Axle reduction box assembly belongs to pure electric vehicle commercial vehicle technical field.
Background technique
Currently, the technology path of commercial vehicle pure electric vehicle power assembly mainly has: 1) after motor+AMT+ transmission shaft+tradition
Bridge；2) central integrated form electric drive axle (motor is horizontal+cylindrical gear pair slows down, there is two kinds of different shaft type and coaxial-type), represents enterprise
Industry has BYD, moral to receive.
But 1) technical solution of " motor+AMT+ transmission shaft+tradition rear axle ", which has the disadvantage in that, need to be driven axis connection
AMT and drive axle, weight weight；2) presence of the variable speed of transmission shaft and transmission angle, so that entire power-transmission system
Efficiency is lower, shakes larger.Motor is horizontal so that when high speed whole bridge NVH is asked in the technical solution of " central integrated form electric drive axle "
Topic protrudes, because motor (12000rpm-15000rpm) is much higher compared with Transmission Engine revolving speed (2000rpm-2500rpm), to protect
The NVH of dynamical system is demonstrate,proved, therefore the machining accuracy of gear need to be improved；Universal component rate is low simultaneously, at high cost, craftsmanship is poor.
Summary of the invention
It is an object of the invention to be directed to the problems such as existing power-transmission system efficiency is lower or at high cost, provide
A kind of longitudinal coaxial-type shift electric drive axle reduction gearbox assembly.
To achieve the above object, the technical solution of the invention is as follows: a kind of longitudinal coaxial-type shift electric drive axle subtracts
Fast box assembly, including motor, an axle assembly, countershaft assembly, main cone axle assembly and differential assembly, the countershaft assembly
Including jackshaft, jackshaft constant mesh gear and jackshaft bootom gear, the jackshaft constant mesh gear and jackshaft
Interference is socketed on jackshaft bootom gear respectively, and the main cone axle assembly includes drive bevel gear, main cone axis low grade tooth
Wheel and fixed toothholder, are connected between the main cone axis low regime clutch and drive bevel gear by needle bearing, the fixation
Toothholder is fixed in drive bevel gear, and the differential assembly includes driven wheel of differential, and the motor and an axle assembly connect
It connects, is engaged between an axle assembly and countershaft assembly by jackshaft constant mesh gear, in the countershaft assembly
Between axis bootom gear be meshed with the main cone axis low regime clutch of main cone axle assembly, the main cone axle assembly and an axle assembly it
Between by slidably engaging set connection, and main cone axle assembly and an axle assembly are coaxial, the drive bevel gear of the main cone axle assembly and
The driven wheel of differential of differential assembly is meshed, the differential gear and wheel half axis connection of end of the differential assembly.Further include
There are transmission case and reducing gearbox, be bolted between the transmission case and reducing gearbox, the jackshaft is total
It is supported in transmission case at by the cone bearing of two sides, the main cone axle assembly is fixed on reducing gearbox by cone bearing
On, the differential assembly is fixed on reducing gearbox by cone bearing, and an axle assembly passes through bearing and speed changer
Shell connection.
The motor is longitudinal.
Compared with prior art, the beneficial effects of the present invention are:
It 1, include motor, an axle assembly, countershaft assembly, main cone axle assembly and differential assembly in the present invention, with existing " electricity
Machine+AMT+ transmission shaft+tradition rear axle " structure is compared, and transmission shaft is eliminated, and reduces system self weight, while improving assembly
Power transmission efficiency；Realize that AMT lacks shelves and reduces system cost while taking into account dynamic property.
2, the present invention in motor it is longitudinal, compared with existing " central integrated form electric drive axle " structure, main cone axle assembly and
The components such as differential assembly can borrow traditional axle, and universal component rate is high；And by traditional axle transform as electric drive axle bridge at
This and technical threshold are low.Meanwhile the present invention can carry out gear shift, when low or first gear, power passes through jackshaft constant mesh gear, jackshaft
Bootom gear, the transmitting of main cone axis low regime clutch, motor speed is lower at this time, therefore roller gear precision can be kept and existing speed change
The case accuracy of gear is consistent, and Cylinder Gear turbine adds required precision low, and without further increasing precision, good manufacturability is at low cost；At a high speed
When shelves, power drive mechanism is consistent with existing traditional axle power train, and power is directly transmitted by drive bevel gear, and roller gear is not
The problems such as progress power transmitting, technical maturity is high, is not in NVH, roller gear is because of transmitting torque production when avoiding high speed
The raw risk uttered long and high-pitched sounds.
