Description

The demo system of vehicle automatic gear shifting

Technical field

The utility model relates to the technical field of vehicle automatic gear shifting control, is specifically related to the self-shifting demo system of a kind of electric-controlled mechanical.

Background technology

The demo system of vehicle automatic gear shifting still belongs to internal blank at present, existing vehicle automatic gear shifting demo system is fairly simple, the automatic gearbox teaching control system designed as Guilin aviation higher junior college, it utilizes single-chip microcomputer to control, come the gearshift of simulated automotive with diode, the shift process of automobile can not be demonstrated to the student relevant in the student of vehicle repairing factory and the universities and colleges with automobile major, also has the manual gear of vehicle testing table that Shanxi Prov. Inst. of Traffic Sciences developed, this test platform structure complexity, cost an arm and a leg, can not satisfy the needs of common universities and colleges and vehicle repairing factory.Automatic gearbox is of a great variety, complex structure, and principle is hard to understand, and the difficult point when being not only the auto repair personnel and keeping in repair also is the difficult point of universities and all kinds of student of training school study.

Present widely used automatic gearbox can't be watched its structure and drive path in the running, can't watch its drive path and principle of work again when taking apart and cutting open.Though existing books and reference materials have a lot, mostly just quote the simple introduction of former factory repair information, the general reader is difficult to understand its structure and principle of work.And for teaching, training, owing to do not have practical teaching aid and resources material, the teaching of automatic transmission is a difficult point always.

Summary of the invention

For the complex structure that overcomes existing vehicle automatic gear shifting demo system, cost height, deficiency that practicality is not strong, the utility model provides a kind of demo system of simple in structure, with low cost, practical vehicle automatic gear shifting.

The technical scheme that its technical matters that solves the utility model adopts is:

A kind of demo system of vehicle automatic gear shifting, comprise support, Power Drive Unit, self shifter mechanism and arrangement of clutch, support right-hand member position is equipped with arrangement of clutch, and arrangement of clutch right-hand member position is connected with Power Drive Unit, and self shifter mechanism is installed at the left end position of support; Described self shifter mechanism comprises stepper motor, shaft coupling, motor Connection Block, ball-screw, dial insert group becomes, one end of the axle connection shaft coupling of described stepper motor, stepper motor is fixed on the motor connection Connection Block, the other end of shaft coupling connects ball-screw, dials to insert to be installed on the ball-screw.

Further, described arrangement of clutch comprises input shaft, clutch coupling, clutch coupling holder and gear, and the left end of clutch coupling is fixed on the gear, and gear is fixed on the input shaft, the right-hand member of clutch coupling is fixed on the clutch coupling holder, and the clutch coupling holder is connected with the right-hand member of support.

Further, described Power Drive Unit comprises motor fixing seat and motor, and motor fixing seat is fixed on the right end position of clutch coupling holder, and motor is fixed on the motor fixing seat.

Technical conceive of the present utility model is: demo system has two kinds of functions: a kind of is by manual shift, and another is self shifter (size according to speed is selected gear).Manual shift: press start button, motor begins to rotate.Dial simultaneously under the driving that is inserted in stepper motor and get back to initial position.Press the Drive button then, dial this moment and under the driving be inserted in stepper motor gear is pushed a gear and put, after dialling plug in sensor and confirming to go up retaining, the clutch coupling adhesive.Two digital display meters show input and output speed respectively.The operator can be manually switched to according to the gear on the control panel any gear (reverse gear, one the retaining, two the retaining, three the retaining and four retainings).Press stop button at last and can stop the operation of total system.Self shifter: press start button, motor begins to rotate.Dial simultaneously under the driving that is inserted in stepper motor and get back to initial position.At this moment press the oiling button, the speed of motor can increase and decrease along with the length of the time of pressing.When the speed of motor reached a retaining speed that configures, system can give the alarm, and dials to insert automatically gear to be switched to two retainings.The principle of other gears is similar.But pass through the operation of stop button halt system at last.

Support is the basis that is used for installing whole equipment; Power Drive Unit provides the input power of total system; Self shifter mechanism is used for the switching of gear of the system that finishes; Arrangement of clutch is to be used for separating the device of importing power; Control system mainly is to be used for programmed control, signals collecting of the equipment of realizing etc.

The beneficial effects of the utility model mainly show: realize self shifter, and have manual shift and two kinds of operator schemes of self shifter, the equipment noise is low, price economy, simple to operate, safe and reliable, the vast industries relevant such as applicable and big-and-middle universities and colleges, vehicle repairing factory with automobile.
