Abstract

The utility model provides an elastic retainer ring for wheels, which comprises an inner ring and an outer ring, wherein the inner ring extends into a gutter of wheel rims, the outer ring is clamped at outer side edge of a tire, the inner ring extends upwards along the outer ring; the thickness of a shaft neck is gradually reduced, and the shaft neck is a transition from the outer ring to the inner ring and starts from the beginning end of a large arc surface of the outer ring to the tail end thereof; the part of the inner ring, which extends into the gutter of the wheel rims, has a length of 14 to 15 mm; the distance between the beginning end and the tail end of the large arc surface of the outer ring supported at side edge of the tire is 31 to 33 mm. By using the elastic retainer ring, materials deformed in the production process right meet the requirements of products, and problems that openings of standard spindles are entangled, or the clearance exceeds the standard are avoided; and the elastic retainer ring can effectively prevents the problems that an inflating valve is blocked, a balancing block drops off, and the elastic retainer ring cuts the tire, reduces the strength of parts, spokes, rims and retainer rings with equal strength are matched, avoids excess functions, and simultaneously can reduce surplus amount of material and avoid waste.

Description

A kind of circlip of wheel

Technical field

The utility model relates to a kind of auto parts and components, especially a kind of circlip of automotive wheel.

Background technology

The circlip of automotive wheel is to cooperate with wheel rim tire is kept off at the rim for automobile wheel waist in the wheel set fitting process, assurance wheel in-use performance.There is following problem in existing circlip in production and use:

1) process is difficult to control in the production process, for guaranteeing the product in-use performance, during cover standard mandrel (the standard mandrel press the making of rim lock ring groove size), technological requirement is satisfied in opening and gap behind the technological requirement back-up ring sizing, and opening and the gap phenomenon that exceeds standard often appears in reality; Cause the part of production often need do over again or reprocess or part is scrapped, the productive costs height.Major cause is, material has distortion to cause in process of production, material is when volume circle and sizing, because of stressed afterbody is elongated about 2mm, cause when wheel set assembles, the back-up ring afterbody can not fall in the rim lock ring groove, causes opening and peripheral clearance when cooperating with the standard mandrel to exceed the standard of product;

2) Valve inside dog and balance block easily come off, and easily isolate tire during vehicle operating.Major cause is, back-up ring material standard great circle arc width is 25.4mm, and tire is revealed seldom outward in great circle arc position, assembling back, causes consequence: Valve inside dog and balance block do not throw into fully and come off easily, overload or air pressure is not enough, tire is crushed and exceeds the back-up ring height, causes and cuts tire;

3) part strength is excessive, causes the function surplus.

Summary of the invention

The utility model provides a kind of circlip, can satisfy the production technology and the wheel operating needs of product, and make the part lightweight, reduces production costs.

In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: a kind of circlip of wheel, form with the outer ring that is stuck in the tire outer side edges by the inner ring that stretches in the rim for automobile wheel gutter, inner ring extends upward along the outer ring, the great circle cambered surface top of outer ring and inner ring axle journal to the thickness of great circle cambered surface end of transition mutually reduce gradually, it is characterized in that: described inner ring stretches into the part in the rim lock ring groove, length is 14～15mm, and top and the distance between the end that the outer ring is supported on the great circle cambered surface of tire side are 31～33mm.

To improvement of the technical scheme: described inner ring stretches into the part in the rim lock ring groove, and length is 14.5mm, and top and the distance between the end that the outer ring is supported on the great circle cambered surface of tire side are 32mm.

To further improvement in the technical proposal: the great circle cambered surface top of described outer ring and the inner ring wall thickness of the axle journal of transition mutually are 8.8～7.7mm, and the wall thickness of great circle cambered surface end is 7.5～8.1mm.

Beneficial effect:

Use a kind of circlip described in the utility model, the circlip inner ring stretches into the part in the rim lock ring groove, be of a size of 14～15mm, can make material be out of shape the back in process of production, the problem that standard mandrel opening and gap exceed standard can not occur overlapping for just in time satisfying product requirement; Top and the distance between the end that the outer ring is supported on the great circle cambered surface of tire side are 31～33mm, and such width can effectively prevent the appearance of the problem that Valve inside dog and balance block easily come off, back-up ring cuts tire after assembling; The great circle cambered surface top of outer ring and the inner ring wall thickness of the axle journal of transition mutually are 8.8～7.7mm, the wall thickness of great circle cambered surface end is 7.5～8.1mm, the best cooperation of wheel spoke, wheel rim and back-up ring is an equal strength, reduced part strength, avoid causing the function surplus, simultaneously can reduce the material surplus capacity, avoid waste.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the cross section enlarged drawing at A-A of the present utility model place.

The specific embodiment

As Fig. 1, the utility model shown in Figure 2 is made up of with the outer ring 2 that is stuck in the tire outer side edges the inner ring 1 that stretches in the rim for automobile wheel gutter, inner ring 12 extends upward along the outer ring, the great circle cambered surface top of outer ring 2 and outer ring axle journal to the thickness of great circle cambered surface end of transition mutually reduce gradually, described inner ring 1 stretches into the part B in the rim lock ring groove, length is 14.5mm, top and the distance C between the end that outer ring 2 is supported on the great circle cambered surface of tire side are 32mm, the great circle cambered surface top of outer ring 2 and inner ring 1 the wall thickness D of the axle journal of transition mutually are 8.8～7.7mm, and the wall thickness E of great circle cambered surface end is 7.5～8.1mm.

Circlip is that 8.5 circlip materials are made in the present embodiment.

1. the circlip described in the present embodiment, maximum stress is 295Mpa, less than song clothes intensity 345Mpa, can satisfy the wheel strength requirement.

2. do 1,000,000 times by the GB5909-1995 standard, wheel is intact, and can satisfy product requirement fatigue life.

3. since the small lot test manufacture, shop characteristic is better, essentially noly does over again, reprocesses with part and scrap phenomenon because of what problem of materials caused, has reduced productive costs.

4. seldom occurring balance block, Valve inside dog in the wheel use easily comes off and cuts the tire problem.

Pts wt has alleviated 5.8%, and reduced cost about 120 ten thousand yuan for company every year.The automobile weight-saving requirement that fallen has enough improved the wheel market competitiveness.
