Description

Technical Field

[0001] The utility model relates to the technical field of crawler vehicles, in particular to a maglev crawler vehicle driven by a linear motor. Background Technique

[0002] Crawler vehicles have the advantages of small unit pressure on the ground, strong grip, good cross-country performance and strong passing performance, and are widely used in various construction machinery and agricultural machinery. In the prior art, the chassis and the vehicle body of the crawler vehicle are usually rigidly connected, and only steel springs are provided for vibration isolation at the connection between the crawler wheel set and the chassis. However, the damping of ordinary steel springs is small, and the vibration damping effect on external disturbances such as uneven road surfaces is poor. Moreover, crawler vehicles are mostly used in complex and harsh terrain environments with poor road smoothness, both of which result in relatively intense vibrations transmitted to the crawler vehicle body, significantly affecting the riding comfort and operation quality of the crawler vehicle. In addition, crawler vehicles mostly use internal combustion engines or electric motors to output torque and drive the crawlers to move forward through transmission mechanisms. During the movement process, due to large frictional losses, the power consumption is large, the transmission components are easily damaged, the energy use efficiency is reduced, and the later operation and maintenance costs are increased.

[0003] Although the concept of maglev has been applied to crawler vehicles in the prior art, for example, the patent with the publication number CN105857111A and the name of a new type of suspension propulsion two-in-one maglev system discloses that magnetic interaction is generated between the crawler magnet and the lane aluminum plate to make the vehicle body suspended. However, this kind of suspension requires the vehicle body to move first to generate the suspension force, which is not conducive to energy conservation and the stable operation of the vehicle body.

[0004] In the patent with the publication number CN 101209676 B and the patent name of "Magnetic Levitation Crawler-Type Linear Motor Electrically Driven Vehicle", a suspension system with adjustable suspension force is disclosed. Specifically, permanent magnets are laid on the inner surface of the crawler, and permanent magnets with the same polarity are installed at the frame position opposite to the permanent magnets on the crawler. An array of permanent magnets and electromagnets with adjustable current constitute the suspension system with adjustable suspension force. The composition of the drive system is also disclosed: a crawler is provided on each side of the frame, and the drive system is composed of left and right linear motors with the electromagnetic coils fixed to the frame as the primary and the composite plates (linear motor secondary) embedded in the crawler as the secondary. Although this patent discloses the use of an electromagnetic and permanent magnet hybrid suspension system, where the permanent magnets provide the basic suspension force and the electromagnets provide the controllable suspension force. Due to the effect of magnetic levitation, the frame is separated from the vibrating part, and the electromagnetic force can be adjusted as needed to make the suspension system adapt to the requirements of different road conditions, improving the driving smoothness and performance of the vehicle. However, in this patent, the suspension force is provided by permanent magnets and electromagnets. This magnetic levitation structure uses a relatively large number of permanent magnets, and to meet the purpose of adjustable suspension position of the vehicle, an external electromagnetic controller is required, increasing the weight and load of the whole vehicle. The suspension system of this patent requires a large number of permanent magnets to provide suspension force, resulting in a relatively high cost for the whole vehicle. The adjustable suspension position of this patent is generated by the interaction between the electromagnet and the permanent magnet, and the control of the electromagnet has high requirements for timeliness and control accuracy, and at the same time, the energy consumption is high, affecting the endurance of the whole vehicle.

[0005] Based on the problems existing in the above-mentioned existing patents, it is necessary to study a magnetic levitation crawler vehicle with less energy consumption and smoother operation. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the existing magnetic levitation crawler vehicles have large energy consumption, high cost and poor running smoothness.

[0007] This utility model is realized through the following technical solutions:

[0008] A magnetic levitation crawler vehicle driven by a linear motor, comprising:

[0009] Vehicle body;

[0010] Frame;

[0011] Linear electric drive system;

[0012] Magnetic levitation system;

[0013] Crawler belt driving the vehicle body to move;

[0014] The linear electric drive system includes a plurality of primary windings arranged on the lower side of the vehicle body and a plurality of secondary magnetic pieces arranged on the crawler belt, and the primary windings and the secondary magnetic pieces interact to propel the crawler belt to move;

[0015] The magnetic levitation system includes at least one electromagnetic track provided on the vehicle body and a magnetic track provided on the inner side of the vehicle frame. The electromagnetic track and the magnetic track interact with each other to levitate the vehicle body.

[0016] The vehicle frame is provided with wheel bodies, and the wheel bodies are in rolling connection with the crawler belt.

[0017] In the utility model, a primary winding is arranged on the lower side of the vehicle body, and a secondary magnetic sheet is arranged on the crawler belt corresponding to the primary winding. The primary winding on the lower side of the vehicle body and the secondary magnetic sheet on the crawler belt form a linear electric drive system. The primary winding and the secondary magnetic sheet interact with each other to push the secondary magnetic sheet to move, thereby pushing the crawler belt to move and realizing the propulsion of the vehicle body. By arranging an electromagnetic track on the vehicle body and correspondingly arranging a magnetic track on the inner side of the vehicle frame, the electromagnetic track and the magnetic track form a magnetic levitation system. Relying on the suction force generated between the electromagnetic track and the magnetic track, the levitation of the vehicle body is realized. Through the combined action of the linear electric drive system and the magnetic levitation system, the vibration of the vehicle body is effectively reduced, the riding comfort is improved, the energy utilization rate is increased by adopting the linear motor drive, the mechanical loss is reduced, the vehicle body is levitated relative to the vehicle frame, the friction is further reduced, the mechanical wear is reduced, and the operation efficiency is improved.

[0018] Further, the vehicle frame includes an upper support plate, a bottom frame is connected below the upper support plate, the magnetic track is arranged on the bottom surface of the upper support plate, one end of the electromagnetic track arranged on the vehicle body is sleeved inside the vehicle frame, and the electromagnetic track corresponds to the magnetic track. The primary winding passes downward through the bottom frame and corresponds to the secondary magnetic sheet.

[0019] After adopting this technical solution, it should be noted that the bottom frame includes two side plates and two connecting plates. The two side plates are connected by the two connecting plates. The upper support plate, the side plates and the connecting plates enclose the frame structure of the vehicle frame. The primary winding passes through between the two connecting plates. In addition, it should be noted that the side plates are T-shaped, and the whole vehicle frame is T-shaped. The magnetic track is arranged on the bottom surface of the upper support plate. Subsequently, the wheel bodies are installed on both sides of the lower end of the T-shaped vehicle frame through the connecting plates, so that the wheel bodies are located in the recess of the T-shaped structure, and the vehicle body is sleeved in the frame structure of the vehicle frame enclosed by the upper support plate, the side plates and the connecting plates, making full use of the space, making the whole chassis structure compact, reducing the chassis volume, reducing the mass, and being more energy-saving. In addition, the linear electric drive system and the magnetic levitation system are respectively located at the upper and lower ends of the vehicle body. The interference between the linear electric drive system and the magnetic levitation system is blocked by the vehicle body, improving the operation efficiency of the tracked vehicle and reducing the energy loss.

[0020] In addition, it should be noted that the vehicle body of the utility model includes a base and a body part, and the electromagnetic track is arranged on the base.

[0021] Further, the wheel body includes load wheels and support wheels. The load wheels are provided on at least one side of the bottom frame, and the support wheels are provided at the upper end of the upper support plate. Both the load wheels and the support wheels are in rolling connection with the inner side of the crawler belt.

[0022] Further, a number of rows of support rods are transversely arranged on the upper surface of the upper support plate. Each row of support rods forms two sets of support members. One set of support members includes two support rods, and a support wheel is connected between the two support rods. The distance between the support wheels of the two sets of support members in each row is equal to the distance between the two corresponding load wheels.

[0023] Further, a plurality of the secondary magnetic chips are evenly distributed inside or on the inner surface of the crawler belt. At least one side of the crawler belt is provided with limiting teeth, and a plurality of the limiting teeth form a tooth track, and the load wheels cooperate with the tooth track.

[0024] After adopting the technical solution, it should be noted that the secondary magnetic chips are arranged on the inner surface of the crawler belt through an adhesive.

[0025] The present utility model preferably relates to a maglev crawler vehicle driven by a linear motor. A plurality of the secondary magnetic chips are evenly distributed inside the crawler belt. At least one end of each of the secondary magnetic chips is connected with a limiting tooth 6 through a connecting rod 5, and the limiting tooth 6 penetrates through the crawler belt 8 towards the inner side of the crawler belt 8.

[0026] The present utility model preferably relates to a maglev crawler vehicle driven by a linear motor. Load wheels are arranged on both sides of the bottom frame. Both ends of the secondary magnetic chips are connected with limiting teeth through connecting rods. A plurality of the limiting teeth form two tooth tracks, and the two load wheels respectively cooperate with the two tooth tracks. The secondary magnetic chips are located between the two tooth tracks.

[0027] After adopting this technical solution, it should be noted that by arranging two tooth tracks and arranging load wheels on both sides of the bottom frame, the stability of the crawler belt during movement is improved. The secondary magnetic chips are embedded inside the crawler belt. Embedding the secondary magnetic chips inside the crawler belt, on the one hand, enhances the stability of the secondary magnetic chips, making the secondary magnetic chips not easily interfered with and damaged by the external environment. On the other hand, the stability of the secondary magnetic chips enables the primary winding to achieve good interaction with it in any environment or road condition, ensuring the stable movement of the crawler belt;

[0028] Secondly, it should be noted that in order to better limit the load wheels and support wheels laterally, prevent the crawler from generating lateral offset, and better ensure the stability of the crawler operation, a limiting groove is provided circumferentially on each load wheel and support wheel. The distance between the two tooth rails is the same as the distance between the corresponding limiting grooves on two load wheels or support wheels. Therefore, during the movement of the crawler, the tooth rails will cooperate with the corresponding limiting grooves to achieve lateral limitation of the crawler; and limiting teeth are provided at both ends of the secondary magnetic sheet to form two tooth rails, improving the stability during the operation of the crawler;

[0029] Furthermore, the load wheel is made of low-carbon steel material, so that the load wheel has the function of shielding the magnetic field.

[0030] Furthermore, the side surface of the load wheel is coated with materials with high magnetic permeability and resistivity such as silicon steel sheet particles or soft ferrite to achieve the magnetic shielding effect.

[0031] The present utility model preferably relates to a linear motor-driven maglev crawler vehicle. Electromagnetic tracks are respectively provided on the upper surfaces at both ends of the vehicle body, and both ends of the vehicle body are respectively sleeved in two of the vehicle frames.

[0032] After adopting this technical solution, it should be noted that by providing electromagnetic tracks at both ends of the vehicle body and sleeving vehicle frames at both ends of the vehicle body and corresponding to the magnetic tracks, crawlers are provided at both ends of the vehicle body subsequently. On the one hand, the overall passability of the crawler vehicle is improved, and the application range is wider. On the other hand, the vehicle body is also made more stable.

[0033] The present utility model preferably relates to a linear motor-driven maglev crawler vehicle. A raised iron core is provided at the lower end of the vehicle body corresponding to the electromagnetic track. The primary winding is wound around the raised iron core, and the raised iron core penetrates between two of the bottom frames.

[0034] After adopting this technical solution, it should be noted that since the raised iron core penetrates into the bottom frame, that is, between two connecting plates, due to the limitation of the two connecting plates, the position and swing of the raised iron core can be limited laterally, so that the electromagnetic track and the magnetic track can always be kept corresponding and generate a stable levitation force to levitate the vehicle body, further reducing mechanical friction and improving the service life of the device.

[0035] The present utility model preferably relates to a linear motor-driven maglev crawler vehicle. A tension support system is provided between the crawlers. The tension support system includes a tension wheel, a telescopic assembly and a rotating table. The tension wheel is in contact support connection with the crawler. The rotating table is arranged on the support plate, and the tension wheel is connected to the rotating table through the telescopic assembly.

[0036] After adopting this technical solution, it should be noted that during the operation of the tracked vehicle, due to factors such as the fluctuation of the suspension height and the unevenness of the road surface, the tension of the track will also change dynamically. However, an overly loose track will experience jumping vibration or derailment during movement, while an overly tight track will increase the friction between the tensioning wheel and the track, resulting in energy loss and wear. By controlling the telescopic amount of the telescopic component, the longitudinal movement of the tensioning wheel can be achieved, and the tightness of the track can be adjusted while keeping the track height constant. By controlling the rotation angle of the rotating platform, the vertical movement of the tensioning wheel can be achieved to change the height of the track and make it adapt to various road conditions. Through the cooperation of the telescopic component and the rotating platform, the tension of the track can be adjusted;

[0037] Secondly, when the tracked vehicle body passes through an obstacle, the track will be impacted along the movement direction of the track. If this impact is too large, it may cause impact or even damage to the track, vehicle body, or frame structure. Therefore, when the track bears the impact, the telescopic component will also play an energy absorption role, reducing the impact on the overall structure and improving the stability of the vehicle body.

[0038] Furthermore, connection seats are provided at both ends of the upper surface of the upper support plate, and the rotating platform is connected to the connection seats.

[0039] Furthermore, a groove is provided on the tensioning wheel, and the groove meshes with the tooth track on the track.

[0040] After adopting this technical solution, it should be noted that a plurality of grooves are evenly distributed along the circumference on the tensioning wheel, and the arc length between adjacent two grooves is the same as the distance between adjacent two limit teeth, so that each limit tooth can mesh with the groove to achieve the stable rotation of the track.

[0041] The present utility model preferably relates to a magnetically levitated tracked vehicle driven by a linear motor. Two of the tensioning wheels are respectively connected to both ends of each track, and the tensioning wheels on both sides of the track respectively mesh with two tooth tracks to improve the load-bearing capacity and stability of the vehicle body.

[0042] The present utility model preferably relates to a magnetically levitated tracked vehicle driven by a linear motor, and the magnetic track adopts the shape of an F rail.

[0043] The present utility model has the following advantages and beneficial effects:

[0044] 1. The present utility model combines magnetic levitation and a linear electric drive system. In the vertical levitation, the static levitation of the vehicle body can be achieved without an initial speed. In addition, the non-contact characteristic of magnetic levitation significantly improves problems such as large vibration amplitude and high vibration frequency of the vehicle body in the stable levitation state, effectively improving the running quality and riding comfort of the tracked vehicle. After the primary winding of the linear electric drive system is energized, it interacts with the secondary iron sheet to drive the vehicle forward.

[0045] 2. The utility model sets the vehicle frame as a T-shaped vehicle frame, and reasonably arranges the positions of the vehicle body and the load wheels relative to the vehicle frame, making full use of the space, so that the entire chassis structure is compact, the chassis volume is reduced, the mass is reduced, and it is more energy-efficient.

[0046] 3. The utility model embeds the secondary magnetic sheet inside the crawler. On the one hand, the stability of the secondary magnetic sheet is enhanced, making the secondary magnetic sheet not easily interfered with and damaged by the external environment. On the other hand, the stability of the secondary magnetic sheet enables the primary winding to achieve good interaction with it in any environment or road condition, ensuring the stable movement of the crawler.

[0047] 4. The utility model sets a tensioning support system. By controlling the telescopic amount of the telescopic component, the longitudinal movement of the tensioning wheel can be realized, and the tightness of the crawler can be adjusted while keeping the height of the crawler constant. By controlling the rotation angle of the rotating platform, the vertical movement of the tensioning wheel can be realized to change the height of the crawler, making it adapt to various road conditions.
