Abstract

The utility model relates to a high-strength dust-proofing wheel, pertaining to a dedicated wheel for a jinrikisha. Two primary spokes (2) are arranged between a high-strength rim (1) and an outwards-turned side-wheel core retainer plate (11) along the circumference. V-shaped secondary spokes (3) are positioned on the protruding ribs of the high-strength rim positioned between the medial surface of two primary spokes (2) and two primary spokes, forming a high-strength wheel. A small axis of a hollow step axle (9) is provided with an adjustable inner retainer ring (10), an inner bearing (8) and an outer bearing (15). A spacer sleeve is arranged between the inner and outer bearings. A plunger ring (12) is fastened on the outer bearing (15) with a socket head screw (14) and a washer (13). The outwards-turned side-wheel core retainer plate (11) is provided with a lubricating nipple (5), an inner dust-proofing cover (7) and an outer dust-proofing cover (4). The utility model has the advantages of novel design, unique structure, high strength, big bearing capacity, good dust-proofing function, well-lubricated feature, convenient maintenance and long service life, suitable for the jinrikisha.

Description

The high strength wheel that prevents dust

Technical field: the utility model relates to the manpower wheel, particularly a kind of high strength wheel that prevents dust,

Background technology: the wheel of human powered vehicle of prior art generally is formed by connecting with deformed steel bar spoke and steel bar nut by common rim and special-purpose wheel core housing, or is formed by common rim and Y font spoke and common wheel core housing assembly welding.The wheel of the various structures of prior art has all that bearing capacity is poor, spoke is easily broken and Wheel bearing poor lubrication, not antisoiling shortcoming.

Summary of the invention: the purpose of this utility model is to provide a kind of high strength wheel that prevents dust, this car wheel structure novelty, practical, have intensity height, bearing capacity big, prevent dust, lubricated good and characteristics easy to maintenance, can reach the purpose that in-use performance is good and the life-span is grown.

Formation of the present utility model: form by high strength rim, the main wheel width of cloth, the jockey pulley width of cloth, flanging wheel core housing, oil nozzle, spacer, interior dust boot, neck bearing, hollow step axletree, adjustable inner shield ring, trim ring, bullet pad, socket head cap screw, outer bearing, outer dust boot, along the circumferential direction uniform main wheel 2 between high strength rim 1 and flanging wheel core housing 11, in that V-arrangement jockey pulley 3 is installed on the medial surface of two main wheels 2 and on the high strength rim inner face between two main wheel width of cloth, form the high strength wheel; On the little axle of hollow step axletree 9, adjustable inner shield ring 10, neck bearing 8, outer bearing 15 are installed, suit spacer 6 between the interior outer bearing, by socket head cap screw 14 and bullet pad 13 trim ring 12 is pressed on the outer bearing 15 dust boot 4 outside installation oil nozzle 5 and interior dust boot 7 reach on flanging wheel core housing 11 at axle head.

An inside circle convex tendon is arranged in the middle of the high strength rim 1, and 2,16 C shape jockey pulleys of 8 S shape main wheels 3 cooperate welding with convex tendon.

Toroidal is outwards translated at two of flanging wheel core housing 11, the middle interior dust boot 7 with holes of suit on the inside trumpet mouth, the outer dust boot 4 of suit hat on the exit skirt outside.

Compared with the prior art, the utility model has following characteristics:

1. by the high strength rim, 8 S shape main wheel width of cloth, 16 C shape jockey pulley width of cloth become the high strength wheel with flanging wheel core housing assembly welding:

2. by outer dust boot, interior dust boot and oil nozzle are assembled into dustproof, the lubrication sealing structure of Wheel bearing, guarantee that Wheel bearing is preventing dust and lubricating under all good condition and work;

3. adjustable inner shield ring by the gauge adjustment, can guarantee the assembly quality of Wheel bearing when assembling;

4. axle head is fixed bearing arrangement, makes the maintenance dismounting extremely convenient.

Description of drawings: Fig. 1 is the utility model structural representation; Fig. 2 is the A-A cutaway view of Fig. 1; Fig. 3 is the B-B cutaway view of Fig. 1; Fig. 4 is the C-C cutaway view of Fig. 1.。

1. high strength rims among the figure, the 2. main wheel width of cloth, the 3. jockey pulley width of cloth, 4. outer dust boot, 5. oil nozzle, 6. spacer, 7. in dust boot, 8. neck bearing, 9. hollow step axletree, 10. adjustable inner shield ring, 11. the flanging wheel core housing, 12. trim rings, 13. bullet pads, 14. socket head cap screws, 15. outer bearings.

The specific embodiment: as Fig. 1, shown in Figure 2, at first high strength rim 1,8 S shape main wheels 2,16 C shape jockey pulleys 3 and flange wheel core housing 11 are made and are shaped, then the uniform arrangement of R mouth one end of opening of 8 S shape main wheels 2 is welded on the convex tendon of high strength rim 1, the uniform arrangement of butt end of 8 S shape main wheel width of cloth is welded on the flanging wheel core housing 11, again 16 C shape jockey pulley width of cloth are pressed two one group, mode with convex surface back of the body convex surface is formed 8 groups of v-shaped structures, again the summit of 8 groups of v-shaped structures is welded in respectively on the mid point of rim between two S shape main wheel width of cloth, the bipod of 8 groups of v-shaped structures is welded in respectively on the both sides of 8 S shape main wheel width of cloth, thereby constitute the high strength wheel, earlier interior dust boot 7 is sleeved on the hollow step axletree 9 during assembling, choose the thickness of adjustable inner shield ring 10 then, the order of the high strength wheel → outer bearing 15 → trim ring 12 → bullet pad 13 → socket head cap screw 14 that constitutes by adjustable inner shield ring 10 → neck bearing 8 → spacer 6 → flanging wheel core housing 11 assembly weldings is loaded onto and socket head cap screw 14 is screwed, with manual preliminary operation wheel light normal after, oil nozzle 5 is installed at middle part at flanging wheel core housing 11, and with oil gun filling with grease between two bearings in the flanging wheel core housing, at last outer dust boot 4 is loaded onto, be seated being unkitted the interior dust boot 7 that puts in place simultaneously, its inside and outside dust boot all is stuck on flanging wheel core housing 11 flange.

As shown in Figure 3, main wheel 2 is S shapes.

As shown in Figure 4, jockey pulley 3 is C shapes.

During use, at first on high strength rim 1, load onto tire, solid tyre or qi of chong channel ascending adversely tire all can, then hollow step axletree 9 is contained on the vehicle frame of power car and can uses.
