ANÁLISE DO DISPOSITIVO MECÂNICO DIFERENCIAL

Abstract

The equipment connecting the wheels to the engine is a part on the rear axle (if the vehicle is a rear wheel drive) called the Differential, which distributes the torque generated by the engine to the transmission axles equally. In this work we try to expose from the idea of creating the differential until its internal operation. Although the creation of the differential was attributed to the french inventor Onesiforo Pecqueur in 1827 (workshop manager at the Conservatoire des arts et des arts in Paris), his application in a motor vehicle was in the early 1900s. Basically all differential components, except the differential case, are some kind of bevel gear. A basic differential consists of pinion, crown, satellites, planetary gears and differential box. Non-sports vehicles generally use the open differential. This applies the same torque on both rear wheels. Like any mechanical assembly the differential is not free from problems arising from the efforts generated by the transmission of the torque of the motor with the friction between the parts.
