Description

Technical Field

[0001] This invention relates to the field of traction seat mounting plates, specifically a traction seat mounting plate that can rotate horizontally. Background Technology

[0002] Road transport is the core mode of transporting bulk commodities and large equipment. As a key component connecting the tractor and trailer, the structural rationality of the tow seat mounting plate directly affects the overall vehicle driving safety. Currently, the mainstream tow seat mounting plates are flat or corrugated, both using an integrated fixed structure and rigidly connected to the tractor's main beam. They cannot achieve self-adaptive horizontal rotation and can only meet the basic requirements of simple road conditions.

[0003] The following problems in the existing technology have not been adequately addressed: 1. Poor stability under complex working conditions and prominent safety hazards. When the vehicle travels on a road with curves and slopes, the axle of the semi-trailer and the tractor forms an angle. The swing angle axis of the fixed mounting plate cannot be adaptively adjusted, resulting in a serious deviation of the vertical load of the trailer. This not only increases the difficulty of driving and operation, but may also cause one side of the tractor's rear wheel to lift off the ground, power interruption, or even major safety accidents such as vehicle rollover. 2. Inadequate lubrication system design and severe component wear. The existing mounting plate relies on manual periodic grease application, which lacks a precise grease guiding and even grease distribution structure, making it prone to lubrication dead zones. Moreover, under high-frequency deflection or heavy-load conditions, the grease is quickly lost, resulting in a long grease replenishment cycle, which leads to accelerated wear on the mating surfaces, shortens the service life of components, and increases maintenance costs and downtime.

[0014] The output end of the arc-shaped piston cylinder is equipped with a one-way valve;

[0015] An arc-shaped limiting groove is provided at the bottom left side of the rotating plate, and a limiting shaft that slides in cooperation with the arc-shaped limiting groove is fixedly connected to the top of the fixed plate.

[0016] Preferably, the multi-stage radial grease guiding mechanism includes: a spiral groove formed on the inner wall of the central hole, the upper part of the spiral groove communicating with the output end of the follow-up grease delivery mechanism;

[0017] An annular groove is formed in the lower part of the inner wall of the central hole, and a plurality of conveying inclined holes connecting the spiral groove and the annular groove;

[0018] Three coaxially arranged positioning rings with progressively increasing diameters are fixedly connected to the bottom of the rotating plate;

[0019] A positioning groove is formed on the top of the fixing plate for cooperating with the positioning ring;

[0020] A diversion groove is formed in the lower part of the inner wall of the central hole to connect the annular groove and the positioning groove;

[0021] The system includes a main flow channel at the bottom of the positioning ring, a secondary flow channel at the top of the fixed plate that cooperates with the main flow channel for flow guidance, and an arc-shaped grease-leveling channel at the bottom of the rotating plate.

[0022] Preferably, there are six conveying oblique holes, which are equidistantly distributed along the circumference between the spiral groove and the annular groove.

[0023] Preferably, a deep groove ball bearing is fixedly connected to the upper part of the inner wall of the central hole, and the inner ring of the deep groove ball bearing is installed with an interference fit to the surface of the central shaft.

[0025] The top of the rotating plate is provided with a groove, and a retaining ring is movably sleeved on the upper part of the central shaft. The retaining ring is fixedly installed inside the groove. A limit ring is fixedly installed on the top of the central shaft by anti-loosening bolts, and a rubber pad ring is provided at the bottom of the limit ring.

[0026] Preferably, a pressure-type grease drain valve is fixedly connected to the bottom of the fixing plate, and the pressure-type grease drain valve is installed at the bottom of the outermost positioning groove.

[0027] A bushing is fixedly connected to the top of the fixed plate, and a sealing ring that cooperates with the bushing is fixedly connected to the bottom of the rotating plate.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] In this invention, the mounting plate is divided into a fixed plate and a horizontally rotatable rotating plate, and the two are rotatably connected by a central shaft. When the vehicle travels on a road with curves and slopes, the rotating plate can adaptively deflect around the central shaft, so that the center line of the towing seat swing angle is always perpendicular to the center axis of the semi-trailer, avoiding deviation of the vertical load of the trailer and ensuring that the towing tires always have effective grip. This solves problems such as heavy steering, rear wheel lift-off, and power interruption, and greatly improves the overall driving safety of the vehicle.

[0030] In this invention, by equipping a follow-up grease delivery mechanism and a multi-stage radial grease guiding mechanism, the rotating plate can drive the arc-shaped piston cylinder to quantitatively extract grease when it deflects. With the help of spiral grooves, drainage grooves and arc-shaped grease-spreading grooves, the grease can be automatically guided and evenly spread, eliminating lubrication dead corners. At the same time, the pressure-type grease discharge valve can promptly discharge waste grease and impurities, ensuring the grease is clean. There is no need for manual periodic grease replenishment, which significantly reduces wear on mating surfaces, extends the service life of components, and reduces maintenance costs and downtime.

[0031] In this invention, when the spiral groove in the central hole rotates synchronously with the rotating plate, a self-suction effect is generated, which actively adsorbs the grease conveyed by the Y-shaped conveying pipe, assists the use of the arc-shaped piston cylinder, improves the flow dynamics of the grease, and avoids grease stagnation and accumulation. At the same time, the equidistant pitch design of the spiral groove, combined with the six circumferentially distributed conveying oblique holes, can evenly distribute the grease to the annular groove, laying the foundation for subsequent multi-stage flow guidance, ensuring that the grease is evenly distributed on each mating surface, and further improving lubrication reliability.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Please see Figures 1 to 16 This invention provides a technical solution: a horizontally rotatable traction seat mounting plate, comprising: a fixed plate 1, a central shaft 2 detachably mounted on the middle of the fixed plate 1, a rotating plate 3 overlapping the top of the fixed plate 1, and a central hole 4 in the middle of the rotating plate 3 for mounting with the central shaft 2. It should be noted that: a mounting hole is provided at the axial position of the fixed plate 1, the central shaft 2 passes through the mounting hole, and the lower part of the central shaft 2 is mounted to the fixed plate 1 by bolts; the rotating plate 3 is rotatably mounted on the upper part of the central shaft 2 through the central hole 4.

[0051] It also includes a follow-up grease delivery mechanism 5, which is movably installed between the right side of the fixed plate 1 and the rotating plate 3, for delivering grease to the center position of the rotating plate 3.

[0052] A multi-stage radial grease guiding mechanism 6 is disposed between the bottom of the rotating plate 3 and the top of the fixed plate 1 for guiding the flow of lubricating grease.

[0053] In this embodiment, as Figures 1 to 16 As shown, the follow-up fat delivery mechanism 5 includes a Y-shaped connecting pipe 501 fixedly connected to the right side of the rotating plate 3.

[0054] An arc-shaped piston cylinder 502 is symmetrically fixedly connected inside the rotating plate 3. The two ends of the left side of the Y-shaped connecting pipe 501 are respectively connected to the two arc-shaped piston cylinders 502. An arc-shaped piston rod 503 is slidably arranged between the two arc-shaped piston cylinders 502, and a connecting rod 504 is fixedly connected between the middle of the arc-shaped piston rod 503 and the top of the fixed plate 1. It should be noted that the arc-shaped piston rod 503 is a double-ended rod type. The piston ends at both ends of the arc-shaped piston rod 503 are respectively sealed to the two arc-shaped piston cylinders 502. When the arc-shaped piston rod 503 moves inside the two arc-shaped piston cylinders 502, the two arc-shaped piston cylinders 502 draw grease from inside the Y-shaped connecting pipe 501 in a staggered manner.

[0055] A Y-shaped conveying pipe 505 is fixedly connected to the right side of the rotating plate 3 and passes through the central hole 4. The two ends of the right side of the Y-shaped conveying pipe 505 are respectively connected to the output ends of the two arc-shaped piston cylinders 502. It should be noted that a T-shaped pipe is fixedly installed at the right end of the Y-shaped conveying pipe 505, and the Y-shaped conveying pipe 505 is fixedly connected to the conveying ends of the two arc-shaped piston cylinders 502 through the T-shaped pipe.

[0056] In this embodiment, as Figures 1 to 16 As shown, main check valves are installed at both ends of the left side of the Y-type connecting pipe 501, and a grease tank is installed at the right end of the Y-type connecting pipe 501. It should be noted that the main check valves prevent grease inside the Y-type connecting pipe 501 from flowing back into the grease tank. The grease tank is mounted on the tractor frame. During the operation of the follow-up grease delivery mechanism 5, grease is quantitatively drawn through the Y-type connecting pipe 501, with a single relative deflection stroke drawing 0.3-0.6 mL to avoid excessive waste. The Y-type connecting pipe 501 is a flexible hose. The installation and use of the grease tank and the Y-type connecting pipe 501 are existing technologies and will not be described further here.

[0057] In this embodiment, as Figures 1 to 16 As shown, an arc-shaped mounting groove 506 is provided at the bottom right side of the rotating plate 3, and two arc-shaped piston cylinders 502 are respectively installed on both sides of the arc-shaped mounting groove 506.

[0058] A one-way valve is installed at the output end of the arc-shaped piston cylinder 502. It should be noted that the one-way valve is set in the opposite direction to the main one-way valve. When the arc-shaped piston rod 503 moves outward from the arc-shaped piston cylinder 502, the one-way valve closes while the main one-way valve opens, allowing the grease inside the Y-type connecting pipe 501 to enter the arc-shaped piston cylinder 502. Conversely, when the one-way valve opens, the grease inside the arc-shaped piston cylinder 502 enters the Y-type delivery pipe 505 from the position of the one-way valve.

[0059] An arc-shaped limiting groove 507 is provided at the bottom left side of the rotating plate 3, and a limiting shaft 508 that slides in conjunction with the arc-shaped limiting groove 507 is fixedly connected to the top of the fixed plate 1. It should be noted that the maximum deflection angle of the rotating plate 3 is mechanically limited by the cooperation of the arc-shaped limiting groove 507 and the limiting shaft 508, so as to avoid the failure of the connection between the towing seat and the trailer due to excessive deflection of the rotating plate 3, which may lead to the towing seat rotating too much. In addition, hydraulic reset rods are symmetrically hinged between the side of the rotating plate 3 and the side wall of the fixed plate 1, which not only facilitates the return of the rotating plate 3 to the initial horizontal state, but also works with the limiting shaft 508 to limit the maximum deflection angle of the rotating plate 3.

[0060] In this embodiment, as Figures 1 to 16 As shown, the multi-stage radial grease guiding mechanism 6 includes: a spiral groove 601 formed inside the central hole 4, with the upper part of the spiral groove 601 communicating with the end of the Y-shaped delivery pipe 505; an annular groove 602 that mates with the spiral groove 601 is formed on the lower part of the inner wall of the central hole 4; and a delivery inclined hole 603 is formed between the inner wall of the annular groove 602 and the inner wall of the spiral groove 601. It should be noted that the grease discharged into the central hole 4 by the Y-shaped delivery pipe 505 is guided by the spiral groove 601 and the six circumferentially distributed delivery inclined holes 603, and is evenly distributed inside the annular groove 602.

[0061] Three positioning rings 604 are fixedly connected to the bottom of the rotating plate 3 and coaxially arranged with the central hole 4. The diameter of the three positioning rings 604 increases radially outward from the central hole 4. The top of the fixed plate 1 has a positioning groove 605 that cooperates with and limits the positioning rings 604. The lower part of the inner wall of the central hole 4 has a flow-diverting groove 606 that cooperates with the positioning groove 605. It should be noted that the grease inside the ring groove 602 is guided evenly into the connected positioning groove 605 through the flow-diverting groove 606 to lubricate the positioning rings 604 and the positioning groove 605. The cooperation between the main flow groove 607 and the secondary flow groove 608 allows the grease to diffuse between the contact surfaces of the fixed plate 1 and the rotating plate 3.

[0062] Several main drainage grooves 607 are formed at the bottom of the positioning ring 604. A secondary drainage groove 608, which cooperates with the main drainage grooves 607 to guide grease, is formed at the top of the fixed plate 1. An arc-shaped grease-distributing groove 609 is formed at the bottom of the rotating plate 3. It should be noted that both the main drainage grooves 607 and the secondary drainage grooves 608 are arc-shaped grooves, which guide the grease. There are twenty-four arc-shaped grease-distributing grooves 609, which are equidistantly distributed along the circumference at the bottom of the rotating plate 3. This allows the grease inside the main drainage grooves 607 to be evenly distributed to the bottom of the rotating plate 3 after being intercepted during rotation, thus improving the lubrication effect.

[0063] In this embodiment, as Figures 1 to 16As shown, there are six conveying inclined holes 603, which are equidistantly distributed along the circumference between the spiral groove 601 and the annular groove 602.

[0064] In this embodiment, as Figures 1 to 16 As shown, a deep groove ball bearing 610 is fixedly connected to the upper part of the inner wall of the central hole 4, and the inner ring of the deep groove ball bearing 610 is interference-fitted with the surface of the central shaft 2. It should be noted that the deep groove ball bearing 610 is designed to withstand the radial load generated by the deflection of the rotating plate 3 and prevent the central shaft 2 from bending.

[0065] The central shaft 2 is a T-shaped shaft, and a thrust ball bearing 611 is fixedly installed between the step in the middle of the central shaft 2 and the bottom of the rotating plate 3. It should be noted that the upper race of the thrust ball bearing 611 is fixedly connected to the bottom of the rotating plate 3, and the lower race of the thrust ball bearing 611 is fixedly connected to the stepped surface of the central shaft 2. The thrust ball bearing 611 is designed to bear the axial compressive load of the rotating plate 3 and distribute it to the fixed plate 1, without acting on the central shaft 2. Furthermore, the grease inside the central hole 4 can effectively act on the positions of the deep groove ball bearing 610 and the thrust ball bearing 611, thereby improving the service life of the deep groove ball bearing 610 and the thrust ball bearing 611.

[0066] The top of the rotating plate 3 has a recess 612. A retaining ring 613 is movably sleeved on the upper part of the central shaft 2, and the retaining ring 613 is fixedly installed inside the recess 612. A limiting ring 614 is fixedly installed on the top of the central shaft 2 by anti-loosening bolts, and a rubber pad ring is provided at the bottom of the limiting ring 614, with the bottom of the rubber pad ring overlapping the top of the retaining ring 613. It should be noted that the inner diameter of the retaining ring 613 is smaller than the outer diameter of the limiting ring 614, so that the retaining ring 613 and the limiting ring 614 cooperate to form an axial limiting structure, restricting the upward movement of the rotating plate 3. At the same time, combined with the radial constraint of the positioning ring 604 and the positioning groove 605, and the load bearing of the deep groove ball bearing 610 and the thrust ball bearing 611, the rotating plate 3 and the fixed plate 1 are prevented from detaching, ensuring the stability of installation and use.

[0067] In this embodiment, as Figures 1 to 16 As shown, a pressure-type grease drain valve 615 is fixedly connected to the bottom of the fixed plate 1, and the pressure-type grease drain valve 615 is installed at the bottom of the outermost positioning groove 605. It should be noted that during the process of the follow-up grease delivery mechanism 5 quantitatively delivering lubricating grease into the central hole 4, excess lubricating grease is gradually discharged through the pressure-type grease drain valve 615 under pressure. Because the lubricating grease flows slowly to the installation position of the pressure-type grease drain valve 615 by diffusion, the lubricating grease discharged through the pressure-type grease drain valve 615 is waste lubricating grease that has been used multiple times. The pressure-type grease drain valve 615 is existing technology and will not be described in detail.

[0068] A bushing 616 is fixedly connected to the top of the fixed plate 1, and a sealing ring 617 that mates with the bushing 616 is fixedly connected to the bottom of the rotating plate 3. It should be noted that the bushing 616 is a self-lubricating polytetrafluoroethylene bushing, and the sealing ring 617 is a lip-shaped rotary sealing ring made of nitrile rubber coated with polyurethane. The diameters of the bushing 616 and the sealing ring 617 are 1.2 times the diameter of the outermost positioning ring 604. The bushing 616 and the sealing ring 617 work together to seal the contact area between the fixed plate 1 and the rotating plate 3, reducing the impact of dust and foreign matter on the lubricating grease.

[0069] The method of use and advantages of this invention: This horizontally rotatable traction seat mounting plate operates as follows:

[0070] like Figures 1 to 16 As shown, during the equipment assembly stage, the fixed plate 1 is first fastened to the preset mounting surface of the main beam of the tractor vehicle, and then the rotating plate 3 is positioned and fixedly assembled with the traction seat. When the vehicle travels to complex road conditions, especially curves and uphill and downhill combined conditions, the rotating plate 3 can achieve adaptive deflection on the top of the fixed plate 1 through the central shaft 2, ensuring that the tires always maintain effective grip and ensuring the driving stability of the whole vehicle.

[0071] When the rotating plate 3 and the fixed plate 1 are relatively deflected, the rotating plate 3 will synchronously drive the arc-shaped piston cylinder 502 to generate relative displacement with the arc-shaped piston rod 503 on the top connecting rod 504 of the fixed plate 1. This displacement causes the arc-shaped piston rod 503 to form pressure on the inside of the arc-shaped piston cylinder 502, pumping the grease at the Y-shaped connecting pipe 501 into the Y-shaped delivery pipe 505 in a metered manner. The grease flows in a direction along the spiral groove 601 in the central hole 4 in the middle of the rotating plate 3. Under the synergistic effect of the synchronous rotation of the rotating plate 3 and the spiral groove 601, the active pumping and precise directional flow of the grease are realized, achieving uniform distribution of the grease in the transmission path. Subsequently, the conveying inclined hole 603 at the bottom of the spiral groove 601 diverts the grease into the annular groove 602, and then precisely guides it to the mating gap between the corresponding positioning ring 604 and the positioning groove 605 through the diversion groove 606 on the annular groove 602, so that the grease can achieve efficient diffusion in the central area of ​​the rotating plate 3.

[0072] After the grease flows through the gap between the positioning ring 604 and the positioning groove 605, it continues to diffuse outward from the main drainage groove 607 at the bottom of the positioning ring 604, and then diffuses through the drainage groove 608 at the top of the two adjacent positioning grooves 605 to the mating position of the next level positioning ring 604 and positioning groove 605, and diffuses step by step to the inner part of the outermost positioning groove 605, and is finally discharged through the pressure-type grease discharge valve 615.

[0073] During this operation, the positioning ring 604 at the bottom of the rotating plate 3 and the positioning groove 605 at the top of the fixed plate 1 form a precise fit, effectively ensuring the stability of the radial movement of the rotating plate 3 and the fixed plate 1. At the same time, when the rotating plate 3 rotates, it drives the arc-shaped grease distribution groove 609 to rotate synchronously. The arc-shaped grease distribution groove 609 dynamically intercepts the grease in the main drainage groove 607. As the rotating plate 3 continues to rotate, the grease is evenly spread on the contact interface between the bottom of the rotating plate 3 and the top of the fixed plate 1, significantly reducing the relative rotational friction between the two components. In addition, with the help of the step-by-step diffusion of the grease, the impurities and dirt generated by the rotational friction between the rotating plate 3 and the fixed plate 1 can be gradually discharged through the pressure-type grease discharge valve 615 arranged at the bottom of the fixed plate 1 as the grease diffuses, ensuring that the grease is always kept clean and ensuring a long-term stable lubrication effect.
