Definitions

  • the present invention concerns a side member for a heavy vehicle, in particular a heavy vehicle with, at least in part, electric traction.
  • the present invention finds its preferred, although not exclusive, application in electric traction trucks. Reference will be made to this application by way of example below.
  • Heavy vehicles such as trucks are more and more electrified in order to reduce the use of internal combustion engine in view of their polluting emissions.
  • the electrification foresees the presence of electrical machines configured to provide torque to the wheels of the vehicle and related batteries configured to store electrical energy to be used/provided by the electric machines.
  • the batteries are usually carried by the chassis of the vehicle and tends to occupy all the useful spaces. In view of the preceding, other elements such as inverters or electronic control unit needs to be displaced with respect to the batteries.
  • An aim of the present invention is to satisfy the above mentioned needs in a cost effective and optimized way.
  • Figure 1 is a perspective view of a portion of a chassis for a heavy vehicle according to the present invention.
  • Figure 2 is a perspective view of the portion of figure 1 together with an electric component of the heavy vehicle.
  • FIG. 3 is a lateral view of an alternative embodiment of the chassis according to the invention. Detailed Description of Preferred Embodiments of the Invention
  • Chassis 1 extends along a longitudinal axis A of the vehicle and comprises a first, left, side member 2 and a second, right, side member 3.
  • the two side members 2, 3 are advantageously symmetrically placed with respect to axis A and have the same cross-section.
  • such cross-section along axis A is C- shaped with the opening of the C-shape of one side member 2 faced to the opposite side member 3.
  • the side member 3 comprises a main portion 3' and a terminal portion 3'', i.e. a portion that is placed in a front or rear terminal edge of the main portion 3'.
  • Both the main and terminal portions 3', 3'' have a C- shaped cross section provided with a lateral wall 3a', 3a'', an upper wall 3b', 3b'' and a lower wall 3c', 3c''.
  • the upper wall 3b', 3b'' and lower wall 3c', 3c'' extends cantilevered from respective upper and lower edges of the lateral wall 3a', 3a'' towards the opposite side member 2.
  • both the main and the terminal portions 3’, 3" defines respective spaces 4, 5 that are respectively delimited vertically by upper walls 3b', 3b'' and lower walls 3c', 3c'', laterally delimited by lateral walls 3a', 3a'' and opened towards the respective side member 2, 3.
  • the upper and lower walls 3a'', 3b'' are parallel to each other.
  • such upper and lower walls 3a'', 3b'' extends at least for a longitudinal distance preferably comprised between 300 and 600 mm.
  • the upper wall 3b'' of the terminal portion 3’’ is continuous, i.e. at the same height with respect to the ground, of the upper wall 3b' of the main portion 3'.
  • the lower wall 3c'' of the terminal portion 3'' may be discontinuous with respect to the lower wall 3c', i.e. having a different height with respect to lower wall 3c' of the main portion 3'.
  • the lower wall 3c'' of terminal portion extends vertically closer with respect to the ground, i.e. space 5 is vertically wider with respect to space 4.
  • the upper and lower walls 3a'', 3b' are parallel with respect to an axis B that is inclined of an angle ⁇ with respect to longitudinal axis A in vertical direction.
  • angle ⁇ may be comprised between 10° and 12°, in the shown preferred embodiment 11°.
  • space 5 is suitable for house an electric component 6, such as an inverter, that may be fixed to the lateral wall 3a and/or upper and lower walls 3b" , 3c" .
  • an electric component 6 such as an inverter
  • fixation may be provided with any known means in the mechanical field, e.g. by screw, with omega brackets, via rubber-metal bearings, glued etc.
  • protective covers or damping means between the electric component 6 and the side member 3, 4 may be provided in addition.
  • the electric component 6 is electrically connected to batteries thanks to wire connections (not shown) that may be housed within space 4 of the main portion 3' until reaching batteries/electrical machines (not shown).
  • the terminal portion 3' may be realized as a separate element fixable to the main portion 3' or realized as one piece with the latter.
  • the terminal portion 3 may be realized in a different material with respect to the standard metallic material in which side members are realized.
  • the chassis is adapted to house an electrical component such as an inverter. In this way, such component is connected with short wire connection to related batteries and electrical machines.
  • the proposed housing provides a very strong fixation of the latter with high protection from damages due to collision with elements coming from the environment .
