Description

Technical Field

[0001] The utility model relates to the technical field of amusement vehicles, and particularly relates to a crawler-type amusement vehicle running system with anti-drop multi-wheel independent suspension. Background Art

[0002] With the improvement of living standards, more and more people choose to go to amusement parks during holidays to relax and relieve stress, resulting in overcrowded tourists in amusement parks during holidays. At the same time, many parents take their children to amusement parks. The park area is large, and children are too young to walk for a long time. Therefore, a large number of amusement vehicles are equipped in the park to transport tourists to various amusement projects.

[0003] Existing amusement vehicles have high safety, but the shock absorption effect of this operation vehicle is poor. When driving on uneven roads, it is easy to generate large vibrations, resulting in a poor experience for customers. In addition, although the crawler-type running system has excellent terrain adaptability, the crawler is prone to fall off during high-speed turning or obstacle crossing. In particular, the axial locking failure of the driving wheel is the main cause of derailment. Especially when the crawler bears lateral impact, the traditional retaining ring structure is prone to elastic deformation, causing the crawler teeth to disengage from the driving wheel. Frequent crawler shedding not only causes operation interruption, but also leads to abnormal wear of core components such as hinge pins and axle shafts. Especially in amusement park facilities, the maintenance cost of the crawler is high.

[0004] Therefore, it is urgent to develop a crawler-type amusement vehicle running system with anti-drop multi-wheel independent suspension to fundamentally solve the above technical contradictions. Content of the Utility Model

The utility model provides the following technical solutions, including: a frame body, a bracket, a road wheel rotating shaft, a road wheel assembly, a carrier roller assembly, a shock absorption spring, a crawler, a driving wheel and an anti-drop device; Brackets are symmetrically fixed on both sides of the frame body. Several groups of carrier roller assemblies are symmetrically arranged on the brackets. A plurality of groups of equally spaced shock absorption springs are arranged at the lower end of the brackets. Each group of shock absorption springs is connected to the road wheel assembly through a group of road wheel rotating shafts, forming an independent suspension structure; The crawler surrounds the outer edges of the road wheel assembly, the carrier roller assembly and the driving wheel; The driving wheel is located at one end of the bracket, connected with a driving component and meshed with the crawler; The anti-drop device is arranged outside the driving wheel and axially locks the driving wheel, including an anti-drop retaining ring coaxially fixed with the driving wheel and a limiting protrusion on the inner wheel edge of the crawler.

[0006] Further, the anti - detachment retaining ring is connected to the driving wheel through a key - slot bolt, and an elastic gasket is provided between the anti - detachment retaining ring and the driving wheel; Further, the anti - detachment retaining ring is provided with an annular groove structure corresponding to the limiting protrusion, and the annular groove structure is in interference fit with the outer end face of the driving wheel; Further, the height of the limiting protrusion is one - half to three - quarters of the height of the crawler tooth.

[0008] Further, the crawler adopts a metal - rubber articulated crawler.

[0009] Further, buffer mechanisms are provided on both of the two brackets. The buffer mechanism includes a guide wheel assembly and a tensioner.

The idler wheel assembly 5 supports the upper part of the crawler belt 7 to prevent sagging; multiple groups of independent shock-absorbing springs 6 enable each road wheel to independently respond to road surface undulations, greatly enhancing the adaptability to complex road surfaces and eliminating the risk of vehicle body tilt.

[0019] The crawler belt 7 surrounds the outer edges of the road wheel assembly 4, the idler wheel assembly 5, and the drive wheel 8; The drive wheel 8 is located at one end of the bracket 2, connected with a drive component and meshed with the crawler belt 7; The anti-drop-off device is arranged outside the drive wheel 8 and axially locked with the drive wheel 8, and includes an anti-drop-off retaining ring 9 fixedly connected coaxially with the drive wheel 8 and a limiting protrusion 10 on the inner wheel rim of the crawler belt 7.

[0020] In this embodiment, the vehicle weight is borne by the road wheel assembly 4, the idler wheel assembly 5 maintains the shape of the crawler belt 7, and the drive wheel 8 provides power. The short wheelbase layout and the metal-rubber articulated crawler belt 7 achieve the minimum turning radius and low-noise operation, meeting the high maneuverability requirements of the narrow space in the amusement park; and a limiting structure is formed by the limiting protrusion 10 being embedded in the annular card slot of the anti-drop-off retaining ring 9. When the crawler belt 7 is subjected to a lateral impact, the protrusion-slot structure rigidly resists axial displacement, solving the problem of derailment during high-speed turning.

[0026] Preferably, a footrest 16 is further provided in the middle of the bracket 2.

[0027] In the utility model, the anti-drop ring rigidly connected to the driving wheel and the limiting convex on the inner side of the crawler in the anti-drop device effectively restrict the axial displacement of the crawler under high-speed steering or lateral impact. The anti-drop ring and the driving wheel are connected by a keyway bolt and supplemented with an elastic gasket to ensure firm connection and absorb part of the impact to prevent the failure of axial locking.

[0028] Through the design of multiple independent suspensions, each idler assembly is connected to an independent shock-absorbing spring through an idler shaft, enabling each idler to independently respond to road bumps, greatly improving the shock-absorbing effect on uneven roads. The independent suspension effectively absorbs and disperses the impact force, greatly reducing the vibration transmitted to the vehicle body and significantly improving the riding comfort of passengers. The buffer mechanism ensures that the crawler always maintains an appropriate tension, preventing jitter, noise or potential derailment risks caused by slack, further ensuring smooth driving.

[0029] The utility model effectively solves the core problem of frequent crawler shedding, greatly reducing the resulting operation interruptions and equipment downtime; preventing derailment fundamentally avoids abnormal wear of hinge pins, axle shafts, driving wheel teeth and the crawler itself caused by abnormal crawler displacement, significantly extending the service life of core components. The enhanced driving stability and anti-shedding ability directly improve the operation safety of the amusement vehicle and ensure the safety of passengers.

[0030] [[ID=第十六]]In summary, the utility model effectively solves the core pain points of poor shock absorption and easy crawler shedding of existing crawler-type amusement vehicles, improves comfort through multiple independent suspensions, ensures operation reliability and safety through an innovative rigid anti-drop device, and significantly reduces maintenance costs.
