Brake device with cooling effect

Technical Field

The utility model belongs to the technical field of brake equipment technique and specifically relates to a brake equipment with cooling effect is related to.

Background

The drum brake is characterized in that a brake transmission mechanism is utilized to enable a brake shoe (brake shoe) to press a brake friction plate (brake sheet) on the inner side of a brake drum (brake pot), so that braking force is generated, wheels are decelerated or stopped within the shortest distance as required, driving safety is guaranteed, and the automobile is reliably parked and cannot automatically slide. The rotating element of the drum brake is a brake pot which is mounted on a hub. The fixed element is a brake shoe on which the brake plate is mounted. When the brake is used for braking for a long time on a long downhill, a brake pad and a brake pot generate a large amount of friction heat by friction, and the temperature of the brake pot rises. Because the brake pot is installed on the wheel hub and is close to the tire, the high-temperature brake pot often causes the accidents of tire burst and vehicle burning, and has great threat to the safety of drivers. The existing cooling method is spray cooling, and a spray head is adopted to spray water for cooling the brake pot, but the method not only easily causes waste of water resources and general cooling effect, but also needs to carry a large water tank, and increases the burden of driving.

Detailed Description

Examples

Fig. 1 is the utility model relates to a brake shoe cross section structure schematic diagram of brake equipment embodiment with cooling effect, fig. 2 is the utility model relates to a structure schematic diagram of brake equipment embodiment with cooling effect, fig. 3 is the utility model relates to a circulative cooling structure schematic diagram of brake equipment embodiment with cooling effect. As shown in fig. 1 to 3, a brake apparatus having a cooling effect includes a brake pot 9, a brake pad 10, and a brake shoe 1, wherein the brake pot 9 is fixed to a hub to rotate with the hub. The brake sheet 10 and the brake shoes 1 are positioned in the brake pot 9, and a brake wheel cylinder 11 and a return spring 12 are arranged between the two brake shoes 1. The brake block 10 is fixed on the inner side wall of the brake pot 9 through the bolt 8, and the brake shoe 1 is fixed on the vehicle body.
