Abstract
A low-noise drum-type brake comprises a magnetic device, a brake arm, a brake scotch, an adjusting bolt and a spring, wherein the brake arm is connected with the left working end and the right working end of the magnetic device through a guide screw rod and a brake spring, the brake scotch is connected with an inner side of the brake arm through a pin roll in a swinging mode, the adjusting bolt is connected with an outer side of a swinging end of a direct brake-shoe in a penetrating mode, the direct brake-shoe is arranged on the brake arm, and the spring is arranged between the outer side of the other swinging end of the brake scotch and the brake arm. The low-noise drum-type brake is characterized in that an end of the outer side of the swinging end of the direct brake-shoe of the adjusting bolt is connected with a damping mat in a sleeved mode, and an outside end of the damping mat leans against the outside end of the brake-shoe. Compared with the prior art, the low-noise drum-type brake has the advantages of being low in work noise and easy to process and manufacture.
Description
Technical field
The utility model relates to 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 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, and the outboard end of beam leans against the outer side surface of brake block.Brake block is connected with brake arm 1 through bearing pin, between brake block and brake arm, has spring, and the effect of spring is that the fit adjustment bolt is adjusted the fitting area between brake block and the Brake drum, plays the effect that reduces vibration and noise simultaneously again.In the outside of brake block and regulate between the bolt and have beam, beam is the fitting area between adjustment brake block and the Brake drum with the effect of regulating bolt, and beam can play again to reduce and vibrate and the effect of noise simultaneously.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 1 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 1 is delivered on the brake block through bearing pin; Vibration and noise that brake block strikes the Brake drum generation weaken reduction by spring and beam, have improved the operational effect of break simultaneously 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.
Description of drawings
Fig. 1 is the structural representation of prior art;
Fig. 2 is the structural representation of the utility model;
The partial enlarged drawing that Fig. 3 is ordered for Fig. 2 A.
Sequence number explanation among the figure: brake arm 1, magnetic force device 2, the handle 3 that declutches, base 4, sensitive switch 5, guide spiro rod 6, brake spring 7, spring 8, brake block 9, bearing pin 10, adjusting bolt 11, beam 12.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
A kind of low noise drum brake structure of the utility model is as shown in Figure 2; Mainly 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, be connected brake arm 1 inboard brake block 9, the outside that is arranged on brake block 9 another swinging ends and the spring 8 between the brake arm 1, cross-under at the brake arm 1 wherein adjusting bolt 11 in the outside of a swinging end of brake block 9 that goes directly through bearing pin 10 swings; 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 12, and the outboard end of beam 12 leans against the outer side surface of brake block 9.。
Claims (1)
