[0028] As Figures 1-5The utility model provides a kind of automobile oil seal cover with multiple sealing structure, including the oil seal cover body 1 being installed on shaft 3, the oil seal cover body 1 includes front section sealing structure 114, rear section sealing structure 115 and sealing interval adjusting structure 2, the front section sealing structure 114 and rear section sealing structure 115 between being equipped with the mounting portion 101 for installing sealing interval adjusting structure 2, the sealing interval adjusting structure 2 is connected respectively front section sealing structure 114 with rear section sealing structure 115.
[0029] In the working process of the embodiment, the sealing effect between the front section sealing structure 114 and the rear section sealing structure 115 may be affected due to temperature changes, wear or different operating conditions. A dust screen is provided on the mounting portion 101. The sealing interval adjusting structure 2 allows the user to dynamically adjust the sealing interval according to the actual situation, ensuring the best sealing state.
[0030] The front section sealing structure 114 includes a movable ring one 110, a first oil seal component 102 and a second oil seal component 103. The movable ring one 110 is connected with the first oil seal component 102. The first oil seal component 102 and the second oil seal component 103 are symmetrically arranged. The rear section sealing structure 115 includes a movable ring two 111 and a sealing element 104. A compression spring 113 is arranged between the movable ring one 110 and the movable ring two 111.
[0031] The front section sealing structure 114 and the rear section sealing structure 115 in the embodiment achieve sealing effect through oil seal components. The movable ring one 110, the first oil seal component 102 and the second oil seal component 103 in the front section sealing structure 114 interact to form a good sealing interface. The rear section sealing structure 115 is composed of the movable ring two 111 and the sealing element 104, ensuring the uniformity and stability of the sealing effect.
[0032] The sealing interval adjusting structure 2 includes a first adjusting sleeve ring 201, a second adjusting sleeve ring 202 and a mounting sleeve 203. The mounting sleeve 203 is connected with the first adjusting sleeve ring 201 and the second adjusting sleeve ring 202. The first adjusting sleeve ring 201 and the second adjusting sleeve ring 202 are movably arranged on the mounting sleeve 203. A plurality of tension springs 206 are arranged at the connection between the first adjusting sleeve ring 201, the second adjusting sleeve ring 202 and the mounting seat. The first adjusting sleeve ring 201 is connected with the movable ring one 110. The second adjusting sleeve ring 202 is connected with the movable ring two 111.
[0033] The sealing distance adjusting structure 2 in this embodiment comprises a first adjusting ring 201, a second adjusting ring 202 and a mounting sleeve 203. By adjusting the relative movement of the movable adjusting rings, the distance between the front sealing structure 114 and the rear sealing structure 115 can be effectively adjusted, so as to optimize the sealing performance. The tensile spring 206 provides additional force at the connection of the adjusting ring, helping to maintain the tightness of the sealing ring 112 and ensuring that the sealing effect will not be weakened due to the change of the gap. The first rubber sealing ring 108 and the second rubber sealing ring 109 can be compressed towards the center of the guide seat by the compression spring 113, thereby improving the sealing effect, and the dustproof and waterproof sealing ring 112 is provided to prevent the intrusion of external substances and improve the service life. At the same time, the leakage monitoring sensor 105 is arranged to monitor the possible leakage in real time, thereby enhancing the safety and reliability of the system.
[0034] Further, the first oil seal component 102 comprises a first sleeve and a sealing lip one 106 connected to the first sleeve, and the second oil seal component 103 comprises a second sleeve and a sealing lip two 107 connected to the second sleeve, and the first sleeve is connected to the second sleeve.
[0035] The sealing lip one 106 is in contact with the surface of the rotating shaft 3 to form a sealing interface. The sealing lip two 107 is also in contact with the shaft 3 to provide a second sealing interface. The connection of the first sleeve and the second sleeve makes the two oil seal components form an integral sealing system. Through the joint action of the two sealing lips, a multiple sealing effect is formed. This structure can effectively disperse the internal and external pressure and allow compensation for displacement caused by temperature changes, pressure changes and movement of the shaft 3 during work, thereby increasing the reliability of the seal.
[0036] Specifically, when the shaft 3 rotates, the friction between the sealing lip and the surface of the shaft 3 will generate a certain mechanical resistance, keeping the lip tightly attached to the surface of the shaft 3 and preventing oil leakage. Through the elasticity and compression of the sealing lip, the oil seal component can effectively withstand the lateral movement of the shaft 3 and ensure that the sealing state is continuously maintained under working conditions.
[0037] Further, the leakage monitoring sensor 105 is arranged between the first sleeve and the second sleeve. The leakage monitoring sensor 105 arranged between the first sleeve and the second sleeve can monitor the pressure change and the leakage of the oil seal in real time. The sensor can detect early signs of sealing failure, such as oil and gas leakage or abnormal temperature of the assembly, which is usually fed back to the central control system or the instrument panel through an electrical signal, prompting maintenance personnel to check.
[0038] Further, a guide seat is arranged between the first movable ring 110 and the second movable ring 111, and the guide seat is connected with the mounting sleeve 203. The guide seat is provided with the first rubber sealing ring 108 and the second rubber sealing ring 109, and the first rubber sealing ring 108 and the second rubber sealing ring 109 are movably arranged on the two sides of the guide seat respectively. The first rubber sealing ring 108 and the second rubber sealing ring 109 are connected with the compression spring 113 respectively.
[0039] The guide seat arranged between the first movable ring 110 and the second movable ring 111 provides structural support and ensures the stability of the sealing ring when the movable ring moves. The first rubber sealing ring 108 and the second rubber sealing ring 109 are respectively arranged on the two sides of the guide seat and are connected with the first movable ring 110 and the second movable ring 111.
[0040] The guide seat is provided with cavities on the two sides for the first rubber sealing ring 108 and the second rubber sealing ring 109. The first rubber sealing ring 108 and the second rubber sealing ring 109 can be compressed to the center of the guide seat by the compression spring 113 on the spacing adjustment structure, and are used in cooperation with the tension spring 206. The first rubber sealing ring 108 and the second rubber sealing ring 109 can adjust and stably maintain the sealing spacing therebetween. When the first movable ring 110 and the second movable ring 111 move relatively, the compression or extension of the spring provides adaptive ability, so that the sealing ring can adapt to the change of the spacing at any time.
[0041] Further, the first rubber sealing ring 108 is connected with the first movable ring 110, and the second rubber sealing ring 109 is connected with the second movable ring 111. The first rubber sealing ring 108 and the second rubber sealing ring 109 are both provided with a dustproof and waterproof sealing ring 112.
[0042] The sealing spacing between the first rubber sealing ring 108 and the second rubber sealing ring 109 can be adjusted according to the needs of the spacing condition structure. The elasticity of the spring ensures the stability of the sealing spacing, which can maintain effective sealing whether in normal operation or under the action of external factors such as vibration.
[0043] Each sealing ring is equipped with a dustproof and waterproof sealing ring 112, which further improves the sealing effect. Such protective design can effectively prevent the invasion of dirt and the penetration of water, and protect the integrity of the internal mechanical parts.
[0044] Further, the first adjusting sleeve 201 and the second adjusting sleeve 202 are coaxially connected with the mounting sleeve 203 along the axis 3, and the tension spring 206 is distributed in a circumferential array along the axis 3 of the mounting sleeve 203.
[0045] The first adjusting sleeve 201 and the second adjusting sleeve 202 are coaxially connected and installed in the mounting sleeve 203, forming the core part of the adjusting mechanism. The first adjusting sleeve 201 and the second adjusting sleeve 202 are movable to both sides of the mounting sleeve 203 through the tension of the tension spring 206.
[0046] Further, the first adjusting sleeve 201 and the second adjusting sleeve 202 are provided with a plurality of adjusting grooves 205, and the mounting sleeve 203 is further provided with a limiting column 204 corresponding to the adjusting grooves 205. The adjusting sleeve can be accurately positioned when moving under the control of the limiting column 204. The limiting column 204 is correspondingly clamped in the adjusting groove 205 through the movement of the first adjusting sleeve 201 and the second adjusting sleeve 202. The relative tension provided by the tension spring 206 can effectively adjust the distance between the two sides.
