Description
Technical field
The utility model is related to planetary pure electric vehicle dynamical system and commercial car.
Background technology
Pure electric automobile have become cleaning, efficient automobile developing direction, be solve environmental protection and power saving best way
One of diameter and the inevitable choice of Domestic Automotive Industry sustainable development.Pure electric automobile is using which kind of power configuration as dynamic
Force driving device, it has also become the hot spot of current pure electric vehicle power research on system technology.Wherein, commercial car dynamical system also by
Gradually develop to pure electric vehicle direction, the dynamical system of pure electric vehicle commercial car mainly uses single motor+gearbox driving, motor at present
It directly drives, the configurations such as bi-motor directly drives.Single motor, Dual-motors Driving configuration to motor output torque and rotating speed require compared with
Height, though single motor+gearbox driving configuration reduces the torque and rotating speed of motor, the shift problem and work(Single-issue of itself are not
Market needs can be met.Pure electric vehicle commercial car dynamical system is primarily present problem at present：Single motor+transmission system configuration, nothing
By being using automatic or manual transmission, during driving, due to shifting gears, there are power interruption, shift process irregularities etc.
Problem influences vehicle acceleration and driving experience；In braking process, if carrying out gear shift operation, this stage vehicle is turned round without electric braking
Square, vehicle braking deceleration can be mutated reduction and there is braking risk, driver can be forced to step on brake pedal deeply, be braked using gas/liquid
Slow down speed, influence energy regenerating, so such system cannot carry out gear shift operation in braking, keeps current shift system
It is dynamic.But it is influenced under this state by drive system efficiency, electric energy recycling is uncontrollable.Motor direct-drive configuration has single motor direct
Driving and bi-motor directly drive two kinds of patterns, and major defect is that motor weight is big, power is big, most of working time of vehicle
It is interior, it does not need dynamical system and plays maximum torque and power, lead to the power redundancy, of high cost of dynamical system.
Based on two kinds of systems there are the problem of, in conjunction with the actual demand of pure electric vehicle commercial car, there is an urgent need for develop more reasonably
New dynamical system configuration.
It is public in the Chinese patent document that Authorization Notice No. is CN206528310U in order to solve the problems, such as that existing system exists
A kind of pure electric vehicle power assembly system, including two motors and a planet row have been opened, in low speed, single motor drives,
The two common output of motor power coupling, ensures needed for power when high speed.Although the system can be selected according to different needs
Different motor drive modes is selected, still, which only realizes that single motor driving or two motors drive output jointly
Two kinds of drive modes, each drive mode cannot be further divided into different operating modes, also cannot be according to different power
Demand carries out the switching of corresponding operating mode, i.e., suitable operation range can not be further switched to according to actual demand,
Under inappropriate operating mode, it is possible to motor can be caused not work in high efficiency region, in turn result in system working efficiency
It is not high.

Specific implementation mode
Commercial car embodiment
The present embodiment provides a kind of commercial car, including a kind of planetary pure electric vehicle dynamical system further includes certainly others
Component part.But since other components are not the protection points of the utility model, it just no longer illustrates here,
Planetary pure electric vehicle dynamical system is described in detail below for Fig. 1.Certainly, planetary pure electric vehicle dynamical system and not only
It is only applicable to commercial car, can be applicable to other kinds of vehicle.
Planetary pure electric vehicle dynamical system includes first motor, the second motor and the first transmission mechanism, and first motor corresponds to
Motor 1 in Fig. 1, the motor 8 in the second motor corresponding diagram 1.In the present embodiment, the first transmission mechanism is by taking planet row as an example, certainly,
First transmission mechanism is not limited to planet row, and as other embodiments, the first transmission mechanism can also be other mechanisms, than
Such as：Single clutch, clutch and the transmission mechanism of transmission gear composition or existing deceleration mechanism etc. can also be
Simple transmission shaft.
Planet row includes three ends, claims first end, second end and third end respectively, since three ends of planet row are respectively
