Description
Technical Field
The utility model relates to the technical field of automobile auxiliary braking, in particular to an automobile driver off-seat braking auxiliary system.
Background
At present, a heavy automobile at home and abroad mainly adopts air pressure type braking, wherein the parking braking is air-break braking, a parking loop system of the heavy automobile consists of an air storage cylinder, a connecting pipeline, a parking manual valve, a relay valve and a spring brake cylinder, the air storage cylinder is a pressure container for storing a high-pressure body, the parking manual valve is a switch for manually controlling an on-off air path, the relay valve is an air path switch controlled by an external signal air source to be on and off, a connecting air pipe is used for conducting high-pressure air between the valves, and the working principle is as follows:
when a driver pulls the parking manual valve handle to a parking position, the parking manual valve handle is in a closed state at the moment, compressed air in the air storage cylinder is blocked when the parking manual valve handle is pulled to the parking position through a pipeline, the relay valve has no signal air pressure, the relay valve is closed, high-pressure air in the air storage cylinder is blocked by the relay valve and cannot enter the spring brake cylinder, the spring brake cylinder pushes the push rod out under the action of elastic force to realize braking, when the driver pulls the parking manual valve handle to a driving position, the parking manual valve handle is in a passage state at the moment, the compressed air in the air storage cylinder is supplied to a signal air source of the relay valve through the parking manual valve, the relay valve is opened, the compressed air in the air storage cylinder is directly supplied to the spring brake cylinder through the relay valve, the compression spring and the push rod retract to release the braking, however, the existing braking system has the following three problems.
Firstly, along with the continuous use and the gradual increase of the vehicle age of the vehicle, the abrasion of each part is inevitably brought, in particular, the frequent action of a parking brake handle between 'driving' and 'parking' causes the bayonet at the 'parking' position of a parking manual valve to be abraded, the parking brake handle is bounced from the 'parking' position to the 'driving' position under the action of spring force in the parking manual valve, a driver uses the 'parking' brake to park for a long time or leave the vehicle for a short time, the handle is bounced from the 'parking' position to the 'driving' position due to mechanical abrasion or human error, the brake is released, the vehicle slides under the unmanned control, and traffic accidents are easily caused.
Second, the dangerous accident can be caused by the accident that the driver or the child touches the brake handle.
And thirdly, under the normal running state of the vehicle, the parking brake handle is positioned at the 'running' position, if a traffic accident occurs during running, after the vehicle is impacted violently, if the vehicle rolls over or the vehicle rolls over, the driver is thrown away from the seat, is unconscious or dead, and cannot make the action of pulling the parking brake, and the vehicle can slide under the conditions of no operation and no brake, so that a secondary accident or expanded accident loss is caused.
