Description
Technical field
The present invention relates to electric automobiles, and in particular to a kind of trailing wheel four-wheel driven electric vehicle.
Background technology
It to storage battery is power that electronic car of hauling goods, which is, motor for driving the means of transport hauled goods；Electric power is as a kind of
Environmental protection, cleaning, the high important energy of conversion ratio, the update of the vehicles is driven using electric power as application, promotes traffic
The low-carbonization development of carrier, reduces transportation cost, saves the energy, environmental protection, is the important topic that countries in the world are studied
One of, by the development of decades, have been applied in urban public traffic vehicles, factories and miness electric transportation vehicle, electric urban environmental sanitation is clear
The numerous areas such as clean vehicle, engineering, tunnel, subway work special-purpose vehicle.Electronic car of hauling goods is with its strong applicability, maneuverability,
Safeguard it is simple, it is easy to maintenance, it is cheap the advantages that, can neatly navigate between narrow and small road.Electronic car of hauling goods, extensively
The short-distance transport field such as keep a public place clean applied to family, town and country, individual taxi, plant area, mining area, environmental sanitation, community.It is mainly used in electronic
Lifting fortune water base car etc.；Brick field, Yao Chang, fire resisting factory, ceramics factory, the electronic kiln loading vehicle for being calcined factory etc., electronic discharging car etc.；Work
Journey, tunnel, the electric transporting vehicle of environmental sanitation, electric self-unloading car, electric sanitation clearing and transporting vehicle etc..Electric transporting vehicle and electric self-unloading car
It is also applied to flour mill, ore dressing plant, chemical plant, furnace charge factory, plant etc..Electronic car of hauling goods, use environment is typically relatively more severe,
It is required that motor, storage battery is relatively durable, adapts to the environment such as dust, high temperature, crankcase ventilaton, to vehicle frame material, welding process requirement
It is stronger to vehicle climbing capacity in itself and cushioning ability demand Deng higher, adapt to the requirement of plant operation environment.
Current market sales of electronic car of hauling goods can be divided into that three-wheel hauls goods car and four-wheel is hauled goods car by wheel quantum count, all
It is to drive vehicle body using two trailing wheels, damper uses vertically disposed spring damper, and this electronic car owner that hauls goods will deposit
In following defect：First, damping performance is bad, it is impossible to filters out body sway caused by bump, holds when hauling goods
Easily cause goods to rock, spill, damage, waste goods, pollute ground；Secondly, climbing capacity is weak, and electronic car of hauling goods is using
During be frequently necessary to be climbed in the case where vehicle body is in full load condition, it is existing in face of the bigger situation of gradient angle
Electronic car being short of power due to itself of hauling goods, it is impossible to slope is climbed up by the driving force of oneself, it is necessary to by Manual-pushing or its
The power of his equipment is pulled, and very big inconvenience is caused during use；Again, stability is bad, and existing three-wheel is drawn
Lorry is moved after the center of gravity of vehicle fully loaded with cargo when, can make vehicle body hypsokinesis, causes personnel to injure or the damage of goods vehicle；
Finally, bearing capacity is weak, and rear portion only relies on two wheels and axle support vehicle body, and the goods weight that can be loaded is small, and overload goods
Damage that thing easily makes wheel or axletree deforms, adds the maintenance of later stage vehicle, and reduce the service life of vehicle.
Therefore, it is good to produce a kind of damping performance, climbing capacity is strong, and stability is good, and the strong trailing wheel 4 wheel driven of bearing capacity is electronic
