart.

[0060] To ensure that the suspension load-bearing fixing mechanism 500 can accurately move to the pressing station 410, in one embodiment of this application, such as Figure 7 As shown, the split torsion shaft steering suspension assembly device also includes a limiting mechanism 800. The limiting mechanism 800 is disposed on the table surface of the workbench 400 or the guide sliding mechanism 700, and the limiting mechanism 800 is at least used to limit the suspension bearing fixing mechanism 500 at one end of the sliding stroke of the suspension bearing fixing mechanism 500 near the press-fitting station 410.

[0061] Specifically, Figure 7 In the embodiment shown, a limiting mechanism 800 is provided on the table surface of the workbench 400. The limiting mechanism 800 includes a limiting bracket 810 and a buffer pad 820. The limiting bracket 810 is disposed on the table surface of the workbench 400, and the buffer pad 820 is disposed at the limiting end of the limiting bracket 810 so as to contact and cooperate with the suspension bearing fixing mechanism 500.

[0062] In this application, limit mechanisms 800 are respectively provided at both ends of the stroke of the suspension load fixing mechanism 500, so that the suspension load fixing mechanism 500 can be limited at the pre-installation station 420 and the press-fitting station 410 respectively.

[0063] Alternatively, a limiting mechanism 800 can be set between the guide rail 710 and the guide groove 720 of the guide sliding mechanism 700, for example, it can be set between the guide rail 710 and the guide groove 720. Figure 7In the embodiment shown, a limiting block is provided at the end of the guide rail 710. When the guide groove 720 slides along the guide rail 710 to the end of the guide rail 710, it contacts and cooperates with the limiting block to achieve limiting. Alternatively, limiting can be achieved by a limiting pin. That is, a first limiting hole is opened on the suspension bearing fixing mechanism 500, and a second limiting hole is provided on the end of the guide rail 710. The limiting pin passes through the first limiting hole and cooperates with the second limiting hole to achieve limiting.

[0064] To prevent the suspension support fixing mechanism 500 from moving under external force during the press-fitting process, thus affecting stability, in one embodiment of this application, the split torsion shaft steering suspension assembly device further includes a positioning mechanism. The positioning mechanism is at least used to lock the suspension support fixing mechanism 500 at the press-fitting station 410. Of course, the positioning mechanism can also be used to lock the suspension support fixing mechanism 500 at the pre-assembly station 420.

[0065] Specifically, such as Figure 7 As shown, the positioning mechanism includes a positioning base 900 and a positioning pin. The positioning base 900 is set on the table surface of the workbench 400. The positioning pin passes through the through hole on the suspension bearing fixing mechanism 500 and engages with the positioning pin hole on the positioning base 900 to lock the suspension bearing fixing mechanism 500 at the press-fitting station 410.

[0066] To facilitate the pre-assembly process, the workbench 400 is equipped with clearance structures at both ends of the pre-assembly station 420 to provide operating space for personnel during the pre-assembly of the split torsion shaft steering suspension.

[0067] Please continue reading. Figure 7 In one embodiment of this application, the pressing mechanism 600 includes a pressing base 610, a press 620, and a pressing block 630. The pressing base 610 is disposed on the table surface of the workbench 400, the press 620 is disposed on the pressing base 610, and the press 620 is a manual press 620 or an automatic press 620. The pressing block 630 is disposed on the execution end of the press 620 and is used to apply pressure to the crankshaft 200 under the drive of the press 620.

[0068] For example, the height of the press-fit base 610 and / or the suspension support fixing mechanism 500 is adjustable. By adjusting the height of the press-fit base 610 and / or the suspension support fixing mechanism 500, the split torsion shaft steering suspension assembly device in this application embodiment can be adapted to the assembly of various split torsion shaft steering suspensions of different specifications.

[0069] Furthermore, at least one press base 610 is positionally adjustable on the workbench 400 so that the distance between the two press mechanisms 600 is adjustable, thereby enabling the split torsion shaft steering suspension assembly device in this embodiment to be adapted to the assembly of various split torsion shaft steering suspensions of different specifications.
