Background technique
At present, due to the pressure of energy-saving and emission-reduction, automobile energy-saving reduces discharging standard increasingly stringent.In order to reduce the energy consumption of vehicle, develop the numerous new vehicle systems comprising hybrid vehicle.Hybrid vehicle, as having the long mileage of conventional internal combustion rolling stock and electric automobile energy saving, environmental protection concurrently, can use the vehicle class of clean electric energy to start to be widely used.Also have some vehicles to ensure reliability, the Economy of vehicle and reducing manufacture cost etc. simultaneously, there is plural power source.Such as there are some special purpose vehicles of assistant engine, engineering machinery, super sized type vehicle, special safety vehicle etc.Comprise other power form in addition, as hydraulic hybrid, pressure hybrid power (pressurized air mixed power) etc.These vehicles all need one by the power coupling in two or more different dynamic source, jointly or respectively drive the system of vehicle---dynamic coupling system.The requirement of dynamic coupling system is that the power that plural power source can either be exported individually is delivered to (as wheel etc.) on output unit, and the power that plural power source can be exported again is delivered on output unit simultaneously.
But current can realize above-mentioned functions dual power source dynamic coupling system, mainly comprise following several form:
1 adopts planetary pinion coupled modes.Typical apply comprise Toyota general sharp this, the automobile such as general fertile Lan Da;
2 adopt angle transmission speed variator.Typical apply comprises Nan Che group hybrid power passenger car;
3 adopt coaxial coupling, be arranged on driving engine chain, rely on plural clutch to realize different output modes by motor.
But there are the following problems for current coupled system:
Mode 1 pair of planetary pinion processing, assembly precision require high, and transmission efficiency is low, bad with the production technology inheritance of existing vehicle drive system, needs again used device, mould etc.
Mode 2 adopts bevel gear tooth system high to Gear Processing required precision, lubricating difficulties etc.
There are two power source speed and coordinate fixing in mode 3, is difficult to play the problems such as the optimum-curve for operation of each power source.
No matter which kind of mode above-mentioned, how its power assembly cost all costly, reduces number of spare parts, reduces power system cost and becomes important topic.
The utility model can solve the problems referred to above of dual power source dynamic coupling system.
Summary of the invention
It is simple that the technical problems to be solved in the utility model is to provide a kind of structure that two or more power source can be transferred to the power flexible communication of wheel, the retarder of reliable performance or speed changer, existing speed changer manufacturing mechanism, technique, part can also be made full use of simultaneously, to reduce the first input cost of system to greatest extent, and the most simplification of implementation structure.
In order to solve the problems of the technologies described above, the technological scheme that the utility model is taked is: comprise input shaft (1), casing (2), gearshift (4), motor driving gear (5), motor (6), driving gear B(7), driven gear (8), output shaft (9), it is characterized in that: on input shaft (1), by gearshift (4), driving gear B(7 is installed), when gearshift (4) is in neutral position state, driving gear B(7) freely can rotate relative to input shaft (1); Motor (6) is by motor driving gear (5) and driving gear B(7) engage.
Fixed speed ratio drive connection is kept between such motor (6) and output shaft (9), engine power can pass through clutch (10) and be input to input shaft (1), when gearshift (4) is connected to and puts into gear position, engine power can pass through driving gear B(7), driven gear (8) is transferred to output shaft (9).
Technological scheme can also increase comprise driving gear A(3 for a pair) driving gear pair of driven gear (8), form the hybrid electric drive system of motor two speed ratio speed change.Also some hybrid electric drive systems driving and driven gear and gearshift (4) being formed to motor more multiple gear ratios can be increased.
In technological scheme, motor (6) can be not only power-actuated dynamic power machine, also can change oil hydraulic motor or pneumatic motor into, forms the mixed power system that motor mixes with hydraulic pressure or pressurized air.What access from input shaft (1) also can be motor or other power sources, and as system is provided with automatic control system or other synchronizers, clutch (10) also can be cancelled.
The gearshift (4) mentioned in technological scheme, its structural type can be unrestricted, and the synchronizer gearshift that automobile can be selected common also can use engaging sleeve even straight-tooth sliding gear gearshift.
In the utility model during vehicle backing, driven by motor (as the motor) counterrotating of fixed speed ratio transmission, also can special reverse gear be set in systems in which, realize motor and rotate forward the car-backing function under driving.But on the vehicle based on electric drive, the driving force of motor is enough, and does not also allow the too high speed of a motor vehicle and acceleration, so can omit reverse gear during reversing.
The beneficial effects of the utility model use less number of spare parts, just can realize power coupling drive path the most flexibly, the multiple drive modes of single motor can be realized, under the condition with control and actuator automatically, the power failure-free Transmission System in motor auto-compensation engine gear power gap can also be formed.
In order to reduce whole power assembly cost further, part involved by the utility model also can be designed to one with one or more component integrations of motor, motor, clutch, differential mechanism, main reducing gear, to reduce the number of spare parts such as housing, link, supporting element, improve system rigidity, reduce noise, life-saving, reduces costs and improves car load assembling beat.
The utility model can be widely used on the various power equipments such as automobile, rail vehicle, boats and ships, engineering machinery, farm machinery.
