When the star-like brake 3 of shelves and the star-like brake 4 of low or first gear are braked, the output of gearbox locking.
More specifically, main control strategies of the invention and mode of operation process are as follows：
1st, high gear mode
When external impetus needs small speed than transmitting, controller sends instruction, the brake oil in high pressure liquid source to high pressure liquid source
Liquid enters brake pipe 6, and brake pipe 6 is transported to the inner carrier 34 of the star-like brake 3 of multiple top gears by fluid is braked simultaneously
With outer piston 35, now, the outer piston 35 of the star-like brake 3 of top gear promotes top gear star-like under the effect of high-pressure brake fluid
The external friction block 31 of brake 3 travels forward and is adjacent to the lateral surface of the brake disc 29 of the star-like brake 3 of top gear, meanwhile, it is high
The inner carrier 34 of the fast star-like brake 3 of shelves promotes the interior brake pad of the star-like brake 3 of top gear under the effect of high-pressure brake fluid
30 travel forward and are adjacent to the medial surface of the brake disc 29 of the star-like brake 3 of top gear, and then, the star-like brake 3 of top gear
Brake disc 29 is braked.
Controller keeps the star-like brake 4 of low or first gear to be in braking fluid unloading condition simultaneously, and then, the star-like system of low or first gear
The brake disc 29 of dynamic device 4 is in free rotary state.The brake disc 29 of the star-like brake 3 of top gear passes through spline pair and top gear
Star-like axle 17 connects, thus, the star-like axle 17 of top gear is braked；The star-like wheel 16 of top gear is fixedly mounted on the star-like axle 17 of top gear
On, the star-like wheel 16 of top gear is braked；Top gear it is star-like wheel 16 simultaneously with the internal messing of top gear ring gear 14, thus, top gear
Ring gear 14 is braked.
Because the brake disc 29 of the star-like brake 4 of low or first gear is in free rotary state, therefore, at the star-like wheel 25 of low or first gear
In free rotary state；The star-like wheel 25 of low or first gear and the internal messing of low or first gear ring gear 24, thus, low or first gear ring gear 24 is in certainly
By rotary state；Power passes to input shaft 6 by input flange 42, and input shaft 6 imparts power to the He of top gear sun gear 10
Low or first gear sun gear 20；Power is transmitted top gear planetary gear 11, top gear planetary gear by top gear sun gear 10 by external toothing
11 impart power to top gear ring gear 14 by internal messing；Because top gear ring gear 14 is braked, therefore, from a high speed
The power of shelves sun gear 10 passes to pivoted arm 15 through low or first gear sun gear 20.Low or first gear sun gear 20 is passed power by external toothing
Low or first gear planetary gear 21 is passed, low or first gear planetary gear 21 imparts power to low or first gear ring gear 24 by internal messing；Due to low
Fast shelves ring gear 24 is in free rotary state, and therefore, the power from low or first gear sun gear 20 is not transferred to pivoted arm 15.
Under high gear mode, the rotation speed relation of input flange 42 and output flange 43：
Z1 represents the number of teeth of top gear sun gear 10, and Z2 represents the number of teeth of top gear ring gear 14, and n1 represents input flange
42 rotating speed, n2 represent the rotating speed of output flange 43.
2nd, low gear mode
When external impetus needs large speed ratio to transmit, controller sends instruction, the brake oil in high pressure liquid source to low hydraulic source
Liquid enters the brake pipe 36 of the star-like brake 4 of low or first gear, and brake pipe 36 will brake fluid, and to be transported to low or first gear star-like simultaneously
Inner carrier 34, the outer piston 35 of brake 4.The outer piston 35 of the star-like brake 4 of low or first gear
Promote the external friction block 31 of the star-like brake 4 of low or first gear to travel forward under the effect of high-pressure brake fluid and be adjacent to low
The lateral surface of the brake disc 29 of the fast star-like brake 4 of shelves, meanwhile, the interior brake pad 30 of the star-like brake 4 of low or first gear is suppressed in height
Dynamic fluid effect is lower to be promoted the interior brake pad 30 of the star-like brake 4 of low or first gear to travel forward and is adjacent to the star-like brake 4 of low or first gear
Brake disc 29 medial surface, the brake disc 29 of the star-like brake 4 of low or first gear is braked.Controller keeps top gear star-like simultaneously
Brake 3 is in braking fluid unloading condition, and then, the brake disc 29 of the star-like brake 3 of top gear is in free rotary state.
The brake disc 29 of the star-like brake 4 of low or first gear is connected by spline pair axle 2626 star-like with low or first gear, thus, the star-like axle of low or first gear
26 are braked；The star-like wheel 25 of low or first gear is fixedly arranged on the star-like axle 26 of low or first gear.
The star-like wheel 25 of low or first gear is braked；Low or first gear it is star-like wheel 25 simultaneously with the internal messing of low or first gear ring gear 24, thus, it is low
Fast shelves ring gear 24 is braked；Because the brake disc 29 of the star-like brake 3 of top gear is in free rotary state, therefore, at a high speed
The star-like wheel 16 of shelves is in free rotary state；The star-like wheel 16 of top gear and the internal messing of top gear ring gear 14, thus, in top gear
Gear ring 14 is in free rotary state；Power passes to input shaft 6 by input flange 42, and input shaft 6 imparts power at a high speed
Shelves sun gear 10 and low or first gear sun gear 20；Power is transmitted top gear planetary gear 11 by top gear sun gear 10 by external toothing,
Top gear planetary gear 11 imparts power to top gear ring gear 14 by internal messing；Because top gear ring gear 14 is in freely
Rotary state, therefore, the power from top gear sun gear 10 are not transferred to pivoted arm 15.Low or first gear sun gear 20 by nibbling outside
Conjunction imparts power to low or first gear planetary gear 21, and low or first gear planetary gear 21 imparts power to low or first gear ring gear by internal messing
24；Because low or first gear ring gear 24 is in on-position, therefore, the power from low or first gear sun gear 20 is through low or first gear planetary gear
21 pass to pivoted arm 15.
Under low gear mode, the rotation speed relation of input flange 42 and output flange 43：
Z3 represents the number of teeth of low or first gear sun gear 20, and Z4 represents the number of teeth of low or first gear ring gear 24, and n1 represents input flange
42 rotating speed, n2 represent the rotating speed of output flange 43.
