Wheel-tracked freely switching gear train device

Abstract

The invention provides a wheel-tracked freely switching gear train device which comprises a wheel rim deformation system and a track system, wherein the wheel rim deformation system comprises a spindle, a bearing, a wheel rim bracket, a first clutch device, a telescopic mechanism, a wheel rim connector, a first driving gear, a third clutch device and a segmented wheel rim arc, wherein the first clutch device is installed on the spindle to control the wheel rim bracket and is disconnected from or connected with the spindle, the telescopic mechanism is installed on the wheel rim bracket, a first driven gear is installed at one end of the telescopic mechanism, the wheel rim connector is fixedly connected with the other end of the telescopic mechanism, the first driving gear is in sleeved on the spindle in an idle way, the third clutch device is fixedly connected with the first driving gear, one end of the segmented wheel rim arc is connected with the wheel rim bracket, the other end of the segmented wheel rim arc is connected with the wheel rim connector, and the first driven gear is meshed with the first driving gear. The wheel-tracked freely switching gear train device realizes free switching between a round wheel and a track in a vehicle walking device so that a vehicle can switch the round wheel or the track at any time according to different road conditions, thereby enhancing the vehicle driving performance and increasing a vehicle application range.

Description

technical field [0001] The invention belongs to the field of vehicle running devices, and in particular relates to a driving wheel train device which can adapt to the mutual conversion operation of a circular wheel and a crawler belt. Background technique [0002] As we all know, in the running gear of the vehicle, the round wheel has higher flexibility and higher speed performance than the track, but the track has higher off-road performance than the round wheel. These two kinds of running devices have their own advantages. When vehicles with round wheels as running devices, especially rescue vehicles, encounter special road conditions, such as landslides, sandy or muddy grounds, they cannot move forward. When the vehicle that is a walking device encounters a flat, high-quality road condition, it is often very slow. Usually, circular wheels and crawler tracks cannot exist in the same set of running gear simultaneously, and taking into account the advantages of these two as...

Problems solved by technology

These two kinds of running devices have their own advantages. When vehicles with round wheels as running devices, especially rescue vehicles, encounter special road conditions, such as landslides, sandy or muddy grounds, they cannot move forward. Vehicles with running gear tend to be slow when encountering flat, high-quality road conditions

Under normal circumstances, it is impossible for circular wheels and crawlers to exist in the same set of running gear at the same time. Taking into account the advantages of these two aspects, this greatly restricts the scope and use of most vehicles.
