Specific embodiment
The invention is further explained in the following combination with the attached drawings of the specification.
As shown in figure 3, a kind of six wheel drive dumpers, including vehicle frame, walk on stage 31, container 32, power assembly, Electric Motor Wheel
Group, the electric drive system and cooling system for driving electric wheel set.
As shown in figure 4, it is described walk on stage 31 top center position be equipped with driver's cabin 34, the top position walked on stage is in driver's cabin
34 rear be equipped with current transformer 36, walk on stage 31 top in the left side of current transformer 36 be equipped with Electric Appliance Cabinet 35, walk on stage 31 top in
The right side of current transformer 36 is equipped with resistance box 37；The top walked on stage is equipped with air filter 33 in the front of driver's cabin 24.Walk equipments on stage
Arrangement keeps being symmetrically arranged, and the weight that left and right is born is consistent substantially, and driver's cabin, current transformer position are in walking on stage
Between, steel construction of walking on stage bears weight and concentrates on walking on stage on center line.
As shown in Fig. 2, electric wheel set is divided into three groups, it is front-wheel, middle wheel and rear-wheel respectively, vehicle uses three different drives
Movement controller controls front-wheel, middle wheel, rear-wheel.Front-wheel is connect by independent formula suspension of lighting up with vehicle frame, and steering is equipped with before two front wheels
Cylinder and steering linkage realize front-wheel steer function；Need to design connecting component between the piston rod and motor of front suspension cylinder, it will
Forward mounting is effectively connect with preceding wheel assembly；Mounting base is cooperated using bellmouth and the piston rod of forward mounting, the bottom of bellmouth
Portion is connect using bolt with piston rod, and the bottom of mounting base is embedded in the groove on motor housing in the form of boss, and passes through
Guarantee the laterally cooperation with longitudinal face on boss, to provide the transfer surface of lateral force and longitudinal force；In vertical direction, boss
It can cooperate with the groove surface on motor casing after intermediate bottom surface processing, to provide the support of vertical force；Finally, mounting base passes through week
8 bolts enclosed are linked together with motor housing；The maximum feature of candle formula suspension is that pneumatic cylinder provides pivot stud, is turned to
When wheel rotated around suspension cylinder, meanwhile, pneumatic cylinder by the mounting base of side and vehicle frame by being bolted together, self-unloading
In the process of moving, wheel moves up and down vehicle along the main pin axis being fixed on vehicle frame；The underpart of the piston rod of front suspension cylinder uses
The tapered surface and forward mounting mounting base that length is 225mm cooperate, meanwhile, in order to improve the straight motion stability of vehicle, stub
5 degree of introversion；Forward mounting uses the advantages of candle formula suspension: when suspension deformation, castor will not change,
It is only that wheelspan, wheelbase vary slightly, therefore the handling maneuver for being particularly conducive to dumper is stable and driving stability.Middle wheel, rear-wheel
Suspension use identical form to improve versatility and interchangeability；The rear suspension system includes two suspension cylinder seats, sets
The pneumatic cylinder in suspension cylinder seat is set, the upper arm-tie hung at the top of cylinder seat is set and is arranged in and is hung under cylinder seat bottom
Pull rod；In order to efficiently and securely connect wheel set and vehicle frame, devises upper arm-tie and the two is attached with lower pull rod, together
When, according to the specific shape of motor housing, specific suspension mounting bracket assembly is devised on motor housing, to upper arm-tie, under
Pull rod and pneumatic cylinder provide reliable mounting base；The up and down motion of wheel is constrained by upper arm-tie and lower pull rod.Oil
It being arranged symmetrically before and after gas suspension cylinder, upper and lower ends are attached with vehicle frame and suspension mounting base respectively using oscillating bearing, equally,
Lower pull rod also uses oscillating bearing to be attached with vehicle frame and suspension mounting base with upper arm-tie；Due to the suspension of middle wheel and rear-wheel
System structure is identical, and in order to describe conveniently, the suspension of middle wheel and rear-wheel is collectively termed as rear suspension system below.After hang
Using independent suspension, increase oleo-pneumatic suspension, by adjusting the parameter of oleo-pneumatic suspension, can effectively improve the smooth of dumper
Property.
As shown in Fig. 2, diesel engine, main generator, transfer case, water pump, hydraulic pump are using mechanical connection in electric drive system
Axis is uniformly lifted on vehicle after being completed under vehicle, and power assembly center line is overlapped with vehicle frame longitudinal centre line；It is set on vehicle frame
Standby arrangement keeps being symmetrically arranged, and the weight that vehicle frame or so is born is consistent substantially.The same Diesel Engine Mechanical of alternating current generator
Connection generates three-phase alternating current when the rotation of Diesel Driven synchronous generator, supplies traction convertor, and traction convertor passes through
By the mutually independent VVVF inverter in six tunnels after rectifier rectification, the uncontrollable three-phase alternating current of main generator input is become
It changes the three-phase alternating current controllable for voltage, frequency into, respectively drives six traction electric machines, six traction electric machines pass through six decelerations
Device passes torque to six independent tires, and driving vehicle advances；Wherein traction electric machine is AC induction motor.
As shown in figure 5, the cooling system includes fan, radiator, diesel engine expansion tank, air-air intercooler, traction
Motor and current transformer radiator, point expansion tank, water pump, water segregator and cooling line.High-temperature water for cooling down diesel engine is logical
Become cold water after crossing radiator, then backs within diesel engine and form diesel engine cooling circuit；The air-flow that fan is formed can be with
It radiates to radiator.Radiator is connect by gas removing pipe with diesel engine expansion tank, and diesel engine passes through diesel engine gas removing pipe
It is connect with diesel engine expansion tank, diesel engine expansion tank passes through the circuit moisturizing of water supply pipe elder generation diesel engine cooling.Diesel engine passes through
High temperature compressed air is transported in air-air intercooler and cools down by high-pressure air pipe, is cooled into low-temp low-pressure air and returns again
It returns in diesel engine；The air-flow that fan is formed can radiate to air-air intercooler.Water pump will pass through traction electric machine and unsteady flow
Device radiator water at low temperature after cooling is sent in six traction electric machines and current transformer by the lower water chamber of water segregator, will be with traction electricity
High-temperature water after machine and the cold progress heat exchange of current transformer is sent to traction electric machine and current transformer radiator by the upper water chamber of water segregator
Middle cooling forms cooling circuit.Cooling system of the present invention is compared with air-cooled, and the small volume that water-cooled cooling system occupies is cold
High-efficient；Using water-cooling system, the better tightness of component can be effectively prevented dust in air and fall into current transformer and traction
In motor.
