Abstract

The invention discloses a split-type transmission driving shaft which comprises a driving shaft A 9 and a driving shaft B 5, wherein the driving shaft A 9 and the driving shaft B 5 share a coaxial line, are separated or combined by a separation mechanism 6, and can be equipped with transmission gears and gear shift mechanisms and transmit power to an output shaft. When the separation mechanism 6 performs separation, the driving shaft A and the driving shaft B can respectively or simultaneously output power to a driven shaft through the transmission gears and the gear shift mechanisms which are mounted on the driving shaft A and the driving shaft B respectively; and when the separation mechanism 6 performs combination, the driving shaft A and the driving shaft B are combined into a whole, power can be transmitted between the two shafts, and power also can be transmitted to the driven shaft through the transmission gear which is mounted on any one of the driving shaft A and the driving shaft B. The split-type transmission driving shaft has the benefits that the structure is simple, the transmission path is flexible, the technology of the traditional gearbox is inherited well, and the split-type transmission driving shaft can be widely applied to a double-shaft type gearbox and an intermediate-shaft type gearbox and a multi-intermediate-shaft type gearbox.

Description

Split type transmission drive shaft

[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, speed changer and the axle thereof of load.

[background technique]

At present, because 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 the electric vehicle hybrid vehicle.Pure electric automobile has the advantage of energy-saving and environmental protection, has obtained at present the attention of main automobile production enterprise gradually.Electric vehicle is on the basis of orthodox car, and motor is replaced by motor, and the motor vehicle that energy-storage system, control system and other auxiliary systems such as electrokinetic cell form are installed.Motor has characteristics such as volume is little, in light weight, running is steady, efficient height with respect to conventional engines.But current stage used for electric vehicle electrokinetic cell also exists specific power, problem that specific energy is little, and in most of occasion, pure electric automobile can't replace the traditional combustion engine vehicle fully.Hybrid vehicle can use the vehicle class of the electric energy of cleaning to begin to be widely used as the long mileage and the electric vehicle energy-saving and environmental protection that have the traditional combustion engine vehicle concurrently.Also have reliability, Economy and the reduction manufacture cost etc. of some vehicles in order to guarantee vehicle simultaneously, have plural power source.These vehicles of some special purpose vehicles, engineering machinery, super sized type vehicle, special safety vehicle etc. that for example have assistant engine all need the power with two above different dynamic sources to be coupled together, and drive system---the dynamic coupling system of vehicle jointly or respectively.The requirement of dynamic coupling system is the power of plural power source output to be delivered on the output unit (as wheel etc.) respectively separately, can be delivered to the power of plural power source output on the output unit simultaneously again; And for motor vehicle driven by mixed power except above-mentioned functions, also the power of power source output must be delivered on the another one power source (generally being motor), and guarantee simultaneously not to be passed on the output unit, with functions such as the generatings that realizes stopping.

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, automobile such as general fertile Lan Da;

2 adopt angle transmission gear shift device.The typical case uses and comprises Nan Che group hybrid power passenger car;

3 adopt coaxial coupling, are about to motor and are installed 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 to Gear Processing required precision height, lubricated difficulty etc.

It is fixing that mode 3 exists two power source speed to cooperate, 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 provides a kind of transmission drive shaft that the power flexible communication of two power sources can be arrived output shaft, simultaneously can also take full advantage of existing speed changer manufacturing mechanism, technology, part, reducing the first input cost of system to greatest extent, 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: transmission drive shaft is divided into two-part, comprises 9 driving shaft A and 5 driving shaft B, two-part coaxial line.Use 6 its disengagement or joint between driving shaft A and the driving shaft B.

On driving shaft A and the driving shaft B driving gear and gearshift can be installed, to the output shaft transferring power.

Driving shaft A and driving shaft B can use separately independently shaft supporting structure, also can the common shaft supporting structure, and can also between diaxon, use bearing to support mutually.

When 6 its disengagement, driving shaft A and driving shaft B can distinguish or go up driving gear by dress to the driven shaft outputting power by axle separately simultaneously; 6 separating mechanisms in conjunction with the time, driving shaft A and driving shaft B just are combined into an integral body, can transferring power between the diaxon, also can be by both any one go up driving gear of installing to the driven shaft transferring power.

The invention has the beneficial effects as follows, simple in structure, drive path is flexible, and is good with traditional gearbox technology inheritance, can be widely used in two-axis gearbox, middle shaft type gearbox and many in the middle of in the shaft type gearbox.

[embodiment]

To introduce embodiment by reference to the accompanying drawings, actual embodiment is not limited thereto example below.

9 driving shaft A and 5 driving shaft B in the accompanying drawing 1, two-part coaxial line.Use 6 its disengagement or joint between driving shaft A and the driving shaft B, between 9 driving shaft A and 5 driving shaft B, used bearing to do mutual support, but according to application requirements, also can use sliding bearing or other supporting way to solve the support problem of diaxon.

In the speed changer a lot of transmission arrangements that used jack shaft are arranged now, accompanying drawing 2 is exactly wherein a kind of.When the split type transmission drive shaft of the present invention is applied on the countershaft transmission, can substitute the jack shaft of former speed changer.As shown in Figure 3, split type driving shaft substitutes former jack shaft fully, and the branch body position can be between any two speed change gear pairs.Simultaneously, adjust the speed ratio of each gear pair, can optimize the operating characteristic of two power sources and load, improve operational efficiency.

When there being one can be to when reversing in the power source, can cancel reverse gear on the basis of accompanying drawing 3, become the forward gears gear, the characteristics of utilizing a power source to reverse realize the car-backing function of single power source, as shown in Figure 4.Such benefit is under the situation that the speed changer overall dimension does not increase, and can obtain a velocity ratio more.

As shown in Figure 4, gearshift also can be installed on the split type driving shaft.
