Description

Anti-drag-grinding dustproof automobile inclined guide block

Technical Field

The utility model relates to an automobile brake part field especially relates to a prevent dragging and grinding dirt-proof oblique guide block of car.

Background

The reliability of the automobile brake system is an important factor for determining the safe driving of the automobile, because more and more automobiles are arranged on the road at present, the braking is frequent in the driving process of the automobile, the brake needs to work frequently, the brake comprises a cam shaft, a cam, a brake shoe assembly, a brake drum, a friction plate and an inclined guide block used for adjusting the gap between the brake drum and the friction plate, a chute used for allowing the cam shaft to pass through is formed in the inclined guide block, because the cam shaft moves frequently in the chute, some dust is easily caused to cause dust accumulation and blockage on the inner wall of the chute, the friction force between the inner wall of the chute and the cam shaft is increased, the dragging and grinding phenomenon easily occurs in the braking process, the abrasion to the inclined guide block is serious, the braking fault.

Disclosure of Invention

In order to solve the problem, the utility model provides a can prevent to appear the deposition in the spout of guide block to one side, reduce to one side the frictional force between guide block and the camshaft prevent dragging and grind dirt-proof car guide block to one side.

The technical scheme of the utility model: the utility model provides a prevent dragging and grinding dirt-proof car guide block to one side, includes guide block body to one side and sets up the spout on guide block body to one side, be equipped with the lug on the spout inner wall, the lug is convex, the quantity of lug is two, and two lugs symmetry set up, distance between the summit of two lugs and the big or small looks adaptation of diameter of automobile camshaft.

Adopt above-mentioned technical scheme, because be equipped with the lug on the spout inner wall, the lug is convex, and the distance between the summit of two lugs and the big or small looks adaptation of diameter of automobile camshaft, can reduce the frictional force between spout inner wall and the automobile camshaft like this, prevent to drag the mill phenomenon, in addition, the convex setting of lug makes the dust be difficult to at lug surface adhesion, prevents the deposition phenomenon, has prolonged the life of oblique guide block greatly.

The utility model discloses a further setting: the inside fretwork of lug, the lug is equipped with the through-hole of a plurality of evenly distributed on the lug surface, be equipped with dustproof brush in the lug, dustproof brush includes a plurality of evenly distributed in the brush of lug, the diameter size of brush and the diameter size looks adaptation of through-hole, the brush passes the through-hole and exposes the lug surface.

Adopt above-mentioned technical scheme, because the lug is equipped with the through-hole of a plurality of evenly distributed on the lug surface, be equipped with dustproof brush in the lug, the brush on the dustproof brush passes the through-hole and exposes the lug surface, and when the camshaft got into the spout in, the dust that the camshaft surface brought received the frictional force of brush can be cleared up, prevents that the deposition from appearing in the spout inner wall, improves the life of oblique guide block greatly.

The utility model discloses a further setting: the length of the brush exposed out of the surface of the convex block is 5 mm.

Adopt above-mentioned technical scheme, because the length that the brush exposes the lug surface is 5 millimeters, can guarantee when can clear up the dust that the camshaft surface brought, do not influence the camshaft and slide in the spout, avoid appearing the dead phenomenon of card, prevent brake failure.

The utility model discloses a further setting: a reinforcing rod is arranged between the bottom of the convex block and the top point of the convex block, a groove is formed in the contact end of the reinforcing rod and the surface of the convex block, and a lubricant is arranged in the groove.

Adopt above-mentioned technical scheme, because be equipped with the stiffener between lug bottom to the lug summit, can strengthen the intensity of lug, avoid the lug to be flattened by the camshaft, in case the lug surface appears the dust and leads to the lug to be by the extruded phenomenon of camshaft, because stiffener and lug surface contact tip are equipped with the recess, and are equipped with emollient in the recess, and emollient receives the extrusion can the adhesion at camshaft and lug on the surface, reduces the frictional force between camshaft and the lug, further improves oblique guide block's the performance of preventing dragging and wearing.

Drawings

Fig. 1 is a cross-sectional view of an anti-scuffing and dustproof automobile inclined guide block according to an embodiment of the present invention.

Detailed Description

As shown in fig. 1, a dustproof car of preventing dragging and grinding leads piece to one side, including leading piece body 1 to one side and setting up spout 2 on leading piece body 1 to one side, be equipped with lug 3 on the 2 inner walls of spout, lug 3 is arc, the quantity of lug 3 is two, and two lugs 3 symmetry set up, and the distance between the summit of two lugs 3 and the diameter size looks adaptation of car camshaft.

Because be equipped with lug 3 on 2 inner walls of spout, lug 3 is arc, and the distance between the summit of two lugs 3 and the big or small looks adaptation of diameter of automobile camshaft, can reduce the frictional force between 2 inner walls of spout and the automobile camshaft like this, prevent to drag the mill phenomenon, in addition, the convex setting of lug 3 makes the dust be difficult to at 3 surperficial adhesions of lug, prevents to appear the deposition phenomenon, has prolonged the life of oblique guide block greatly.

The inside fretwork of lug 3, lug 3 is equipped with the through-hole 4 of a plurality of evenly distributed on lug 3 surface, be equipped with dustproof brush 5 in the lug 3, dustproof brush 5 includes a plurality of evenly distributed in the brush 6 of lug 3, the diameter size of brush 6 and the diameter size looks adaptation of through-hole 4, brush 6 passes through-hole 4 and exposes lug 3 surface.

Because lug 3 is equipped with a plurality of evenly distributed in the through-hole 4 on lug 3 surface, is equipped with dustproof brush 5 in the lug 3, and brush 6 on the dustproof brush 5 passes through-hole 4 and exposes lug 3 surface, and when the camshaft got into in the spout 2, the dust that the camshaft surface brought received the frictional force of brush 6 and can be cleared up, prevented that the deposition from appearing in 2 inner walls of spout, improved the life of oblique guide block greatly.

The length of the brush 6 exposed out of the surface of the convex block 3 is 5 mm.

Because the length that brush 6 exposes 3 surfaces of lug is 5 millimeters, can guarantee when can clear up the dust that the camshaft surface brought, do not influence the camshaft and slide in spout 2, avoid appearing the dead phenomenon of card, prevent the braking trouble.

A reinforcing rod 7 is arranged between the bottom of the convex block 3 and the top point of the convex block 3, a groove 8 is arranged at the contact end of the reinforcing rod 7 and the surface of the convex block 3, and a lubricant 9 is arranged in the groove 8.

Because be equipped with stiffener 7 between 3 summits of lug 3 bottom to lug, can strengthen the intensity of lug 3, avoid lug 3 to be flattened by the camshaft, in case the lug 3 surface appears the dust and leads to lug 3 to be by the extruded phenomenon of camshaft, because stiffener 7 is equipped with recess 8 with 3 surface contact end of lug, and be equipped with emollient 9 in the recess 8, emollient 9 receives the extrusion can the adhesion at camshaft and lug 3 on the surface, reduce the frictional force between camshaft and lug 3, further improve oblique guide block's anti-drag wear performance.
