Description
Technical Field
The invention belongs to the field of gearboxes, relates to a hybrid gearbox, and particularly relates to an integrated hybrid gearbox with motor locking and oil pumping functions.
Background
At present, a generator of a hybrid power transmission mainly bears a power generation function, and the generator is required to be locked when the engine is in a direct-drive mode so as to achieve efficiency maximization. At present, the locking of generator is generally realized and is broken away from to the cooperation that uses between friction disc, steel sheet, the cylinder in the locking of generator, and in the operating mode of parking electricity generation, the gearbox generally adopts external auxiliary pump work to carry out the oil circuit lubrication.
The existing generator locking mode can increase sliding friction pairs when the gearbox operates, reduce the efficiency of the gearbox, cause nonmetal abrasion during operation and reduce the cleanliness of the gearbox; meanwhile, the mode of externally connecting the oil pump has the defects of short service life and high price of the oil pump.
Through a search for a patent publication, no patent publication that is the same as the present patent application is found.
Disclosure of Invention
The invention aims to provide the integrated hybrid gearbox with the motor locking and oil pumping functions, which has the advantages of scientific and reasonable structural design, improvement of the efficiency of the gearbox, guarantee of the cleanliness in the gearbox, prolongation of the service life of an oil pump, reduction of the maintenance cost and easiness in realization.
The technical problem to be solved by the invention is realized by the following technical scheme:
the utility model provides an integrated form thoughtlessly moves gearbox with motor locking and pump oil function, includes the gearbox body this internal planet row that is provided with of gearbox is connected with the engine input shaft on the planet carrier of planet row, is connected with power output shaft on the ring gear of planet row wear to be equipped with generator, its characterized in that on the engine input shaft: the output shaft of the generator in the gearbox body is provided with a driving gear which is meshed with a driven gear arranged on a locking shaft in the gearbox, the driven gear is provided with a combination tooth, the locking shaft is sleeved with a fixed combination tooth fixed on the gearbox body, the fixed combination tooth and the driven gear are both hung and connected through a synchronizer, and the locking shaft is provided with an oil pump.
The invention has the advantages and beneficial effects that:
1. this integrated form thoughtlessly moves gearbox with motor locking and pump oil function mainly is applied to the thoughtlessly moves gearbox of taking generator, realizes the locking of generator and breaks away from the function to realize opening of electricity generation oil pump function simultaneously and opening and stop, improve the life of generator locking structure, realize the integration of generator locking function and pump oil function, raise the efficiency, compact structure, reduce cost. According to the invention, a pair of gears (matching of the driving gear and the driven gear) is used for replacing a plurality of groups of friction pairs, so that the transmission efficiency is improved, the abrasion in the gearbox can be reduced, and the assembly cleanliness is improved; the locking function and the auxiliary pump function are integrated, the structure is compact, the cost is reduced, and the oil pumping function during power generation during parking is realized.
2. The integrated hybrid transmission case has the advantages of improving the efficiency of the transmission case, ensuring the cleanness in the transmission case, prolonging the service life of an oil pump, reducing the maintenance cost and being easy to realize, along with scientific and reasonable structural design and higher innovativeness and the functions of motor locking and oil pumping.

Detailed Description
The present invention is further illustrated by the following specific examples, which are intended to be illustrative, not limiting and are not intended to limit the scope of the invention.
The utility model provides an integrated form thoughtlessly moves gearbox with motor locking and pump oil function, includes gearbox body 4 this internal planet row that is provided with of gearbox is connected with the engine input shaft on the planet carrier of planet row, and this engine input shaft is connected with engine 1, is connected with power output shaft on the ring gear of planet row, and this power output shaft is connected with output flange 6, wears to be equipped with driving motor 5 on power output shaft the last generator 2 that wears to be equipped with of engine input shaft, its innovation part lies in: the output shaft of the generator in the gearbox body is provided with a driving gear 3, the driving gear is meshed with a driven gear 7 arranged on a locking shaft in the gearbox, the driven gear is provided with a combination tooth, the locking shaft is sleeved with a fixed combination tooth 9 fixed on the gearbox body, the fixed combination tooth and the driven gear are both hung through a synchronizer 8, and the locking shaft is provided with an oil pump 10.
The working principle is as follows:
when the engine directly drives the working condition, the engine transmits rotating speed torque, the synchronizer is simultaneously hung in the driven gear with the combination teeth and the fixed combination teeth, the fixed combination teeth are fixed with the box body, the driving gear is locked, the locking function of the generator is realized, the output flange outputs the rotating speed torque, and the oil pump does not work at the moment;
when the engine is stopped to generate electricity, the engine transmits rotating speed and torque, the output flange is static, the synchronizer is completely combined with the driven gear with the combined teeth simultaneously and is separated from the fixed combined teeth, the electricity generation function of the generator is realized through the driven gear and the driving gear, and the oil pump works at the moment.
The bench test and the road test of the prototype have been completed at present, the parking power generation and the direct-drive working condition transmission efficiency can be effectively improved, the cleanliness is improved, and the purchase cost and the maintenance cost of the whole power assembly are greatly reduced.
