Problems solved by technology

[0002] The stability of automobile braking requires the introduction of cooling airflow to cool the brake disc during braking. However, when the ordinary brake cooling channel used to introduce cooling airflow is normally open, the wind resistance will increase, which will increase the driving resistance of the car and increase fuel consumption. or power consumption
In the prior art, the above-mentioned technical problems are usually solved by increasing the diameter of the brake disc. However, increasing the diameter of the brake disc will increase the cost of materials, and the problem of braking stability caused by long-term braking cannot be avoided. In order to overcome this shortcoming, It is possible to change the large designated cooling channel into a small channel by optimizing the design, but the driving resistance caused by the cooling channel cannot be completely avoided

Abstract

The invention provides an active cooling channel for an automobile brake disc, which comprises a cooling pipe, an air inlet, a cooling channel and an air outlet, wherein the end part of the cooling pipe is provided with an air outlet; the air blocking valve is arranged at the air outlet, and the air blocking valve is movably connected with the cooling pipe; the driving mechanism is fixedly arranged on the cooling pipe, and the driving mechanism is in driving connection with the air blocking valve; and the controller is in communication connection with the driving mechanism, and the controller is used for controlling operation of the driving mechanism, so that the driving mechanism drives the air blocking valve to close or open the air outlet. According to the active automobile brake disc cooling channel, the controller and the driving mechanism control the air blocking valve to open and close the air outlet of the cooling pipe, and resistance to an automobile caused by the normally-open state of the air outlet is avoided.

Description

Technical field [0001] The present invention relates to the technical field of vehicle brake cooling equipment, specifically, to an active automotive brake disc cooling channel. Background [0002] Automobile braking stability requires the introduction of cooling air flow during braking to cool the brake disc, but the ordinary brake cooling channel used to introduce cooling air flow is always open, which will increase the wind resistance, thereby increasing the driving resistance of the car, increasing fuel consumption or electricity consumption. Prior art usually uses to increase the diameter of the brake disc to solve the above technical problems, however, increasing the diameter of the brake disc will increase the cost of materials, and can not avoid the braking stability problems caused by long-term braking, in order to overcome this shortcoming, can be optimized by design, the large cooling channel can be changed to a small channel, but can not completely avoid the driving r...
