Shell.
Above several situation service brake failures occur and implement mechanical spring braking, in ordinary circumstance in this case
Under, after operator brake pedal depresses, discovery vehicle can not be braked, and in this case, driver can attempt to implement parking braking,
But there is the reaction time difference in driver, have little time to implement parking braking, can cause serious accident.
Summary of the invention
To solve the above-mentioned problems, it the present invention provides emergency braking system when a kind of vehicle driving brake fade, mentions
It is capable of the emergency braking system of quick start parking braking when for a kind of vehicle driving brake fade.To achieve the above object, originally
Invent the technical solution taken are as follows: emergency braking system when a kind of vehicle driving brake fade, including brake gear, driving system
Dynamic device and holding brake device, the brake gear include brake pedal, service brake pump, emergency stop switch, fixation
Frame and bolt, the fixed mount setting are U-shaped frame, the top of the brake pedal by bolt in a rotatable way with
The top of fixed frame is connected, and the upper end of fixed frame, the emergency braking are arranged in by bolt for the service brake pump
The lower end of fixed frame is arranged in by bolt for switch, and the front of brake pedal is connected with service brake pump by bolt, is used for
Brake pedal controls service brake pump, and service brake pump is connected with service braking device, controls the service brake of vehicle, promptly
Brake switch is connected with holding brake device, controls the parking braking of vehicle.
Further, it is provided with brake lamp on the right side of brake pedal, when brake pedal moves to the left, brake lamp switch
Closure, brake lamp light, and indicate brake behavior.
Further, holding brake device includes that parking solenoid valve, fuel tank, preceding bridge parking decompression spring arrangement and rear axle are stayed
Vehicle decompression spring arrangement, the parking solenoid valve respectively with fuel tank, preceding bridge parking decompression spring arrangement, rear axle parking decompression bullet
Spring device is connected, and controls the oil circuit of fuel tank, and then controls preceding bridge parking decompression spring arrangement and rear axle parking decompression spring dress
It sets, carries out parking braking.
Further, emergency stop switch is set as ladder-like touching switch structure, convenient to cooperate with brake pedal, works as brake
Vehicle pedal step on maximum angle when, brake pedal is contacted with emergency stop switch, and emergency stop switch can timely respond to, and is avoided
Because touching is insensitive to lead to the phenomenon that cannot opening emergency stop switch in time.
Compared with prior art, the invention has the following advantages: depressing brake pedal when operator brake, driving
Brake failure, the pedal that continues to touch on the brake touch emergency stop switch, open parking braking, in time stop vehicle to maximum angle
Only, it avoids because driver has little time to operate and lead to the phenomenon that cannot opening parking braking in time.
Detailed description of the invention
Below in conjunction with attached drawing, the invention will be described in further detail.
