Following explanation earlier brake pressure control apparatus 10 of the present invention as shown in Figure 1, comprising: the fluid-pressure cylinder formula body 13 that possesses tubular inner space 11; Mode is inserted in this inner space 11 one end to move freely along the inner space 11 of body 13, and the other end stretches out the pull bar 14 of this body 13; Be arranged in above-mentioned pull bar 14 and be positioned at an end of the inner space 11 of body 13, and can be with pull bar 14 displacement piston 12 freely back and forth in inner space 11; Be arranged in the body 13, be set on the pull bar 14, two ends are connected to the upper end of piston 12 and inner space 11 respectively, in order to piston 12 is given the spring 15 of the elastic force that the below resets in the figure; And be formed on intercommunicating pore 110 in body 13 sidewalls, this intercommunicating pore 110 is in order to the inner space 11 that is communicated with body 13 and the brake fluid line of the vehicle, brake fluid line 52 for example shown in Figure 3, this intercommunicating pore 110 is located at inner space 11 latter ends below the reset position after this piston 12 resets by suppressing of spring 15, just at body interior space 11 sidewalls of piston below 12 of reset position, or the end wall in body interior space 11 is (with reference to figure 4A, shown in Fig. 4 B), as long as when pull bar 14 pulling pistons 12 move up, can produce suction in the inner space 11 of piston 12 below so that get final product from the position of the brake fluid line absorption brake solution that is connected.In addition, also a predetermined space S can be kept between the piston 12 of reset position and inner space 11 end wall, as Fig. 2 A, Fig. 4 A, so that the easier suction of the brake solution of brake fluid line, the concrete structure that this intercommunicating pore 110 is communicated with brake fluid line, available any prior art is not given unnecessary details in this article in addition.
In addition, body 13 is formed with axial through bore 130 in upper end wall to be run through for above-mentioned pull bar 14, and oil sealing (not shown) is set at these 130 inwalls of boring a hole, to avoid brake solution in the inner space 11 via the gap outflow of internal perisporium with 14 on the pull bar of perforation 130, or avoid after one is assembled in suspension system 30, the shock absorber oil of suspension system 30 enters inner space 11 via this gap.
Moreover the upper end that pull bar 14 stretches out body 13 is provided with stop block 14a with removably, and before this brake pressure control apparatus 10 will be assembled in suspension system 30, this stop block 14a can be unloaded, and during assembling, will use existing means to be fixed.
Below illustrate that by Fig. 2 A, Fig. 2 B brake pressure control apparatus 10 of the present invention is assembled in the example of existing suspension system 30.In this example, shock-absorbing body 33 lower ends that body 13 one of this brake pressure control apparatus 10 are assembled in suspension system 30 (promptly, shock-absorbing bar 31 stretches out the end opposite of side), pull bar 14 stretches out the upper end of body 33 and then inserts freely in the slotted hole 312 that is formed in the shock-absorbing bar 31 hypomere portions to move up and down, and utilization is located at the stop block 14a of pull bar 14 upper ends, when shock-absorbing bar 31 moves up because of load reduction, the elastic force that can spur pull bar 14 antagonistic springs 15 moves up, simultaneously with piston 12 in the lump to top offset, 11 lower end is formed with the space with negative-pressure sucking and in the inner space, this negative-pressure sucking is drawn brake solution via intercommunicating pore 110 from brake fluid line simultaneously, the brake weight of brake system is reduced, secondly, reply normal (the stable enforcement of self-propelled vehicle just at shock-absorbing bar 31 because of load, when the situation disappearance that load alleviates suddenly) moving down, its control power to pull bar 14 disappears, at this moment, pull bar 14 and piston 12 promptly are reset to the home position by the elastic force of spring 15, and the stop block 14a of pull bar 14 upper ends also is reset to slotted hole 312 bottom positions in the shock-absorbing bar 31, simultaneously, the brake solution that is inhaled into the inner space 11 of piston 12 belows is also pushed by piston 12 and gets back to brake system via brake fluid line, makes brake system reply original brake weight.
In this way, travel in that self-propelled vehicle is stable, under the situation that load can not alleviate suddenly, the shock-absorbing bar 31 of suspension system 30 and the pull bar of brake pressure control apparatus 10 14 and piston 12 all the position in minimum position, the brake solution of brake fluid line is not inhaled into the inner space 11 of brake pressure control apparatus 10, and when self-propelled vehicle shifts load forward because of emergency brake, shown in Fig. 2 B, the elastic force that is the spring 32 by suspension system 30 upwards pushes away shock-absorbing bar 32, makes its displacement.At this moment, shock-absorbing bar 31 and spur the pull bar 14 of brake pressure control apparatus 10 simultaneously and the elastic force of piston 12 antagonistic springs 15 and moving up, and form a negative pressure space S at the lower end wall and 12 in the piston of the inner space 11 of brake pressure control apparatus 10.Under this negative pressure space S effect, the brake solution of brake fluid line can be inhaled in this space S, so, the oil mass that flow to the fluid control valve (please refer to explanation hereinafter) of brake system via brake fluid line just can reduce, the brake weight of brake units is reduced, brake weight and wheel are dwindled, to eliminate the tyre skidding phenomenon that causes because of emergency brake by the gap of the friction force between ground.
See also Fig. 3, be applied to back suspension system 30 scheme drawings of self-propelled vehicle for brake pressure control apparatus of the present invention.
Self-propelled vehicle has the generation of load transfer effect (load transfereffect) in motion as if emergency brake.That is to say that under the situation of motional inertia, the past front-wheel of load meeting moves and reduce the pressure of trailing wheel, especially under the big more situation of brake power, its load transfer effect can be obvious more.In other words, when emergency brake, shifted owing to act on the load of the trailing wheel of this self-propelled vehicle, then can produce displacement so be installed in the shock-absorbing bar of the suspension system of trailing wheel, and the brake power is big more, and the displacement of this suspension system is also big more, and both can be considered a linear ratio relation.
Again, the power of brake of motor-driven vehicle is relevant with the clamp pressure of brake, and the clamp pressure of brake can be depending on the brake oil mass that brake pump flows into clamp, and the relation of single-piece parameter approximately presents as follows:
P: brake clamp pressure
β: bulk modulus (bulk modulus)
V: brake grease chamber volume
ΔV＝Vin-Vout
Vin: master cylinder flows into the brake oil mass of brake clamp
Vout: brake pressure control apparatus volume-variation amount
Vin=Ain * Hin (Ain: master cylinder sectional area, Hin: the master cylinder actuating length)
Vout=Aout * Hout (Aout: pressure control sectional area, Hout: the Shock absorber displacement)
Can know by inference by above-mentioned formula, when emergency brake or when desiring to provide big brake weight, the user can push brake system, and orders about the brake oil mass and flow into the brake clamp by master cylinder, reaches brake to improve brake clamp pressure.
But in the process of self-propelled vehicle emergency brake, because the relation of load effect transfer,, and cause the skid situation of brake power much larger than the trailing wheel frictional ground force so trailing wheel load meeting alleviates.Therefore, the present invention utilizes above-mentioned formula, reduces unnecessary brake power with the brake oil mass that lowers master cylinder inflow brake clamp.
Because during load reduction, the displacement meeting of the suspension system of this trailing wheel changes thereupon.Therefore, pressure-regulating device of the present invention promptly utilizes the mode of the change in displacement interlock of the shock-absorbing bar of being located at piston, pull bar and this suspension system in the device, and the brake oil mass that absorbs the brake fluid line of controlling trailing wheel is to reduce brake weight.
