Description

Intelligent Control System of Motorcycle Clutch Shift

Technical field:

The utility model relates to motorcycle engine, is specifically related to the motorcycle automatic clutch/semi-automatic transmission intelligent control system and the concrete controlling method thereof that are made of clutch of motorcycle automatic control system, semi-automatic transmission control system.

Background technique:

The tradition clutch of motorcycle has two kinds: manual clutch and automatic clutch.Manual clutch is separation, a joint action step of finishing clutch by clutch cable, makes motorcycle realize gear shift, function such as start to walk, travel.Therefore the clutch of motorcycle backguy must be along the repeatedly crooked competence exertion effect in position and space that adapts with motorcycle, like this along with increasing with the clutch resistance of high-power motorcycle of backguy curved arc increases, the resistance that clutch cable and the friction of its sleeve pipe produce also will increase thereupon, serious wear when causing the backguy frequent operation, when pulling force is exaggerated than big and curved arc, backguy is ruptured easily, especially for high-power motorcycle, because the operation resistance of clutch of motorcycle itself is quite big, add the resistance of clutch cable, feel painstaking when making driver's operation, sometimes not only can not operate freely, also may cause clutch separation, engage insufficiently, cause clutch plate to burn out, skid, wearing and tearing are accelerated, produce a large amount of powder simultaneously, cause machine oil impurity excessive, accelerate complete machine mechanical wear, stop up oil duct when serious, cause scuffing of cylinder bore, embrace cylinder, the serious mechanical failure of the stuck grade of piston ring.And because the operating device of most of motorcycles is non-closed pattern, descend at severse weathers such as carwash or rain, snow, the clutch of motorcycle backguy contacts with water inevitably, cause its rust corrosion, reduce working life, if at severe winter, in a single day the clutch cable of water inlet freezes, and will cause clutch out of control.And most automatic clutches engage poor performance, can only apply on the small-power motorcycle at present, and cause the wearing and tearing of clutch plate easily, cause engine output can not pass to wheel effectively, not only engine power can't be brought into play fully, but also can reduce the working life of motor and clutch.

At present, the motorcycle gear shift mode roughly divides three kinds: artificial clutch has a grade gear speed change, automatic clutch that grade gear speed change and automatic clutch stepless speed change are arranged.Artificial clutch has grade gear speed change and automatic clutch to have two kinds of gear shift modes of grade gear speed change to carry out gear switch by artificial judgment, owing to be artificial judgment, makes the gear proportioning can not be in time and accurate; And artificial buty shifting is handled, and adds the continuous variation of road conditions, environment, and the attention of disperseing the driver easily is unfavorable for safe driving.And the automatic clutch stepless gear shift mode, motor not only oil consumption is bigger, and drivign belt damages easily, and can shorten the working life of motor.Owing to be belt transmission, the automatic clutch stepless gear shift mode only is suitable for the less handy type motorcycle of horsepower.Have in grade gear gear shift mode at automatic clutch, also there is the intelligent control system utilized to drive shift shaft and carries out gear shift, as publication number is that the Chinese patent of CN2761547Y discloses a kind of " the full-automatic gear change system of motorcycle ", this system comprises CPU module, speed of a motor vehicle sensing module, engine speed module and shift-up downshift controll block, engine speed and vehicle speed signal that the CPU module comparison process is gathered, and shift-up downshift signal conveys is carried out gear shift to the gear shift mechanical module move.But the plus-minus gear switch of this system's shift-up downshift control is failed and the clutch system cooperation, can't solve send out dashing in the initial starting shift process, steady phenomenon, and directly be connected, be subjected to the interference of other signal in the motorcycle electric system easily with CPU module.
