[embodiment]
See also Fig. 1 to Fig. 4, auxiliary device stablized connected with clutch of the present invention comprises cylinder body 6, push rod, piston 7, return elastic component 11 and the hydraulic pipe line with cavity 63.One end of cylinder body 6 and an end of clutch master cylinder 20 all are fixed on the vehicle body shrouding 21, the other end of this cylinder body 6 is equiped with end cap 5 by the mode that is threaded, accompany cushion rubber 4 between this end cap 5 and the cylinder body 6, release from the thread pitch between end cap 5 and the cylinder body 6 to prevent the fluid in the cylinder body 6.Cylinder body 6 is provided with four tapped through holes that connect with cavity 63, and these four tapped through holes are equipped with a bleed screw 3 and three straight couplings 12 respectively, are covered with dust-proof cover 1 on this bleed screw 3.Have one as liquid entering hole 2 in these four tapped through holes, the straight coupling 12 on this liquid entering hole 2 links to each other with liquid container 1 by one section conduit 25, be connected with conduit 22 between all the other two straight couplings 12, and the neutral position of this conduit 22 is connected to the solenoid valve of often opening 13.
Push rod comprises first push rod 14 and second push rod 16 of flexible connection, one end of this first push rod 14 passes through hole 51, the cavity 63 of cylinder body 6 and the through hole 64 on the cylinder body 6 in the middle of the end cap 5 successively, and stretch into clutch master cylinder 20 and link to each other with clutch master cylinder piston (not shown) and with this piston interlock, the other end of this first push rod 14 is connected with an end of second push rod 16, and the other end of this second push rod 16 is connected with clutch pedal 17.The part that first push rod 14 is placed in cylinder body 6 cavitys 63 is provided with one section screw thread 23, is arranged with a piston 7 on this section screw thread 23, and by the clamping action of two nuts 23 piston 7 is fastened on first push rod 14.Piston 7 is divided into first cavity 61 and second cavity 62 with cavity 63, be provided with return elastic component 11 in this first cavity 61, this elastic component 11 is as pressure spring, this return elastic component 11 is set on first push rod 14, and its two ends respectively with piston 7 and cylinder body 6 butts, thereby this piston 7 makes clutch pedal 17 returns by driving first, second push rod 14,16 under the effect of return spring 11.Because when clutch pedal 17 rotates around fixed point, the tie point of this pedal 17 and second push rod can produce displacement and first push rod 14 is interfered with end cap 5 on Vertical direction as shown in Figure 1, influence the sealing of cylinder body, so first push rod 14 and second push rod 16 is hinged.
In order to realize the in good time control to solenoid valve 13, this auxiliary device also comprises a controller 26 and a speed probe 8.This controller 26 is connected the opening and closing with control electromagnetic valve 13 with solenoid valve 13.This speed probe 8 is connected with controller 26, and it is installed on the gear ring 9, and this gear ring 9 is installed on the fixed rotating shaft of clutch pedal 17, makes gear ring 9 follow clutch pedal 17 and rotates together.Speed probe 8 is transported to controller 26 with the tach signal (being the rotating speed of clutch pedal 17) of gear ring 9, and controller 26 is according to the signal that receives, and control electromagnetic valve 13 is opened or closed.Can discern the clockwise and anticlockwise of gear ring 9 for making controller 26, here the tooth Shape Design with each tooth 91 of gear ring 9 becomes inequality, because gear ring 9 rotating ratios are lower in the present embodiment, can be designed to by 6 degree, 7 degree, 8 degree ... the profile of tooth of graded profile, as shown in Figure 4.
In the present embodiment, all have seal groove on the joint of cylinder body 6 and vehicle body shrouding 21 and the end cap 5, oil sealing 10 is arranged in the seal groove, release from the through hole 64,51 that first push rod 14 is passed to prevent the oil in the cylinder body 6.Between end cap 5 and clutch pedal 17, dust-proof cover 2 19 is arranged, pollute the fluid in the cylinder body 6 to avoid dust to enter in the cavity 63 of cylinder body 6.
During not stepping on clutch pedal 17, this device is in free state, and first cavity 61 and second cavity 62 of liquid container 1, conduit 25,22, cylinder body 6 all are full of fluid, and solenoid valve 13 often leaves.During let slip the clutch 17, under the effect of second push rod 16 and first push rod 14, piston 7 is the direction motion shown in arrow among Fig. 2.At this moment, because of piston 7 moves, the volume of first cavity 61 reduces, and the volume of second cavity 62 increases.For the power that prevents pedal 17 increases, fluid needs from 61 discharges of first cavity and enters second cavity 62 by conduit 22, therefore solenoid valve 13 is opened (when brake petal was stepped in setting, controller 26 was not closed solenoid valve 13) time again, and then the fluid flow direction is the direction of arrow as shown in Figure 2.
Finish changing shelves, during loose clutch pedal 17, under the elastic force effect of return spring 11, piston 7 direction shown in the arrow in Fig. 3 moves.For guaranteeing the clutch smooth and steady combination, the return speed of piston 7 must be slowly, so can make fluid produce the rightabout power of spring force that produces with return spring 11 by the control oil hydraulic circuit, forces piston 7 slow returns.Fluid flow direction as shown in Figure 3, will produce and the rightabout hydraulic coupling of spring force this moment, forces piston 7 slow returns, only needs by controller 26 in good time control electromagnetic valve 13 unlatchings or close to get final product.Because piston 7, push rod 14,16, clutch pedal 17 constitute a piston---pedal linking mechanism, be installed in the tach signal that the gear ring 9 on clutch pedal 17 fixed rotating shafts produces by speed probe 8 collection, be sent to the unlatching of controller 26 and control electromagnetic valve 13 or close.When piston---during the return excessive velocities of pedal linking mechanism, the signal of speed probe 8 is input to controller 26, and controller 26 sends control signal after handling input signal, closes solenoid valve 13, and at this moment, hydraulic coupling increases, and linking mechanism return speed reduces; When piston---the return speed of pedal linking mechanism is crossed when slow, and the signal of speed probe 8 is input to controller 26, and controller 26 sends control signal after handling input signal, opens solenoid valve 13, at this moment, hydraulic coupling reduces, and linking mechanism return speed increases.So solenoid valve 13 is opened, closed to controller endlessly, reduces, increases hydraulic coupling, control piston---the slow return of pedal linking mechanism, thus guarantee the clutch smooth and steady combination.
