Embodiment 1

[0043] figure 1 , figure 2As shown, the present embodiment provides an air jet auxiliary braking device, including a wheel brake disc 2 , a transmission assembly 3 , an air compression assembly, a clutch 4 , an air injection pipe, and a controller 6 .

[0044] The wheel brake disc 2 is used to generate a braking force that hinders the movement or movement tendency of the vehicle. The wheel 1 of each vehicle is equipped with a wheel brake disc 2, and the wheel brake disc 2 will rotate with the rotation of the wheel. And when braking, the brake disc 2 is clamped by the brake caliper to produce a frictional moment that prevents the rotation of the wheel to achieve braking.

[0045] The transmission assembly 3 is transmission connected to the wheel brake disc 2, and transmits the power of the wheel brake disc 2 to the air compressor 5 through the transmission assembly 3, so that the air compressor 5 performs air compression.

[0046] The air compression assembly includes a conn...

Embodiment 2

[0059] The present embodiment provides an automobile 10 including the above-mentioned jet auxiliary braking device. For the structure of the jet auxiliary braking device, refer to the content in Embodiment 1. The car 10 can spray air in the same direction as the car 10 is traveling to increase the braking effect, or spray air upwards to increase the downward pressure of the car 10 to increase adhesion, thereby assisting the car 10 in braking and making the driving process safer.

Embodiment 3

[0061] This embodiment provides a method for assisting the braking of the automobile 10. The above-mentioned jet auxiliary braking device is applied. For the structure of the jet auxiliary braking device, refer to the content in Embodiment 1, which includes the following steps:

[0062] S1, the controller 6 receives a braking signal related to the brake pedal, wherein the braking signal includes an action of the driver stepping on the brake pedal;

[0063] S2, the controller 6 responds to the brake signal, controls the clutch 4 to close, transmits the power of the transmission assembly to the air compressor 5, and makes the air compressor 5 compress the air and send the compressed air to into the air storage tank 7, and control the opening of the air injection valve 8, and the compressed air is ejected from the air injection hole 9 to assist the braking of the automobile 10.

[0064] Brake at any time, as long as the driver steps on the brake pedal, the controller 6 receives t...

Abstract

The invention provides a jet-type auxiliary brake device and method and an automobile, and relates to the field of brake systems of automobiles. The brake device comprises wheel brake discs, transmission assemblies, an air compression assembly, clutches, jet pipelines and a controller. Each transmission assembly is in transmission connection with the corresponding wheel brake disc, and the air compression assembly comprises air compressors and a gas storage tank which are connected. The clutches are used for cutting off power of the transmission assemblies and transmitting the power of the transmission assemblies to the air compressors. The jet pipelines are arranged between the gas storage tank and jet holes in the surface of the automobile and provided with jet valves. The controller iselectrically connected with the clutches, the air compression assembly and the jet valves separately. The invention further provides the automobile with the auxiliary brake device and the auxiliary brake method. Through the arrangement of the auxiliary brake device of the automobile, when the automobile needs to be braked, jetting can be conducted upwards and / or in the same direction of automobiledriving to increase braking force.

Description

technical field [0001] The invention relates to the field of braking systems of vehicles, in particular to a jet auxiliary braking device, method and automobile. Background technique [0002] The braking system is the main subsystem of the car, which can be used to control the car to stop, decelerate, and maintain a certain speed. It is an important system for driving safety and an essential subsystem of the car. However, the maximum braking force of the car braking system is limited by the adhesion between the car and the ground (the maximum friction between the car and the ground), that is, if the maximum braking force of the car braking system exceeds the adhesion between the car and the ground , the wheels of the car will be locked, causing the car to lose its steering control ability, or appear to flick the tail and turn around, which will bring traffic safety problems. [0003] At present, the patent CN100430255C discloses a motor vehicle jet driving system, which uti...
