Description
Technical field
The utility model relates to technical field of automobile, is specially a kind of braking adjusting arm housing.
Background technique
The effect of adjustment arm adjusts brake gap, refers to friction pairs of brake element---the adjustment that the gap between brake drum and brake lining is carried out.In use, braking can cause the continuous wearing and tearing of braking member to automobile frequently, causes the gap increase in various degree between brake drum and shoe plate, causes pedal travel lengthening, the decline of brake chamber thrust, braking retardation and braking force reduction etc.For ensureing vehicle driving safety, work between relatively stable and each break of maintenance pedal travel equilibrium, need adjust, play the function of regulation and control braking function and sensitivity to brake clearance.
At present, adjustment arm is in transmission process, the internal stress adjusting axis body and driving lever joint in adjustment arm housing is greater than when being applied to the driving force on adjustment arm housing, so easily there is slight crack or bend in each joint adjusted in arm, the phenomenon causing adjustment arm housing to occur scrapping occurs, reduce the working life of adjustment arm housing, thus reduce the utilization ratio of resource.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of a kind of braking adjusting arm housing that effectively can solve existing adjustment arm and in use easily occur slight crack.
For achieving the above object, the utility model provides following technological scheme: a kind of braking adjusting arm housing, comprise adjustment arm body, described adjustment arm body offers worm screw axis hole and blind hole, described worm screw axis hole comprises large diameter hole and small diameter bore, the hole depth of large diameter hole is identical with the hole depth of blind hole, described blind hole and large diameter hole partly overlap, described adjustment arm body comprises adjustment axis body and is connected to the driving lever on adjustment axis body, driving lever is in turning shape, the fixed base that driving lever comprises connecting rod and is connected with connecting rod, the joint of connecting rod and fixed base is provided with the first arc-shaped transition inclined-plane and the second arc-shaped transition inclined-plane, the joint of described adjustment axis body and driving lever is provided with the first strengthening rib and the second strengthening rib, first strengthening rib comprises arcuate flanks, arcuate flanks is tangent with the outer wall of adjustment axis body, described adjustment axis body is provided with circular adjustment axis hole and square through hole, the adjustment center line of axis hole and the centerline parallel of square through hole, adjustment axis hole and square through hole partly overlap, the center line of described worm screw axis hole and the center line of square through hole are at grade and vertical.
Further, described adjustment axis body is provided with several limiting through hole.
Further, the exterior contour of described second strengthening rib is triangle cylindricality, and described second strengthening rib comprises the first side and the second side, the first side laminating driving lever, the second side laminating adjustment axis body.
Contrast the deficiencies in the prior art, the beneficial effect that the technological scheme that the utility model provides is brought:
1. the utility model is protected by the first strengthening rib, is supported adjustment axis body and driving lever; again by design that arcuate flanks is tangent with adjustment axis body outer wall; increase the shearing stress of adjustment axis body and driving lever joint; make braking adjusting arm housing firmer; not easily there is slight crack; second strengthening rib effectively can be protected, support worm screw axis hole simultaneously, and phenomenon that is bending and distortion occurs effectively to prevent the hole wall of worm screw axis hole from occurring.
2. the utility model is by the first arc-shaped transition inclined-plane and the second arc-shaped transition inclined-plane, first arc-shaped transition inclined-plane and the second arc-shaped transition inclined-plane can strengthen the internal stress between connecting rod and fixed base, prevent adjusting arm and in use occur because driving force is excessive that the phenomenon of fracture occurs.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model gives prominence to the second strengthening rib.
Fig. 2 is the structural representation that the utility model gives prominence to the first strengthening rib.
Embodiment
With reference to Fig. 1-Fig. 2, the utility model braking adjusting arm housing embodiments is described further.
A kind of braking adjusting arm housing, comprise adjustment arm body 1, described adjustment arm body 1 offers worm screw axis hole 11 and blind hole 12, described worm screw axis hole 11 comprises large diameter hole 111 and small diameter bore 112, the hole depth of large diameter hole 111 is identical with the hole depth of blind hole 12, described blind hole 12 partly overlaps with large diameter hole 111, the driving lever 3 that described adjustment arm body 1 comprises adjustment axis body 2 and is connected on adjustment axis body 2, driving lever 3 is in turning shape, the fixed base 32 that driving lever 3 comprises connecting rod 31 and is connected with connecting rod 31, connecting rod 31 is provided with the first arc-shaped transition inclined-plane 33 and the second arc-shaped transition inclined-plane with the joint of fixed base 32, first arc-shaped transition inclined-plane 33 and the second arc-shaped transition inclined-plane can strengthen the internal stress between connecting rod 31 and fixed base 32, prevent adjusting arm and in use occur because driving force is excessive that the phenomenon of fracture occurs, adjustment axis body 2 is provided with the first strengthening rib 4 and the second strengthening rib 5 with the joint of driving lever 3, first strengthening rib 4 comprises arcuate flanks 41, arcuate flanks 41 is tangent with the outer wall of adjustment axis body 2, described adjustment axis body 2 is provided with circular adjustment axis hole 21 and square through hole 22, the adjustment center line of axis hole 21 and the centerline parallel of square through hole 22, adjustment axis hole 21 partly overlaps with square through hole 22, the center line of described worm screw axis hole 11 and the center line of square through hole 22 are at grade and vertical.
