Definitions
- the present specification refers, as its title indicates, to a suspended low-floor vehicle intended for urban collective transport, which has significant advantages over existing low-floor vehicles.
- low-floor buses are known for urban buses, characterized in that they have the floor at the same level as conventional sidewalks, thus facilitating access to all citizens, both the elderly, people with reduced mobility , including among them people with packages, luggage, small children, etc., like the rest of the users, and because a significant proportion of its interior surface does not have steps, so that once the passenger climbs into his stirrup Through an access door, it is possible to move inside to an exit door without having to save height differences.
- a model of a low-floor bus is known whose platform or low floor extends horizontally from the first doors to the central ones, leaning from them and to the end with a slight slope, placing the access step of both entrances at a height of 320 mm above the street plan.
- the vehicle's engine is mounted longitudinally on the left side of the upper part of the chassis, with a small incline.
- other devices such as the fuel tank, cooling system, lubrication tank, etc., are distributed either at the rear or at the bottom of the bus.
- the seats located above the engine and the rear axle require a pedestal to properly position them, hindering and / or preventing their use by older people and people with disabilities or, in general, with reduced mobility.
- the optional addition of a rear door means that it must have two access steps, which also makes it difficult and / or prevents its use by older people and people with disabilities or, in general, with reduced mobility.
- the purpose of the present invention is to provide a low-floor bus vehicle intended for urban collective transport, which, complying with current regulations for urban collective transport, allows effectively remedying the shortcomings that presently existing low-floor buses present, thus facilitating its use by older people, people with disabilities or, in general, with reduced mobility.
- the low-floor suspended vehicle intended for urban collective transport object of the present invention is constituted by a lattice structure specially designed for the location of most of the mechanical elements of the vehicle at the top of its structure, that is, in the the ceiling.
- the structure of the vehicle object of the invention breaks with the traditional lower lattice structure, to place it on the upper side of the bus structure, whereby all the integral elements of the bus hang from the upper lateral structure making a spatial assembly.
- an angle of entry of the vehicle defined as the angle formed by the horizontal line and the continuous imaginary line that extends towards the front of the vehicle without cutting its chassis, drawn by joining the support point of the front axle tires on the horizontal and the lowest point on the front of the vehicle; an angle of exit of the vehicle, defined as the angle formed by the horizontal line and the continuous imaginary line that extends towards the rear of the vehicle without cutting its chassis, -traced by joining the support point of the rear axle tires on the horizontal and the lowest point on the back of the vehicle; and an interior angle of the vehicle, defined as the angle formed by the horizontal line and the imaginary line drawn by joining the support point of the front axle tires on the horizontal and the lowest point of the middle part of the vehicle, of suitable values for access to the workshops and garages of the fleet and maintenance, as well as for the circulation of
- a structure of left side, right side, front, rear, floor and roof has been designed, which meets the structural resistance for the states of load and projected services, constituted by a series of vertical, horizontal and diagonal pillars, as well as a structure in lateral upper lattice.
- a series of basic pillars for the support of the elements located in the upper part of the vehicle, which are evenly distributed on the left and right sides of the vehicle.
- the front and rear approach angles, as well as their free heights, that is, the dimensions of the remaining gap between the ground and the lower point of the vehicle body, are the characteristics most important geometric that define the maneuverability of the bus.
- the low-floor suspended vehicle intended for urban collective transport object of the present invention thanks to the location of many of its elements in the upper part of the vehicle, it is possible to extend the dimensions of the remaining space between the ground and the lower point of the body of the vehicle, enabling the use of the vehicle for most of the route, including those points that include significant changes in the slope of the surface at one of the points of the route, also allowing the use of most of the garages designed for conventional buses.
- the front and rear approach angles, or entry and exit angles, as well as an interior angle, located in the central part are the characteristics most important geometric that define the maneuverability of the bus.
- the location of the propellant group is such that it does not represent a significant decrease in the useful area of passengers.
- the engine is installed across the rear of the bus object of the present invention, being located in a compartment separated from the cabin by a partition, thus allowing all vehicle access doors to be at the same height.
- the dimensions of the anterior and posterior axes define the minimum width of the inner aisle.
- the non-standard design of these axles in the low-floor suspended vehicle intended for urban collective transport object of the present invention results in a wider wheelbase, thus defining an interior aisle of sufficiently large dimensions to enable any traveler, including elderly people, disabled people or, in general, with reduced mobility, and, in particular, wheelchair users, can access the bus through an entrance door, located, for example, in the front of the vehicle , and exit through another door other than exit, located, for example, in the central and / or rear part of the vehicle, thus existing a single flow of passengers common to all users of the bus object of the present invention, avoiding, in this way, incurring discrimination against people with disabilities or, in general, with reduced mobility, and, in particular, chair users of wheels, in relation to other users.
- the remaining components, mechanical or not, of the low-floor suspended vehicle intended for urban collective transport object of the present invention are based on currently existing components, widely tested, adapted to comply with current regulations regarding collective transport urban.
- the low-floor suspended vehicle intended for urban collective transport object of the present invention can be equipped with a kneeling mechanism belonging to the damping system to get the vehicle to lean laterally or descend a few centimeters.
- the entry and / or exit doors of the vehicle object of the present invention can optionally be provided with retractable and adjustable ramps in their deployment, of a suitable slope to the dimensions and location of the center of gravity of the chairs of wheels, since, as is known, wheelchairs have a short wheelbase and the center of gravity is located at the rear, thus conditioning the maximum inclination of the ramp.
