Description

Technical Field

[0001] This invention relates to the field of trailer suspension technology, specifically to a prefabricated suspension device. Background Technology

[0002] Currently, the suspension on the market is directly welded to the lower wing plate of the vehicle beam. This type of suspension is prone to material damage and lateral welding stress concentration, which can easily cause problems such as weld cracking and breakage at the suspension when the vehicle is heavily loaded. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide an assembly-type suspension device that is mounted on the vehicle without being welded to the vehicle.

[0004] An assembled suspension device includes two suspension assemblies with an intermediate connecting rod between them. Each suspension assembly includes a suspension mounting plate installed on both sides of a vehicle beam and a suspension side upright plate detachably connected to the suspension mounting plate. Between the two suspension side upright plates, from top to bottom, are arranged a support member, a spring steel plate bearing cylinder, and a tie rod seat. The tie rod seat is located at the bottom end of the suspension side upright plate. A tie rod pin is provided inside the spring steel plate bearing cylinder, and the tie rod pin is connected to the intermediate connecting rod.

[0005] Furthermore, a pin sleeve is provided between the tie rod pin and the two suspension side plates.

[0006] Furthermore, the suspension mounting plates on both sides of the vehicle beam are connected to the suspension side uprights by bolts.

[0007] Furthermore, the support member and the suspension side plate, and the tie rod seat and the suspension side plate are connected by welding.

[0008] Furthermore, the spring steel plate support cylinder is provided with a spring plate balance seat.

[0009] Furthermore, the inner side of each of the suspended side uprights, located below the spring steel plate support cylinder, is a spring plate limiting plate.

[0010] Furthermore, the support member and the suspension side plate, and the tie rod seat and the suspension side plate are connected by welding.

[0011] Advantages of this invention: This invention has a reasonable design. The prefabricated connection of the suspension to the vehicle beam replaces the traditional welding connection, which can effectively solve the problems of stress concentration and material damage caused by suspension welding on the lower flange of the vehicle beam when the vehicle is under heavy load, resulting in problems such as weld breakage and fracture at the suspension. This reduces vehicle maintenance costs and extends the service life of the vehicle. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] An assembled suspension device includes two suspension assemblies with an intermediate connecting rod 1 between them. Each suspension assembly includes a suspension mounting plate 2 installed on both sides of a vehicle beam 1-1 and a suspension side upright plate 3 detachably connected to the suspension mounting plate 2. Between the two suspension side upright plates 3, a support member 4, a spring steel plate support cylinder 5, and a tie rod seat 6 are arranged sequentially from top to bottom. The tie rod seat 6 is located at the bottom end of the suspension side upright plate 3. A tie rod pin 7 is provided inside the spring steel plate support cylinder 5 and is connected to the intermediate connecting rod 1.

[0022] A pin sleeve 8 is provided between the tie rod pin 7 and the two suspension side plates 3.

[0023] The suspension mounting plates 2 and the suspension side uprights 3 on both sides of the vehicle beam 1-1 are connected by bolts.

[0024] The support member 4 and the suspension side plate 3, and the tie rod seat 6 and the suspension side plate 3 are connected by welding.

[0025] The spring steel plate support cylinder 5 is provided with a spring plate balance seat 9.

[0026] The inner side of each of the suspended side uprights 3 is located below the spring steel plate support cylinder 5 and belongs to the spring plate limiting plate 10.

[0027] The support member 4 and the suspension side plate 3, and the tie rod seat 6 and the suspension side plate 3 are connected by bolts.

[0028] The operating principle of this invention is as follows: Under heavy load, the pressure from the weight of the cargo is directly transmitted to the spring plate connected to the axle through the spring steel plate support cylinder connected to the suspension side plate, and then transmitted to the tires on both sides through the axle. Compared with the traditional suspension, the suspension is directly mounted on both sides of the vehicle beam, so there is no stress concentration or material damage to the lower wing plate of the vehicle beam caused by suspension welding.

[0029] Example

[0030] like Figure 5 and Figure 6 As shown, three sets of axles are provided below the vehicle beam 1-1, and the suspension of the present invention is connected to the vehicle beam 1-1 through spring plates 1-5. The spring plates 1-5 are installed on the underside of the axles, namely the front suspension group 1-2, two intermediate suspension groups 1-3 and the rear suspension group 1-4. The tie rod seats 6 at the bottom of the front suspension group 1-2 and the two intermediate suspension groups 1-3 are connected to the axles by tie rods 1-6. The suspension side uprights 3 of the intermediate suspension groups are provided with spring plate balance seats 9.

[0031] The application of this novel invention in this embodiment fully demonstrates the advantages of using a prefabricated connection between the suspension beams, avoiding direct dangers, facilitating later maintenance and replacement, and extending the service life of the vehicle.

[0032] Other examples Figure 7 As shown, when the spring plate 1-5 is installed on the underside of the axle, the position of the tie rod seat 6 can be changed as needed to facilitate the installation of the tie rod 1-6.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
