Description
Technical field
The utility model relates to a kind of brake system of car, more particularly, relate to a kind of arm for adjusting automobile brake clearance automatically from the conditioning function driving mechanism.
Background technique
Braking system is the primary assurance of traffic safety, and the arm for automatically regulating clearance of brake in the braking system is to be used for the excess gap of car braking is adjusted automatically.Traditional excess clearance adjustment method is to adopt manual setting, is difficult to keep balance like this between each wheel, can only rely on the driver to feel that braking gap adjusts after excessive again, occurs traffic accident easily.Commercial car both domestic and external has all adopted arm for automatically regulating clearance of brake in order to improve the Safety performance of car load.
Existing commercial car is after installing arm for automatically regulating clearance of brake, and the safety of products performance improves.The critical component of arm for adjusting automobile brake clearance automatically is clutch assembly, and this clutch assembly claims also from the conditioning function driving mechanism or claim automatic regulating and controlling device that the utility model unification is called from the conditioning function driving mechanism.Because from reliability, the joggled strength of conditioning function driving mechanism, the usability that has determined arm for adjusting automobile brake clearance automatically and working life.The HD type arm for adjusting automobile brake clearance automatically that uses both at home and abroad at present; As shown in Figure 1; That adopts is formed by connecting preceding blind nut 1, seal ring 2, thrust-bearing 3, clutch tooth cover 4, clutch spring 5, clutch gear 6, screw rod axle sleeve 7, housing 8, worm screw 9, spring seat 10, pressure spring 11, spring flap 12 from the conditioning function driving mechanism, as shown in Figures 2 and 3.Can drive clutch teeth cover 4 through clutch spring 5 during brake off clutch gear 6 reverse rotation, worm screw 9 is rotated together; Worm screw 9 drives worm gear; The worm-gear driven camshaft rotates, thus the gap adjustment when realizing automobile brake, owing between clutch tooth cover 4 and spiral shell worm screw 9, be to bore tooth to be connected; And the awl tooth of clutch tooth cover 4 and the worm screw 9 awl tooth depths of engagement have only 0.16mm; Cause joggled strength unstable relatively, skidding can occur in use for some time, and the material specification of the clutch spring 5 that between clutch tooth cover 4 and clutch gear 6, is provided with is little; Intensity is low, and while pressure spring 11 also is easy to generate permanent deformation in use for some time and fracture may appear in spring seat 10.Therefore, at present the working life of arm for adjusting automobile brake clearance automatically short, poor reliability, particularly frequently braking is prone to cause the self-regulated error in the mountain area.
The model utility content
The purpose of the utility model be to provide a kind of long service life, good reliability arm for adjusting automobile brake clearance automatically from the conditioning function driving mechanism.
To achieve these goals; Arm for adjusting automobile brake clearance automatically is made up of preceding blind nut, seal ring, shaft block ring, thrust-bearing, clutch gear, rectangle spring, housing, worm screw, return spring and spring flap from the conditioning function driving mechanism in the utility model; Said clutch gear directly is enclosed within on the end of said worm screw; And between said clutch gear and said worm screw sheathed said rectangle spring; Said thrust-bearing and shaft block ring are directly arranged in the end of clutch gear; The step and said thrust-bearing, the shaft block ring that are formed by said worm screw itself position said clutch gear, and said return spring is located at the other end of said worm screw, and between said worm screw the other end end and said spring flap.
Said clutch gear is provided with the annular groove that is used for said rectangle spring one end of build-in at a side.
The other end of said rectangle spring directly is connected on another integrally formed step of said worm screw itself.
Said seal ring is an O-ring seals.
Existing mechanism is changed to tension force and worm screw, clutch gear, the return spring of rectangle spring from the conditioning function driving mechanism in the utility model adjusted control gear in the elastic element of one; Through experiment, adopt the adjustment moment of the arm for adjusting automobile brake clearance automatically of elastic element regulating device, bring up to 80N.m to 160N.m by original 40N.m, reach 1,000,000 times from the conditioning function endurance test.The problem that frequently braking lost efficacy is got rid of fully, has long service life, the characteristics of good reliability.

Embodiment
To combine accompanying drawing that the specific embodiment in the utility model is done further explain below.
Like Fig. 4 and shown in Figure 5, arm for adjusting automobile brake clearance automatically is made up of preceding blind nut 1, seal ring 2, shaft block ring 13, thrust-bearing 3, clutch gear 6, rectangle spring 14, housing 8, worm screw 9, return spring 15, spring flap 12 with elastic element adjustment control gear from the conditioning function driving mechanism in the utility model.Wherein, Clutch gear 6 directly is enclosed within on the end of worm screw 9, and between clutch gear 6 and worm screw 9 sheathed rectangle spring 14, thrust-bearing 3 and shaft block ring 13 are directly arranged in the end of clutch gear 6; Step and thrust-bearing 3,13 pairs of clutch gears 6 of shaft block ring of itself being formed by worm screw 9 position; And blind nut 1 seals with fixing before further utilizing, and between preceding blind nut 1 worm screw 9, by seal ring 2, can be that the O RunddichtringO seals.Return spring 15 is located at the other end of worm screw 9, and between worm screw 9 the other end ends and spring flap 12.Running is opposite with rectangle spring 14 rotation directions clockwise for clutch gear 6 during braking, and rectangle spring 14 does not tighten power, and worm screw 9 makes worm screw 9 fixing can not rotations under return spring 15 coupling mechanism force effects.Brake off can drive tightening of rectangle spring 14 when clutch gear 6 revolution, drive worm screw 9 by means of the compressive force of rectangle spring 14 and rotates together, and worm screw 9 drives worm gears, the worm-gear driven camshaft, thus the gap when realizing automobile brake is adjusted.
Clutch gear 6 is provided with the annular groove 16 that is used for build-in rectangle spring 14 1 ends at a side.The other end of rectangle spring 14 directly is connected on another integrally formed step of worm screw 9 itself.
The cover of the clutch tooth in the conditioning function driving mechanism 4, clutch spring 5, pressure spring 11 and spring seat 10 have now been deducted from the conditioning function driving mechanism in the utility model; One-way rotation by between clutch gear 6, rectangle spring 14 and the worm screw 9 has realized the adjustment in gap; Fix by means of the reverse of return spring 15 simultaneously, thereby avoided existing four component of risk factors that in the conditioning function driving mechanism, exist.
