Abstract

The utility model provides a miniature axle wheel rim structure which belongs to the field of automobile driving axle assembly. The utility model aims at providing a miniature axle wheel rim structure which adopts a bearing block structure for positioning and compressing a bearing, and adopts a sealing system with the matching of internal and external double oil seals and an oil thrower. In the utility model, the oil thrower is arranged on a flange of a semi-axle, one end of the oil thrower is lap-jointed on the internal oil seal, the bearing is sheathed on the semi-axle, an outer ring of the bearing is fixedly connected with a bearing block, the internal oil seal is clamped between the bearing block and the semi-axle, an inner ring of the bearing is clamped with a positioning ring through a bearing check ring, the positioning ring is clamped by a gear ring, the bearing block is connected with a spindle head, and the external oil seal is clamped between the spindle head and the positioning ring. The utility model provides a novel design scheme of a miniature axle wheel rim part: the bearing block structure is adopted for positioning and compressing the bearing, and improving convenience in assembling and disassembling; and the sealing system with the matching of the internal and external double oil seals and the oil thrower is adopted for sealing lubricating oil.

Description

Miniature vehicle bridge wheel limit structure

Technical field

The utility model belongs to automobile drive axle assembly field.

Background technology

At present, most miniature vehicle bridge are taken turns the limit part and are all taked following structural shape:

1, takes pressure plate structure that axle bearing is compressed, and play oil removal, dust-separation effect;

2, the axle bearing inboard takes single oil sealing that gear reducer lube is sealed, and enters wheel limit part to prevent lubricating oil.

Above structural shape causes easily:

1, axle bearing compresses not firmly, and bearing life reduces;

2, seal oil is bad, and oil seepage phenomena appears in wheel limit part, and severe patient causes lubricating oil to enter drg, causes braking failure;

3, wheel limit part dismounting difficulty is not easy to maintenance, especially when parts such as replacing main reduction gear gear, because the caused damage parts possibility of dismounting semiaxis assembly is bigger.

The utility model content

The purpose of this utility model is to take bearing block structure that bearing is positioned and compresses, and takes match with the lubricating disc miniature vehicle bridge of sealing system of inside and outside double oil seal to take turns the limit structure.

The utility model is equipped with lubricating disc on the flange of semiaxis, lubricating disc one end is overlapped on the inner oil seal, bearing carrier ring is on semiaxis, outside race is captiveed joint with bearing seat, inner oil seal is stuck between bearing seat and the semiaxis, and bearing inner ring is by end ring and nest clamping, gear ring clamping nest, bearing seat is connected with spindle nose, and card has outer oil seal between spindle nose and nest.

The utility model has the O RunddichtringO at bearing seat and spindle nose junction.

The utility model provides the miniature vehicle bridge wheel of a kind of brand new limit partial design scheme: take bearing block structure that bearing is positioned and compresses, improve easy accessibility simultaneously; The sealing system of taking inside and outside double oil seal to match with lubricating disc is lubricated oil packing.

It is firm that the utility model has realized that fully axle bearing compresses, wheel limit part convenient disassembly (especially being convenient to the maintenance of main reduction gear part exchanging), seal oil good (having avoided because the misfunctioning of brake that oil seepage causes) has embodied the design progressive, and has been easy to realize.

Description of drawings

Fig. 1 is the utility model structural representation.

The specific embodiment

The utility model is equipped with lubricating disc 2 on the flange 1 of semiaxis 12, lubricating disc 2 one ends are overlapped on the inner oil seal 3, bearing 5 is enclosed within on the semiaxis 12, captive joint with bearing seat 6 in bearing 5 outer rings, inner oil seal 3 is stuck between bearing seat 6 and the semiaxis 12, and bearing 5 inner rings are by end ring 4 and nest 8 clampings, gear ring 9 clamping nests 8, bearing seat 6 is connected with spindle nose 11, and 8 cards of spindle nose 11 and nest have outer oil seal 10.

The utility model has O RunddichtringO 7 at bearing seat 6 and spindle nose 11 junctions.

The utility model bearing seat effectively compresses the outer ring of axle bearing, has realized that compressing of axle bearing is reliable; Adopt bearing block structure, the semiaxis assembly integral can be disassembled, made things convenient for the maintenance and the part exchanging of main reduction gear by dismounting bearing seat tie bolt and nut.Semiaxis inner oil seal, semiaxis outer oil seal, and lubricating disc form sealing system, double oil seal effectively improves sealing property, simultaneously, in particular cases in case oil seepage occurs, lubricating oil also can flow into lubricating disc along the rubber Oil Guide lip of outer oil seal, and oil throw away along Pan Bi, avoid drg is impacted.This scheme has solved fundamentally that little axle shaft pressure-bearing is tightly not firm, seepage is oily and problem such as dismounting maintenance difficult, innovation bearing block structure and double oil seal sealing system have been adopted first, all belong to innovation in the middle of reaching external little vehicle bridge product at home, shown technology neck property.
