Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and in particular to a timing cover, engine, and vehicle. Background Technology

[0002] With increasingly stringent environmental regulations, fuel efficiency and emissions requirements for vehicles are also rising, leading to a trend towards lighter automotive component designs, including timing covers. Timing cover wall thickness is typically around 4mm to reduce weight. Furthermore, timing covers integrate multiple functions, such as mounting bosses for vehicle suspension, OCV (Oil Control Valve) mounting bosses, and dipstick tubes, thus achieving the goal of weight reduction.

[0003] However, the more functions integrated into the timing cover, the higher the requirements for its strength and rigidity. Timing covers in related technologies often have low structural strength and poor rigidity, making them prone to deformation during long-term vehicle use. This can lead to engine oil leaks and, in severe cases, damage the engine, causing even greater economic losses. Summary of the Invention

[0031] The accompanying drawings have illustrated specific embodiments of this disclosure, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0032] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0033] With increasingly stringent environmental protection requirements, vehicle fuel consumption and emission standards are becoming more stringent, leading to a trend towards lighter automotive component designs, including engine timing covers. Timing cover wall thickness is typically around 4mm to reduce weight. Furthermore, timing covers integrate multiple functions, such as mounting bosses for vehicle suspension, OCV (Oil Control Valve) mounting bosses, and dipstick tubes, thus achieving the goal of weight reduction.

[0034] However, the more functions integrated into the timing cover, the higher the requirements for its strength and rigidity. The timing covers in related technologies have low structural strength and poor rigidity, making them prone to deformation during long-term vehicle use. This can lead to engine oil leaks and, in severe cases, damage the engine, causing significant economic losses.

[0035] In view of this, according to one aspect of the present disclosure, a timing cover is provided that has higher strength. Figure 1 A schematic diagram of a timing cover provided in an embodiment of this disclosure; Figure 2 This is a schematic diagram of a timing cover provided in an embodiment of this disclosure. Figure 1 and 2 As shown, the timing cover provided in this embodiment includes a cover body 1 and a flange 2. The flange 2 is connected to at least a portion of the edge of the cover body 1. The cover body 1 has opposing inner and outer sides. The outer side is provided with a curved recessed structure 101, and the inner side is provided with reinforcing ribs 102. The flange 2 has a textured structure 201 on the side near the inner side. The flange 2 is configured to be connected to the engine block.

[0036] In the timing cover provided in this embodiment, the outer side of the cover body 1 is provided with a curved recessed structure 101, and the inner side of the timing cover 1 is provided with reinforcing ribs. Compared with a flat timing cover, the timing cover provided in this embodiment has higher modal strength and greater strength. Furthermore, the flange 2 of the timing cover has a textured structure 201 on the side near the inner side. The textured structure 201 can accommodate sealing colloid, making the connection between the timing cover and the engine block tighter, preventing engine oil from leaking through the gaps in the timing cover, and simultaneously reducing engine noise transmission, thus playing a role in sound insulation and noise reduction. Most of the noise generated by the high-speed operation of the timing valve train during engine operation radiates from the front end of the timing cover. The structure of the timing cover provided in this embodiment can suppress the transmission of vibration noise from the timing valve train system.

[0037] To make the technical solutions and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0038] like Figure 1 As shown, the timing cover provided in this disclosure includes a cover body 1 and a flange 2, with the flange 2 connected to at least a portion of the edge of the cover body 1. Exemplarily, the flange 2 is connected to opposite side edges of the cover body 1, and the flange 2 is used to connect the timing cover to the engine block. The cover body 1 has opposing inner and outer sides, where the inner side refers to the side closer to the engine block, and the outer side refers to the side farther from the engine block. The outer side of the cover body 1 is provided with a curved recessed structure 101, and the inner side is provided with a reinforcing rib 102. The recessed structure 101 and the reinforcing rib 102 are used to improve the stress distribution of the timing cover. Compared to a flat-plate timing cover, the timing cover provided in this disclosure embodiment has higher modal strength and greater strength. The flange 2 has a textured structure 201 on its inner side. After the flange 2 is connected to the engine block, an uneven gap can be formed between the textured structure 201 on the inner side of the flange 2 and the engine block. This textured structure 201 can accommodate sealant or a gasket, thereby completely sealing the gap between the timing cover and the engine block and preventing oil leakage from the engine. Furthermore, the sealing structure of the flange 2 can reduce engine noise transmission, thus providing sound insulation and noise reduction.

[0039] For example, the textured structure 201 may be a plurality of grooves arranged at equal intervals along a first direction and a plurality of grooves arranged at equal intervals along a second direction, wherein the first direction and the second direction intersect. Alternatively, the cross-sectional shape of the textured structure 201 may be wavy, thereby forming a regular gap between the flange 2 and the engine body.

[0040] In some embodiments of this disclosure, such as Figure 1 As shown, a protrusion 107 is provided on the outer side of the timing cover body 1. The protrusion 107 has a threaded hole for connecting the engine mount, so that the engine can be connected to the frame through the mount. The structure of the protrusion 107 can improve the stress distribution of the timing cover and help increase the strength of the timing cover.

[0041] In some embodiments of this disclosure, such as Figure 2 As shown, the inner surface of the cover body 1 is provided with multiple connecting portions 103, and reinforcing ribs 102 are radially distributed around the connecting portions 103. For example, the inner surface of the cover body 1 is provided with three connecting portions 103, which are not arranged on the same straight line. Each connecting portion 103 is surrounded by multiple radially distributed reinforcing ribs, which extend from the connecting portion 103 to the flange 2 at the edge. Two relatively close connecting portions 103 are connected by two reinforcing ribs 102. The connecting portion 103 has a cylindrical structure, and its length direction is approximately perpendicular to the plane of the cover body 1. The connecting portion 103 may be provided with threaded holes. The connecting portion 103 is used to connect the timing cover 1 to the engine block.

[0042] In some embodiments of this disclosure, such as Figure 2 As shown, flange 2 is provided with multiple connection holes 205, and flange 2 is connected to the engine block through multiple connection holes 205 and bolts. The engine block may be provided with multiple threaded holes, each threaded hole can be aligned with a connection hole 205, so that flange 2 can be connected to the engine block by bolts.

[0043] Optionally, see Figure 2 The flange 2 is also provided with multiple disassembly holes 206, which are through holes, each with an internal thread. After the timing cover is connected to the engine block, the position on the engine block opposite the disassembly holes 206 is a closed structure. When it is necessary to remove the timing cover, after removing the bolts in the connecting hole 205, it is difficult to remove the timing cover directly due to the adhesive bond between the flange 2 and the engine block. Therefore, a bolt can be screwed into the disassembly hole 206. The bolt can apply a force away from the engine through the internal thread in the disassembly hole 206, thereby lifting the timing cover and making it easier to separate the timing cover from the engine block.

[0044] Figure 3 This is a schematic diagram of a timing cover provided according to an embodiment of this disclosure. In some embodiments of this disclosure, such as... Figure 3As shown, the timing cover also includes a scale 3. A flange 2 extends along the length of the cover body 1 and is located on opposite sides of the cover body 1. One end of the cover body 1 along its length has a gantry portion 104 protruding from the end of the flange 2. A first mounting hole 106 is provided at the end of the gantry portion 104, and the scale 3 is located in the first mounting hole 106, which extends to the inner side of the cover body 1. The scale 3 can communicate with the engine interior, thereby detecting the engine oil level, facilitating the detection of engine operating conditions and identifying faults.

[0045] In some embodiments of this disclosure, see Figure 2 The end of the cover body 1 furthest from the gantry portion 104 is provided with a crankshaft mounting hole 109. The inner surface of the cover body 1 is provided with radially arranged reinforcing ribs 102 centered on the crankshaft mounting hole 109. Furthermore, reinforcing ribs 102 are provided on both the upper and lower sides of the inner surface of the cover body 1 at the crankshaft mounting hole 109 to increase the strength of the timing cover at the crankshaft mounting hole 109. The width of the cover body 1 gradually decreases in the direction from the gantry portion 104 to the crankshaft mounting hole 109.

[0046] like Figure 3 As shown, after installation, one end of the scale 3 is inserted into the first mounting hole 106 and is detachably connected to the scale tube 4 on the inner side of the cover body 1.

[0047] Figure 4 A partial cross-sectional view of a timing cover provided for an embodiment of this disclosure. In some embodiments of this disclosure, such as... Figure 3 and 4 As shown, one end of the scale 3, located within the first mounting hole 106, is configured to connect to the scale tube 4. A chamfered structure 1061 is provided at the end of the first mounting hole 106 near the scale tube 4. When the scale 3 is installed in the first mounting hole 106, one end of the scale 3 partially protrudes from the first mounting hole 106 at the chamfered structure 1061. Therefore, when it is necessary to remove the scale 3, it can be directly pushed outward from the inner side of the cover body 1, solving the problem of difficulty in removing the scale 3. For example, the chamfered structure 1061 has an inclination angle of 45 degrees.

[0048] Figure 5 for Figure 1 A partial schematic diagram of region a of the timing cover is shown. In some facts of this disclosure, such as... Figure 1 , 2 As shown in Figure 5, the timing cover also includes a hydraulic control valve 5. A second mounting hole 105 is provided on the cover body 1. The second mounting hole 105 connects the inner side and the outer side of the cover body 1. The hydraulic control valve 5 is located in the second mounting hole 105.

[0049] Specifically, see Figure 1-2 The second mounting hole 105 is provided at the end of the cover body 1 and in region a. Two second mounting holes 105 are provided at the end of the cover body 1. An arc-shaped recess 108 is provided between the two second mounting holes 105. The first mounting hole 106 is located between the two second mounting holes 105. The arc-shaped recess 108 is used to increase the strength of the cover body 1 and prevent the second mounting holes 105 from reducing the strength of the timing cover too much.

[0050] Among the facts disclosed herein, such as Figure 5 As shown, the cover body 1 has a first boss 1051 at the second mounting hole 105 in region a. The surface of the first boss 1051 has a first included angle structure 1052. The outer wall of the hydraulic control valve 5 has a second included angle structure 501, which engages with the first included angle structure 1052. The hydraulic control valve 5 is connected to the oil pump wiring harness 6. When the hydraulic control valve 5 is installed in the second mounting hole 105, the second included angle structure 501 abuts against the first included angle structure 1052, thereby preventing the hydraulic control valve 5 from rotating relative to the cover body 1 and avoiding loosening of the connection between the hydraulic control valve 5 and the cover body 1 due to vibration.

[0051] The first included angle structure 1052 and the second included angle structure 501 have the same angle. For example, the angles of the first included angle structure 1052 and the second included angle structure 501 are both 90 degrees.

[0052] Figure 6 This is a partial schematic diagram of a timing cover provided in an embodiment of this disclosure. In some embodiments of this disclosure, such as... Figure 6 As shown, two second mounting holes 105 are located at the gantry portion 104, and a hydraulic control valve 5 is installed in each mounting hole 105. A second boss 1053 and a third boss 1054 are provided on the outer side of the cover body 1. Two third mounting holes 1055 are provided on the second boss 1053 and the third boss 1054. The line connecting the centers of the two third mounting holes 1055 on the second boss 1053 passes through the center of the second mounting hole 105, and the line connecting the centers of the two third mounting holes 1055 on the third boss 1054 also passes through the center of the second mounting hole 105. The hydraulic control valve 5 is fixedly connected to the cover body 1 through the third mounting holes 1055.

[0053] In some embodiments of this disclosure, the average wall thickness of the cover body 1 is 2.5 mm to 3.5 mm. Preferably, the average wall thickness of the cover body 1 is 3 mm. The timing cover provided in the embodiments of this disclosure, due to the presence of a protrusion 107, a recessed structure 101, and an arc-shaped recess 108 on the cover body 1, significantly improves the modal and stress distribution of the timing cover, disrupts the vibration frequency at various positions of the timing cover, prevents resonance, and also improves the strength of the timing cover, achieving a thinner cover body 1, thereby further reducing the weight of the timing cover and contributing to the realization of lightweight vehicles.

[0054] It should be noted that the cover body 1 and the flange 2 involved in the embodiments of this disclosure are integrally formed, for example by casting, and the protrusion 107, the first boss 1051, the second boss 1053 and the first included angle structure 1053 are formed by mold during the forming process.

[0055] On the other hand, this disclosure also provides an engine, which includes a body 100, a seal 7, and any of the timing covers described above, wherein the seal 7 is located between the body 100 and the flange 2.

[0056] In the engine provided in this embodiment, the outer side of the timing cover body 1 is provided with a curved recessed structure 101, and the inner side of the timing cover 1 is provided with reinforcing ribs. Compared with a flat timing cover, the timing cover provided in this embodiment has higher modal strength and greater strength. Furthermore, the flange 2 of the timing cover has a textured structure 201 on the side near the inner side. The textured structure 201 can accommodate a gasket, allowing the gasket to fill the gap between the flange 2 and the engine block, thus making the connection between the timing cover and the engine block tighter, preventing oil leakage from the engine, and reducing engine noise transmission, thus playing a role in sound insulation and noise reduction. Most of the noise generated by the high-speed operation of the timing valve train during engine operation is radiated from the front end of the timing cover. The structure of the timing cover provided in this embodiment can suppress the transmission of vibration noise from the timing valve train system. The design of the timing cover's OCV valve results in a gantry section 104 at the top of the timing cover. This means that the sealing surface of the timing cover at the gantry section 104 is not flat, ensuring good sealing performance and preventing oil leakage during engine operation.

[0057] Figure 7 A partial cross-sectional view of an engine provided for an embodiment of this disclosure. In some embodiments of this disclosure, such as... Figure 7As shown, the timing cover flange 2 is opposite to the engine block 100, and the flange 2 is bolted to the engine block 100. The cross-sectional shape of the mesh structure 201 is sawtooth-shaped, and the end face of the engine block 100 opposite to the flange 2 is also provided with a sawtooth structure. A sealing gasket 7 is provided between the engine block 100 and the flange 2. The sealing gasket 7 can undergo elastic deformation under the compression of the flange 2 and the engine block 100, thereby sealing the gap between the engine block 100 and the flange 2. Moreover, the sawtooth-shaped mesh structure 201 can increase the friction between the engine block 100, the flange 2 and the sealing gasket 7, preventing the seal between the engine block 100 and the flange 2 from failing due to engine vibration.

[0058] Additionally, this disclosure also provides a vehicle that includes the timing cover described in any of the above embodiments.

[0059] In the vehicle provided in this embodiment, the outer side of the timing cover body 1 is provided with a curved recessed structure 101, and the inner side of the timing cover 1 is provided with reinforcing ribs. Compared with a flat timing cover, the timing cover provided in this embodiment has higher modal strength and greater strength. Furthermore, the flange 2 of the timing cover has a textured structure 201 on the side near the inner side. The textured structure 201 can accommodate a sealing gasket, allowing the gasket to fill the gap between the flange 2 and the engine block 100, thereby making the connection between the timing cover and the engine block 100 tighter, preventing oil leakage from the engine, and reducing engine noise transmission, thus playing a role in sound insulation and noise reduction. Most of the noise generated by the high-speed operation of the timing valve train during engine operation radiates from the front end of the timing cover. The structure of the timing cover provided in this embodiment can suppress the transmission of vibration noise from the timing valve train system. The design of the timing cover's OCV valve results in a gantry section 104 at the top of the timing cover. This means that the sealing surface of the timing cover at the gantry section 104 is not flat, ensuring good sealing performance and preventing oil leakage during engine operation.
