Utility model content
The purpose of this utility model is to provide a kind of plug-in hybrid drive system, to solve the vehicle bridge abnormal sound problem that existing drive system causes.In order to realize above object, the technical scheme that the utility model adopts is: a kind of plug-in hybrid drive system, comprise driving engine, ISG motor, power-transfer clutch and drive motor, described engine output end is connected with ISG motor one end, the other end of ISG motor is connected with power-transfer clutch, the other end of power-transfer clutch is connected with back axle by transmission shaft, rear axle shaft is connected with wheel with after two-stage reduction gear by corresponding drive motor, and described drive motor is connected with vehicular energy system with ISG motor.
Described driving engine is connected with ISG motor by torsion vibration absorber.
The vehicle with plug-in hybrid drive system of the present utility model, the hybrid electric drive system comprising vehicular energy system and be connected with back axle, described hybrid electric drive system comprises driving engine, ISG motor, power-transfer clutch and drive motor, described engine output end is connected with ISG motor one end, the other end of ISG motor is connected with power-transfer clutch, the other end of power-transfer clutch is connected with back axle by transmission shaft, rear axle shaft is connected with wheel with after two-stage reduction gear by corresponding drive motor, and described drive motor is connected with vehicular energy system with ISG motor.
Described driving engine is connected with ISG motor by torsion vibration absorber.
Plug-in hybrid drive system of the present utility model and use the vehicle of this system, when sliding and brake, control system controls drive motor and exports negative sense moment of torsion, wheel is applied directly to after being turned round by the increasing of two-stage reduction gear reduction of speed, avoid vehicle bridge master to subtract gear and accept forward and negative sense torsional interaction frequently, effectively can reduce vehicle bridge abnormal sound and the main generation subtracting gear failure phenomenon.
In addition, drive motor be arranged in from wheel more close to position, during pure motor driving, driving efficiency is higher; The application of secondary gear reducer can improve the hill climbing ability of plug-in hybrid vehicle.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of hybrid electric drive system;
Fig. 2 is the structural representation with plug-in hybrid drive system vehicle.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
Be illustrated in figure 1 the schematic diagram of the utility model plug-in hybrid drive system embodiment, as seen from the figure, this system comprises driving engine 1, ISG motor 3, power-transfer clutch 4 and drive motor, driving engine 1 is connected with ISG motor 3 by turning bumper 2, the other end of ISG motor 3 is connected with power-transfer clutch 4, the other end of power-transfer clutch 4 is connected with back axle by transmission shaft, rear axle shaft is connected with wheel by corresponding drive motor 51,52 and two-stage reduction gear 61,62 are rear, and drive motor and ISG motor are used for being connected with vehicular energy system 8 by integrated manipulator 7.
As shown in Figure 2, the utility model additionally provides a kind of vehicle with plug-in hybrid drive system, comprise vehicular energy system and the hybrid electric drive system for being connected with back axle, the structure of described hybrid electric drive system is described above, this front part of vehicle is operator's compartment 9, rear portion is hyperbaric chamber 10, the vehicular energy system 8 described in placing in hyperbaric chamber.
Drive system of the present utility model has following mode of operation:
(1) pure motorized motions pattern: during vehicle start, when battery electric quantity is sufficient, driving engine does not start, disengaging of clutch, is powered to two drive motor by vehicular energy system, and after drive motor is turned round by the increasing of retarder reduction of speed, Direct driver vehicle travels.Control system calculates car load power demand according to the operation of chaufeur and actual condition, adjusts rotating speed and the moment of torsion of drive motor in real time.Pure motorized motions multi-mode low noise, zero-emission, pollution-free.
(2) the independent drive pattern of driving engine: when car load demand power is greater than two drive motor power sums, and when being less than the maximum exportable power of driving engine, power-transfer clutch combines, and two drive motor idle running, control system controls driving engine and drives separately vehicle to travel.In this process, for improving fuel economy and the efficiency of driving engine, according to the state of battery electric quantity, the power of adjustment driving engine output in real time, control engine operation in fuel efficient district, rich energy is stored in vehicular energy system by ISG electric power generation.
(3) drive pattern is combined: the chaufeur recognition function utilizing system, control system calculates car load demand power.When car load demand power is greater than the maximum exportable power of driving engine, and battery electric quantity is sufficient, then power-transfer clutch combines, and driving engine and two drive motor are combined and driven vehicle to travel.Control system can calculate demand torque according to car load demand power, by moment of torsion reasonable distribution, controls rotating speed and the moment of torsion of driving engine and drive motor output the best.
(4) to slide and braking mode: when detect vehicle be in slide or braking mode time, whether control system is separated according to current vehicle speed control clutch, and whether driving engine shuts down; Two drive motor are now in generating state, and kinetic energy when being braked by car load is stored in vehicular energy system by transformation of energy.
Above embodiment only understands core concept of the present utility model for helping; the utility model can not be limited with this; for those skilled in the art; every according to thought of the present utility model; the utility model is modified or equivalent replacement; any change done in specific embodiments and applications, all should be included within protection domain of the present utility model.
