ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to wheels and more particularly to a shock-absorbing safety wheel for motorized vehicles which provides shock-absorbing device in the rim of a wheel to greatly improve shock-absorbing effect for the motorized vehicles.
Conventional rim of wheel is made of rigid metallic material which has no any elasticity except the tire which is made of rubber and inflatable may provides a less shock-absorbing effect. Therefore, the automobiles, motorcycles or other motorized vehicles mostly depend upon the leaf spring, hydraulic devices or springs to obtain their shock-absorbing effect. It is known that the wheel may also provide the shock-absorbing effect for the vehicle.
SUMMARY OF THE PRESENT INVENTION
The present invention has a main object to provide a shock-absorbing safety wheel for motorized vehicles which provides a shock-absorbing device in the rim to improve the shock-absorbing effect for a motorized vehicle.
Another object of the present invention is to provide a shock-absorbing safety wheel for motorized vehicle in which the tire is solid without inflation so that the user need not carry a spare tire.
Further object of the present invention is to provide a shock-absorbing safety wheel for motorized vehicles which is easy to assemble.
The present invention will become more fully understood by reference to the following detailed description thereof when read in conjunction with the attached drawings.
