In actual use, gear train 22 limit machine power connection, with from power transmission component 17 transmit energy or
Transfer energy to power transmission component 17.More specifically, machine power connection is limited by sun gear 47.
When starting and running caterpillar 1 with low travel speed (being up to about 5km/h), control device 10 is acted on
Actuation means component, so that the power from internal combustion engine 15 is nearly or completely supplied to motor 30, only by fraction
It is supplied to mechanical component 23, or is not supplied to mechanical component 23 completely.More specifically, control device 10 acts on actuation means
36 are applied to the resistance torque of sun gear 47 to adjust by motor 30.Motor 31,32 from motor 30 receive electric power, and via
The corresponding corresponding driving wheel 5 and 6 of mechanical power transmission means 26 and 27 pair is provided with power.To be optimized by motor 31 and 32
The performance and energy consumption of caterpillar 1, motor 31 and 32 provide high torque (HT) at low engine speed, and allow internal combustion engine 15 with
The travel speed of caterpillar 1 is operating independently, to reduce energy consumption of vehicles.At high travel speed (about 25km/h),
Control device 10 acts on actuation means component, so that the kinetic energy from internal combustion engine 15 is nearly or completely assigned to machine
Fraction is only assigned to motor 30, or is not assigned to motor 30 completely by tool component 23.More specifically, control device 10 is made
For actuation means 36, to adjust the resistance torque for being applied to sun gear 47 by motor 30, so that internal combustion engine 15 is main
Power is provided with to driving wheel 5 and 6 via gear train 22 and mechanical component 23.That is, the power from internal combustion engine 15 is straight
It connects and is supplied to driving wheel 5 and 6, without further energy consumption.With the speed between high travel speed and low travel speed, control device
10 act on actuation means component, with according to the setting equation for the travel speed for considering caterpillar 1, and in mechanical component 23
The power from internal combustion engine 15 is shared between motor 30.The setting equation, for example, it may be index power is shared, thus directly
The shared increase of power for being supplied to mechanical component 23 is connect, therefore when the travel speed of caterpillar 1 increases, is supplied to motor
30 power is shared exponentially to be reduced.
By another example, which can be direct power in proportion and shares, and thus direct supply to mechanical structure
The power of part 23 is shared to be increased, therefore the power for being supplied to motor 30 is shared straight with the increase of the travel speed of caterpillar 1
It connects and proportionally reduces.
In other words, on startup, driving wheel 5 and 6 is mainly provided with power by motor 31 and 32, also, at high speeds, main
Power is provided with by mechanical component 23, that is, power is directly provided with by internal combustion engine 15, is converted without power.At moderate speed, work as speed
When increasing from starting to maximum speed, reduced by the power that motor 30 extracts, and increased by the power that mechanical component 23 extracts,
Therefore less power is supplied to motor 31 and 32, and supplies more power to mechanical component 23.It is important to note that
It is dynamic by mechanical component 23 and 31,32 pairs of supplies of driving wheel 5 and 6 of motor in most of speed range of operation of caterpillar 1
Power, therefore power transmission component 17 and machine power transmission assembly 16 are along at least part of machine power transmission assembly 16
" parallel " operation.
Therefore, power transmission component 17 and machine power transmission assembly 16 simultaneously or alternately transfer energy to drive
Driving wheel 5 and 6.More specifically, at high speeds, for the caterpillar 1 in traveling, power transmission component 17 is substantially idle；
Under the low speed, machine power transmission assembly 16 is at least partly idle；Also, at moderate speed, machine power transmission assembly 16
It is simultaneously movable with power transmission component 17.Motor 31 and 32 can be operated independently to control the turning of caterpillar 1.
Under the low speed, it when mainly transmitting power by power transmission component 17, (is especially caused by control actuation means component
Dynamic device 36 and control device 10 37) control turning, to change the rotor speed of motor 31 relative to the spinner velocity of motor 32
Degree.For example, control device 10 controls actuation means 37 and/or actuation means 38, in order to turn right with the rotor relative to motor 32
Speed reduces the spinner velocity of motor 31, and vice versa.Mainly it is provided with the middling speed of power by mechanical component 23 in driving wheel 5 and 6
Or under high speed, the control device 10 by acting on actuation means 36 and 37 controls turning, so that motor 31 or 32 is used
Make generator, that is, kinetic energy is extracted from mechanical power transmission means 26 or 27, this depends on being to need to turn right or turn left, from
And reduce the revolving speed of axle 24 or 25.
By the power supply generated by motor 31 or 32 to motor 30, motor 30 generates kinetic energy and via sun gear 47
Kinetic energy is supplied to gear train 22.
In an alternative arrangement of the utility model, when cornering, control device 10 acts on motor 32 or 31, this
Sample makes it be used as motor, that is, perhaps 26 supplies kinetic energy and by the production of motor 31 or 32 to mechanical power transmission means 27
Raw electric power powers to motor 32 or 31.In such cases, by only caused very small by the loss of parasitic Joule effect
Power dissipation execute turning, without other power dissipations, consider the kinetic energy on the one hand extracting and on the other hand supplying, from
And the efficiency relative to known technology enhancing caterpillar 1.
In an alternative arrangement of the utility model, when cornering, variable resistance 41 makes to be produced by motor 31 or 32
Raw electric power dissipation.
When making caterpillar 1 move backward, control device 10 acts on actuation means component, so that will come from internal combustion
The power of machine 15 is all supplied to motor 30, is not supplied to mechanical component 23；And it is delivered power on transmission line of electricity 35
Motor 31 and 32, therefore driving wheel 5 and 6 is only provided with power by power transmission component 17, especially is provided with moving by motor 31 and 32
Power.
In an alternative arrangement of the utility model, axis 21 (is shown by the dashed box) equipped with commutator 50 in Fig. 2,
It is designed as making the rotation of axis 21 to invert, so that, when reverse travel, lead to also in a manner of identical with when moving forward
It crosses axis 21 and kinetic energy is transmitted to driving wheel 5 and 6.
