Background technique
The research of domestic and international endless-track vehicle hybrid transmissions be concentrated mainly on two-side motor independently drive pattern with
And double-current zero differential speed type.
Two-side motor independently drives type structure simple, and two driving motors respectively drive two sides crawler belt, straight operating condition control
The speed of two sides motor processed is consistent;When steering, the rotational speed difference by controlling two sides motor is realized.Since endless-track vehicle minor radius turns
To when inner track can generate steering reflux power, to make full use of the Partial Power, interior outside driving motor must have very
Big power capacity makes to turn to reflux power by inside electric power generation, feeds back to outside motor using electric system.=this drive
Ejector half formula needs motor to have very big power grade, additionally increases the volume and weight of transmission system, also increases to electricity
The technical requirements of machine.
Double-current zero differential speed type transmission device overcomes the technical disadvantages that two-side motor independently drives, and uses remittance in steering procedure
Planet row and zero axle are flowed, steering confluence power is mechanically efficiently solved from inner track and is transmitted to outer track.Directly
It sails motor and completes straight propulsion, steering motor is responsible for steering power, respectively applies its duty.But shortcoming is that straight turns to electricity in the process
The power of machine cannot utilize, and the power of straight motor cannot utilize in same steering procedure, and it is idle that there are powers of motor, be easy to make
It is bigger than normal at transmission device overall dimension and weight.
The E-X-Drive endless-track vehicle mixed power plant referred in BAE house journal of Britain (US7326141B2) is by two
Platform straight motor, a steering motor and a power coupling mechanism composition.When small radius steering, two straight motors and one
Platform steering motor is completed jointly, and the steering reflux from inner track to outer track is effectively delivered by power coupling mechanism
Power;Therefore the power of steering motor can be the half or so of double-current zero differential speed type steering motor power.Medium turning radius arrives
The operating condition of big turning radius, is individually completed by steering motor, high-power straight when straight motor only is responsible for running at high speed at this time
It promotes.This style of hybrid transmissions realize straight and couple with the part of steering motor power, more double-current homodyne
Fast formula effectively improves the power utilization of motor.
The endless-track vehicle that several two-side motor drivings have both standby turning function is described in patent CN102229319A to mix
Actuating unit solves two-side motor and independently drives the disadvantage high to traction electric machine requirement, volume weight is big, realizes and turn
It is coupled to the power of motor and straight motor, two motors complete straight and turning function jointly, improve the power of motor
It utilizes, the volume and weight of transmission device can be further decreased.But power coupling mechanism is complicated, needs 3~4 planet rows mutual
Connection forms two degrees of freedom planetary mechanism, and internal component is easy to produce circulating power in endless-track vehicle steering procedure, influences
The raising of transmission efficiency.
Series hybrid-power transmission device is suitable for operating condition and frequently changes, frequent start and stop occasion, can be by optimizing engine
Operating point, reach the optimal of system effectiveness.Parallel hybrid powertrain device reduces the loss of energy conversion, more suitable for
Constant ride operating condition, it is optimal to reach gear efficiency.
