A motorcycle wheel hub and tire installation structure based on laser scanning

Abstract

The present invention provides a motorcycle wheel hub and tire mounting structure based on laser scanning, comprising a chassis body, wherein the upper end of the chassis body is provided with a rotating chassis capable of automatically rotating, and the tire bottom support assembly and the tire top support assembly are both transmitted in cooperation with the rotation of the rotating chassis. When the rotating chassis rotates to a rearward horizontal position, the transmission gear can be driven to enter a position meshing with the incomplete fixed gear, so that when the rotating chassis rotates, the bottom support blocks clamping the tire can synchronously move away from each other, and the passive inclined block can also drive the top support block to move away from the bottom support block when the bottom support block moves to a position tangent to the inclined surface of the fixed inclined block, and at the same time cooperate with the nylon pushing block to push the auxiliary clamping column in the elastically rotated state, so that after the tire and the wheel hub are respectively placed in the mounting positions, as the rotating chassis rotates, the tire automatically falls toward the wheel hub and is released. In conjunction with the use of the laser scanning module, the pressing assembly component can be used to accurately and safely press the tire and the wheel hub.

Description

Technical Field

[0001] The present invention relates to the technical field of motorcycle assembly, in particular to a motorcycle wheel hub and tire mounting structure based on laser scanning. Background Art

[0002] The assembly of motorcycle tires and wheels is a critical step in vehicle manufacturing, and its quality directly impacts vehicle safety, handling, comfort, and tire life. In vehicle manufacturing workshops, the traditional method of installing tires is to use a mechanical pressure device. The wheel hub is positioned in a certain position, the tire is then attached to the upper end of the hub, and the pressure device is manipulated using a lever to press the tire into the outer surface of the hub.

[0003] The pressure blocks used in the pressure device used in the above operation for pressing the tire are generally symmetrically distributed. After the tire is overlapped on the upper end of the wheel hub in an interlaced manner, the pressure device is rotated to visually find the appropriate force application position on the outside of the tire. After the two pressure blocks of the pressure device are symmetrically distributed on both sides of the interlaced center line of the tire and the wheel hub, the tire can be pressed in manually or mechanically. However, there are disadvantages of low operating efficiency and excessive human errors. Summary of the Invention

[0004] The purpose of the present invention is to provide a motorcycle wheel hub and tire mounting structure based on laser scanning. By utilizing the rotating action of the turntable and the coordinated transmission formed by the tire bottom support assembly and the tire top support assembly, the purpose of safely releasing the tire toward the top of the wheel hub can be achieved after the wheel hub and tire are clamped and the turntable is rotated to a horizontal position. This not only facilitates the placement of the wheel hub and tire after tilting the turntable forward, but also enables the automatic release of the tire during the rotation of the turntable to a water level safety position.

[0005] The objective of the present invention is achieved through such a technical solution, a motorcycle wheel hub tire mounting structure based on laser scanning, comprising a chassis, a turret assembly, a tire bottom support assembly, a tire top support assembly and an auxiliary clamping column component, wherein the turret assembly includes a turret, the tire bottom support assembly includes a corner seat and an incomplete fixed gear, the tire top support assembly includes a passive bevel block, and the auxiliary clamping column component includes an auxiliary clamping column;

[0006] The turret is rotated to the upper end of the frame of the bottom frame body, the corner seats are symmetrically slidably connected to the inner frame of the turret, the top of each group of corner seats is fixed with a bottom supporting block, the bottom end of the inner frame of the turret is laterally rotated with a passive screw, and the symmetrically distributed corner seats are all connected with the passive screw, the incomplete fixed gear is fixed to one side of the inner upper end of the bottom frame body, the bottom end of the inner frame of the turret is rotated with a transmission gear, the transmission gear is connected to one end of the passive screw, and when the turret is within a certain angle of rotation, the transmission gear is meshed with the incomplete fixed gear;

[0007] Each set of corner seats is also elastically slidably connected to a top supporting block in the direction of the bottom supporting block, the passive oblique block is fixed to one side of the top supporting block, and a pair of fixed oblique blocks are fixed to one side of the inner frame of the rotating frame;

[0008] The bottom end of the auxiliary clamping column is elastically screwed to the middle part of the outer side of the rotating frame, and a nylon pushing block is fixed to one side of the top end of the bottom frame body.

[0009] The use process of the technical solution of the present invention is as follows:

[0010] When the turntable is tilted forward and rotated to a certain position, the wheel hub can be inserted through its center hole and placed in the middle of the inner frame of the turntable;

[0011] When the rotating frame tilts forward and rotates to a certain position, the two sets of corner seats are also at their extreme positions close to each other, and the top supporting block is at its extreme position close to the bottom supporting block. After the wheel hub is installed, the tire can be clamped into the three-point support space formed by the top supporting blocks and bottom supporting blocks symmetrically distributed on both sides and the auxiliary clamping columns, and the placed tire and wheel hub are in a non-facing state;

[0012] When the turret tilts forward and rotates to the position where the wheel hub and tire are placed, the transmission gear is not engaged with the incomplete fixed gear. Only when the turret rotates backward to a certain angle does the transmission gear enter a state of meshing with the incomplete fixed gear.

[0013] After the tire and wheel hub are placed, the rotating frame is rotated in the backward direction so that the rotating frame gradually rotates to a horizontal position. During the process of the rotating frame rotating backward to the horizontal position, the transmission gear enters into a state of meshing with the incomplete fixed gear. At this time, as the rotating frame continues to rotate backward to the horizontal direction, it can drive the transmission gear in the free rotating state to form a coordinated transmission with the incomplete fixed gear in the fixed position, thereby driving the rotation of the passive lead screw. The coordinated transmission formed by the passive lead screw and the symmetrically distributed corner seats can drive the two groups of corner seats to move away from each other, thereby achieving the purpose of gradually releasing the tire.

[0014] When the two groups of corner seats move away from each other to a certain position, the passive inclined block on one side of the top supporting block enters into tangential cooperation with the inclined surface of the fixed inclined block. As the two groups of corner seats continue to move away from each other, the top supporting block is synchronously driven to overcome its own elastic force and move away from the bottom supporting block, gradually losing the tight state on the tire until both the bottom supporting block and the top supporting block are separated from the outside of the tire.

[0015] At the same time, and before the turret rotates backward to the horizontal position, while the bottom support block and the top support block are separating from the outside of the tire, the auxiliary clamping column will also contact the nylon push block, causing the auxiliary clamping column to gradually separate from the outside of the tire, causing the tire to fall to the top of the wheel hub due to its own gravity, and form a staggered state;

[0016] The turret is then rotated back to a horizontal position, which is convenient for installing the tire and wheel. The laser scanning device on the top of the chassis can scan the actual contact position of the tire with the wheel, which is convenient for guiding subsequent installation work.

[0017] After the tire and wheel hub are installed, tilt the rotating frame forward and remove the wheel hub and tire.

[0018] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0019] (1) The present invention is based on an automatically rotating turret, which can facilitate the safe placement of the front wheel hub and tire, and safely install the tire and wheel hub after the turret is rotated to a horizontal position;

[0020] (2) The present invention utilizes the bottom support block and the top support block with a certain height difference from the wheel hub after installation to form a clamping work for the tire to be installed, and cooperates with the auxiliary clamping column elastically screwed on the middle part of the outer side of the rotating frame to form a three-point stable support state for the tire; and after the rotating frame is rotated backward to a certain angle, not only the transmission formed by the transmission gear and the incomplete fixed gear can be used to drive the symmetrically distributed bottom support blocks to move away from each other, but also the inclined surface formed by the passive inclined block and the fixed inclined block is used to drive the top support block to move away from the bottom support block, so that when the rotating frame is rotated backward to a safe position, the top support block and the bottom support block can be separated from the outside of the tire, and under the action of the tire's own gravity, they can fall to a position staggered with the top end of the wheel hub. At this time, the free fall of the tire will not fall to a position outside the wheel hub;

[0021] (3) In order to achieve the free and smooth fall of the tire after the top support block and the bottom support block are separated from the outside of the tire, the present invention is also provided with an auxiliary clamping column and a nylon push block to form an elastic contact fit. The elastic rotation relay force formed by the auxiliary clamping column itself can not only cooperate with the top support block and the bottom support block to form a support for the tire to be installed, but also make the nylon push block contact with the auxiliary clamping column when the turntable rotates backward to a safe position, pushing the auxiliary clamping column away from the outside of the tire, so as to achieve the purpose of free and unobstructed fall of the tire.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0050] like Figures 1-16 As shown, a motorcycle wheel hub tire mounting structure based on laser scanning is shown. The rotating frame 203 in the rotating frame assembly 2 is screwed to the upper end of the frame of the bottom frame body 1, and the rotating frame 203 can automatically rotate within a certain angle range. The corner seats 303 are symmetrically slid in the inner frame of the rotating frame 203. The top of each group of corner seats 303 is fixed with a bottom support block 304. The bottom end of the inner frame of the rotating frame 203 is screwed with a passive screw 305 in the horizontal direction, and the symmetrically distributed corner seats 303 are all connected with the passive screw 305. When the turret 203 rotates, the two groups of corner seats 303 can be driven to move toward each other. The incomplete fixed gear 306 is fixed to one side of the inner upper end of the bottom frame body 1. The bottom end of the inner frame of the rotating frame 203 is rotated with a transmission gear 311. The transmission gear 311 is connected to one end of the passive lead screw 305. When the turret 203 is within a certain angle of rotation, the transmission gear 311 is engaged with the incomplete fixed gear 306, so that as the turret 203 rotates, the two groups of corner seats 303 can be opened and closed synchronously.

[0051] Each set of corner seats 303 is also elastically connected to a top supporting block 402 that slides toward the bottom supporting block 304. The passive inclined block 403 is fixed to one side of the top supporting block 402. A pair of fixed inclined blocks 404 are fixed to one side of the inner frame of the rotating frame 203. When the corner seats 303 move laterally to a certain position, the passive inclined blocks 403 can form an inclined surface tangent to the fixed inclined blocks 404, so that when the two sets of corner seats 303 move away from each other, the top supporting block 402 can move away from the bottom supporting block 304 synchronously.

[0052] The bottom end of the auxiliary clamping column 706 is elastically screwed to the middle part of the outer side of the rotating frame 203. A nylon push block 708 is fixed to one side of the top of the bottom frame body 1. When the rotating frame 203 is rotated backward to a certain position, the top outer surface of the auxiliary clamping column 706 can contact and abut against the nylon push block 708.

[0053] Here's how it works:

[0054] This device is used for installing motorcycle tires and wheels;

[0055] When the rotating frame 203 is tilted and rotated to a certain position, it can form a state convenient for the installation of the wheel hub and the tire. The wheel hub can be inserted into the middle of the inner frame of the rotating frame 203 through its center hole.

[0056] When the rotating frame 203 tilts forward and rotates to a certain position, the two sets of corner seats 303 are also at their extreme positions close to each other, and the top supporting block 402 is at its extreme position close to the bottom supporting block 304. After the wheel hub is installed, the tire can be clamped into the three-point support space formed by the top supporting blocks 402 and the bottom supporting blocks 304 symmetrically distributed on both sides and the auxiliary clamping column 706, and the tire clamped between the top supporting block 402 and the bottom supporting block 304 is in a compressed state.

[0057] Furthermore, the top support block 402, the bottom support block 304, and the auxiliary clamping post 706 will not interfere with the placement of the wheel hub before the tire;

[0058] The placed tires and wheels are not aligned, so that they can overlap on top of the wheels when released.

[0059] When the turret 203 tilts forward and rotates to a position where the wheel hub and tire are placed, the transmission gear 311 is not engaged with the incomplete fixed gear 306. Only after the turret 203 rotates backward to a certain angle does the transmission gear 311 engage with the incomplete fixed gear 306, so as to transport the tire to a safe position.

[0060] After the tire and wheel hub are placed, the rotating frame 203 is rotated in the backward direction so that the rotating frame 203 gradually rotates to a horizontal position. During the process of the rotating frame 203 rotating backward to the horizontal position, the transmission gear 311 enters into a state of meshing with the incomplete fixed gear 306. At this time, as the rotating frame 203 continues to rotate backward to the horizontal direction, it can drive the transmission gear 311 in the free rotating state to form a coordinated transmission with the incomplete fixed gear 306 in the fixed position, thereby driving the rotation of the passive screw 305. The coordinated transmission formed by the passive screw 305 and the symmetrically distributed corner seats 303 can drive the two groups of corner seats 303 to move away from each other, thereby achieving the purpose of gradually releasing the tire.

[0061] When the two groups of corner seats 303 move away from each other to a certain position, the passive inclined block 403 on one side of the top supporting block 402 enters into tangential cooperation with the inclined surface of the fixed inclined block 404. As the two groups of corner seats 303 continue to move away from each other, the top supporting block 402 is synchronously driven to overcome its own elastic force and move away from the bottom supporting block 304, gradually losing the tight state on the tire until both the bottom supporting block 304 and the top supporting block 402 are separated from the outside of the tire.

[0062] Simultaneously, and before the rotating frame 203 rotates backward to the horizontal position, while the bottom supporting block 304 and the top supporting block 402 are being separated from the outside of the tire, the auxiliary clamping column 706 also contacts the nylon pushing block 708, causing the auxiliary clamping column 706 to gradually separate from the outside of the tire, causing the tire to fall to the top of the wheel hub due to its own gravity, and form a mutually staggered state;

[0063] Then, the rotating frame 203 is rotated to a horizontal position by continuing to tilt back. At this time, a position is formed that is convenient for installing the tire and wheel hub. The laser scanning device on the top of the bottom frame body 1 can scan the actual contact position of the tire with respect to the wheel hub, which is convenient for guiding the subsequent installation work.

[0064] After the tire and wheel hub are installed, the rotating frame 203 is tilted forward to remove the wheel hub and tire. There is a certain height difference between the bottom supporting block 304 and the top supporting block 402 and related mechanisms used to clamp the tire and the installation position of the wheel hub, which will not interfere with the removal of the wheel hub and tire after installation.

[0065] The specific structure of the rotating frame assembly 2 is as follows: Figure 2 and Figure 3 As shown, the main rotating seat 201 is symmetrically fixedly installed on both sides of the upper end of the frame body 1, and the cylinder fixed rotating seat 202 is symmetrically fixedly installed on both sides of the lower end of the frame body 1;

[0066] Main rotating shafts 204 are laterally fixed on both sides of the bottom end of the inner frame of the rotating frame 203. The main rotating shafts 204 on the same side are rotatably connected to the main rotating base 201. The outer end of each set of main rotating shafts 204 is fixed to an external connecting base 205. The movable rotating shaft 206 is laterally fixed to the other side of the outer end of the external connecting base 205. The bottom end of the main body of the tilting electric cylinder 207 is rotatably connected to the cylinder fixed rotating base 202. The telescopic rod of the tilting electric cylinder 207 is rotatably connected to the movable rotating shaft 206.

[0067] By synchronously activating the two sets of tilting electric cylinders 207, the movement of the telescopic rods of the tilting electric cylinders 207, and the coordinated transmission formed by the telescopic rods of the tilting electric cylinders 207 and the movable rotating shaft 206, the external connecting base 205, the main rotating shaft 204 and the rotating frame 203 can be driven to rotate with the main rotating base 201 as the reference, thereby achieving the purpose of tilting the rotating frame 203 forward and backward.

[0068] A hub mounting seat 208 is fixedly mounted on the middle portion of the top of the inner frame of the rotating frame 203. When the hub is installed, the hub mounting seat 208 can be inserted into the center hole of the hub.

[0069] During the installation process of the tire and the wheel hub, the wheel hub is allowed to rotate based on the mounting seat 208, which will not cause adverse effects on the process of pressing the tire into the wheel hub.

[0070] The specific structure of the tire bottom support assembly 3 and the tire top support assembly 4 is as follows Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the slide grooves 301 are symmetrically opened in the inner frame body of the rotating frame 203, the inner slider 302 is fixedly connected to the bottom end of the corner seat 303, and the inner slider 302 on the same side is slidably connected in the slide groove 301;

[0071] Both sides of the bottom end of the inner frame of the rotating frame 203 are fixedly connected to the screw rotating seats 307. The two ends of the passive screw 305 are rotatably connected to different screw rotating seats 307. The bottom end of each group of inner sliders 302 is fixedly installed with a screw slider 308, which is in cooperation with the passive screw 305.

[0072] By setting the passive lead screw 305 part that cooperates with the two sets of lead screw sliders 308 to rotate left or right, a state in which a single passive lead screw 305 drives the two sets of lead screw sliders 308 to move toward each other can be formed. This is a prior art and will not be described in detail here.

[0073] A transmission shaft 310 is laterally fixed to one side of the bottom end of the inner frame of the rotating frame 203. A transmission gear 311 is rotatably connected to the transmission shaft 310. A lead screw gear 309 is fixed to one end of the passive lead screw 305. The lead screw gear 309 is meshed with the transmission gear 311.

[0074] After the transmission gear 311 enters the position of cooperating with the incomplete fixed gear 306, the rotation of the rotating frame 203 can drive the transmission gear 311 and the screw gear 309 to form a cooperative transmission, so that the rotation of the rotating frame 203 drives the passive screw 305 to rotate synchronously. By utilizing the cooperative transmission formed by the rotation of the passive screw 305 and the screw slider 308, the two sets of symmetrically distributed corner seats 303 can be driven to move toward each other.

[0075] A pair of sliding posts 405 are fixedly connected between the passive inclined block 403 and the slide 401 on the same side. The sliding posts 405 are slidably connected to the main body of the corner seat 303. The supporting block 402 is fixedly connected to the bottom end of the slide 401. A compression spring 406 is sleeved and installed in each set of sliding posts 405. One end of the compression spring 406 is clamped and fixed to the passive inclined block 403, and the other end is clamped and fixed to the corner seat 303.

[0076] Under the action of the elastic force of the compression spring 406 on the passive inclined block 403 relative to the corner seat 303, the top supporting block 402 can be elastically close to the bottom supporting block 304, so that when there is no external force pushing the passive inclined block 403, the top supporting block 402 is in a position to clamp the outside of the tire after being combined with the bottom supporting block 304.

[0077] The specific structure of the auxiliary clamping column component 7 is as follows Figure 13、 Figure 14 and Figure 15 As shown, the elastic fixed rotating seat 701 is fixedly connected to the middle part of the outer side of the rotating frame 203, the elastic rotating seat 702 is rotatably connected to the elastic fixed rotating seat 701, and a clamping seat 703 is fixed to the bottom end of the outer side of the frame of the rotating frame 203. An elastic connecting piece 704 is clamped and installed between the clamping seat 703 and the elastic rotating seat 702;

[0078] A flat support 705 is fixed to the top of the elastic rotating seat 702, and an auxiliary clamping column 706 is installed and fixed to one side of the top of the flat support 705;

[0079] The elastic connecting piece 704 clamped between the clamping seat 703 and the elastic rotating seat 702 can generate a supporting elastic force for the rotation of the elastic rotating seat 702, so that when the auxiliary clamping column 706 is not pushed by an external force, the auxiliary clamping column 706 is in a position to support the outer side of the tire;

[0080] One end of the top arm 707 is fixed to the middle of the top side of the top frame 501, and the other end is fixed to the nylon push block 708. The top arm 707 and the nylon push block 708 will not interfere with the clamping of the wheel hub and the tire and the removal of the tire after it is installed on the wheel hub.

[0081] like Figure 8 、 Figure 9 and Figure 10 As shown, a card pressing assembly 5 is also installed at the top of the bottom frame body 1, which is used to realize the installation of the tire and the wheel hub after the rotating frame 203 is rotated to the horizontal position. The top of the bottom frame body 1 is fixedly connected in pairs with a top frame 501, and a top fixing plate 502 is fixed between the inner top ends of the top frames 501. A card pressing slide 503 is arranged and fixed in the main body of the top fixing plate 502. The card pressing slide 505 is slidably connected to the card pressing slide 503. The top connecting plate 504 is fixedly connected to the top end of the card pressing slide 505, and the card pressing push plate 507 is fixedly connected to the bottom end of the card pressing slide 505.

[0082] A pressing hydraulic cylinder 506 is fixed to the middle of the top of the top fixing plate 502, and the top of the telescopic rod of the pressing hydraulic cylinder 506 is fixedly connected to the top connecting plate 504;

[0083] A middle fixed rotating seat 508 is fixed to the middle part of the main body of the card pressing and pushing plate 507, an adjusting shaft 511 is fixed to the middle part of the top of the rotating seat 509, and a thrust bearing 515 is sleeved and installed on the bottom end of the outer side of the adjusting shaft 511. The adjusting shaft 511 is rotatably connected to the middle fixed rotating seat 508, and the top end of the thrust bearing 515 is in contact with the bottom surface of the card pressing and pushing plate 507, which can improve the support strength of the card pressing and pushing plate 507 for the downward movement of the rotating seat 509;

[0084] By activating the card pressing hydraulic cylinder 506, the movement of the telescopic rod of the card pressing hydraulic cylinder 506 can drive the component formed by the top connecting plate 504 and the card pressing push plate 507 to move guided by the sliding fit formed by the card pressing slide 505 and the card pressing slide 503;

[0085] An adjusting gear 512 is fixed to the top of the adjusting shaft 511, a servo motor 513 is fixed to the top of the card pressing and pushing plate 507, a driving gear 514 is fixed to the shaft of the servo motor 513, and the driving gear 514 is meshed with the adjusting gear 512;

[0086] The bottom end of the rotating seat 509 is fixed with a pair of pressing blocks 510;

[0087] By starting the servo motor 513 to drive the driving gear 514 and the adjusting gear 512 to form a cooperative transmission, the rotating seat 509 and the pressing block 510 can be driven to rotate with the middle fixed rotating seat 508 as the reference. The purpose of the rotation of the pressing block 510 is to rotate the two sets of pressing blocks 510 to a position suitable for pushing the tire downward according to the actual position of the tire falling relative to the wheel hub when the rotating frame 203 is in the horizontal position;

[0088] That is, the two sets of pressing blocks 510 are rotated and adjusted to positions evenly spaced on both sides of the intersecting position between the tire and the wheel hub, so that the tire can be evenly pressed downward by the two sets of pressing blocks 510;

[0089] After the two sets of pressing blocks 510 come into contact with the top of the tire, as the pressing push plate 507 moves downward, the pressing blocks 510 exert force on the tire, which can first drive one side of the tire to be clamped to the outside of the wheel hub, and then clamp the other side of the tire to the outside of the wheel hub;

[0090] It should be noted that, since the transmission ratio of the rotating frame 203, the bottom support block 304 and the top support block 402 remains unchanged during rotation adjustment, and the distance between the two sets of pressing blocks 510 also remains unchanged, the device is only suitable for the installation operation of tires and wheels of a certain size.

[0091] like Figure 16 As shown, a laser scanning module 8 is also installed in the rotating base 509, which can scan the relative position of the tire and the wheel hub during operation. Mounting plates 801 are fixed on both sides of the middle of the outer end of the rotating base 509, and laser scanning probes 802 are mounted and fixed on the outer ends of the mounting plates 801;

[0092] When the rotating seat 509 and the pressing block 510 rotate, the relative position of the tire and the wheel hub can be scanned in real time by utilizing the rotating action of the laser scanning probe 802;

[0093] The laser scanning probe 802 can be used to scan the initial position of the tire when it falls to contact the wheel hub, so as to guide the initial contact position of the two sets of pressing blocks 510 with the outside of the tire, thereby improving the success rate of the pressing blocks 510 pushing one side of the tire to be clamped onto the outside of the wheel hub.

[0094] Preferably, if Figure 11 and 12 As shown, a plug-in stabilizing member 6 is installed between the card pressing and pushing plate 507 and the rotating frame 203, which can improve the safety and stability of the tire during the process of using the card pressing block 510 to press down the tire. The plug-in column connecting frame 602 is symmetrically fixed to the two ends of the card pressing and pushing plate 507. The two ends of each group of plug-in column connecting frames 602 are vertically fixed with plug-in columns 603. The top two sides of the rotating frame 203 are fixed with a pair of follower fixed sleeves 601. After the rotating frame 203 is rotated backward to the horizontal position, the follower fixed sleeve The position 601 is just opposite to the insertion column 603, and when the card pressing plate 507 moves down to a certain position, that is, when the bottom end of the card pressing block 510 contacts the outside of the tire, the insertion column 603 can be inserted into the follower fixed sleeve 601, so that when the tire is clamped to the outside of the wheel hub by using the downward card pressing block 510, the rotating frame 203 can be stably maintained in a horizontal state, and at the same time, it can also protect the mechanism that drives the rotating frame 203 to rotate when the card pressing block 510 moves downward and applies force.
