Description

Special semi-axis of heavy truck

Technical Field

The utility model relates to the technology of automobile half shafts, in particular to a special half shaft for a heavy truck.

Background

The vehicle needs to turn after walking, and the rotation of wheels on two sides is different, which requires that a differential gear is arranged on a transmission shaft. The differential is a device which enables wheels on two sides to rotate at different speeds, and the half shaft is a shaft which connects the differential with a driving wheel. The half shaft of the existing heavy truck is generally processed by adopting a cast steel material, air holes or white spots are easy to appear in the processing process, a turning tool is often damaged by turning, the rejection rate is increased, the half shaft is connected with a flange plate by using flat-head bolts, the flange plate bolts are easy to loosen due to the vibration impact of the heavy truck during driving, in order to solve the technical problems, scientific research units and technical personnel of production enterprises continuously explore and research, and hope to design the special half shaft for the heavy truck, although some progress is made in the technology, the technical problem which is not overcome still exists in the actual application.

Disclosure of Invention

The utility model aims to overcome the defects and provide the special half shaft for the heavy truck. The half shaft is reasonable in design and easy to process, can effectively prevent bolts from loosening, and can greatly improve the working durability. The split half shaft structure and the design that the groove is matched with the convex body are adopted, so that the half shaft can be rapidly welded in a tight fit manner, and the processing is simple; the flange plate adopts the counter bore design to can realize that the connection between hexagon socket head cap screw and the flange plate is inseparabler, prevent that the bolt from becoming flexible, can effectively prolong the life of semi-axis.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a special semi-axis of heavy truck, contains the semi-axis left side body, the recess, the semi-axis right side body, the convex body, the ring flange, the counter bore, first spline, the second spline, lead oil groove, the thimble hole, semi-axis left side body right-hand member is equipped with the recess, semi-axis right side body left end is equipped with the convex body identical with the recess, the edge part of ring flange is equipped with the counter bore, the right-hand member outside of semi-axis right side body is equipped with first spline, the second spline, be equipped with between first spline, the second spline and lead the oil groove, the top of the semi-axis left side body and the top of the semi-axis right side body are equipped with the thimble hole.

The technical principle adopted by the utility model for solving the technical problems is as follows: the half shaft of a heavy truck is generally processed by cast steel materials, air holes or white spots are easy to appear in the processing process, and a turning tool is often damaged by turning, so that the rejection rate is increased. The special half shaft is made of 45# steel materials, the processing is convenient, the hardening and tempering treatment is carried out, and the rigidity strength is better than that of the original half shaft. The split half shaft structure and the design that the groove is matched with the convex body are adopted, so that the half shaft can be rapidly welded in a tight fit manner, and the processing is simple. The half shaft is connected with the flange plate through the flat-head bolt, and the flat-head bolt of the flange plate is easy to loosen due to the vibration impact of the heavy truck during running. The flange plate adopts a counter bore design and is connected by the inner hexagon bolts, so that the inner hexagon bolts can be more tightly connected with the flange plate, the bolts are prevented from loosening, and the service life of the half shaft can be effectively prolonged; the oil guide groove plays a better lubricating role, enhances the wear resistance of the spline and can greatly improve the working durability of the half shaft; the first spline and the second spline structure can effectively improve the bearing capacity of the half shaft.

The utility model has the beneficial effects that: the utility model has reasonable design and easy processing, can effectively prevent the bolt from loosening and can greatly improve the working durability. The split half shaft structure and the design that the groove is matched with the convex body are adopted, so that the half shaft can be rapidly welded in a tight fit manner, and the processing is simple; the flange plate adopts a counter bore design, so that the connection between the bolts and the flange plate can be more compact, the bolts are prevented from loosening, and the service life of the half shaft can be effectively prolonged; the oil guide groove is arranged, so that the working durability of the half shaft can be greatly improved; the first spline and the second spline structure can effectively improve the bearing capacity of the half shaft.

In the figure: 1 half axle left body, 2 recesses, 3 half axle right bodies, 4 convex bodies, 5 ring flanges, 6 counter bores, 7 first splines, 8 second splines, 9 oil guide grooves and 10 thimble holes.

Detailed Description

The utility model is further described below with reference to the following figures and examples:

as shown in fig. 1, a special half shaft for heavy trucks comprises a left half shaft body 1, a groove 2, a right half shaft body 3, a convex body 4, a flange plate 5, a counter bore 6, a first spline 7, a second spline 8, an oil guide groove 9 and a thimble hole 10, wherein the groove 2 is arranged at the right end of the left half shaft body 1, the convex body 4 matched with the groove 2 is arranged at the left end of the right half shaft body 3, the counter bore 6 is arranged at the edge part of the flange plate 5, the first spline 7 and the second spline 8 are arranged outside the right end of the right half shaft body 3, the oil guide groove 9 is arranged between the first spline 7 and the second spline 8, and the thimble hole 10 is arranged at the top end of the left half shaft body and the top end of the right half shaft body.

The half shaft of the heavy truck is generally processed by cast steel materials, air holes or white spots are easy to appear in the processing process, and a turning tool is often damaged by turning, so that the rejection rate is increased. The special half shaft is made of 45# steel materials, the processing is convenient, the hardening and tempering treatment is carried out, and the rigidity strength is better than that of the original half shaft. The split half shaft structure and the design that the groove 2 is matched with the convex body 4 are adopted, so that the half shaft can be rapidly welded in a tight fit manner, and the processing is simple. The half shaft is connected with the flange plate 5 through flat head bolts, and the flat head bolts of the flange plate 5 are easy to loosen due to the shock impact of the heavy truck during driving. The flange 5 is designed by adopting the counter bore 6 and is connected by adopting the inner hexagon bolts, so that the inner hexagon bolts can be more tightly connected with the flange 5, the bolts are prevented from loosening, and the service life of the half shaft can be effectively prolonged; the oil guide groove 9 plays a better lubricating role, enhances the wear resistance of the spline and can greatly improve the working durability of the half shaft; the first spline 7 and the second spline 8 are in structures, so that the bearing capacity of the half shaft can be effectively improved.
