"DISPOSIçãO EM VEìCULO COM FECHO DIFERENCIAL". Em um eixo entre duas rodas de acionamento (6, 7), um veículo a motor tem uma engrenagem diferencial que pode ser empregada para travar as duas rodas de acionamento uma com relação à outra. De modo a se reduzir a tensão à qual o fecho diferencial pode estar submetido, há um dispositivo (10) que, quando o fecho diferencial é engatado, detecta o ângulo relativo de rotação entre as rodas de acionamento e quando este atinge um valor marginal predeterminado, uma das rodas é freada por meio de uma unidade de controle (11) de modo a se limitar a rotação relativa entre as rodas. A roda externa é freada quando se move em uma curva. On a shaft between two drove wheels (6, 7), a motor vehicle has a differential gear, which has a differential lock that can be used to lock the two drive wheels relative to each other. To reduce the stress that the differential lock can be subjected to, there is a device (10) that, when the differential lock is engaged, senses the relative angle of rotation between the drive wheels and when this reaches a predetermined marginal value, one of the wheels is braked with the help of a control unit (11) in order to limit the relative rotation between the wheels. The outer wheel is braked when moving in a curve.
