The invention discloses a ratchet screw driver which aims at solving the problems that the existing orienting screw driver is inconvenient to hold by hand and has a complicated structure. The ratchet screw driver comprises a handle and a driver rod and is characterized in that the front end of the handle is provided with a pawl bed, wherein the pawl bed is provided with two pendular pawls arranged in the opposite directions and a shift part for controlling the position states of the two pawls, and the shift part is provided with two shift blocks which respectively correspond to the two pawls; the tail of the driver rod is provided with a ratchet sleeve, and the ratchet sleeve is sheathed on the pawl bed and is at least meshed with one of the two pawls; and an operating part which can be positioned on the handle is arranged and is used for changing the position of the shift part. By integrating all orienting structures at the front end of the handle, the ratchet screw driver has the advantages of simple and compact structure and convenient assembly and disassembly. Since a rotating sleeve is adapted to the outline wheel of the handle, the ratchet screw driver is kept adapted to the handle in shape in addition to facilitating gear shift, thereby facilitating being holden by hand for usage.

Neutral control is carried out during vehicle driving while decline in drivability is suppressed. During deceleration driving when the accelerator is not pushed, a C1 clutch pressure is gradually reduced in a state where an automatic transmission (12) is left in a current gear stage (GSN) (phase 2 control), and if a starting gear ratio input rotational speed (NINS) during deceleration driving becomes equal to or less than a predetermined rotational speed (NEIDL+ß), the C1 clutch pressure is reduced such that a clutch (C1) is completely released in a state where the automatic transmission (12) is placed in a first gear stage (phase 4 control). For example, if a certain speed (V) is reached, output torque (TOUT) is gradually reduced according to the gradual reduction of the C1 clutch pressure so as to suppress the uncomfortable sensation caused by variation in deceleration speed. In addition, for example if the certain speed (V) is reached, the clutch (C1) is in a slipping state, and when the accelerator is pushed and N control during driving is thereby cancelled, a sensation of slowness upon re-acceleration can be suppressed while engagement shock is also suppressed.

The invention discloses a drive belt tensioning device. The drive belt tensioning device comprises a bottom plate, a top plate, screws, driving nuts and nut sleeves. Supporting holes are formed in the bottom plate; mounting holes are formed in the top plate; the bottoms of the screws are arranged in the supporting holes; the top portions of the screws penetrate through the corresponding mounting holes; the driving nuts are meshed with the screws and can rotatably ascend or descend along the screws; a chain wheel is arranged on the outer side of the top of each driving nut; the four chain wheels are meshed with one transmission chain to rotate in a linkage mode; the four driving nuts ascend or descend synchronously; the tops of the driving nuts are in contact with the bottom of the top plate to jack the top plate. The nut sleeves are arranged above the top plate and are meshed with the screws, and the bottoms of the nut sleeves are in contact with the top of the top late. The four driving nuts are rotated; the four driving nuts are driven by the chain wheels and the transmission chain to be in linkage, and the four driving nuts rotatably ascend along the screws to jack the top plate to ascend.

The invention discloses a remote automatic control adjustable-speed disc magnetic coupling, and relates to the technical field of transmission in mechanical engineering. The magnetic coupling consists of a driving disc assembly, a driven disc assembly and a speed regulation device assembly, and is characterized in that: the speed regulation device consists of a micro motor, a speed reducing mechanism, a double threaded screw rod and a speed controller; the micro motor is arranged on a driven shaft of the driven disc assembly of the magnetic coupling; the speed reducing mechanism is arranged on an output shaft of the micro motor; the speed controller controls the micro motor to rotate and drives the double threaded screw rod to rotate through the speed reducing mechanism; and left and right ends of the double threaded screw rod are in threaded connection with a left driven disc substrate and a right driven disc substrate of the driven disc assembly respectively. The rotating directionsof threads at the two ends of the double threaded screw rod are opposite, when the double threaded screw rod rotates around the axis thereof, the left driven disc substrate and the right driven disc substrate of the driven disc assembly move close to or away from each other along the driven shaft of the magnetic coupling, so that air gaps among two groups of driven discs and driving discs are changed at the same time.

The invention relates to a wedge-block type one-way clutch. The surface of a star wheel inner hole is a smooth cylindrical face. A drive gear in a drive gear assembly is arranged in the star wheel inner hole, and the peripheral surface of the drive gear is a smooth cylindrical face. A plurality of wedge blocks are arranged between the star wheel inner hole and the periphery of the drive gear, and the multiple wedge blocks are tightly arranged to form a circle in a surrounding manner in the circumferential direction. Each wedge block is provided with a slotted groove with an opening located in the outer end of the wedge block. The bottom faces of the slotted grooves are inclining faces, and the inclining directions of the bottom faces of the slotted grooves of all the wedge blocks are the same. Elastic rings are embedded in the slotted grooves of the wedge blocks forming one circle in the surrounding manner and have inward tightening force for the wedge blocks forming one circle in the surrounding manner. Under the action of the tightening force of the elastic rings, the outer ends of the wedge blocks conduct wedge-caulking on the surface of the star wheel inner hole, and the inner ends of the wedge blocks conduct wedge-caulking on the surface of the periphery of the drive gear. The wedge-block type one-way clutch is compact in structure, ingenious in design, small in size, small in weight, large in transmission power and high in machining precision, and the one-way clutch can have more stable work performance, higher reliability and longer service life.
