Abstract
The utility model relates to a wheel rim with a circular ring, a seating ring or a lock ring which are provided with dismountable edges, in particular to a multi-piece reinforced wheel rim comprising a wheel-rim body and a retainer ring. The wheel-rim body is provided with a lock-ring groove which forms a bending segment by bending upwards, and the bending segment is provided with the top of the lock-ring groove; the bottom of the retainer ring is provided with a supporting part which is connected with the wheel-rim body in manner of supporting. The structural feature of the utility model is that: the supporting part is supported in the lock-ring groove; the retainer ring is arranged in the lock-ring groove in manner of supporting through the supporting part at the bottom of the retainer ring, and the acting force of the retainer ring on the wheel rim completely acts on the lock-ring groove; thus the acting force on the bending segment is reduced, and the lock-ring groove of the wheel rim is not apt to fracture at the bending point; the multi-piece reinforced wheel rim has increased strength and long service life.
Description
Technical field
The utility model relates to a kind of wheel rim with detachable flange ring, seat ring or lock ring, and particularly a kind of multi-piece type is strengthened wheel rim.
Technical background
Wheel rim of the prior art comprises that the one piece rim of back-up ring and rim hase Construction integration and back-up ring and rim hase divide the multi-piece rim of body structure, and this back-up ring had both comprised that the circlip of Construction integration also comprised the compound type back-up ring of branch body structure.A kind of multi-piece rim of the prior art as shown in Figure 1, it comprises rim hase 1 and back-up ring 2, has gutter 11 on the rim hase 1, gutter 11 upwards is bent to form bending segment 12, bending segment 12 has locked groove top 13, and when back-up ring was installed on the gutter, back-up ring had the support portion 3 with gutter 1 support and connection, this support portion is supported on gutter and gutter top simultaneously, and is a kind of stepped appearance.But, when back-up ring is supported on the top of gutter and gutter, when the masterpiece of tire is used on the back-up ring, top at gutter also has the power effect, this power is decomposed into horizontal direction and vertical direction, and vertical forces can be approximated to be zero to the moment of bending place, and horizontal direction power is the amassing of length of power and gutter top to bending place to the moment of bending place, thereby this horizontal direction power is bigger to the moment of the bending place of gutter, makes gutter very easily at rupture.
Summary of the invention
The gutter that technical problem to be solved in the utility model is to provide a kind of wheel rim is easy fracture not in the bending place, and the multi-piece type that intensity is big is strengthened wheel rim.
The purpose of this utility model realizes by following approach.
Multi-piece type is strengthened wheel rim, comprises rim hase and back-up ring, and rim hase has gutter, gutter upwards is bent to form bending segment, bending segment has the gutter top, and the bottom of back-up ring has the support portion with the rim hase support and connection, and its structural feature is: the support portion is supported in the gutter.
Like this, the support portion support of back-up ring by its bottom is installed in the gutter, the power that tire acts on the back-up ring directly acts on the gutter by this support portion, the distance of the commentaries on classics corner between the point of action of this power and gutter and the bending segment is less, and the moment of generation is also just less, and back-up ring does not have the effect of power to bending segment, therefore rim hase reduces at the stressed of bending place of gutter, easy fracture not, intensity increases, and prolongs the service life of wheel rim.
Structure of the present utility model can be specially.
The support portion is supported in the commentaries on classics corner between gutter and the bending segment.
Like this, back-up ring only is supported on the rim hase by this support portion, back-up ring acts on the rim hase by this support portion the application force of rim hase, and this support portion acts directly on the commentaries on classics corner, thereby back-up ring can be similar to crossing the power at the center, angle of turning the application force of rim hase, this power also is approximately zero to the moment at center, turning angle, therefore, what the rim hase on turn was suffered is that the moment of the clockwise bending in the center of circle can be approximated to be zero with center, turning angle, the stressed of bending segment reduces greatly, rim hase is changeing corner intensity enhancing, not easy fracture.Simultaneously, when back-up ring is supported on commentaries on classics corner between gutter and the bending segment by this support portion, bending segment not only has the supporting role of vertical direction to back-up ring, and bending segment also has the effect to back-up ring containing in the horizontal direction, and the installation site of back-up ring is limited within the bending segment.
The profile of the commentaries on classics corner between the profile on top, support portion and gutter and the bending segment coincide.
The top of support portion leans in gutter, and the profile of the commentaries on classics corner between the profile on top, support portion and gutter and the bending segment coincide, thereby makes its installation more firm.
Support portion or extend in the same way and be supported in the gutter along the direction of directly hold with back-up ring, perhaps the edge favours this and directly holds and be arranged in the direction extension of the same side and be supported in gutter with the arc end of back-up ring.
Back-up ring has arc end and straight end, and straight end is divided into and gutter bonded assembly part, the extension of support portion or this straight end parts and being installed on the gutter; Perhaps the support portion is for to be divided into inclination with this straight end, and is positioned at the same side with the arc end of back-up ring.Like this, for the wheel rim of various different models because the difference of the shape of its gutter, thereby can select the support portion of different shapes.The gutter bending segment bends straight up, and gutter exposes fully, thus a kind of support portion of shape before can using; The gutter bending segment upwards bends and slopes inwardly, and the gutter part is covered below bending segment, thereby can use the bevelled support portion, and this support portion is just in time cooperated with the gutter of this shape.
Because back-up ring supports by its support portion and is installed in the gutter, back-up ring only has the effect of power to gutter, and masterpiece useless is used for the bending segment place, therefore, for alleviating the weight of wheel rim, saving in material, the structure of wheel rim can be done following improvement.
Bending segment reduces to the thickness at gutter top gradually from the bending place.
Because the support portion of back-up ring is directly supported and is installed in the gutter, thereby the stressed of bending segment reduced greatly, therefore, the thickness of this bending segment can be reduced, and, bending segment from the bending place to its stressed successively decreasing of top, thereby bending segment reduces to top thickness gradually from the bending place, can either guarantee that wheel rim has enough intensity, again can saving in material, alleviate the weight of wheel rim.
Being reduced to along the bending segment outside or with the oblique of straight line of bending segment thickness reduces, perhaps reducing with circular arc.
In sum, the utility model has the following advantages compared to existing technology: back-up ring supports by the support portion of its bottom and is installed in the gutter, its application force to rim hase acts in the gutter fully, thereby reduce application force to bending segment, the gutter that makes wheel rim is easy fracture not in the bending place, intensity enhancing, long service life.
