Abstract

The utility model discloses a rim reinforcing wheel. The rim reinforcing wheel comprises a rim, wherein the two ends of the rim comprise bent rim parts; tail ends of the external sides of each rim part extend in a direction opposite to the bending direction to form an extending part; and the rim part and the extending part form a horizontal S-shaped structure. Because the design of the extending part equivalently increases the width of the rim; and the rim obtains stronger anti-bending capacity by using the S-shaped structure; and the rim part can bear greater load and cannot be easy to deform when the wheel is in use.

Description

A kind of wheel rim is strengthened wheel

Technical field

The utility model relates to a kind of wheel, relates in particular to a kind of card, passenger vehicle or the small passenger car shape structure with tubeless tire rim.

Background technology

Wheels of automobile generally is divided into has inner tube of a tyre wheel and inner tube-free wheel two big classes, and wheel is made up of wheel rim and spoke, and the wheel rim appearance is equipped with tire, and spoke and wheel rim are welded together, and spoke relies on bolted connection to arrive with axletree.Inner tube-free wheel is compared with inner tube of a tyre wheel is arranged; Because advantages such as it is energy-conservation, safe have reached more than 95% in American-European countries's popularity rate; Rapid growth along with China's economy; The increase year by year of express highway path mileage, inner tube-free wheel has inner tube of a tyre wheel with annual about 30% speed in replacement in China recent years.Along with a large amount of uses of inner tube-free wheel, but its some weakness also come out, because the wheel rim ratio of tubeless tire rim has inner tube of a tyre wheel rim low; Width is narrower, so its flexural strength is lower, like this at turn inside diameter or meet slightly under the big slightly situation; The power that passes to wheel rim owing to tire is very big, just is easy to cause the distortion of wheel rim, causes situation such as wheel is out of shape, loses heart to happen occasionally after the wheel rim distortion; User's complaint brings certain difficult problem for the use of inner tube-free wheel.

Summary of the invention

The utility model purpose is exactly to the difficult problem of above mounting or dismounting tire, and a kind of wide basic inner tube-free wheel structure after improving is provided.

For realizing above purpose, the technical scheme below the utility model has been taked:

A kind of wheel rim is strengthened wheel; Comprise wheel rim; Said wheel rim two ends comprise sweeping rim section, and said rim section outside end is bent to form extendible portion to the direction extension opposite with its bending direction, and said rim section and extendible portion form the S shape structure of level.

The joining place of said rim section and extendible portion is 180 °.

The utility model compared with prior art has following advantage:

Increased the width of wheel rim, wheel rim part potential energy in use stands bigger load and not yielding, has ensured driving safety, the generation of situation such as reduced wheel rim distortion and wheel distortion of causing under big pressure condition simultaneously greatly, lose heart.

Description of reference numerals: 1-rim section, 2-bead seat, 3-deep trouth, 4-valve port, 5-extendible portion.

The specific embodiment

Explain further details below in conjunction with accompanying drawing and the specific embodiment content to the utility model.

Accompanying drawing 1 is original rim for automobile wheel section structure scheme drawing.

Accompanying drawing 2 is the utility model rim for automobile wheel cross-section structure; The section form of rim for automobile wheel is a drum type structure; The protruding sweep in these wheel rim two ends is a rim section 1; The middle part is a deep trouth 3, and the oblique line that rim section 1 is connected with deep trouth 3 is bead seat 2 partly, on the sidewall of deep trouth 3, is provided with valve port 4; Outside end in two wheel rim parts 1 is bent to form extendible portion 5 to the direction extension opposite with its bending direction respectively, and said rim section 1 and extendible portion 5 form the S shape structure of a level.

Further, this extendible portion 5 is 180 ° with the joining place of rim section 1.Because the design of this extendible portion 5 is equivalent to increase the wheel rim width, the structure of S type makes the counter-bending ability of wheel rim stronger, and wheel rim part potential energy in use stands bigger load and not yielding.

This wheel rim adopts existing inner tube free wheel rim roll extrusion manufacturing approach, utilizes the wheel rim of this structure roll forming machine, roll die to create, and its sectional curve physical dimension meets the YB/T5227 relevant criterion.

Above-listed detailed description is to the specifying of the utility model possible embodiments, and this embodiment is not the claim in order to restriction the utility model, does not allly break away from the equivalence that the utility model does and implements or change, all should be contained in the claim of this case.

Claims (2)

1. a wheel rim is strengthened wheel; Comprise wheel rim; Said wheel rim two ends comprise sweeping rim section; It is characterized in that: said rim section outside end is bent to form extendible portion to the direction extension opposite with its bending direction, and said rim section and extendible portion form the S shape structure of level.

2. a kind of wheel rim as claimed in claim 1 is strengthened wheel, and it is characterized in that: the joining place of said rim section and extendible portion is 180 °.
