Abstract
The utility model relates to a worm improvement structure of a brake adjuster, which comprises a rob body part and a hexagonal nut arranged on one end of the rod body part, wherein a plurality of locating grooves are arranged on the surface of the other end of the rod body part at equal intervals and extend along the axial line of the rod body part. The locating grooves of the worm improvement structure of the brake adjuster do not damage the whole surface of the rod body part, and thus a worm has high structure strength and good coaxiality.
Description
Technical field
The utility model relates to a kind of constituent elements of braking adjusting-arm, is specifically related to a kind of worm screw structure-improved of braking adjusting-arm, belongs to technical field of automobile parts.
Background technique
Braking adjusting-arm is the important component part in the motor vehicle braking system, and the braking adjusting-arm of prior art is formed by component assembles such as housing, worm screw, worm gear and linings usually.
The worm structure of prior art sees also shown in the Figure of description 1, and this worm screw comprises a rod body part 1 ' and the hexagon nut 2 ' that is positioned at rod body part 1 ' one end.For with this worm screw location, be provided with a circle locating slot 3 ' in the rod body part 1 ' the other end, this locating slot 3 ' rod body part 1 ' diameter reduces, and makes easily rod body part 1 ' bending, causes the coaxality of worm screw relatively poor; Simultaneously, also cause the structural strength of worm screw relatively poor.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of worm screw structure-improved with structure improved braking adjusting-arm, to overcome described defective of the prior art.
The model utility content
For addressing the above problem, the purpose of this utility model be to provide a kind of structural strength height and coaxality good the worm screw structure-improved of braking adjusting-arm.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of worm screw structure-improved of braking adjusting-arm, the hexagon nut that it comprises rod body part and is arranged at rod body part one end, equally spacedly in the other end of described rod body part surface be provided with some positioning grooves, described positioning groove is along the Axis Extension of rod body part.
The worm screw structure-improved of braking adjusting-arm of the present utility model further is set to: be provided with a pad in the joint of described hexagon nut and rod body part.
The worm screw structure-improved of braking adjusting-arm of the present utility model also can be set to: described positioning groove is specially 4.
Compared with prior art, the utlity model has following beneficial effect: the structure improved positioning groove of the worm screw of braking adjusting-arm of the present utility model is with whole rod body part surface breakdown, thereby makes worm structure intensity height and coaxality good.
Description of drawings
Fig. 1 is the schematic representation of worm screw of the braking adjusting-arm of prior art.
Fig. 2 is the structure improved schematic representation of the worm screw of braking adjusting-arm of the present utility model.
Embodiment
See also shown in the Figure of description 2, the utility model is a kind of worm screw structure-improved of braking adjusting-arm, and it is comprised of rod body part 1 and several parts such as hexagon nut 2 of being arranged at rod body part 1 one ends.Wherein, described rod body part 1 and hexagon nut 2 are integrated formed structure.
11 equally spacedly are provided with some positioning grooves 3 in the other end of described rod body part 1 surface, and namely Free surfaces 11 connects between the positioning groove 3.Described positioning groove 3 is specially 4, and it is along the Axis Extension of rod body part 1.
Further, described rod body part 1 and hexagon nut 2 are integrated formed structure, are provided with a pad 4 in the joint of described hexagon nut 2 and rod body part 3, need not when mounted to join in addition pad, thereby have made things convenient for installing and using of this worm screw.
The structure improved positioning groove 3 of the worm screw of braking adjusting-arm of the present utility model destroys whole rod body part 1 surface 11, thereby makes worm structure intensity height and coaxality good.
Above embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within make any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
Claims (3)
1. the worm screw structure-improved of a braking adjusting-arm, the hexagon nut that it comprises rod body part and is arranged at rod body part one end, it is characterized in that: equally spacedly in the other end of described rod body part surface be provided with some positioning grooves, described positioning groove is along the Axis Extension of rod body part.
