The invention discloses a torque protector of a differential mechanism, and the torque protector can cause the differential mechanism can enable the different mechanism to return to normal without dismounting a shell and replacing parts. The torque protector comprises the shell, an end cover, an end wall and a core shaft, wherein one end of the shell is provided with the end wall, an opening at the other end of the shell is provided with the end cover, the end wall is movably arranged at the shell in a penetrating manner, and the core shaft is used for installing the input shaft of the differential mechanism and arranged on the end cover; a push pedal and a press plate are movably arranged at the interior of the shell and around the core shaft, the shell is also internally provided with an elastic pushing mechanism which is matched with the push end of the push pedal and an elastic propping mechanism which is matched with the propping end of the press plate; and the core shaft is provided with an opening which is mutually wedged with the locking end of the push pedal, the outside of the locking end is provided with a locking step which is matched with the propping end of the pressplate, and the reset end, opposite to the press plate, of the shell is provided with a reset screwed hole. The torque protector provided by the invention has the advantages of greatly facilitating the maintenance of the differential mechanism, and realizing the zero cost of the maintenance.
Description
technical field [0001] The present invention relates to a differential, in particular to a torque protection device for a differential. Background technique [0002] At present, the structure of a torque protection device for a differential generally includes: a housing and a mandrel movably penetrated in the housing for installing the input shaft of the differential, and a protective pin is arranged between the mandrel and the housing. In actual use, when an abnormality occurs and the torque of the mandrel is too large, the differential and related transmission equipment are protected by breaking the protection pin so that they will not be damaged. The purpose of protecting the differential and related transmission equipment is achieved, but after eliminating the abnormal faults, it is necessary to open the casing and replace the protection pins to restore the differential to normal. The maintenance cost is high and maintenance is troublesome. Contents of the invention ...
