Definitions
- the invention generally pertains to the railway field, and more particularly to the devices used to change the gauge of a railway axis.
- the object of the present invention is a new connection between the wheels and the axle to transmit the torque in a variable gauge railway axle
- Variable gauge rail axles are designed to accommodate many different track gauges. To do this, these axles have a mechanism designed to allow the wheels to slide along the axle between two or more positions corresponding to respective track widths. Once located in the position corresponding to the desired width, a fixing system locks the position of the wheels. Therefore, unlike conventional railway axles, in a variable gauge railway axle the wheels are not locked to the axles.
- variable gauge railway axles Since the wheels are not fixed to the axles, the linkage mechanisms of variable gauge railway axles must have a linkage system capable of transmitting the torque from the wheels to the axle. Indeed, due to the loads that the railway axle supports, as well as the braking efforts to which it is subjected during its normal life, a torque appears that tends to misalign the wheels and the axle. Conventional joint systems that do not allow the possibility of pitching between axles and wheels, such as splined or tongue-and-groove joints, deteriorate rapidly due to the accumulation of fatigue loads. In this context, note that one fatigue cycle occurs for each revolution of the wheel.
- Patent ES2428239B1 of the inventor of the present application, describes a railway axis adaptable to various track widths.
- the torque transmission problem is solved by means of a joint system formed by two semi-compasses respectively fixed to the axle and to the wheel and articulated in such a way that they can be opened or closed to adapt to the different positions of the wheel, as well as pitch to absorb the misalignments between wheel and axle, transmitting the torque without play in all positions of the wheel with respect to the axle.
- Figs. 1a and 1b show sectional views of a connection (100) according to patent ES2428239B1.
- the articulated compasses are made up of two semi-compasses (103a, 103b) that have two arms at one end and a single arm at the other, being connected on the side provided with a single arm by means of ball joints (104a, 104b). ) and joined by a shaft (106).
- the semi-compass (103a) houses the shaft (106) that stacks the cups (105a, 105b), the ball joints (104a, 104b) and the semi-compass (103b).
- the semi-compass 103a is fixed to the wheel axis (not shown) and the semi-compass 103b to the wheel (not shown). If we are transmitting torque from the semi-compass (103a) to the semi-compass (103b), the semi-compass (103a) transmits the force to the shaft (106), which transmits the torque to the cup (105a) by contact, which also transmits it to the ball joint (104a) and semi-compass (103b), which finally transmits it to the wheel. This is the optimal route for the transmission of torque, since it is always transmitted by pressure between the surfaces in contact.
- the semi-compass (103a) transmits the force to the shaft (106) through the thread, and This is transmitted by traction to the farthest ball joint cup, which transmits the effort by pressure between surfaces to the cup (105b) and from the ball joint (104b) to the semi-compass (103b).
- the route followed involves making the shaft (106) that joins the semi-compasses (103a, 103b) work under traction and also, due to friction between the ball joint and cup, under bending, accumulating a cycle of effort.
- the axis that joins the semi-compasses is the weakest part of the system, the accumulation of fatigue loads could They tend to cause a breakage of the axle and it is a problem for systems that require a greater transmission of forces, such as in the case of tractor axles or with disc brakes incorporated in the central area of the axle.
- the present invention describes an articulated connection for the union between axle and wheel in a variable gauge railway axle that solves the previous problems.
- the main concept consists in the use of a ball joint that connects two forks which, in turn, are respectively connected to the wheel and the axle. This ball joint allows misalignment between the two forks and therefore also between the wheel and the rail axle.
- connection of the present invention basically comprises the following elements: a) First fork
- a fork comprising an inner side and an outer side.
- the end of the outer side is connected to one of the wheel and the railway axle rotatably about an axis transverse to said wheel or axle.
- the connection between the end of the outer side of the first fork to the wheel or axle comprises a bolt oriented along the transverse axis that passes through holes arranged at the ends of two branches of said peripheral side .
- the second fork has an inner side and an outer side.
- connection between the end of the outer side of the second fork to the wheel or axle preferably comprises a bolt oriented along the transverse axis that passes through holes arranged at the ends of two branches on said side. peripheral.
- the ball joint connects the ends of the inner sides of the first and second forks to each other. In this way, an additional degree of freedom is provided to the joint between both forks that allows misalignments between the wheel and the rail axle, thus reducing the wear that occurs during the useful life of said rail axle.
- the ball and socket joint can be implemented in different ways as long as it allows for such misalignments.
- the ball-and-socket joint comprises a central arm on the inner side of the first fork arranged between two lateral arms on the inner side of the second fork.
- opposite faces of the end of the central arm of the first fork comprise two spherical ball joints embraced by two cups fixed by means of two corresponding threaded supports to holes arranged at the ends of the two lateral arms of the second fork.
- the ball joints attached to the faces of the end of the central arm of the first fork are housed inside spherical cavities in the cups which, in turn, are fixed to the side arms of the second fork. In this way, a misalignment can occur between the axes of rotation respectively of the first and second forks, and therefore also between the axes of the wheel and the railway axis.
- each support comprises a first section for support against the cup, a second threaded section for fixing it to the hole at the end of the arm of the second fork, a third threaded section for receiving a fixing, and a fourth section of polygonal shape to adjust the cup in its position.
- These brackets allow easy mounting and dismounting of the ball joint.
- Figs. 1a and 1b show a sectional view of a connection according to the prior art.
- Fig. 2 shows a perspective view of a railway axle with the wheels coupled and provided with a connection according to the present invention.
- Fig. 3 shows a perspective view of a connection according to the present invention.
- Figs. 4a and 4b show perspective views of a connection according to the present invention in a partially disassembled state.
- Fig. 5 shows a perspective view of a connection according to the present invention where the misalignment between both forks can be seen.
- Fig. 6 shows a perspective view showing the coupling between the connection of the invention and the wheel of the railway axle.
- connection (1) An example of connection (1) according to the present invention is described below with reference to the attached figures, in which the different component parts.
- connection (1) is essentially formed by a first fork (2) and a second fork (3) that are connected by a ball joint.
- the first fork (2) has an inner side (21) and an outer side (22). On the outer side (22) it has two essentially parallel branches (221) equipped with two aligned holes for its rotational coupling to the railway axis (100). As can be clearly seen in Fig. 6, the coupling is carried out by passing a bolt or shaft through said aligned holes and through corresponding holes arranged in a piece integral with the railway axis (100).
- the outer side (22) of the first fork (2) is articulated to the railway axis (100) around an axis (E 2a ) that is contained in a plane transverse to said railway axis (100). This joint is rigid, since it only allows one degree of freedom.
- the inner side (21) of the first fork (2) has a central arm (21 1) essentially parallel to the branches (221) of the inner side (22).
- a central arm (21 1) essentially parallel to the branches (221) of the inner side (22).
- spherical ball joints (4) are fixed.
- each of these ball joints (4) comprises a spherical portion, for example essentially a hemisphere.
- the second fork (3) also has an inner side (31) and an outer side (32).
- the outer side (32) of the second fork (3) is similar to that of the first fork (2), and has two branches (321) essentially parallel and provided with respective aligned holes for their rotational coupling to the wheel ( 200).
- the coupling is carried out by means of a bolt (8) that passes through said holes and corresponding holes in a piece integral with the wheel (200).
- the outer side of the second fork (3) is thus also articulated to the wheel (200) about an axis (E 3a ) that is contained in a plane transverse to the axis of rotation of the wheel (200). This joint is also rigid, since it only allows one degree of freedom.
- the inner side (31) of the second fork (3) comprises two arms (31 1) essentially parallel to each other and parallel to the branches (321) of its outer side (32). These arms (311) have two aligned holes at their ends, and on the inner faces of said ends they are configured for the support of cups (5).
- Each cup (5) has an essentially spherical cavity that is complementary to the shape of the ball joints (4).
- These supports (6) basically have four parts or sections: a first section (61) that has a diameter designed to fit into a cylindrical cavity arranged on a face of the cup (5) opposite to that in which the cavity is located spherical; a second threaded section (62) that is fixed by means of a thread to the hole at the end of the corresponding arm (311); a third section (63) also threaded for the threaded fixing of a nut (7) for fixing the assembly; and a fourth section (64) located at the end and having a polygonal shape, so that it is possible to rotate the support (6) as a whole to properly locate the cup (5).
- this connection (1) allows a certain misalignment between the first fork (2) and the second fork (3).
- Fig. 5 shows a situation of this type where the axis (E 2b ) that passes through the hole at the end of the central arm (211) of the first fork (2) and the axis (E 3b ) that passes through the holes of the ends of the lateral arms (311) of the second fork (3) form an angle a. Therefore, this connection (1) allows the wheel (200) and the railway axle (100) to be misaligned when necessary depending on the stresses to which they are subjected during their useful life, thus avoiding breakage caused by fatigue loads. .
