Abstract
The utility model relates to an automobile brake clearance adjusting arm capable of quickly, effectively and reliably adjusting an automatic brake clearance and having a self-lock function; the automobile brake clearance adjusting arm comprises a manual adjusting arm; an adjusting shaft for adjusting an arm shell in the manual adjusting arm is positioned in an adjusting shaft hole; a screw rod sleeve is sheathed on the adjusting shaft and is meshed with a worm wheel; the lower part of the adjusting shaft is connected with a base through a small tension spring; a gear is sheathed at the upper part of the adjusting shaft and is matched with a push rod; and a large tension spring is sheathed on a non-tooth part between the screw rod sleeve and the gear. The automobile brake clearance adjusting arm has the advantages of ensuring the effective, stable and reliable work of the manual adjusting arm, and being labor-saving and convenient for adjusting.
Description
Technical field
The utility model relate to a kind ofly can carry out fast vehicle brake gap, effectively, the reliable adjustment, have the automatic braking-gap regulation arm of auto-lock function again, belong to automobile component and make the field.
Background technique
CN1959142A, title " automatic braking-gap regulation arm ", comprise the adjustment arm housing, be located at intermeshing worm gear and the worm screw adjusted in the arm housing, also be provided with the adjusting bolt in the housing, the adjusting bolt passes worm screw and its outer end portion is stretched out the adjustment arm housing, worm screw circumferentially is fixed in and regulates on the bolt, is provided with one between adjusting bolt and the adjustment arm housing and relies on surface friction drag to prevent to regulate bolt with respect to adjusting the positioning device that arm housing rotates.Its deficiency: the one, because the design of seal ring is unreasonable, though have sealing, dust-tight function, but the adjusting bolt that is complementary with it does not have the flexible automatically function of adjusting, and can't guarantee the dynamic fit between the worm and wheel, directly the adjustment effect of the whole arm of tone.
The model utility content
Purpose of design: avoid the deficiency in the background technique, design a kind ofly can carry out fast vehicle brake gap, effectively, the reliable automatic braking-gap regulation arm of adjusting.
Design proposal: in order to realize the foregoing invention purpose.The utility model is adjusted the design of the upper and lower end parts extension spring of axle on structural design, be major technique feature of the present utility model.The purpose of doing like this is: it both can guarantee the positive engagement of worm set and worm gear, can guarantee good fit between gear and the push rod again, thereby reached reliable, the convenient purpose of adjusting vehicle brake gap.
Technological scheme: automatic braking-gap regulation arm, it comprises hand regulation arm, the adjustment axle of adjusting the arm shell in the described hand regulation arm is positioned at adjusts axis hole, the screw rod cover is enclosed within the adjustment axle and goes up and mesh with worm gear, the bottom of adjusting axle is connected with base by small extension spring, geared sleeve is being adjusted axle top and is being cooperated with push rod, and big extension spring is enclosed within the non-toothed part between screw rod cover and gear.
The utility model is compared with background technique, and the one, both guaranteed that hand regulation arm was efficient, stable, worked reliably, laborsaving again, convenient again the adjusting.
Description of drawings
Fig. 1 is the structural representation of automatic braking-gap regulation arm.
Embodiment
Embodiment 1: with reference to attached Fig. 1 and 2.Automatic braking-gap regulation arm, it comprises hand regulation arm, the adjustment axle 4 of adjusting arm shell 1 in the described hand regulation arm is positioned at adjusts axis hole, screw rod cover 3 is enclosed within to adjust on the axle 4 and with worm gear 2 and meshes, the bottom of adjusting axle 4 is connected with base 12 by small extension spring 11, gear 8 is enclosed within to be adjusted axle 4 tops and cooperates with push rod, and big extension spring 9 is enclosed within screw rod and overlaps 3 and the non-toothed part of 8 of gears.
Described worm set 3 constitutes overall structure by cover tooth and sleeve.Described gear 8 constitutes overall structure by gear teeth portion and wheel cover portion.
What need understand is: though the foregoing description is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to restriction of the present utility model; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
