ABSTRACT:
A brake system for an automobile comprises a planetary gear set, a clutch operating unit and an emergency braking unit. The planetary gear set is disposed between gear and clutch assemblies of the automobile and includes a bell-shaped casing with a central neck connected securely to an input shaft of the gear assembly. The bell-shaped casing has an annular wall portion with an internal thread therein, a sun gear disposed centrally in the casing and fixed to a clutch shaft of the clutch assembly which passes axially and centrally therethrough, and a planet gear which meshes with the internal thread of the casing and the sun gear. The planet gear has a planet shaft connected rotatably to a clutch shell of the clutch assembly. The clutch operating unit is actuated to unfasten the clutch shell from the clutch shaft while the emergency braking unit is operated to brake the clutch shell from rotating and permitting the casing to be rotated by the engine in a direction opposite to an original direction, thereby turning the wheel of the automobile in a rearward direction so as to stop the automobile from running forward, and to increase instantaneously an extra amount of fuel to the engine of the automobile to retain the engine in a functioning mode.
