Description
Technical Field
The utility model relates to an atmospheric pressure drum brake inner structure has especially related to an atmospheric pressure drum brake has friction disc of wearing and tearing indicator strip.
Background
The friction plate inside the existing air pressure drum brake is of a structure without a side groove, the friction plate belongs to a quick-wear part, the abrasion condition of the friction plate needs to be checked regularly when a vehicle runs, related parts such as a brake drum need to be detached during checking to observe the condition of the surface abrasion position of the rivet and the friction plate, operation is troublesome, and the abrasion service condition of the friction plate cannot be observed effectively and visually. If the abrasion condition of the friction plate cannot be judged timely and effectively, the abrasion transition of the friction plate may scratch the working surface of the brake drum, abnormal sound occurs, parts are damaged, certain economic loss is caused, meanwhile, the braking efficiency is low, and potential safety hazards are increased.
SUMMERY OF THE UTILITY MODEL
The utility model mainly solves the not enough that exists among the prior art, provides a pneumatic drum brake has friction disc of wearing and tearing instruction area, and the friction disc wearing and tearing condition can effectively be observed in the design of friction disc side groove structure, reminds the driver to change the friction disc, avoids transition wearing and tearing to lead to parts damages such as brake drum, reduces economic loss, reduces the braking inefficacy risk that friction disc wearing and tearing seriously lead to, promotes the security, reduces raw and other materials simultaneously, reduce cost.
The above technical problem of the present invention can be solved by the following technical solutions:
the utility model discloses a both sides of friction disc are opened there is symmetrical arrangement's side recess, and the side recess is arranged on friction disc both sides face, and the side recess is the fan-shaped sunken face that shares limit with the friction disc inner arc of friction disc side.
The two side grooves are symmetrically arranged on two sides of the center line of the friction plate.
The friction plate is connected to the brake shoe through a rivet.
The rivets are arranged on a plurality of positions on the surface of the friction plate, and the heads of the rivets are lower than the outer arcs of the grooves on the side faces.
The highest point of the side groove is higher than the rivet head riveted on the friction plate.
The beneficial effects of the utility model are that:
1. the structure of the utility model can effectively observe the abrasion condition of the friction plate, remind the driver to replace the friction plate, avoid the damage of parts such as the brake drum caused by transitional abrasion, and reduce the economic loss;
2. the structure of the utility model reduces the risk of brake failure caused by serious abrasion of the friction plate, and improves the running safety of the vehicle;
3. the utility model discloses the structural material reduces, reduce cost to a certain extent.

In the figure: 1. friction plate, 2, side recess, 3, rivet head, 4, friction plate inner arc.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 3, two sides of the friction plate 1 are provided with symmetrically arranged side grooves 2, the side grooves 2 are arranged on two sides of the friction plate 1, and the side grooves 2 are fan-shaped sunken surfaces which are coplanar with the inner arc 4 of the friction plate on the side of the friction plate 1.
The two side grooves 2 are symmetrically arranged on two sides of the center line of the friction plate 1. The inner arc of the side groove 2 is shared with the inner arc 4 of the friction plate 1.
The friction plate 1 is connected to the brake shoe through rivets.
As shown in fig. 3, rivets are arranged on the surface of the friction plate 1 at a plurality of positions, and the rivet heads 3 are slightly lower than the outer arcs of the side grooves 2.
The highest point of the side groove 2 is slightly higher than the rivet head 3 riveted on the friction plate 1.
The utility model discloses with two fan-shaped recesses of the friction disc both sides face design originally as shown in fig. 2 on prior art basis, fan-shaped recess inner arc is on the same side with the friction disc inner arc, and the outer arc of fan-shaped recess is a little higher than the rivet head of riveting on the friction disc. Through the utility model discloses as shown in fig. 1 after the design installation of the friction disc both sides face groove structure shown in fig. 3, can effectively observe the friction disc wearing and tearing condition, effectively avoid leading to rivet head and brake drum to cut the friction risk because of transition wearing and tearing, avoid the braking to become invalid simultaneously.
The utility model discloses a concrete implementation process is as shown in FIG. 3, and the fan-shaped groove structure of friction disc both sides face design can effectively observe the friction disc wearing and tearing condition, reminds the driver to change the friction disc, avoids transition wearing and tearing to lead to parts damages such as brake drum, reduces economic loss, reduces the braking inefficacy risk that friction disc wearing and tearing seriously lead to, promotes the security, reduces raw and other materials simultaneously, reduce cost.
