Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
Chu, be fully described by, it is clear that described embodiment be only a part of embodiment of the present invention rather than
Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation
The every other embodiment obtained under property work premise, broadly falls into the scope of protection of the invention.
A kind of agricultural machinery high-clearance 4 wheel driven propons as shown in Fig. 1 to Fig. 4, including differential mounting 12 and propons
The driving axle housing of shell 11 composition, described differential mounting 12 and front axle housing 11 are formed in one structure, described
Connecting in front axle housing 11 and have overall semiaxis 1, described overall semiaxis 1 end connects driving bevel gear 7, institute
Stating driving bevel gear 7 and hub reduction gear connects, described hub reduction gear includes decelerating casing and drive shell
Body, is provided with vertical shaft sleeve pipe 9, is provided with transmission vertical shaft by bearing in vertical shaft sleeve pipe 9 in described decelerating casing
13, described transmission vertical shaft 13 upper and lower side is connected to bevel gear 10 and lower bevel gear 4, upper bevel gear
10 engage with driving bevel gear 7, the output cone on the output shaft connected in lower bevel gear 4 and hub reduction gear
Gear 8 is meshed, and is also associated with steering arm 2, described steering arm 2 and wheel limit and subtracts above described hub reduction gear
The fixing connection of output shaft on speed device, the physically end face of described decelerating casing and lower surface are provided with screw also
Carry out threaded with decelerating casing upper end cover 18 and decelerating casing bottom end cover 19 respectively, described drive housing
The left side of entity is also equipped with screw, this screw and drive housing end cap 3 are threaded, defeated in drive housing
The centrage of shaft is 98-120mm with the distance of overall semiaxis 1 centrage of propons, the master of this 4 wheel driven propons
Speed reducing ratio is 4.333-5.368.
Due to the fact that and differential mounting 12 and the front axle housing 11 of assembling differential mechanism 5 are designed as one, institute
Welding position is eliminated, fall with the technology by front axle housing 11 and differential mounting 12 compared to conventional art
Low cost provides against hidden trouble so that driving axle housing becomes an entirety, eliminates loaded down with trivial details installation procedure, and
Owing to the present invention is integrated, the connection rigidity between differential mounting 12 and front axle housing 11 is strong, no
Easy fracture, damage；Change the major semiaxis 15 and semi-minor axis 16 that connect u-shaped fork 14 into an entirety half simultaneously
Axle 1, would not produce concentricity this hidden danger inconsistent.
In conventional technology, front axle housing 11 is easily encountered by more ground foreign material, particularly when dilatory
Machine is in the working environment that some mud are deep, owing to front axle housing 11 is liftoff relatively low, and long-term mason
Make, front axle housing 11 intermediate transmission oil sealing can be caused to be damaged by the foreign material in muddy water, thus loss of seal effect；
Such as Fig. 5, the present invention is by the distance of the centrage of drive housing output shaft Yu the centrage of the overall semiaxis 1 of propons
H is set to 98-120mm, thus simple and effective overcomes dilatory front axle drive oil sealing fragile and leakage of oil is asked
Topic, and then improve the overall serviceability of farm tractor front axle.
Due to the physically end face of described decelerating casing and lower surface be provided with screw and respectively with on decelerating casing
End cap 18 and decelerating casing bottom end cover 19 carry out threaded, and the left side of described drive housing entity is also provided with
Having screw, this screw and drive housing end cap 3 are threaded, say, that beaten compared to conventional screw 6
Entering box house, leakage of oil hidden danger is stopped in this design completely, solves all Leakages comprehensively, saves work
Time, reducing cost, this product qualified effect height, durable, processing is simple simultaneously, and assembling also reduces by percent 30
Technique, the assembly cost of percent 30 and welding cost, improve percent 70 concentricity and quality simultaneously,
The base ratio of the present invention is 4.333-5.368, and base ratio refers to the gear of main reducing gear in automobile drive axle
Gear ratio, it than the angular velocity of rotation of upper axle half shafts, is also equal to them equal to the angular velocity of rotation of power transmission shaft
The ratio of rotating speed, use this speed reducing ratio, both can guarantee that the preferable economy of fuel, also can guarantee that preferably
Acceleration and climbing capacity, present invention saves man-hour, reduces cost, this product qualified effect height, durable
Stable.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this
Within bright spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in this
Within bright protection domain.
