Abstract
The invention relates to the field of modification of Dongfeng EQ145 automobiles, in particular to a gear pair of a main reducing gear and a drive axle. The gear pair of the main reducing gear of the Dongfeng EQ145 automobile is composed of a drive gear and a driven gear which are mutually meshed, and are quasi-hyperbola bevel gears with the modulus being 11.2mm and the offset being 35mm, wherein the teeth number of the drive gear is 5, and the teeth number of the driven gear is 34. The gear pair can be used to replace the gear pair of the main reducing gear of the traditional common automobile directly, has the advantages of not only improving the gradeability of the automobile but also improving the impact force resistance and reducing the fault rate of the modified automobile, can be applied to plateau type modification of the Dongfeng EQ145 automobile and is suitable for being used in severe automobile working environments such as mines and construction sites.
Description
Technical field
The present invention relates to automobile drive axle repacking field, especially east wind EQ145 plain edition and repack plateau type gear pair for main gearbox used and ransaxle into.
Background technique
For adapting to the environment of plateau mountain driving, reduce the repacking cost, normally existing general automobile model is reequiped.The automobile of same power, the reduction speed ratio of the main reducing gear of increasing ransaxle, can improve automobile climbing capacity.The accurate hypoid bevel gear pair that the Driven Gear of Final Reduction Gear of its common plain type ransaxle of east wind EQ145 type automobile is the 6:38 speed ratio.For repacking the ransaxle of plateau type into, usually way is: under the condition that does not change other physical dimension of ransaxle, by main speed reducing gear pair 6:38(1:6.33) change 6:41(1:6.83 into) accurate hypoid bevel gear pair.Reduce like this travelling speed of automobile, improved grade ability.But, owing to not changing other structure of ransaxle and size, the bevel gear boundary dimension of this main reducing gear can not increase, but guarantee velocity ratio by reducing module (by 10.13mm, being reduced to 9.39mm).After the repacking, although improved automobile climbing capacity, the intensity of Driven Gear of Final Reduction Gear and impact resistance all can reduce like this, and easy spring tooth when being subject to equal heavy load or impacting causes the vehicle failure rate to raise.
Summary of the invention
The technical problem to be solved in the present invention is: when the plain type automobile repacking becomes plateau type, the intensity of Driven Gear of Final Reduction Gear and impact resistance reduce, easy spring tooth when being subject to equal heavy load or impacting, and the vehicle failure rate raises.
Be specially: a kind of east wind EQ145 type automobile driving axle main gear box gear pair, by intermeshing driving gear and driven gear, formed, it is characterized in that: the gear pair of the described main reducing gear hypoid bevel gear that is as the criterion, modulus is 11.2mm, Offset 35mm, wherein the number of teeth of driving wheel is 5, and the follower number of teeth is 34.
A kind of east wind EQ145 type automobile drive axle, comprise main reducing gear, differential mechanism, semiaxis and driving axle housing, it is characterized in that described main reducing gear installs above-mentioned gear pair for main gearbox.
Utilize the said gear pair as a kind of east wind EQ145 automobile driving axle main gear box gear, other parts do not need to do any change as differential mechanism, semiaxis and driving axle housing etc., can to plateau type, reequip with completing plain type.
After the repacking, the final driver ratio of east wind EQ145 ransaxle becomes 5:34 by 6:38 like this, and modulus becomes 11.2mm by 10.13mm.So only need simple repacking, just not only improved the grade ability of automobile, improve intensity and the shock-resistant ability of gear simultaneously, lower the vehicle failure rate.Be applicable on mine and construction ground, use in severe automobile working environment.
The accompanying drawing explanation
Fig. 1 is gear pair for main gearbox schematic diagram of the present invention.
Embodiment
The gear pair for main gearbox of the common plain type automobile drive axle of east wind EQ145 is 6:38, and modulus is 10.13mm, and its follower external diameter is 380mm.
As shown in Figure 1, the gear pair for main gearbox hypoid bevel gear that is as the criterion, adopt Gleason tooth system, adds and use the blank same with plain edition man-hour, and material is 20CrMnTiH.Modulus is 11.2mm, middle pressure angle 22
.30 ', Offset 35mm, wherein the number of teeth of driving wheel 1 is 5 teeth, Root angle 9
.38 '; The number of teeth of follower 2 is 34 teeth, Root angle 74.45
.。Velocity ratio is 1:6.8, and the external diameter of follower 2 is in the 380mm left and right.Therefore this gear pair can directly be changed on the ransaxle of east wind EQ145 automobile, and need not do change to other mechanism, can reach the grade ability that has improved automobile, improves intensity and the shock-resistant ability of gear simultaneously, lowers the effect of vehicle failure rate.
Claims (2)
1. an east wind EQ145 type automobile main reducer gear pair, by intermeshing driving gear and driven gear, formed, it is characterized in that: the gear pair of the described main reducing gear hypoid bevel gear that is as the criterion, modulus is 11.2mm, Offset is 35mm, wherein the number of teeth of driving wheel is 5, and the follower number of teeth is 34.
2. an east wind EQ145 type automobile drive axle, comprise main reducing gear, differential mechanism, semiaxis and driving axle housing, it is characterized in that described main reducing gear is equipped with gear pair for main gearbox claimed in claim 1.
