Description

有动液温度自动调节装置的液力变矩器 技术领域  Hydraulic torque converter with automatic liquid temperature adjustment device
[0001 ]本发明涉及一种汽车传动装置液力变矩器。 背景技术  [0001] The present invention relates to an automotive transmission torque converter. Background technique
[0002] 液力变矩器是一种用动液传动并调节转矩的汽车传动装置。 在使用过程中，动液 的温度会升高，从而影响转矩的传送，影响液力变矩器的输出。为此，在使用过程中，当动液 温度升高时，需将动液输送到降温器对动液降温。 已有技术美国专利 US 7, 487, 826B2 《旁 通闽及热交换器》，公布了一种有由动液温度控制的旁通闽的热交换器。 在动液为低温时， 旁通闽关闭油路，动液不通过热交换器；当动液温度升高到一定值时，旁通闽动作，将油路 打开，使动液通过热交换器降温，从而保持液力变矩器内动液温度为低温，使液力变矩器正 常工作。 已有技术不足之处是，感受动液温度的旁通闽，距液力变矩器较远，不能准确反映 动液的温度动作，使液力变矩器的输出受到影响。 发明内容  [0002] A torque converter is an automotive transmission that uses hydraulic fluid to drive and adjust torque. During use, the temperature of the moving liquid will rise, which will affect the transmission of torque and affect the output of the torque converter. For this reason, during use, when the temperature of the moving liquid rises, the moving liquid is sent to the desuperheater to cool the moving liquid. Prior art U.S. Patent No. 7,487,826 B2, "Bypass and Heat Exchanger", discloses a heat exchanger having a bypass enthalpy controlled by a liquid-liquid temperature. When the moving liquid is at a low temperature, the bypass 闽 closes the oil passage, and the moving liquid does not pass through the heat exchanger; when the temperature of the moving liquid rises to a certain value, the bypass 闽 moves to open the oil passage, and the moving liquid passes through the heat exchanger. Cool down, so as to keep the temperature of the fluid in the torque converter low, so that the torque converter works normally. The shortcoming of the prior art is that the bypass enthalpy of the temperature of the kinetic fluid is far from the torque converter, and the temperature action of the kinetic fluid cannot be accurately reflected, so that the output of the torque converter is affected. Summary of the invention
[0003] 所要解决的技术问题是，提供一种装在靠近液力变矩器的动液进出口处的有动液 温度自动调节装置的液力变矩器。  [0003] A technical problem to be solved is to provide a torque converter having an automatic liquid temperature automatic adjusting device installed at an inlet and outlet of a hydrodynamic fluid close to a torque converter.
[0004] 解决其技术问题的技术方案，包含液力变矩器、温度控制闽及散热器；液力变矩器 上有动液出口管及动液进口管，动液进口管及动液出口管与散热器连接；温度控制闽装在 靠近液力变矩器动液进口管、动液出口管端处.。  [0004] The technical solution for solving the technical problem thereof comprises a hydraulic torque converter, a temperature control device and a radiator; the hydraulic torque converter has a liquid liquid outlet pipe and a moving liquid inlet pipe, a moving liquid inlet pipe and a liquid and liquid outlet The tube is connected with the radiator; the temperature control is installed near the hydrodynamic inlet tube and the liquid outlet tube end of the hydraulic torque converter.
[0005] 温度控制闽包含闽体、闽芯、弹簧、活塞杆座及活塞杆；闽芯、弹簧及活塞杆座装在 闽体内，闽芯中孔有活塞杆腔，活塞杆腔内装热敏橡胶，活塞杆与活塞杆座连接为一体，活 塞杆下段装入闽体的活塞杆腔内，可在其中滑动，活塞杆的下端与热敏橡胶的上端面接触； 闽体上有闽体进口及闽体出口，闽体进口与液力变矩器的动液出口管连接，闽体出口与液 力变矩器的动液进口管连接。  [0005] The temperature control device comprises a body, a core, a spring, a piston rod seat and a piston rod; the core, the spring and the piston rod seat are mounted in the body, the piston hole has a piston rod cavity, and the piston rod cavity is filled with heat. The rubber, the piston rod and the piston rod seat are integrally connected, and the lower part of the piston rod is inserted into the piston rod cavity of the body, and can slide therein, and the lower end of the piston rod is in contact with the upper end surface of the heat-sensitive rubber; And the carcass outlet, the carcass inlet is connected with the hydrodynamic outlet pipe of the hydraulic torque converter, and the carcass outlet is connected with the hydrodynamic inlet pipe of the hydraulic torque converter.
[0006] 在动液温度为低温时，闽芯内的热敏橡胶感受低温的动液温度，体积较小，闽芯在 弹簧弹力作用下上移，使闽体进口与闽体出口连通，液力变矩器的动液由动液出口管经温 度控制闽的闽体进口、闽体出口及动液进口管直接流回液力变矩器，而不经过散热器，动液 保持低温；在动液温度为高温时，闽芯内的热敏橡胶感受高温的动液温度，体积增大，流体 推动闽芯移动到下位，闽芯将闽体进口与闽体出口间通道关闭，使液力变矩器的动液不能 通过温度控制闽回流，此时动液由动液出口管流入散热器，经散热器降温后，由动液进口管 流回液力变矩器，使动液保持低温，从而保证液力变矩器正常工作。  [0006] When the temperature of the liquid is low, the temperature-sensitive rubber in the core feels the temperature of the moving liquid at a low temperature, and the volume is small, and the core moves up under the action of the spring force, so that the inlet of the body is connected with the outlet of the body, and the liquid The dynamic fluid of the torque converter is directly returned to the hydraulic torque converter by the temperature control 闽 of the 闽 body inlet, the 闽 body outlet and the kinetic fluid inlet pipe, without passing through the radiator, and the liquid and liquid remains at a low temperature; When the temperature of the liquid is high, the temperature of the thermosensitive rubber in the core feels the temperature of the high temperature, and the volume increases. The fluid pushes the core to the lower position, and the core closes the passage between the inlet of the body and the outlet of the body to make the hydraulic force. The fluid of the torque converter cannot be returned by the temperature control. At this time, the moving liquid flows into the radiator from the moving liquid outlet pipe. After the radiator is cooled, the fluid inlet pipe flows back to the hydraulic torque converter to keep the liquid and liquid low. To ensure that the torque converter works properly.
[0007] 有益效果： 本发明结构应用于汽车液力变矩器的有益效果是，温度控制闽装在靠近 液力变矩器的进出口管端，直接感受液力变矩器内动液的温度，保证液力变矩器的正常工 作。 附图说明 [0008] 图 1为本发明实施例的结构图。 图 1中， 1为液力变矩器，2为温度控制闽，3为散热 器， 4为动液出口管，5为动液进口管，6为闽体，7为闽芯，8为弹簧，9为活塞杆座， 10为活塞 杆， 11为活塞杆腔， 12 热敏橡胶， 13为闽体进口， 14为闽体出口。 具体实施方式 [0007] Advantageous Effects: The utility model has the beneficial effects that the structure is applied to an automobile torque converter, that the temperature control is installed close to the inlet and outlet pipe end of the hydraulic torque converter, and directly feels the dynamic liquid in the hydraulic torque converter.
