An exhaust structure of a vehicle control assembly

Abstract

The present invention discloses an exhaust structure for a vehicle control assembly, which includes a generator and a drive motor. A junction box is provided at the top left of the generator. Exhaust holes are respectively formed on the end cover on the right side of the generator and the end cover on the left side of the drive motor, so that the inner cavities of the generator and the drive motor are communicated. A flywheel housing is provided on the right side of the drive motor, and a breather valve is provided on the flywheel housing. This exhaust structure adopts the method of connecting the generator and the drive motor, and a breather valve for exhaust is designed on one side of the drive motor. When the generator and the drive motor generate heat during operation, the gas inside the two devices will expand, pushing up the breather valve, and the hot gas will be discharged from the breather valve. A partition for isolating gas is additionally provided at the corresponding position of the junction box of the generator to prevent hot gas from rising and forming condensed water due to temperature difference at the junction box, causing a short circuit in the wiring inside the junction box.

Description

Technical Field

[0001] The present invention belongs to the technical field of engines, and particularly relates to an exhaust structure of a vehicle control assembly. Background Art

[0002] At present, the vehicle control assembly adopted by new energy tractors includes a form in which a drive motor and a generator are combined with a gearbox. This method has certain stability advantages in transmission. After the drive motor and the generator work in series, power transmission can be achieved, and the power generation efficiency of the generator can be ensured. However, in the actual use process, there are problems of large heat generation in the generator and the engine, resulting in an increase in the temperature inside the drive motor and the generator. Although there is a cooling water channel for physical cooling, the air inside does not circulate. Therefore, the cooling effect of the cooling water channel is limited. Corresponding junction boxes are provided on both the drive motor and the generator. When the temperature difference between the inside and the outside of the drive motor and the generator is large, condensed water is likely to form near the junction box, and the contact between the condensed water and the controller is likely to cause a short circuit. Therefore, how to handle the high-temperature gas inside the drive motor and the generator is an urgent problem to be solved. Summary of the Invention

[0003] The purpose of the present invention is to provide an exhaust structure of a vehicle control assembly to solve the problems of large heat generation during operation and high temperature after the existing drive motor is connected in series with the generator; at the same time, hot air inside is likely to form condensed water in related areas, and short circuits will occur if it contacts the controller.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions:

[0005] An exhaust structure of a vehicle control assembly includes a generator and a drive motor. The drive motor is provided on the right side of the generator. A junction box is provided at the top right of the drive motor. Exhaust holes are respectively opened on the end cover on the right side of the generator and the end cover on the left side of the drive motor, so that the inner cavities of the generator and the drive motor are connected. A flywheel housing is provided on the left side of the generator, and a breather valve is provided on the flywheel housing;

[0006] The flywheel housing is hermetically connected to the generator, and the breather valve is opened at the top or side of the flywheel housing;

[0007] The end cover on the right side of the drive motor seals the junction box at the top right of the drive motor. A cavity is formed between the junction box and the end cover on the right side of the drive motor. The cavity is rectangular, and a partition is provided in the cavity.

[0008] Further, the exhaust holes on the end cover on the right side of the generator and the exhaust holes on the end cover on the left side of the drive motor are coaxially or staggeredly distributed.

[0009] Further, the exhaust holes provided on the end cover on the right side of the generator and the end cover on the left side of the drive motor are not limited to one place.

[0010] Further, the breather valve is a one-way valve or a waterproof breather valve.

[0011] The beneficial effects achieved by the present invention are as follows: This exhaust structure adopts a way of connecting the generator and the drive motor, and a breather valve for exhausting gas is designed on one side of the drive motor. When the generator and the drive motor generate heat during operation, the gas inside the two devices will expand, pushing up the breather valve, and the hot gas will be discharged from the breather valve, thereby reducing the hot gas inside the generator and the drive motor. When the temperature inside the generator and the drive motor decreases, the external gas will enter through the breather valve, making the pressure inside the generator and the drive motor tend to balance; a partition for isolating gas is added at the corresponding position of the junction box of the drive motor to prevent the hot gas from rising and forming condensed water due to temperature difference at the junction box, causing a short circuit in the lines inside the junction box.

[0015] The following will be specifically described with reference to specific embodiments.

[0016] The following will further describe the present invention in detail in conjunction with the specific embodiments. It should be emphasized that the following description is only

[0017] exemplary and not intended to limit the scope and application of the present invention.

[0018] As Figure 1 shown, an exhaust structure of a vehicle control assembly includes a generator 2 and a drive motor 7. The drive motor 7 is bolt-sealed and connected to the right side of the generator 2. A junction box 4 is provided at the top left of the drive motor 7. The end cover 6 on the right side of the drive motor 7 seals the junction box 4 at the top right of the drive motor 7. A cavity is formed between the junction box 4 and the end cover 6 on the right side of the drive motor 7. The cavity is rectangular. A partition 5 is provided inside the cavity to isolate the hot gas inside the drive motor 7 from entering the junction box 4, preventing condensed water from being formed in the junction box 4 due to temperature difference and causing a short circuit in the lines inside the junction box 4.

[0019] Exhaust holes 3 are respectively provided on the end cover on the right side of the generator 2 and the end cover on the left side of the drive motor 7, so that the inner cavities of the generator 2 and the drive motor 7 are connected. The exhaust hole 3 on the right end cover of the generator 2 and the exhaust hole 3 on the left end cover of the drive motor 7 are coaxially or staggeredly distributed. The staggered distribution can also connect the inner cavities of the generator 2 and the drive motor 7, while the coaxial distribution reduces the resistance during the air flow. The exhaust holes provided on the end cover on the right side of the generator 2 and the end cover on the left side of the drive motor 7 are not limited to one place, and can be increased or decreased according to requirements; the flywheel housing 8 is hermetically connected to the right side of the generator 2 by bolts. A breather valve 1 is provided on the flywheel housing 8. The breather valve 1 is provided on the top or side of the flywheel housing 8. Following the principle of hot air rising, it makes it easier for the hot air to be discharged from the breather valve 1. The breather valve 1 can be a one-way valve or a waterproof breather valve. Since the generator 2 needs to be waterproofed, it is more inclined to use a waterproof breather valve.
