Problems solved by technology

[0002] Among the clutches currently used in vehicles, most of them are friction clutches. Friction clutches are not only complex in structure, but also prone to clutch friction plate slipping, and their working performance is not very stable.
The Chinese patent application No. 200520053737.6 discloses a planetary gear clutch. Although it has stable performance and no torque transmission waste, it is only a friction method to control the clutch, and the clutch state is difficult to control.

Embodiment Construction

[0015] Referring to Figure 1 and Figure 2, in the present invention, the ring gear 3 fixed on the ring gear 1-4 of the planetary gear mechanism 1 meshes with the hydraulic motor gear 4 on the output shaft of the hydraulic motor 5 to transmit control force for control. A positioning bearing 2 is fixed between the ring gear 1-4 and the box body, the sun gear 1-1 is used as the driving part, the main shaft 9 is connected to the engine, and the planet carrier 1-2 is used as the driven part. The box is connected, and the main shaft 9 and the slave shaft 8 and the box body 6 are supported by bearings 7. The control mechanism of the hydraulic motor 5 consists of the single-chip microcomputer system 10, the accelerator sensor 11, the vehicle speed sensor 12, the brake switch sensor 13, the electromagnetic reversing valve 20, the electromagnetic speed regulating valve 16, the one-way valve 18, the overflow valve 17, and the accumulator. 15. The oil tank 19 is composed of the electromagneti...

Abstract

The present invention provides a satellite gear on-off device, composed of a planetary gear and a hydraulic motor. The output moment of the hydraulic motor controls either one of planetary gear three basic elements as controlled element via a transmission gear, the planetary gear has clutch and infinitely variable functions. The advantages of the invention is that ''off'', ''on'', ''semi on-off'' are conveniently controlled by controlling the planetary gear using the hydraulic motor, infinite variable speed is processed in a certain range, the device replaces the present friction clutch, the clutch of vehicle is intelligently controlled by electricity, instead of step the clutch pedal, greatly reducing labor intensity of driver. The clutch device complete replaces the fluid-flywheel clutch used in the present automatic transmission, and the performance efficiency is greatly enhanced, and having great utility value.

Description

Technical field: [0001] The invention relates to a clutch device, in particular to a planetary gear clutch device with two functions of stepless speed change and clutch. Background technique: [0002] Among the clutches currently used in vehicles, most of the clutches are friction clutches. The friction clutches are not only complex in structure, but also prone to slippage of the clutch friction plates, and their working performance is not very stable. The Chinese patent application number 200520053737.6 discloses a planetary gear clutch. Although it has stable working performance and no torque transmission waste, it is only a friction method to control the clutch, and the clutch state is difficult to control. Summary of the invention: [0003] The purpose of the present invention is to provide a planetary gear clutch device that uses a hydraulic motor to control and constrain the planetary gear mechanism to realize the two functions of continuously variable speed and clutch. ...
