Description
Technical field:
The utility model relates to a kind of electric Associated brake pedal gear.
Background technology:
Traditional hybrid electric vehicle brake pedal is main or take gas stops as main, and electricity is stopped in car brakeing process ratio seldom.The lock torque that at present electricity is stopped is that program inside sets in advance, is that chaufeur touches to a signal switch while gently stepping on brake pedal, and control system carries out the electricity function of stopping.The degree of whole braking procedure electric braking is constant, and pedal stroke increase process is the process that the gas braking increases.
Traditional brake pedal also has a kind ofly steps on displacement by pedal, control system gathers pedal and steps on the size that the size of displacement decides the moment of electric braking, surpass certain value once pedal stroke, gas is stopped and is also participated in the car load braking, to improve lock torque, this scheme also can increase the braking energy recovery to a certain extent theoretically.
The shortcoming of existing above-mentioned technology.
1, for traditional the first scheme, for ride comfort and the traveling comfort that makes the car brakeing process, this big or small uncontrollable electricity moment of stopping should not be set excessively, and the energy that has caused braking procedure to be reclaimed by electric braking is lower.
2, for traditional first scheme, because control loop needs through processes such as " gather-analyze-provide signal ", often from the chaufeur wish, brake the moment that actual vehicle is braked and there is hysteresis quality, like this driver safety steering vehicle is existed to hidden danger.And this brake mode that gathers pedal position signal by control system, if system in case of system halt, collapse, so just can't gather or provide electric braking moment, this will have a strong impact on the safety of Vehicle Driving Cycle.
Summary of the invention:
The purpose of this utility model is to provide a kind of electric Associated brake pedal gear, and this electric Associated brake pedal gear is simple in structure, easy to use, is conducive to realize the reliability of braking.
The utility model is achieved through the following technical solutions:
The electric Associated brake pedal gear of the utility model, it is characterized in that: comprise stretcher and pedal base, described pedal base is provided with two groups of the first air valve and second air valves side by side, the push rod of described the first air valve directly links with stretcher, the push rod of described the second air valve is located in a Piston bowl jointly with the spring that is arranged at its rear end, described Piston bowl is provided with and the pipeline of braking fuel tank and being communicated with, be serially connected with electromagnetic valve on this pipeline, described piston bush is located in the cylinder cavity, the rear end that is positioned at piston in described cylinder cavity is communicated with the first freeing pipe of the first air valve, first of described the first air valve, two air inlet pipes are communicated with the car load gas tank, described car load gas tank also is communicated with two admission ports of the second air valve, two outlet pipes of described the second air valve lead to brake wheel.
Above-mentioned electromagnetic valve is the 2/2-way electromagnetic valve.
The second freeing pipe of above-mentioned the first air valve is connected with the electric braking device, to trigger electric braking.
The advantage of the electric Associated brake pedal gear of the utility model:
1, realized that electric braking moment can be with the braking intention rapid reaction of chaufeur;
2,, due to all mechanical-hydraulic control, safety, reliability improve;
3, realized the continuity of the gentle braking of electric braking.
The accompanying drawing explanation:
Fig. 1 is organigram of the present utility model.
The specific embodiment:
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below:
The electric Associated brake pedal gear of the utility model, comprise stretcher 1 and pedal base 2, described pedal base 2 is provided with two groups of the first air valve 3 and second air valves 4 side by side, the push rod 5 of described the first air valve directly links with stretcher 1, the push rod 6 of described the second air valve is located in a Piston bowl 8 jointly with the spring 7 that is arranged at its rear end, described Piston bowl 8 is provided with and the pipeline 9 of braking fuel tank and being communicated with, be serially connected with electromagnetic valve 10 on this pipeline 9, described piston bush is located in cylinder cavity 11, the rear end that is positioned at piston in described cylinder cavity is communicated with the first freeing pipe 301 of the first air valve, first of described the first air valve, two air inlet pipes 302 are communicated with car load gas tank 12, described car load gas tank 12 also is communicated with two admission ports 401 of the second air valve, two outlet pipes 402 of described the second air valve lead to brake wheel.
For reasonable in design, above-mentioned electromagnetic valve is the 2/2-way electromagnetic valve.
In order to realize electronic control preferably, the second freeing pipe 303 of above-mentioned the first air valve is connected with the electric braking device, to trigger electric braking.
The utility model principle of work:
When pedal 1 steps down, pedal 1 promotes push rod 5 and the first air valve 3, starts to trigger the electric braking device by the second freeing pipe 303 of the first air valve, realizes electric braking.
So, in the last stage of braking, the first freeing pipe 301 of the first air valve 3 lead to cylinder cavity 11 interior in, guarantee that spring force is less than the elastic force of the second air valve 4 interior pull back springs, and electromagnetic valve 10 is in connected state, Piston bowl 8 does not form airtight cavity, and hydraulic oil wherein stays oil sump tank by electromagnetic valve, and this stage second air valve 4 can not be pushed.
The braking after-stage, spring 7 is fully compressed, utilizes the rigidity characteristics of Compress Spring 7, if continue, strengthens pedal stroke, can promote the second air valve 4, starts the gas braking, and this process electric braking still exists.
If in the last stage of braking, spring 7 is not fully compressed, but the electric braking device is by braking (judging by tachogen) fully, continue to strengthen braking force and can't realize larger electric braking moment, so by the action of electromagnetic valve, be switched to the off-state of electromagnetic valve, even the fluid chamber that Piston bowl 8 forms is transformed into airtight cavity.So, utilize the incompressible principle of liquid, the pressure in intensifying cylinder cavity 11, inferior air pressure can directly promote the push rod 6 of the second air valve, and outlet pipe 402 pipelines of the second air valve 4 are opened, and starts to brake front and back wheel.
The advantage of the electric Associated brake pedal gear of the utility model:
1, realized that electric braking moment can be with the braking intention rapid reaction of chaufeur;
2,, due to all mechanical-hydraulic control, safety, reliability improve;
3, realized the continuity of the gentle braking of electric braking.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
