Abstract
The utility model discloses a brake adjusting arm which can be assembled and disassembled conveniently. The brake adjusting arm comprises a shell, a worm and a worm shaft arranged on the shell. The utility model is characterized in that the worm shaft and the worm are connected by adopting splines; the installation position of the worm is arranged in the shell; the worm shaft threads into the worm from one side of the shell; and the worm shaft is connected with the shell by adopting pins. The brake adjusting arm which can be assembled and disassembled conveniently is designed to be mounted in a detachable way, and changes the prior onetime press-in installation, which prevents the overall brake adjusting arm from being rejected due to quality factor, thus bringing significant convenience to the subsequent maintenance and replacement of components. Although the process difficulty is increased, the product quality is improved in respect of the overall processing course.
Description
Technical field
The utility model relates to automotive field, and specifically a kind of novel break is adjusted arm configuration.
Background technique
At present, being connected of old structure worm screw and worm shaft be to press-fit formation, like this worm screw and worm shaft formed one by interference fit, thus make this part with adjust arm housing and also can't break away from, form disposable use, cause non-exchange defective.
In addition, under this cooperation,, make this structure also breed two kinds of hidden dangers because worm screw and worm shaft exist error in the technique for manufacturing batch process.One when the tension that cooperates can cause the aggravation of worm screw internal stress, can cause the worm screw breakage relatively more frequent with impacting in the working environment, the arm stuck phenomenon can occur adjusting; Its two, when cooperating pine that worm screw and worm shaft are come off, the arm skidding can appear adjusting.These two kinds of quality accident potential are breakneck.
Summary of the invention
The utility model provides a kind of just reassembling type break to adjust arm at the deficiency of prior art.
Below introduce structure of the present utility model in detail, a kind of just reassembling type break is adjusted arm, comprises housing and the worm screw and the worm shaft that are installed on the housing, and worm shaft adopts spline to be connected with worm screw; The mounting point of worm screw is set in the housing, and worm shaft penetrates worm screw from housing one side, and worm shaft adopts pin to connect with being connected of housing.
Optimally, an end of described worm shaft is provided with a circle groove, and the cross section arc diameter of this groove just in time matches with the diameter of pin, on the housing end face pin-and-hole is set, and the center of this pin-and-hole is consistent with the groove cross section center of arc of worm shaft.
The utility model has the advantages that this just the reassembling type break adjust arm and be designed to dismountable installation and given up in the past in the past forced disposable installation, avoided causing whole scrapping because of quality factor.For later maintenance with change component and brought very big convenience.Although increased technology difficulty, promoted quality of product from integral body processing.
Description of drawings
