Description

Technical Field

[0001] The present application relates to the field of engines, and in particular to an engine thrust plate. Background Art

[0002] As a kind of engine sliding bearing, the thrust plate mainly plays the role of axial support of the crankshaft in the engine. While ensuring the axial rotation of the crankshaft, it prevents the crankshaft from axial movement.

[0003] When installing the thrust plate, there is a front and back side. The front side has a groove and is installed outwards, and the back side is installed against the engine body. In the prior art, the installation position of the thrust plate is on the front and rear thrust surfaces of the cylinder main bearing seat. The surface with the cutout is the oil groove position, which is used to fill lubricating oil to prevent the crankshaft and the thrust plate from rubbing and heating up for lubrication. If the thrust plate oil groove is installed in the opposite direction, the thrust plate will be worn faster, causing the crankshaft to loosen left and right, the axial runout to increase, the piston to hit the cylinder, and the engine operation to be affected. In severe cases, it will cause serious damage to the engine components. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] See also Figure 1 to Figure 2 The present application first provides an embodiment of an engine thrust plate, which comprises:

[0032] The first thrust plate body 1 is provided with a first error-proofing component 11 and a second error-proofing component 12;

[0033] The second thrust plate body 2 is provided with a third error-proofing component 21 and a fourth error-proofing component 22;

[0034] The first thrust plate body 1 and the second thrust plate body 21 are respectively provided with a first anti-mistake hole 13 and a second anti-mistake hole 23, wherein the first anti-mistake hole 13 is provided on the left or right side of the first thrust plate body 1, and the second anti-mistake hole 23 is provided on the left or right side of the second thrust plate body 2, and the first anti-mistake hole 13 and the second anti-mistake hole 23 are used to mark the other side of the first thrust plate body 1 and the second thrust plate body 2 in contact with the machine body;

[0035] The first thrust plate body 1 and the second thrust plate body 2 are semicircular in design, the first error proofing component 11 and the second error proofing component 12 are respectively arranged on one side of both ends of the first thrust plate body 1, the first error proofing component 11 and the second error proofing component 12 have the same size and are half the width of the first thrust plate body 1;

[0036] The third error proofing component 21 and the fourth error proofing component 22 are respectively arranged on one side of both ends of the second thrust plate body 2. The third error proofing component 21 and the fourth error proofing component 22 have the same size and are half the width of the second thrust plate body 2.

[0037] The orientation of the second error prevention hole 23 is consistent with the orientations of the third error prevention component 21 and the fourth error prevention component platform. The first thrust plate body 1 has a first oil groove 14 on one side of the first error prevention hole 13, and the first oil groove 14 is used to store lubricating oil.

[0038] A second oil groove 24 is provided on one side of the second thrust plate body 2 where the second anti-misalignment hole 23 is provided. The second oil groove 24 is used to store lubricating oil.

[0039] The first error proofing component 11 and the second error proofing component 12 are designed as bosses, and the third error proofing component 21 and the fourth error proofing component 22 are designed as bosses.

[0040] The first thrust plate body 1 and the second thrust plate body 2 are embedded with the third error proofing component 21 through the first error proofing component 11, and the second error proofing component 12 and the fourth error proofing component 22 are embedded to form a complete circle.

[0041] Specifically, the error-proofing component is integrated with the thrust plate body. When the crankshaft is working, its state is not only rotating, but also there is axial movement force. Therefore, when designing the engine, the thrust plate is designed to prevent the crankshaft from driving the connecting rod due to axial movement, resulting in loosening of the gap between the crankshaft and the connecting rod during design.

[0042] In actual situations, thrust plates are mostly assembled on crankshafts or cylinder blocks, and the thrust plates provided in the embodiments of the present application are arranged on cylinder blocks. The thrust plate body needs to be assembled on the engine body first, and a cutout surface is arranged at the assembly location, and the cutout surface is used as an oil groove position, and the oil groove position is used to achieve a lubrication effect between the crankshaft and the thrust plate body.

[0043] The first thrust plate body and the second thrust plate body are respectively assembled on the cylinder body under actual use. In actual state, the frame of the cylinder body is divided into two parts, namely, an upper half and a lower half. The first thrust plate body and the second thrust plate body are respectively assembled on the upper half and the lower half of the cylinder body. After assembly, when the upper half and the lower half are combined, the first thrust plate body and the second thrust plate body are combined into a complete circle, so as to achieve the purpose of thrust when combined.

[0044] During assembly, if the thrust plate is installed in reverse, it will cause the anti-error components to conflict and fail to assemble, thus achieving the purpose of being idle.

[0045] In the embodiment of the present application, a material with an adsorption function is attached to the surface of the first thrust plate body 1 and the second thrust plate body 2 that contacts the machine body.

[0046] The thrust plate and the cylinder body cannot be directly connected by fixing, as fixing will cause the thrust plate to lose its function. Therefore, it needs to be fixed to the cylinder body by pasting. In the prior art, grease is generally used for pasting, but the grease pasting state is not stable enough, which will cause the thrust plate to slip from the cylinder body. Therefore, the embodiment of the present application avoids this problem by coating or coating the thrust plate body with a more adsorptive material, wherein the material with adsorptive effect is a magnetic material.

[0047] In the embodiment of the present application, the orientation of the first error-proofing hole 13 is consistent with the orientation of the first error-proofing component 11 and the second error-proofing component platform.

[0048] The anti-mistake hole serves as an obvious mark of the thrust plate and is set on the side that does not contact the cylinder body. During the alignment installation, the first anti-mistake hole and the second anti-mistake hole are not in the same direction. If they are in the same direction, it means that the thrust plate is installed in reverse.

[0049] It can be seen from the above technical scheme that the present application makes a misplaced notched boss structure facing right or left on both sides of the end face of the thrust plate. When the thrust plate is installed upside down, the bosses interfere with each other and cannot be installed, which plays an anti-error role. The thrust plate has only one anti-error hole, and is oriented in the same direction as the anti-error notch. On the back side of the thrust plate, magnetic material or other materials that require adsorption are coated. When installed on the machine body, the thrust plate relies on the magnetic material adsorbent on the back to prevent it from falling off the machine body. By providing the thrust plate body with an anti-error component and an anti-error hole as a fool-proof design, and using magnetic materials to make the thrust plate assembly more convenient, the failure rate of thrust plate assembly is reduced.

[0050] It should be noted that the above description of the disclosed embodiments enables professionals and technicians in the field to implement or use the present application. Various modifications to these embodiments will be apparent to professionals and technicians in the field, and the general principles defined herein can be implemented in other embodiments without departing from the scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but should conform to the widest scope consistent with the principles and novel features disclosed herein.
