Abstract
The invention discloses an automobile rear axle assembly which comprises a rear axle, a speed reducer and a driving motor. The speed reducer comprises a speed reducer shell, a middle shaft and a differential mechanism. The speed reducer shell is integrally cast and formed. A motor shaft of the driving motor extends in the speed reducer shell from the left side or the right side and is meshed with a middle gear on the middle shaft for transmission through a driving gear on the motor shaft. The driving motor is installed on a motor installation flange of the speed reducer shell. A left half shaft of the rear axle is inserted in the left side of the differential mechanism. A bevel gear on the left half shaft is driven by a bevel gear of the differential mechanism to rotate. A right half shaft of the rear axle is inserted in the right side of the differential mechanism. A bevel gear on the right half shaft is driven by the bevel gear of the differential mechanism to rotate. The speed reducer is connected with the rear axle through a rear axle installation flange at the bottom of the speed reducer shell. The automobile rear axle assembly is small in size, convenient to install and low in cost, the motor shaft of the driving motor serves as an input shaft, gears of a transmission are all wrapped in the shell, noise is low, oil leakage risk is reduced, and lubricating oil is saved.
Description
Technical field

Background technology
Automobile is divided into front driving type or rear-guard formula, is arranged on back axle by decelerator, is slowed down by driving driven by motor
Device, then driven the left and right semiaxis of back axle to rotate, for rear-guard formula by decelerator.Decelerator on back axle mostly is point
Body formula structure, dimensions is relatively big, installs complexity, and then bridge locational space is limited, arranges pretty troublesome.
It addition, traditional split type decelerator, manufacture, design cost the highest；Decelerator all with power shaft,
Jackshaft and differential mechanism, power shaft by drive motor motor shaft drive, as spline connect, structure also than
More complicated.
Summary of the invention
It is desirable to provide a kind of volume is little, easy for installation, the automobile axle assembly of low cost of manufacture, save
Remove the power shaft of decelerator, the motor shaft driving motor used as power shaft.
To this end, the technical solution adopted in the present invention is: a kind of automobile axle assembly, including back axle, subtract
Speed device and driving motor, described decelerator includes reducer shell, jackshaft, differential mechanism and bearing (ball) cover,
Idler gear, idler gear and the central gear engaged transmission on differential mechanism it is provided with on described jackshaft,
Described reducer shell uses integrally casting shaping, drives the motor shaft of motor to stretch into from left side or right side and subtracts
In speed device housing, and by the driving gear on motor shaft and the idler gear engaged transmission on jackshaft,
Described bearing (ball) cover is positioned at the reducer shell side away from driving motor shaft insertion hole, and solid by screw
It is scheduled on reducing gearbox external, drives motor to be arranged on the motor mounting flange of reducer shell, back axle
Left half axle insert the left side of differential mechanism, the bevel gear of differential mechanism drive the bevel gear on left half axle to rotate,
The right axle shaft of back axle inserts the right side of differential mechanism, the bevel gear of differential mechanism drive the bevel gear on right axle shaft
Rotating, described decelerator is connected with back axle by the back axle mounting flange bottom reducer shell.
Preferred as such scheme, described bridge mounting flange is circular discs, reducer shell bottom
The left and right sides is downwardly extending semicircular installation journal stirrup, each installation journal stirrup equipped with a semicircular ring,
What the two ends, left and right of described differential mechanism were respectively placed in correspondence installs in the circular hole that journal stirrup and semicircular ring surround, peace
Dress journal stirrup passes through screw lock together with corresponding semicircular ring, it is achieved thereby that the suspension of differential mechanism is installed.
Optimize differential mechanism installation on reducer shell, it is ensured that install reliable.
Further, described motor mounting flange is rectangular disk, and rectangular disk is provided with four rectangular cloth
The motor installing hole put, motor installing hole is connected by reinforcement with driving motor shaft insertion hole, improves electricity
The intensity of machine mounting flange.
Beneficial effects of the present invention: optimizing structure and arrange, volume is little, easy for installation, low cost, slows down
Device eliminates power shaft, the motor shaft driving motor use as power shaft, directly drives on jackshaft
Idler gear rotate；The gear of speed changer is all wrapped in housing, and noise is little, decreases leakage of oil wind
Danger, saves lubricating oil.
