The utility model discloses in, because of constituting the wind channel between adjacent triangle muscle leaf and brake drum face, the flange, so the brake drum can form the air axial in the wind channel and flow when incessantly rotating, avoids forming the local heat island in the engine compartment, has also consequently avoided the brake drum probably to appear the condition of deformation damage under high temperature state.
Description
Technical Field
The utility model belongs to the technical field of auto-parts, a brake drum that forms air axial flow is related to.
Background
Due to the limitation of the overall structure of the armored vehicle, the brake device is usually arranged in a power cabin of the vehicle and is far away from a heat dissipation air duct of the power cabin, the ambient temperature in the power cabin is usually above 70 ℃, when the armored vehicle executes a battle mission or other long-time severe operation missions, the kinetic energy of the vehicle is converted into heat energy due to brake friction, and the air circulation and heat dissipation are poor, so that a local heat island is easy to appear in the power cabin, once the local heat island appears, the temperature of a brake drum is rapidly increased, the friction coefficient of the brake drum is reduced, and the high-temperature failure condition is easy to appear, and under the repeated action of brake force, the brake drum with higher temperature may deform, and the service life of the brake device is.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a: the brake drum can rotate by itself, axial airflow is formed in a certain area, a local heat island is prevented from occurring, and the situation that the brake drum is likely to deform and damage in a high-temperature state is avoided.
The problem that the brake drum is likely to deform and damage in a high-temperature state is solved.
The utility model adopts the technical scheme as follows:
the utility model provides a brake drum that forms air axial flow, includes the flange, and the equipartition has a plurality of triangle muscle leaves on the outer wall of flange, and the flange is through a plurality of triangle muscle leaf fixedly connected with brake drum face, and constitutes the wind channel between adjacent triangle muscle leaf and brake drum face, the flange.
As a preferable mode, the bevel angle between the triangular rib blade and the flange is 5-10 degrees.
Preferably, the brake drum surface coincides with the center of the flange.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
1. the utility model discloses in, because of constituting the wind channel between adjacent triangle muscle leaf and brake drum face, the flange, so the brake drum can form the air axial in the wind channel and flow when incessantly rotating, avoids forming the local heat island in the engine compartment, has also consequently avoided the brake drum probably to appear the condition of deformation damage under high temperature state.
2. The utility model discloses in, because of the oblique angle between triangle muscle leaf and the flange is 5 ~ 10, so can form the axial air current in triangle muscle leaf both sides when the brake drum rotates, play radiating effect to strengthen arresting gear's radiating effect with this, guarantee arresting gear's performance.
3. The utility model discloses in, be three horn shapes because of triangle muscle leaf, so can play the effect that full power supported to the brake drum face to can reduce the risk that brake drum face friction surface warp under the high temperature state, thereby improve the motor-driven factor of safety of vehicle.
