Dry mode of transportation, the affirmative of citizen and government is subject to its convenience, comfortableness, aesthetic property and the feature of environmental protection.
1. raceway surface is flushed with highway pavement, therefore will not constitute obstacle to other vehicles；
2. low-carbon environment-friendly, to city substantially without exhaust emission, noise is low, and energy consumption is only the 1/10 to 1/5 of bus, is used
Long lifespan, recoverable rate is high；
3. curve negotiation ability and climbing capacity are strong, and track can be in urban district road surfacing, and compared with subway, construction investment is few
(accounting for 1/5), construction speed is fast, though cost is higher than fast public traffic system, freight volume is big and service level can reach subway or
Light rail standard；
4. injection volume and good operational stability, passenger's ride quality is high, safe；
5. low-floor design, facilitates mobile in passenger car and quickly gets on or off the bus, to the elderly, disabled person, children and heavy burden
People's boarding bring great convenience；
70% low-floor tramcar is compared, without step, passenger passes through square 100% low-floor tramcar in-car in the car
Just, it is the main flow direction of current tramcar development, will possesses wide market prospects.
It is all independent that the main structure of 100% current low-floor tramcar bogie is substantially two curb girders and two crossbeams
Widget, they are linked together by weld seam then；Brake clip clamp block and its attachment weld between framework are equal
Compare many；Because bogie is a more complicated part of stress, it is easier to cause stress concentration if weld seam is excessive, from
And cause the failure of framework.
The 100% low-floor tramcar non-powered bogie frame puts forward under the background condition.

Compared with prior art, the utility model has the advantages that：With compact conformation, good appearance, dependable performance it is excellent
Point, disclosure satisfy that 100% low-floor tramcar single stage suspension device, secondary suspension device, drawing pull bar, vertical and horizontal stop
The mounting interface requirement of gear, vertical and lateral damper, brakes etc..This framework is structurally characterized in that with the central point of framework
It is arranged symmetrically, can be used with 180 ° of tunings.
Brief description of the drawings
The utility model will be illustrated by example and with reference to the appended drawing, wherein：
Fig. 1 is the structural representation of this bogie；
Fig. 2 is the structural representation of brake clip clamp block 5；
Fig. 3 is the structural representation of the unsplit bed(-)plate of non-dynamic framework；
Fig. 4 is the structural representation of the U-shaped bending crossbeam of non-dynamic framework.
Specific embodiment
A kind of 100% low-floor tramcar non-powered bogie frame, as shown in figure 1, including：Drawing pull bar mounting seat
1st, curb girder 2, crossbeam 3, secondary spring seat 4, brake clip clamp block 5, single stage suspension device mounting seat 6, magnetic rail brake device guide holder 7,
