Abstract
The utility model discloses a durable manual adjusting arm for fine adjustment of a brake system, which comprises a case, a worm, a worm pin and a twelve point socket, wherein the hexagonal nut end of the worm pin is drilled with a blind hole, the blind hole is provided with a compression spring, a big steel ball, small steel balls and a chock plug in turn; under the action of the compression spring, the big steel ball is propped against two small steel balls to lead the small steel balls to be clamped into the groove of the twelve point socket so as to lock the worm pin; the other end of the worm pin is provided with a ring groove; the case is provided with a stop pin hole; and when the stop pin hole is aligned to the ring groove, the stop pin is placed to fix the worm pin. As the design of the tooth sleeve and the stop shoulder, the axial movement of the worm is avoided, and the phenomenon of the shifting, unlocking and slipping of the worm and the like existing in the prior art is overcome.
Description
Technical field
The utility model relates to a kind of regulating device that brake system is finely tuned, especially a kind of durability hand regulation arm.
Background technique
At present, known hand regulation arm structure is to be assembled by housing, worm gear, worm screw, worm screw pin, cover plate, rivet and other accessories.Worm screw and worm screw pin often skids during the manual adjustment brake system, loses efficacy and make to adjust.
The model utility content
In order to overcome the above-mentioned defective of prior art, the utility model provides a kind of durability hand regulation arm, it comprises adjusts arm housing, worm screw, worm screw pin and plum-blossom sleeve, worm screw is installed in to be adjusted on the arm housing, the worm screw pin cooperatively interacts with worm screw and is connected, the external cylindrical surface of plum-blossom sleeve maintains static be pressed in the cylindrical hole of housing by interference after, six square nut ends of worm screw pin be drilled with blind hole, cylinder blind hole and with the perpendicular through hole of blind hole; Pressure spring, big steel ball, small ball and chock plug are housed in blind hole successively; Under the spring force effect of pressure spring, big steel ball withstands two interior small balls of groove that symmetry is installed in through hole and plum-blossom sleeve, make in its groove that snaps in plum-blossom sleeve respectively, thus locking worm screw pin; The other end at worm screw pin is provided with annular groove, and housing is provided with the retaining pin-and-hole, when retaining pin-and-hole and annular groove to put on time retaining pin fixedly worm screw sell.
As an optimized technical scheme of the present utility model, worm screw is sold the diameter that is slightly less than inner bore of worm with the worm screw section of matching diameter.
As another optimized technical scheme of the present utility model, the worm screw pin is provided with a plane of orientation with the worm screw place of matching, and inner bore of worm also is provided with an identical shaped cooperation plane.
Durability hand regulation arm of the present utility model is slightly less than the diameter of inner bore of worm owing to the adjustment axle and the diameter of the worm screw section of matching, can avoid interference fit, reduce and adjust axle and technological requirements such as worm screw material hot treatment, precision and tolerance, also without machinery such as press machine compacting assembling, and make hand assembled into, worm gear and adjustment axle can be not stuck, make the assembling process simple and easy to do, it is low to adjust arm assembly assembling scrappage, steel ball is snapped in respectively in the groove of plum-blossom sleeve, thus the locking worm shaft; Because the external cylindrical surface of plum-blossom sleeve maintains static be pressed in the cylindrical hole of housing by interference after, so durability hand regulation arm of the present utility model can keep stablizing when normal vehicle operation.The structural design of three hoodle unidirectional self-locks, coupling mechanism force are evenly distributed on two hoodles and lock, and make coupling mechanism force abundant.The tooth cover adds shoulder block design, avoids worm screw to move axially, and has overcome phenomenons such as present ubiquitous worm screw play, worm-lock incessantly skid.
