First travelling gear is connected by the first power transmission shaft and power set, and the power set are arranged at the another of car body or vehicle bridge
Side, the first travelling gear are meshed with the second travelling gear；
Second decelerator includes the 3rd travelling gear, the 4th travelling gear and differential mechanism, and the 3rd travelling gear passes through
Second driving shaft and the second travelling gear are connected, and are meshed with the 4th travelling gear, the 4th travelling gear and differential mechanism
Drive connection；
First power transmission shaft and second driving shaft are horizontal setting, and perpendicular with the travel direction of vehicle.
Further, first power transmission shaft and second driving shaft are universal drive shaft.
Further, the power set are motor.
Further, the diameter of first travelling gear is less than the diameter of the second travelling gear.
Further, the diameter of the 3rd travelling gear is less than the diameter of the 4th travelling gear.
Prior art is different from, above-mentioned technical proposal has the following advantages that：By the way that main reducing gear is divided into the first decelerator
With two parts of the second decelerator, and the first power transmission shaft, second driving shaft both ends are made to make power towards vehicle frame or the both sides of vehicle bridge
Input shaft is parallel with power output shaft, avoids and is accounted for using space caused by orthogonal power input shaft and power output shaft
With.Rear overhang is reduced using horizontal power set, and has conceded the space for being formerly used for laying power transmission shaft, is easy to new-energy automobile
Battery set, improve vehicle rate of actual loading.By the way that power assembly and the first decelerator are respectively arranged at into car body both sides, ensure
The minimum length of power transmission shaft, ensure that the transmission efficiency during vehicle use.

Embodiment
To describe the technology contents of technical scheme, construction feature, the objects and the effects in detail, below in conjunction with specific reality
Apply example and coordinate accompanying drawing to be explained in detail.
Referring to Fig. 1, present embodiment discloses a kind of split type main reducing gear, power set 201 and speed changer 301 connect
In the side of car body 101 (power is transferred into the first power transmission shaft after in the present embodiment, power set are by speed changer).
The power intake of power set 201 and speed changer 301 is connected, and the first decelerator 401 is connected to the another of car body 101
Side, including the first travelling gear 402 and the second travelling gear 403.First travelling gear 402 is by the first power transmission shaft 501 with becoming
The pto connection of fast device 301, and the second travelling gear 403 is meshed.Second decelerator 601 includes the 3rd and passed
Moving gear 602, the 4th travelling gear 603 and differential mechanism 604, the 3rd travelling gear 602 are passed by second driving shaft 701 and second
Moving gear 403 is connected, and the 3rd travelling gear 602 is meshed with the 4th travelling gear 603, the 4th travelling gear 603
