Abstract
The utility model discloses a wheel rim with reinforcing ribs and without an inner tire. The wheel rim comprises two wheel flange parts, a first bead seat close to a wheel spoke, a second bead seat far away from the wheel spoke, and a deep groove part, wherein one end of the first bead seat and one end of the second bead seat are connected with the two ends of the deep groove part respectively; the other end of the first bead seat and the other end of the second bead seat are connected with one end of each of the two wheel flange parts respectively; and a groove wall, which is close to the second bead seat, in the deep groove part is provided with a first reinforcing rib of which the inner wall surface is concave or convex relative to the groove wall of the deep groove part. The first reinforcing rib is favorable for reinforcing the second bead seat, and pulls the second bead seat and the deep groove part together when the second bead seat is subjected to circumferential pressure, so that the stress of the second bead seat and the deep groove part is effectively enhanced, and the second bead seat far away from the wheel spoke is prevented from being stressed and deformed.
Description
Technical field
The utility model relates to a kind of inner tube-free wheel wheel rim, particularly relates to a kind of inner tube-free wheel wheel rim that has reinforced rib.
Background technology
Wheel is to occupy the vitals that is used for transmitting rotary load and support load between vehicle bridge and the tire, generally is made of wheel rim and spoke, and wherein, spoke plays a part to be connected with vehicle bridge, and wheel rim plays fit a tyre.Wheel is divided into by the kind of adapted tire inner tube of a tyre wheel and inner tube-free wheel two big classes.Characteristics such as that inner tube-free wheel has is in light weight, energy-conserving and environment-protective and safety performance are good, thereby be substituted with inner tube of a tyre wheel gradually.Card, objective vehicle inner tube-free wheel have reached 100% at the Occupation coefficient in Europe, reach more than 90% in the U.S., also reach more than 85% in Japan.Increase along with China's rapid development of economy, express highway in nearest 2 years, and the energy-saving and emission-reduction task is great day by day, estimate through the time China card of 5-7, the inner tube freeization of passenger vehicle will reach 85% or more with 30% speed increment use every year of China's inner tube-free wheel again.Because rim for automobile wheel manufacturing process and the special factor of structure, make 15 ° of positions of two ends bead seat on the wheel rim be subjected to tensile stress and two stress of compression effort of tire, be stressed bigger position on the wheel rim.In use distance is installed the nearer end bead seat carrying of spoke better, and is not yielding, and apart from spoke other end bead seat far away because far away apart from spoke, do not have the support of spoke, its intensity can not satisfy operating needs preferably, very easily distortion.In addition, the bead seat far away apart from spoke at Ackermann steer angle also will bear side force, so this bead seat is stressed bigger, and it is more serious to damage phenomenon, and can cause phenomenons such as loss of tyre pressure, tread flaking after the bead seat distortion, thereby causes the accident easily.
