Description

Technical Field

[0001] This invention relates to the field of vehicle axle technology, specifically to a vehicle axle coupled vibration device. Background Technology

[0002] The axle (also called the vehicle frame) is connected to the suspension and the vehicle frame (or monocoque body). Wheels are mounted at both ends of the axle. Its function is to transmit the forces and torques between the vehicle frame (or monocoque body) and the wheels in all directions. When crossing a bridge, the vibration of the vehicle is transmitted to the bridge, causing the bridge to vibrate (forced vibration). When the vibration frequency of the vehicle is close to or the same as the natural frequency of the bridge, it will cause the bridge to resonate. In trucks, the leaf springs in the rear cargo area are the main functional components for axle damping.

[0003] There are many types of axles on the market today, which can basically meet people's needs. However, there are still some shortcomings. During operation, the huge working power of the existing axles will cause vibration of the vehicle body and axle. It is difficult to adapt and adjust the axle coupling vibration according to different road conditions, which reduces the driving comfort of the vehicle. Summary of the Invention

[0009] Preferably, through holes are provided on both outer walls of the first connecting arm, and both ends of the positioning crossbar extend to the outside of the through holes, and the outer diameter of the positioning crossbar is the same as the diameter of the through holes.

[0010] Preferably, the damping structure includes a main hinge shaft mounted on the outer wall of the positioning base and a secondary hinge shaft mounted on the bottom end of the inverted U-shaped steel frame, and a damping damper is movably installed between the main hinge shaft and the secondary hinge shaft.

[0011] Preferably, a baffle is fixedly connected to one end of the surface of the shock absorber and the top of the piston rod, and a spring is installed between the two sets of baffles. The spring is a helical spring or a wave spring.

[0012] Preferably, the power supply assembly consists of a power driver, a power transmitter, and a secondary shaft body rotatably mounted on the inner wall of the power housing. One end of the secondary shaft body is fixed with a driven worm gear, and the other end of the secondary shaft body is fixedly connected to one end of a ball threaded column.

[0013] Preferably, bearing mounting seats are fixed on both sides of the bottom of the power housing, and a power horizontal shaft is installed between the two sets of bearing mounting seats. The two ends of the power horizontal shaft are rotatably connected to the two inner walls of the power housing, and both ends of the surface of the power horizontal shaft are provided with driving worm gears. The threads of the two sets of driving worm gears are opposite, and the driving worm gears mesh with the driven worm gears.

[0014] Preferably, the power drive includes an arc-shaped tube fixedly connected to the inner wall of the power housing, a servo motor is mounted on the top of the arc-shaped tube, and a drive shaft is mounted on the output end of the servo motor via a coupling.

[0015] Preferably, the power transmitter includes a drive bevel gear mounted on the surface of the drive shaft. A rotary positioner is fixedly connected to the outer wall of the power housing above the drive bevel gear. The rotary positioner includes a bidirectional positioning block fixedly connected to the outer wall of the power housing. A secondary bearing seat is installed at the center of the bidirectional positioning block. A central shaft is installed inside the secondary bearing seat.

A driven bevel gear is fixedly connected to one end of the surface of the power horizontal shaft. The driven bevel gear meshes with the upper bevel gear.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the vehicle-axle coupling vibration device has a compact structure, stable operation, effectively filters the working vibration of the road surface, improves the shock absorption and vibration resistance performance of the device, and enables the device to switch between independent suspension and non-independent suspension states to meet the usage requirements of different road driving conditions.

[0017] (1) By setting up a structure that cooperates with steel leaf springs and shock absorption structures, the main components formed by steel leaf springs and shock absorption structures reduce the driving vibration of the road surface on the axle and frame. At this time, the coupling pair and the guide positioner are in a separated state, that is, the steel leaf springs, shock absorption structures and the second axle shock absorption components can all perform shock absorption treatment on the pothole road conditions, effectively filter the working vibration of the road surface, and improve the shock absorption and vibration resistance performance of the device.

[0018] (2) By setting up a structure with a power supply component and a screw drive, the power drive and the drive worm are driven to rotate by the power drive and the power transmitter. The drive worms at both ends of the power horizontal shaft drive in opposite directions. At this time, the power supply component drives the two sets of screw drives to work synchronously, that is, the guide positioner moves horizontally. At this time, the coupling positioning column is pushed into the coupling hole of the U-shaped connecting frame. At this time, the inner groove and the straight spline cooperate with each other. The inner groove and the straight spline improve the stability of the coupling positioning column and the coupling component, which can lock the first connecting arm. At this time, the steel leaf springs and shock absorption structures on both sides of the inverted U-shaped steel frame become a whole, that is, similar to the function of non-independent suspension, so that the device can adapt to the driving conditions of the smooth road surface, and the device can switch between independent suspension and non-independent suspension to meet the usage requirements of different road driving conditions.

[0019] (3) By setting up a structure with a power drive and a power transmitter working together, the operator turns on the power drive, that is, the servo motor drives the drive shaft and the active bevel gear in sequence. The active bevel gear drives the lower bevel gear, the central shaft and the upper bevel gear to rotate. Then the upper bevel gear drives the driven bevel gear, the power horizontal shaft and the active worm gear at both ends of the power horizontal shaft to rotate synchronously. During this process, the rotary positioner and the secondary bearing seat improve the rotational stability of the central shaft, and the secondary bearing seat supports the central shaft. Thus, the power transmitter and the power drive form a power source, so that the first connecting arms on both sides of the two sets of inverted U-shaped steel frames can be synchronously driven and locked. Its structure is compact and its operation is stable. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Example 1, by Figures 1 to 8 The present invention includes an inverted U-shaped steel frame 1, on which main bearing seats 2 are fixedly connected to both outer walls. A positioning cross column 3 is rotatably installed inside the main bearing seats 2. A first connecting arm 4 is installed on one side of the inverted U-shaped steel frame 1 through the positioning cross column 3. A trapezoidal seat 5 is fixedly connected to the top of the first connecting arm 4. Through holes 401 are opened on both outer walls of the first connecting arm 4. Both ends of the positioning cross column 3 extend to the outside of the through holes 401. The outer diameter of the positioning cross column 3 is the same as the diameter of the through holes 401.

[0031] Several sets of leaf springs 6 with successively decreasing lengths are installed at the bottom of the trapezoidal seat 5. The bottom of the leaf springs 6 is fixedly connected to the positioning base 7. The outer wall of one side of the positioning base 7 is movably connected to the bottom of the inverted U-shaped steel frame 1 through the shock absorption structure 8. The other side of the inside of the inverted U-shaped steel frame 1 is equipped with the second axle shock absorption component 9 through the positioning cross column 3. The leaf springs 6 and the shock absorption structure 8 on both sides of the inverted U-shaped steel frame 1 can be used to reduce the vibration of the road surface.

[0032] The bottom end of the first connecting arm 4 is provided with a coupling component 13. The coupling component 13 includes a U-shaped connecting frame 1301 installed on the outer wall of the first connecting arm 4 by a positioning pin 1302. The surface of the U-shaped connecting frame 1301 is provided with a coupling hole 1303. The interior of the coupling hole 1303 is evenly provided with four sets of inner grooves 1304. A rectangular plate 10 is fixed on the outer wall of one side of the inverted U-shaped steel frame 1. A horizontal plate 11 is fixed on the outer wall of one side of the rectangular plate 10. A power housing 12 is installed at the end of the horizontal plate 11 away from the outer wall of the rectangular plate 10. A guide locator for docking with the coupling component 13 is installed on the outer wall of one side of the rectangular plate 10 by a screw drive. The interior of the power housing 12 is provided with a power supply component for driving the two sets of screw drives to work synchronously.

[0033] The power supply assembly consists of a power drive 21, a power transmitter 22, and a secondary shaft body 26 rotatably mounted on the inner wall of the power housing 12.

[0034] The lead screw driver includes a ball screw 16 rotatably mounted on the outer wall of a rectangular plate 10. One end of the ball screw 16 extends into the interior of the power housing 12. A ball nut pair 17 is installed at the threaded end of the surface of the ball screw 16. The bottom end of the ball nut pair 17 is fixedly connected to the top end of the guide positioner. A transverse guide unit is provided on the outer wall of the rectangular plate 10 on one side of the ball screw 16. The transverse guide unit includes a guide column 14 mounted on the outer wall of the rectangular plate 10. The guide column 14 and the ball screw 16 are on the same vertical line. A guide sleeve 15 is slidably mounted on one end of the surface of the guide column 14. The bottom end of the guide sleeve 15 is fixedly connected to the top end of the ball nut pair 17.

[0035] The guide positioner includes a steel plate body 18 installed at the bottom of the ball nut pair 17. A coupling positioning post 19 is fixed on the outer wall of one side of the steel plate body 18 by a flange. Four sets of equally spaced straight splines 20 are evenly arranged on the outer circumferential surface of the coupling positioning post 19. Since the secondary shaft body 26 and the driving worm gear 25 mesh with each other, the secondary shaft body 26 drives the driven worm gear 27 and the guide positioner to work. That is, the secondary shaft body 26 drives the ball thread post 16 to rotate, so that the ball nut pair 17, the steel plate body 18, and the coupling positioning post 19 move horizontally. The coupling positioning post 19 is pushed into the coupling hole 1303 of the U-shaped connecting frame 1301. At this time, the inner groove 1304 and the straight spline 20 cooperate with each other. The inner groove 1304 and the straight spline 20 improve the engagement stability of the coupling positioning post 19 and the coupling pair 13, so as to lock the first connecting arm 4.

[0036] When the coupling component 13 and the guide positioner are connected, the leaf springs 6 and the shock absorption structure 8 on both sides of the inverted U-shaped steel frame 1 become a whole, which is similar to the function of a non-independent suspension. This allows the device to adapt to the driving conditions on a smooth road surface and switch between independent suspension and non-independent suspension to meet the usage requirements of different road driving conditions.

[0037] Example 2, based on Example 1, is... Figure 1 , Figure 2 and Figure 8 The shock absorption structure 8 includes a main hinge shaft 801 mounted on the outer wall of the positioning base 7 and a secondary hinge shaft 802 mounted on the bottom end of the inverted U-shaped steel frame 1. A shock absorber 803 is movably installed between the main hinge shaft 801 and the secondary hinge shaft 802. A baffle 804 is fixedly connected to one end of the surface of the shock absorber 803 and the top of the piston rod. A spring 805 is installed between the two sets of baffles 804. The spring 805 is a helical spring or a wave spring. During vehicle operation, the main components formed by the leaf spring 6 and the shock absorption structure 8 reduce the road surface vibration on the axle and the frame. At this time, the coupling sub-component 13 and the guide positioner are in a separated state.

[0038] Vibrations from the axle and road surface can cause the positioning base 7, leaf spring 6, and first connecting arm 4 to swing around the positioning cross column 3 as a whole. At this time, the damper 803 and spring 805 are in a stretched state, and the secondary hinge shaft 802 is the swing center of the damper 803, thereby effectively filtering the working vibration of the road surface and improving the damping and anti-vibration performance of the device.

[0039] Example 3, based on Example 1, is... Figure 4 , Figure 5 and Figure 6 As shown, a driven worm gear 27 is fixed at one end of the secondary shaft body 26, and the other end of the secondary shaft body 26 is fixedly connected to one end of the ball threaded column 16. Bearing mounting seats 23 are fixed on both sides of the bottom of the power housing 12. A power horizontal shaft 24 is installed between the two sets of bearing mounting seats 23. A driven bevel gear 2206 is fixedly connected to one end of the surface of the power horizontal shaft 24.

[0040] The two ends of the power horizontal shaft 24 are rotatably connected to the two inner walls of the power housing 12 respectively. Both ends of the surface of the power horizontal shaft 24 are provided with driving worm gears 25. The thread directions of the two sets of driving worm gears 25 are opposite. The driving worm gears 25 and the driven worm wheel 27 mesh with each other. When the vehicle travels to a smooth road surface, the staff drives the power horizontal shaft 24 and driving worm gears 25 to rotate through the power drive 21 and the power transmitter 22. The driving directions of the driving worm gears 25 at both ends of the surface of the power horizontal shaft 24 are opposite.

[0041] The power drive 21 includes an arc-shaped tube 2101 fixedly connected to the inner wall of the power housing 12. A servo motor 2102 is mounted on the top of the arc-shaped tube 2101. A drive shaft 2103 is mounted on the output end of the servo motor 2102 through a coupling.

[0042] The power transmitter 22 includes a drive bevel gear 2201 mounted on the surface of the drive shaft 2103. A rotary positioner 2202 is fixedly connected to the outer wall of the power housing 12 above the drive bevel gear 2201. The rotary positioner 2202 includes a bidirectional positioning block 2207 fixedly connected to the outer wall of the power housing 12. A secondary bearing seat 2208 is installed at the center position inside the bidirectional positioning block 2207. A central shaft 2203 is installed inside the secondary bearing seat 2208. The rotary positioner 2202 and the secondary bearing seat 2208 improve the rotational stability of the central shaft 2203. The secondary bearing seat 2208 supports the central shaft 2203.

[0043] The top and bottom ends of the central shaft 2203 are respectively equipped with a lower bevel gear 2204 and an upper bevel gear 2205. When the operator turns on the power drive 21, that is, the servo motor 2102, it drives the drive shaft 2103 and the active bevel gear 2201 in sequence. Then the active bevel gear 2201 drives the lower bevel gear 2204, the central shaft 2203, and the upper bevel gear 2205 to rotate. In turn, the upper bevel gear 2205 drives the driven bevel gear 2206, the power horizontal shaft 24, and the active worm gears 25 at both ends of the power horizontal shaft 24 to rotate synchronously.

[0044] The lower bevel gear 2204 meshes with the driving bevel gear 2201, and the driven bevel gear 2206 meshes with the upper bevel gear 2205. The power source is formed by the power transmitter 22 and the power driver 21, so that the first connecting arms 4 on both sides of the two sets of inverted U-shaped steel frames 1 can be synchronously driven and locked. Its structure is compact and its operation is stable.

[0045] In this embodiment, during vehicle operation, the main components formed by the leaf spring 6 and the shock-absorbing structure 8 reduce the road vibrations on the axle and frame. At this time, the coupling sub-component 13 and the guide positioner are separated. Both the leaf spring 6 and the shock-absorbing structure 8 on both sides of the inverted U-shaped steel frame 1 can dampen uneven road conditions. Vibrations from the axle and road surface can cause the positioning base 7, leaf spring 6, and the first connecting arm 4 to swing around the positioning crossbar 3. At this time, the shock-absorbing damper 803 and the spring 805 are in a stretched state, and the secondary hinge shaft 802 is the damper 803. The oscillating center effectively filters the working vibration of the road surface, improving the shock absorption and anti-vibration performance of the device. When the vehicle travels on a smooth road surface, the operator drives the power horizontal shaft 24 and the driving worm 25 to rotate through the power drive 21 and the power transmitter 22. The driving worms 25 at both ends of the surface of the power horizontal shaft 24 drive in opposite directions. Taking the left driving worm 25 as an example, since the secondary shaft body 26 and the driving worm 25 are meshed with each other, the secondary shaft body 26 drives the driven worm wheel 27 and the guide positioner to work. That is, the secondary shaft body 26 drives the ball threaded column 16 to rotate, so that the ball nut pair 17, the steel plate body 18, and the coupling positioning column are rotated. 19. The device moves horizontally, at which point the coupling positioning post 19 is pushed into the coupling hole 1303 of the U-shaped connecting frame 1301. The inner groove 1304 and the straight spline 20 then engage, improving the stability of the coupling positioning post 19 and the coupling sub-part 13, thus locking the first connecting arm 4. At this point, the leaf springs 6 and the shock-absorbing structure 8 on both sides of the inverted U-shaped steel frame 1 become a single unit, functioning similarly to a non-independent suspension. This allows the device to adapt to driving conditions on smooth roads, switching between independent and non-independent suspension modes to meet different road driving conditions. When the demand is met, the staff turns on the power drive 21, that is, the servo motor 2102 drives the drive shaft 2103 and the active bevel gear 2201 in sequence. The active bevel gear 2201 then drives the lower bevel gear 2204, the central shaft 2203, and the upper bevel gear 2205 to rotate. In turn, the upper bevel gear 2205 drives the driven bevel gear 2206, the power horizontal shaft 24, and the active worm gears 25 at both ends of the power horizontal shaft 24 to rotate synchronously. Thus, the power transmitter 22 and the power drive 21 form a power source, so that the first connecting arms 4 on both sides of the two sets of inverted U-shaped steel frames 1 can be synchronously driven and locked. Its structure is compact and its operation is stable.
