Embodiment Construction

[0027] Such as Figure 1-4 As shown, the double-collar shoe brakes currently on the market do not use a gap self-adjusting mechanism.

[0028] Such as Figure 5-12 As shown, a self-adjusting mechanism for an automobile double-collar shoe brake disclosed by the present invention is installed on a piston 6 and a wheel cylinder block 5 connected to the piston 6, and includes a gap pick 1, a ratchet 7 and a tension spring 3. The gap plectrum 1 is installed on the piston 6 through the positioning bolt 4, the gap plectrum 1 is engaged with the ratchet 7, the other end of the gap plectrum 1 is connected with the tension spring 3 connected to the gap support plate 2, the gap The support plate 2 is fixed on the piston 6 ; the ratchet 7 is fixed on the adjusting bush 8 , and the adjusting bush 8 is installed in the wheel cylinder body 5 .

[0029] In addition, an adjustment screw 10 is also provided, which is connected with the adjustment bush 8, and then the ratchet 7 is fixed; the r...

Abstract

The invention relates to a self-adjusting mechanism of a two leading shoe brake of an automobile, which is installed on a piston and the cylinder body of a wheel cylinder, which is connected with the piston, and the self-adjusting mechanism comprises a clearance poking strip, a ratchet wheel and a back-moving spring; the clearance poking strip is installed on the piston by a positioning bolt, and the clearance poking strip is in clamping connection with the ratchet wheel; the other end of the clearance poking strip is connected with the back-moving spring which is connected at a clearance supporting plate, and the clearance supporting plate is fixed on the piston; the ratchet wheel is fixed on an adjusting bush which is installed in the cylinder body of the wheel cylinder. After related parts are replaced and installed on an original brake wheel cylinder, high oil pressure in the wheel cylinder pushes the piston to move outwards when the brake wheel cylinder is supplied with oil by a master pump, and the piston can drive the clearance supporting plate to move outwards at the same time; meanwhile, outward force is exerted on the back-moving spring, thereby pulling the clearance poking strip, and the clearance poking strip uses the positioning bolt as a fulcrum to poke the ratchet wheel so that the ratchet wheel rotates together with the adjusting bush; an adjusting screw is adjusted outwards by a screw thread, thereby achieving the effect of compensating the clearance between a brake shoe and a brake drum.

Description

technical field [0001] The invention relates to a self-adjusting mechanism of an automobile brake, in particular to a self-adjusting mechanism of a double-collar hoof automobile brake. Background technique [0002] Car brakes often need to be adjusted after the gap between the friction plate and the brake drum increases after the friction plate is worn for a period of time. After adjustment, the brake can work normally. [0003] However, due to factors such as road conditions and usage habits, the wear of the brakes varies. When the time or mileage required in the manual has not been reached, the friction lining has been severely worn, and the user is still unaware that the traditional double collar brake does not have an automatic adjustment mechanism. Moreover, its original design did not install an independent gap automatic adjustment mechanism on this type of brake. Under this background, the double collar shoe brake self-adjusting mechanism was developed. When the fric...
