Embodiment 1

[0040] combine figure 1 and figure 2 As shown, this embodiment provides a special-shaped track wheel, which includes a wheel frame, a plurality of guide wheels 31 , an endless track 4 and a driving mechanism 5 .

[0041] Wherein, the wheel frame includes a lower casing 2 and an upper casing 1, and the lower casing 2 is provided with a plurality of spring steel sheets 3 to form a suspension for installing guide wheels 31, and each guide wheel 31 passes through a spring. The steel sheet 3 is mounted on the lower casing 2, and in this embodiment, the spring steel sheet 3 is preferably a spring steel sheet.

[0042] recombine image 3 , Figure 4 and Figure 6 As shown, wherein, one end of the spring steel sheet 3 installed on the lower housing 2 of the wheel frame is defined as the installation end, and the other end is the movable end.

[0043] The lower housing 2 is provided with a slot 22. At the same time, the installation end of the spring steel sheet 3 is bent at two ...

Embodiment 2

[0058] combine Figure 7 and Figure 8 As shown, this embodiment provides a crawler off-road motorcycle, including a front frame 10, a rear frame 20, and a beam assembly 60 connecting the front and rear frames.

[0059] The front frame 10 includes the special-shaped track wheel described in Embodiment 1, and a handle 101 is provided on the upper end of the upper housing, so that the front end of the special-shaped track wheel can be swung by the handle to turn. Front vehicle frame 10 loads are less, for considering turning to flexibly, only be provided with a spring steel sheet on its wheel frame bottom surface, so that the endless track line contacts ground.

[0060] This rear vehicle frame 20 is also provided with a above-mentioned special-shaped crawler wheel, and its difference is that the upper end of the rear vehicle frame 20 is provided with a vehicle seat 201, and the rear vehicle frame 20 has a larger load, and three spring steel sheets are provided on the bottom sur...

Embodiment 3

[0067] This embodiment provides an off-road vehicle, which includes a vehicle frame on which four sets of the above-mentioned special-shaped track wheels are arranged; wherein, two sets of special-shaped track wheels are arranged side by side at the front end of the vehicle frame to form a dedicated front wheel. , the two groups are located at the rear end of the frame to support the rear wheels.

[0068] Among the two special-shaped crawler wheels located at the front end of the vehicle frame, a vertically arranged wheel frame steering shaft is provided on the top of each wheel frame, and the wheel frame steering shaft is rotatably inserted on the vehicle frame; Corresponding to the steering shaft of the wheel frame, the frame is also equipped with a steering system to drive its linkage steering;

[0069] Among the two special-shaped track wheels located at the rear end of the frame, the top of each wheel frame is fixed on the frame by bolt locking to realize fixed installati...

Abstract

The invention provides a special-shaped crawler wheel by taking a bent spring steel sheet as a supporting suspension and a crawler motorcycle and a cross-country vehicle with the same which are suitable for any transport means. The special-shaped crawler wheel comprises a wheel carrier, a plurality of guide wheels, an annular crawler belt and a driving mechanism, a spring steel sheet is arranged on the wheel carrier, the spring steel sheet serves as the suspension, the guide wheels are installed on the wheel carrier, and the annular crawler belt is supported. According to the special-shaped crawler wheel, the spring steel sheet serves as the suspension mechanism, the special-shaped crawler wheel is small in dead weight, free of noise and large in deformation amount and can adaptively stretch or swing and deform according to the actual situation of a road surface, the application performance of the crawler is improved, and the problem that an off-road vehicle wheel is poor in obstacle crossing capacity is solved.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and specifically relates to a special-shaped track wheel suitable for passage in harsh conditions such as stairs, steps, steep slopes, mountains and wasteland, and a tracked motorcycle and off-road vehicle equipped with the special-shaped track wheel. Background technique [0002] The inventor of this case saw news reports on mountain forest rescue and mountain patrolling, and could not borrow transportation, so he could only advance on foot. Frontier patrols had to walk for several hours every day, and mountain rescue teams had to shuttle for several hours to reach the rescue site. He was very emotional. Heavy, the idea of ​​inventing a means of transportation to solve their problems was born. [0003] Currently used off-road motor vehicles are generally only suitable for running on pits or less raised ground. Raised, and the tire diameter is limited, easy to fall into the pit. [0004] The c...
