Description
Technical field
The invention belongs to auto parts apparatus technical field, particularly relate to a kind of auto automatic adjusting arm.
Background technique
In use, braking can cause the continuous wearing and tearing of braking secondary element to automobile frequently, causes the gap between brake drum and shoe plate to increase to some extent, 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 brake clearance.
Summary of the invention
The object of the invention is: the deficiency existed for prior art, provides the brake system of car automatic adjusting arm of a kind of sound construction, long service life.
For realizing the object of the present invention, be achieved by the following technical solutions: a kind of brake system of car automatic adjusting arm, include swing arm, swing arm one end is connected with control wheel joint, control wheel joint offers attachment hole, attachment hole is by a circular port and be positioned at circular port and jointly form by the rectangular opening of swing arm side, control wheel joint peripheral end face shape is identical with attachment hole, and attachment hole comprises middle post holes portion in the axial direction thereof and lays respectively at the cone hole part wide outside and narrow inside of post holes portion upper and lower end; Form an obtuse angle between the upper wall surface of control wheel joint outer side wall and lower wall surface, between upper wall surface and vertical direction, form the angle of 3 °, between lower wall surface and vertical direction, form the angle of 5 °; Control wheel joint and the outside of swing arm joint are provided with axis and swing arm, regulating wheel joint that attachment hole axis is all vertical, regulating wheel joint radial end face is rounded, and its upper wall surface at control wheel joint and lower wall surface crossover position place form the salient angle of radially evagination; Side away from regulating wheel joint between described control wheel joint and swing arm is connected with connecting plate, is provided with connecting wall between described control wheel joint and regulating wheel joint; Described swing arm end is semi circular surface, and swing arm is provided with two circular arc projections away from the side of regulating wheel joint, arc transition between two circular arc projections and swing arm side; The joint transitional surface of swing arm and control wheel joint, regulating wheel joint is concave circular arc shape.
Compared with prior art, the invention has the beneficial effects as follows: by this automatic adjusting arm, can ensure that each wheel drag has constant consistent brake clearance, make the braking of car load sensitiveer, balanced, effective, shorten stopping distance, even if each wheel drag shoe plate variable thickness causes, the degree of wear different, also can ensure the best efficiency braked, shorten reaction time, reduce compressed-air actuated consumption.
