Problems solved by technology
The traditional overrunning clutch can only be activated or deactivated by the input conditions of the active raceway, but not by the output state of the driven raceway
Therefore, the use of traditional overrunning clutches cannot realize multi-stage automatic transmission in a wide range.

Embodiment Construction
[0020] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.
[0021] see figure 1 and figure 2 , the centrifugal overrunning clutch provided by the present invention combines the characteristics of the centrifugal clutch and the sprag type overrunning clutch. The intermediate star shaft 1 of the clutch is evenly distributed with grooves 6 that are large on the outside and small on the inside. The grooves 6 are provided with centrifugal Wedge 2, the bottom end of the groove 6 and the bottom end of the centrifugal wedge 2 are arc-shaped to match, and the radius of the arc at the bottom of the centrifugal wedge 2 is smaller than the radius of the arc at the bottom of the groov...

The invention discloses a drive system of a hybrid vehicle using a centrifugal overrunning clutch. The drive system comprises an internal combustion engine, a first pneumatic motor, a clutch, a second pneumatic motor, and an output unit, wherein the output unit comprises a first input end, a second input end and an output end, and the drive system is characterized in that the clutch is the centrifugal overrunning clutch; the internal combustion engine is connected with the first input end of the output group sequentially through the first pneumatic motor and the centrifugal overrunning clutch; the second pneumatic motor is connected with the second input end of the output unit; the output end is driven by the first input end and the second input end of the output unit together; and the first pneumatic motor and the second pneumatic motor are connected with a gas storage cylinder by a control valve system. The invention has the following advantages that the starting condition of the centrifugal overrunning clutch is determined by the rotation speed of the output shaft, thus the hybrid power allocation in an automatic transmission system and the drive system of the hybrid vehicle is achieved, the full-distance continuously variable transmission can be achieved and the utilization rate of fuel is increased.
Description
technical field [0001] The present invention relates to a drive system of a hybrid vehicle using a centrifugal overrunning clutch. Background technique [0002] Clutches have a wide range of uses in the technical field of mechanical transmissions. There are many types of clutches in use now. Currently, the clutches that are specifically applied to the reduction box of the vehicle power system are mainly overrunning clutches. The overrunning clutch uses the speed change of the main and driven raceways or the transformation of the rotation direction to realize self-clutching. When the speed of the driving raceway is the same as that of the driven raceway, power can be transmitted, otherwise they are relatively slippery. The traditional overrunning clutch can only be activated or deactivated by the input condition of the active raceway, but not by the output state of the driven raceway. Therefore utilize traditional overrunning clutch and can't realize multi-stage automatic sh...
