It closes, the centrifugal-block being mounted on driving shaft between driving shaft and passive axle sleeve, passive axle sleeve is connected with the input terminal of speed changer
It connects.
The clutch is the fluid torque-converter for including pump impeller, turbine, guide wheel, the power output shaft phase of pump impeller and motor
Connection, turbine are connected with the input terminal of speed changer.
The power supply of the electric truck is overhead transmission line, is engaged by pantograph with overhead transmission line, by ignition distributor and
Wire connected battery, battery are connected by controller and power supply line with motor.
The battery has lead storage battery and capacitor batteries.
The motor is two coaxial series electric motors, passes through two driving wheel phases of clutch and speed changer and left and right respectively
Transmission.
The speed changer is two-stage planet speed changer.
Brake power generating device is housed on the driving wheel.
The beneficial effects of the present invention are: becoming rigidity is driven to flexible drive, automatic speed regulation is realized, it is automatic when starting or crossing a ridge
Revolving speed is reduced, the ability of increasing traction, leaping over obstacles significantly improves, and the year-on-year rating of electric machine is greatly reduced, stable working performance
Reliably, it is not easy to put out a fire, the electric truck particularly suitable for the transport of the heavy-duties such as mine.

Specific embodiment
The total design of the present invention is: clutch is equipped between the power output shaft and speed changer of motor.Above-mentioned apparatus
Specific structure can there are many, all should belong to equivalent mechanical structure.Three kinds of embodiments are introduced with reference to the accompanying drawing:
The first embodiment: Fig. 1 describes a kind of power driving mechanism of electric truck, visible in figure: this electronic card
The power output shaft of the motor 1 of vehicle drives driving wheel 4 by speed changer 3, its main feature is that: the power output of the motor 1
Clutch 2 is equipped between axis and speed changer 3.Visible in conjunction with Fig. 2: the clutch 2 is centrifugal clutch 5.Centrifugal clutching
The driving shaft 6 of device 5 is the power output shaft of motor 1, and driving shaft 6 and passive axle sleeve 10 are clearance fit, driving shaft 8 and passive
The centrifugal-block 7 being mounted in active 8 between axle sleeve 8, passive axle sleeve 8 are connected with the input terminal of speed changer 2.
When motor 1 starts, revolving speed is smaller, and centrifugal-block 7 pulls to 6 side of driving shaft by tension spring, de- with passive axle sleeve 8
From load is minimum, and motor can smoothly start.When the revolving speed of motor 1 is higher, centrifugal-block 7 by centrifugal force effect, to
Outer movement compresses with passive axle sleeve 8 and generates enough frictional force, driving wheel 4 can be driven to rotate.
When truck transport road encounter obstacle when, 6 limited in rotation of driving shaft and reduce, centrifugal-block 7 can also return to driving shaft 6
Side enables driving shaft to continue to rotate, and motor is unlikely to put out a fire.Meanwhile driving shaft 6 is always turned with revolving speed as big as possible
It is dynamic, it compresses centrifugal-block 7 with passive axle sleeve 8 as far as possible, is equivalent to drive with same output power and alap revolving speed and drive
Wheel rotation, so that maximum drawbar pull is obtained, final leaping over obstacles.
Second of embodiment: the electric truck driving mechanism of Fig. 3 introduction, essentially identical with the first embodiment, institute is different
: clutch 2 used is a kind of fluid torque-converter 9, and fluid torque-converter 9 includes pump impeller 10, turbine 11, guide wheel 12, pump impeller
10, turbine 11, guide wheel 12 are mounted in closed shell, and the inside is full of oil liquid, the power output shaft phase of pump impeller 10 and motor 1
Connection, turbine 11 are connected with the input terminal of speed changer 3.
When work, motor 1 drives pump impeller 10 to rotate, and the blade of pump impeller throws to oil by guide wheel in the turbine on opposite, whirlpool
The vane stress of wheel and rotate, pass through speed changer drive driving wheel rotation.The later oil that does work, which backwashes, pushes pump impeller by guide wheel
Rotation.It is this that not only there is very high transmission efficiency by way of liquid transmission compared with positive drive, but also have good
Buffering and fluid drive effect.When motor start-up revolving speed is lower, subsequent load might not be rotated with it, and make electricity
The starting of motivation, which is consumed energy, to be reduced.When encountering obstacle in vehicle transport, the revolving speed of turbine is reduced, but pump impeller still can be normal
Operating, can thus accumulate torsion makes the driving wheel of turbine side slow transit through obstacle, thus the outfit of motor does not need
The case where excessive consideration starts and crosses a ridge, configuration can reduce, and working performance greatly improves.
The third embodiment: Fig. 3 recommends a kind of more optimal structure type: this on the basis of previous embodiment
The power supply of electric truck is the elevated line set up on the transport route, is powered by pantograph 17 to truck.Pantograph 17 is logical
Ignition distributor 18 and wire connected battery 14 are crossed, battery 14 is connected by controller 13 and power supply line with motor 1.Operator
Member drives vehicle by control signal 18 and controller 13.There are lead storage battery 15 and capacitor batteries 16 used herein of battery 14
Two kinds.The output of lead storage battery 15 is stablized persistently, but the charging time is longer.Capacitor batteries 16 can be with quick charge.The two is coordinated mutual
It mends, it is ensured that the steady operation of motor 1.
It is two coaxial series electric motors used herein of motor 1, passes through clutch 2 and speed changer 3 and left and right two respectively
A 4 phase of driving wheel transmission.Speed changer 3 therein is two-stage planet speed changer, has biggish transmission ratio and speed regulation area
Between, it lays particular emphasis on and keeps biggish tractive force, particularly suitable for the low speed load-carrying operation in the poor mining area of road conditions carries out.
In addition, being equipped with brake power generating device 20 on the driving wheel 4, wheel is engaged with engine and is rubbed when the vehicle is braked
It wipes, produces electricl energy and be transmitted back to battery 14, the energy of a part brake can be recycled.
