Description

Technical Field

[0001] The invention relates to vehicle assembly, in particular to a suspension subassembly and final assembly device. Background Art

[0002] With the rapid development of new energy vehicles, the importance of rear suspension in vehicle construction has increased. The increase in vehicle load, the rear-mounted drive system and the multi-in-one form, the increase in the complexity and weight of the rear suspension, etc., have increased a large number of replacement verification needs in the R&D stage and a large number of replacement business in the after-sales stage.

[0003] The existing replacement assembly process in the R&D stage and the after-sales stage is to assemble the suspension parts first, and then assemble the compressed coil spring and the rear suspension together with the vehicle body through the spring clip, which leads to long assembly time and high production cost.

The edges of the lifting upper platform 21 are surrounded by limiting retaining edges 212. The base 11 is placed on the embedded balls 211 so that it can move on the lifting upper platform 21 in the forward and backward or left and right directions.

Subsequently, according to the three-coordinate dimensions of the rear suspension of the vehicle model to be assembled, each subframe positioning support assembly 14 is connected to the first slider 126 or the second slider 136 by bolts or other fasteners. Since the number of the first slide rail 125 and the second slide rail 135 is three, there are three installation positions for the first slider 126 and the second slider 136 to choose from in the front and rear directions, thereby realizing the three-level switching of the installation position of each subframe positioning support assembly 14 in the front and rear directions. After the first slider 126 slides to the desired position in the left and right directions, the positions of the first slider 126 and the first slide rail 125 are fixed by bolts or other fasteners. The second slider 136 is similar to the second slider 136, so that the installation position of each subframe positioning support assembly 14 can be adjusted in the left and right directions.

After the alignment is completed, the coil spring is located between the rear suspension and the vehicle body.

[0046] S203, continue to lift the rear suspension so that the assembly zipper 23 is continuously tightened. When the lifting mechanism 22 drives the lower lifting platform 24 and the rear suspension to rise, the assembly zipper 23 can overcome the elastic force of the coil spring to prevent the vehicle body from moving upward, ensuring that the coil spring between the rear suspension and the vehicle body is compressed. After the rear suspension is aligned with the hole, tighten the bolts connecting it to the vehicle body, remove the suspension sub-assembly and final assembly device, and complete the assembly of the rear suspension.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
