Self -lubricating type brake pedal mechanism

The utility model discloses a self -lubricating type brake pedal mechanism, including establishing the plug at the booster front end, establish the pedal arm between two plugs, the pedal arm passes through the bayonet lock to be fixed in the plug, seted up on the outer wall of bayonet lock along the axial waist connected in star of bayonet lock, the pedal arm with the waist connected in star corresponds the department and has seted up a perpendicular through -hole, lubricating grease is equipped with in the perpendicular through -hole, perpendicular through -hole inner with the outer wall contact, it is sealed that the sealed match of oil cup is passed through to perpendicular through -hole outer end. In this scheme, through the waist connected in star that adopts the bayonet lock to and the perpendicular oil duct of pedal arm, realized the self -lubricate of bayonet lock outer wall guaranteeing the timely replenishment of lubricating grease, prevent simultaneously that fluid from overflowing, guarantee the booster and stepped on the joining of plates reliability.
