Description

A kind of pure electric vehicle integrated form dynamical system
Technical field
This utility model relates to a kind of dynamical system, particularly to a kind of pure electric vehicle integrated form dynamical system.
Background technology
Electric automobile has the feature such as energy-saving and environmental protection, cleaning, and having the biggest development potentiality should with wide Use prospect.Electric automobile uses motor to instead of traditional automobile engine, and motor can load startup, And meeting automobile by reasonably configuration and use requirement, this is the biggest difference with electromotor, in electric motor car On still use multi-speed transmission the most improper, if but cancel variable speed drive, then be difficult to take into account automobile and climb Slope and the requirement, particularly small and medium-sized car such as run at high speed, it is necessary to for motor operating characteristic again Design electric automobile gear actuating device.Present electric motor car uses the reducer arrangement without gear substantially, by Motor completes the task of speed change.According to the characteristic curve to motor, slow down without gear and be difficult to make motor work At high efficiency range, causing greatest problem is exactly that starting current is big, climbs unable, and low speed electric current is big, adds at a high speed Not going up, power consumption is excessive, even can damage battery, motor and controller etc..
In order to improve the performance of the dynamical system of pure electric vehicle, some few speed transmission are used, existing Having in technology, patent CN201410828980 proposes and utilizes lock unit gearshift to realize based on single single-stage The two speed transmission design of formula planet circular system, patent CN201410093459 then utilizes coordinated type lock unit Realize design based on single single stage type planet circular system two speed transmission, CN201410243816 profit simultaneously Design based on single single stage type planet circular system two speed transmission is realized with brake and lock unit.But should Prior art there is a problem in that one, designed gear ratio is relatively big, is easily caused shift process impact existing As, the same axiation Integrated design of two, unrealized motor and drive axle, not only structure is the compactest, and passes through Multi-stage transmission behind efficiency is relatively low, three and unrealized parking assist function, and car load power train also needs to arrange auxiliary Halting mechanism.
Utility model content
This utility model is for solving above-mentioned technical problem, it is provided that a kind of gear ratio reducing few gear dynamical system, Realize the same axiation of motor and jack shaft, and the pure electric vehicle integrated form dynamical system of parking assist.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of pure electric vehicle integrated form moves Force system, including housing, double-pinion planetary train mechanism, drives motor and clutch;Described two-stage planet wheel It is that mechanism includes the first sun gear, expert's star-wheel, layman's star-wheel, the first row carrier and the first gear ring;Described Driving machine shaft and the first sun gear rotating shaft to connect, described first sun gear engages with expert's star-wheel, described Expert's star-wheel engages with layman's star-wheel, and described layman's star-wheel and the engagement of the first gear ring, described expert's star-wheel is with outer Planetary gear is arranged in the first row carrier;Described housing is provided with the first row carrier brake;Described the first row Carrier is connected by clutch and the first sun gear;Described first gear ring is provided with the first gear ring output revolving shaft, Described first gear ring output revolving shaft is connected with driving wheel;Described first sun gear rotating shaft, drive machine shaft, First gear ring output revolving shaft and live axle are coaxially disposed;
Providing the benefit that: when vehicle is at low-range drive mode, now the first row carrier brake is in system Dynamic state, clutch are in released state.So, the first row carrier is braked.When the rotor driving motor Rotating clockwise, when vehicle advance travels, now the fixed shaft gear train that acts as of double-pinion planetary train mechanism subtracts Speed device i.e. gear ratio is: the gear ring number of teeth/sun gear number of teeth in k1=double-pinion planetary train mechanism, the power of motor from Sun gear is delivered to the first gear ring through two grades of asteroid wheels, and the first gear ring is dynamic by the first gear ring rotating shaft output Power is to driving wheel, and now driving wheel can obtain respective drive moment of torsion required when starting and speed, can have Effect adapts to the power demand that vehicle is waited on startup;
