Description

Technical Field

[0001] This invention relates to the field of track vehicle technology, and more specifically to an amusement track vehicle with toothed hole meshing transmission. Background Technology

[0002] There are many types of recreational track vehicles, each with different drive methods. Common ones include chain drive, rope traction drive, and rack and pinion drive. Chain drives are prone to wear and loosening, leading to slippage and breakage. They also have poor positioning accuracy and limited load-bearing capacity. Rope traction is susceptible to strand breakage and requires extremely complex safety braking systems, significantly increasing operating costs. While rack and pinion drives do not have these problems, they require high machining precision and have high operating costs. Furthermore, the rack has different contact angles at turns of different radii, directly increasing design and manufacturing complexity. The rack is also prone to dust accumulation on the tooth surface, accelerating wear and reducing the equipment's lifespan. Additionally, the tooth height of rack and pinion vehicles is often small, making them prone to slippage on tracks with steep inclines. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an entertainment track vehicle that is simple in structure, low in cost, and safe and reliable in operation.

[0004] The technical solution of the present invention is: an amusement track vehicle, including a vehicle body, wheels, a drive mechanism and a track. The vehicle body is equipped with a braking device. The drive mechanism includes a wheel, a drive device and a perforated plate. The wheel has at least one ring of nipple-shaped drive teeth evenly distributed on its circumference. The wheel is rotatably connected to the frame of the vehicle body by the drive device. The perforated plate has multiple circular tooth holes arranged longitudinally to mate with the drive teeth of the wheel. The perforated plate is laid longitudinally between the tracks. The drive teeth at the bottom of the wheel are inserted into the tooth holes of the perforated plate. The drive device makes the vehicle body travel on the track by mate between the drive teeth of the wheel and the tooth holes of the perforated plate.

[0005] The technical advantages of this invention are: simple structure, convenient manufacturing, easy assembly, low maintenance cost, strong environmental adaptability, high safety redundancy, and long service life. It is particularly suitable for track equipment with steep gradients, long distances, and heavy loads, significantly improving the stability and safety of equipment operation. The double-row staggered tooth arrangement structure achieves alternating meshing, eliminating transmission dead points, and ensuring continuous and smooth alternating linear and turning motion. The perforated plate only requires punching or drilling, simplifying processing and reducing costs. The meshing process is continuous and smooth, with low impact, low noise, minimal running shock, low wear, and a longer service life. It is especially suitable for applications such as amusement equipment, track trolleys, and sightseeing vehicles. Attached Figure Description

Detailed Implementation

[0007] like Figures 1 to 4 As shown, an amusement track vehicle includes a body, wheels, a drive mechanism, and a track 1. The body is equipped with a braking device, and the track is double-rail. The drive mechanism includes a wheel 2, a drive unit 3, and a perforated plate 4. The wheel 2 has at least one ring of nipple-shaped drive teeth 5, each with a hemispherical end, evenly distributed on its circumference. The wheel 2 is rotatably connected to the frame 6 of the body via the drive unit 3. The perforated plate 4 has multiple circular toothed holes 7 arranged longitudinally to engage with the drive teeth 5 of the wheel 2. The perforated plate 4 is laid longitudinally between the tracks 1. The drive teeth 5 at the bottom of the wheel 2 are inserted into the toothed holes 7 of the perforated plate and mesh with them. The drive unit 3 uses the engagement of the drive teeth 5 of the wheel 2 with the toothed holes 7 on the perforated plate 4 to make the vehicle travel on the track 1. This design has the advantages of high positioning accuracy and strong load-bearing capacity of rack and pinion drives, lower cost, and greater resistance to dirt. Unlike racks, the toothed holes do not accumulate dust and are less prone to wear. The meshing of the toothed holes provides a larger contact surface in curves compared to straight teeth, allowing for smaller turning radii. It features higher tooth height and strength, ensuring reliable tooth hole connection. The drive unit can be an electric motor, engine, or other similar device. If an electric motor is used, it connects to the wheel's shaft via a reducer to achieve speed matching and direction adjustment.

[0008] The wheel 2 and drive unit 3 are fixed on the hinge seat 8. One end of the hinge seat 8 is hinged to the frame 6, and the other end is connected to the frame 6 through a buffer device 9. The buffer device can be a commonly used structure such as a spring or a rubber block. In this example, a spring combined with a spring seat and a guide rod for limiting is used. The buffer device can also ensure a stable connection between the wheel drive teeth and the perforated plate when the vehicle body vibrates.

[0009] The track 1 is made of channel steel with a "U" shaped cross-section. The two track 1 grooves are arranged opposite each other. The wheel includes a support wheel 10 and a clamping wheel 11. The support wheel 10 and the clamping wheel 11 abut against the bottom plane and side surface of the groove of the track 1, respectively. The wheel is connected to the frame 6 through a wheel frame 12. When a hinge seat is provided, the wheel disc and drive device are first connected to the wheel frame through the hinge seat, and then connected to the frame. The support wheel is used to bear the weight of the vehicle and can also work with the top plane of the channel steel groove to limit the movement of the vehicle body on the track.

[0010] The wheel frame 12 is sway-connected to the chassis 12 via a vertical shaft 13, allowing the wheels to better adapt to curves.

[0011] The wheel 2 and drive unit 3 are connected to the wheel frame and then to the vehicle frame 6 via the wheel frame 12. The wheel 2 can make a slight oscillation by twisting the wheel frame, which makes the wheel drive teeth and tooth holes more accurately positioned and reduces friction when cornering.

[0012] The drive teeth 5 on the wheel 2 have two rings, and the tooth holes 7 on the perforated plate 4 correspond to two sets. The wheel can adopt a double-wheel structure with one row of teeth on each wheel or a single-wheel double-row tooth structure. At curves, the outer ring hole spacing is large. During design, the increased size of the outer ring can be evenly distributed into the outer ring hole spacing, and the hole diameter can be appropriately increased or allowed to adapt naturally after operation. When the tooth pitch of a single-row tooth transmission is large, there may be a transmission dead point, resulting in discontinuous motion and large meshing impact. The double-row tooth design can appropriately increase the tooth pitch to effectively solve the above problems.

[0013] The two rings of drive teeth 5 on the wheel 2 and the two sets of tooth holes 7 on the perforated plate 4 are all staggered. The double-row staggered tooth structure can automatically compensate for installation errors and wear gaps. When the wheel rotates, the drive teeth alternately insert into the tooth holes of the perforated plate to form a meshing transmission, making the operation smoother.

[0014] The vehicle body is equipped with a reverse braking device, which includes a ratchet frame 14 and a follower ratchet 15 that can rotate unidirectionally with the vehicle's direction of travel. One end of the ratchet frame 14 is hinged to the vehicle frame 6, which can swing back and forth (the vehicle's direction of travel is forward). The ratchet 15 is located at the other end of the ratchet frame 14 and abuts against the perforated plate 4. The ratchet frame 14 has several braking teeth 16 behind the ratchet 15 that correspond to the toothed holes 7 of the perforated plate 4. A limiting part 17 is provided at the hinge point between the ratchet frame 14 and the vehicle frame 6, so that the ratchet frame 14 can only be lifted backward under the restriction of the limiting part 17. The ratchet drags on the perforated plate, and moves with the vehicle when moving forward. When the vehicle moves backward, the ratchet stops rotating and rubs against the surface of the perforated plate, causing the ratchet frame to swing forward to the limited position of the limiting part. At this time, the braking teeth are inserted into the toothed holes of the perforated plate to achieve the reverse braking function.

[0015] The braking device includes a brake lever 18 and a brake block 19. The lower part of the brake lever 18 is hinged to the frame 6. The brake block 19 is horizontally set and connected to the frame 6 through a connecting rod 20, forming a four-bar linkage with the frame 6. The brake block 19 is also connected to the frame 6 through a tension spring 21, which keeps the brake block 19 in a raised state. The brake lever 18 is connected to the brake block 19 through a pull cable 22 and a guide wheel 23. Moving the brake lever 18 through the wire 22 can make the brake block 19 come into contact with the orifice plate 4 for friction.
