Brief description of the drawings
By embodiment shown in the drawings, the present invention is described in detail below.Two accompanying drawings illustrate the scheme circuit of the hydraulic pressure of two foundation automobile braking devices of the present invention.
Detailed description of the invention
Shown in Fig. 1, there is series connection main brake cylinder 2 according to the automobile braking device 1 of hydraulic pressure of the present invention, the in the situation that of connecting brake regulation system 3 in centre on this series connection main brake cylinder, connecting the wheel braking cylinder of car side brake 4.Brake equipment 3 is anti-lock and slide control unit of a kind of own known features, for example, can use the applicant's ESP8.0 system.Brake regulation system 3 has Hydraulic Pump 5 and has brake-pressure formation valve 6 and brake-pressure reduction valve 7 for the independent brake-pressure of the wheel of each car side brake 4 regulates in each brake circuit.Hydraulic Pump 5 is driven by a shared electrical motor 8.Such brake regulation system and function thereof are that itself is known and here without detailed introduction.
Car side brake 4 reinforcement voluntarily, that is to say, they have step-up system voluntarily.The step-up system voluntarily of such machinery or hydraulic pressure is known and therefore here without repeating.The reinforcement voluntarily of car side brake 4 represents by the letter " SE " of representative " Se1f-Enerizing " in the drawings.
For operation automobile braking device 1, depress brake pedal 9 and handle thus main brake cylinder 2.Open seperating vale 13 and close simulator valve 23.By opening seperating vale 13, without pressure connect the pressure chamber 12 of main brake cylinder 2 and do not utilize main brake cylinder 2 mineralization pressures.Elementary for this reason or second pressure chamber 12,16 without pressure connect that it doesn't matter.Braking force forms and utilizes Hydraulic Pump 5 to carry out, and the adjusting wheel of the wheel brake pressure in the wheel braking cylinder of car side brake 4 utilizes individually brake-pressure to form valve 6 and brake-pressure reduction valve 7 carries out.Utilize the rated value of the height of wheel brake pressure in the braking force of the pressure initiation car side brake in the pedal stroke simulator 22 that pressure sensor 24 measures or wheel braking cylinder.The power sensor 10 of measurement treadle effort and pedal stroke and/or stroke sensor 11 provide the rated value of redundancy.Braking is a kind of outer force braking, and wherein, Hydraulic Pump 5 forms the pressure source of external energy feedway.Also can be power brake, method be formed the brake-pressure in main brake cylinder 2 pressure chambers 12,16 and utilized Hydraulic Pump 5 to improve pressure by the part of seperating vale 13 or modulated opening.In this regard, this is the braking force reinforcement that a kind of pressure source as external energy feedway has the hydraulic pressure of Hydraulic Pump 5 equally.For this situation, seperating vale 13 preferably forms as apportioning valve.
During by operation main brake cylinder 2, close simulator valve 23, surround the braking liquid volume that pedal stroke simulator 22 contains.Emulator piston 19 is worked with respect to annular piston 20, and this annular piston utilizes simulator spring 21 to be bearing in main brake cylinder 2.In this manner, on brake pedal 9, produce desired treadle effort.
When malfunctioning, carry out auxiliary braking by the manpower that utilizes brake pedal 9 to operate main brake cylinder 2 at Hydraulic Pump 5 or brake regulation system 3.In this case, seperating vale 13 keeps cutting out, thereby brake-pressure formation is undertaken by manual operation main brake cylinder 2 in a conventional manner.Simulator valve 23 stays open, thereby pedal stroke simulator 22 is without pressure and do not form and can improve the counter pressure of treadle effort.The auxiliary braking being undertaken by manpower in the time that outside Power supply is malfunctioning should not obscured mutually with power brake, and the latter is the braking force reinforcement of the electro-hydraulic in the time that outside Power supply works.The reinforcement voluntarily of car side brake 4 also can be in the time that outside Power supply be malfunctioning auxiliary braking time play a role.
From shown in different, all reinforcements voluntarily of car side brake 4 that needn't be all, also a part of car side brake 4 reinforcement voluntarily only, the most all car side brakes 4 of what a automobile shafts reinforcement or reinforcement voluntarily or not.Also can realize and only there is not the embodiment of the automobile braking device 1 of the car side brake 4 of reinforcement voluntarily.In addition, can realize the brake regulation system 3 of simplification, it does not for example have brake-pressure to form the common (not shown) that regulates of car side brake 4 of valve 6 or one of them automobile shafts.Can realize equally the brake circuit only with a hydraulic pressure of automobile braking device 1 or also can there is the embodiment of plural brake circuit (not shown).In addition, automobile braking device 1 can have the brake circuit that is connected with main brake cylinder 2 and form, wherein, then main brake cylinder 2 forms as single loop main brake cylinder, and other brake circuit is directly connected with braking liquid tank 14 external energy also only producing by the Hydraulic Pump 5 by as pressure source as outer force braking loop and handles.
