Embodiment Construction

[0032] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0033] Such as figure 1 and figure 2 As shown, the flow process of the brake drum spraying method is carried out through the following steps:

[0034] Step S1: After the car is started, it is judged whether the water spray switch is turned on, if yes, go to step S3; if not, go to step S2;

[0035] Step S2: Determine whether the brake switch outputs a high-voltage signal, that is, whether the brake switch is performing service braking. When the vehicle is performing service brake, the brake switch is turned on, and high voltage is output at both ends. If yes, proceed to step S3; if not, end the brake drum water spray cooling;

[0036] Step S3: The brake drum water spray device is turned on, a...

Abstract

The invention provides a brake drum water spraying method. The brake drum water spraying method includes the following steps of judging whether a water spraying switch is turned on when an automobile is started, and starting a brake drum water spraying device to spray water and cool a drake drum according to judgment results; judging whether a brake switch outputs a high voltage signal, and subjecting the brake drum to water spraying and cooling or finishing spraying water and cooling the brake drum according to judgment results; and judging whether voltage output by the brake switch is reduced in a short time, subjecting the brake drum to water spraying and cooling or delaying water spraying time according to judgment results, and finishing spraying water for the brake drum. Besides, the invention further provides a brake drum water spraying auxiliary system which is relatively simple in structure, good in generality, and capable of effectively assisting in a brake drum manual water spraying system, effectively solving the problem that the brake drum is insufficiently cooled, and simultaneously, providing cooling water for the brake drum under the conditions that the brake drum manual water spraying system fails or the water spraying switch is forgotten to be turned on.

Description

technical field [0001] The invention relates to the field of vehicle braking, in particular to a brake drum water spraying method, a brake drum water spray auxiliary system and a vehicle. Background technique [0002] With the continuous development of society, various vehicles have become an indispensable means of transportation in people's lives. However, when the vehicle needs to be braked for a long time, the friction between the brake drum and the brake pad is easy Lead to excessive temperature and damage, bring hidden danger to traffic safety. In order to solve this problem, in the related art, the operator manually opens the water delivery valve switch to water-cool the brake drum, and when the vehicle stops, the water delivery valve switch is closed immediately. [0003] In the related art, the patent application number CN92225621.7 discloses an automatic control cooling water spraying device, including a switch, a coil, an iron core, an armature, a sealed bottom, a...
