Description

Interchangeable tramcar bogie frame is welded entirely
Technical field
A kind of bogie is the utility model is related to, more particularly to one kind welds interchangeable tramcar bogie frame entirely.
Background technology
The homotype bogie frame used on existing rail cars uses cast welding integral structure, main stressed member, such as Curb girder etc. uses monoblock cast structure, and development cost is high, cycle length, and craftsmanship is relatively poor, while weight control in design process Relative difficulty processed.
Utility model content
The utility model aims to solve the problem that drawbacks described above, there is provided one kind welds interchangeable tramcar bogie frame entirely.
In order to overcome defect present in background technology, the utility model solves technical solution used by its technical problem It is:This to weld interchangeable tramcar bogie frame entirely and include framework main body, framework main body is mainly by the sunk type of both sides Curb girder and the connection crossbeam at middle part composition, a diagonally opposing corner of framework main body are bolted motor gearbox mounting base, are somebody's turn to do Mounting seat of brake, another diagonally opposing corner welding compound installation of braking motor of framework main body is also bolted in diagonally opposing corner Seat.
Another embodiment according to the present utility model, further comprises the sunk type curb girder bag of the framework main body both sides Mounting base substrate is included, bolt mounting holes and card slot stop configurations are provided with mounting base substrate, are welded to connect on mounting base substrate Upper cover plate one, upper cover plate two and lower cover, the side of mounting base substrate are equipped with magnetic rail braking stopping seat.
Another embodiment according to the present utility model, further comprises the motor gearbox mounting base, brake peace Dress seat is connected by bolts on mounting base substrate.
Another embodiment according to the present utility model, further comprises that a diagonally opposing corner of the framework main body passes through spiral shell Tether and connect mounting seat of brake.
The beneficial effects of the utility model are:It is this to weld interchangeable tramcar bogie frame entirely and employ full welding Interchangeable structure, power and non-powered bogie frame can be freely formed for different bogie functional requirements, exchange flexibly, Simple and reliable for structure, applicability protrudes, while the bogie frame uses all-welded structure, has taken into account rigidity, intensity and light weight The requirement of change.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the utility model;
Fig. 2 is the structure diagram of the part of framework main body;
Wherein:1st, framework main body, 2, braking motor composite mounting base, 3, motor gearbox mounting base, 4, brake installation Seat, 5, mounting base substrate, 6, magnetic rail braking stopping seat, 7, upper cover plate one, 8, upper cover plate two, 9, lower cover.
Embodiment
As shown in Figure 1, this framework main body 1 for welding interchangeable tramcar bogie frame entirely is tied using full welding Structure, is mainly made of the sunk type curb girder of both sides and the connection crossbeam at middle part.
The primary load bearing structure of the framework main body 1 is welding box beam structure, taken into account rigidity, intensity and it is light-weighted will Ask, while large-sized structural parts are substantially shorter the construction cycle using all-welded structure relative to monoblock cast, save development cost, And largely avoid the quality problems in manufacturing process, such as casting flaw.The framework main body 1 it is compact-sized, it is necessary to Arrange a large amount of parts, use multi-functional mounting base to achieve the purpose that to assemble and efficiently use space.
The bogie uses interchangeable structure to meet the different functional requirement of bogie.One of framework main body 1 is tiltedly right Motor gearbox mounting base 3 is bolted in angle, mounting seat of brake 4 is also bolted in the diagonally opposing corner, framework main body 1 Another diagonally opposing corner welding braking motor composite mounting base 2.
For power truck:The motor gearbox mounting base 3 that framework main body 1 is arranged with diagonally opposing corner is bolted, Form complete motor gearbox suspension;For non-powered bogie:Framework main body 1 and the brake of diagonally opposing corner arrangement are pacified Dress seat 4 is bolted, and forms complete foundation brake suspension.The interchangeable structure structure major advantage has:Only need A kind of framework main body 1 is designed, the design cycle is short and has been greatly saved follow-up test verification and process exploitation cost;Motor gearbox Mounting base 3 or mounting seat of brake 4 are only installed interface with framework main body 1 and are consistent, its mounting base itself is relatively independent, can root Exploitation is flexibly designed according to different functional requirements;Motor gearbox mounting base 3 or mounting seat of brake 4 and framework main body 1 It is connected by high-strength bolts, is bolted assembling simply and connection is safe and reliable.
Braking motor composite mounting base 2 is provided with the framework main body 1 of the bogie, which is multi-functional installation Seat, has the function of hanging brake and motor concurrently, and mounting base uses all-welded structure, is laid out advantages of simple, and craftsmanship is good, with Framework main body 1 is weld connection, and carrying out interchangeability for framework main body 1 provides advantage.
As shown in Fig. 2, the sunk type curb girder of 1 both sides of framework main body includes mounting base substrate 5, set on mounting base substrate 5 There are bolt mounting holes and card slot stop configurations, upper cover plate 1, upper cover plate 28 and lower cover 9 be welded to connect on mounting base substrate 5, The side of mounting base substrate 5 is equipped with magnetic rail braking stopping seat 6.The framework main body 1 of the bogie and motor gearbox mounting base 3 or Mounting seat of brake 4 is connected by bolts on mounting base substrate 5, sets bolt mounting holes and card slot to stop on mounting base substrate 5 Structure is kept off, the connection structure is simple, is easily assembled to, and bolt strained reasonable, connection is reliable.Mounting base substrate 5 only with upper cover plate one 7th, by being welded to connect, remainder is hanging for upper cover plate 28 and lower cover 9, while substrate connection intensity is ensured, reserves Bolt installation space, ensures bonding strength.
