Abstract
The invention relates to a drum brake with a low-noise mode. The drum brake comprises a magnetic device, brake arms, brake scotches, a regulating screw and a spring, wherein the brake arms are connected to left and right operation ends of the magnetic device through a guiding axle and a brake spring; the brake scotches are connected to the inner sides of the brake arms though a pin shaft in a swing mode; the regulating screw penetrates through the brake arms and directly reaches the inner sides of the brake scotches; and the spring is arranged between the brake scotches and the brake arms. The drum brake is characterized in that an anti-vibration pad is sleeved at the outer side end of the spring, and the outer side end of the anti-vibration pad leans against the outer side surfaces of the brake scotches. Compared with the prior art, the drum brake provided by the invention has the advantages of low operation noise, is easy to manufacture, and is simple to install.
Description
Technical field
The present invention designs a kind of drum brake.
Background technique
Existing drum brake structure is as shown in Figure 1; Brake shoe 7 is installed on the brake arm 2 through bearing pin 6; There is a spring 5 between brake shoe 7 and the brake arm 2; Fitting area between brake shoe 7 and the Brake drum is regulated through rotating following bolt 10, and the effect of this spring 5 is fitting areas that fitted bolt 10 is adjusted brake shoe 7 and Brake drum.Because processing and installation are Spielpassung between bearing pin, brake arm and the brake shoe, when the break long-play will bring following problem: 1 bump at break work schedule swing arm and bearing pin can strengthen the operation noise of break; 2 can strengthen the operation noise of break at moving watt of the break work schedule and the bump of bearing pin; 3 because break moves for a long time, and the gap between brake arm, bearing pin, the brake shoe can become greatly, thereby makes noise bigger.To the problems referred to above, through reducing the gap between brake arm, bearing pin and the brake shoe, such design can improve the operating noise of break, but has increased processing and installation difficulty.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of operating noise low, and the drum brake of simple low noise mode is installed in processing easily.
The present invention realizes like this; Comprise the magnetic force device, through the axis of guide 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 in the inboard adjusting screw of the through brake shoe on the brake arm, be arranged on the spring between brake shoe and brake arm; Its specialization is to be socketed with damping pad at the outboard end of spring, and the outboard end of damping pad leans against the outer side surface of brake shoe.Brake shoe is connected with brake arm through bearing pin; There are a spring and damping pad between them; Damping pad is enclosed within and is installed in the position that original spring is installed on the spring; The fitting area of brake shoe and Brake drum is regulated through rotating following bolt, and the effect of damping pad and spring is the faying surface that fitted bolt is adjusted brake shoe and Brake drum.Spring just plays the effect of regulating brake shoe and Brake drum fitting area; Can not play the effect of noise reduction sound and vibration damping; And damping pad can not only play the effect of regulating brake shoe and Brake drum fitting area, can play again and reduce the effect that bump produces noise and vibration between brake arm, bearing pin and the brake shoe.When break is opened in the power supply of magnetic force device; Thrust on the magnetic force device is delivered to brake arm earlier at this moment; Brake arm just can pass on the brake shoe through bearing pin afterwards; In the middle of the power transmittance process, the noise that bump produces between brake arm, bearing pin, the brake shoe is eliminated by damping pad with vibration, has improved the operational effect of break greatly.When the break brake application; Power on the spring is delivered to earlier on the brake arm, and brake arm passes through the bearing pin special delivery on the brake shoe, in the middle of the power transmittance process; The noise that bump produces between brake arm, bearing pin, the brake shoe is eliminated by damping pad with vibration, has improved the operational effect of break greatly.
The present invention compared with present technology, it is low to have an operating noise, simple advantage is installed in processing easily.
Description of drawings:
Fig. 1 is the structural representation of prior art;
Fig. 2 is a structural representation of the present invention.
Embodiment:
Combine accompanying drawing and embodiment that the present invention is done describes in further detail at present:
As shown in the figure; The present invention includes the magnetic force device 3 that has the spanner 8 that declutches, through the axis of guide 11 and brake spring 1 be connected magnetic force device about 3 two working ends brake arm 2, be connected the inboard adjusting screw 10 of the inboard brake shoe 7 of brake arm 2, the cross-under through brake shoe 7 on brake arm 2, be arranged on the spring 5 of 2 of brake shoe 7 and brake arms through bearing pin 6 swings; Brake arm 2 is provided with sensitive switch 9; Its specialization is to be socketed with damping pad 4 at the outboard end of spring 5, and the outboard end of damping pad 4 leans against the outer side surface of brake shoe 7.
Claims (1)
