The front suspension lower control arm 101 can rotate around the front suspension stabilizer bar 100. The front suspension upper bracket 102 includes a front vertical plate and a horizontal base plate that are perpendicular to each other.

[0003] Currently, when the front suspension assembly is installed on the cab, the installation position is at the bottom of the cab. The front vertical plate and horizontal base plate of the front suspension upper bracket are fastened to the longitudinal beam of the cab floor. The fastening points are at the front and bottom of the cab. First, the front vertical plate of the front suspension upper bracket is fastened at the front. The operator needs to flip down the front lower control arm to fasten the horizontal base plate of the front suspension upper bracket.

[0053] It should be noted that any symbols and / or numbers present in the specification that are not marked in the accompanying drawings are not reference numerals.

[0054] Example 1

[0055] See Figure 1 As shown, a commercial vehicle front suspension assembly structure includes a front suspension stabilizer bar 100, a front suspension lower control arm 101 connected to the left and right ends of the front suspension stabilizer bar 100, and a front suspension upper bracket 102. The front suspension upper bracket 102 includes a front vertical plate and a horizontal bottom plate that are perpendicular to each other.

[0056] See Figures 2-5As shown in the embodiment of this application, a front suspension assembly assembly assistive device includes a fixed bracket 5, which provides support and limitation for the front suspension upper bracket; a flip bracket 2, the first end of which is rotatably connected to the first end of the fixed bracket 5; a driving member 6, the first end of which is connected to the second end of the fixed bracket 5, and the second end of which is connected to the second end of the flip bracket 2, and the driving member 6 extends and retracts to drive the flip bracket 2 to rotate; and a push stop 1, which is connected to one side of the flip bracket 2 to prevent the push stop 1 from contacting the surface of the front suspension lower control arm.

[0057] In this embodiment, the front suspension assembly assembly assistive device uses a retractable cylinder as the drive component 6. A handle 7 is bolted to the tilting bracket 2 and connected to both the air source and the cylinder. Operating the handle 7 extends or retracts the cylinder. Since the two ends of the cylinder are connected to the fixed bracket 5 and the tilting bracket 2 respectively, and the first end of the tilting bracket 2 is rotatably connected to the first end of the fixed bracket 5, when the cylinder extends, it drives the tilting bracket 2 to rotate forward relative to the fixed bracket 5. The pusher 1 follows the tilting bracket 2 in rotating forward, at which point the pusher 1 contacts the rear surface of the front suspension lower control arm, pushing the front suspension lower control arm forward to tilt, creating operating space for securing the horizontal base plate of the front suspension upper bracket. When the cylinder retracts, it drives the tilting bracket 2 to rotate backward relative to the fixed bracket 5, and the pusher 1 follows the tilting bracket 2 in rotating backward, at which point the pusher 1 contacts the front surface of the front suspension lower control arm, pushing the front suspension lower control arm backward to its initial position. The cylinder extends and retracts to drive the tilting bracket 2 to rotate relative to the fixed bracket 5. The pusher 1, which rotates with the tilting bracket 2, pushes the front suspension lower control arm to tilt back and forth, replacing manual tilting of the front suspension lower control arm. This reduces the operator's labor intensity, improves production efficiency, ensures assembly quality, and reduces safety hazards. The fixed bracket 5 provides support and limits for the front suspension upper bracket, ensuring the stability of the front suspension assembly when the front suspension lower control arm tilts.

[0058] Furthermore, a rotating shaft 2-1 is provided on one side of the flip bracket 2, and a pusher 1 is sleeved on the rotating shaft 2-1. The pusher 1 is a nylon tube. By sleeved on the rotating shaft 2-1, the pusher 1 is connected to the flip bracket 2. Nylon, as a soft material, can prevent scratches on the paint surface of the front suspension lower control arm.

[0059] Furthermore, the fixed bracket 5 includes a fixed bracket plate 5-2, a bottom support plate 5-4, and a transverse support plate 5-5. The fixed bracket plate 5-2 serves as the main structure of the fixed bracket 5, with its first end rotatably connected to the first end of the flip bracket 2 and its second end connected to the first end of the drive component 6, thereby enabling the flip bracket 2 to rotate relative to the fixed bracket 5. The bottom support plate 5-4 and the transverse support plate 5-5 are located on one side of the fixed bracket plate 5-2. The bottom support plate 5-4 contacts the horizontal base plate of the front suspension upper bracket, providing vertical support and limitation for the front suspension upper bracket. The transverse support plate 5-5 contacts the front vertical plate of the front suspension upper bracket, providing horizontal support and limitation for the front suspension upper bracket, ensuring the stability of the front suspension assembly when the front suspension lower control arm flips.

[0060] Furthermore, the flipping bracket 2 includes an inner bracket plate 2-2 and an outer bracket plate 2-5. The bottoms of the inner bracket plate 2-2 and the outer bracket plate 2-5 are fixed by a welding plate 2-6, and the sides of the inner bracket plate 2-2 and the outer bracket plate 2-5 are fixed by a welding plate 2-4. The second end of the driving component 6 is connected between the inner bracket plate 2-2 and the outer bracket plate 2-5.

[0061] By setting the flipping bracket 2 as inner and outer support plates and connecting the cylinder in the middle of the two support plates, the cylinder is made more stable and does not deviate during operation; the two support plates are firmly welded together by the side welding plate 2-4 and the bottom welding plate 2-6, which enhances the strength of the flipping bracket 2.

[0062] Furthermore, the first end of the fixed bracket plate 5-2 is provided with a flip shaft 5-1, and the first end of the inner bracket plate 2-2 is provided with a connecting hole 2-7 that is rotatably connected to the flip shaft 5-1; the flip shaft 5-1 has a connecting hole 2 along its axial center, and the front suspension assembly assembly assist tool is fixed to the end of the front suspension stabilizer bar through the connecting hole 2. The flip shaft 5-1 is inserted into the connecting hole 2-7 to realize the rotatable connection between the fixed bracket 5 and the flip bracket 2, and the end of the front suspension stabilizer bar is inserted into the connecting hole 2 to connect the assembly assist tool to the front suspension assembly.

[0063] Furthermore, it also includes a pressure plate 3, which is fixed at the connection between the flip shaft 5-1 and the connecting hole 2-7. The pressure plate 3 presses and fixes the connection between the flip shaft 5-1 and the connecting hole 2-7.

[0064] Furthermore, weight-reducing holes are provided on the fixed support plate 5-2, the inner support plate 2-2, and the outer support plate 2-5. While ensuring the strength of the assembly aid, the weight-reducing holes reduce the weight of the assembly aid and decrease the workload of installing it.

[0065] Furthermore, the outer surfaces of the bottom support plate 5-4 and the transverse support plate 5-5 are both covered with a layer of elastic material, preferably polyurethane. Since both the bottom support plate 5-4 and the transverse support plate 5-5 are in contact with the front suspension upper bracket, using elastic material can reduce the risk of paint damage to the front suspension upper bracket.

[0066] Furthermore, a bottom reinforcing rib 5-3 is provided at the connection between the bottom support plate 5-4 and the fixed bracket plate 5-2, and a transverse reinforcing rib 5-6 is provided at the connection between the transverse support plate 5-5 and the fixed bracket plate 5-2. The reinforcing ribs further increase the strength of the fixed bracket 5.

[0067] Example 2

[0068] Reference Figure 5 As shown in the figure, an embodiment of this application provides a front suspension assembly assembly method, which includes the following steps:

[0069] S1. The front vertical plate of the front suspension bracket is assembled;

[0070] S2. Connect the air source to the front suspension assembly power assist tool, insert the end of the front suspension stabilizer bar into the second connection hole opened in the flip shaft 5-1, put the bottom support plate 5-4 into contact with the horizontal bottom plate of the front suspension upper bracket, put the transverse support plate 5-5 into contact with the front vertical plate of the front suspension upper bracket, and put the push stop 1 into contact with the rear surface of the front suspension lower swing arm.

[0071] S3. The operating handle 7 extends the cylinder, and the pusher 1 pushes the front suspension lower control arm to flip forward, making room for the horizontal base plate that is fastened to the front suspension upper bracket.

[0072] S4. Horizontal base plate of the upper bracket before assembly;

[0073] S5. Make the push-gear 1 contact the front surface of the front suspension lower control arm; operate the handle 7 to extend and retract the cylinder, and push-gear 1 pushes the front suspension lower control arm to flip backward to the initial position.

[0074] The front suspension assembly assembly method of this embodiment uses a cylinder to extend and retract the rotating bracket 2 to rotate relative to the fixed bracket 5. The pusher 1, which rotates with the rotating bracket 2, pushes the front suspension lower control arm to rotate back and forth, replacing the manual rotation of the front suspension lower control arm. This reduces the labor intensity of the operator, improves production efficiency, and reduces safety hazards.

[0075] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the systems or apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the descriptions are relatively simple, and relevant parts can be referred to the method section.

[0076] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
