Abstract

The utility model discloses a high strength integrated seat retaining ring, which consists of a rim body, a retaining ring A, a retaining ring B, a seat ring, a lock ring and a rear segment, wherein the rim body is welded with the rear segment into one body. The high strength integrated seat retaining ring is characterized in that the retaining ring A and the rear segment adopt integrated design to form an integrated retaining ring rear segment; the retaining ring B and the seat ring adopt integrated design to form an integrated retaining ring seat; a convex block arranged on the lock ring is matched with a concave block on the rim body to play a role of fixing the retaining ring seat; both walls of the retaining ring A and the retaining ring B are subjected to thickening processing; when a tyre is arranged into a rim and is stressed with the maximum force, friction cannot be generated among components and the positions of the retaining rings and the seat ring cannot generate relative displacement so as to avoid the problem that occlusion of two components caused by long-term operation forms wear and occlusion gash of the seat ring and prolong the service life of the rim. The high strength integrated seat retaining ring has the advantages of simple structure, cost saving, capability of effectively strengthening strength of the rim and prolonging the service life of the rim and the like and has great popularization value in the automotive field.

Description

High-strength integral retainer seat ring

Technical field:

The utility model relates to a kind of wheel component of large-scale goods carrying vehicle, relates in particular to a kind ofly can strengthen the wheel rim intensity, prolong the wheel rim high-strength integral retainer seat ring in service life.

Background technology:

Tire is installed on the wheel rim usually, can support vehicle body, the buffering foreign impacts, realize contacting and guaranteeing the rideability of vehicle with ground-surface, tire is everlasting complicated and exacting terms uses down, it is bearing various distortion, load, power effect in motion, and wheel is made up of tire, wheel rim, and mounting of tyre is on wheel rim.At present, the rim for automobile wheel that most of Oversize vehicles use, as shown in Figure 1, rim hase 1 is welded as a whole with back segment 6, and back segment 6 is provided with step with seat ring 4 one ends, is

Shape, back-up ring A2 is placed on the back segment 6, seat ring 4 is inserted in rim hase 1, back-up ring B3 is placed on the seat ring 4, be subjected to the outside thrust pressure of tire 7, back-up ring A2, back-up ring B3 form and cooperate with back segment 6, seat ring 4 respectively, the projection and the rim hase 1 fovea superior piece that are provided with on the retainer 5 cooperatively interact, to 4 fixations of mounted seat ring, because of back-up ring A2, back-up ring B3 are placed on respectively on back segment 6, the seat ring 4, adopt split-type structural, can produce friction between long-play back-up ring and back segment, the seat ring, reduce the service life of rim for automobile wheel; In addition, because existing back-up ring is very thin, as shown in Figure 2, when conventional rim when running to maximum weighted, back-up ring B3 deforms under the big load forces effect of tire easily, and when distortion downwards took place back-up ring B3, the position of back-up ring B3 and seat ring 4 can produce relative displacement; As shown in Figure 3, when the heavy-load type wheel rim when running to maximum weighted, taper fitting place D point has the gap of 3mm between back-up ring and the seat ring, because wheel rim seat ring and back-up ring are to adopt 20 degree conical surface interference fit, be that pack into back-up ring behind the seat ring of back-up ring is subjected to the pushing of tire, to move axially 4.5mm to the big end of cone, form two part interference fit, any point all will be interference fit into stressed rear cone from the conical surface and produce the gap on the wheel when wheel moves, because wheel is continuously to turn round, forms two parts like this and produces relative displacement, in long running, cause two part interlocks, form seat ring mill and the damage gash that bites, shorten service life greatly; Shown in Figure 4, when the heavy wheel rim of another kind (is not have step to stop on the seat ring, back-up ring is subjected to outside thrust pressure of tire and seat ring interference fit) when running to maximum weighted, because wheel rim seat ring and back-up ring are to adopt 20 degree conical surface interference fit, be that pack into back-up ring behind the seat ring of back-up ring is subjected to the pushing of tire, to move axially to the big end of cone, owing to do not have step to stop on the seat ring, form two parts very big interference fit is arranged, but when the wheel continuous rotation because the distortion of two part stress is different, form two parts and produce relative displacemenies, cause two part interlocks, form seat ring mill and the damage gash that bites in running for a long time, serious meeting causes the back-up ring fracture, shorten service life greatly, brings potential safety hazard in travelling, problems such as harm personal safety.

The utility model content:

The utility model is at the deficiencies in the prior art, provides a kind of and can strengthen the wheel rim intensity, prolonged the wheel rim high-strength integral retainer seat ring in service life.

Realize above purpose, the technical solution adopted in the utility model is as follows:

High-strength integral retainer seat ring is made up of rim hase, back-up ring A, back-up ring B, seat ring, retainer, back segment; Wherein rim hase and back segment are welded as a whole, and it is characterized in that: back-up ring A and back segment are the integrated design, and form one back-up ring back segment; Back-up ring B and seat ring are the integrated design, and form one back-up ring seat; Projection that is provided with on the retainer and rim hase fovea superior piece cooperatively interact, and the back-up ring seat is played fixation.

Described back-up ring A, back-up ring B two walls adopt thickening to handle, and increase the load forces to tire.

Described back segment one end is provided with a protruding block, increases the holding capacity of back-up ring A, has effectively improved stressed cross-sectional plane.

The utility model compared with prior art, have the following advantages: (1) since back-up ring A and back segment be the integrated design, back-up ring B and seat ring are the integrated design, stressed when maximum when the tire wheel rim of packing into, can not produce friction between each parts, the position of back-up ring and seat ring can not produce relative displacement, thereby avoided long running, cause two part interlocks, form seat ring mill and the damage gash that bites, prolonged the service life of wheel rim; (2) because back-up ring A, back-up ring B two walls adopt thickening to handle, make back-up ring be not easy to deform in the big load forces effect of tire, prolonged the service life of wheel rim equally, increased the driving safety of driving; (3) back segment one end is provided with a protruding block, increases the holding capacity of back-up ring A, has effectively improved stressed cross-sectional plane.
