Comprise that accompanying drawing is for providing the present invention further to be understood, they are included and are constituted the application's a part, and accompanying drawing shows embodiments of the invention, and play the effect of explaining the principle of the invention with this specification sheets.In the accompanying drawing:
Fig. 1 a shows the front view of the middle-size and small-size door machine traveling gear of prior art.
Fig. 1 b shows the interior equalizing bar up and down and the draw bail that connects hinge of middle-size and small-size door machine traveling gear of prior art.
Fig. 2 a shows the front view according to middle-size and small-size door machine traveling gear of the present invention.
Fig. 2 b shows according to equalizing bar up and down and the draw bail that connects hinge in the middle-size and small-size door machine traveling gear of the present invention.
The specific embodiment
Now with embodiments of the present invention will be described by referring to the drawings in detail.Now will be in detail with reference to the preferred embodiments of the present invention, its example is shown in the drawings.In the case of any possible, in institute's drawings attached, will use identical mark to represent same or analogous part.In addition; Although employed term is from public term, to select among the present invention; But some mentioned terms possibly be that the applicant selects by his or her judgement in the specification sheets of the present invention, and its detailed meanings is explained in the relevant portion of the description of this paper.In addition, require not only through employed actual terms, but also will understand the present invention through the meaning that each term contained.
Principal feature of the present invention is to connect equalizing bar and following equalizing bar with vertical connection hinged shaft mechanism.This structure is the design of a kind of brand new, is that design concept or mentality of designing all have greatest differences with in the past prior art.
Fig. 2 a shows the front view according to middle-size and small-size door machine traveling gear of the present invention.Fig. 2 b shows according to equalizing bar up and down and the draw bail that connects hinge in the middle-size and small-size door machine traveling gear of the present invention.
Shown in Fig. 2 a and 2b, middle-size and small-size door machine traveling gear according to the present invention mainly comprises equalizing bar 201, following equalizing bar 202, connects hinge 203 and elastic cushion block 204.In Fig. 2 b, the following contact surface of last equalizing bar 201 and the last contact surface of following equalizing bar 202 are against each other.
Particularly, in the present invention, connect hinge 203 and adopt vertical structure.Shown in Fig. 2 b, this connection hinge 203 is arranged between the last contact surface of following contact surface and following equalizing bar 202 of equalizing bar 201, should go up equalizing bar 201 and this time equalizing bar 202 in order to connect.The long axis direction (promptly the edge connects the direction on the long limit of hinge 203) that it should be noted that connection hinge 203 of the present invention is perpendicular to above-mentioned following contact surface and above-mentioned last contact surface.
In this embodiment, be provided with corresponding opening in the last contact surface of the following contact surface of last equalizing bar 201 and following equalizing bar 202.Connect hinge 203 and run through the opening in the opening in the contact surface on this and this time contact surface.Preferably, the opening of above-mentioned following contact surface and above-mentioned last contact surface lays respectively at the centre of above-mentioned following contact surface and above-mentioned last contact surface.
Simultaneously, an elastic cushion block 204 is configured to around this connection hinge 203.Shown in Fig. 2 b, this elastic cushion block 204 is placed between the last contact surface of following contact surface and following equalizing bar 202 of equalizing bar 201.The material of this elastic cushion block 204 is preferably selected elastomeric material for use.
According to a preferred embodiment of the present invention, elastic cushion block 204 preferably can fill up the space except that connecting hinge 203 between above-mentioned following contact surface and the above-mentioned last contact surface, thereby better buffer action can be provided.
On the other hand, the detachable elastic cushion block of above-mentioned elastic cushion block 204 preferred employings.Bear the outer pressure that carries and conduct oneself with dignity owing to this elastic cushion block 204 needs to replace connection hinge of the prior art,, therefore choose detachable elastic cushion block and can make things convenient for actual replacement to operate greatly so possibly need to change more continually.
In sum, the present invention possesses bigger advantage in the following aspects at least:
(1) transmission of optimization power
The equalizing bar hinge of conventional design also will bear the transmission of this hinge place power (outer carrying+deadweight) except will bearing the contact between the equalizing bar up and down.This just requires hinge that enough intensity will be arranged.So diameter of axle size is just bigger, to the processing request of axle also than higher.The design of vertical hinge of the present invention has at first been avoided the power transmission born by hinge from structure.Connect the task that hinge is undertaken herein,, only bear the corresponding tractive force that this place produces except plaing the contact effect equally.And this tractive force is compared with outer carrying+deadweight, and is much smaller undoubtedly.This just shows: through adopting vertical structure of the present invention, then the hinge size can reduce and the processing request of hinge also can correspondingly reduce.
(2) effect of elastic cushion block
The main effect of caoutchouc elasticity cushion block of the present invention is exactly to be used for transmitting outer carrying+deadweight.Simultaneously, the characteristic by caoutchouc elasticity cushion block itself determines that this cushion block also has the function of buffering and shock-absorbing.This just might solve (being to improve at least), and tired rich designer's equalizing bar hinge place structure in use ftractures always for a long time " long-standing " problem.In addition, this elastic cushion block also guarantees easily cushion to be changed, and has thoroughly abandoned in the past hinge axis hole place framing member and has repaired the disadvantage that adopts electric welding easily.
(3) the rail phenomenon is gnawed in improvement
Door machine large vehicle walking rotation browsing rail is a more scabrous problem in design always.Although the measure of in design, taking to strengthen the tread width is remedied in the past, this method of designing itself has just determined that can't fundamentally avoid gnawing the rail phenomenon produces.Through adopting the traveling gear of vertical hinge device of the present invention, just might avoid gnawing the rail phenomenon fully and take place.Because when wheel generation side force is desired to cause gnawing the rail generation, can make the bogie frame that vertical hinge device is housed produce relative deflection, this will improve the degree of gnawing rail greatly.Simultaneously also gnaw the rail problem a kind of new approaches are provided for solution fundamentally.
In addition, the benefit that adopts vertical hinge device also can be to simplifying the equalizing bar structure fabrication, reducing production costs and row debugs examination etc. and brings many creationary facilities except above-mentioned 3 of speaking of.
Those skilled in the art can be obvious, can carry out various modifications and modification and without departing from the spirit and scope of the present invention to above-mentioned exemplary embodiment of the present invention.Therefore, be intended to that the present invention is covered and drop in appended claims and the come scope thereof to modification of the present invention and modification.
