Abstract
The utility model relates to a rim structural steel structure. The utility model is characterized in that an arc-shaped boss is added on the non tyre contact surface of the turning connecting point between an arc-shaped leg (1) of an original vehicle wheel rim and a bead seat (2); the rim body of a blocking head outside an arc-shaped lock ring groove (3) is widened; the end faces of both sides of the blocking head are vertical faces and are connected with an upper and a lower faces in a circular arc mode. One trapezoidal lock ring groove (4) is added on the left of the arc-shaped lock ring groove (3), which enlarges the general width of the lock ring groove of the rim. The contact surface (5) of the rim and a spoke is enlarged at the lock ring groove position; the radius of the circular arc of the upper arc-shaped position of the arc-shaped leg of the rim is shortened; the left end part of the arc-shaped leg (1) forms an arc shape. Because an automotive rim is made of the utility model, the rim is difficult to deform, crack and explode in the process of the run of a wheel. The utility model can completely prevent the edge angle of the end surface of the arc-shaped leg of the rim from pricking or cutting a tyre with outward extension. A retaining ring assembled on the lock ring groove of the rim is difficult to fly out of the rim.
Description
Technical field
The utility model relates to a kind of wheel rim formed steel construction.
Background technology
Tradition 7.00 wheel rim shaped steel are turn round rim hase thin thickness of junction of arcuate leg and arcuate leg and bead seat, and the arcuate leg end face is for facing directly; Thin and the inclination inwards of the outside shelves head of gutter; The position of matching with back-up ring has only an arc gutter and groove width narrow; The contact surface that wheel rim matches with spoke is narrow.Therefore, the rim for automobile wheel made from traditional 7.00 wheel rim shaped steel in power actuated vehicle carrying driving process, occurs crackle easily or bursts phenomenon at turn round junction and gutter position of arcuate leg, arcuate leg and bead seat; Secondly, when the tyre width that extends laterally when the tire pressurized exceeds the width of wheel rim arcuate leg, be prone to the damage of arcuate leg end face corner angle or cut tire.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned defective, a kind of fetalism 7.00 wheel rim shaped steel of strengthening and protect to be provided.
Scheme of the present utility model is: increased arc boss at the turn round non-tire contact surface of junction of the arcuate leg of former wheel rim shaped steel and bead seat; Gutter outside shelves head is widened, and a shelves both sides end face is vertical surface and is circular arc with top and bottom and is connected; Increased an echelon form gutter again on the right side of former arc shape gutter; Enlarged the contact surface that cooperates with spoke at former gutter position; Shortened the arc radius of the last arc part of arcuate leg, the arcuate leg end is an arc shape.
Advantage of the present utility model is: (1) arc boss is corresponding to have increased the turn round thickness of junction of rim hase shaped steel arcuate leg and bead seat, the also corresponding intensity that improves wheel rim; (2) rim for automobile wheel of making of Strengthen and Protect Tyre-Type Section Steel of Wheel Rim, in self-propelled vehicle carrying driving process, turn round junction and gutter position of arcuate leg and bead seat is not prone to crackle and bursts phenomenon.(3) right side, former arc gutter position has increased the echelon form gutter, is convenient to assemble the back-up ring of long bead seat, increases the longitudinal pressure of tire to the back-up ring bead seat, makes back-up ring be difficult for " flying " to come out from wheel rim; (4) rim for automobile wheel of making of Strengthen and Protect Tyre-Type Section Steel of Wheel Rim, because of it has enlarged the contact surface that matches with spoke, the corresponding intensity that improves rim hase makes wheel rim not yielding; Big and end is an arc shape because of the last arc part degree of being bent downwardly of its arcuate leg, therefore, can avoid the end face corner angle of wheel rim arcuate leg to stab and cut the tire that pressurized extends laterally fully.
Description of drawings
Fig. 1 is the cross-sectional view of utility model.
Among the figure, the 1st, arcuate leg; The 2nd, bead seat; The 3rd, the arc shape gutter; The 4th, the echelon form gutter; The 5th, the contact surface that gutter cooperates with spoke.
The specific embodiment
The utility model is to implement like this, and it is made up of arcuate leg (1), bead seat (2) and gutter (3), (4) four parts:
Embodiment 1: steel rolling mill makes heavier-duty earlier and protects tire 7.00 wheel rim shaped steel moulds, thereafter, utilizes hot rolling technology that billet rolling is become reinforcement and protects fetalism 7.00 wheel rim shaped steel.
Claims (2)
1, strengthens and protect fetalism 7.00 wheel rim shaped steel, comprise arcuate leg, bead seat and three positions of gutter, it is characterized in that: increased arc boss at the turn round non-tire contact surface of junction of the arcuate leg of wheel rim and bead seat; The outside shelves head of former gutter is widened, and a shelves two sides are vertical surface and are circular arc with top and bottom and are connected; Increase a gutter, strengthened the overall width of rim lock ring groove; Increased the contact surface that wheel rim matches with spoke; Shortened the arc radius of the last arc part of wheel rim arcuate leg, the arcuate leg end is an arc shape.
2, reinforcement according to claim 1 and protect fetalism 7.00 wheel rim shaped steel is characterized in that: the bottom land profile of bead seat can be set at how much lines such as " camber line+oblique line ", " camber line+straight line ", " camber line+camber line ".
