Abstract

The invention discloses a flexible transmission gearbox. Based on an intermediate shaft type gearbox, a bearing 9 and a set of separation mechanism 8 are arranged on an intermediate shaft driven gear 10 and an intermediate shaft 6, and therefore when the separation mechanism 8 separates, an input shaft 1 or the intermediate shaft 6 can respectively establish a power transmission path alone with an output shaft 5 and can transmit power to the output shaft at different speed ratios at the same time; when the separation mechanism 8 connects, the input shaft 1 or the intermediate shaft 6 can transmit the power to the output shaft at the same speed ratio at the same time and can conduct transmission path change under the condition that the power transmission is not interrupted through automatic control. The flexible transmission gearbox has the advantages of being capable of achieving most flexible dynamic coupling path by merely slightly changing part structure of a traditional gearbox, good in process inheritance compared with the traditional gearbox, and capable of being widely used in various power devices such as a car, a railway car, a ship, engineering machinery, agricultural machinery and the like.

Description

A kind of flexible transmission speed variator

[technical field]

The present invention relates to that power transmission system, particularly gear subtract, speed change gear, motor vehicle driven by mixed power, have three and above power source and retarder, the speed changer of load, can be widely used on the various power equipments such as automobile, rail vehicle, boats and ships, engineering machinery, farm machinery.

[background technique]

At present, due to the pressure of energy-saving and emission-reduction, automobile energy-saving reduces discharging the standard increasingly stringent.In order to reduce the energy consumption of vehicle, developed the numerous new vehicle system that comprises hybrid vehicle.Hybrid vehicle can use the vehicle class of the electric energy of cleaning to begin to be widely used as having the long mileage of traditional combustion engine vehicle and electric automobile energy saving, environmental protection concurrently.Also have simultaneously reliability, Economy and the reduction manufacture cost etc. of some vehicles in order to guarantee vehicle, have plural power source.For example have some special purpose vehicles, engineering machinery, super sized type vehicle, special safety vehicle of assistant engine etc.These vehicles all need one with the power coupling in two above different dynamic sources, jointly or respectively drive system---the dynamic coupling system of vehicle.The requirement of dynamic coupling system is the power of plural power source output to be delivered to separately respectively on output unit (as wheel etc.), can be delivered to simultaneously the power of plural power source output on output unit again; And for motor vehicle driven by mixed power except above-mentioned functions, also must be with the power of a power source output, be delivered on another one power source (being generally motor), and guarantee simultaneously not to be passed on output unit the functions such as generating of stopping with realization.

But current can realize above-mentioned functions the dual power source dynamic coupling system, mainly comprise following several form:

1 adopts the planetary pinion coupled modes.The typical case use comprise Toyota general sharp this, the automobile such as general fertile Lan Da;

2 adopt the angle transmission speed variator.The typical case uses and to comprise Nan Che group hybrid power passenger car;

3 adopt coaxial coupling, are about to motor and are arranged on the motor Transmitted chains, rely on plural clutch to realize different output modes.

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, and is bad with the production technology inheritance of existing vehicle drive system, needs used device, mould etc. again.

Mode 2 adopts bevel gear tooth system high to the Gear Processing required precision, lubricated difficulty etc.

Mode 3 exists two power source speed to be fixed, and is difficult to bring into play the problems such as optimum-curve for operation of each power source

The present invention can solve the problems referred to above of dual power source dynamic coupling system.

[summary of the invention]

The technical problem to be solved in the present invention be to provide a kind of can be with retarder or the speed changer of the power flexible communication of three above power sources or load, simultaneously can also take full advantage of existing speed changer manufacturing mechanism, technique, part, reducing to greatest extent the first input cost of system, and the simplification of implementation structure.

In order to solve the problems of the technologies described above, the technological scheme that the present invention takes is: comprise 1 input shaft, 2 one shaftgears, 3 gearshifts, 4 power shift gears, 5 output shafts, 6 jack shafts, 7 shells, 8 separating mechanisms, 9 bearings, 10 counter shaft driven gears.

Be exactly briefly on the basis of intermediate shaft type speed changer, a bearing and one group of separating mechanism are installed between 10 counter shaft driven gears and 6 jack shafts.Like this, when 8 its disengagement, 1 input shaft or 6 jack shafts can be respectively be set up power transmission path with 5 output shafts separately, also can be simultaneously with different speed ratios to the output shaft transferring power; When 8 separating mechanisms engage, 1 input shaft or 6 jack shafts can be simultaneously with identical speed ratio to the output shaft transferring power, can also realize in the not transfer route conversion under interrupt condition of transmission of power by automatically controlling.

The invention has the beneficial effects as follows only a small amount of design of part that changes traditional speed changer, just can realize power coupling path the most flexibly.

According to application requirements, a kind of flexible transmission speed variator of the present invention can be applied to multi-countershaft transmission, jack shaft with bearing and separating mechanism of every increase, just can introduce a power source or load more, can realize power transmission route alone or in combination between each power source and load.The present invention can be widely used on the various power equipments such as automobile, rail vehicle, boats and ships, engineering machinery, farm machinery.
