Fig. 2 illustrates the hydraulic circuit diagram of the motor vehicles of second embodiment with brakes, and
Fig. 3 illustrates the embodiment slightly revised of the main braking cylinder of Fig. 1 and Fig. 2.
Detailed description of the invention
Fig. 1 illustrates motor vehicles 2 with the form of hydraulic circuit diagram. Front axle (not showing further) provides two front vehicle wheels 4,6. Correspondingly in rear axle (not showing further), it is scheduled that rear wheel 8,10. Motor vehicles 2 can also be referred to as motor vehicle driven by mixed power and have an electrically powered machine (not showing further), this electrically powered machine is operatively connectable on front axle and has an explosive motor (not showing further), and this explosive motor is operatively connectable on hind axle. Driving it should be clear that there is substantial amounts of so-called hybrid power, these all fall within the scope of protection of the present invention.
In this context, the effect of this electrically powered machine operating motor when the wheel 4,6 of front axle is to be driven by this electrically powered machine on the one hand. Additionally, serve as in the recovery stage of electromotor at electrically powered machine, the braking energy of produced two amounts can be converted into electric energy by described electrically powered machine in the braking procedure of these motor vehicles. Energy regenerating in the braking procedure of motor vehicles 2 is also referred to as regeneration. The energy reclaimed in braking procedure can be stored in accumulator or capacitor.
Except the recovery playing braking action, motor vehicles 2 include a brake fluid system 12. In this context, it is provided that the pedal 14 worked on so-called equalizer bar 16. This equalizer bar 16 is for setting between front axle and rear axle and therefore brake pressure distribution between front vehicle wheel 4 and 6 or rear wheel 8 and 10. It is distributed about to the brake pressure of front vehicle wheel 4,6, adjacent first main braking cylinder of equalizer bar 16 and the second main braking cylinder 18,20, on the wheel drag 22,24 that wherein the second main braking cylinder 20 is fluidly connected to be arranged on front vehicle wheel 4,6. The opposition side of equalizer bar 16 adjoins the 3rd main braking cylinder 26, and the 3rd main braking cylinder is fluidly connected on the wheel drag 28,30 of rear wheel 8,10 in known manner. Act on the brake pressure on front vehicle wheel 4,6 and the brake pressure acted on rear wheel 8,10 is monitored by means of sensor 32,34 all in known manner.
As has been described, this electrically powered machine is operatively connected on the front axle of motor vehicles 2 and serves as electromotor at recovery stage, in braking procedure, produced braking energy is converted into electric energy. Then in order to reduce the brake pressure of brakes 12 at recovery stage, it is provided that a relief valve unit 36, for reducing the brake pressure existed at wheel drag 22,24 place of front vehicle wheel 4,6 in a corresponding way. In the present example embodiment, relief valve unit 36 is by for constituting by one of pressure hydraulic pressure unit 38 separately. Hydraulic pressure unit 38 is connected on a hydraulic actuator 42 via 34 logical servo valves 40. Brake pressure can be increased or decreased by means of this hydraulic actuator 42, and its result is that brake pressure can carry out adaptation (in this case for front axle) in the effective coverage of relief valve unit 36 in this recovery stage.
For this purpose it is proposed, main braking cylinder 20 has first piston and the second piston 44,46, the two piston is coupled to each other rigidly via the first connecting element 48. Main braking cylinder 20 is subdivided into three rooms 50,52,54 by piston 44,46. First Room 50 and the second Room 52 are designed to hydraulic pressure chamber, and wherein the second Room 52 has immutable volume by means of the first connecting element 48. In the current situation, 3rd Room 54 is filled with air and has compensating element, this compensating element, is implemented as compensation opening 56 and therefore define compensator 18 at this, and it is considered as the motion of destructive brake pedal 14 that this compensator avoids in the use procedure of relief valve unit 36. Additionally, in the present example embodiment, it is provided that having the steel spring element 58 more than 120 bar spring rates, this spring element makes first piston 44 be biased against stop element 60. Additionally, first piston 44 with braking direction opposite direction on be attached to by the second connecting element 62 on the piston 64 of hydraulic actuator 42 of relief valve unit 36. In addition, first piston 44 has and fluidly connects, so that the first Room and the second Room 50,52, the pass through openings 66 becoming possible, this pass through openings interacts with the region 70 of the first connecting element 48 in the first Room 50, and this region is designed to hollow and has opening 68. In the first Room 50, the part that the second connecting element 62 extends wherein has enclosure portion 72, and this enclosure portion is once carrying is shut off the pass through openings 66 in first piston 44. In the present example embodiment, hydraulic actuator 42 and main braking cylinder 20 be implemented as single type it is also possible to arrange dividually.
Hereinafter the description of brakes 12 is limited to the explanation of the effective coverage to relief valve unit (namely front axle). As long as the recovery of this electrically powered machine does not occur, brakes 12 acts as the brakes of routine, wherein braking procedure is via equalizer bar 16 and the first main braking cylinder 18 and to be passed to second Room 52 via the pass through openings 66 in the first piston 44 being carried on stop element 60 via pedal 14 triggering and brake pressure, and wherein the first Room 50 is fluidly connected to wheel drag 22,24 in known manner. Wheel drag 28,30 is fluidly connected to main braking cylinder 26.
If then starting recovery stage, then this necessarily causes the reduction of the brake pressure in front axle region. In this context, the piston 64 of hydraulic actuator 42 moves right, its result be the enclosure portion 72 of the second connecting element 62 be first shut off pass through openings 66 (in this regard referring to the position of the enclosure portion 72 in Fig. 2) and then first piston 44 move right equally, it causes in the first hydraulic pressure chamber 50 and therefore also has the pressure at wheel actuators 22,24 place to decline. Second piston 46 is also resisted the spring force of spring element 58 via the first connecting element 48 and is moved right and force air to leave from this compensation opening 56. The volume of the second Room 52 and pressure therefore remain unchanged, and its result is that of avoiding destructive reaction effect.
Fig. 2 illustrates the hydraulic circuit diagram of brakes 12 second embodiment in the passenger car as being conventionally used for road approval. Replace equalizer bar 16 (in this regard referring to Fig. 1), employ the simple lever being operatively connectable to the first main braking cylinder 18 ' at this and arrange 17. In this context, the first main braking cylinder 18 ' is designed to a tandem master cylinder at this, and this tandem master cylinder has two pistons 74,76 forming two hydraulic pressure chambers 78,80. In this context, hydraulic pressure chamber 78 is fluidly assigned to the wheel drag 28,30 of hind axle. Hydraulic pressure chamber 78 is comparable with the hydraulic pressure chamber of the first main braking cylinder 18 in Fig. 1 and together with the hydraulic pressure chamber 50 of main braking cylinder 20, the brake pressure acted on wheel drag 22,24 is responsible at this. There occurs that brake pressure declines at recovery stage, as depicted in figure 1.
Then Fig. 3 illustrates the embodiment slightly revised of main braking cylinder 20. Compensating element, is not designed as at this compensating opening 56, and is designed as the fluid connection line 57 between the 3rd Room 54 and hydraulic actuator 42. Alternatively, however, room 54 can also be connected to via fluid connection line compensate reservoir (not showing further).
Still stating, main braking cylinder 20 and hydraulic actuator 42 can also be arranged in the housing parts being separated from each other certainly.
