Abstract

The invention discloses a hand-operated adjusting arm capable of completely locking an adjusting shaft and a worm. The hand-operated adjusting arm comprises a housing, a worm wheel, a worm, an adjusting shaft and a large spring, wherein a mounting hole is formed in the housing, the lower port of the mounting hole expands to form an enlarged part, two small steel beads are symmetrically fixed on the upper end face of the enlarged part, a ring-shaped protrusion is arranged at the lower end part of the adjusting shaft, a plurality of concave slots are formed in the ring-shaped protrusion, a threaded segment is tapped at the upper end part of the adjusting shaft, the large spring is sleeved on the part of the adjusting shaft at the upper end part of the mounting hole, the lower end face of the large spring is leaned against the upper end face of the worm, the adjusting shaft is provided with a threaded cap, and after the threaded cap is locked in place, the large spring compacts the worm statically and simultaneously the concave slots are tightly attached to the surfaces of the small steel beads. The hand-operated adjusting arm can lock the worm and the adjusting shaft in both the radial and the axial directions to achieve the purpose of two-way locking, so that the automobile brake system is more secure and safe. The hand-operated adjusting arm has simple structure and low manufacturing cost and is very convenient to operate.

Description

technical field [0001] The invention relates to a manual adjustment arm for adjusting the brake clearance of an automobile brake system, specifically a manual adjustment arm which can completely lock an adjustment shaft and a worm. Background technique [0002] With the improvement of people's quality of life and the needs of traffic development, cars have become more and more popular, and cars will inevitably vibrate and bump when driving, which often causes the adjustment arm to loosen, thereby affecting the braking effect of the car. Adjustment arm to adjust. [0003] At present, the manual adjustment arm of the automobile brake system used more in the market is to adjust the brake gap by installing springs, steel balls and plum blossom sleeves in the adjustment shaft to adjust and position the brake gap. , the big steel ball spreads out two small steel balls, and the small steel balls are inserted into the plum blossom sleeve to adjust and position the brake. Howeve...
