Definitions
- the set position corresponds in some cases to a zero component of apparent gravity (resulting from earth's gravity and centrifugal acceleration due to the curve) according to the floor of the car, in others, it corresponds to a component capped in value of this same component, the criterion being always to minimize the effect on the traveler of the transverse accelerations parallel to the . vehicle floor, which in a way constitutes a spatial reference for the traveler placed inside the vehicle.
- the commercial interest of the tilting of the body is to improve the comfort of the traveler for given speeds in curves or even, for given comfort, to increase speeds in curves.
- 1st category the inclination of the body is obtained by means of mechanical parts connecting two solids of the vehicle and the sole purpose of which is to ensure the degree of freedom of rotation around the longitudinal axis: these are axes and bearings or a set of connecting rods.
- the relative rotational movement between these two aforementioned solids is obtained by these mechanical parts and the necessary energy supplied through jacks placed between the two solids in question.
- This type is the most widespread, and illustrated for example by documents DE-A-2001282 or GB-A-2079701;
- the invention is applicable to the two categories mentioned above, even if, for reasons of simplification, the following figures and comments will relate exclusively to the tilt systems according to the second category.
- the invention also relates to a phenomenon accompanying the increase in speed on winding lines which must be taken into account in conjunction with the inclination of the body when it is desired to effectively practice higher speeds on such lines.
- the observation which is made, and which is well known, comes from the fact that by increasing the speed in a given curve, the transverse forces transmitted to the track inevitably vary like the square of the speed. Apart from the stresses on the track itself, the rolling stock catches up with all the games available transversely, resulting in a degradation of comfort, as will be explained.
- the play in question has essentially two sources: the play of the axles in the rail and the play between stops of the secondary suspension.
- the primary suspension it is designed to have a certain stiffness conditioned by the stability and, generally having no stops, is not annoying.
- the force-applying member is a hydraulic member with reversible action from the energy point of view by taking or returning energy from or to at least one hydraulic accumulator.
- One of the two motor-pumps has a variable displacement, the variation of the displacement being controlled by the members for detecting and calculating the force to be applied.
- connection is made by two bushels depending on the direction of the signal delivered by the tr.aiteroent circuit so as to cause the desired rotational or transverse movements when the jack (s) must accelerate the movement of the body in a s -ens or in the other.
- the speed of rotation of the body is suitable, or else when the body does not undergo any significant effort on the part of the transverse jack, that is to say if the signal delivered by the treatment circuit is less than a fixed threshold, the jack (s) are isolated from the accumulator and the nurse and short-circuited thanks to the third bushel.
- transverse stabilization or the stabilization in rotation around the longitudinal axis of a railway body can be carried out in conjunction with a vertical movement damping system according to the device described in the application.
- the invention can be integrated into a system in which both the vertical movements and the horizontal movements are each subject to stabilization and therefore to damping.
- FIG. 1 is a cross section of a body of railway equipment, showing the location of the tilt stabilization jacks.
- FIG. 2 is a block diagram of the tilt control.
- FIG. 3 shows the operating diagram of a body stabilization inclined around the longitudinal axis combined with a vertical stabilization.
- Figure 5 is an operating structure of the lateral control.
- the accelerometric signal delivered by the accelerometer AO corresponds to a significant acceleration of the body directed towards the right (for example in a curve on the right)
- the jack 12 placed on the right of the body is put in compression while the jack 12 on the left is extended so as to compensate by the component of earth's gravity at least part of the centrifugal force.
- the situation is reversed when the transverse body acceleration itself changes direction.
- no order is given to the tilt cylinders.
- FIGS. A and 5 explain the device for controlling the lateral stabilization according to another aspect of the invention.
- the lateral stabilization servo shown in FIG. 5 is produced from the signal given by an accelerometer 1A with a horizontal sensitive axis fixed to the body.
- the accelerometric signal is processed in a processing circuit 18 possibly including a filter 20 (high pass), an integrator
