Cause spring 1007 not lie directly against worm shaft 1, substantially reduce thrust of the spring 1007 to worm shaft 1, together
When, the left end of spring 1007 props up spring shim 1008, right-hand member screw lid 1 screws in compression, causes spring 1007 to deform,
Thrust of the spring 1007 to worm shaft 1 is substantially reduced, reduces brake clearance precision, worm shaft 1 of also having decayed
Torsion transmission.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of reinforced brake clearance of housing
Automatic adjusting arm, including housing, worm shaft, pagoda spring, screw lid, the worm gear upper end connecting worm axle of housing, worm shaft are right
End sets connecting shaft, and connecting shaft right-hand member sets the axis of guide, and the axis of guide is located in the screw of housing after worm shaft is connected with housing, pagoda bullet
Spring loads in screw, and the inner ring of pagoda spring is enclosed on the right side that the axis of guide is outer, end face props up connecting shaft, screw lid and screw spiral shell
Connect, the screw bottom of housing sets circular arc, and the utility model housing screw bottom has set circular arc, greatly reinforced at housing screw
Intensity, spring shim and spring are eliminated, lie directly against worm shaft with pagoda spring end face, improve brake clearance precision, together
When penetrated with the axis of guide of worm shaft in pagoda spring, also solve the problems, such as pagoda spring compressive deformation, greatly strengthen pair
The thrust of worm shaft, also enhance the moment of torsion transmission of worm shaft.
To reach above-mentioned purpose, the technical solution of the utility model is：The reinforced arm for automatically regulating clearance of brake of housing, bag
Housing, worm shaft, pagoda spring, screw lid, the worm gear upper end connecting worm axle of the housing are included, the worm shaft right-hand member sets company
Spindle, the connecting shaft right-hand member set the axis of guide, and the axis of guide is located in the screw of housing after worm shaft is connected with housing, the pagoda
Spring loads in screw, and the inner ring of pagoda spring is enclosed on the right side that the axis of guide is outer, end face props up connecting shaft, the screw lid with
Screw is spirally connected.
Further set, the screw bottom of the housing sets circular arc.
Further set, the medial surface of the screw lid props up the other end of pagoda spring.
The beneficial effects of the utility model are：The utility model housing screw bottom has set circular arc, has greatly reinforced housing
Intensity at screw, eliminates spring shim and spring, lies directly against worm shaft with pagoda spring end face, improves brake clearance
Precision, while penetrated with the axis of guide of worm shaft in pagoda spring, also solve the problems, such as pagoda spring compressive deformation, increase greatly
The strong thrust to worm shaft, also enhance the moment of torsion transmission of worm shaft.
