Description
Technical field
The utility model relates to a kind of automobile brake system parts, relates in particular to a kind of braking adjusting-arm.
Background technique
The effect of braking adjusting-arm is that the break brake clearance is adjusted at present, refers to the gap between friction pairs of brake element brake drum and the brake lining is adjusted.Automobile in use, braking can cause the continuous wearing and tearing of braking member frequently, causes the gap increase in various degree between brake drum and the shoe plate, causes pedal travel lengthening, the decline of brake chamber thrust, braking retardation and braking force reduction etc.For guaranteeing the driving safety of vehicle, keep the equilibrium of working between the relatively stable of pedal travel and each break, need brake clearance is adjusted, play the function of regulation and control braking function and sensitivity.Traditional braking adjusting-arm comprises the braking adjusting-arm housing, adjustment mounting hole on the housing and the gear ring of adjusting setting in the mounting hole, adjust the mounting hole place on the adjustment arm housing and screw rod is set for the gear ring in the fastening adjustment mounting hole, when using this braking adjusting-arm to adjust braking gap, because gear ring fastening (the loosening meeting of gear ring automatic rotating affects the adjusting of braking gap) can't directly rotate gear ring adjustment, need to unclamp screw rod pulls down and adjusts arm and rotate the again fastening installation of one or several tooth, the adjustment braking gap is loaded down with trivial details, wastes time and energy.
The model utility content
The purpose of this utility model is to provide a kind of braking adjusting-arm that can directly rotate gear ring, when having solved traditional braking adjusting-arm adjustment braking gap, because can't directly rotate gear ring adjustment, need to unclamp screw rod pulls down and adjusts arm and rotate the again fastening installation of one or several tooth, the adjustment braking gap is loaded down with trivial details, the problem that wastes time and energy.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of braking adjusting-arm, comprise the adjustment mounting hole on housing and the housing, be provided with worm gear in the described adjustment mounting hole, gear ring is set in the worm gear, be provided with the worm shaft of nut in the housing near adjustment mounting hole place, worm shaft embeds housing, worm screw is set on the worm shaft, and worm screw and worm shaft cooperate, and are socketed with lock sleeve on the worm shaft, lock sleeve is positioned between the nut and housing of worm shaft, and lock sleeve engages with the nut of worm shaft.This braking adjusting-arm arranges worm shaft, worm and worm wheel, convenient by rotary worm axle drive worm screw during use, thereby worm screw drives worm gear and rotates, reach the purpose of rotary turbine ring gear, regulate gear ring adjusting braking gap thereby rotate, be socketed with lock sleeve between the nut of worm shaft and housing on the worm shaft, finish when regulating the nut snap lock worm shaft by lock sleeve and worm shaft, thereby indirectly lock gear ring, stablize the adjusting of braking gap, adjustment process is succinctly laborsaving, increase work efficiency, guarantee the accurate of adjusting.
As preferably, be socketed with spring on the described worm shaft, spring is positioned between lock sleeve and housing.By spring automatic reset, make the nut automatic fastening of lock sleeve and worm shaft, assurance is finished when regulating, and gear ring does not independently rotate, and guarantees the accurate of adjusting.
As preferably, be provided with oil nozzle in the described adjustment mounting hole and between the housing side.By oil nozzle is set, conveniently provide lubricated, guarantee the flexibility of rotating between worm gear and worm screw.
As preferably, be fixed with cover plate on the outside housing of described worm shaft and worm screw.By cover plate worm shaft and worm screw are fixed in the housing.
The beneficial effects of the utility model are: (1), this braking adjusting-arm arrange worm shaft, worm and worm wheel, and adjustment process is succinctly laborsaving, increases work efficiency; (2), be socketed with lock sleeve between the nut of worm shaft and housing on the worm shaft, guarantee to regulate accurately.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a kind of structural representation that another angle of the utility model is observed;
Among the figure: 1, worm gear, 2, oil nozzle, 3, lock sleeve, 4, worm shaft, 5, spring, 6, worm screw, 7, housing, 8, cover plate.
Embodiment
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described specifically:
Embodiment: as shown in Figures 1 and 2, a kind of braking adjusting-arm, comprise the adjustment mounting hole on housing 7 and the housing, adjust in the mounting hole and be provided with worm gear 1, gear ring is set in the worm gear, be provided with the worm shaft 4 of nut in the housing near adjustment mounting hole place, worm shaft embeds housing, and worm screw 6 is set on the worm shaft, worm screw and worm shaft cooperate, be socketed with lock sleeve 3 on the worm shaft, lock sleeve is positioned between the nut and housing of worm shaft, and lock sleeve engages with the nut of worm shaft, be socketed with spring 5 on the worm shaft, spring is positioned between lock sleeve and housing, adjusts in the mounting hole and between the housing side and is provided with oil nozzle 2, is fixed with cover plate 8 on the outside housing of worm shaft and worm screw.
When using, this braking adjusting-arm drives worm screw by the rotary worm axle, thereby worm screw drives worm gear and rotates, reach the purpose of rotary turbine ring gear, regulate gear ring adjusting braking gap thereby rotate, be socketed with lock sleeve between the nut of worm shaft and housing on the worm shaft, finish when regulating the nut snap lock worm shaft by lock sleeve and worm shaft, thereby indirectly lock gear ring, stablize the adjusting of braking gap, adjustment process is succinctly laborsaving, increase work efficiency, guarantee the accurate of adjusting.
Above-described embodiment is a kind of better scheme of the present utility model, is not that the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technological scheme that claim puts down in writing.
