Abstract
The utility model relates to a worm gear and worm assembly for a brake adjusting arm. The worm gear and worm assembly comprises a shell, a worm gear, a worm, steel balls, springs and a cover plate, wherein the worm gear and the worm are accommodated in the shell, and are matched; a plurality of circular grooves are axially distributed at one end of the worm; the steel balls are accommodated in the circular grooves; the cover plate is screwed with the shell; and the springs are pressed between the steel balls and the cover plate. According to the worm gear and worm assembly for the brake adjusting arm, the steel balls and the springs are radially pressed against the worm, so that the play of the worm can be effectively avoided, a brake system can run stably, and noise can be effectively reduced.
Description
Technical field
The utility model relates to a kind of constituent elements of braking adjusting-arm, is specifically related to a kind of braking adjusting-arm worm and gear assembly, 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 screw of above-mentioned braking adjusting-arm is supported on the housing usually, and itself and worm gear cooperate.Yet, owing to have matching gap between worm screw and the housing, cause easily the 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 defective of the prior art.
The model utility content
For addressing the above problem, the purpose of this utility model is to provide a kind of braking adjusting-arm worm and gear assembly that can effectively avoid the worm screw play.
For achieving the above object, the technological scheme that the utility model is taked 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 the housing; Described worm gear cooperates with worm screw; Described worm screw one end has some arc grooves along its axial distribution; Described steel ball is contained in the arc groove; Described cover plate is screwed together on the housing; Described spring is connected between steel ball and the cover plate.
Braking adjusting-arm of the present utility model further is set to the 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 utility model further is set to the worm and gear assembly: the diameter of described arc groove is identical with the diameter of steel ball.
Compared with prior art, the utlity model has following beneficial effect: braking adjusting-arm of the present utility model is radially supported worm screw with the worm and gear assembly by steel ball and spring, thereby can effectively avoid the worm screw play, make brake system stable, and effectively reduce noise.
Description of drawings
Fig. 1 is the schematic representation that braking adjusting-arm of the present utility model is used the worm and gear assembly.
Fig. 2 is the schematic representation that braking adjusting-arm of the present utility model is used another visual angle of worm and gear assembly.
Fig. 3 is the schematic representation that braking adjusting-arm of the present utility model is used the worm screw of worm and gear assembly.
Embodiment
See also Figure of description 1 to shown in the accompanying drawing 3, the utility model 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 the housing 1, and described worm gear 2 cooperates with worm screw 3 and realizes transmission.
Described worm screw 3 is supported on the housing 1, and the one end has some arc grooves 31 along its axial distribution.Described steel ball 4 is contained in the 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 the housing 1.Described spring 5 is connected between steel ball 4 and the cover plate 6, and it is connected on the worm screw 3 steel ball 4 and avoids the worm screw play.Further, the diameter of described arc groove 31 is identical with the diameter of steel ball 4, thereby both are cooperated closely.
Braking adjusting-arm of the present utility model is radially supported worm screw 3 with the 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 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.
