Description

Technical Field

[0001] This utility model belongs to the field of vehicle powertrain, specifically, it relates to a dustproof structure for the generator-transformer interface. Background Technology

[0002] Due to structural limitations, the CVT transmission has four torque converter bolts, evenly distributed throughout the CVT. These bolts must be tightened after the engine and transmission bolts are tightened, and only after the engine and transmission bolts are assembled. A U-shaped groove is located at the bottom of the engine to allow for the installation of the torque converter bolts. This U-shaped groove needs to be protected and shielded to prevent dust and grit from entering the torque converter housing, affecting its operation, and potentially damaging internal components.

[0003] To address the aforementioned problems, patent application number 2014207425239 discloses a novel engine sealing dustproof baffle assembly, relating to the technical field of engine sealing dustproofing. It aims to overcome the problems of current sealing baffles between the starter and transmission being integrated with the cylinder block sealing baffle, resulting in an excessively large, thick, heavy baffle, wasted materials, high cost, and unstable sealing performance. Its baffle is a thin sheet with a thickness of 1mm or less, and has a through hole in the center. Multiple mounting holes are provided on the outer side of the hole, and the outer edge of the baffle has the same shape as the outer edge of the interface between the starter and transmission. A long strip of sponge pad is attached to the right edge of the baffle. However, this design does not solve the aforementioned problems.

[0004] Therefore, in order to improve or solve at least one of the above problems, a dustproof structure for the generator-transformer mating surface is provided, which can prevent dust and grit from entering the interior of the transmission housing through the gap between the generator and the transformer mating surface, improve the dustproof sealing effect, and avoid damage to the components.

To achieve the above objective, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides a dustproof structure for the engine-transmission joint surface, which includes a dustproof unit disposed between the engine and the transmission, located at the U-shaped groove at the bottom of the engine.

[0013] The technical effect of this utility model is as follows: The dustproof structure of the engine-transformer mating surface provided by this utility model includes a dustproof unit set between the engine and the transmission, located at the U-shaped groove at the bottom of the engine. It can prevent dust and gravel from entering the transmission housing through the gap between the engine and the transmission mating surface at the U-shaped groove, thereby improving the dustproof sealing effect and avoiding damage to the parts.

[0014] Therefore, the dustproof structure of the generator-transformer mating surface provided by this utility model can prevent dust and gravel from entering the inside of the transmission housing through the gap of the generator-transformer mating surface at the U-shaped groove, thereby improving the dustproof sealing effect and avoiding damage to the parts.

[0020] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0021] Figure 1 This is a schematic diagram of the dustproof structure of the generator-transformer bonding surface in an embodiment of this utility model; Figure 2 This is a schematic diagram of the dustproof structure at the generator-transformer interface in an embodiment of this utility model. Figure 3 This is a schematic diagram of the interface between the generator and the transformer in an embodiment of this utility model.

[0022] like Figure 1 , Figure 2 as well as Figure 3 As shown, the dustproof structure of the engine-transformer mating surface provided by this utility model includes a dustproof unit 10 disposed between the engine 1 and the transmission 2, located at the U-shaped groove 3 at the bottom of the engine 1. It can prevent dust and gravel from entering the transmission housing through the gap of the engine-transformer mating surface at the U-shaped groove 3, thereby improving the dustproof sealing effect and preventing damage to the parts.

[0023] like Figure 1 As shown, the dustproof unit 10 includes a dustproof baffle 11, which is installed on the engine 1. The dustproof baffle 11 is adapted to the U-shaped groove 3 at the bottom of the engine 1, and can cover the U-shaped groove 3 to prevent dust and gravel from entering the transmission housing through the gap between the engine and transmission mating surfaces at the U-shaped groove 3, thereby improving the dustproof sealing effect and preventing damage to parts.

[0024] like Figure 1 As shown, a limiting boss 12 is provided on one side of the dust baffle 11. The limiting boss 12 is locked between the engine 1 and the gearbox 2, located in the engine-transformer mating surface on one side of the U-shaped groove 3. It can prevent the dust baffle 11 from flipping or shifting during the installation process, which facilitates the installation of the dust baffle 11, improves the installation efficiency of the dust baffle 11, and reduces the installation cost of the dust baffle 11.

[0025] A limiting plate 13 is provided on one side of the dust baffle 11. The limiting plate 13 is located at the end of the dust baffle 11 away from the limiting boss 12. The limiting plate 13 abuts against the U-shaped groove 3 at the bottom of the engine. During the installation of the dust baffle 11, it further prevents the dust baffle 11 from flipping or shifting, facilitates the installation of the dust baffle 11, improves the installation efficiency of the dust baffle 11, and reduces the installation cost of the dust baffle 11.

[0026] The limiting plate 13 is connected to the mounting plate 14, which is connected to the engine 1. The mounting plate 14 is provided with mounting holes 15, which are used to connect the mounting plate 14 to the bolts on the engine 1, thereby installing the dust baffle 11 on the engine 1 for easy installation and removal. At the same time, during the tightening of the bolts, the limiting boss 12 and the limiting plate 13 can prevent the dust baffle 11 from flipping or shifting, thus avoiding the dust baffle 11 from tilting during installation and preventing interference with the hydraulic torque converter bolts, which could cause abnormal noise.

[0027] The dustproof unit 10 is integrally formed by punching. The thickness of the dustproof baffle 11 is 0.2mm smaller than the thickness of the gap between the generator and transformer mating surfaces, so that the limiting boss 12 on the dustproof baffle 11 can be engaged in the generator and transformer mating surface on one side of the U-shaped groove 3.
