Abstract
A drum-type brake capable of effectively reducing noises comprises a magnetic device, brake arms, brake shoes, adjusting bolts and springs. The brake arms are respectively connected with a left working end and a right working end of the magnetic device through guiding threaded rods and brake springs. Each brake shoe is connected with an inner side of one brake arm through a pin shaft in an oscillating mode. Each adjusting bolt is connected with one brake arm in a penetrating mode and reaches an outer side of one oscillating end of the brake shoe. The spring is arranged between the other oscillating end of the brake shoe and the brake arm. The drum-type brake capable of effectively reducing the noises is characterized in that an end head of each spring arranged on the brake arm is provided with a drum-shaped cushion pad, a counter bored hole is disposed on the brake arm corresponding to the drum-shaped cushion pad, and the drum-shaped cushion pad is embedded into the counter bored hole. An end head of each adjusting bolt reaching the outer side of one oscillating end of the brake shoe is connected with the cushion pad in a sleeved mode, and an outer side end of the cushion pad is located on an outer side of the brake shoe. Compared with the prior art, the drum-type brake capable of effectively reducing the noises has the advantages of low working noises and easy 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 drum brake that can effectively reduce noise 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; 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; The tubular beam is inlayed in the counterbore; 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.
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.
Beneficial effect
The present invention 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;

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; Its specialization is that the termination point casing that is positioned at brake arm 1 place of spring 8 is connected to tubular beam 12; Brake arm 1 corresponding tubular beam 12 places are processed with a counterbore 14; Tubular beam 12 is inlayed in the counterbore 14; The through brake block 9 of the adjusting bolt 11 wherein termination point casing in the outside of a swinging end is connected to beam 13, and the outboard end of beam 13 leans against the outer side surface of brake block 9.
