Description

Technical Field

[0001] This utility model belongs to the field of truck parts repair technology, specifically relating to a truck steering knuckle disassembly device. Background Technology

[0002] The steering knuckle, also known as the "steering knuckle," is a critical safety component of the truck's steering system. Its core function is to precisely transmit the steering torque from the driver through the steering system to the wheels, thereby enabling the vehicle's steering function. It also bears a portion of the vehicle's weight and impact loads generated during driving, making it crucial for ensuring the truck's handling stability and driving safety. With the continuous development of the truck industry, to meet the demands for higher transportation efficiency, trucks are constantly improving their load-bearing capacity, operational performance, and automation levels. Correspondingly, as a key load-bearing component, the manufacturing technology of the steering knuckle is also constantly iterating and updating, moving towards more complex structures, higher material strength, and greater manufacturing precision to ensure higher safety, load-bearing capacity, durability, and lightweight design. However, the enhanced technical performance of the steering knuckle has also led to tighter fits and greater connection strength in its structural components (such as kingpin holes and bearing mounting positions). While this trend improves product performance, it also brings significant maintenance challenges. During the long-term use of trucks, the steering knuckle inevitably experiences wear and deformation due to alternating stress, impact loads, and environmental corrosion, requiring replacement or repair. Currently, the repair of faulty steering knuckles mainly relies on traditional manual disassembly and installation methods. This method has many drawbacks: First, the steering knuckle itself is heavy, and its connections with adjacent components (such as the kingpin, brake backing plate, and wheel hub) are often interference fits or severely corroded, making the disassembly process extremely difficult. Repair personnel must expend considerable physical strength, using primitive methods such as hammering with sledgehammers and prying with crowbars, resulting in low work efficiency. Second, rough manual handling can easily damage the delicate steering knuckle body, increasing repair costs, and may even affect the positioning accuracy after reassembly, thus impacting the vehicle's steering performance and four-wheel alignment parameters.

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] This embodiment provides a truck steering knuckle removal device. Figure 1 This is a three-dimensional structural diagram of the truck steering knuckle removal device in this embodiment. Figure 2 This is a schematic diagram of the structure of the mobile chassis 1 in this embodiment. Figure 3This is a schematic diagram showing the positional relationship between the sliding frame 2, the hub clamping mechanism 3, the bolt clamping mechanism 4, and the pin disassembly mechanism 5 in this embodiment.

[0022] like Figures 1-3 As shown, the truck steering knuckle removal device of this embodiment includes: a mobile chassis 1, a sliding frame 2, a hub clamping mechanism 3, a bolt clamping mechanism 4, and a pin removal mechanism 5. The mobile chassis 1 includes a guide rail 11 and a support structure 12. The support structure 12 is located near one end of the guide rail 11 along its length. The support structure 12 supports the truck steering knuckle. The sliding frame 2 is slidably mounted on the guide rail 11. The hub clamping mechanism 3 is vertically mounted on the sliding frame 2. The hub clamping mechanism 3 clamps the outer circumference of the steering knuckle hub. The bolt clamping mechanism 4 is vertically mounted on the sliding frame 2. The bolt clamping mechanism 4 is located on the side of the hub clamping mechanism 3 away from the support structure 12. The bolt clamping mechanism 4 is used to fix the bolts at the front end of the steering knuckle hub. The pin removal mechanism 5 is located at the top of the sliding frame 2. The pin removal mechanism 5 is used to remove the main pin of the truck steering knuckle.

[0023] When a steering knuckle assembly of a mining truck malfunctions, the truck steering knuckle disassembly device is moved to the disassembly target location via a mobile chassis 1. During disassembly, the bottom of the truck steering knuckle assembly is supported by a support structure 12, ensuring the steering knuckle is at the same height as the wheel hub center. Then, the sliding frame 2 moves the wheel hub clamping mechanism 3, bolt clamping mechanism 4, and pin removal mechanism 5 along the guide rail 11, adjusting the height of the wheel hub clamping mechanism 3 to clamp onto the outer circumference of the wheel hub, thus fixing the wheel hub. Next, the position of the bolt clamping mechanism 4 is adjusted so that it is fixed to the bolts at the front end of the wheel hub for positioning. Finally, the position of the pin removal mechanism 5 is adjusted so that it is positioned above the main pin of the truck steering knuckle, and the main pin is disassembled. Using the truck steering knuckle disassembly device of this embodiment improves disassembly efficiency, reduces labor intensity, lowers safety risks, and avoids damage to the truck steering knuckle components during disassembly.

[0024] Among them, such as Figure 2 As shown, the mobile chassis 1 includes: a chassis frame 13, a tracked walking device 14, and a powertrain 15. The chassis frame 13 is mounted on the tracked walking device 14. A guide rail 11 and a support structure 12 are mounted on the chassis frame 13. The powertrain 15 is mounted on the chassis frame 13, and the powertrain 15 is located near the end of the guide rail 11 that is furthest from the support structure 12. The powertrain 15 is connected to the tracked walking device 14.

[0025] The tracked walking device 14 of this embodiment mainly includes a track frame, drive wheels, track rollers, carrier rollers, tension rollers, tracks, and walking drive elements. When the device needs to move, the power unit 15 is activated to provide power to the walking drive elements. Through the cooperation of the drive wheels, track rollers, carrier rollers, and tension rollers, the tracks move, thereby realizing walking.

[0026] When the mining truck needs to repair its steering knuckle, under the control of the operator, the powertrain 15 supplies power (electricity or hydraulic) to the tracked walking device 14, driving the tracked walking device 14 to move, which in turn causes the mobile chassis 1 to move the entire truck steering knuckle disassembly device towards the disassembly target. It is understood that the wheel hub clamping mechanism 3, bolt clamping mechanism 4, and pin shaft disassembly mechanism 5 in this embodiment can also be powered (electricity or hydraulic) by the powertrain 15.

[0027] In this embodiment, the mobile chassis 1 is driven by a tracked walking device 14, which has a large ground contact area and low specific pressure. This allows the device to move easily and remain extremely stable when carrying heavy steering knuckles, preventing overturning and avoiding damage to the ground. It is particularly suitable for maneuvering and precise positioning in spaces with limited space and complex ground conditions.

[0028] Among them, such as Figure 1 and Figure 2 As shown, the support structure 12 includes a pair of support components. The pair of support components are symmetrically arranged on both sides of the top of the movable chassis 1. Each support component includes a support column 121, a support arm 122, a support cylinder, and a pressure sensor. The support column 121 is vertically mounted on the movable chassis 1. A guide groove 123 is provided on the support column 121. The guide groove 123 extends along the height of the support column 121. The support arm 122 is vertically and flexibly positioned within the guide groove 123. The piston rod of the support cylinder is connected to the support arm 122 to drive the support arm 122 to move along the guide groove 123. The pressure sensor is used to monitor the pressure exerted on the support arm 122.

[0029] The inclined setting of the support arm 122 in this embodiment is beneficial for insertion into the bottom of the steering knuckle and has a certain limiting effect on the steering knuckle.

[0030] When the support structure 12 of this embodiment is working, the support cylinder actuates to lift the support arm 122, and the support status is monitored in real time using a pressure sensor. When it contacts the bottom of the steering knuckle assembly and reaches the predetermined pressure value, it indicates that the support arm 122 has been lifted to the bottom of the steering knuckle. It continues to rise to a position roughly horizontal with the center of the truck wheel hub and stops moving, ensuring that the steering knuckle assembly is firmly lifted, forming a stable working reference, avoiding component shaking during disassembly and assembly, and providing a basis for precise force application for the pin disassembly mechanism, ensuring the smooth progress of disassembly and assembly operations.

[0031] Among them, such as Figure 1and Figure 3 As shown, the sliding frame 2 includes a connecting beam 21 and a pair of sliding struts 22. Each sliding strut 22 is mounted on a guide rail 11. Each sliding strut 22 includes a first guide rail 23 and a second guide rail 24. The first guide rail 23 is located on the side of the sliding strut 22 facing the center of the moving chassis 1. The second guide rail 24 is located on the side of the sliding strut 22 away from the supporting structure 12. The connecting beam 21 connects the pair of sliding struts 22. A hub clamping mechanism 3 is vertically and heightably mounted on the first guide rail 23. A bolt clamping mechanism 4 is vertically and heightably mounted on the second guide rail 24.

[0032] In this embodiment, the sliding frame 2 is provided with a first guide rail 23 and a second guide rail 24 for mounting the hub clamping mechanism 3 and the bolt clamping mechanism 4, realizing a modular layout and a more reasonable spatial layout, thus avoiding interference.

[0033] Figure 4 This is a schematic diagram of the hub clamping mechanism 3 and the bolt clamping mechanism 4 in this embodiment. Wherein, as shown... Figure 3 and Figure 4 As shown, the hub clamping mechanism 3 includes: a lifting slider 31, a first telescopic rod 32, and a claw 33. The lifting slider 31 is mounted on the first guide rail 13. One end of the first telescopic rod 32 is connected to the lifting slider 31. The claw 33 is mounted on the free end of the first telescopic rod 32.

[0034] In this embodiment, the chuck 33 is a hydraulic chuck, which is safe and quick to operate and can stably clamp and fix the wheel hub.

[0035] The lifting slider 31 in this embodiment can be hydraulically driven or electrically driven, and this embodiment does not impose many restrictions on it.

[0036] The first telescopic rod 32 in this embodiment can be hydraulically or electrically driven; this embodiment does not impose many restrictions on this. By controlling the extension and retraction of the first telescopic rod 32 and adjusting the distance between the two pawls 33, it can be used to disassemble steering knuckles of different sizes, making it convenient, flexible, and widely applicable.

[0037] Among them, such as Figure 3 and Figure 4As shown, the bolt clamping mechanism 4 includes: a support slider 41, a lifting cylinder 42, a second telescopic rod 43, a support beam 44, and multiple bolt connectors 45. The support slider 41 is mounted on the second guide rail 24. The lifting cylinder 42 is located below the support slider 41. The base of the lifting cylinder 42 is connected to the sliding support column 22. The piston rod of the lifting cylinder 42 is connected to the bottom of the support slider 41. One end of the second telescopic rod 43 is connected to the support slider 41. The support beam 44 is arc-shaped. The support beam 44 is located at the free end of the second telescopic rod 42. Multiple bolt connectors 45 are spaced apart on the support beam 44. An elongated hole 46 is provided at the end of each bolt connector 45 away from the support beam 44. The elongated hole 46 is used to fix the bolts at the front end of the steering knuckle hub.

[0038] The support slider 41 in this embodiment is designed with a telescopic structure. By controlling the extension and retraction of the support slider, the support beam can be moved away from or closer to the wheel hub clamping mechanism, so as to adjust the distance between the support beam and the wheel hub clamping mechanism to suit different wheel hubs.

[0039] The support beam 44 in this embodiment is arc-shaped, which can be adapted to the layout of the bolts on the wheel hub, ensuring that the bolt connector 45 is smoothly connected to the bolts at the front end of the steering knuckle wheel hub.

[0040] The bolt connector 45 of this embodiment has an elongated hole 46 at the end away from the support beam. The use of the elongated hole 46 allows for a certain installation margin, which facilitates the connection and fixing of the bolt.

[0041] The bolt clamping mechanism 4 of this embodiment can achieve circumferential and axial positioning of the wheel hub. It works in conjunction with the wheel hub clamping mechanism 3 to form a three-dimensional clamping mechanism, ensuring the stability of the steering knuckle assembly under extreme stress when the steering knuckle kingpin is disassembled, avoiding circumferential torsion and axial movement, and preventing damage to the components.

[0042] Figure 5 This is a schematic diagram of the pin disassembly mechanism 5 in this embodiment. Wherein, as... Figure 1 , Figure 3 and Figure 5 As shown, the pivot pin removal mechanism 5 includes: a support beam 51, a rotating structure 52, a third telescopic rod 53, a lifting structure 54, and a robotic arm 55. The support beam 51 is mounted on the top of the sliding frame 2. The rotating structure 52 is mounted on the support beam 51. One end of the third telescopic rod 53 is connected to the rotating structure 52. The third telescopic rod 53 can rotate with the rotating structure 52. The lifting structure 54 is located at the free end of the third telescopic rod 53. The robotic arm 55 is mounted on the lifting structure 54. The robotic arm 55 can rise and fall with the lifting structure 54. The robotic arm 55 is used to remove the main pivot pin of the truck steering knuckle.

[0043] The robotic arm 55 of this embodiment adopts existing technology. When it is necessary to disassemble the kingpin, the rotating structure 52, the third telescopic rod 53, and the lifting structure 54 work together to drive the robotic arm 55 to move directly above the faulty steering knuckle kingpin. Subsequently, the lifting structure 54 drives the robotic arm 55 to descend, so that the robotic arm 55 firmly grips the kingpin. Then, the upward lifting action of the lifting structure 54 can smoothly pull out the kingpin. The kingpin disassembly mechanism 5 of this embodiment has three degrees of freedom in different directions through the cooperation of the rotating structure 52, the third telescopic rod 53, and the lifting structure 54, which can be applied to the disassembly of steering knuckles of different specifications, making it flexible and widely applicable.

[0044] Among them, such as Figure 3 and Figure 5 As shown, the rotating structure 52 includes a base 521 and a rotating seat 522. The base 521 is mounted on the supporting top beam 51. The rotating seat 522 is rotatably mounted on the base 521. A third telescopic rod 53 is connected to the rotating seat 522.

[0045] The rotating base 522 of this embodiment can rotate on the base 521, thereby driving the robot arm 55 to move around the axis of the base 521, so as to adjust the position and angle of the robot arm 55.

[0046] Among them, such as Figure 3 and Figure 5 As shown, the lifting structure 54 includes: a connecting block 541, a lifting block 542, and a linear drive device. The connecting block 541 is disposed at the free end of the third telescopic rod 53. A lifting slide 543 is provided on the connecting block 541. The lifting block 542 is disposed on the lifting slide 543. The linear drive device is used to drive the lifting block 542 to move along the lifting slide 543. A robotic arm 55 is disposed on the lifting block 542.

[0047] This embodiment uses a linear drive device to drive the lifting block 542 to move along the lifting slide 543, thereby adjusting the height of the robot arm 55, which has the advantages of rapid response and high flexibility.

[0048] The truck steering knuckle removal device also includes a control system. The control system is connected to the mobile chassis 1, the skid steer frame 2, the wheel hub clamping mechanism 3, the bolt clamping mechanism 4, and the pin removal mechanism 5.

[0049] The truck steering knuckle removal device in this embodiment also includes a control system, which enables coordinated control of the mobile chassis 1, the sliding frame 2, the wheel hub clamping mechanism 3, the bolt clamping mechanism 4, and the pin removal mechanism 5, resulting in a higher degree of automation.

[0050] The workflow of the truck steering knuckle removal device implemented here is as follows: (1) Positioning and initial positioning: When the mining truck needs to repair the steering knuckle, the device is activated under the remote or local control of the operator. The powertrain 15 supplies power / oil to the tracked walking device 14, driving the tracked walking device 14 to move its tracks. The tracked chassis enables it to move flexibly and smoothly on the ground, accurately moving to the vicinity of the wheels of the faulty vehicle to complete a wide range of positioning.

[0051] (2) Precise support and leveling: After positioning, the support assembly 12 begins to work. The support cylinder actuates, automatically raising and lowering the support arm 122 to a position approximately horizontal with the center of the truck wheel hub, depending on the type of steering knuckle. The pressure sensor monitors the support status in real time. When it contacts the bottom of the steering knuckle assembly and reaches the predetermined pressure value, it stops moving, ensuring that the steering knuckle assembly is firmly supported, forming a stable working reference and preventing the components from shaking during disassembly and assembly.

[0052] (3) Clamping and fixing of steering knuckle: After the support structure 12 is stably supported, the sliding frame 2 starts to move. At the same time, the hub clamping mechanism 3 and the bolt clamping mechanism 4 adjust their own posture: make the claw 33 accurately close to the hub of the steering knuckle assembly, and lock and fix it; make the support beam 44 consistent with the height of the front bolt of the hub, and make the bolt connector 45 correspond to the position of the bolt, put the elongated hole 46 on the corresponding bolt, and fix it with a nut; make the steering knuckle and this device rigidly connected as one.

[0053] (4) Disassembly of the main pin: After the steering knuckle is firmly clamped, the main pin disassembly mechanism 5 starts to operate. Its rotating structure 52, third telescopic rod 53, and lifting structure 54 are coordinated to drive the robot arm 55 to move directly above the main pin. The robot arm 55 descends and grabs the main pin, and then applies an upward pulling force (or combined with auxiliary impact) to smoothly pull the main pin out of the steering knuckle pin hole, completing the disassembly. (It can be understood that the device in this embodiment can also be used for the installation of the main pin, and the installation process is reversed: the device first clamps the new steering knuckle main pin, adjusts it to the installation position and aligns it with the pin hole. Then, the robot arm 55 clamps the new main pin, and through the coordinated adjustment of the rotating structure 52, third telescopic rod 53, and lifting structure 54, after aligning it with the pin hole, applies a precise pressing force to press the main pin into place.) (5) Reset and withdrawal: After the operation is completed, each actuator is reset in the reverse order (release the chuck 33, retract the support arm 122, and remove the robot arm 55), and the device can leave the work area to carry out the next operation or return to the parking position.

[0054] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0055] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above are only preferred embodiments of this utility model.
