Description

Technical Field

[0001] This invention belongs to the field of automobile manufacturing. Specifically, this invention relates to a chassis transportation device for mixed-model production lines that carries both load-bearing and non-load-bearing vehicles. Background Technology

[0002] The distinction between monocoque and body-on-frame vehicles is based on their different body structures. Monocoque vehicles lack a rigid frame; by reinforcing the front, rear, sides, and floor, components such as the engine, front and rear suspensions, and parts of the drivetrain are mounted on the body at the designed locations. The load on the body is transmitted to the wheels through the suspension system, and the entire body directly bears various load forces. Body-on-frame vehicles, on the other hand, have a rigid frame, also known as a chassis frame. Components such as the engine, parts of the drivetrain, and the body are fixed to the rigid frame using the suspension system. The frame is connected to the wheels through the front and rear suspension systems. The body primarily bears the weight of passengers and luggage, and the frame is the main structure for installation and load-bearing.

[0003] The chassis of a unibody vehicle consists of multiple independent components, assembled from the front suspension assembly, engine and transmission assembly, powertrain assembly, and rear suspension assembly. In actual production, four auxiliary lines are needed: one for the front suspension assembly, one for the engine and transmission assembly, one for the powertrain assembly, and one for the rear suspension assembly, each handling their respective assembly tasks. The chassis of a body-on-frame vehicle is a monolithic structure, integrating the front suspension, powertrain, and rear suspension onto the frame assembly. In actual production, only two auxiliary lines are needed: one for the engine and transmission assembly and one for the frame assembly, each handling their respective assembly tasks. The differences between the various chassis assemblies of unibody and body-on-frame vehicles directly impact the flexibility, quality, efficiency, and cost of mixed-line production of both types. Therefore, achieving highly flexible, high-quality, high-efficiency, and low-cost mixed-line production of unibody and body-on-frame vehicles has become a major challenge and pain point in the automotive manufacturing industry.

[0004] Therefore, in order to improve or solve at least one of the above problems, a chassis transportation device for mixed production of load-bearing and non-load-bearing vehicles is provided, which can be compatible with mixed production lines for load-bearing and non-load-bearing vehicles, can meet the assembly requirements of various chassis components for load-bearing and non-load-bearing vehicles, is conducive to improving the flexibility of mixed production lines, improving the quality and efficiency of mixed production lines, and reducing the cost of mixed production lines.

[0056] Figure 11This is a schematic diagram of the structure of the rear shock absorber rotating support unit in an embodiment of the present invention.

[0057] like Figure 10 and Figure 11 As shown, the rear floating roof clamping structure 300 also includes a rear shock absorber rotation support unit 316 disposed on the rear floating roof body 301. The rear shock absorber rotation support unit 316 is respectively disposed on both sides of the rear floating roof body 301 and is used for limiting support of the rear suspension rear shock absorber assembly. The rear shock absorber rotation support unit 316 includes a rear shock absorber rotation shaft 3161, a rear shock absorber rotation rod 3162, a rear shock absorber support positioning pin 3163, a rear suspension trailing arm support block 3164, a rear brake disc lower support block 3165, a rear brake disc side support rod 3166, a rear brake disc side support block 3167, and a rear shock absorber support positioning hole 3168. The rear shock absorber rotation shaft 3161 passes through the rear shock absorber rotation rod 3162 and the rear floating roof body 301. The rear suspension trailing arm support block 3164 is disposed on the rear shock absorber rotation rod 3162. On 162, the rear suspension trailing arm support block 3164 is used for limiting and supporting the rear suspension trailing arm, and is made of nylon material to prevent damage to the surface of the parts; the rear brake disc lower support block 3165 is set on the rear shock absorber rotating rod 3162, and is used to support the lower rear brake disc, and is made of nylon material to prevent damage to the surface of the parts; the rear brake disc side support rod 3166 is set on the rear shock absorber rotating rod 3162, and connects the rear brake disc lower support block 3165 and the rear shock absorber rotating rod 3162, and is used to support the rear brake disc side support block 3165; the rear brake disc side support block 3167 is set on the rear brake disc side support rod 3166, and is used to support and limit the side of the rear brake disc, and is made of nylon material to prevent damage to the surface of the parts.

[0058] The rear shock absorber support positioning hole 3168 is provided on the rear floating plate body 301. The rear shock absorber support positioning hole 3168 is located on one side of the rear shock absorber rotating rod 3162. The rear shock absorber support positioning pin 3163 is movably inserted through the rear shock absorber rotating rod 3162. When making way for the spring compression of a non-load-bearing vehicle, the rear shock absorber rotating rod 3162 rotates and retracts, and the rear shock absorber support positioning pin 3163 is inserted into the rear shock absorber support positioning hole 316, thus completing the avoidance.
