Description

Technical Field

[0001] The utility model relates to the technical field of vehicle radiator or cooling module installation structure, in particular to a vehicle radiator suspension. Background Art

[0002] Generally, the cooling module of a passenger car or commercial vehicle includes core components such as a condenser and a radiator. As an important part of the engine cooling system, its function is to force the engine to cool to ensure that the engine water temperature is maintained at a reasonable state and prevent the engine water temperature from being too high and malfunctioning. The condenser and radiator need to be connected to the frame through relevant mounting structures to ensure the stability of their structures. In the prior art, most cooling modules are connected by suspension support and frame, wherein one end of the radiator suspension is connected to the frame and the other end is connected to the radiator, which is used for the fixed connection between the radiator and the frame. In addition, the radiator suspension generally uses a rubber cushion. While supporting and connecting the radiator, the rubber cushion can provide a load-bearing buffer between the radiator and the frame, thereby improving the overall NVH performance of the vehicle. The current radiator suspension needs to adapt to the installation in a small space due to the layout space limitations of the vehicle cabin, and due to the fixed installation of other components in the vehicle cabin, the radiator suspension needs to provide a corresponding installation and fixing interface, so higher requirements are put forward for the integration and lightweight of the radiator suspension.

[0003] Through searching, relevant technical documents on vehicle cooling modules or radiator suspensions, mounting brackets, etc. have been disclosed in the prior art. For example, the utility model patent with the publication number "CN216382338U" and the name "A bushing type cooling water tank suspension mechanism for heavy trucks" is disclosed. A bushing type cooling water tank suspension mechanism for heavy trucks is disclosed, including a bushing suspension, a bushing suspension mounting seat is fixedly installed at the bottom of the bushing suspension, a bushing is fixedly installed inside the bushing suspension, a rubber main spring is fixedly installed inside the bushing suspension, a Y-direction notch is opened on the left side of the bushing suspension, a Z-direction notch is opened on the left side of the bushing suspension, a connecting bolt is movably installed inside the bushing suspension, and an inner sleeve is movably installed inside the bushing suspension. This prior art can provide different stiffness in two directions of the vehicle, and provide limit support while realizing buffer support for the radiator, but it does not consider how to integrate and lightweight design to meet the installation requirements of a small space.

[0004] For example, there is a utility model patent with publication number "CN218257720U" and name "A Radiator Buffer Pad and Automobile". A radiator suspension and a vehicle are provided, wherein the radiator suspension includes a suspension bracket and a rubber component, wherein the suspension bracket is provided with a connection portion connected to an external carrier, and has a receiving hole formed in the middle of the bracket; the rubber component is located in the receiving hole, and the rubber component includes an inner skeleton and a rubber body, the inner skeleton has a suspension hole connected to the radiator, the rubber body is coated on the outer circumference of the inner skeleton, and has two first connecting ribs and two second connecting ribs connected to the suspension bracket, the two first connecting ribs are arranged in an "I" shape, and the two second connecting ribs are arranged in an "eight" shape. This prior art is similar to the above-mentioned prior art. By optimizing the design of the rubber body of the radiator suspension, it is beneficial to improve the support strength of the radiator suspension while also improving the vibration isolation performance. However, no corresponding design scheme is proposed for integration and lightweight.

[0005] Therefore, it is of great significance to propose a vehicle radiator suspension that can be installed in a small space in a vehicle cabin in the art. Utility Model Content

[0010] Furthermore, the above-mentioned bushing suspension includes an inner sleeve, a rubber spring and a core shaft which are installed concentrically from the outside to the inside of the outer sleeve, and the radiator connection interface is a bolt hole three in the center of the core shaft.

[0011] Furthermore, the rubber spring has a transverse notch and a longitudinal notch.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1~Figure 5As shown, a vehicle radiator suspension includes a concentrically mounted bushing suspension 41 and an outer sleeve 42, wherein the outer sleeve 42 is connected to a mounting arm 43 extending radially toward the bushing suspension 41, one end of the mounting arm 43 has a frame connection interface, and the bushing suspension 41 has a radiator connection interface in the center.

[0026] When the vehicle radiator suspension provided in this embodiment is installed, the bushing suspension 41 is connected to the radiator to provide buffer support for the radiator. In this embodiment, the mounting arm 43 is integrally formed with the outer sleeve 42 and radially extends from the bushing suspension 41. The outer diameter of the mounting arm 43 gradually decreases from one end of the bushing suspension 41 to its end, so that the entire radiator suspension presents a horn shape. In this embodiment, the mounting arm 43 is a flat component as a whole, and has a frame connection interface thereon. When the mounting arm 41 is connected to the frame, the frame is used as a support point to provide buffer support for the radiator through the bushing suspension 41. Since the extended mounting arm 41 has a narrow and flat structural design relative to the mounting seat of the prior art, the mounting arm 41 can pass through the narrow space in the vehicle cabin. Therefore, its integration and lightweight are better than the radiator suspension of the prior art, and it can adapt to the narrow space installation in the cabin.

[0027] In a more preferred embodiment, Figure 1 and Figure 3 As shown, there are anti-collision beam connection interfaces on both sides of the jacket 42. After the radiator provided in this embodiment is connected to the vehicle frame and the radiator respectively, its position is relatively fixed, and at this time, the installation interface of the anti-collision beam is integrated into both sides of the jacket 42, so that the installation interface of the anti-collision beam can be integrated, further improving the integration degree of the radiator suspension.

[0028] In a more preferred embodiment, the anti-collision beam connection interface includes connection ears 421 arranged on both sides of the outer cover 42, and the connection ears 421 have waist holes 422. The anti-collision beam can be fixedly connected through the waist holes 422 opened by the connection ears 421. In this embodiment, the connection ears 421 are arranged in pairs, and the anti-collision beam can be fixedly installed through the connection ears 421.

[0029] In a more preferred embodiment, the frame connection interface includes a bolt hole 1 431 located in the middle of the mounting arm 43 , and a bolt hole 2 432 located at the bottom end of the mounting arm 43 . Figure 1A preferred implementation of the vehicle frame connection interface in this embodiment is shown. By inserting the fixing bolts through the bolt hole 1 431, the bolt hole 2 432 and the mounting hole reserved on the frame, the radiator suspension and the frame can be fixedly connected. The two mounting points are set in the middle of the mounting arm 43 and the bottom of the mounting arm 43. On the one hand, the double fixing interface improves the stability of the connection with the vehicle body, and on the other hand, it can optimize the impact torque transmitted to the radiator suspension during the vehicle's movement. In this embodiment, the area between the bolt hole 1 431 and the bolt hole 2 432 of the mounting arm 43 is hollowed out to form a support rib 1 435 with a certain angle. While being lightweight, the support rib 1 435 also provides a stable support with sufficient strength.

[0030] In a more preferred embodiment, the bushing suspension 41 includes an inner sleeve 44, a rubber spring 45 and a mandrel 46 which are installed concentrically from the outside to the inside of the outer sleeve 42, and the radiator connection interface is a bolt hole 3 461 in the center of the mandrel 46. The bolt hole 3 461 in the center of the mandrel 46 can be used to fix the radiator suspension and the heat sink by bolts. In this embodiment, the mandrel 46, the rubber spring 45 and the inner sleeve 44 are press-fitted into the outer sleeve 42 in sequence.

[0031] In a more preferred embodiment, the rubber spring 45 has a transverse notch 451 and a longitudinal notch 452. The transverse direction in this embodiment is a direction perpendicular to the vehicle's travel direction, and the longitudinal direction is the vehicle's height direction. When the vehicle nods, the rubber spring 45 in the radiator suspension needs to provide a certain longitudinal stiffness buffer support, and when the vehicle deflects, the rubber spring 45 in the radiator suspension needs to provide a certain transverse stiffness buffer support. The design of the transverse notch 451 and the longitudinal notch 452 can achieve stiffness adjustment in two directions by adjusting the corresponding notch sizes. The core shaft 46 and the outer sleeve 42 contact each other to provide greater support stiffness and provide a limit in this direction.

[0032] In a more preferred embodiment, the longitudinal notch 452 is larger than the transverse notch 451. Generally speaking, when the vehicle nods, the longitudinal load borne by the rubber spring 45 in the radiator suspension is relatively large, so in this embodiment, the longitudinal notch 452 is designed to be larger than the transverse notch 451, and when the longitudinal load of the vehicle is large, the larger longitudinal notch 452 is compressed.

[0033] In a more preferred embodiment, the bolt hole 461 has a positioning hole 462 on the side and the end face of the mandrel 46, and the positioning hole 462 has a positioning notch 463. After the bushing suspension 41 is fixed by the mandrel 46 and the heat dissipation connection, it needs to be positioned and limited to prevent the bushing suspension 41 from rotating after being fixed by the bolts. Therefore, the positioning hole 462 is designed as a limiting hole with a positioning notch 463. After the positioning notch 463 matches the fixed point on the heat dissipation, the rotation of the bushing suspension 41 can be limited. In this embodiment, the positioning notch 463 is designed as a fan-shaped notch.

[0034] In a more preferred embodiment, a cushion connection hole 433 is provided in the middle of the mounting arm 43, and a cushion positioning recess 434 is provided around the cushion connection hole 433. In this embodiment, in order to further improve the NVH performance of the vehicle and make the best use of the mounting and fixing position of the mounting arm 43, after the anti-collision beam is connected to the mounting arm 43 through its interface, the cushion can isolate the relative collision contact between the mounting arm 43 and the anti-collision beam. The cushion can be placed in the cushion positioning recess 434 and fixedly connected by bolts through the cushion connection hole 433. In this embodiment, the area of ​​the mounting arm 43 located at the cushion positioning recess 43 is hollowed out to form a support rib 2 436 with a certain angle, and the support rib 1 436 also provides a stable support with sufficient strength while being lightweight.

[0035] In a more preferred embodiment, the mandrel 46 is provided with a press-fitting hole 464, which is distributed in a circumference and has a press-fitting positioning hole 465. Since the mandrel 46 is assembled by a press-fitting process, the direction of its cylindrical shape is not fixed during press-fitting, and since the presence of the positioning hole 462 and the positioning notch 463 requires the mandrel 46 to be installed in a fixed direction during press-fitting, the press-fitting hole 464 and the press-fitting positioning hole 465 are designed, wherein the shape of the press-fitting positioning hole 465 is different from that of the press-fitting hole 464, and the angular direction positioning of the mandrel 46 during press-fitting can be achieved through the corresponding press-fitting tooling.
