Description
Technical field
Power cannot be interrupted when the present invention relates to the road vehicles such as passenger car, commercial vehicle field and needing towage
Off roader field, especially with regard to a kind of dynamic power shift gear box system of hybrid power parallel connection bi-motor.
Background technique
Existing vehicle drive system is divided into manual transmission, the uninterrupted automatic gear-box of power, hydraulic press by gear shift mode
Tool stepless speed changing case (HMCVT).
1. the uninterrupted automatic gear-box of vehicle power
Refer to vehicle driving shift speed change during, internal combustion engine to driving wheel power it is unbroken under the conditions of, the shift of completion
Process；Knot is passed through when required gear converts as gear using multi-disc wet clutch, brake, multiple rows of planetary mechanism
Splitting or integrating realizes the uninterrupted gear shift of power in vehicle load traveling, solves manual change from, the different planet row component of braking
When fast casing working the problem of parking shift, reduces employee's operation intensity, improves manipulation comfort and operating efficiency.Power is not
Interruption fluid drive gearbox internal-combustion engine rotational speed is directly related with car speed, and changes in vehicle speed causes internal-combustion engine rotational speed to change
Range is big, and internal combustion engine cannot work in the range of speeds stabilized the economy at one, and IC engine oil consumption is high, discharge is poor, vibration abrasion
Greatly.Meanwhile some vehicles due to job requirements it is more, numbers of gear steps is more, the clutch quantity and ratio that this kind of gearbox designs need
There are many example valve, and due to consistency, the gearshift performance of the type gearbox, which need to raise test-object in dedicated delivery test platform, to be determined, with
Using the time growth, clutch abrasion increase, shift control the time changed, ride comfort be deteriorated, generate shift punching
It hits.Currently, import is grasped and relied primarily on to the technology of these systems by offshore company substantially, gearbox designs complexity, price
High, price reduction hardly possible, maintenance cost are high.
2. hydraulic machinery infinitely variable transmission (HMCVT)
The gearbox is made of hydraulic plunger pump/motor/multiple rows of planetary mechanism/wet clutch and brake, main
Wanting advantage is: by planet row to internal combustion engine power dividing at two power routes, one is mechanical output route, and power is direct
It is transmitted to transmission input shaft；One is hydraulic power route, after machine-liquid-machine power conversion process, with transmission input shaft
Realize the confluence of whole power；By power dividing, confluence principle, realize gearbox torque, revolving speed according to car speed with lead
Gravitation requires automatically continuously variation, guarantees the tractive force and rate request when vehicle speed variation.
The gearbox (HMCVT) realizes the stepless automatic variation of vehicle gear box, and employee's manipulation strength is low, operating comfort
Good, operating efficiency, quality are high；Since internal-combustion engine rotational speed, torque are full decoupled (uncorrelated) to vehicle speed, tractive force, internal combustion
Machine can be stable work in low oil consumption region, shake it is small, discharge.
High pressure Variable plunger pump/motor, proportioning valve used by the gearbox (HMCVT) etc. belongs to precise hydraulic couple,
It is very high to assembling clean degree, being required using cleannes, maintenance cleannes, need specific hydraulic fluid, use and maintenance cost

Change range is big, and internal combustion engine cannot work in the range of speeds stabilized the economy at one, and oil consumption is high, discharge is poor, vibration is worn greatly.
(2) there are many clutch quantity and proportioning valve quantity that the gearbox designs need, with the increase of use time, from
Clutch abrasion increases, and the speed Control time is changed, and ride comfort is deteriorated, and generates shift shock.
(3) traditional power manual transmission system is single power route step type transmission, realizes that super creeper gear is (ultralow
Speed), to add many complicated deceleration trains.Also, it can not achieve stepless transmission when key operation, that is, theoretically cannot
It is matched to and the optimal travel speed of work tool
(4) currently, import is grasped and relied primarily on to the technology of these systems by offshore company substantially, the gearbox price
High, price reduction hardly possible, maintenance cost are high.
2. hydraulic machinery stepless speed changing case (HMCVT) realizes the universe variable speed system being made of 4-6 shelves
System, operating efficiency is high, and manipulation comfort is good, and internal combustion engine output is decoupled with vehicle load, speed, and internal combustion engine even running is in low oil
Between consumption, Low Emission Zone；Its disadvantage are as follows:
(1) mechanical variable speed system of 4-6 gear composition is by multiple rows of planetary mechanism and 4-6 wet clutch or braking
The gear that device is constituted, structure is complicated, and parts machining is with high requirements and high cost.
(2) the hydraulic power separate system being made of hydraulic precision pair, degree clean to assembly use cleannes, maintenance
It is very high to safeguard that cleannes require, needs specific hydraulic fluid, use and maintenance cost is high.
(3) since the technology of these systems is grasped by offshore company substantially, product relies primarily on import, and cost is very high, drops
Valence is difficult.
Above-mentioned conventional gearbox only has an internal combustion engine list power route, to pursue starting acceleration performance, needs using big
Displacement internal combustion engine, purchase cost increases and operation is less economical.
The information disclosed in the background technology section is intended only to increase the understanding to general background of the invention, without answering
When being considered as recognizing or imply that the information constitutes the prior art already known to those of ordinary skill in the art in any form.
