Definitions

  • the area of application technique for the invention is transport systems for people and goods.
  • the "Guidance system for pneumatic undercarriages”, is intended within the area of transport of people and goods, to allow by means of forced guidance to form a convoy, said convoy being able to constitute as many cars as are required for the service to which propose.
  • the transport system that incorporates a forced guidance par excellence to date is the traditional rail system, in its different configurations: long-distance, interurban and urban trains (subways, trams, subways / light trains).
  • the main drawbacks found in the guidance systems that apply railway technology, and those that are solved with the new guidance system for pneumatic undercarriages, are:
  • the birrail system and flange wheel has very limited the overcoming of slopes in complicated orographies, inclined planes of minimum slope are exceeded.
  • the turning radii necessary for railway systems range from several kilometers required at high speed, at the minimum 40 meters that allow tram trains but at a very reduced speed.
  • the rail systems need the use of segregated platform of the rest of the transport systems or in the modalities of subways / light trains or trams, the greatest integration that can be achieved are reserved platforms with crossing preferences with the rest of the existing traffic.
  • Figure 3. General perspective view of the Mechanical Guidance System.
  • Figure 6. Plan view of the Guided Mechanical System.
  • the guidance system for pneumatic undercarriages allows the formation of convoys and increases the transport capacity of both people and goods. At the same time, the safety, reliability and comfort of transport are increased, thanks to the integration of several systems that are redundant, especially in the aspect of safety of people and cargo.
  • the system consists of 4 integrated and complementary sets, which together guarantee functionality and security in execution.
  • the track is composed of two sets:
  • This V ⁇ a (1) system substantially lowers the traditional double track used by rail systems, since it is simplified to a simple channel housed below the level of the vehicle's tread.
  • the platform used is exactly as traditionally used in the construction of all types of roads. Which allows us to share existing or new construction.
  • This set is the interface between the Track (1) and the vehicle. It also houses electronic readers that transmit trajectory information to the vehicle's direction and speed control system (10). Its main components are:
  • the longitudinal axis of the pilot pilot (28), at all times is oriented tangentially to the curves described by the Track (1), thanks to the four horizontal wheels (12) always maintain contact with the vertical walls of the U (5 ) of the track, because its axis is located on a Slider (18), prestressed towards the outside by means of an elastic Element. In this way, the rolling and the reading of the track path are guaranteed.
  • Clamping mechanism (8) It consists of:
  • Pilot Sleeve (14) this piece is the union between the Pilot Guide (9) and the Holding Mechanism (8).
  • Axis 1 (7) is housed there, allowing the rotation between the two by means of tapered bearings, which allow the axial and radial loads to which they are subjected.
  • This Mangueta joins the Arms (15 and 16) of the Mechanism by means of silentblocks, so that they are rotated with respect to the Mangueta (14), being able to attenuate vibrations in parallel.
  • the hinge has a double function. On the one hand it allows the rotation of the mechanism and the Pilot Guide (9) with respect to the Axis 2 (21) and on the other it rotates with respect to the Roll Axis (22), guaranteeing that the loss of parallelism of the beam of the front axle of the vehicle with respect to the ground, it is not transmitted to the Pilot Guide (9).
  • two silent blocks are inserted in the housings for Axis 2 (21).
  • Axis 2 231
  • It allows the union of the Axis 2 Sleeve (17) and the Hinge (19).
  • the Axis 2 is fixed in this housing by means of nuts on both sides to guarantee the packing of the assembly.
  • Hydraulic system for vehicle steering (24). It is a system with which we manage to translate the rotation of Axis 1 (7) to a hydraulic pressure that will act on the assisted steering mechanism of the vehicle, thus orienting its wheels. It is composed of a Distribution Valve (13) located on Shaft 1 (7), which is fed by the pressurized fluid from the pressure pump of the power steering system, has a fluid outlet to the reservoir of said system and two outputs-inputs that work in one direction or another depending on the rotation of Axis 1 (7) and that inject fluid into the bolt of the power steering system in the direction corresponding to the rotation of wheels to be produced.

  • the mechanical guidance system allows pneumatic rolling vehicles to form a convoy. Increasing the transport capacity offered to date by buses and trucks, but at a cost per unit of mobile material substantially lower than the rail mobile material. At the same time it allows the pneumatic undercarriage to save slopes and minimum turning radii, which are out of reach of the railway.

  • the sensors, meters and other elements for data acquisition are located in different parts of the vehicle, although the fundamentals are housed in the Mechanical Guidance System itself (2).

  • the necessary information of the track path (1) is obtained that serves to send the necessary path variations to control.
  • These meters send the accounts to the electronic control system through the data acquisition system.
  • the number of accounts represents a shift over a rotation point.
  • the number of accounts is 10,000 counts or pulses per revolution, which provides a resolution of 0.009 degrees / pulse.
  • the Electronic Direction and Speed Control System (3) has its starting position in the 0 ° position, for the two encoders mentioned in the previous paragraph. This implies that the position of the two Axes 1 (7) and 2 (21) located in the Holding Mechanism (8) are perfectly aligned with the longitudinal axis of the vehicle and therefore we are on a straight track path.
  • the path of the Track (1) it is reflected in the rotation of Axes 1 and 2, which in turn are read by the encoders, and these transmit the measurement to the Control who executes the precise orders, to the steering system, braking or acceleration of the vehicle to orient the wheels of the same according to the path of the road, and adapt its speed to the path to travel in the next meters.
  • Control communicates, in turn, with the Trajectory Anticipation System (4).
  • the Control contrasts the information available to both of them and at the same time the Path Anticipation System knows the orders that the Control is executing.
  • the Control with the information provided by the Trajectory Anticipation System, checks that the operation corresponds to the one suitable for the current and immediate future trajectory and speed.
  • the Control sends order for a controlled emergency stop. This may occur, for example, in the event that an obstacle appears in the path that the vehicle follows.
  • the orders sent by the Electronic Control are executed in the vehicle by means of actuators, composed of DC motors and gearboxes, and by means of electronics on the potentiometer that regulates the admission opening to accelerate the vehicle.
  • actuators composed of DC motors and gearboxes
  • electronics on the potentiometer that regulates the admission opening to accelerate the vehicle.
  • the trajectory anticipation system uses a laser viewfinder (27), located on the front of the first car of the convoy, which reads the path described by the Via, and has the necessary software for the interpretation of this information, its treatment and subsequent Shipping to Electronic Control.
  • the software allows communication with the Loop Control, guaranteeing the safety of the operation.
  • the laser viewfinder (27) reads at all times the real longitudinal axis of the Track (1), and transmits it to the Control. This provides the trajectory information several meters before the convoy reaches each point read. At the same time, it provides security to the operation as it identifies obstacles or other physical unforeseen events that appear on the path, immediately sending a Controlled Emergency Stop order to the Vehicle.
