Description

Technical Field

[0001] The utility model relates to the technical field of transmission shafts, in particular to an automobile transmission shaft with a telescopic function. Background Art

[0002] A car drive shaft with telescopic function is a drive shaft component designed to allow length changes. It is mainly used to compensate for axial displacement caused by suspension system activity, uneven road surface and vehicle load changes during vehicle driving. This type of drive shaft is usually used in front and rear wheel drive and four-wheel drive vehicles, especially in cars with front engine and rear wheel drive layout, because in this layout, the relative position between the transmission and the drive axle will change dynamically as the vehicle's motion state changes.

[0003] After searching, the patent number "CN219655118U" mentioned in the text that "the utility model relates to the technical field of transmission shafts, and in particular to an automobile transmission shaft. Its technical solution includes a universal joint, a shaft sleeve and a connecting shaft, the inner wall of the shaft sleeve is provided with a first spline groove, a spline shaft is movably inserted inside the shaft sleeve, the spline shaft is located at one end outside the shaft sleeve and is fixedly connected to the connecting shaft, an annular groove is provided on the side of the inner wall of the shaft sleeve close to the spline shaft, and a rubber sealing ring and an oil-absorbing sponge ring are installed inside the annular groove. The utility model can reduce the wear between the connecting shaft and the shaft sleeve and extend the service life of the transmission shaft", During use, by arranging the shaft sleeve, the first spline groove, the spline shaft, the connecting shaft, the annular groove, the rubber sealing ring and the oil-absorbing sponge ring, the effect of reducing the wear between the connecting shaft and the shaft sleeve and extending the service life of the transmission shaft is achieved. However, long-term telescopic movement will accelerate the use of lubricant. When the lubrication is poor, it will cause direct contact between metal parts. The lack of protection of the lubricating film will cause abnormal wear on the metal surface quickly, and even cause scratches, biting or sintering. This not only aggravates the physical loss of parts, but is also accompanied by harsh noise, high temperature and other problems, seriously affecting the normal operation and service life of the equipment.

[0004] Therefore, we provide an automobile transmission shaft with telescopic function to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a vehicle transmission shaft with a telescopic function, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a transmission shaft of an automobile with a telescopic function, comprising a sealing disc and a lubricating mechanism, a shaft sleeve is installed on one side of the sealing disc, and a lubricating mechanism is arranged on the outer side of the shaft sleeve;

[0007] The lubrication mechanism includes a connecting component, a storage component, a control component, an oil injection component and a sealing component. The connecting component is arranged on the outer side of the sleeve, the storage component is arranged on one side of the connecting component, the control component is installed on the surface of the storage component, the oil injection component is installed on the inner side of the connecting component, and the sealing component is installed inside the sealing disk.

[0008] Preferably, the connecting assembly comprises a connecting piece and a hose, the connecting piece is installed on the outer side of the sleeve, and the hose is installed on the surface of the connecting piece.

[0009] Preferably, the storage assembly includes a lubrication pump and an oil storage tank, the lubrication pump is installed on the other side of the hose, and the oil storage tank is installed at the bottom end of the lubrication pump.

[0010] Preferably, the control component includes a PLC controller and a human-machine interactive touch screen, the PLC controller is installed on the surface of the oil storage tank, and the human-machine interactive touch screen is installed on the surface of the PLC controller.

[0011] Preferably, the oil injection assembly comprises a distributor and a nozzle, the distributor is installed on the inner side of the connecting piece, and the nozzle is installed on the outer side of the distributor.

[0012] Preferably, the sealing assembly comprises a throttling channel and a gap, a throttling channel is provided on the inner side of the sealing disk, and a gap is provided inside the sealing disk.

[0013] Preferably, a telescopic assembly is sleeved inside the shaft sleeve, and the telescopic assembly includes a telescopic tube and a spline. The shaft sleeve is sleeved inside the shaft sleeve, and the inner side of the telescopic tube is slidably connected with a spline.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. Through the setting of the lubrication mechanism, before work, the user can set the execution time interval and number of lubrication tasks through the PLC controller. Once the cumulative running time of the transmission shaft reaches the preset time, the PLC controller will accurately trigger the lubrication pump action, and the lubrication pump will then extract sufficient lubricant from the oil storage tank. After the lubricant is extracted through the built-in efficient suction system, the lubricant is transmitted to the connector through a hose. After that, the lubricant flows into the distributor. The distributor strictly follows the pre-programmed logical sequence and dosage standards to accurately and evenly spray the lubricant through a series of nozzles onto the telescopic tube and spline contact surface of the transmission shaft. In this way, a tough and continuous lubricating film can be formed on these parts, effectively reducing the direct contact between metal parts, greatly reducing the energy loss caused by friction and wear, and curbing the generation of abnormal noise. It significantly improves the working efficiency and service life of the transmission shaft and ensures the long-term stable operation of the equipment.

[0016] 2. Through the setting of the sealing component, when the high-pressure fluid tries to penetrate the sealing disc structure, it must go through a winding and extremely small cross-section throttling channel. In this process, the fluid is forced to pass through a series of dense and narrow gaps. The huge fluid resistance generated causes the fluid to significantly reduce its speed when flowing. As the flow rate drops sharply, the original kinetic energy of the fluid is largely converted into heat energy, thereby effectively attenuating its penetration ability. This greatly hinders pollutants such as dust and moisture from entering the interior along with the fluid, thereby preventing these impurities from contaminating the lubricating oil and ensuring the cleanliness and lubrication efficiency of the equipment.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] See also Figure 1-4 As shown, the utility model provides a technical solution: a transmission shaft of an automobile with a telescopic function, comprising a sealing disc 1 and a lubricating mechanism 3, a shaft sleeve 2 is installed on one side of the sealing disc 1, and a lubricating mechanism 3 is arranged on the outer side of the shaft sleeve 2;

[0025] The lubrication mechanism 3 includes a connecting component 31, a storage component 32, a control component 33, an oil injection component 34 and a sealing component 35. The connecting component 31 is arranged on the outer side of the sleeve 2, the storage component 32 is arranged on one side of the connecting component 31, the control component 33 is installed on the surface of the storage component 32, the oil injection component 34 is installed on the inner side of the connecting component 31, and the sealing component 35 is installed inside the sealing disk 1.

[0026] Furthermore, the connecting assembly 31 includes a connecting piece 311 and a hose 312. The connecting piece 311 is installed on the outer side of the sleeve 2, and the hose 312 is installed on the surface of the connecting piece 311 to connect the lubrication pump 321 and the distributor 341 to ensure accurate delivery of the lubricant.

[0027] Furthermore, the storage assembly 32 includes a lubrication pump 321 and an oil storage tank 322 . The lubrication pump 321 is installed on the other side of the hose 312 , and the oil storage tank 322 is installed at the bottom end of the lubrication pump 321 . The lubrication pump 321 is used to extract lubricant and pressurize it to deliver it to the connector 311 .

[0028] Furthermore, the control component 33 includes a PLC controller 331 and a human-computer interaction touch screen 332. The PLC controller 331 is installed on the surface of the oil tank 322, and the human-computer interaction touch screen 332 is installed on the surface of the PLC controller 331. The user can program the PLC controller 331 through the human-computer interaction touch screen 332.

[0029] Furthermore, the oil spray assembly 34 includes a distributor 341 and a nozzle 342 . The distributor 341 is installed on the inner side of the connecting piece 311 , and the nozzle 342 is installed on the outer side of the distributor 341 . The distributor 341 can release a fixed amount of lubricant in sequence according to the time intervals preset by the PLC controller 331 .

[0030] Furthermore, the sealing assembly 35 includes a throttling channel 351 and a gap 352. The throttling channel 351 is opened on the inner side of the sealing disk 1, and the gap 352 is opened inside the sealing disk 1. When the high-pressure fluid attempts to penetrate the sealing disk 1 structure, it must pass through a winding throttling channel 351 with a very small cross-section. In this process, the fluid is forced to pass through a series of dense and narrow gaps 352. The huge fluid resistance generated causes the fluid to significantly reduce its speed when flowing.

[0031] Embodiment 2

[0032] See also Figure 2As shown, in contrast to Example 1, as another implementation of the utility model, the interior of the shaft sleeve 2 is sleeved with a telescopic assembly 4, and the telescopic assembly 4 includes a telescopic tube 41 and a spline 42. The interior of the shaft sleeve 2 is sleeved with the telescopic tube 41, and the inner side of the telescopic tube 41 is slidably connected with the spline 42. The spline 42 component is nested in the telescopic tube 41, and the two constitute a relatively slidable connection relationship. When the vehicle is driving, if the axial distance changes due to factors such as the activity of the suspension system and load changes, the spline 42 can flexibly slide and telescope inside the telescopic tube 41, thereby synchronously adjusting the total length of the drive shaft to ensure the stability and continuity of the power transmission.

[0033] Working principle: First, move the automobile transmission shaft with telescopic function to the working position. When in use, the first step is that when the vehicle is driving, when the axial distance changes due to factors such as suspension system activity and load changes, the spline 42 can flexibly slide and telescope inside the telescopic tube 41, thereby synchronously adjusting the total length of the transmission shaft to ensure the stability and continuity of the power transmission. The second step is that before work, the user can set the execution time interval and number of lubrication tasks through the PLC controller 331. Once the cumulative running time of the transmission shaft reaches the preset time, the PLC controller 331 will accurately trigger the lubrication pump 321 to operate. The lubrication pump 321 then draws sufficient lubricant from the oil storage tank 322. After the lubricant is drawn out through the built-in efficient suction system, the lubricant is transmitted to the connector 311 through the hose 312. After that, the lubricant flows into the distributor 341 and is distributed. The distributor 341 strictly follows the pre-programmed logical sequence and dosage standards to accurately and evenly spray the lubricant onto the contact surfaces of the telescopic tube 41 and the spline 42 of the transmission shaft through the nozzle 342, so that a tough and continuous lubricating film can be formed on these parts, effectively reducing the direct contact between metal parts and greatly reducing the energy loss caused by friction and wear. In the third step, when the high-pressure fluid attempts to penetrate the sealing disk 1 structure, it must go through a tortuous throttling channel 351 with a very small cross-section. In this process, the fluid is forced to pass through a series of dense and narrow gaps 352. The huge fluid resistance generated causes the fluid to significantly reduce its speed when flowing. As the flow rate drops sharply, the original kinetic energy of the fluid is largely converted into heat energy, thereby effectively attenuating its penetration ability, thus completing the use process of the automobile transmission shaft with telescopic function.
