Description

Novel wheel rim

A kind of trac. wheel rim belongs to trac. running gear parts.

Existing trac., compact tractor front vehicle wheel wheel rim particularly, constitute by main wheel circle, guard ring, disc and wheel hub, guard ring is set in main wheel circle one end (disc outer rim), blocks guard ring by a reinforcing bar spring coil, makes it to be unlikely slippage, facts have proved, this wheel rim has following deficiency, and is during the dismounting tire, time-consuming; When giving inflation of tire, when particularly inflation is too sufficient, guard ring fracture, spring people, casualty accident often take place.

The present invention's purpose is for overcoming the defective of existing trac. front vehicle wheel wheel rim, a kind of tyre dismounting of both being convenient to is provided, guaranteeing new car rim of wheel safe in utilization again.

The scheme of taking is, novel wheel rim is made of wheel rim, disc and wheel hub, and described wheel rim is to be combined with outer ring (3) by inner ring (2) to form, and Internal and external cycle has symmetrical section; Inner ring (2) is cast into one with disc (4) and wheel hub (5).

The inside and outside circle of such scheme is by bolted connection, and not only the dismounting tire is convenient, and main is to avoid guard ring fracture casualty accident to take place.

This Figure of description provides an embodiment, wherein:

Accompanying drawing 1 is the utility model front view

Accompanying drawing 2 is the utility model A-A cutaway view

Novel wheel rim (1) comprised wheel rim that tire can be installed, supporting wheel rim disc, can with axle bonded assembly wheel hub three parts, wherein wheel rim is a coupling piece that is combined with outer ring (3) and constituted by inner ring (2), inside and outside circle has symmetrical section, the whole wheel rim section that is combined into is approximate " U " type, is convenient to install tire; Inner ring (2) is cast into integral piece with disc (4) and wheel hub (5), and connects outer ring (3) by bolt (6), and so-called outer ring is meant half wheel rim in the road wheel outside, near the inner ring that is called of tractor chassis side; For gaining in strength, inside and outside ring outer wall is radially established several deep floors (7) respectively, and present embodiment is established 5 floors, and 5 tie bolts adopt the HT150 iron casting.

The utility model is mainly as 12 horsepowers of small four-wheel tractor front vehicle wheel wheel rims.

Claims (2)

1, the novel wheel rim (1) that is connected and composed successively by wheel rim, disc, wheel hub is characterized in that, described wheel rim is an even part that is combined into by symmetrical inner ring of section form (2) and outer ring (3); Inner ring (2) is made as one with disc (4) and wheel hub (5).

2, according to the described novel wheel rim of claim 1, it is characterized in that wall radial distribution floor (7) outside the inside and outside circle.
