(54) ГИДРОСТАТИЧЕСКАЯ. МУФТА(54) HYDROSTATIC. COUPLING

-1 -one

Изобретение относитс к машиностроению , в частности к устройствам дл передачи вращени .The invention relates to mechanical engineering, in particular to devices for transmitting rotation.

Известна гидростатическа муфта, содержаща вращаки шйс корпус и расположенные в нем элементы гидронйсоса l .A hydrostatic clutch is known, comprising a rotary body and the elements of the hydraulic unit l located therein.

Недостатком этой муфты вл етс большой вес и габариты.The disadvantage of this coupling is the large weight and size.

Наиболее близкой по технической сущности и достигаемому реаультату к ттредлагаемой вл етс гидростати-ческа муфта, содержаща вр цакицийс корпус расположенные в нем солнечн о шестерню и сателлиты, образующие шестеренные насосы, соединенные каналами с дроссельным устройством 2J,The closest to the technical essence and the achievable result to the proposed bid is a hydrostatic clutch, which contains a temporary casing located in it a sun gear and satellites forming gear pumps connected by channels to the throttle device 2J,

Однако и данна муфта сложна по конструкции.However, this coupling is complex in design.

Цель изобретени - упрощение конструкции .The purpose of the invention is to simplify the design.

Поставленна цель достигаетс . тем, что корпус выполнен с цилиндрическими углублени ми, а сателлитыThe goal is achieved. the fact that the body is made with cylindrical recesses, and the satellites

расположены в них, при этом каналы расположены по обе стороны от каждого сателлита.located in them, with the channels located on either side of each satellite.

На фиг. 1 показан продольный разрез предлагаемой муфты, разрез В-В на фиг. 3; на фиг. 2 - часть продольного разреза, муфта выключена; на фиг. 3 - разрез А-А на фиг. 1; на фиг. 4 - разрез Я-Б на фиг. 1.FIG. 1 shows a longitudinal section of the proposed coupling, section B-B in FIG. 3; in fig. 2 - part of the longitudinal section, the clutch is turned off; in fig. 3 shows section A-A in FIG. one; in fig. 4 is a sectional view IB in FIG. one.

На маховике 1, установленном на On the flywheel 1 mounted on

10 ведущем валу 2, закреплен корпус 3 с боковыми крышками 4 и 5. В углублени х-гиездах 6 корпуса 3 размещены сателлиты - ведущие шестерни 7, вход вше в зацепление с солнечной 10 to the drive shaft 2, the body 3 is fixed with the side covers 4 and 5. In the recesses of the housing 6 of the body 3 there are satellites - the driving gears 7, the latch is engaged with the solar

Claims

15 driven gear 8 mounted on the driven shaft 9. Gears 7-8 form gear pumps. In the cover 5 there is a spool 10 with springs II; connected by rods 12 with a collar 13, coupled to the control lever 14. In the cover 5, the channels 15 are provided, located on both sides of the satellites. In the collar 4, channels 16 are formed, extending to the teeth of gears 7 from the opposite side of the engagement. For supplying oil to the cavity of the coupling in the drive shaft, channel 17 is connected to the engine oil supply line, and channel 18 is provided to ensure oil circulation. Bypass gear 8 is provided in gear 8. The coupling works as follows. When starting up, the engine oil enters channel 17 into the coupling cavity and exits leading gears 7 through channels 16, housing 3 rotates with shaft 2, gears 7 drive gear 8 and oil is forced into channels 15, i.e. Each pair of 7-8 operates as a gear pump. Since the clutch is normally closed, the spool 10 under the action of the springs 11 is held in position G1IT1 of FIG. 1 and locks the channels 15. Therefore, after filling them, hydraulic plugs are formed which prevent the gears 7 from turning 8. The gears 7 drive the tester 8 and the rotation from the shaft 2 is transmitted to the shaft 9. The clutch is not absolutely rigid hydraulic coupling provides some torsional vibration damping, which is a positive factor. When the shaft 2 of the shaft 2 is overtaken, the clutch is maintained as follows. how hydraulic plugs are formed in the channels 15 located on the other side of the engagement. . The clutch is turned off by the lever 14, which, through the ring 13 and the gi 12, retracts the valve 10 to the position of FIG. 2, which opens the exit of oil from the channels 15 and its circulation through the path 15-19-16-15. The gear 7 runs around the gear 8. When the lever 14 is released, the spool 10 by the springs 11 slowly, due to the drosse 8 64 of the casting gap between the spool and the shaft 9, returns to its original position, ensuring smooth coupling engagement. 71l prevent the oil from overheating and de-airing when filling the coupling with oil, the channel 18j of the hydraulic valve is slightly smaller than the channel 17. This ensures that the oil circulates through the cavity of the coupling and passes it into the engine crankcase. In the cavity of the clutch, there is always a motor, which allows the engine to start from the transmission. The hardening of the oil in winter conditions does not impair the operability of the coupling, it remains closed and warms up when the engine is started. A positive effect is to increase durability, simplicity of construction, smoothness of inclusion and high efficiency.
