Description

Truck brake drum for accelerating air flow and reducing temperature

Technical Field

The utility model belongs to the technical field of brake drums, and particularly relates to a truck brake drum capable of accelerating air flow and reducing temperature.

Background

At present, most domestic load type trucks use drum brakes, and in long downhill road sections, the brakes work for a long time, so that heat dissipation is not timely, braking failure or braking function is reduced, traffic accidents are caused, economic losses are caused for car owners and society, and casualties are caused under serious conditions.

How to cool the brake drum becomes a necessary solution. On a passenger car, because the driving road surface is flat and clean, holes are usually formed in the brake drum, so that the air enters the brake to cool. However, the road conditions of the truck are generally construction sites, the environment is severe, and the brake drum holes applied to the truck can lead to sundries and muddy water entering the brake drum, so that the service life of the brake system is shortened, and the brake system is obviously unsuitable.

Disclosure of utility model

The utility model aims to solve the technical problems and provide the truck brake drum for accelerating air flow and reducing temperature, so that the aim of reducing the temperature of the brake drum is achieved by changing the angle of the brake drum reinforcing ribs and increasing the flow speed of external air. In order to achieve the above purpose, the technical scheme of the utility model is as follows:

The utility model provides a truck brake drum accelerating air flow cooling, includes the brake drum, be provided with a plurality of strengthening ribs on the outer lane surface of brake drum, a plurality of strengthening ribs equidistance interval sets up, the one end of brake drum is the steel ring installation face, and the another side of brake drum is close to the car central line, the central line of strengthening rib forms 15-20 contained angles with the brake drum axis, the circumference of brake drum is provided with a corresponding line, the outer lane surface setting of strengthening rib protrusion brake drum, the strengthening rib includes by corresponding line be close to car central line orientation setting and with the outer lane surface concentric setting of brake drum first reinforcing part, by corresponding line be close to the second reinforcing part of steel ring installation face orientation setting and follow first reinforcing part slope transition to the outer lane surface of brake drum.

Specifically, the central line of strengthening rib and the axis of brake drum form 15 contained angles.

Specifically, air is introduced into the rib position grooves between adjacent reinforcing ribs, and the air is guided out from the direction of the steel ring mounting surface.

Compared with the prior art, the beneficial effects of accelerating the air flow and cooling of the truck brake drum are mainly shown as follows:

the design direction of the 15-degree angle of the reinforcing rib increases the air flow rate of the entering air along with the running of the vehicle, increases the air quantity flowing in unit time and increases the heat taken away at the same time; the opening direction of the reinforcing ribs is more beneficial to introducing air into the space where the steel ring mounting surface is located, and the air flow can be increased.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely, but is apparent to those skilled in the art in view of the present utility model.

Examples:

Referring to fig. 1-2, the present embodiment is a truck brake drum for accelerating air flow and cooling, including a brake drum 1, a plurality of reinforcing ribs 2 are disposed on the outer ring surface of the brake drum 1, the plurality of reinforcing ribs 2 are disposed at equal intervals, the center line of the reinforcing rib 2 forms an included angle of 15-20 ° with the center axis of the brake drum 1, a corresponding line 3 is disposed in the circumferential direction of the brake drum 1, the reinforcing rib 2 protrudes out of the outer ring surface of the brake drum 1, one end of the brake drum 1 is a rim mounting surface 11, the other surface of the brake drum 1 is close to the center line of the automobile, the reinforcing rib 2 includes a first reinforcing portion 21 disposed in the direction close to the center line of the automobile by the corresponding line 3 and concentric with the outer ring surface of the brake drum 1, and a second reinforcing portion 22 disposed in the direction close to the rim mounting surface 11 by the corresponding line and transiting from the first reinforcing portion 21 to the outer ring surface of the brake drum 1 in an inclined manner.

In this embodiment, the center line of the reinforcing rib 2 forms an included angle of 15 ° with the center line of the brake drum 1. When the brake drum 1 rotates, air is introduced into the rib position grooves 23 between the adjacent reinforcing ribs 2, and the air is guided out from the direction of the rim mounting surface 11.

When the embodiment is applied, the brake drum 1 rotates, the rib position groove 23 with the opening in the oblique angle direction of the reinforcing rib 2 can introduce air, the air is accelerated by the backflow of the reinforcing rib 2, and the air is led out from the surface of the brake drum 1, so that the flowing speed of the air is increased and the entering amount of the air is increased in the whole process. Through software hydrodynamic analysis, the air flow is increased by about 40% compared with the traditional brake drum, and the heat dissipation effect is greatly improved.

In the design direction of the 15-degree angle of the reinforcing rib in the embodiment, the flow speed of the entering air is accelerated along with the running of the vehicle, the air quantity flowing in unit time is increased, and meanwhile, the heat taken away is increased; the opening direction of the reinforcing ribs 2 is more beneficial to introducing air into the space where the steel ring mounting surface 11 is located, so that the air flow rate can be increased.
