Abstract
The invention relates to a gear-worm assembly for a brake adjusting arm. The gear-worm assembly for the brake adjusting arm comprises a housing, a worm gear, a worm, steel balls, a spring and a cover board, wherein the worm gear and the worm are accommodated inside the housing; the worm gear is matched with the worm; one end of the worm is axially provided with a plurality of arc grooves; the steel balls are accommodated inside the arc grooves; the cover board threadedly covers the housing; the spring is connected between the steel balls and the cover board in an abutting mode. According to the gear-worm assembly for the brake adjusting arm, the steel balls and the spring radially abut against the worm, so that worm motion can be effectively avoided, further stable operation of a brake system can be achieved and noise can be effectively reduced.
Description
Technical field
The present invention relates to a kind of constituent elements of braking adjusting-arm, be specifically related to a kind of braking adjusting-arm worm and gear assembly, belong to technical field of automobile parts.
Background technique
Braking adjusting-arm is the important component part in motor vehicle braking system, and the braking adjusting-arm of prior art is formed by parts assemblings such as housing, worm screw, worm gear and linings conventionally.
The worm screw of above-mentioned braking adjusting-arm is supported on housing conventionally, and itself and worm gear coordinate.Yet, owing to there is matching gap between worm screw and housing, easily cause worm screw play, and produce noise.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of structure improved braking adjusting-arm worm and gear assembly that has, to overcome described defect of the prior art.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of braking adjusting-arm worm and gear assembly that can effectively avoid worm screw play.
For achieving the above object, the technological scheme that the present invention takes is: a kind of braking adjusting-arm worm and gear assembly, and it comprises housing, worm gear, worm screw, steel ball, spring and cover plate; Wherein, described worm gear, worm screw are contained in housing; Described worm gear coordinates with worm screw; There are some arc grooves described worm screw one end along its axial distribution; Described steel ball is contained in arc groove; Described cover plate is screwed together on housing; Described spring is connected between steel ball and cover plate.
Braking adjusting-arm of the present invention is further set to worm and gear assembly: described steel ball is specially 2, and it is symmetrically distributed in the both sides of worm screw.
Braking adjusting-arm of the present invention is further set to worm and gear assembly: the diameter of described arc groove is identical with the diameter of steel ball.
Compared with prior art, the present invention has following beneficial effect: braking adjusting-arm of the present invention is radially supported worm screw with worm and gear assembly by steel ball and spring, thereby can effectively avoid worm screw play, make brake system stable, and effectively reduce noise.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of worm and gear assembly for braking adjusting-arm of the present invention.
Fig. 2 is the schematic diagram at another visual angle of worm and gear assembly for braking adjusting-arm of the present invention.
Fig. 3 is the schematic diagram of the worm screw of worm and gear assembly for braking adjusting-arm of the present invention.
Embodiment
Refer to Figure of description 1 to shown in accompanying drawing 3, the present invention is a kind of braking adjusting-arm worm and gear assembly, and it is formed by a few part assemblings such as housing 1, worm gear 2, worm screw 3, steel ball 4, spring 5 and cover plate 6.
Wherein, described worm gear 2, worm screw 3 are contained in housing 1, and described worm gear 2 coordinates with worm screw 3 and realizes transmission.
Described worm screw 3 is supported on housing 1, and there are some arc grooves 31 its one end along its axial distribution.Described steel ball 4 is contained in arc groove 31.In the present embodiment, described steel ball 4 is specially 2, and it is symmetrically distributed in the both sides of worm screw 3.
Described cover plate 6 is screwed together on housing 1.Described spring 5 is connected between steel ball 4 and cover plate 6, and it is connected on worm screw 3 steel ball 4 and avoids worm screw play.Further, the diameter of described arc groove 31 is identical with the diameter of steel ball 4, thereby both are coordinated closely.
Braking adjusting-arm of the present invention is radially supported worm screw 3 with worm and gear assembly by steel ball 4 and spring 5, thereby can effectively avoid worm screw play 3, makes brake system stable, and effectively reduces noise.
Above embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation within all spirit in this creation and principle.
