Description

A kind of 100% low-floor tramcar power steering truck frame work

Technical field

The utility model is related to tramcar field, particularly a kind of 100% low-floor tramcar electronic-controlled power steering framework Frame.

Background technology

With the continuous progress of science and technology, the continuous improvement of people's living standard, comfort level of the people to trip There is requirement higher.Reality is that the vehicle of traveling is more and more, and urban road is repaiied closeer and closeer, and road surface is opened up wider and wider, so And congestion in road phenomenon is still serious, the travel time of city dweller is continuously increased, and city faces increasingly severe Waste gas, noise etc. pollute.

The problems such as in order to alleviate urban traffic blocking and pollution, many cities are all to accelerate subway construction as alleviation city The major way of traffic congestion, but subway system has that cost of investment is big, the construction period.And the low-floor modern times have Rail electric car it is a kind of between bus and subway in low capacity the vehicles, with guiding urban development and alleviation The effect of urban traffic blocking, supplement, extension, contact and transition and small and medium-sized cities master at the same time as large conveying quantity track traffic 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 only that the main structure of 100% current low-floor tramcar power truck is substantially two curb girders and two crossbeams Vertical widget, is then linked together them by weld seam；Motor cabinet and speed reducer base are generally casting or board It is welded, casting monnolithic case seems that comparing is heavy, and welding capacity is just than larger if board welding.Due to bogie It is a more complicated part of stress, is easier to cause stress concentration if weld seam is excessive, so as to cause the failure of framework.

Specific embodiment

A kind of 100% low-floor tramcar power steering truck frame work, as shown in figure 1, including：Drawing pull bar seat 1, curb girder 2nd, crossbeam 3, gear block 4, motor cabinet 5, brake clip clamp block 6, primary spring seat 7, secondary spring seat 8, magnetic rail brake device are oriented to Seat 9, axlebox rod seat 10, transverse direction and vertical damper holder 11, horizontal stopping seat 12 etc., wherein：

The overall architecture of this power truck is H-shaped, and base plate is one piece of whole plate (shape and structure are as shown in Figure 4), curb girder 2 It is fixed on base plate by the way of welding with crossbeam 3, crossbeam is integrated by connecting method and side beam welding.

Curb girder 2 is the box beam of upper and lower cover plates and left and right web group weldering, and curb girder middle part is in concave, and two curb girders are recessed Shape middle part is connected by crossbeam 3, and recess is provided with secondary spring seat 8 under the every middle part of curb girder；Gear block 4 and motor cabinet 5 by Pipe and board are welded, and are in order to reduce the quantity of weld seam, so as to reduce stress collection using circular tube structure main purpose Middle region；As shown in Figures 2 and 3, motor cabinet 5 and gear block 4 are welded in side rail outer；Brake clip clamp block 6 respectively with gear Block 4 and motor cabinet 5 are integrally welded；Magnetic rail brake device guide holder 9 is additionally provided with side rail outer web；Set on curb girder lower cover There is primary spring seat 7；Curb girder two ends are provided with transverse direction and vertical damper holder 11；Curb girder lower end is provided with 4 groups of axlebox rod seats 10；Two Side rail inner web is provided with 4 horizontal stopping seats 12；Wherein, each part is existed with side beam welding by the way of welding Together.

Crossbeam is the box girder construction that U-shaped bending plate (shape and structure are as shown in Figure 5) and lower cover group are welded.Traction Draw-bar seat 1 is welded on cross rail outer.

This power steering truck frame work has with the difference of existing similar dynamic bogie frame：

1. the motor and speed reducer seat of this framework is the welding structure of section bar (pipe) and sheet material, as shown in Figure 2 and Figure 3；Type Material effectively reduces the quantity of weld seam, so as to reduce region of stress concentration；And the motor and speed reducer bearing of similar framework Then for sheet material is welded or be casting, welding capacity is more long than the larger or cycle.

2. the curb girder of this framework is welded for sheet material, and simple structure is with short production cycle；And the curb girder of similar framework is plate Material and casting are welded, and complex structure, the production cycle is long.

3. the base plate of the crossbeam of this framework and curb girder is an entire plate, as shown in figure 4, reducing crossbeam and curb girder combination weldering The welding capacity for connecing, Reducing distortion amount and region of stress concentration；And similar framework is then for crossbeam and curb girder have the base plate of oneself, from Welded together again after into box-structure, welding capacity is big, and deformation and stress ratio are larger.

4. the crossbeam of this framework is welded as box girder construction using U-shaped bending plate and base plate, as shown in figure 5, effectively subtracting The welding capacity of crossbeam is lacked, so that less region of stress concentration；And the crossbeam of similar framework is then for four blocks of sheet materials are welded, Welding capacity deforms and stress ratio is larger than larger.

5. drawing pull bar seat 1, the axlebox rod seat 10, transverse direction and vertical damper holder 11 of this framework is forging, and phase Like framework drawing pull bar seat and axlebox rod seat be casting, laterally and vertical damper holder be sheet material weldment, it is clear that forging Performance it is more excellent.

6. the quality of this framework is about 835kg, than the light weight of similar framework.
