Abstract: The present invention relates to the fields of mechanical and electronic engineering, focusing on energy efficiency on freight transport systems. More specifically, the invention applies to Long Combination Vehicles (LCV), in which the semi-trailer is provided with an auxiliary traction system, such as electric traction with regenerative braking, for example. The invention provides means for controlling the actuation of the auxiliary traction, which provides safe use and enhances economic and environmental savings in freight transport. In one embodiment, the invention provides a system for managing the auxiliary traction on a road implement that provides improved, safer drivability of the set.

Abstract: A process for manufacturing a friction material and an inorganic liquid binder for use in manufacture of friction materials. The process for the friction material makes use of a liquid binder that provides the performance of process steps with significant reduction in temperature, pressure and manufacturing time, making the process more energy efficient. The process also includes manufacturing a liquid binder that allows the use of different types of inorganic precursors with crystalline and/or amorphous features, through a mechanical activation process of the inorganic precursor. The process pertains to the fields of chemical engineering, mechanical engineering, materials engineering, focused on the area of friction materials for vehicle brake systems.

Abstract: A commercial automotive vehicle, such as trucks and buses, having an auxiliary shaft associated with an auxiliary engine, a coupling and/or uncoupling device and a method for controlling the coupling and/or uncoupling between a shaft of commercial automotive vehicles and an auxiliary engine associated with the shaft. Specifically, the vehicle has a device that couples and/or decouples the effects of at least one auxiliary engine to a shaft, allowing that, in a coupled state, the shaft receives auxiliary traction from the auxiliary engine or the auxiliary engine acts as a generator of braking energy in a regenerative way and, in a decoupled state, it allows the shaft to rotate freely so that no energy losses occur due to friction of the device components.

Abstract: A multifunctional supporting rod of vehicle components of commercial vehicles, such as road implements, including, e.g., rods useful in supporting of vehicle components like fender, wings, rearview mirrors, lighting devices for commercial vehicles and similar, among other parts. In one aspect, the rod includes an integrated shock absorber for vibrational efforts and load in rod itself, comprising structural composite material, which provides improved dampen of mechanic-dynamic efforts and improved mechanic responses, reducing structural fatigue. In other aspect, the rod provides higher resistance to efforts, less material amount, and provides a mode of incomplete failure in predetermined location, avoiding loss of components during a structural failure generated from use. In another aspect, the rod has low weight/mass, provides gain of payload of commercial vehicle, and economy of energy/fuel.

Abstract: An electric drive unit having an electric motor having a flange-mounted adapter that is attached to the electric motor and has a motor shaft extension for extending the motor shaft through the adapter. The electric drive unit has at least one sensor for measuring at least one operating variable of the electric motor and an evaluation unit for evaluating the operating variable(s) measured by the sensor(s). The sensor(s) and evaluation unit are arranged in and/or on the electric motor and/or adapter. The evaluation unit is designed to evaluate the measured operating variable(s) with respect to the need for maintenance and/or repair and to output a signal about the need for maintenance and/or repair via a signal transmission device for signaling the need for maintenance if the result of the evaluation of the operating variable(s) indicates the need for maintenance.
