Abstract
The utility model relates to a dustproof sealing structure for a brake adjusting arm. The dustproof sealing structure comprises a shell, a worm gear and a worm, wherein the worm gear is accommodated in the shell; the worm is supported on the shell, and is matched with the worm gear; one end of the worm is extended from the shell, and a hexagon nut is arranged at the end; a dustproof mat is arranged on the inner side of the hexagon nut, and is pressed against the shell; and a sealing ring is arranged between the worm and the shell. According to the dustproof sealing structure for the brake adjusting arm, the dustproof mat and the sealing ring are pressed between the shell and the worm, so that the brake adjusting arm has high dustproof sealing performance, the penetration of silt and dust can be effectively prevented, and the service life of the product is prolonged.
Description
Technical field
The utility model relates to a kind of constituent elements of braking adjusting-arm, is specifically related to a kind of dust-proof sealing structure of braking adjusting-arm, belongs to technical field of automobile parts.
Background technique
Braking adjusting-arm is the important component part of motor vehicle braking system, the braking adjusting-arm of prior art is formed by the assembling of the parts such as housing, worm screw, worm gear and lining usually, and its concrete structure can be referring to shown in No. the 201020184022.5th, People's Republic of China's utility model patent.
Yet above-mentioned braking adjusting-arm is easy to infiltrate dust, silt in use owing to not having sealing configuration between worm screw and the housing, thereby easily weares and teares the interior part of housing, greatly reduces the working life of product.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of dust-proof sealing structure 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 is to provide a kind of dust-proof sealing structure that can effectively stop the braking adjusting-arm of silt, dust infiltration.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of dust-proof sealing structure of braking adjusting-arm, and it comprises housing, worm gear and worm screw; Wherein, described worm gear is contained in the housing; Described worm screw is supported on the housing, itself and worm wheel; Described worm screw is extended the outer end of housing and is provided with a hexagon nut, is provided with a dust-proof cushion in the inboard of hexagon nut, and this dust-proof cushion is connected on the housing; Between described worm screw and housing, be provided with seal ring.
The dust-proof sealing structure of braking adjusting-arm of the present utility model further is set to: be provided with a locating stud near the seal ring place between described worm screw and housing.
Compared with prior art, the utlity model has following beneficial effect: the dust-proof sealing structure of braking adjusting-arm of the present utility model is connected between housing and the worm screw by dust-proof cushion and seal ring are set, thereby make the dust sealing better performances of this braking adjusting-arm, can effectively stop the silt dust to infiltrate, prolong the working life of product.
Description of drawings
Fig. 1 is the structural representation of the dust-proof sealing structure of braking adjusting-arm of the present utility model.
Embodiment
See also shown in the Figure of description 1, the utility model is a kind of dust-proof sealing structure of braking adjusting-arm, and it is formed by a few part assemblings such as housing 1, worm gear 2 and worm screw 3.
Wherein, described worm gear 2 is contained in the housing 1.
Described worm screw 3 is supported on the housing 1, and it matches with worm gear 2 and realizes transmission.Described worm screw 3 is extended housing 1 an outer end and is provided with a hexagon nut 31, is provided with a dust-proof cushion 32 in the inboard of hexagon nut 31, and this dust-proof cushion 32 is connected on the housing 1.Between described worm screw 3 and housing 1, be provided with seal ring 4.
Further, be provided with a locating stud 5 near seal ring 4 places between described worm screw 3 and housing 1, this locating stud 5 can carry out axially locating with worm gear 3.
The dust-proof sealing structure of braking adjusting-arm of the present utility model is connected between housing 1 and the worm screw 2 by dust-proof cushion 32 and seal ring 4 are set, thereby make the dust sealing better performances of this braking adjusting-arm, can effectively stop the machine oil of the infiltration of silt dust and housing 1 inside to leak outside, prolong the working life of product.
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.
