[0038] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0039] See Figures 1 to 8 The hydraulic actuator suspension system 100 of this embodiment includes a hydraulic actuator 1 and a suspension bracket 2. In this embodiment, the hydraulic actuator 1 can be a motor pump.

[0040] The hydraulic actuator 1 has at least three suspension connection portions 11, at least a portion of which are disposed adjacent to the end of the hydraulic actuator 1 along its length. Preferably, the number of suspension connection portions 11 can be three or four, thereby reducing the number of suspension brackets 2, reducing connection points, and lowering manufacturing difficulty and cost while ensuring the stability of the suspension structure.

[0041] The suspension connection portion 11 is provided near the end of the hydraulic actuator 1 in the length direction, thereby dispersing the multiple suspension connection portions 11 in the length direction and better arranging the multiple suspension connection portions 11 around the center of gravity of the hydraulic actuator 1, thereby improving the stability of the hydraulic actuator 1 after suspension.

[0042] The length direction of the hydraulic actuator 1 in this embodiment is generally the first direction shown in the figure.

[0043] The suspension bracket 2 has a first connecting portion 21 and a second connecting portion 22. The suspension bracket 2 is connected to the suspension connecting portion 11 via the first connecting portion 21, and the second connecting portion 22 is used to connect to the frame so that the hydraulic actuator 1 is suspended on the frame. Vibration isolation components 3 are provided at the first connecting portion 21 and / or the second connecting portion 22 of the suspension bracket 2. The suspension bracket 2 is positioned between the suspension connecting portion 11 on the hydraulic actuator 1 and the fixed position on the vehicle chassis to improve its adaptability to the chassis. The suspension bracket 2 can adjust the relative positions of the first connecting portion 21 and the second connecting portion 22 based on its own structural features, thereby ensuring that the first connecting portion 21 is aligned with the suspension connecting portion 11 and the second connecting portion 22 is aligned with the vehicle chassis. The vibration isolation components 3 can block the transmission of vibration, reduce radiated noise, and improve the user's riding experience.

[0044] In this embodiment, vibration isolation component 3 can be provided only at the first connecting part 21, or only at the second connecting part 22, thereby achieving primary vibration isolation. Of course, vibration isolation component 3 can also be provided at both the first connecting part 21 and the second connecting part 22, thereby achieving secondary vibration isolation.

[0045] The vibration isolation component 3 may include elastic components such as rubber components and spring components to avoid rigid connection between the suspension bracket 2 and the hydraulic actuator 1, and / or to the suspension bracket 2 and the vehicle body, so as to block the transmission of vibration to the vehicle body when the hydraulic actuator 1 vibrates.

[0046] The hydraulic actuator mounting system 100 of this utility model embodiment uses multiple mounting connection parts 11 distributed on the hydraulic actuator 1 to mount the hydraulic actuator 1. The position adjustment is more flexible, the stability of the hydraulic actuator 1 after mounting is better, and it can better take into account the forces of multiple degrees of freedom, effectively suppress the vibration of the hydraulic actuator 1, reduce radiated noise, and block the transmission of vibration to the vehicle body, which can effectively meet the NVH requirements of the whole vehicle.

[0047] like Figures 1 to 3 As shown, in some embodiments, there are multiple suspension brackets 2, and the multiple suspension brackets 2 correspond one-to-one with the suspension connection part 11 on the hydraulic actuator 1 and are connected to each other. The suspension bracket 2 includes a connecting block 23, and at least one of the first connecting part 21 and the second connecting part 22 is disposed on the connecting block 23.

[0048] And / or, at least one of the first connecting portion 21 and the second connecting portion 22 is a connecting lug 24 protruding from the side of the connecting block 23.

[0049] It is understandable that each suspension connection 11 is connected to a corresponding suspension bracket 2. The structure of the suspension bracket 2 at different suspension connection 11 can be different, so as to adjust the relative position of the first connection 21 and the second connection 22.

[0050] For example, in a partial suspension bracket 2, the connecting block 23 includes two connecting plates arranged in a generally L-shape, and a reinforcing plate is provided between the two connecting plates to improve the stability of the structure. The first connecting part 21 can be provided on one of the connecting plates, and the second connecting part 22 can be provided on the other connecting plate.

[0051] For example, in some suspension brackets 2, the connecting block 23 is generally rectangular, with a connecting lug 24 at one end of the rectangular block, extending away from the rectangular block. A second connecting portion 22 is disposed on the rectangular block, and the connecting lug 24 is constructed as a first connecting portion 21. This allows adjustment of the relative positions of the first connecting portion 21 and the second connecting portion 22 to ensure that the first connecting portion 21 is aligned with the suspension connecting portion 11 of the hydraulic actuator 1, and the second connecting portion 22 is aligned with the fixed position on the vehicle chassis. Simultaneously, it enables precise positioning of the hydraulic actuator 1, resulting in better chassis adaptability.

[0052] This embodiment can meet the space installation requirements of different vehicle models by adjusting the relative positions of the first connecting part 21 and the second connecting part 22 in different suspension brackets 2, thus improving its practicality.

[0053] like Figures 4 to 6 As shown, in some embodiments, there is one suspension bracket 2, which has multiple first connecting parts 21 and multiple second connecting parts 22. The multiple first connecting parts 21 correspond one-to-one with the suspension connecting parts 11 on the hydraulic actuator 1 and are connected to each other. The suspension bracket 2 has a receiving groove, and part of the hydraulic actuator 1 is disposed in the receiving groove.

[0054] The suspension bracket 2 can be an integral stamped or cast structure. The suspension bracket 2 can cover the outer side of a section of the hydraulic actuator 1, thereby making the multiple first connecting parts 21 arranged on the suspension bracket 2 correspond one-to-one with the multiple suspension connecting parts 11 on the hydraulic actuator 1 and connect them together.

[0055] The suspension bracket 2 can be designed with a hollow structure to reduce its weight and material consumption. At the same time, it can provide a channel for external connection components such as control cables and hydraulic lines of the hydraulic actuator 1, so as to avoid interference between the suspension bracket 2 and external connection components.

[0056] In this embodiment of the present invention, the suspension bracket 2 can fit more closely with the hydraulic actuator 1, and the second connecting part 22 on the suspension bracket 2 is more flexible, making it easier to install and more stable.

[0057] In some embodiments, the hydraulic actuator 1 includes a first motor housing 12 and a first pump housing 13. The first pump housing 13 is disposed at one end of the first motor housing 12 along its length. At least three suspension connection portions 11 are partially disposed on the first pump housing 13 or on one end of the first motor housing 12 adjacent to the first pump housing 13. The other part of the at least three suspension connection portions 11 is disposed on one end of the first motor housing 12 away from the first pump housing 13.

[0058] In this embodiment, the hydraulic actuator 1 is a motor pump, which includes a motor and a pump connected together. Of course, the motor pump also includes a controller housing 17, which can be connected to the first motor housing 12, thereby forming a three-in-one motor pump consisting of a motor, a pump and a controller.

[0059] In this embodiment, the first direction, the second direction, and the third direction are orthogonal to each other, and the controller housing 17 and the first motor housing 12 are stacked in the generally third direction shown in the figure.

[0060] Optionally, see Figures 4 to 6 There are three suspension connection parts 11. The first suspension connection part 11 is located at the end of the first pump housing 13 away from the first motor housing 12, and the second and third suspension connection parts 11 are located at the ends of the first motor housing 12 away from the first pump housing 13. The second and third suspension connection parts 11 are arranged substantially symmetrically in the second direction. Simultaneously, the first suspension connection part 11 is adjacent to the third-direction upward side of the hydraulic actuator 1, and the second and third suspension connection parts 11 are adjacent to the other third-direction upward side of the hydraulic actuator 1. This improves stability.

[0061] Optionally, see Figure 7 There are four suspension connection parts 11. Two suspension connection parts 11 are located at one end of the first motor housing 12 adjacent to the first pump housing 13, and two suspension connection parts 11 are located at the end of the first motor housing 12 away from the first pump housing 13. The two suspension connection parts 11 located at the same end of the first motor housing 12 are arranged substantially symmetrically in the second direction.

[0062] In some embodiments, the hydraulic actuator 1 includes a second motor housing 14, a second pump housing 15, and a third pump housing 16. The second pump housing 15 is disposed at a first end in the length direction of the second motor housing 14, and the third pump housing 16 is disposed at a second end in the length direction of the second motor housing 14. At least three suspension connection portions 11 are partially disposed in the second pump housing 15 or at one end of the second motor housing 14 adjacent to the second pump housing 15, and other portions of the at least three suspension connection portions 11 are disposed in the third pump housing 16 or at one end of the second motor housing 14 adjacent to the third pump housing 16.

[0063] In this embodiment, the hydraulic actuator 1 is a motor pump, which includes two motors and two pumps. Both motors are housed in the second motor housing 14, which can be a separate structure or an integrated structure. The motor pump also includes a controller housing 17, which can be connected to the second motor housing 14, thus forming a five-in-one motor pump consisting of two motors, two pumps, and a controller.

[0064] Optionally, see Figures 1 to 3 There are three suspension connection parts 11. One suspension connection part 11 is located at the end of the second pump housing 15 away from the second motor housing 14, one suspension connection part 11 is located at the end of the third pump housing 16 away from the second motor housing 14, and one suspension connection part 11 is located in the middle of the second motor housing 14. The suspension connection part 11 located in the middle of the second motor housing 14 is located on one side of the second direction of the second motor housing 14.

[0065] Optionally, see Figure 8 There are four suspension connection parts 11. The first suspension connection part 11 is located at the end of the second pump housing 15 away from the second motor housing 14. The second suspension connection part 11 is located at the end of the third pump housing 16 away from the second motor housing 14. The third and fourth suspension connection parts 11 are located in the middle of the length direction of the second motor housing 14, and the third and fourth suspension connection parts 11 are arranged symmetrically in the second direction.

[0066] In some embodiments, the center of mass of the hydraulic actuator 1 is adjacent to the center of the triangle formed by the centers of the three suspension connections 11. This ensures better overall structural stability, allowing the multiple suspension connections 11 to distribute the force more reasonably and evenly to the vehicle body through the multiple suspension brackets 2 when the suspended hydraulic actuator 1 vibrates, thus preventing the center of gravity of the hydraulic actuator 1 from shifting due to unreasonable suspension point positions, which would affect the stability of the suspension system.

[0067] Furthermore, the centers of at least three suspension connections 11 are located within the first plane, and the center of mass of the hydraulic actuator 1 is located on the first plane. This further improves the stability of the suspension system.

[0068] In this embodiment, multiple suspension connection parts 11 are arranged around the center of mass of the hydraulic actuator 1, which can improve the stability and practicality of the suspension system, making it more stable during vehicle operation, with low radiated noise, good vibration isolation performance, balanced force distribution, and long service life of each suspension part.
