Abstract
The utility model particularly relates to the support and structural technology of a left half axle and a right half axle in a light automobile rear driving axle assembly, as well as a brake assembly part. In order to solve the technical problems that the supporting structure of a uniserial deep groove ball bearing has bad anti-impact load capacity and severe abrasion in the light automobile rear driving axle assembly, the utility model provides the technical proposal of a light automobile rear driving axle assembly with a reinforced supporting structure. In the technical proposal, the brake parts of the brake assembly part are supported and arranged on the left half axle and the right half axles through a biserial taper roller bearing and a bearing pedestal thereof in a transmission manner; and a waterproof oil seal is pressed and arranged at the port of the bearing pedestal at the outer end of the biserial taper roller bearing. The utility model has the advantages that the anti-impact load capacity is strong, and the traveling safety of the light automobile and the passing ability are obviously improved.
Description
Technical field
The utility model relates to automobile rear driving axle assembly technology, in particular the left and right half of lilliput car rear driving axle assembly and drg component support structure technical field.
Background technology
Lilliput car rear driving axle assembly is the critical component in the lilliput car transmission system, and its agent structure includes main reduction gear and several parts such as diff, left and right half and drg component and axle housing etc. are formed.In prior art constructions constitutes, left and right half is as the rigid shaft spare that transmits engine output torque, be through single-groove grooved ball-bearing casing and bearing seat thereof and drg, the fastening assembling of axle housing end axle tube, constitute supporting construction, the fastening installation brake wheel in left and right half outer end, and drive its rotation, engine output torque is transmitted two side drive wheels.Now, increasing lilliput car is runed widely on the traffic route of each grade, because bad road surface is to the impact load increasing of rear driving axle assembly, in the supporting construction of lilliput car driving rear axle assembly, its single-groove grooved ball-bearing casing of impact load effect, its aggravation of wearing and tearing; In addition, the paddle increase greatly of probability of automobile, outer distolateral the anti-dust seal that is provided with function singleness of bearing in the lubricating grease, reduced the bearing lubrication effect in the water maceration bearing, and its wearing and tearing are more strengthened, and endurance degree and normal operation life obviously shorten.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of actv. to improve the heavier-duty supporting construction lilliput car rear driving axle assembly of lilliput car rear driving axle resistance to shock loads ability.The heavier-duty supporting construction lilliput car rear driving axle assembly technical scheme that the utility model provides, its major technique content is: a kind of heavier-duty supporting construction lilliput car rear driving axle assembly, include main reduction gear and diff, the drg component, be arranged between the two a left side with transmission, right axle shaft and axle housing thereof are formed jointly, the part brake of drg component is arranged at a left side through double-row conical bearing and bearing seat rotational support thereof, on the right axle shaft, the outer distolateral bearing seat port of double-row conical bearing press-fits the waterproof oil sealing is set, and the brake wheel and the part brake that are fixedly installed in semiaxis outer end tie-plate constitute the drg component jointly.
The disclosed heavier-duty supporting construction of the utility model lilliput car rear driving axle assembly technical scheme, by a left side, double-row conical bearing on the right axle shaft and bearing seat thereof support drg and axle housing are set, the outstanding technique effect that this rotational support structure has is: double-row conical bearing is the supporting construction form of main body, back-to-back biserial structure of this bearing and roller liner adjustable axle thereof have been made full use of to the strong characteristic of the non-maintaining and capacity of resisting impact load of play, thereby effectively improve the impact resistance of this supporting construction, solved lilliput car in technical matters that bad road traveling caused strengthens rear driving axle assembly impact load, guarantee the driving safety of lilliput car, can obviously prolong bearing service life.In addition, combine the setting of supporting dubbin seal structure with double-row conical bearing, paddle and avoided in travelling further having guaranteed the reliability of this bearing in the grease in the water maceration bearing, improved the through performance of lilliput car.
Description of drawings
Fig. 1 is the general assembly sectional structure chart of heavier-duty supporting construction lilliput car rear driving axle assembly of the present utility model
Fig. 2 is the drg component of Fig. 1 and the sectional structure enlarged drawing of semiaxis assembled part.
The specific embodiment
The disclosed heavier-duty supporting construction of the utility model lilliput car rear driving axle assembly, its concrete structure constitutes as shown in Figure 1 and Figure 2, its main body formation includes main reduction gear and diff 1, and left and right half 2 and axle housing thereof and two-semiaxle axle head stack-mounted drg 3 components constitute jointly.Hold from outside to inside, be respectively equipped with outer end tie-plate 13, waterproof oil sealing platform, bearing stand, snap ring mounting groove, axle-shaft oil seal platform, inner castellated shaft on the left and right half, double-row conical bearing 4 and bearing seat 5 thereof are on the fastening bearing stand that is arranged at left and right half 2 of bearing interstage sleeve 6 and snap ring 7, press-fit in waterproof oil sealing platform in outer distolateral bearing seat 5 external port of double-row conical bearing 4 and be provided with waterproof oil sealing 8, in the axle tube 9 of axle housing outer end, the axle-shaft oil seal platform place that is installed in semiaxis is provided with axle-shaft oil seal 10; The seat stand both sides that drg 11 and axle tube 9 are positioned at bearing seat 5 are provided with through bolt, nut and bearing seat 5 fixed installations, brake wheel 12 is fixedly installed by wheel hub bolt and nut and is installed on the semiaxis outer end tie-plate 13, constitutes this heavier-duty supporting construction lilliput car rear driving axle assembly jointly.
Claims (1)
1, a kind of heavier-duty supporting construction lilliput car rear driving axle assembly, include main reduction gear and diff, drg component, form jointly with left and right half and axle housing thereof that transmission is arranged between the two, the part brake that it is characterized in that the drg component is arranged on the left and right half through double-row conical bearing (4) and bearing seat rotational support thereof, outer distolateral bearing seat (5) port of double-row conical bearing press-fits waterproof oil sealing (8) is set, and the brake wheel and the part brake that are fixedly installed in semiaxis outer end tie-plate constitute the drg component jointly.
