The transmission assembly refers to the complete combination of the entire gearbox, including clutch plate, speed gear, gearbox body, one, two, three shafts, one, two, three, four, five gears, driving gear, synchronizer, reverse gear, shift fork, shift fork shaft and bearings. The transmission assembly is an indispensable component in the automobile. It can change the transmission ratio and movement direction to enable the car to achieve different driving states under different driving conditions.

[0003] In actual car use, the transmission assembly plays a very important role. The driver operates the clutch and the shift lever to achieve the meshing of different gears, thereby changing the transmission ratio and achieving the purpose of shifting. However, the transmission will generate heat due to rotation friction when working. Traditional transmissions are relatively closed, so the heat cannot be dissipated well, causing the mechanical parts in the transmission to be in a high temperature state for a long time and easily damaged, resulting in the transmission not being able to work properly. In addition, the transmission will generate continuous noise when running, which will make people feel uncomfortable for a long time. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only examples of the present invention.

[0021] Some embodiments, but not all embodiments, are based on the embodiments in the utility model. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-Figure 4 A protective structure for the outer side of a gearbox assembly includes a gearbox body 1, an outer wall of the gearbox body 1 is provided with a sound insulation protection shell 2, a mounting seat 3 is fixedly connected to the bottom end of the outer wall of the sound insulation protection shell 2, both sides of the outer wall of the mounting seat 3 are fixedly connected with evenly distributed connecting ribs 4, the outer wall of the mounting seat 3 is fixedly connected with evenly distributed connecting blocks 5, a heat dissipation port 6 is opened inside the mounting seat 3, and a heat dissipation component 7 is arranged in the heat dissipation port 6.

[0023] It should be noted that the transmission body 1, the silencer cotton layer 21, the refrigeration device 71, the intake fan 74, and the exhaust fan 75 are all existing technologies. The specific model specifications need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be repeated.

[0024] Furthermore, the sound insulation protective shell 2 is composed of a sound-absorbing cotton layer 21, an inner protective plate 22, a spacer block 23, an outer protective plate 24, and air holes 25. The sound-absorbing cotton layer 21 is wrapped on the outer wall of the transmission body 1, and the inner protective plate 22 is arranged on the outer wall of the sound-absorbing cotton layer 21. The spacer blocks 23 are evenly distributed and fixedly connected to the outer wall of the inner protective plate 22.

[0025] The function of the sound insulation protective shell 2 is to absorb and block part of the noise generated by the transmission body 1 during operation through the sound-absorbing cotton layer 21, and the remaining part of the noise is completely isolated under the action of the spacing layer.

[0026] Furthermore, the outer protective plate 24 is fixedly connected to the outer wall of the spacer block 23 facing outwards, and the air holes 25 are arranged on the outer wall of the spacer block 23 .

[0027] Among them, under the action of the air holes 25 set on the spacer block 23, the cold air input between the inner protective plate 22 and the outer protective plate 24 can be evenly distributed in the entire space, making the heat dissipation more uniform.

[0028] Furthermore, the bottom ends of the mounting seat 3 and the connecting block 5 are fixedly connected with a shock-absorbing rubber pad 8 , and the outer wall of the connecting block 5 is provided with a threaded hole 9 .

[0029] Among them, under the action of the shock-absorbing rubber pad 8, the vibration generated by the transmission body 1 during operation can be alleviated, which can reduce the impact of vibration and impact on the transmission. The shock-absorbing rubber pad 8 usually has good elasticity and durability and can maintain its shock-absorbing effect for a long time.

[0030] Furthermore, the heat dissipation assembly 7 includes a refrigeration device 71, an insulation box 72, a cooling coil 73, an intake fan 74, and an exhaust fan 75. The refrigeration device 71 is arranged at the bottom end of the inner wall of the heat dissipation port 6, the insulation box 72 is fixedly connected to the cold air outlet of the refrigeration device 71, the cooling coil 73 is arranged inside the insulation box 72, the intake fan 74 is connected to the outer wall of one side of the sound insulation protective shell 2, and the exhaust fan 75 is connected to the other side of the sound insulation protective shell 2.

[0031] The two ends of the cooling coil 73 penetrate the outer wall of the heat preservation box 72 and are fixedly connected. The cooling coil 73 on one side is arranged in a curved shape so as not to block the operation of the automobile parts.

[0032] Furthermore, one end of the cooling coil 73 is connected to the intake fan 74 , and the other end of the cooling coil 73 is connected to the exhaust fan 75 .

[0033] The heat dissipation component 7 starts the air intake fan 74 and the exhaust fan 75 at the same time, and continuously inputs the cold air in the cooling coil 73 into the cavity of the sound insulation protective shell 2 to form a cycle. The hot air discharged from the cycle is set in the heat preservation box 72, and is cooled by the refrigeration device 71 so that the temperature of the hot air can be reduced.

[0034] Working principle: First, the connecting block 5 and the mounting seat 3 can be installed in a fixed position by bolts, and at the same time, a shock-absorbing rubber pad 8 is placed between the mounting seat 3 and the vehicle base. Then, when the transmission body 1 generates noise during use, the noise generated during the operation of the transmission body 1 is absorbed and blocked by the sound-absorbing cotton layer 21, and the remaining part of the noise is completely isolated by the spacer layer composed of the inner protective plate 22, the outer protective plate 24 and the spacer block 23.

[0035] Then, when the transmission body 1 generates high temperature, the refrigeration device 71 is started first. The cold air outlet of the refrigeration device 71 is set upward and is located in the insulation box 72. Under the action of the exhaust fan 75, the heat inside the transmission body 1 is introduced into the interior of the cooling coil 73. Then, the air flow reaches the insulation box 72 and the temperature becomes lower. Under the action of the intake fan 74, it is guided back to the transmission body 1 to achieve internal cooling. The insulation box 72 can reduce the loss of cold air, so that the outer wall temperature of the transmission body 1 is rapidly reduced.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
