Description

Technical Field

[0001] The utility model relates to the technical field of inner core tubes, in particular to the structure of an inner core tube of a low-noise and low-fuel-consumption gearbox. Background Art

[0002] The transmission inner core tube (also known as the transmission oil cooling tube or transmission oil line tube) is an important component in the automatic transmission system. The inner core tube is used to transmit transmission oil. The oil is pumped out of the transmission through the oil pump and sent to the cooler or radiator. After cooling, it returns to the transmission to ensure that the transmission maintains a suitable temperature during operation.

[0003] During the transmission process in the inner core tube, the transmission oil is not only cooled, but also effectively lubricates the various components inside the transmission, reducing friction and wear. However, the common inner core tube only cools itself during the cooling process, and lacks the function of dissipating heat and cooling the inner core tube body. During long-term use, the heat dissipation efficiency of the transmission oil will be reduced, which reduces the overall efficiency of the transmission and indirectly increases fuel consumption.

[0024] The utility model provides the following technical solutions:

[0025] Combine Figures 1 to 4 The structure of the inner core tube of the low-noise and low-fuel-consumption gearbox includes an inner core tube 1, and a heat dissipation mechanism 2 is provided on the outer side of the inner core tube 1;

[0026] The heat dissipation mechanism 2 includes a heat-conducting sleeve 26, which is movably connected to the outer wall of the inner core tube 1. The outer wall of the heat-conducting sleeve 26 is fixedly connected to a fixed frame 21, and the inner wall of the fixed frame 21 is fixedly connected to a fixed sleeve 23. A long block 24 is provided inside the fixed sleeve 23, and a positioning block 25 is fixedly connected to the back of the long block 24. The outer wall of the heat-conducting sleeve 26 is fixedly connected to heat dissipation fins 27, and the front of the positioning block 25 is rotatably connected to a threaded rod 22.

[0027] Furthermore, a through opening is provided on the outer side of the heat-conducting sleeve 26 , and the positioning block 25 is slidably connected to the inner wall of the through opening, so that the positioning block 25 can move through the through opening.

[0028] Furthermore, the inner side of the positioning block 25 is in close contact with the outer side of the inner core tube 1 , and the inner side of the positioning block 25 is provided with anti-slip grooves, so that the positioning block 25 can further press and limit the inner core tube 1 .

[0029] Furthermore, the inner wall of the fixing sleeve 23 matches the outer shape of the long block 24 , and the long block 24 is slidably connected to the inner wall of the fixing sleeve 23 , so that the positioning block 25 can move stably.

[0030] Furthermore, a torsion sleeve is fixedly connected to the front end of the fixing frame 21 , a threaded hole is provided on the front side of the fixing frame 21 , and the threaded rod 22 is threadedly connected to the inner wall of the threaded hole, so that the threaded rod 22 can rotate and move.

[0031] Furthermore, the inner core tube 1 includes a corrosion-resistant layer 11, the outer wall of the corrosion-resistant layer 11 is fixedly connected to a shock-absorbing layer 12, the outer wall of the shock-absorbing layer 12 is fixedly connected to a noise reduction layer 13, and the outer wall of the noise reduction layer 13 is fixedly connected to a protective layer 14, which further reduces the noise and vibration amplitude of the inner core tube 1 during operation.

[0033] In actual operation, when this device is used, the heat-conducting sleeve 26 is inserted into the outer wall of the inner core tube 1, and then the twist sleeve is rotated to drive the threaded rod 22 to rotate. Since the threaded rod 22 and the fixed frame 21 are threadedly connected, the rotational movement of the threaded rod 22 is converted into a linear movement of the positioning block 25, and the threaded rod 22 drives the positioning block 25 to move toward the outside of the inner core tube 1. When the inner side of the positioning block 25 is in close contact with the outer side of the inner core tube 1, the purpose of connecting the heat-conducting sleeve 26 can be achieved. During the operation of the inner core tube 1, the heat-conducting sleeve 26 can discharge the generated heat through the heat dissipation fins 27, and dissipate heat and cool the inner core tube 1.
