The specific embodiment
The present invention is described further with embodiment below in conjunction with accompanying drawing 1～4.
When not working, brake roller 12 is in the brake disc groove 6, does not come in contact with brake disc.And when stepping on brake pedal in the brake, 11 motions of control line 2 pulling pull bars, brake roller 12 is gently moved to above the brake disc 4 by the inclined-plane of brake disc groove 6, and air pump 19 is started working.The dynamics of brake is strong more, and the distance of control line 2 pulling pull bars 11 is big more, and to the outer rim motion of brake disc 4, the radius from the axle center strengthens brake roller 12 more, and the resistance torque of brake is big more, i.e. N=F * R.So just the same with the similar mode of traditional brake facing, realized the purpose of mechanical control brake torque.During the releasing of brake pedal, under the effect of retracing spring 8, brake roller 12 is got back in the groove 6 of brake disc.
Referring to Fig. 3, aspect automatically controlled, during brake, brake pedal moves downward, brakes on source switch K1, and the relay J 1 of two one logical electromagnetic valves 24 is connected, and spool moves, and the valve opening that flows to high pressure tank 26 stations is opened.Air pump 19 is in compressed-air actuated mode of operation, and the suction hole aspirated air of air by electromagnetic valve 24 compressed, and the high pressure air gas piping 23 of compression enters in the high pressure tank 26 (high pressure tank 26 is equipped with safety valve) through air pressure control electromagnetic valve 25.Braking strength is strong more, and the slip variable resistance R resistance that is attached thereto is big more, and the electric current of the VT2 in the transistor amplifier is big more; The coil current of air pressure control electromagnetic valve 25 is big more, and magnetic force is strong more, and taper valve core 27 (see figure 4)s are closed tight more; Compressed air pressure increases; The rotating torque of air pump 19 strengthens, and brake torque also strengthens thereupon, has so just realized the purpose of automatically controlled brake torque.Comprehensively above-mentioned, brake has had the function of machinery and automatically controlled dual control brake torque.
Behind the releasing of brake, electrical controller is in off-position, plays the electromagnetic valve 24 of turnover gas control making usefulness and under pull back spring, gets back to midway location, and air inlet pipe and freeing pipe are closed, and high pressure air is stored in the high pressure tank 26, can not leak.
After autoclutch connects; During automobile starting, step on the throttle, Das Gaspedal and control line 2 link in mechanical aspects; 11 motions of control line 2 pulling pull bars; Brake roller 12 is gently moved to above the brake disc 4 by the inclined-plane of brake disc groove 6, and high pressure tank 26 is to air pump 19 air feed, and air pump 19 converts air motor at this moment into and drives brake disc 4 rotations.When Das Gaspedal moves downward, connect throttle source switch K2, the relay J 2 of electromagnetic valve 24 is connected, and spool is opposite with above-mentioned moving direction, and tracheae switches.Air pump 19 is in the mode of operation of air motor, and brake roller 12 promotes brake disc 4 and turns a wheel.Pressurized air in the high pressure tank 26 is got in the air pump 19 (air motor) through air pump gas piping 23 through air pressure control electromagnetic valve 25 by high pressure air, and the throttle dynamics is strong more, and the swept resistance R resistance that is attached thereto is more little; The electric current of VT2 is more little, and electric current is more little in the coil of air pressure control electromagnetic valve 25, magnetic force more a little less than; The effect (see figure 4) that taper valve core 27 is pushed open by valve spring 30; Aperture is big more, and the output compressed air pressure increases, and the rotating torque of air pump 19 strengthens; Staring torque strengthens, and has so just realized the function of machinery and automatically controlled dual control moment of starting.
The ABS function: see Fig. 3, when emergency brake of vehicle, the rotating speed of wheel reduces rapidly under the effect of brake system, and the tachogen of installing when wheel rim 22 positions 28 perceives wheel when being about to stop operating, and is given by tachogen 28 signals and sends signal i
vTo ABS control plate 29; ABS control plate 29 provides the input end that amplifying circuit in the electronic control package of brake is given in an instruction, and the coil current through regulating control air pressure control electromagnetic valve 25 reduces braking force, when wheel return to wheel when being about to stall again braking force reduce again; So repeatedly; Guarantee wheel not by locking, this action is very rapidly, approximately takes place each second tens times.Enough braking forces can be kept like this, vehicle get out of hand behind the wheel lockup can be prevented again.Particularly on wet and slippery road surface, wheel lockup can break away, spin, and is very dangerous.
