RU2659771C1 - Method of gearshifting in a gearbox by magnetic-hydraulic clutch and spring gearshifting - Google Patents

Abstract

FIELD: machine building.

SUBSTANCE: invention relates to method of gear shifting control. Rotation energy for a gearshift is taken from a power shaft, which is transmitted to a toggle via a magnetic-hydraulic clutch. Toggle rotates, transmits the push rod of the transmission shut-off to the original position to disengage the transmission position and squeezes the transmission shut-off spring. In this case, the push rod of the gearshift is fixed by the hitch of the push rod of the transmission shut-off. Toggle continues to rotate, transmits the push rod of throw-in gear into the initial position to turn on the gear position and compresses the push rod spring of the throw-in gear. In this case, the push rod of the throw-in gear is fixed by the hitch of the throw-in gear push rod, after which the control system turns off the magnetic-hydraulic clutch. To throw in the transmission, the control system applies a voltage to the electromagnet of the transmission push rod. Push rod of the transmission pusher, being attracted by the electromagnet of the push rod of the throw-in gear, releases the throw-in gear push rod, which, under the action of the push rod spring, with the rod of the shift lever carriage fork throws-in the gearing. To turn off the transmission, the control system applies a voltage to the electromagnet of the gearshift push rod. Pusher's push rod, being attracted by the electromagnet of the pusher of the push rod of the gearshift, releases the push rod of the transmission shutdown, which, under the action of the pusher-spring of the transmission shifter, shuts the transmission off.

EFFECT: reduced shifting cycle, gearshifting is achieved.

Description

FIELD OF TECHNOLOGY

The invention relates to the field of engineering.

BACKGROUND

The closest prototype of the claimed invention is "Automatic transmission of a vehicle", RF patent 2056305

OBJECT OF THE INVENTION

The purpose of the claimed invention is to reduce the time on / off gears in the gearbox in various industrial mechanisms and transmissions of mechanical vehicles with a magnetic-fluid clutch and a spring-loaded gear selector.

SUMMARY OF THE INVENTION

When voltage is applied to the magnetization coil of the magnetic-fluid clutch, the magnetic fluid of the magnetic-fluid clutch becomes solid (the input and output shafts of the magnetic-fluid clutch clutch). The rotation energy for gear shifting in the gearbox is taken from the power take-off shaft of any machine, for example, an electric motor, which through the input shaft of the magnetic fluid clutch 1 (see figure), the magnetic fluid clutch 2 and the output shaft of the magnetic fluid clutch 3 is transmitted to the crank 4. The crank 4 rotates, puts the gear shift pusher 5 to the initial position to turn the gear off (as shown in the figure) and compresses the spring of the gear shift pusher 6. The pusher gear off 5 is fixed by the hook of the gearshift pusher 7. The crank 4 continues to rotate, puts the gearshift pusher 8 into the initial position for shifting the gear and compresses the spring of the gearshift pusher 9. In this case, the gearshift pusher 8 is fixed by the gearshift pusher 10, after which the system control turns off the magnetic fluid clutch 2. To engage the transmission, the control system supplies voltage to the electromagnet of the gear follower 11. The trigger of the gear shifter 10, being attracted by the electromagnet of the gear of the gear shifter 11, releases the gear shifter 8, which, by the action of the spring of the gear shifter 9, moving to the right, engages the gear with the fork of the shift carriage 12, and the gear lock 13 fixes the fork of the gear shift carriage 12 in the gear position. To deactivate the transmission, the control system supplies voltage to the electromagnet of the gearshift pusher 14. The hook of the gearshift pusher 7, being attracted by the electromagnet of the gearshift pusher 14 releases the gearshift pusher 5, which, under the action of the gearshift push spring 6, moves to the left by the carriage fork rod the gear selector 12 turns the gear off, and the gear lock 13 locks the fork shaft of the carriage of the gear selector 12 in the off gear position.

SUMMARY OF THE INVENTION

A method for controlling a gear shift in a gear box by a magnetic fluid clutch and a spring gear selector including a magnetic fluid clutch, a crank, a transmission pusher, a transmission pusher spring, a gear shift pusher, a transmission pusher, a transmission pusher spring, gear shift pusher hook, control system, gear shift pusher hook electromagnet, gear shift pusher hook electromagnet , the rod of the fork of the carriage of the gear selector and the electromagnet of the clutch of the pusher for disengaging the transmission, characterized in that the rotational energy for shifting the gears in the gearbox is taken from the power take-off shaft of any machine, which is transmitted to the crank through the included magnetic-fluid clutch, the crank rotates, translates the pusher gear shift to the initial position to turn the gear off and compresses the spring of the gear shift pusher, the gear shift pusher is fixed by the hook of the push To deactivate the gear, the crank continues to rotate, restores the gear shift pusher to the initial position for gear shifting and compresses the spring of the gear shift pusher, the gear shift pusher is fixed by the gear of the gear shift pusher, after which the control system disengages the magnetic-fluid clutch, and the control system turns on the gear supplies voltage to the electromagnet of the gear follower pusher, the gear of the gear stick pusher, being attracted by the electromotive hook dumpling the gear, releases the gear pusher, which, under the action of the gear shift pusher spring, engages the gear with the plug fork of the transmission carriage, the control system supplies voltage to the gear pusher hook electromagnet, the gear shift pusher hook, being attracted to the gear shift pusher solenoid, frees the gear shift pusher, which, under the action of the gear shift pusher spring, reklyuchatelya gear off transfer.

DETAILED DESCRIPTION OF THE INVENTION

The costs of research and development and the production of the claimed invention cannot differ significantly from those in the design and manufacture of classic gearboxes.
