Abstract
The utility model relates to an improved structure of a drum brake capable of reducing the noise. The improved structure comprises a magnetic force device, brake arms which are connected at the left working end and the right working end of the magnetic force device through a guide screw rod and a brake spring, brake shoes connected on the inner sides of the brake arms in a swing manner through pin shafts, a regulating bolt which is connected on the brake arms in a penetration mode and directly arrives on the outer side of one of the swing ends of the brake shoes and a spring arranged between the outer side of the other one of the swing ends of the brake shoes and the bake arm, and the improved structure is characterized in that a vibration damping pad is sheathed at the end of the regulating bolt which directly arrives on the outer side of one of the swing ends of the brake shoes, the outer side end of the vibration damping pad leans against the outer side surface of the brake shoe, the shoe vibration damping pad is sheathed at the end of the spring which is positioned in the position of the brake shoe, and the vibration damping pad of the shoe leans against the outer side surface of the brake shoe. Compared with the prior art, the improved structure disclosed by the utility model has the advantages of low working noise and easiness in processing and manufacturing.
Description
Technical field
The utility model designs a kind of low noise drum brake.
Background technique
Existing drum brake structure is as shown in Figure 1; Brake block 9 is installed on the brake arm 1 through bearing pin 10; There is a spring 8 between brake block 9 and the brake arm 1; Fitting area is regulated through rotation adjusting bolt 11 between brake block 9 and the Brake drum, simultaneously the fitting area of spring 8 fit adjustment bolts, 11 adjustment brake blocks 9 and Brake drum.Because manufacturing and assembling are Spielpassung between brake block 9, bearing pin 10 and the brake arm 1, the break long-play will produce following problem: 1, break work schedule swing arm 1 clashes into the operation noise that can strengthen breaks with bearing pin 10; 2, the moving brake shoe 9 of break work schedule clashes into the operation noise that can strengthen breaks with bearing pin 10; 3, break long-play, the gap between brake arm 1, bearing pin 10, the brake block 9 can become big owing to rub, thereby makes break operation noise bigger.To the problems referred to above, through reducing the gap between brake arm 1, bearing pin 10, the brake block 9, can improve the operating noise of break, but can increase processing cost and installation difficulty.
Summary of the invention
The utility model purpose just provides a kind of simple in structure, and cost is low, the improvement structure of the drum brake that operating noise is low.
The utility model purpose be achieved in that comprise the magnetic force device, through guide spiro rod and brake spring be connected two working ends about the magnetic force device brake arm, through bearing pin swing be connected the inboard brake shoe of brake arm, cross-under the through brake block on the brake arm wherein the outside of a swinging end the adjusting bolt, be arranged on the spring between another swinging end outside of brake block and the brake arm; The through brake block that its specialization is the to regulate bolt wherein termination point casing in the outside of a swinging end is connected to beam; The outboard end of beam leans against the outer side surface of brake block; The termination point casing that is positioned at the brake block place of spring is connected to the brake shoe beam, and the brake shoe beam leans against the outer side surface of brake block.
Brake block is connected with brake arm through bearing pin; Between brake block and brake arm, there is spring; The effect of spring is that the fit adjustment bolt is adjusted the fitting area between brake block and the Brake drum, and beam is vibration and the noise that plays generation when brake block contacts with Brake drum when reducing vibration that break opens a sluice gate to produce between brake arm, bearing pin and the brake block and reducing the break brake application simultaneously with noise.When brake arm is opened in the power supply of magnetic force device; Thrust on the magnetic force device preferentially is delivered to brake arm, and brake arm is transmitted on the brake block through bearing pin afterwards, in the power transmittance process; Vibration that bump produces between brake arm, bearing pin and the brake block and noise weaken reduction by spring and beam and brake shoe beam; Same the power of brake spring is delivered to earlier on the brake arm when the break brake application, and brake arm is delivered on the brake block through bearing pin; Vibration and noise that brake block strikes the Brake drum generation weaken reduction by beam, have improved the operational effect of break so greatly.
Beneficial effect
The utility model compared with present technology, it is low to have an operating noise, is prone to the advantage of manufacturing.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Embodiment 1: like Fig. 1,2, shown in 3; A kind of low noise drum brake of the utility model is as shown in Figure 2; Comprise the magnetic force device 2 that has the handle 3 that declutches, connect base 4 between magnetic force device 2 and the support, through guide spiro rod 6 and brake spring 7 be connected magnetic force device about 2 two working ends brake arm 1, be arranged on sensitive switch 5 between magnetic force device 2 and the brake arm 1, through bearing pin 10 swings be connected the inboard brake block 9 of brake arm 1, cross-under the through brake block 9 on the brake arm 1 wherein the outside of a swinging end adjusting bolt 11, be arranged on outside brake block 9 another swinging ends and spring 8 between the brake arm 1; The through brake block 9 that its specialization is the to regulate bolt 11 wherein termination point casing in the outside of a swinging end is connected to beam 13; The outboard end of beam 13 leans against the outer side surface of brake block 9; The termination point casing that is positioned at brake block 9 places of spring 8 is connected to brake shoe beam 15, and brake shoe beam 15 leans against the outer side surface of brake block 9.
Claims (1)
1. improvement structure that can reduce the drum brake of noise; Comprise the magnetic force device, through guide spiro rod and brake spring be connected two working ends about the magnetic force device brake arm, through bearing pin swing be connected the inboard brake shoe of brake arm, cross-under the through brake block on the brake arm wherein the outside of a swinging end the adjusting bolt, be arranged on the spring between another swinging end outside of brake block and the brake arm; The through brake block that it is characterized in that the regulating bolt wherein termination point casing in the outside of a swinging end is connected to beam; The outboard end of beam leans against the outer side surface of brake block; The termination point casing that is positioned at the brake block place of spring is connected to the brake shoe beam, and the brake shoe beam leans against the outer side surface of brake block.
