Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element to which the reference is made must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1 and 2 the utility model discloses split type differential mechanism assembly of parallel shaft, planet carrier front end 2, 3 two parts are connected through 10 hexagon head bolts 11 and 5 cylindric locks 19, and drive power is input by the spiral bevel gear of preceding part, transmits for latter part, adopts split type design, realizes the free dismouting of split mechanism through buffering coupling assembling for planet carrier work is more stable.
The rear end 6 of the planet carrier is connected with the front end 3 of the planet carrier through 5 hexagon head bolts 21 and 5 cylindrical pins 20, and the driving force is transmitted to the rear end of the planet carrier from the front end of the planet carrier.
The five planetary gears 5 are uniformly distributed around the sun gear 4 to be meshed with the sun gear, are fixed between the rear end 6 of the planet carrier and the front end 3 of the planet carrier through a planetary gear shaft 13, and are meshed with the outer gear ring 9.
The rear axle output shaft 8 is connected with the outer gear ring 9 through a spline, and power is transmitted to the rear axle output shaft through the outer gear ring.
When the automobile runs straight, the driving force is input by the spiral bevel gear on the front end 2 of the planet carrier, because the resistance forces on the two sides are the same, the planet gear 5 revolves around the sun gear 4 but does not rotate, the outer gear ring 9 and the sun gear 4 rotate at the same speed, and the output is also the same.
When the automobile turns, the driving force is input by the spiral bevel gear on the front end 2 of the planet carrier, and because the resistance on the two sides is different, the planet gear 5 revolves around the sun gear 4 and also rotates, thereby absorbing the resistance difference, enabling the wheels to rotate at different speeds, and ensuring that the automobile smoothly passes through a bend.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
