Abstract
The invention discloses an improved structure of a low-noise drum type brake. The improved structure comprises a magnetic device, brake arms, brake shoes, adjusting bolts and springs, wherein the brake arms are connected to the left work end and the right work end of the magnetic device through guiding screws and brake springs; the brake shoes are in swinging connection with the inner sides of the brake arms through pin rolls; each adjusting bolt penetrates through and is connected onto each brake arm and is directly communicated to the outer side of one swing end of each brake shoe; and one spring is arranged between the outer side of another swing end of each brake shoe and each brake arm. The improved structure is characterized in that a cylindrical damping cushion is sleeved at the end socket of each spring, which is positioned at each brake arm; a counter bore is machined at the part of each brake arm, which corresponds to the cylindrical damping cushion; and the cylindrical damping cushion is embedded into the counter bore. Compared with the prior art, the improved structure disclosed by the invention has the advantages of low work noise and easy processing and manufacturing.
Description
Technical field
The present invention 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 object of the invention 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 present invention seeks to realize like this: 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 the 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; Its specialization is that the termination point casing that is positioned at the brake arm place of spring is connected to the tubular beam; The corresponding tubular beam of brake arm place is processed with a counterbore, and the tubular beam is inlayed in the counterbore.
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; Bump produces between brake arm, bearing pin and the brake block vibration and noise weaken reduction by spring and 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.
Here, the through brake block of the adjusting bolt wherein termination point casing in the outside of a swinging end is connected to beam, and the outboard end of beam leans against the outer side surface of brake block.Like this, regulate vibration and the noise that bump produces between bolt and the brake block and weaken reduction, thereby further improve the operational effect of break by beam.
Beneficial effect
The present invention compared with present technology, it is low to have an operating noise, is prone to the advantage of manufacturing.
