Abstract
The invention relates to a railway vehicle flexible bogie, wherein the middle of a left side frame and a right side frame are fixedly connected in an integral mode through a flexible crossbeam formed by four steel plates; gaps are reserved between the four steel plates; the left side frame and the right side frame are respectively provided with an elastic bumper block in a mounted mode; and a rubber pad which is used as single stage suspension is arranged between each elastic bumper block and a shaft housing. According to the railway vehicle flexible bogie, flexibility of a framework is achieved, the left side frame and the right side frame can easily nod relatively so that the framework can be adapted to a triangle pit with big railways; thus flexibility of the framework is achieved, the single stage suspension is a thin layer of rubber pad, production cost is reduced, and the railway vehicle flexible bogie is well adapted to unsmooth lines.
Description
Technical field
The present invention relates to a kind of guideway vehicle compliance steer frame, belong to the rail vehicle truck technical field.
Background technology
It is the distortion irregularity that vertical flexible suspension overcomes circuit that traditional bogie truck generally adopts H type framework, rigid beam, dependence one, rigid frame at wheel when driving to transition curve, because the superelevation of curve track, bear than the high pulling torque effect part, and the speed of a motor vehicle is when higher, and framework and is that the junction between the vertical flexible suspension also can be subject to greater impact power; In the structure design of conventional bogie, motor is installed on the framework, for allow motor and wheel to dynamic disturbances and transmission moment the mechanisms such as complicated shaft coupling and gear case need to be set, this bogie structure is complicated, production efficiency is low, and the wheel of this bogie truck is to wheelbase is large, weight is large, make bogie truck little curving performance, energy saving, the performance figure such as compliance of circuit irregularity are difficult to remarkable lifting.
Find through retrieval, Chinese invention patent CN101565049 B, it discloses a kind of steering frame of hinged frame linear electric motor, and two T-shaped frameworks are hinged by rubber nodal point and center crossbeam respectively; The center crossbeam sidepiece links to each other with the traction crossbeam on top by longitudinal tie, the traction crossbeam connects respectively the first curb girder, the second curb girder by oil-pressure damper, center crossbeam links to each other with linear electric motors by drawing pull bar, the draw that this design can improve bogie truck transmitting tractive power and improve linear electric motors.
When wheel when driving to transition curve, two hinge-points can bear larger moment of torsion and twist in right amount, thereby framework is played a protective role.The visual contrast file is realized the flexibility of bogie truck by the rubber nodal point of hinged place, the different rubber nodal point of bogie truck needs design according to different automobile types, this structure uses rubber nodal point to realize reversing, the parameter discrete properties of rubber nodal point is larger, along with variation of ambient temperature, the performance perameter of rubber nodal point often differs larger with design value, simultaneously the easy season cracking of rubber, reliability is relatively poor, and service life is relatively short.And motor still is installed on the bogie truck, takes turns greatly to wheelbase, fails to significantly improve the bogie truck properties.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the above-mentioned deficiency of prior art, and a kind of guideway vehicle compliance steer frame is provided.
In order to solve above technical matters, guideway vehicle compliance steer frame provided by the invention, composition comprises: truck frame, lay respectively at two magneto-electric machines of truck frame front side and rear side, be arranged at the air bellow of truck frame top, be arranged at the front and back wheel pair of truck frame below, described truck frame has left frame, left side frame, it is characterized in that: the middle part of described left and right side frame is connected to one by the flexible crossbeam that is comprised of four steel plates, leave the gap between described four steel plates, described left frame, it is bumper block that left side frame is separately installed with one, and described one is the rubber pad that is provided with between bumper block and the axle box as single stage suspension.
The present invention further improves and is:
(1), from the end face of flexible crossbeam, described four steel plates distribute radially, and its in a lateral direction, symmetrical on the vertical direction.
(2), described rubber pad is the individual layer rubber pad, thickness range is 30～100mm.
(3), described air bellow top across be provided with one and be used for the rebound of captiveing joint with car body.
(4), guideway vehicle compliance steer frame of the present invention also has the stop gear for restriction rebound transverse shifting amplitude, described stop gear comprises the horizontal stop seat at the left and right bogie side frame of being fixed on of the symmetrical elastic buffer rubber backstop mount pad that is fixed on the rebound lower surface, symmetry middle part, on the described elastic buffer rubber backstop mount pad elastic buffer rubber backstop is installed, when rebound moves laterally to end position, the elastic buffer rubber backstop of rebound offset direction one side is withstood the horizontal stop seat of respective side, and it is spacing that rebound is obtained.
(5), also to have the L-type anti-side rolling torsion rod, two that two ends connect respectively bogie side frame and rebound be that vertical damper, two is lateral damper to guideway vehicle compliance steer frame of the present invention.
Among the present invention, the flexible crossbeam that connects left and right side frame is comprised of four steel plates, and it has certain flexibility, makes the left and right side frame motion of relatively nodding easily, to adapt to the larger twist of track of track; For the bogie truck of disparity items, can adjust according to designing requirement size, the angle of these four steel plates, and the steel of selecting different performance, the flexibility of truck frame is changed, to adapt to disparity items; Because framework has been realized flexibility, thereby makes single stage suspension of the present invention be reduced to very thin one deck rubber pad, has reduced productive costs, simultaneously to the good compliance of having of circuit irregularity.
