Abstract
The invention relates to a mechanical abrasion instructor of vehicle brake friction linear, wherein it is characterized in that: the abrasion instructor and the brake adjusting arm are mounted at the outer end of cam axle, to match the spline of cam axle, to be axially fixed via flexible baffle ring; the instructor initial mounting range cut, the replace friction linear instruction range cut, and friction linear abrasion limit instruction cut are mounted with the arrow mark aligned with the outer end of cam axle; said abrasion instructor can be any shape. Without detaching the brake drum, the maintainer can watch the rotation degree of instruction mark, to obtain the abrasion condition of friction linear, to replace the linear.
Description
Technical field:
The present invention relates to a kind of mechanical wear indicator for commercial vehicle braking friction lining, in belonging to, the technical field of heavy motor truck air braking system.
Background technique:
The modern Commercial car should have reliable braking system, and concerning the actuator-break of braking system, the Performance Match of its component is even more important, so require also more and more higher to break component performance and effect.In J6 commercial car series braking system development process, for satisfying brake legislation,, the gap automatic adjusting mechanism is housed particularly at the traditional braking device, exist the maintenance man can not accurately observe the abrasion condition of brake lining.
Summary of the invention:
The object of the invention provides a kind of novel mechanical wear indicator for commercial vehicle braking friction lining, wear indicator is according to the rotation lift of the cam of camshaft, cam angle when calculating friction facing and reaching wear limit, wear indicator cause the camshaft degree and corresponding rotation that increase gradually along with the wearing and tearing of friction facing; Do not needing to pull down under the situation of brake drum, the maintenance man can understand the abrasion condition of friction facing exactly by observing the angle that turns over of wear indicator cue mark, is convenient in time change friction facing.
Technological scheme of the present invention is achieved in that mechanical wear indicator for commercial vehicle braking friction lining, it is characterized in that: wear indicator and braking adjusting arm are assemblied in the outer end of camshaft jointly, spline fitted with camshaft, adopt circlip to axially fasten in the outer end of camshaft, the initial fitting limit gap of indicator, replacing friction facing indicating range gap, friction facing wear limit indicating range gap reach the arrow mark installment of aliging with the camshaft outer end on the wear indicator; Wear indicator be any geometrical shape.
The arrow mark installment that good effect of the present invention is the initial fitting limit gap of indicator on the wear indicator, change friction facing indicating range gap, friction facing wear limit indicating range gap and align with the camshaft outer end; Do not needing to pull down under the situation of brake drum, the maintenance man can understand the abrasion condition of friction facing exactly by observing the angle that turns over of wear indicator cue mark, is convenient in time change friction facing; The geometrical shape of brand-new wear indicator is attractive in appearance, the saving material.
Description of drawings:
Fig. 1 is the structural representation of invention;
Fig. 2 is an assembly structure schematic representation of the present invention.
Embodiment:
The present invention will be further described below in conjunction with accompanying drawing: as shown in Figure 1, 2, mechanical wear indicator for commercial vehicle braking friction lining, it is characterized in that: wear indicator 1 and braking adjusting arm 2 are assemblied in the outer end of camshaft 3 jointly, spline fitted with camshaft 3, adopt circlip 4 to axially fasten in the outer end of camshaft 3, and assurance changes the arrow mark of wear indicator and the arrow mark of camshaft 3 outer ends aligns; The initial installation gap of wear indicator 1 and the arrow label alignment of braking adjusting arm 2.Wear indicator 1 is according to the rotation lift of camshaft 3 cams (Archimedes spiral cam or involute cam all can) characteristic, cam angle when calculating friction facing and reaching wear limit, wear indicator 1 cause camshaft 3 corners and corresponding rotation that increase gradually along with the wearing and tearing of friction facing.Wear indicator 1 be any geometrical shape.
Claims (2)
