AI Technical Summary

Technical Problem

Existing commercial motor vehicles with auxiliary electric axles experience energy loss and increased fuel consumption due to friction in the gear systems when the coupling is maintained on flat sections, interfering with drivability and efficiency.

Method used

A coupling and uncoupling device for auxiliary motors in commercial vehicles, using a free differential assembly that engages or disengages the auxiliary motor with the axle based on control system signals, ensuring synchronized operation with the vehicle's conditions to avoid interference and optimize energy use.

Benefits of technology

The device ensures safe and efficient operation of auxiliary traction and regenerative functions without affecting vehicle drivability, reducing energy loss and fuel consumption by allowing the system to rotate freely when not in use.

Abstract

The present invention describes a commercial motor vehicle, such as trucks and buses, comprising an auxiliary axle associated with an auxiliary motor, a coupling and / or uncoupling device, and a method for controlling the coupling and / or uncoupling between an axle of a commercial motor vehicle and an auxiliary motor associated with the axle. Specifically, the present invention comprises a device that couples and / or uncouples the effects of at least one auxiliary motor to an axle, allowing, in the coupled state, the axle to receive auxiliary traction from the auxiliary motor or for the auxiliary motor to act as a regenerative braking energy generator, and, in the uncoupled state, allowing the axle to rotate freely so that no energy losses due to friction of the device components occur. The present invention falls within the field of mechanical engineering, focused on the area of ​​solutions for commercial vehicles for transporting cargo and passengers.
