The operation principle of the present invention is:
Each gear, by input brake I and final stage planetary carrier brake II collaborative work, makes each shelves planetary mechanism work
In active state or be in the servo-actuated state of low speed: input brake is opened, final stage planet carrier closes, and these shelves have the initiative shape
State；Input arrester close, final stage planet carrier opens, and these shelves are in the servo-actuated state of low speed.
All gear clutchs are opened, and when the input brake of some gear is opened, remaining gear input is braked
Device closes, and this gear final stage planetary carrier brake closes, and remaining gear final stage planetary carrier brake is opened, and this gear clutch closes
Closing, this gear planetary mechanism works, and remaining gear planetary mechanism enters the servo-actuated state of low speed, and this gearshift output one turns
Speed；When second gear needs work, the clutch of work at present gear is opened, and the input brake of work at present gear is closed
Closing, the final stage planetary carrier brake of work at present gear is opened, and the input brake of second gear is opened, second gear
Final stage planetary carrier brake Guan Bi, the clutch Guan Bi of second gear, the work of second gear planetary mechanism, remaining gear
Planetary mechanism enters the servo-actuated state of low speed, the another kind of rotating speed of this gearshift output；By that analogy.
When each shelves speed reducing ratio difference is not big especially, and any one gear inputs, and remaining gear is servo-actuated, all servo-actuated shelves
When rotatable parts all allow rotating speed less than it, the input brake of all gears can be uneasy with final stage planetary carrier brake
Dress.
Can also selectively carry out according to the servo-actuated rotating speed of each shelves brake is installed, it may be assumed that need to install the shelves of brake
Brake is just installed in position, it is not necessary to the gear installing brake is not installed.
At each shelves input, input brake is installed, brake is installed on each shelves final stage planet carrier simultaneously, solves
The problem that follower gear rotating speed is the highest.As: the gear ratio of first grade is 3, and the gear ratio of second gear is: i=134-1=28560 or
Bigger, when first grade actively time, although the gear ratio of second gear is very big, but second gear to remain able to low speed servo-actuated！Need a certain
The gear ratio of individual gear becomes much larger, as long as increasing the progression of this grade of planetary reduction gear, and the footpath of gearshift after increase progression
Need not strengthen to size, its axial dimension is the superposition of planetary mechanism axial dimension at different levels.
The invention have the benefit that
Thering is provided a kind of many grades of variable transmission mechanisms of coaxial line Gear Planet Transmission, this mechanism is capable of many grades of coaxial line Gear Planet Transmission
Speed change, and the planetary mechanism of idle shelves is in the servo-actuated state of low speed；The scope that realizes of each grade of gear ratio becomes much larger, such as:
When these shelves are made up of Pyatyi Closed planetary transmission, gear ratio can reach i=134-1=28560, even the biggest transmission
Ratio, after increasing input brake and final stage planetary carrier brake, the planetary mechanism of this grade also can low speed servo-actuated, when progression increases
Added-time, gear ratio can be bigger；The gear ratio needing some gear becomes much larger, as long as increasing the progression of this grade of planetary reduction gear
, after increasing progression, the radial dimension of gearshift need not strengthen, and its axial dimension is planetary mechanism axial dimensions at different levels
Superposition, compares many grades of gears of many parallel axes, saves substantial amounts of space；This gearshift is an independent gear shift unit,
The relatively independent design of each shelves, is increased or decreased gear easy, is the axially stacking of a kind of each shelves planetary mechanism or minimizing, easily real
Existing modularized design, forms many grades of variable transmission mechanisms of combination coaxial line Gear Planet Transmission, i.e. improves design efficiency, improve again
Production efficiency；Multiple clutch positions of this mechanism are all at input, and structure easily realizes；Expand the application neck of planetary mechanism
Territory.
