Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical design, in particular to a transmission oil cooling pipe with a temperature control valve. Background Art

[0002] For pickup trucks equipped with AT transmissions, the temperature of the internal transmission oil will continue to rise when the transmission is working. When it rises to a certain high temperature, it will affect the normal operation of the transmission. Therefore, the transmission oil inside the transmission needs to be cooled by an oil cooler. The transmission oil inside the transmission needs to be transferred to the oil cooler through the oil cooling pipe and returned to the transmission after being cooled by the oil cooler.

[0003] Conventional oil cooling pipes only serve to connect the transmission and the oil cooler and cannot be installed on pickup trucks with limited space. The main problems are:

[0004] ① Conventional oil cooling pipes connect the gearbox and the oil cooler to achieve a simple gearbox oil cooling cycle, but cannot reasonably control the gearbox oil circulation through changes in gearbox oil temperature. When the gearbox oil temperature is low, there is no need to cool the gearbox oil inside the gearbox, but the conventional oil cooling pipe will still transmit the gearbox oil to the oil cooler, increasing the workload of the oil cooler and causing a waste of gearbox power.

[0005] ② Due to space limitations around the gearbox and oil cooler, conventional oil cooling pipes do not meet assembly requirements. This requires considering arranging the oil cooling pipes using a combination of hard pipes and soft pipes. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a transmission oil cooling pipe with a temperature control valve, which is used to solve the problem in the prior art that conventional oil cooling pipes cause transmission power waste.

[0007] To achieve the above-mentioned purpose and other related purposes, the technical solution of this utility model is as follows:

[0008] A transmission oil cooling pipe with a temperature control valve, comprising:

[0009] Transmission end oil cooling pipes, wherein two transmission end oil cooling pipes are arranged in parallel and both are connected to the transmission;

[0010] Oil cooling pipes at the oil cooler end, wherein two oil cooling pipes are arranged in parallel and both are connected to the oil cooler;

[0011] A temperature-controlled valve, comprising a first through hole and a second through hole, wherein a connecting through hole is provided between the first through hole and the second through hole;

[0012] The oil cooling pipe at the gearbox end, the first through hole, and the oil cooling pipe at the oil cooler end are connected in sequence, and the oil cooling pipe at the other gearbox end, the second through hole, and the oil cooling pipe at the other oil cooler end are connected in sequence; a temperature sensing valve is provided in one end of the oil cooling pipe section at the oil cooler end connected to the first through hole and the second through hole.

[0013] Optionally, both ends of the transmission end oil cooling pipe are hard pipes, and the middle part of the transmission end oil cooling pipe is a soft pipe.

[0014] Optionally, the oil cooling pipe at the oil cooler end includes a first pipe segment, a second pipe segment, a third pipe segment and a fourth pipe segment, wherein the first pipe segment and the third pipe segment are hard pipes, and the second pipe segment and the fourth pipe segment are soft pipes.

[0015] Optionally, the first pipe section is bent along the housing of the gearbox, and the first pipe section and the temperature control valve are fixed to the housing of the gearbox.

[0016] Optionally, the third pipe section is designed to be bent along the outside of the frame and is fixed to the frame.

[0017] Optionally, the end of the fourth pipe section adopts a quick-insert hose, and the quick-insert hose is used to be inserted into the oil cooler.

[0018] Optionally, the hose and the hard pipe are fixedly connected by a clamp.

[0019] Optionally, a first bracket is provided on the hard tube of the transmission end oil cooling pipe, and the first bracket is used to fix the transmission end oil cooling pipe.

[0020] Optionally, a second bracket is provided on the first pipe segment, and a third bracket is provided on the third pipe segment, and the second bracket and the third bracket are used to fix the oil cooling pipe at the oil cooler end.

[0021] Optionally, the temperature control valve is arranged on a temperature control valve bracket, the temperature control valve bracket is mounted on a housing of a gearbox, and the temperature control valve is provided with a bolt hole for fixedly connecting with the temperature control valve bracket.

[0022] In this utility model, a transmission oil cooling pipe with a temperature control valve is used to connect the transmission and the oil cooler. The temperature of the temperature control valve can be set to 75°C. When the transmission oil temperature within the automatic transmission does not exceed 75°C, the temperature-sensing valve in the temperature control valve closes, allowing the oil in the transmission to enter the second through-hole of the temperature control valve through the transmission-end oil cooling pipe. It then flows back into the transmission through the connecting hole, the first through-hole, and the other transmission-end oil cooling pipe. At this time, the oil in the transmission does not flow into the oil cooler. This process does not use the oil cooler, reducing the workload of the oil cooler and also reducing power loss in the transmission. When the transmission oil temperature within the automatic transmission exceeds 75°C, the temperature-sensing valve in the temperature control valve opens, allowing the oil in the transmission to enter the oil cooler through the transmission-end oil cooling pipe, the second through-hole, and the oil cooler-end oil cooling pipe. After cooling, the oil flows back into the transmission through the other oil cooler-end oil cooling pipe, the first through-hole, and the other transmission-end oil cooling pipe, thereby cooling the oil in the transmission. Compared with the existing technology, the structural coordination of the transmission oil cooling pipe, temperature control valve, and oil cooling pipe at the oil cooler end in this solution, as well as the temperature control valve's control of temperature, means that the oil in the transmission is only cooled by the oil cooler when the oil is at a high temperature, which reduces the workload of the oil cooler, improves cooling efficiency, reduces power loss in the transmission, and more reasonably controls the oil circulation route in the transmission.

[0031] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0032] It should be understood that the present invention can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided to make the disclosure thorough and complete and to fully convey the scope of the present invention to those skilled in the art. In the accompanying drawings, like reference numerals represent like components throughout.

[0033] The specific structure of the transmission oil cooling pipe with a temperature control valve 30 in the utility model is shown in FIG. Figures 1 to 4 ,include:

[0034] The transmission end oil cooling pipe 10, wherein two transmission end oil cooling pipes 10 are arranged in parallel and both are connected to the transmission;

[0035] Oil cooling pipes 20 at the oil cooler end, two of which are arranged in parallel and both are connected to the oil cooler;

[0036] The temperature control valve 30 includes a first through hole 31 and a second through hole 32 , wherein a connecting through hole is provided between the first through hole 31 and the second through hole 32 ;

[0037] The gearbox end oil cooling pipe 10, the first through hole 31, and the oil cooler end oil cooling pipe 20 are connected in sequence, and the other gearbox end oil cooling pipe 10, the second through hole 32, and the other oil cooler end oil cooling pipe 20 are connected in sequence; a temperature sensing valve is provided in one end of the first through hole 31 and the second through hole 32 connected to the oil cooler end oil cooling pipe 20.

[0038] Among them, another temperature-sensing valve can also be set at the connecting through hole, which is used in conjunction with the temperature-sensing valves in the first through hole 31 and the second through hole 32; the temperature-sensing valves at the two places can set the temperature of the temperature as needed. For example, in this solution, the temperature of the temperature-sensing valve can be set to 75°C, and can also be set to 50°C, 80°C, 100°C or other appropriate specific temperatures according to actual needs.

[0039] In actual implementation, when the transmission oil temperature inside the automatic transmission does not exceed 75°C, the temperature-sensing valves on the first through hole 31 and the second through hole 32 are both closed, and the temperature-sensing valve on the connecting hole is opened. The oil in the transmission enters the second through hole 32 of the temperature control valve 30 through the transmission-end oil cooling pipe 10, and then flows back into the transmission through the first through hole 31 and the other transmission-end oil cooling pipe 10 through the connecting hole. At this time, the oil in the transmission does not flow into the oil cooler. This process does not use the oil cooler, reducing the workload of the oil cooler and also reducing the power loss of the transmission. When the transmission oil temperature inside the automatic transmission exceeds 75°C, the temperature-sensing valves on the first through hole 31 and the second through hole 32 are both opened. The temperature-sensing valve on the connecting hole can be closed (or opened), and the oil in the transmission enters the oil cooler through the transmission-end oil cooling pipe 10, the second through hole 32, and the oil cooler-end oil cooling pipe 20. After cooling, the oil flows back into the transmission through the other oil cooler-end oil cooling pipe 20, the first through hole 31, and the other transmission-end oil cooling pipe 10, thereby cooling the oil in the transmission.

Figures 1 to 3 As shown, the fixing points of the first pipe segment 21 and the third pipe segment 24 can adopt hard pipes due to the relative movement, and the second pipe segment 23 adopts a soft pipe to prevent the oil cooling pipe from breaking due to the relative movement. The oil cooling pipe 20 at the oil cooler end adopts a combination of multiple sections of soft pipes and hard pipes to avoid interference with surrounding components, adapt to the spatial reality here, and improve the assembly performance of the oil cooling pipe 20 at the oil cooler end.

[0042] In some embodiments, the first pipe section 21 is bent along the housing of the gearbox, and the first pipe section 21 and the temperature control valve 30 are fixed to the housing of the gearbox. For example, Figures 1 to 3 As shown, the first pipe section 21 is bent mainly to fit the housing of the gearbox and facilitate connection with the temperature control valve 30.

[0043] In some embodiments, the third pipe section 24 is designed to be bent along the outside of the frame and fixed to the frame. Figures 1 to 3 As shown, in actual application, the third pipe section 24 is arranged at the frame position. Due to space limitations there, the third pipe section 24 can be designed to be a curved shape that fits the exterior of the frame.

[0044] In some embodiments, the end of the fourth pipe section 26 is a quick-insert hose, which is used to be inserted into the oil cooler. For example, Figures 1 to 3 As shown, it is convenient for the fourth pipe section 26 to be quickly connected to the oil cooler.

[0045] In some embodiments, the hose and the hard pipe are fixedly connected by a clamp 12. For example, Figures 1 to 3 As shown, the hose and the hard pipe are fixedly connected by a clamp 12, which can ensure the sealing of the connection.

[0046] In some embodiments, a first bracket 11 is provided on the hard tube of the transmission end oil cooling pipe 10, and the first bracket 11 is used to fix the transmission end oil cooling pipe 10. For example, Figures 1 to 3 As shown, the first bracket 11 facilitates fixing the hard tube of the gearbox end oil cooling tube 10 on the gearbox.

[0047] In some embodiments, a second bracket 22 is provided on the first pipe section 21, and a third bracket 25 is provided on the third pipe section 24. The second bracket 22 and the third bracket 25 are used to fix the oil cooling pipe 20 at the oil cooler end. For example, Figures 1 to 3 As shown, the second bracket 22 facilitates fixing the first pipe section 21 to the transmission in conjunction with the temperature control valve 30 , and the third bracket 25 facilitates fixing the third pipe section 24 to the vehicle frame.

[0048] In some embodiments, the temperature control valve 30 is provided on a temperature control valve bracket 33, and the temperature control valve bracket 33 is mounted on the housing of the gearbox. The temperature control valve 30 is provided with a bolt hole 34 for fixed connection with the temperature control valve bracket 33.
