Description
Technical field
The utility model relates to Brake for vehicle system, belongs to mechanical brake brake assembly technical field, is specifically related to a kind of self-regulated gap assembly that is exclusively used in draw-arm break.
Background technique
Braking system is the critical component that is related to safety of person vehicle, break belongs to most important safety, critical component in all moving vehicles, the braking system of automobile is divided into various structures form according to the requirement such as reliable, laborsaving, and draw-arm break is a kind of structure conventional in mechanical brake break.
In order to keep good retardation efficiency, between the friction plate in brake shoe assembly and brake drum, to there is a best clearance value.Along with friction disc wear, the gap between brake shoe assembly and brake drum increases, and need to have the device of an adjusting play.
Existing non-self-regulated draw-arm break, its slack adjuster comprises self-regulated plate and the ratchet cover plate, by stirring self-regulated plate, slide block is combined with the next tooth of the ratchet cover plate.This structure needs artificial moving tooth adjusting play, could meet safety traffic needs, often will be through adjusting and friction plate could be used to the limit for several times, and very trouble; The gap that veteran old driver adjusts may be more reasonable, and the gap that young driver recalls is probably not fully up to expectations.Institute's adjust the play is too small or at all very close to each other, and the consequence causing is to drag to stop, and moment of torsion, the oil consumption of meaningless increase vehicle are high, friction plate consumption fast, shorten the adverse effects such as vehicle service life; If the excesssive gap of adjusting, will increase brake petal and parking hand lever distance, likely cannot meet parking in action radius, there is potential safety hazard.
Model utility content
The utility model aims to provide a kind of self-regulated gap assembly that is exclusively used in draw-arm break, and when after friction disc wear, the optimum state is arrived in the gap that can automatically adjust between brake drum.
For this reason, the technological scheme that the utility model adopts is: a kind of self-regulated gap assembly that is exclusively used in draw-arm break, comprise the first assembling set (7) from left to right setting gradually, intermediate connector (8) and the second assembling set (9), described the first assembling set (7) supports fixture block (71) by first on the left of being positioned at and is positioned at support swivel nut (72) the one formation on right side, and be provided with left brake shoe clamping breach (71a) on the first support fixture block (71), described the second assembling set (9) supports fixture block (92) one formation by being positioned at the support unthreaded hole cover (91) in left side and being positioned at second of right side, and on the second support fixture block (92), be provided with right braking hoof and torque arm clamping breach (92a), described intermediate connector (8) is by the screw axis being from left to right connected successively (81), ratchet (82) and polished rod (83) one form, screw axis (81) and support swivel nut (72) screw-thread fit, polished rod (83) stretches into and supports in unthreaded hole cover (91).
The working principle that said structure is installed to after draw-arm break is such: when after friction disc wear, while needing parking, parking torque arm is rotated around torque arm pin under the effect of wire-pulling force, self-regulated plate and parking torque arm connect in aggregates by spring, and then rotate, the hook portion of self-regulated plate is mated with the ratchet at intermediate connector middle part, self-regulated plate drives ratchet to rotate, thereby drive the second support fixture block to move right, second supports fixture block promotion right braking hoof moves right, thus the length that has extended whole slack adjuster; Because the two ends of self-regulated gap assembly is by clamping breach and left and right brake shoe clamping, thereby realize the object in automatic adjustment friction plate and brake drum gap.In the time that the gap of friction plate and brake drum increases, when brake shoe released amount exceedes certain limit, stay cord is moved self-regulated plate and the position of the next indented joint of ratchet to, the rotation of drive intermediate connector, thereby the length that increases self-regulated gap assembly, moves brake shoe position, recover normal clearance.
The beneficial effects of the utility model are: avoided because of gap between brake shoe assembly and brake drum is too small or at all very close to each other caused dragging stop, the series of problems such as the vehicle torque of stopping brought increases, oil consumption is high, friction plate consumption fast because dragging, vehicle service life shortening; And the brake petal bringing because of excesssive gap and parking hand lever are apart from increase, guarantee vehicle parking in action radius, have improved driving safety.
