Abstract
Description
Technical Field
[0001] This utility model relates to the field of transmission structure technology, and in particular to a hydraulic torque converter that facilitates the replacement of cooling oil. Background Technology
[0002] The torque converter is a commonly used power transmission structure in vehicles. It is positioned between the reducer and the engine, avoiding direct contact between the two transmission structures. This results in smoother gear shifts and eliminates noticeable jerkiness during gear changes, improving the driving experience. However, the torque converter has a drawback: its power transmission efficiency is relatively low. Compared to traditional power transmission mechanisms, more mechanical energy is converted into the internal energy of the fluid, leading to energy waste. Therefore, to improve the useful power output of the engine, existing technologies incorporate a clutch mechanism within the torque converter. When the engine speed is stable, this allows the turbine and pump impeller to make hard contact, thus improving the efficiency of mechanical energy transmission. However, existing clutch mechanisms are relatively complex and usually require computer-controlled engagement, resulting in higher usage and maintenance costs. Utility Model Content
[0003] The purpose of this invention is to provide a hydraulic torque converter that facilitates the replacement of cooling oil, thereby solving the problems existing in the prior art.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A hydraulic torque converter that facilitates cooling oil replacement includes a hydraulic torque converter body and a clutch. The hydraulic torque converter body is provided with a medium inlet and a medium outlet. The medium inlet is connected to the medium outlet through a pipe. The pipe includes a first semi-circular shell and a second semi-circular shell. The first and second semi-circular shells form an annular hollow shell structure. The centrifugal sides of both the first and second semi-circular shells are provided with arc transition angles. The first semi-circular shell is provided with a collection port corresponding to the medium inlet and a drain port corresponding to the medium outlet. The second semi-circular shell is provided with a suction port and an injection port.
[0005] By adopting the above technical solution, the collection port and drain port on the first housing are used to cooperate with the medium inlet and medium outlet of the hydraulic torque converter body to circulate the ATF oil inside the hydraulic torque converter, and the suction port and injection port on the second semi-circular housing are used to replace the ATF oil during use.
[0006] In a further embodiment, the suction port is connected to the interior of the oil tank via a first hose, and the injection port is connected to the interior of the oil tank via a second hose. The interior of the oil tank is equipped with a filter and a hydraulic pump. The hydraulic pump is used to inject cooling oil into the interior of the second semi-circular housing in cooperation with the second hose. A solenoid valve is installed on the pipeline.
[0007] By adopting the above technical solution, the ATF oil will rise in temperature during use due to the conversion of mechanical energy into internal energy. Therefore, it is necessary to pay attention to the temperature of the ATF oil in real time to keep it at the optimal working temperature. Thus, it is necessary to use a fuel tank to replace it at a fixed flow rate.
[0008] In a further embodiment, the interior of the oil tank is provided with cooling pipes for cooling the interior of the oil tank.
[0009] By adopting the above technical solution, the temperature of the ATF oil stored inside the oil tank can be further controlled.
[0010] In a further embodiment, the clutch is sleeved on one end of the hydraulic torque converter body. The clutch includes a gear ring, a slider, and a sleeve. An external gear is sleeved on one end of the hydraulic torque converter body. A slider is slidably mounted on each tooth of the external gear, and the gear ring is sleeved on the slider.
[0011] By adopting the above technical solution, the sliding effect of the gear ring along the axial direction can be achieved through the cooperation of the slider and the gear ring, thereby controlling the clutch.
[0012] In a further embodiment, a partition is provided inside the second semi-circular housing to separate the suction port and the injection port.
[0013] By adopting the above technical solution, the suction port is prevented from sucking the newly injected oil back into the oil tank.
[0014] In summary, this utility model has the following beneficial effects: 1. The collection port and drain port on the first housing are used to cooperate with the medium inlet and medium outlet of the hydraulic torque converter body to circulate the ATF oil inside the hydraulic torque converter. The suction port and injection port on the second semi-circular housing are used to replace the ATF oil during use. Attached Figure Description

[0019] Example 1: like Figures 1-2 As shown, a hydraulic torque converter for easy cooling oil replacement includes a hydraulic torque converter body 1 and a clutch 2. The hydraulic torque converter body 1 is provided with a medium inlet and a medium outlet. The medium inlet is connected to the medium outlet through a pipe. The pipe includes a first semi-circular shell 3 and a second semi-circular shell 4. The first semi-circular shell 3 and the second semi-circular shell 4 form an annular hollow shell structure. The centrifugal side edges of the first semi-circular shell 3 and the second semi-circular shell 4 are provided with arc transition angles. The first semi-circular shell 3 has a collection port corresponding to the medium inlet and a drain port corresponding to the medium outlet. The second semi-circular shell 4 has a suction port and an injection port. The suction port is connected to the inside of the oil tank 5 via a first hose, and the injection port is connected to the inside of the oil tank 5 via a second hose. The inside of the oil tank 5 is equipped with a filter and a hydraulic pump. The hydraulic pump is used to inject cooling oil into the inside of the second semi-circular housing 4 in cooperation with the second hose. A solenoid valve is installed on the pipeline. The inside of the oil tank 5 is equipped with a cooling pipeline for cooling the inside of the oil tank 5. The clutch 2 is sleeved on one end of the hydraulic torque converter body 1. The clutch 2 includes a gear ring, a slider and a sleeve. An external gear is sleeved on one end of the hydraulic torque converter body 1. A slider is slidably installed on each tooth of the external gear. The gear ring is sleeved on the slider. The inside of the second semi-circular housing is equipped with a partition for separating the suction port and the injection port.
[0020] Specific implementation process: The collection port and drain port on the first housing are used to cooperate with the medium inlet and medium outlet of the hydraulic torque converter body to circulate the ATF oil inside the hydraulic torque converter. The suction port and injection port on the second semi-circular housing are used to replace the ATF oil during use.
[0021] The hydraulic torque converter mainly comprises a hydraulic torque converter body 1 and a clutch 2. The hydraulic torque converter body 1 has a medium inlet and a medium outlet, which are connected by an annular pipe. This pipe is formed by the mating of a first semi-circular shell 3 and a second semi-circular shell 4, creating a hollow annular structure. The centrifugal edges of both semi-circular shells are designed with rounded transition angles to improve fluid flow performance and reduce eddies and resistance.
[0022] The first semi-circular housing 3 has two openings: one is a collection port corresponding to the medium inlet, used to receive the high-temperature oil flowing out of the hydraulic torque converter; the other is a drain port corresponding to the medium outlet, used to send the cooled oil back into the hydraulic torque converter to achieve oil circulation cooling. The second semi-circular housing 4 is provided with a suction port and an injection port, which are arranged opposite each other for replacing the ATF automatic transmission fluid during system operation.
[0023] To facilitate oil replacement and purification, the suction port is connected to the inside of the oil tank 5 via a first hose, while the injection port is also connected to the oil tank 5 via a second hose. The oil tank contains a filter and a hydraulic pump. The hydraulic pump, in conjunction with the second hose, injects filtered and cooled new oil into the second semi-circular housing 4. A solenoid valve is also installed on the first hose to control the start / stop of the suction process and the flow rate.
[0024] The oil tank 5 is also equipped with cooling pipes to provide auxiliary cooling for the stored ATF oil, ensuring that the oil temperature is always within a suitable operating range and further improving the system's thermal management performance. In addition, the second semi-circular shell 4 has a baffle inside to separate the suction area from the injection area, preventing newly injected oil from being immediately drawn back into the oil tank and ensuring the effectiveness of oil replacement.
[0025] The clutch 2 part is fitted onto one end of the hydraulic torque converter body 1, and its structure includes a gear ring, a slider, and a sleeve. An external gear is mounted at the end of the hydraulic torque converter body 1, with a slider slidably mounted on each tooth, and the gear ring is fitted over the slider. Through the cooperation between the slider and the gear ring, the gear ring can slide along the axial direction, thereby controlling the switching of the clutch state. This mechanical clutch structure simplifies the control logic and reduces system complexity and maintenance costs.
[0026] During actual operation, the ATF oil inside the hydraulic torque converter heats up due to power transmission. The high-temperature oil flows out through the medium outlet and enters the annular pipe through the collection port of the first semi-circular shell 3. As the oil flows in the pipe, some heat is dissipated through the shell, while the suction port on the second semi-circular shell 4 draws some oil into the oil tank 5. After filtration and cooling, the oil is pumped back to the injection area by the hydraulic pump, completing the real-time renewal and circulating cooling of the oil.
[0027] This design not only achieves continuous cooling and filtration of the oil, but also enables oil replacement during operation without downtime, significantly improving system reliability and service life. Furthermore, its modular, semi-circular casing facilitates manufacturing, installation, and maintenance, offering strong practicality and economy.
[0028] In summary, this utility model, by optimizing the pipeline structure and oil circuit design, and combining an external oil tank and a filtration and cooling system, achieves efficient circulation and convenient replacement of the hydraulic torque converter cooling oil, thereby improving the working efficiency and reliability of the transmission system. It is especially suitable for vehicle transmission devices operating under high loads or continuous operation.
