Abstract
The invention discloses a kind of a11wheel drive transfer gear electric control gear, including data processing unit, the data acquisition unit for signals collecting being all connected with data processing unit, power supply and power output unit.The present invention can realize more preferably, safely switch transfer gear each state, extend drive system service life, and dynamic property match meet transfer gear use requirement.
Description
Technical field
The invention belongs to auto electric field, be specifically related to a kind of a11wheel drive transfer gear electric control gear.
Background technology
Because automobile travels operation under different road conditions, especially in the case of road conditions is severe, general drives
On ejector half formula automobile, vehicle is climbed when, its power cannot realize effectively distributing to propons so that vehicle climbing is tired
Difficulty, the attachment coefficient on tire and ground can not meet driving requirements, thus increase the power consumption of car load and power train parts and
Tire wear.
For increasing change speed gear box output moment of torsion (change gear ratio) further, play reduction of speed and increase the effect turned round, therefore transfer gear
It is provided with high and low shift, it is possible to expand transmission when gear number when travelling in the area in hardship.Meet under different operating mode simultaneously
Use condition, is additionally provided with propons clutch, can be divided according to a certain percentage by transfer gear by the power that variator exports
It is fitted on each drive axle.
When overload of vehicle, damage for preventing back axle and jackshaft overload, low or first gear power should be made to be shared by forward and backward bridge,
Ensure that automobile possesses enough pull strengths.When good road traveling, propons power to be cut off, transfer gear is arranged on
On top gear, thus improve fuel economy.In the case of there is no a11wheel drive transfer gear electric control gear, on the one hand cannot have
Effect realizes change speed gear box reduction of speed and increases and turn round and transfer gear is assigned to the effect of each drive axle according to a certain percentage；On the other hand operate numerous
Trivial, efficiency is low, error-prone.
Summary of the invention
The problem existed for above-mentioned prior art, the present invention provides a kind of a11wheel drive transfer gear electric control gear, permissible
Realize switching each state of transfer gear more preferably, safely, extend the service life of drive system, and match in dynamic property satisfied
Transfer gear uses requirement.
For solving the problem that above-mentioned prior art exists, the technical scheme that the present invention takes is: a kind of a11wheel drive transfer
Device electric control gear, including data processing unit, the data acquisition unit for signals collecting being all connected with data processing unit,
Power supply and power output unit.
Described data acquisition unit comprise high and low shift converted input signal switch, propons clutch input signal switch and
CAN communication interface.
Described data processing unit, for the data collected carrying out computing, comparing, leads to according to computing, comparative result
Each road power is exported by overpower output unit.
A11wheel drive transfer gear electric control gear of the present invention, can effectively realize transfer gear height gear and propons
The conversion of drive pattern.Simultaneously for avoid because of transfer gear change to low or first gear time, output moment of torsion is relatively big, in avoiding, back axle overload,
Controlling device for this interlock logic to be had, this device uses CAN interface, can and vehicle body and engine in situ control between network
Carry out data and information communication.Can effectively be realized the logic control of gas circuit each to transfer gear by this control device, take into account
From safety perspective, transfer gear is non-first to be connected propons and must not hang up low or first gear, non-first exits low or first gear, before must not taking
Bridge, for not damaging the combination gear of transfer gear, when high and low shift is changed, it is necessary to is in halted state or close to walking speed at vehicle
Carry out when spending, and need be kept completely separate clutch or variator is linked into neutral, gearshift can be handled.Transfer gear engages (de-
Open) propons time, it is necessary to carry out after parking, and variator hung neutral, can operate.Consider wanting of above-mentioned manipulation
Asking, this control device is when driver's faulty operation, and the consequence that maloperation can be made to produce lost efficacy, and reduced damage to greatest extent
Lose, avoid abrasion in real time or break the gear of drive system, thus extending its life-span.

Detailed description of the invention
Transfer gear described further below controls the implementation that device constitutes and controls device logic.
Embodiment 1
A kind of a11wheel drive transfer gear electric control gear as shown in Figure 1, including major control data processing unit, all with data at
The data acquisition unit for signals collecting, power supply and the power output unit that reason unit connects.Described data acquisition unit
Comprise high and low shift converted input signal switch, propons clutch input signal switch and CAN communication interface；Described data process single
Unit, for the data collected carrying out computing, comparing, according to computing, comparative result by power output unit by each road
Power exports.The circuit theory diagrams of each several part are as shown in Fig. 2-Fig. 6.
Transfer gear described in embodiment 2 embodiment 1 controls device and implements control method
A. high-grade and low mode is changed:
Pressing high and low shelves permutator button, when corresponding top grade or low-grade display lamp are lighted, transfer gear is i.e. in
Top grade or Low gear state, now unclamp manipulation switch, and transfer gear is in top grade or Low gear state.
By corresponding on-off control electromagnetic valve break-make, high and low shift gas circuit, to realize the conversion of high and low shift, top grade is to low grade
As it is shown in fig. 7,1 mouthful of air inlet, pressure F promotes two pistons of size to be moved to the left to extreme position always, and piston promotes to the left and pulls out
Fork shaft, fork promotes to the left combining tooth set, and tooth set engages with power shaft and low-grade tooth simultaneously, and power is transmitted by low-grade tooth,
Transfer gear is in low-grade gear and changes to low grade from top grade.
Low grade is illustrated in fig. 8 shown below to top grade, 3 mouthfuls of air inlets, and pressure F promotes valve piston to move right to extreme position, piston
Promoting to the right fork axle, fork promotes to the right combining tooth set, and tooth set engages with power shaft and high-grade tooth simultaneously, and power is by height
Shelves tooth transmission, transfer gear is in high-grade gear and changes to top grade from low grade.When the afterbody of fork axle moves left and right push rod accordingly
Upwards pushing up, two binding posts of high and low shelves indicator light switch (normally opened) are connected.
B. the conversion between propons principal and subordinate wheel
Press propons Isolating Switch button, by electromagnetic valve control propons gas circuit, pressure pushes away piston to the right, drive fork and
Propons combines tooth set and moves right so that propons combines tooth set and engages with front output shaft and rear output shaft simultaneously, can be front and back
Output shaft is considered as an entirety, now the most dynamic output front and back.I.e. propons is in bonding state；After variator is linked into gear,
The push rod of propons indicator light switch (normally closed) is released, and propons clutch display lamp is i.e. lighted.Disconnect propons Isolating Switch button, front
The when that bridge not connecing gas, back-moving spring pushes up fork to the left, and propons combines tooth set and is not combined with rear output shaft, now propons output
Axle does not has power to export.Propons fork now withstands the push rod of propons indicator light switch, and two binding posts of display lamp do not connect
Logical.
