The present embodiment is three gear hydraulic transmission systems, is a gear bottom gear, coupling device I when 24 oil-filled work of torque-converters
It is speed gear in two gears when 22 oil-filled work, keeps off top gears, 34 oil-filled work of brake for three when II 32 oil-filled work of coupling device
It is damped condition when making.
The course of work of the present embodiment is as follows：Control system detects car speed, and carrying out gear according to scheduled speed cuts
It changes.Input shaft 1 is power intake, and output shaft 6 is II 12 meshed gears I 26 of gear on power output end, with input shaft 1
It is rotated with gear IV 37, drive pump impeller shaft I 23 and pump impeller shaft II 33 and then drives coupling device pump impeller 221 and converter pump 241
Rotation, when vehicle launch and low speed operation, mechanical energy is transformed into high-voltage high-speed liquid energy by 24 oil-filled work of torque-converters, then
Respective driven wheel turbine is passed to, is at this time the oil-filled work of a gear；When vehicle drives to moderate speed range, control system is cut
It changes oil road so that I 22 oil-filled work of coupling device, while 24 oil extraction of torque-converters are at this time the oil-filled work of two gears；Work as locomotive operation
To II 32 oil-filled work of coupling device when higher speed range, while I 22 oil extraction of coupling device, it is the oil-filled work of three gears.Due to power
Transmittance process in, the number of teeth of gear III 36 is more than the number of teeth of reverse transition gear 4, is speed increasing gear pair, therefore output shaft 6 can
To be rotated with higher speed, the work of three gears is realized.In each gear hydraulic power unit handoff procedure, oil extraction with it is oil-filled simultaneously into
Row ensures that tractive force does not interrupt.When hydraulic braking, the equal oil extraction of all traction hydraulic power units does not work；The oil-filled work of hydraulic brake
Make, realizes the braking of vehicle.It is identical with defeated steerings is entered that forward direction described in the present embodiment is that output is turned to, be reversed output steering and
Input turns to opposite.
Each gear work of traction working condition is as follows：
Power transmission is realized in when 0-1 keeps off work：
It is positive：I 23- torque-converters 24- forward direction transition gear 51- proper crossovers gear 87 of input shaft 1- pump impeller shafts (change by forward direction
Engaged to mechanism clutch)-output shaft 6；
Reversely：I 23- torque-converters 24- forward direction transition gear 5- reverse transition gears 4- of input shaft 1- pump impeller shafts reversely commutates
Gear 77- output shafts 6.
Power transmission is realized in when 2 gear work：
It is positive：I 23- coupling devices of input shaft 1- pump impeller shafts, I 22- forward direction transition gear 51- proper crossovers gear 87 (change by forward direction
Engaged to mechanism clutch)-output shaft 6；
Reversely：I 23- coupling devices of input shaft 1- pump impeller shafts, I 22- forward direction transition gear 51- reverse transition gears 41- is reversely changed
To gear 77 (reversed changement clutch engagement)-output shaft 6.
Power transmission is realized in when 3 gear work：
It is positive：II 32- gears of input shaft 1- II 33- coupling devices of pump impeller shaft, III 26- reverse transition gear 41- forward direction transition teeth
Take turns 87 (engagement of proper crossover mechanism clutch)-output shaft 6 of 51- proper crossovers gear；
Reversely：II 32- gears of input shaft 1- II 33- coupling devices of pump impeller shaft, the III reversed commutating tooths of 36- reverse transition gear 41-
Wheel 77 (reversed changement clutch engagement)-output shaft 6.
When turbine output shaft rotating speed is 0, changement could work, and clutch could engage；Forward and reverse changement is not
Can work at the same time, can only the engagement of one of them clutch, communtation protection is arranged in control system accordingly.
Damped condition work is as follows:
Input shaft 1 has certain input speed, mainly provides the working oil with certain pressure for brake 34, works as vehicle
In long and steep downgrade operation or fair speed operation, vehicle control system sends out brake command, and brake 34 starts oil-filled work
Make, the kinetic energy of coming is transmitted by the gear III 36 of output shaft 6 to hydraulic axis II 3, the rotation of brake rotor 342 is driven, will transmit
The mechanical energy come is completely converted into the heat of oil, through cooling system circulating cooling.Kinetic moment is born by brake stator 341, then
It passes on shell.Because brake liquid impeller blade is top rake blade, it can hold 3-10 times bigger than identical lumen type coupling device, can realize very
Small structure size can play big brake force, be conducive to structure and arrange.Realize that the long ramp of vehicle travels at the uniform speed or quickly makes
It is dynamic.When the oil-filled work of hydraulic brake, each not oil-filled work of traction working condition hydraulic power unit.This structure brake is particularly suitable for height
Fast vehicle braking.Because liquid transmits kinetic energy, braking is steady reliable, reduces the abrasion of vehicle friction brake device, improves vehicle braking
The safety of system.Brake force is smaller when due to the brake slow-speed of revolution, need to be used in combination with vehicle foundation brake system.
