Description

Three-wheel combined anti-skid tyre

Technical Field

The invention relates to an antiskid tire, in particular to a three-wheel combined antiskid tire which is mainly suitable for vehicles such as disabled vehicles, military vehicles, off-road vehicles, sanitation vehicles and the like.

Background

The tire is one of the important parts on the vehicle, and plays roles of supporting the whole weight of the vehicle, bearing the load of the vehicle, transmitting the torque force of traction and braking, ensuring the adhesion of the vehicle to the road surface, reducing and absorbing the vibration and impact force of the vehicle during running and the like. The conventional vehicle is generally provided with four tires, each tire is independent, the tire is suitable for running on a common paved road surface, if the vehicle runs on some special road surfaces, such as a sunk road surface, a deep pit, a road surface with a round and bone-like shape, stairs climbing and the like, the conventional tire cannot pass through the road surfaces, and in addition, the conventional vehicle cannot run normally once one tire is punctured or air leaks, and the vehicle can run normally only after the tire is replaced.

Disclosure of Invention

The invention discloses a three-wheel combined antiskid tyre, which is characterized in that two or four groups of three-wheel combined antiskid tyres are arranged on a vehicle, if two groups of three-wheel combined antiskid tyres are adopted, the tyres are arranged at two front wheel positions of the vehicle, if four groups of three-wheel combined antiskid tyres are adopted, each group is arranged at each position of four tyres of the vehicle, when the vehicle normally runs, two wheels of each group of three-wheel combined antiskid tyres are contacted with the ground, when the power of the vehicle drives a rotating shaft to rotate, the rotating shaft drives a main gear to rotate, the main gear is meshed with a pinion gear (a gap is reserved between a clutch plate and the main gear and the pinion gear), the main gear drives three pinion gears to rotate around a connecting shaft, each pinion gear drives each wheel to rotate, wherein two wheels which are contacted with the ground automatically rotate to drive the vehicle to normally run, and the other wheel which is not contacted with the ground independently idle, when the vehicle passes through a special road surface (such as a pothole road surface, a riprap road surface, a ladder lattice and the like), the rotating disc is manually pulled to rotate for a certain angle, the rotating disc drives the left arc-shaped clutch bevel blade to rotate, the left arc-shaped clutch bevel blade is in contact with the right arc-shaped clutch bevel blade (the left arc-shaped clutch bevel blade and the right arc-shaped clutch bevel blade are in an arc shape, the upper part of the left arc-shaped clutch bevel blade is thicker and protrudes to be gradually thinner to the lower part, the lower part of the right arc-shaped clutch bevel blade is thicker and protrudes to be gradually thinner to the upper part), when the left arc-shaped clutch bevel blade rotates, the thicker part of the upper part of the left arc-shaped clutch bevel blade rotates downwards gradually and is matched with the thicker part of the lower part of the right arc-shaped clutch bevel blade so as to extrude the right arc-shaped clutch bevel blade to move rightwards, the right arc-shaped clutch bevel blade pushes, because the clutch plate is clamped with the split gears, the main gear is driven by the rotating shaft to rotate, the main gear cannot drive the split gears to rotate around the connecting shaft, but three split gears synchronously revolve around the main gear, and each split gear drives the wheels to revolve the same (namely three wheels sequentially rotate forwards to be contacted with the ground), so that the vehicle can more easily cross a concave ditch and climb up a ladder lattice and other complex terrains; when the vehicle normally runs on a common road surface, if one wheel is punctured or leaks air, the rotating disc can be shifted, the wheels are in a clutch state, the three wheels rotate forward in sequence, when the punctured wheels rotate to the uppermost part for standby, and when the other two good wheels are in contact with the ground, the rotating disc is shifted reversely, so that the wheels are disengaged from the clutch state, and the two good wheels are in contact with the ground, thereby ensuring the normal running of the vehicle.

The invention relates to a three-wheel combined type antiskid tire, wherein a limiting device comprises a limiting pin arranged on one side of a frame, an arc-shaped through hole is formed in a rotating disc, a limiting hole is formed in a second plane elastic bearing, and the limiting pin penetrates through the arc-shaped through hole to be matched with the limiting hole. The limiting pin is inserted into the limiting hole to limit the second plane elastic bearing, and the limiting pin penetrates through the rotating disc to avoid the limiting pin from interfering with the rotating disc, so that the rotating disc is provided with the arc-shaped through hole. The rotating disc is provided with a handle. People can drive the rotating disc to rotate through the handle, and the operation is convenient.
