Description
Technical field
The present invention relates to a kind of brake device for car, carried out the device of emergency braking when particularly in case of emergency a kind of or primary brake system lost efficacy.
Background technology
Usually, brake system of car is the indispensable device that guarantees vehicle safe driving.Existing brake system of car only is equipped with a cover main brake device, does not have standby brake equipment.Vehicle in case of emergency, must be braked by brake system in cruising, to avoid taking place traffic accident, if the main brake device is malfunctioning, then unavoidably will cause traffic accident.
In addition,, generally only consider, just mainly consider, and do not propose to increase the scheme of complemental brake system from aspects such as the structural materials of main brake device and adhesion of tyrves from the wheel aspect in order to improve the brake action of main brake device.
Summary of the invention
The present invention seeks to provides a kind of emergent brake for automobile at the above-mentioned problems in the prior art, when the service braking system of automobile is malfunctioning in travelling, this emergency brake device can in time automatically be brought into play brake action, thereby avoids the traffic accident of losing efficacy and to be caused because of the running brake system effectively.
According to emergent brake for automobile of the present invention, comprise: automatically controlled part, the electromagnetic valve that has emergency brake switch and be electrically connected with emergency brake switch, emergency brake switch is positioned at below the brake pedal, and can when emergency braking, make its connection by the brake pedal operation; Air pressure is supplied with part, has air bottle and is installed in the reducing valve that the air bottle exit is used to regulate braking pressure; Brake actuator has first air cylinder and brake plate, and wherein first air cylinder is installed on the car body with rotary way, and communicates with air bottle by electromagnetic valve; One end of brake plate links to each other with first air cylinder, and the other end links to each other with the active installation division part that brake actuator is resetted, and first air cylinder promotes brake plate and contacts with ground and produce friction brake force during work under gas pressure.
Owing to adopted emergency brake device of the present invention, when running into emergency situation or motor vehicle braking system in the vehicle ' when malfunctioning, connect the emergency brake switch that braking depresses face, electromagnetic valve is opened, high pressure gas operation air cylinder in the air bottle, the piston rod of air cylinder stretches out and drives brake plate with active installation division part compounding practice and contact with ground, thereby generation brake drag effect, make vehicle stop rapidly travelling, therefore the present invention can in case of emergency participate in braking, thus the traffic accident that improves braking effect and avoid effectively being caused because of the inefficacy of running brake system.
Description of drawings
Fig. 1 is the schematic diagram of emergency brake device embodiment of the present invention;
Fig. 2 is the rough package drawing of emergency brake device embodiment of the present invention on car body.
The specific embodiment
Describe the present invention with reference to the accompanying drawings.
At first, the structure and the braking principle of emergency brake device of the present invention described with reference to Fig. 1.
Emergency brake device of the present invention comprises automatically controlled part, brake actuator and air pressure supply unit branch.
Wherein the electric control part branch comprises emergency brake switch 1 that is positioned at below the brake pedal 2 and the electromagnetic valve 6 that is electrically connected with emergency brake switch 1.Emergency brake switch 1 is an operating switch, can make emergency brake device response emergency situation and start air pressure to supply with part, thereby pushing executing mechanism carries out emergency braking.Emergency brake switch 1 can be selected BK Brake Switch or travel switch for use.
Brake actuator comprises rocking arm 3, retracing spring 9, brake plate 4, air cylinder 5.Air cylinder 5 is installed on the mount pad that is positioned at car chassis.The piston rod of air cylinder 5 connects an end of brake plate 4 in the pivot joint mode, and the other end of brake plate 4 connects rocking arm 3 in the pivot joint mode, can be hinged by retracing spring 9 and car body chassis by the rocking arm 3 that low carbon steel pipe is made; Perhaps the other end of brake plate 4 links to each other with the piston rod of another air cylinder (not shown) on being installed in the car body chassis in the pivot joint mode.
Main stressed member when air cylinder 5 is emergency brake device of the present invention work, the operation pressure on general wagon should be less than 5MP, and the operation pressure on full size vehicle should be 2-3MPa less than 8MP in the present embodiment.
Air pressure supply unit branch comprises air bottle 8 and pressure reducer 7, and pressure reducer 7 is installed in air bottle 8 exits, is used to regulate the required air pressure of supply air cylinder 5 work.Air bottle 8 is small-sized steel cylinder, and it communicates with air cylinder 5 by electromagnetic valve 6, is the power energy storage of required air pressure when supplying with air cylinder 5 work.The gas storage pressure of air bottle 8 is 16MP, and this capacity can roughly satisfy emergency brake device work three times.In the present embodiment, the pressure of pressure reducer 7 can be set at 2-3MP.
The following describes the braking principle of work of emergency brake device of the present invention.As shown in Figure 1, automobile brake pedal 2 has certain stroke, is used to control brake torque, keeps certain distance between emergency brake switch 1 and the brake pedal 2, and this distance guarantees that when normal brake application, emergency brake switch 1 can not connected.When emergency braking or main brake device are malfunctioning, chaufeur is firmly stepped on brake pedal 2 near the end position of brake pedal by the light of nature, thereby emergency brake switch 1 is connected, electromagnetic valve 6 is opened, high pressure gas in the air bottle 8 enter in the air cylinder 5 after reducing valve 7 decompressions, under the effect of air pressure piston rod are released, and piston rod drives brake plate 4 with rocking arm 3 cooperations and contacts with ground, thereby the generation brake drag effect makes vehicle stop rapidly travelling.
2 general layouts of explanation emergency brake device of the present invention on car body with reference to the accompanying drawings.As shown in Figure 2, emergency brake device of the present invention comprises two groups of actuating units, and before and after being installed between the bridge, the distance along lateral direction of car between two groups of actuating units is slightly less than wheelspan, and the point of attachment of itself and vehicle body is chosen in the chassis crossrail place.
Between two groups of brake actuators shown in Figure 2 about the longitudinal direction of car symmetric arrangement, and the parallel axes of every group of brake actuator is in longitudinal direction of car, in other words, the axis of the axis of rocking arm 3 and air cylinder 5 piston rods is positioned on the plane that is parallel to longitudinal direction of car substantially.One group, three groups brake actuators also can be set in addition.
Make 4 pairs of ground-surface application force sums of two groups of brake plates be no more than 1/2 of car load total amount, strong excessively to prevent secondary braking sytem when work application force, make wheel and ground-surface adhesive ability deficiency, and problems such as appearance sideslip.
