Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing, and in particular to a reinforced front drive axle for tractors. Background Technology

[0002] The Guhe front drive axle refers to the front drive axle used in agricultural machinery such as tractors. It has a stronger load-bearing capacity and higher durability than conventional front drive axles, and is suitable for more complex and harsh working environments.

[0003] The existing Guhe front drive axle body uses thicker and more durable steel or alloy materials for both the axle housing and support components, giving it a higher load-bearing capacity to withstand heavier loads and harsher working environments. In agricultural mechanized production, when the Guhe front drive axle body is installed on a tractor, the front wheels are fixed to the mounting frame. When the tractor starts, two hydraulic rods on the Guhe front drive axle body extend and retract, pulling the universal joint shaft to steer the mounting frame and front wheels synchronously, meeting the tractor's turning and U-turn needs in the field. However, during long-term, high-intensity operation, the hydraulic rods, as steering power actuators, require frequent reciprocating extension and retraction of their fixed and output rods. The mating surfaces between these rods are prone to wear due to friction, potentially affecting the sealing, efficiency, and service life of the hydraulic rods. Increased wear can lead to a decline in hydraulic system performance, causing problems such as oil leaks and slow response, ultimately affecting the tractor's steering accuracy and operational stability, and increasing maintenance costs. Utility Model Content

[0004] The technical problem this invention aims to solve is that during long-term, high-intensity operation, the hydraulic rod, as a steering power actuator, requires frequent reciprocating extension and retraction movements between its fixed rod and output rod. The mating surfaces between these two rods are prone to wear due to friction, which may affect the sealing performance, efficiency, and service life of the hydraulic rod. Increased wear can lead to a decline in the performance of the hydraulic system, resulting in problems such as oil leaks and slow response, ultimately affecting the steering accuracy and operational stability of the tractor and increasing maintenance costs.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a reinforced front drive axle for tractors, including a front drive axle body, with mounting brackets rotatably installed at both ends of the front drive axle body, and hydraulic rods fixedly installed on both sides of the front drive axle body. A universal joint shaft is fixedly installed on one side of the output rod of the hydraulic rod, and one end of the universal joint shaft is rotatably installed on one side of the mounting bracket. A lubrication device is provided between the hydraulic rod and the front drive axle body. The lubrication device can inject lubricating oil into the oil tank. Then, the electric telescopic rod is activated to drive the piston plate to slide to one end in the inner wall of the oil tank, squeezing the lubricating oil inside into the oil pipe. Then, when the output rod of the hydraulic rod moves back and forth in the inner wall of the fixed rod, it will drive several balls on the ring frame to roll and carry out lubricating oil to coat the outer surface of the output rod of the hydraulic rod, thus performing lubrication and maintenance treatment on its surface.

[0006] Preferably, the lubrication device includes an oil tank, one side of which is fixedly mounted on one side of the front drive axle body; an electric telescopic rod, one side of which is fixedly mounted on one side of the inner wall of the oil tank; a piston plate, which is slidably mounted in the inner wall of the oil tank, and one side is fixedly mounted on the output end of the electric telescopic rod; two ring frames, one side of which is fixedly mounted on one side of the fixed rod of the hydraulic rod, and the inner wall of which is sleeved on the outer surface of the output rod of the hydraulic rod; two oil pipes, the two ends of which are respectively installed through one side of the oil tank and the outer surface of the ring frames; a plurality of ball bearings, which are installed through one side of the inner wall of the ring frames, and the outer surface of which is in rolling contact with the outer surface of the output rod of the hydraulic rod; and a support mechanism, which is disposed on the outer surface of the oil pipes and one side of the front drive axle body, for supporting and reinforcing the outer surface of the oil pipes.

[0007] The effect achieved by the above components is as follows: by setting up a lubrication device, when the main body of the Guhe front drive axle is installed on the tractor in agricultural mechanized production, the front wheels will be fixedly installed on the mounting frame. Then, when the tractor starts, the two hydraulic rods on the main body of the Guhe front drive axle can be activated to extend and retract, pulling the universal joint shaft to drive the mounting frame and the front wheels to turn synchronously, so as to meet the needs of the tractor to turn and turn around in the field. During the operation of the hydraulic rod, the oil tank can be filled with lubricating oil first. When lubrication is needed, the electric telescopic rod fixed to one side of the inner wall of the oil tank is activated. The output end of the electric telescopic rod drives the piston plate to slide to one end, squeezing the lubricating oil inside the oil tank into the oil pipe, and then delivering it to the ring frame. When the output rod of the hydraulic rod moves back and forth in the inner wall of the fixed rod, it will drive several balls on the inner wall of the ring frame to roll, evenly carrying out the lubricating oil inside the ring frame and coating it on the outer surface of the hydraulic rod output rod. This reduces the friction between the output rod and the fixed rod, reduces the resistance when the output rod moves, and makes the hydraulic rod run more smoothly. This can reduce the wear between the hydraulic rod output rod and the fixed rod, improve the service life, avoid affecting the steering accuracy and operational stability of the tractor, and reduce maintenance costs.

[0008] Preferably, the lubrication device further includes several sponge ring blocks, wherein the outer surfaces of the several sponge ring blocks are symmetrically fixed on the inner wall of the ring frame and located on both sides of several balls.

[0009] The effects achieved by the above components are as follows: the sponge ring can absorb excess lubricating oil, preventing lubricating oil from dripping and being wasted due to excessive application. At the same time, when the hydraulic rod output rod moves, the sponge ring can also wipe the surface of the output rod a second time, making the lubricating oil more evenly distributed on the surface of the output rod, further improving the lubrication effect and reducing component wear caused by uneven lubrication.

[0010] Preferably, a cross-shaped silicone valve is fixedly installed on the inner wall of one end of the oil pipe, and the cross-shaped silicone valve is located in the inner wall of the oil pipe near the inlet of the oil tank.

[0011] The effects achieved by the above components are as follows: the cross silicone valve can effectively prevent the lubricating oil that has been delivered to the oil pipe from flowing back to the oil tank, ensuring that the lubricating oil is always delivered to the ring frame, avoiding insufficient lubricating oil supply at the ring frame due to backflow, and ensuring the continuity and stability of lubrication work. At the same time, the cross silicone valve can also close the oil pipe inlet when lubrication is stopped, preventing the lubricating oil in the oil tank from being contaminated by the outside.

[0012] Preferably, a reinforcing rod is symmetrically fixedly installed on the outer surface of the output end of the electric telescopic rod, and one side of the reinforcing rod is fixedly installed on one side of the piston plate.

[0013] The effects achieved by the above components are as follows: the reinforcing rod can enhance the connection strength between the electric telescopic rod and the piston plate, prevent the piston plate from breaking or loosening due to uneven force when the electric telescopic rod drives the piston plate to slide, ensure that the piston plate can always stably follow the movement of the electric telescopic rod, ensure the extrusion and delivery efficiency of lubricating oil, and extend the service life of the electric telescopic rod and the piston plate.

[0014] Preferably, the support mechanism includes a support frame, wherein one side of the support frame is fixedly installed on one side of the front drive axle body; two elastic arc blocks, wherein the outer surface of the elastic arc blocks is fixedly installed on one side of the support frame, and the outer surface of the oil pipe is inserted into the inner wall of the elastic arc blocks.

[0015] The effect achieved by the above components is as follows: by setting up a support mechanism, during installation, the outer surface of the oil pipe can be clamped into the inner wall of the elastic arc block and fixed in place. Then, it is supported and fixed on one side of the main body of the front drive axle by the support frame. This makes it less likely to shake or shift during use, thus improving the stability during use.

[0016] Preferably, limit blocks are fixedly installed at both ends of the elastic arc block, and the limit blocks are fixed at an angle on both sides of the entrance of the elastic arc block.

[0017] The effect achieved by the above components is that the limiting blocks, which are fixedly installed at both ends of the elastic arc block, are fixed at an angle on both sides of the entrance of the elastic arc block. They can play a guiding role during the installation of the oil pipe, making it convenient for the oil pipe to be quickly inserted into the inner wall of the elastic arc block and facilitating installation.

[0018] Preferably, a plurality of anti-slip blocks are fixedly installed on the inner wall of the elastic arc block, and the anti-slip blocks are made of rubber.

[0019] The effect achieved by the above components is that by setting anti-slip blocks, the friction between the outer surface of the oil pipe and the inner wall of the elastic arc block can be increased, effectively preventing the oil pipe from sliding in the inner wall of the elastic arc block, and ensuring the stability of the oil pipe position even when the tractor vibrates violently.

[0020] The beneficial effects of this utility model are:

[0021] By incorporating a lubrication system, the oil tank can be filled with lubricating oil during the operation of the hydraulic rod. When lubrication is needed, the electric telescopic rod fixed to one side of the oil tank is activated. The output end of the electric telescopic rod drives the piston plate to slide to one end, squeezing the lubricating oil inside the oil tank into the oil pipe, and then delivering it to the ring frame. When the output rod of the hydraulic rod moves back and forth in the inner wall of the fixed rod, it drives several balls on the inner wall of the ring frame to roll, evenly carrying out the lubricating oil inside the ring frame and coating it on the outer surface of the hydraulic rod output rod. This reduces the friction between the output rod and the fixed rod, reduces the resistance during the movement of the output rod, and makes the hydraulic rod run more smoothly. This reduces wear between the hydraulic rod output rod and the fixed rod, increases service life, avoids affecting the steering accuracy and operational stability of the tractor, and reduces maintenance costs.

These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0032] Figure 1-6 The reinforced front drive axle for tractors shown includes a main body 1. Mounting brackets 5 are rotatably mounted at both ends of the main body 1. Hydraulic rods 3 are fixedly mounted on both sides of the main body 1. A universal joint shaft 4 is fixedly mounted on one side of the output rod of the hydraulic rod 3. One end of the universal joint shaft 4 is rotatably mounted on one side of the mounting bracket 5. A lubrication device 2 is provided between the hydraulic rod 3 and the main body 1. The lubrication device 2 injects lubricating oil into the oil tank 21. Then, the electric telescopic rod 22 is activated, causing the piston plate 23 to slide to one end within the inner wall of the oil tank 21, squeezing the lubricating oil into the oil pipe 24. As the output rod of the hydraulic rod 3 moves back and forth within the inner wall of the fixed rod, it causes several ball bearings 26 on the ring frame 25 to roll, carrying lubricating oil out and coating the outer surface of the output rod of the hydraulic rod 3, thus lubricating and maintaining its surface. It should be noted that the main body 1 of the front drive axle is a mature technology and equipment in the prior art; its internal structure, connection method, and principle will not be elaborated further.

[0033] Figure 1-6The lubrication device 2 shown includes an oil tank 21, one side of which is fixedly mounted on one side of the front drive axle body 1; an electric telescopic rod 22, one side of which is fixedly mounted on one side of the inner wall of the oil tank 21; a piston plate 23, which is slidably mounted in the inner wall of the oil tank 21, and one side is fixedly mounted on the output end side of the electric telescopic rod 22; and two circular ring frames 25, one side of which is fixedly mounted on one side of the fixed rod of the hydraulic rod 3, and the inner wall is fitted onto... On the outer surface of the output rod of the hydraulic rod 3; two oil pipes 24, with both ends of the oil pipes 24 respectively passing through and installed on one side of the oil tank 21 and the outer surface of the ring frame 25; several ball bearings 26, with several ball bearings 26 passing through and installed on one side of the inner wall of the ring frame 25, and their outer surfaces rollingly connected to the outer surface of the output rod of the hydraulic rod 3; a support mechanism 28, which is set on the outer surface of the oil pipes 24 and one side of the front drive axle body 1, for supporting and reinforcing the outer surface of the oil pipes 24. By setting the lubrication device 2, in agricultural mechanized production, when the front drive axle body 1 is installed on the tractor, the front wheels will be fixedly installed on the mounting frame 5. Then, when the tractor starts, the two hydraulic rods 3 on the front drive axle body 1 can be activated to extend and retract, pulling the universal joint shaft 4 to drive the mounting frame 5 to turn synchronously with the front wheels, so as to meet the needs of the tractor to turn and turn around in the field. During the operation of the hydraulic rod 3, the oil tank 21 can be filled with lubricating oil first. When lubrication is required, the electric telescopic rod 22 fixed on one side of the inner wall of the oil tank 21 is activated. The output end of the electric telescopic rod 22 drives the piston plate 23 to slide to one end, squeezing the lubricating oil inside the oil tank 21 into the oil pipe 24, and then delivering it to the ring frame 25. When the output rod of the hydraulic rod 3 moves back and forth in the inner wall of the fixed rod, it will drive several balls 26 on the inner wall of the ring frame 25 to roll, evenly carrying out the lubricating oil inside the ring frame 25 and coating it on the outer surface of the output rod of the hydraulic rod 3. This reduces the friction between the output rod and the fixed rod, reduces the resistance when the output rod moves, and makes the hydraulic rod 3 run more smoothly. This can reduce the wear between the output rod and the fixed rod of the hydraulic rod 3, improve the service life, avoid affecting the steering accuracy and operational stability of the tractor, and reduce maintenance costs.

[0034] Figure 1-6The lubrication device 2 shown also includes several sponge rings 27, the outer surfaces of which are symmetrically fixed on the inner wall of the ring frame 25 and located on both sides of several balls 26. The sponge rings 27 can absorb excess lubricating oil, preventing it from dripping and being wasted due to excessive application. Simultaneously, when the hydraulic rod 3 output rod moves, the sponge rings 27 can also perform a secondary wiping of the output rod surface, making the lubricating oil more evenly distributed on the output rod surface, further improving the lubrication effect and reducing component wear caused by uneven lubrication. A cross-shaped silicone valve 29 is fixedly installed on the inner wall of one end of the oil pipe 24, located on the inner wall of the oil pipe 24 near the inlet of the oil tank 21. The cross-shaped silicone valve 29 effectively prevents the lubricating oil delivered to the oil pipe 24 from flowing back to the oil tank 21, ensuring that the lubricating oil is always delivered towards the ring frame 25. This avoids insufficient lubricating oil supply at the ring frame 25 due to backflow, ensuring the continuity and stability of lubrication work. Simultaneously, the cross-shaped silicone valve 29 can also close the inlet of the oil pipe 24 when lubrication stops, preventing the lubricating oil in the oil tank 21 from being contaminated by external sources. Reinforcing rods 210 are symmetrically fixed to the outer surface of the output end of the electric telescopic rod 22, with one side of the reinforcing rod 210 fixedly mounted on one side of the piston plate 23. The reinforcing rod 210 enhances the connection strength between the electric telescopic rod 22 and the piston plate 23, preventing breakage or loosening of the connection between the piston plate 23 and the electric telescopic rod 22 due to uneven force when the electric telescopic rod 22 drives the piston plate 23 to slide. This ensures that the piston plate 23 can always stably follow the movement of the electric telescopic rod 22, guaranteeing the efficiency of lubricating oil extrusion and delivery, and extending the service life of the electric telescopic rod 22 and the piston plate 23.

[0035] Figure 1-6 The support mechanism 28 shown includes a support frame 281, one side of which is fixedly mounted on one side of the front drive axle body 1; and two elastic arc blocks 282, the outer surfaces of which are fixedly mounted on one side of the support frame 281, and the outer surface of the oil pipe 24 is inserted into the inner wall of the elastic arc block 282. By setting up the support mechanism 28, during installation, the outer surface of the oil pipe 24 can be inserted into the inner wall of the elastic arc block 282 for limiting and fixing, and then it is supported and fixed on one side of the front drive axle body 1 by the support frame 281. This makes it less prone to shaking or displacement during use, improving stability during use.

[0036] Figure 1-6Both ends of the elastic arc block 282 shown are fixedly equipped with limiting blocks 283, which are inclinedly fixed on both sides of the entrance of the elastic arc block 282. The limiting blocks 283, fixedly installed at both ends of the elastic arc block 282 at an inclined angle, serve as a guide during the installation of the oil pipe 24, facilitating the quick insertion of the oil pipe 24 into the inner wall of the elastic arc block 282. Several anti-slip blocks 284, made of rubber, are fixedly installed on the inner wall of the elastic arc block 282. By setting the anti-slip blocks 284, the friction between the outer surface of the oil pipe 24 and the inner wall of the elastic arc block 282 is increased, effectively preventing the oil pipe 24 from sliding within the inner wall of the elastic arc block 282, ensuring the stability of the oil pipe 24 even during severe vibrations of the tractor.

[0037] Working Principle: The existing Guhe front drive axle body 1 uses thicker and more durable steel or alloy materials for both the axle housing and support components, giving it a higher load-bearing capacity and enabling it to cope with higher loads and harsh working environments. In agricultural mechanized production, when the Guhe front drive axle body 1 is installed on a tractor, the front wheels are fixedly mounted on the mounting frame 5. When the tractor starts, the two hydraulic rods 3 on the Guhe front drive axle body 1 can be extended or retracted, pulling the universal joint shaft 4 to drive the mounting frame 5 to steer synchronously with the front wheels, thus meeting the tractor's needs for turning and U-turns in the field. During the operation of the hydraulic rod 3, the oil tank 21 can be filled with lubricating oil first. When lubrication is needed, the electric telescopic rod 22 fixed on one side of the inner wall of the oil tank 21 is activated. The output end of the electric telescopic rod 22 drives the piston plate 23 to slide to one end, squeezing the lubricating oil inside the oil tank 21 into the oil pipe 24 and squeezing open the cross silicone valve 29, ensuring that the lubricating oil is stably delivered to the ring frame 25 in one direction. When the output rod of the hydraulic rod 3 moves back and forth in the inner wall of the fixed rod, it will drive several balls 26 on the inner wall of the ring frame 25 to roll, evenly carrying the lubricating oil inside the ring frame 25. The lubricant is applied to the outer surface of the output rod of the hydraulic rod 3, reducing friction between the output rod and the fixed rod. This also reduces resistance during the movement of the output rod, making the hydraulic rod 3 run more smoothly. At the same time, the sponge rings 27, which are symmetrically fixed to the inner wall of the ring frame 25 and located on both sides of the ball bearings 26, can absorb excess lubricant, preventing lubricant waste. They can also perform a secondary wipe on the surface of the output rod, ensuring a more uniform lubrication effect. This reduces wear between the output rod and the fixed rod of the hydraulic rod 3, increases service life, avoids affecting the steering accuracy and operational stability of the tractor, and reduces maintenance costs.

[0038] To prevent the oil pipe 24 from shifting or being damaged due to vibration or external force during operation, during installation, the outer surface of the oil pipe 24 can be inserted into the inner wall of the elastic arc block 282, and fixed by the anti-slip block 284. Then, it is supported and fixed to one side of the front drive axle body 1 by the support frame 281. This makes it less likely to shake or shift during use, thus improving stability during use.

[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
