Description

Technical Field

[0001] This utility model relates to the field of vibration damper technology, specifically to an active vibration damper oil cooling device. Background Technology

[0002] In active suspension technology, active adjustment is achieved through active dampers. By adjusting the amount of oil in the working cylinder of the active damper through an external hydraulic pump, the piston rod of the damper moves, thereby adjusting the vehicle height.

[0003] During the aforementioned process, the hydraulic pump outputs hydraulic oil with a certain high pressure. Simultaneously, a significant amount of heat generated by the motor within the pump is transferred to the shock absorber via the pipeline, causing the hydraulic oil temperature inside the shock absorber to become excessively high. Furthermore, the hydraulic oil temperature also rises significantly during the high-speed movement of the shock absorber piston, leading to a substantial decrease in the viscosity of the hydraulic oil inside the shock absorber, cavitation, and accelerated oil aging, resulting in a decline in the working efficiency of the active shock absorber. This also reduces the lubrication performance of the hydraulic oil, accelerating the wear of important hydraulic components such as the hydraulic pump and valve system. Additionally, excessively high oil temperature can cause aging of rubber seals, leading to system leaks and even system malfunctions. Utility Model Content

[0004] The technical problem to be solved by this invention is how to achieve heat dissipation of the active damper oil.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An active damper oil cooling device includes a radiator body and cooling fins; The radiator body has an oil inlet channel and an oil outlet channel arranged along its length, and multiple heat dissipation fins are circumferentially connected to the outer wall of the radiator body. The heat dissipation fins include a main fin and two support fins. One end of the main fin is connected to the outer wall of the heat dissipation body, and the other end is arranged along the radial direction of the heat dissipation body and connected to the two support fins to form a Y-shaped fin structure.

[0006] The radiator body and cooling fins cool the hot oil in the oil pipes, ensuring that the oil entering the active damper is low-temperature oil. This effectively cools the active damper oil and suppresses a series of problems such as reduced working efficiency and accelerated failure caused by excessively high oil levels inside the active damper.

[0008] Preferably, the inner diameter of the oil inlet channel and the oil outlet channel is not less than 8.9 mm.

[0011] Preferably, it also includes two sets of hydraulic connectors that can be snapped onto both ends of the radiator body. The hydraulic connectors include a connector body and two pipes. The connector body has a recessed interface. Inside the interface, there are two through holes that correspond to the oil inlet channel and the oil outlet channel. The interface is snapped onto the end of the radiator body. Each through hole is connected to a pipe at the end away from the radiator body.

[0012] Preferably, a sealing ring is provided in the interface for sealing the through holes of the oil inlet channel and the oil outlet channel.

[0013] Preferably, a connector body is also provided on the outer wall of the connector body for connecting the radiator body.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The radiator body and cooling fins cool the hot oil in the oil pipes, ensuring that the oil entering the active damper is low-temperature oil. This effectively cools the active damper oil and suppresses a series of problems such as reduced working efficiency and accelerated failure caused by excessively high oil levels inside the active damper.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0018] In this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0019] See Figure 1 This embodiment discloses an active damper oil cooling device, including a radiator body 1, cooling fins 2 and a hydraulic connector 3.

[0020] See Figure 2 The radiator body 1 has parallel oil inlet channels 11 and oil outlet channels 12 arranged along its length for oil flow. Multiple heat dissipation fins 2 are circumferentially connected to the outer wall of the radiator body 1. Hydraulic connectors 3 are snapped onto both ends of the radiator body 1. In this embodiment, the oil inlet channels 11 and oil outlet channels 12 are integrated into the same radiator body 1, which significantly reduces the assembly difficulty of the heat dissipation device and improves its stability.

[0021] Furthermore, the inner diameter of the oil inlet channel 11 and the oil outlet channel 12 is not less than 8.9 mm, and the roughness of the two oil channels is not greater than Ra3.2.

[0022] See Figure 3 The heat dissipation fins 2 include a main fin 21 and two supporting fins 22. One end of the main fin 21 is connected to the outer wall of the radiator body 1, and the other end is arranged along the radial direction of the radiator body 1 and connected to the two supporting fins 22 to form a Y-shaped fin structure. By setting the Y-shaped heat dissipation fins 2, the heat dissipation area is increased. Most of the heat in the oil is transferred to the heat dissipation fins 2 through the radiator body 1, and then dissipated into the air through the heat dissipation fins 2, which improves the heat dissipation effect of the oil inlet channel 11 and the oil outlet channel 12 inside the radiator body 1, and realizes rapid heat dissipation of the oil.

[0023] Furthermore, the spacing between adjacent main fins 21 is not less than 4mm, the included angle between the two support fins 22 on each heat dissipation fin 2 is not less than 25°, the distance between the end of each support fin 22 away from the main fin 21 and the heat sink body 1 is 30mm, and the thickness of the support fin 22 is 2mm.

[0024] See Figure 4The hydraulic connector 3 includes a connector body 31, two pipes 32, and a connecting seat 33. The connector body 31 has a recessed interface 311 with two through holes 312 inside. The interface 311 is snapped onto the end of the radiator body 1, such that each through hole 312 is connected to the oil inlet channel 11 and the oil outlet channel 12. The end of each through hole 312 furthest from the radiator body 1 is connected to a pipe 32. The pipes 32 are used to connect to the oil pipes on the active shock absorber and the hydraulic pump. In this embodiment, the pipes 32 are rigid pipes for easy connection to the oil pipes.

[0025] A sealing ring (not shown in the figure) is provided in the interface 311 for sealing the through hole 312 of the oil inlet channel 11 and the through hole 312 of the oil outlet channel 12.

[0026] The outer wall of the connector body 31 is also provided with a connecting seat 33 for connecting the radiator body 1, and the radiator body 1 is fixedly connected by bolts through the connecting seat 33.

[0027] The working principle of this embodiment is as follows: First, two hydraulic connectors 3 are snapped onto the two ends of the radiator body 1, and fixedly connected to the radiator body 1 by bolts through the connecting seat 33. Then, the oil pipes on the active damper and the oil pipes on the hydraulic pump are connected to the through hole 312 to realize the cyclic connection between the active damper, the oil pipes and the hydraulic pump.

[0028] When the active damper and hydraulic pump are working, the hot oil in the active damper flows into the oil inlet channel 11 through the oil pipe and pipe 32. The hot oil is cooled by the radiator body 1 and the heat dissipation fins 2. After being cooled, the oil flows out of the radiator body 1 and is circulated by the hydraulic pump before flowing into the oil outlet channel 12. Then, it enters the active damper through pipe 32 and oil pipe for circulation.

[0029] During the above cycle, the radiator body 1 and the heat dissipation fins 2 cool the hot oil in the oil pipe, so that the oil entering the active damper is low temperature oil, thereby achieving heat dissipation of the active damper oil and effectively suppressing a series of problems such as reduced working efficiency and accelerated failure caused by excessive oil temperature inside the active damper.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
