Description

Technical Field

[0003] There are corresponding improvements in the prior art to address the above problems. For example, a Chinese patent application with a publication date of 2013-03-20 and a publication number of CN102980786A discloses a vehicle-mounted mobile fully automatic coal sampling and preparation machine and a coal sampling and preparation method. The sampling and preparation machine comprises a vehicle chassis (1), a subframe, hydraulic legs (4, 8), a sampling device (7), a sample preparation device (3), a sample collection device, a sample discard box (2), a hydraulic oil tank (5), a cooler (6) and an electric control cabinet (9). The subframe is arranged on the vehicle chassis (1), and the other components are installed on the subframe. The coal sampling and preparation machine integrates sampling, sample delivery, sample preparation and sample discarding, can provide accurate and reliable sample preparation for coal quality analysis and testing, and has the advantages of high work efficiency, wide application range, high degree of automation, safe and convenient operation, etc. The shortcomings of this solution are: due to layout limitations, it only has a single sample preparation device, and the sample quality is poor; at the same time, the sampling device is directly moved above the sample preparation device to transfer the sample, which can easily cause the sample to fall on other equipment, resulting in reduced reliability of other equipment, and then reduced reliability of coal sampling and preparation operations. Summary of the invention

[0004] The purpose of this application is to solve the problems of poor coal sample quality and low reliability of sampling and processing operations in the prior art. Therefore, this application provides a sampling and processing system for a coal sample sampling and processing detection vehicle, which realizes secondary preparation of samples, improves the quality of coal samples, and improves the reliability of sampling and processing operations by matching the material blocking cover with the sampling arm, and further improves the quality of coal samples.

[0062] See also Figure 1-3 , Figure 1 This is a schematic diagram of the structure of the sample collection and preparation system in Example 1 of the present application in use; Figure 2 for Figure 1 A schematic diagram of a top view structure, wherein the first L-shaped cover plate 207 and the second L-shaped cover plate 208 are omitted; Figure 3 for Figure 1 Schematic diagram of the structure of the bottom of the vehicle.

[0063] The embodiment of the present application provides a sampling system for a coal sampling and testing vehicle, including a vehicle body 200, in which a control unit, and a sampling unit and a power unit both connected to the control unit are arranged.

[0064] It can be understood that the control unit controls the operation of the collection and production unit, and the power unit provides power to the control unit and the collection and production unit.

[0065] In one embodiment, the sampling unit includes a mechanical arm 300 and a primary sample preparation device 400 and a secondary sample preparation device 600 respectively arranged on both sides of the mechanical arm 300. The primary sample preparation device 400 and the secondary sample preparation device 600 realize secondary preparation of the sample, which meets the requirements of the national standard "sample preparation after merging sub-samples" and improves the quality of the coal sample.

[0066] In addition, the first-level sample preparation device 400 and the second-level sample preparation device 600 are respectively arranged on both sides of the robot arm 300, which facilitates the operation of the robot arm 300 and improves the weight balance on both sides of the robot arm 300, thereby improving the stability and safety of the car body 200 during movement, thereby making the sampling system suitable for movement and improving the flexibility of coal sampling.

[0067] In one embodiment, a sampling arm 310 is detachably provided at the end of the mechanical arm 300 , and the mechanical arm 300 is used to drive the sampling arm 310 to extend into the coal for sampling, thereby improving the automation of coal sampling.

[0068] Furthermore, the sampling arm 310 and the end of the mechanical arm 300 are detachably connected, so that the end of the mechanical arm 300 can be replaced with different sampling arms 310 and different execution end mechanisms according to the requirements of coal sampling, thereby realizing different operations.

[0069] In one embodiment, the sampling arm 310 includes a barrel 311 and a sampling mechanism disposed in the barrel 311. The barrel 311 is provided with a plurality of windows 312 that penetrate the interior thereof along its height direction, and the sample collected by the sampling mechanism can overflow the sampling arm 310 through the window 312. The window 312 can be covered with a closing plate, so that the sampling amount can be controlled by closing the windows 312 at different heights, and the operation is convenient.

[0070] It is understandable that the sampling mechanism in the sampling arm 310 may be a conventional sampling mechanism in the art such as a spiral impeller.

[0071] In one embodiment, the robot arm 300 is a six-axis robot arm 300, which can improve the degree of freedom of operation and realize more operations.

[0072] In one embodiment, the primary sample preparation device 400 includes a crusher 420 and a reducer 430. The crusher 420 is used to crush the sample. The reducer 430 is disposed below the crusher 420 and is connected to the crusher 420 and is used to prepare a primary reduced sample.

[0073] In one embodiment, the first-level sampling device 400 also includes a material blocking cover 410, which is arranged on the crusher 420 and is adapted to the sampling arm 310. The material blocking cover 410 is used to guide the sample collected by the sampling arm 310 into the crusher 420, so as to prevent the sample collected by the sampling arm 310 from falling and affecting the reliability of other devices, thereby improving the reliability of the sampling operation and ensuring that all the sampled samples fall into the crusher 420, thereby avoiding the loss of samples during docking, thereby improving the quality of the coal sample.

[0074] In one embodiment, the material blocking cover 410 includes a material blocking portion 411 and a flow guiding portion 412 .

[0075] In one embodiment, the material blocking portion 411 is vertically arranged, and both ends in the height direction are connected, and it is a semi-enclosed structure in the circumferential direction. The robotic arm 300 can drive the sampling arm 310 at its end to embed into the material blocking portion 411, and make the window 312 of the sampling arm 310 blocked by the inner wall of the material blocking portion 411, so that when the sampling arm 310 outputs the sample, the sample is prevented from falling from the window 312. Even if there is a fallen sample, it can still fall into the crusher 420 through the cooperation of the material blocking portion 411 and the guide portion 412, thereby avoiding the loss of the sample during docking, thereby improving the quality of the coal sample.

[0076] At the same time, the through end and the semi-enclosed structure of the material blocking portion 411 improve the compatibility of the material blocking portion 411 with various types of sampling arms 310 , thereby improving the versatility of the material blocking cover 410 .

[0077] Preferably, the material blocking portion 411 circumferentially includes a flat plate and curved plates extending from both sides of the flat plate, an opening for the sampling arm 310 to enter is formed between the two curved plates, and the two curved plates are relatively bent to form an embracing shape, thereby expanding the internal space of the material blocking portion 411, making it easier for samples to fall from between the sampling arm 310 and the material blocking portion 411, and at the same time adapting to the funnel-shaped guide portion 412 arranged therebelow.

[0078] In one embodiment, the guide portion 412 is located at the end of the material blocking portion 411 and is funnel-shaped, thereby guiding the sample and avoiding sample loss during docking, thereby improving the quality of the coal sample.

[0079] In one embodiment, the end of the robot arm 300 may be detachably provided with a first actuator 320 or a second actuator 330 .

[0080] In one embodiment, the secondary sample preparation device 600 includes a reduction table 610, and the robotic arm 300 is used to transfer multiple primary reduction samples to the reduction table 610 through the first actuator 320, and to mix the multiple primary reduction samples in the reduction table 610 through the second actuator 330 to prepare secondary reduction samples, so as to further improve the uniformity of the samples, improve the detection accuracy, and realize automated operation, thereby improving the safety and efficiency of sampling.

[0081] In one embodiment, the secondary sample preparation device 600 further includes a conveyor belt and a flattening mechanism. The conveyor belt passes through the exit of the reduction table 610 and the flattening mechanism in sequence along its conveying direction. The flattening mechanism is used to flatten the sample on the conveyor belt, so that the final test sample is in a flattened state, which is conducive to improving the accuracy of the test. Preferably, the conveyor belt passes through the test port, and the end of the conveyor belt is a discard port, so that flattening, testing, and discarding share a conveyor belt, which has a compact structure.

[0082] This setting is particularly suitable for testing samples using visual coal quality detectors, such as X-ray fluorescence coal quality detectors, which can greatly improve detection accuracy.

[0083] In one embodiment, a sample collecting box 700 is provided below the carriage body 200 corresponding to the primary sample preparing device 400. The sample collecting box 700 is connected to the primary sample preparing device 400 to collect the once-shrink samples, and then transfer them to the secondary sample preparing device 600, thereby improving the efficiency of coal sampling.

[0084] In one embodiment, a rotary conveyor belt 710 is disposed in the sample collection box 700, and a plurality of supporting plates are disposed on the rotary conveyor belt 710. The supporting plates are used to place sample barrels 720, and the plurality of sample barrels 720 are driven by the rotary conveyor belt 710 to move one by one and connect with the primary sample preparation device 400, so as to realize the differentiated collection of the first-stage reduction samples collected from different positions, thereby facilitating the centralized completion of sampling work in different areas, and then replacing the end mechanism of the robot arm 300 to perform secondary reduction sample preparation, thereby improving the sampling efficiency.

[0085] The rotary conveyor belt 710 may be a conveyor chain, and the sample barrel 720 may be detachably connected to the carrying plate to improve its stability in moving with the rotary conveyor belt 710 .

[0086] In one embodiment, the carriage body 200 is provided with a first area 210 and a second area 220 isolated from each other along its width direction, so that the first area 210 and the second area 220 have a longer space, thereby facilitating the side-by-side arrangement of multiple devices and facilitating maintenance.

[0087] Furthermore, the first area 210 and the second area 220 are respectively located at two sides of the vehicle body 200 , so that when the vehicle body 200 is disposed on a vehicle, it is convenient for the vehicle to be driven to a designated position for operation.

[0088] In one embodiment, the first zone 210 is provided with a control zone 221 and a power zone 222 that are isolated from each other along the length direction of the vehicle body 200 .

[0089] The control unit is disposed in the control area 221 , and the control unit may include but is not limited to a power distribution cabinet 201 , a PLC control cabinet 202 , a robotic arm control cabinet 203 , and a quality inspection control cabinet 204 .

[0090] The power unit is disposed in the power area 222 , and the power unit includes a generator set 205 and a robot arm power system 206 .

[0091] At this time, the manipulator control cabinet 203 is connected to the manipulator 300, the generator set 205 is used for power supply, the manipulator power system 206 is connected to the manipulator 300 and is used to control the movement of the manipulator 300, and the PLC control cabinet 202 is used to control the entire coal sampling process. Preferably, the manipulator power system 206 is an air compression system.

[0092] In one embodiment, the mining and production unit is arranged in the second area 220, so that the mining and production operation area is isolated from the control area 221 and the power area 222, reducing the intrusion of coal dust and the like into the control area 221 and the power area 222, and realizing dust protection for the control unit and the power unit.

[0093] This method reduces the independent dustproof performance requirements for each device by isolating the first zone 210 and the second zone 220 and isolating the control zone 221 and the power zone 222 of the first zone 210, thereby reducing costs. In addition, by allocating the first zone 210 and the second zone 220 and installing each device in different zones, the convenience of sampling, testing and maintenance is improved; by arranging each device, the stability and safety of the carriage body 200 are improved.

[0094] In one embodiment, the primary sample preparation device 400 and the secondary sample preparation device 600 are arranged on both sides of the robot arm 300 along the length direction of the second zone 220, so that the robot arm 300 can perform sampling and the robot arm 300 and the primary sample preparation device 400, as well as the robot arm 300 and the secondary sample preparation device 600 can cooperate in a limited space. In addition, the weight distribution of the second zone 220 is more reasonable, thereby improving the stability and safety of the vehicle body 200 when moving.

[0095] In one embodiment, the generator set 205 and the robotic arm 300 are correspondingly arranged in the width direction of the vehicle body 200, further balancing the weight of the first area 210 and the second area 220, that is, improving the left-right balance of the vehicle body 200, thereby improving the stability and safety of the movement of the vehicle body 200 when moving, such as when being mounted on a vehicle.

[0096] It should be noted that the power units and control units arranged in the first area 210, such as the generator set 205, the robot power system 206, and various control units, are relatively regular in appearance, and have high integration and compactness; the sampling and processing units arranged in the second area 220, such as the robot 300, the primary sample preparation device 400, the secondary sample preparation device 600, etc., are different in appearance, and the robot 300 requires a certain amount of space for movement; and the weight of the generator set 205 is much greater than that of other devices.

[0097] Therefore, in one embodiment, the width of the first area 210 is smaller than the width of the second area 220, that is, the area of ​​the first area 210 is smaller than the area of ​​the second area 220, which is convenient for the installation of various devices; and the area of ​​the second area 220 is relatively large, providing a relatively large activity space for the robot arm 300, which is convenient for the operation of the robot arm 300. At the same time, when the center of gravity of the first area 210 and the second area 220 are both at their centers, the force arm of the first area 210 is smaller than the force arm of the second area 220, and the weight of the first area 210 is much greater than the weight of the second area 220, so that the left and right sides of the vehicle body 200 are balanced, so that when the vehicle body 200 moves, such as when it is mounted on a vehicle, the moving stability and safety are improved.

[0098] See also Figure 4-5 , Figure 4It is a schematic diagram of the structure of the waste material recovery device and the sample collection box 700 in Example 1 of the present application; Figure 5 It is a partially enlarged structural schematic diagram of the waste material recovery device in the embodiment of the present application.

[0099] In one embodiment, a waste material collection box 800 is provided below the vehicle body 200 corresponding to the secondary sample preparation device 600, and the waste material collection box 800 is connected with the primary sample preparation device 400 and the secondary sample preparation device 600 via a transmission device 810, so as to realize real-time collection of waste materials, avoid direct discharge of waste materials, pollute the environment, or even mix into the area to be sampled, affecting the detection accuracy.

[0100] At the same time, the waste material collection box 800 is heavier, and the secondary sample preparation device 600 is lighter than the primary sample preparation device 400. By setting the waste material collection box 800 below the secondary sample preparation device 600, the front and rear balance of the car body 200 can be improved, and the waste material collection box 800 is basically located on the diagonal line of the power unit (mainly the generator set 205), which can improve the left and right balance of the car body 200, so that when the car body 200 moves, such as when it is mounted on a vehicle, the movement stability and safety are improved.

[0101] In this embodiment, the waste material collection box 800 is connected to the primary sample preparation device 400 and the secondary sample preparation device 600 through a transmission device 810, such as a conveyor belt. The transmission device 810 transmits the waste materials generated by the primary sample preparation device 400 and the secondary sample preparation device 600 to the waste material collection box 800. That is, the coal sampling and testing vehicle also includes a waste material recovery device, and the waste material recovery device includes a waste material collection box 800 and a transmission device 810.

[0102] In one embodiment, the shrinking machine 430 of the primary sample preparation device 400 is provided with two outlets, and one outlet faces the transmission device 810 to convey the shrinking waste to the waste collection box 800, and the other outlet faces the sample collection box 700 to collect the shrinking samples. For example, the two outlets of the shrinking machine 430 are respectively provided with discharge guide cylinders, one discharge guide cylinder faces the transmission device 810, and the other discharge guide cylinder faces the sample collection box 700.

[0103] In one embodiment, the waste collection box 800 has a first inlet and a second inlet. The first inlet receives waste from the primary sample preparation device 400 through a transmission device 810, and the second inlet is used to receive other waste materials, including but not limited to waste from the secondary sample preparation device 600.

[0104] In one embodiment, the first inlet is in the shape of an elongated strip, that is, the coal falls into the waste collection box 800 at multiple locations, and can be concentrated in more than one location of the waste collection box 800, thereby improving the space utilization of the waste collection box 800, eliminating the need for frequent dumping, and thus improving the convenience of use of the device and the actual use effect. Furthermore, the first inlet extends along the length direction of the waste collection box 800, that is, the coal can cover the space in the waste collection box 800 to the greatest extent.

[0105] At this time, the transmission device 810 includes a limit frame 811 and a transmission line group arranged in the limit frame 811. The bottom of the limit frame 811 has a closed part and an outlet part, the closed part is used to prevent the coal in the limit frame 811 from falling, and the outlet part is long and arranged corresponding to the first entrance. The transmission line group is transmitted along the length direction of the abandoned material collection box 800, and the bottom is hollowed out and covers the first entrance. The transmission line group is connected to the driving member and reciprocates under the drive of the driving member, so that the coal gradually falls from the outlet to the first entrance under the drive of the transmission line group, so that the coal can be gradually accumulated in various positions of the abandoned material collection box 800 along the transmission direction when the transmission line group keeps the working state unchanged, thereby improving the space utilization rate of the abandoned material collection box 800, reducing the dumping frequency of the abandoned material collection box 800, and thus improving the convenience of use of the device, improving the actual use effect, and at the same time, the operation control of the transmission line group is simple.

[0106] During use, the coal is first accumulated at the front end of the first entrance. As the amount of coal increases to be basically flush with the bottom of the transmission line group, the coal transported subsequently cannot fall at this position, but falls as the transmission line group moves to a farther distance, thereby achieving distributed accumulation at various positions of the waste collection box 800, thereby improving the space utilization rate of the waste collection box 800.

[0107] In one embodiment, the transmission line group includes a transmission chain 812 and a plurality of push plates 813 arranged at intervals on the sides of the transmission chain 812, the transmission chain 812 is connected to the driving member, the plurality of push plates 813 are adapted to the limit frame 811 and form a plurality of push spaces, the plurality of push spaces move under the drive of the transmission chain 812, and push the coal to the first entrance. The transmission chain 812 is preferably a roller chain.

[0108] It should be noted that the coal is in granular form and is easily jammed due to squeezing when being pushed forward through the transmission line assembly, causing it to be unable to fall immediately.

[0109] This method forms a larger pushing space through the push plate 813 and the limit frame 811, which can reduce the risk of coal getting stuck in the transportation line group during transportation and improve transportation reliability; and the longer discarding route formed by the longer first entrance and the longer exit can make the stuck coal pile loosen and fall due to vibration during the movement of the transmission equipment 810, so as to achieve complete discarding; even if it is stuck and cannot be removed, only the independent unit of the transmission chain 812 and the push plate 813 at the corresponding position can be disassembled and replaced, which reduces maintenance costs.

[0110] In one embodiment, the second inlet is located at a position of the waste material collection box 800 away from the outlet of the reduction table 610, so as to facilitate the setting of the conveyor belt of the secondary sample preparation device 600. At the same time, the transmission equipment 810 of the waste material recovery device and the conveyor belt of the secondary sample preparation device 600 can also be arranged in parallel above the waste material collection box 800, thereby improving space utilization.

[0111] In one embodiment, the sampling unit also includes a rack 900, which is used to accommodate the sampling arm 310, the first actuator 320 and the second actuator 330, so that the robotic arm 300 can replace the sampling arm 310, the first actuator 320 and the second actuator 330 in time during the sampling process, thereby improving the sampling efficiency.

[0112] Preferably, the rack 900 is arranged at one end of the primary sample preparation device 400 away from the robot arm 300. It is within the range of motion of the robot arm 300, allowing the end mechanism to be replaced while avoiding affecting the regular operation of the robot arm 300, further ensuring the sampling and testing efficiency.

[0113] In one embodiment, the rack 900 is provided with a plurality of vertical accommodating spaces, and a card interface 910 for clamping the sampling arm 310 or the first actuator 320 or the second actuator 330 is provided at the top of the vertical accommodating space, so that the sampling arm 310, the first actuator 320 and the second actuator 330 can be stored in a vertical state in the rack 900, and the sampling arm 310, the first actuator 320 and the second actuator 330 in a vertical state can be easily installed or disassembled automatically by the robot arm 300.

[0114] Since the rack 900 is arranged in the second zone 220 and directly faces the sampling zone, coal is easy to fall from above to the sampling arm 310, the first actuator 320 and the second actuator 330 in the rack 900, causing damage or affecting the detection accuracy. Therefore, preferably, the top of the card interface 910 is covered with a removable top cover.

[0115] In one embodiment, the sampling unit also includes a password packaging table 620, which is disposed at one end of the reduction table 610 close to the robotic arm 300, and a closable sample barrel 720 is disposed on the password packaging table 620. The closable sample barrel 720 is used to store part of the samples in the reduction table 610 to preserve the samples.

[0116] See also Figure 8-9 , Figure 8 This is a schematic diagram of the structure of the first actuator 320 in the embodiment of the present application; Fig. 9 Schematic diagram of the structure of the second actuator 330 in the embodiment of the present application.

[0117] In one embodiment, the robot arm 300 transfers the sample barrel 720 between the sample collection box 700 and the reduction table 610 through the first actuator 320, and transfers the sample in the sample barrel 720 to the reduction table 610, and the robot arm 300 closes the closable sample barrel 720 through the first actuator 320. For example, the first actuator 320 includes a clamp 331 for grabbing the sample barrel 720, and a suction cup 322 for taking the cover 630 of the sample barrel 720, and the suction cup 322 can be set on the arm of the clamp 331, or any position that can take into account the operation of the clamp 331 and the operation of the suction cup 322.

[0118] The robot arm 300 extends into the reduction platform 610 through the second actuator 330 and stirs and mixes the sample in the reduction platform 610, and grabs part of the sample and puts it into the closable sample barrel 720. For example, the second actuator 330 includes a stirring member for stirring the sample and a grabbing member for grabbing the sample.

[0119] In a specific embodiment, the stirring member of the second actuator 330 is a stirring plate 331, and the stirring member is driven by the mechanical arm to stir. The grasping member includes a receiving tube 332, a push-pull rod 333, and a transmission connecting rod group 334. The push-pull rod 333 drives the receiving tube 332 away from or close to the stirring plate 331 through the transmission connecting rod group 334 to realize the opening and closing of the receiving tube 332 to receive and seal the sample, and is driven by the mechanical arm to move to the top of the sample barrel 720 on the password packaging table 620.

[0120] In one embodiment, the vehicle body 200 includes a bottom plate, two side plates arranged along its length direction, and a first partition plate arranged on the bottom plate. The two side plates and the first partition plate separate the vehicle body 200 into a first area 210 and a second area 220. The structure is simple and easy to assemble, and it is convenient to set the first L-shaped cover plate 207 and the second L-shaped cover plate 208 by hinged connection with the top of the first partition plate.

[0121] The top of the first partition is rotatably connected with the first L-shaped cover plate 207 and the second L-shaped cover plate 208, and the first L-shaped cover plate 207 is used to cover the first area 210, and the second L-shaped cover plate 208 is used to cover the second area 220, so that when the first L-shaped cover plate 207 and the second L-shaped cover plate 208 are opened, the front of the first area 210 and the second area 220 can be unobstructed, and the top space of the first area 210 and the second area 220 can be greatly expanded, thereby facilitating operation and maintenance.

[0122] Embodiment 2:

[0123] See also Figure 6-7 , Figure 6 This is a schematic diagram of the state of sampling and testing of coal loaded in a train carriage according to Example 2 of the present application; Figure 7 This is a schematic diagram of the status of coal pile sampling and detection in Example 2 of the present application.

[0124] On the basis of Example 1, this embodiment provides a coal sampling and testing vehicle, including a cab frame assembly 100 and the sampling system of Example 1, and the vehicle body 200 of the sampling system is arranged on the frame of the cab frame assembly 100, so as to realize the on-vehicle movement of the sampling system, and can move freely in a variety of sampling environments, thereby improving the flexibility of coal sampling.

[0125] In one embodiment, the coal sampling and testing vehicle further includes a detection device 500, which is disposed in the carriage 200 of the sampling and testing system, thereby integrating the sampling and testing system and the detection device 500 on the same vehicle, which not only reduces the area occupied by coal sampling and testing, but also greatly shortens the time from sampling and testing to sample testing, thereby improving the sampling and testing efficiency and the accuracy of sample moisture detection. Preferably, the detection device 500 is disposed between the mechanical arm 300 and the secondary sampling and testing device.

[0126] In one embodiment, the cab frame assembly 100 includes a vehicle power mechanism, and the vehicle power mechanism is disposed below the cab of the cab frame assembly 100, thereby facilitating the overall balance setting of the vehicle and improving the stability and safety of the vehicle.

[0127] In one embodiment, a vehicle energy storage device 110 is disposed along the width direction of the vehicle body 200 and corresponding to the waste material collection box 800 .

[0128] The vehicle energy storage device 110 is a fuel tank for a fuel vehicle and a battery pack for an electric vehicle, and is usually heavy. Coal sample preparation usually adopts a reduction method, resulting in more waste materials, and thus the weight of the waste material collection box 800 is also large. By arranging the waste material collection box 800 and the vehicle energy storage device 110 in the width direction of the vehicle body 200, the left-right balance of the vehicle is improved, thereby improving the stability and safety of the vehicle.

[0129] In one embodiment, the generator set 205 and the mechanical arm 300 are respectively located above the two rear wheels 120 of the cab frame assembly 100, that is, the generator set 205 and the mechanical arm 300 with the heaviest weight in the vehicle body 200 are respectively located above the rear wheels 120, thereby improving the stability and safety of the vehicle.

[0130] In one embodiment, the sample collection box 700 and the waste material collection box 800 are respectively located on both sides of the corresponding rear wheels 120 of the cab frame assembly 100, which is easy to install, improves the balance of the vehicle, and further improves the stability and safety of the vehicle.
