Description
Technical field
The invention belongs to vehicular propulsion, relate in particular to the torque transfer that primary mover comprises motor and combustion engine combination.
Background technology
(Hybrid-Electric Vehicle HEV) compares with pure electric automobile and internal-combustion engines vehicle hybrid vehicle, has many advantages at aspects such as dynamic property, the feature of environmental protection.It is equipped with driving engine and motor two cover systems simultaneously, can use electric motor starting during starting, and two cover systems can be exerted oneself simultaneously when acceleration and upward slope; Brake, can realize energy recovery when sliding, therefore can save the fuel oil about 40%, tail gas pollution also reduces half.Just because of two cover power system coordinated, so compare with automobile with class, the oil consumption of hybrid vehicle and the corresponding minimizing of discharging, discharging can improve at least one rank.
Tandem (SHEV) is the common type of attachment of hybrid power, the common configuration of this connection mode is directly to drive motor by driving engine to generate electricity, then electric energy storage is arrived storage battery, storage battery resupplies motor, by change speed gear box, back axle, transfer torque to wheel, and then powered vehicle starts to walk, travels; Simultaneously in braking, energy is recyclable when sliding.This device defect is obvious, and the energy transmission device complex structure has increased multistage transfer chain, the energy multiple conversions, and active loss is big, and driving efficiency is low.
Summary of the invention
For overcoming the defective of prior art, the purpose of this invention is to provide a kind of power transmission device for hybrid electric vehicle, simplified structure, safe and reliable, improve driving efficiency.
Power transmission device for hybrid electric vehicle, connect to form successively by driving engine, power-transfer clutch, motor and change speed gear box, be characterized in: clutch-bell cover is fastened on the driving engine, clutch device is in clutch-bell cover, connect driving engine and change speed gear box input shaft, realize the transmission of power of driving engine to change speed gear box; Motor is installed between power-transfer clutch and the change speed gear box, an electric machine casing left side is fastenedly connected with clutch-bell cover, right and change speed gear box front end cover is fastenedly connected, stator assembly is fastened in the electric machine casing, armature is by bearing set supporting, location, be installed on electric machine casing and the change speed gear box front end cover, and be sleeved on the change speed gear box input shaft, realize the transmission of power of motor to change speed gear box; Motor cavity and change speed gear box inner chamber are separated by oil sealing, and sealing;
Described change speed gear box input shaft is established key shape projection, by power-transfer clutch, is connected with the change speed gear box input shaft, and the power of driving engine output is delivered to change speed gear box through power-transfer clutch, change speed gear box input shaft, realizes the engine power transmission.
Described armature is established key shape groove and is matched with the key shape projection that the change speed gear box input shaft is established, and armature is sleeved on the change speed gear box input shaft, is connected by key, and Motor torque is delivered to change speed gear box.
When vehicle operating, the separation that the car load control setup can control clutch with combine, control motor operating state.Power-transfer clutch is in bonding state, and the output torque of driving engine to change speed gear box input shaft, change speed gear box, output to wheel then, thereby powered vehicle is travelled by clutch transmits; Power-transfer clutch is in released state, and the control machine operation is delivered to change speed gear box with Motor torque by the change speed gear box input shaft, and then outputs to wheel, and powered vehicle is travelled; Power-transfer clutch is in bonding state, controls machine operation simultaneously, by motor and simultaneous firing, and output torque, powered vehicle is travelled.
These three kinds of mode of operation can be implemented by the car load control setup according to different operating modes;
In car brakeing, motor is in generating state when sliding, electric energy input storage battery can carry out the recovery of energy.
Compared with prior art, advantage is that members such as driving engine and motor and power-transfer clutch, change speed gear box carry out multiple optimization of matching under car load control setup control, thereby guaranteeing that vehicle is under complex working condition moves under the optimum state, and blowdown reduces, and oil consumption reduces; This apparatus structure is brief, reasonable simultaneously, and it is little to take up room; Easy for installation, be easy to control, safe and reliable.
Description of drawings
The invention will be further described for the contrast accompanying drawing.
Fig. 1 is the power transmission device for hybrid electric vehicle connection diagram.
The specific embodiment
As seen from Figure 1, the present invention is connected with change speed gear box 14 successively by driving engine 1, power-transfer clutch 2, motor 8.Armature 10 is sleeved on by key shape groove 11 on it on key shape projection 4 of change speed gear box input shaft 3, and armature 10 is delivered to motor 8 moments of torsion on the change speed gear box input shaft 3 by the key cooperation, and then moment of torsion is exported by change speed gear box 14; Armature 10 is to be supported, located by bearing set 7, is installed on motor 8 housings and the change speed gear box front end cover 12; Motor 8 housings tighten together by bolt (not outpouring among the figure) and change speed gear box front end cover 12, and stator assembly 9 tightens together by interference fit with motor 8 housings; Clutch-bell cover 5 tightens together by bolt 6 and motor 8 housings; Oil sealing 13 separates motor 8 cavitys and change speed gear box 14 cavitys and seals; Driving engine 1 tightens together by bolt (not outpouring among the figure) with clutch-bell cover 5; Power-transfer clutch 2 is installed in the clutch-bell cover 5, and driving engine 1 and change speed gear box input shaft 3 are coupled together, realize driving engine 1 moment of torsion is delivered to change speed gear box 14, and output.
