At present; Energy-saving and emission-reduction become the countries in the world Focal Point of Common Attention, and tramway train is being favored, and are about to a large amount of place in operations; This not only meets the development topic of country's " science and technology, humane, ecological, efficient ", and has represented the development tendency of Modern Traffic.Tramway train is modal to be exactly the lowland wooden handcart.Restriction because of arranged by driving system and electrical equipment divides 50%～70% low floor, 100% low floor again.Often definite with the ratio of the area of the area of low floor part and passenger zone.And 50～70% these ratios commonly; If equal 1.0, then be called 100% low floor.Non-lowland wooden handcart need be provided with platform usually or on vehicle, install the pedal ladder, to make things convenient for passenger getting on/off.At present; Four common monomer tramway trains; Mostly adopt by two bogie units through axle bonded assembly underframe, be assembled in the structure of the vehicle body that has glass port and floor on the underframe, the length of vehicle body that has glass port and floor is generally about 10-16 rice.The axletree of two band wheels all is installed on each bogie truck, and actuating device makes the power of vehicle ' be directly delivered on the wheel through axletree.The floor of existing vehicle body is installed on the electric car underframe, is made up of a big plane.Because the floor is installed on two bogie units, so height of floor from rail top is higher than wheel, cause floor in the vehicle body face that leaves the right or normal track higher, height to the top of rail reaches more than 0.8～1.1 meter usually.In the highway section of not establishing platform, the pedal ladder that has what step on passenger's needs could arrive in the vehicle body, and passenger (especially physical disabilities) gets on and off very inconvenient.For this reason, just higher platform need be set, this platform mixes the walking along the street section at arteries of communication the current meeting of other vehicles is caused certain obstacle, has also increased the laid down cost of street railway.

In China, existing hinged 6 above light rail electrical cars are adopting 50%～70% low floor technology, but four tramway trains still adopt high floor form so far.Therefore, four tramway trains developing a kind of 70% low floor are that the new problem that solves is badly in need of in the home and abroad always.

The utility model content:

The purpose of the utility model provides a kind of four tramway trains of local low floor; Solved height of floor from rail top that existing electric car vehicle body exists and be higher than bogie truck and cause passenger's inconvenient defective that gets on and off, the reasonable in design of its underframe need not to be provided with low platform or installing pedal ladder on vehicle; The passenger directly gets on and off; Move rapid, safety, not only help the current of other vehicle, and the laid down cost of having saved street railway.

The technical scheme that the utility model adopted is: four tramway trains of this part low floor comprise by two bogie units through axle bonded assembly underframe; Be assembled in the vehicle body that has glass port and floor on the underframe; Its technical essential is: the floor in the said vehicle body is divided into forward and backward operator's compartment district and middle passenger zone three parts; The floor in forward and backward operator's compartment district is separately positioned on two bogie units through on the axle bonded assembly high-order underframe; The passenger zone floor is local low floor; Be arranged on along on the middle low order underframe of the inward flange underlying in two operator's compartment districts, the both ends of the local low floor on the middle low order underframe through mark time step respectively with the high-order underframe on the floor in forward and backward operator's compartment district be connected.

Advantage and the good effect that the utlity model has are: because the floor in the utility model vehicle body is divided into forward and backward operator's compartment district and middle passenger zone three parts; And be separately positioned on the step underframe; Two bogie units being arranged on the high-order underframe of forward and backward operator's compartment district below of extremities of body, is that its floor height to the top of rail meets the requirement of local low floor along the zone of the middle low order underframe of the inward flange underlying in two operator's compartment districts just between two bogie trucks; The ratio of the area of low floor part and the area of passenger zone has reached 70～90%; So the reasonable in design of its underframe need not to be provided with low platform or on vehicle, installs the pedal ladder, the passenger directly gets on and off; Move rapid, safety, the laid down cost of having saved street railway.Especially can satisfy the demand that the disabled person gets on and off at an easy rate, mix the walking along the street section, also help other autos only at arteries of communication.Therefore, having solved height of floor from rail top that existing electric car vehicle body exists is higher than bogie truck and causes passenger's inconvenient defective that gets on and off.
