Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
A high-speed automatic separation clutch comprises an output shaft driven gear 6; the output shaft driven gear 6 is connected with a power device, the output shaft driven gear 6 is installed on a rear output shaft 7, the rear output shaft 7 is connected with a front output shaft 1 through a sliding clutch sleeve 2, a rotating speed oil pressure converter 5 is further installed on the output shaft driven gear 6, and the rotating speed oil pressure converter 5 inputs an oil pressure signal 4 to a clutch sleeve control oil cylinder 3.
The output shaft driven gear 6 and the rear output shaft 7 are respectively a front wheel power shaft and a rear wheel power shaft of the wheel.
A spring is arranged in the clutch sleeve control oil cylinder 3, and the clutch sleeve is driven by the spring to enable the front output shaft 1 to be meshed with the rear output shaft 7.
A piston is further arranged in the clutch sleeve control oil cylinder 3, a push rod is arranged on the piston, and the other end of the push rod is connected with the clutch sleeve sliding clutch sleeve 2.
And a spring and hydraulic oil in the clutch sleeve control oil cylinder 3 are respectively arranged on two sides of the piston.
The adjacent ends of the front output shaft 1 and the rear output shaft 7 are both arranged in the sliding clutch sleeve 2, and the adjacent ends are both provided with gears.
The invention relates to a novel high-speed automatic separation clutch; the rear output shaft of the driving rear axle is connected with the output shaft driven gear in a normal output state, the front output shaft of the driving front axle is connected with the output shaft driven gear in an engaging and separating way through the sliding clutch sleeve, namely, the front output shaft is engaged with and separated from the output shaft driven gear through the movement of the sliding clutch sleeve. Rotational speed oil pressure converter is used for producing oil pressure, rotational speed oil pressure converter 5 is an oil pressure induction system according to the pitot principle, can correspond the automatic conversion generation pressure oil to the rotational speed, the rotational speed of output shaft driven gear is high more the control oil pressure value that produces through rotational speed oil pressure converter then high more, the pressure value of control oil pressure corresponds very lowly when the low speed, 3 separation and reunion cover control hydro-cylinders of control oil pressure direct control drive sequence number, by the direct pulling slip separation and reunion cover motion of separation and reunion cover control hydro-cylinder, thereby realize the meshing and the separation of preceding output shaft power transmission among the novel high-speed automatic separation clutch automatically.
As shown in fig. 1, in this state of low-speed engagement, the rotation speed of the driven gear of the output shaft 6 is low, generally below 500 rpm, at this time, the oil pressure generated by the rotation speed oil pressure converter 5 and input into the oil cylinder through the oil pressure signal is low, which is not enough to drive the compression of the spring in the clutch sleeve control oil cylinder 3, the clutch sleeve control oil cylinder 3 controls the sliding clutch sleeve 2 to be at the right position of the engagement position under the action of the internal return spring force, the novel high-speed automatic separation clutch is in the low-speed engagement state, and the front output shaft 1 and the driven gear of the output shaft 6 are engaged and output. The front output shaft and the rear output shaft both output power simultaneously under the driving of the output shaft driven gear.
As shown in fig. 2, the high-speed separation state is shown, in this state, the rotation speed of the output shaft driven gear is higher, generally more than 500 rpm, at this time, the oil pressure input to the oil cylinder through the oil pressure generated by the rotation speed oil pressure converter is larger, enough to drive the piston in the clutch sleeve control oil cylinder to extrude the spring, the clutch sleeve control oil cylinder overcomes the internal return spring force to pull the sliding clutch sleeve to the left position of the separation position, the novel high-speed automatic separation clutch is in the high-speed separation state, the front output shaft is separated from the output shaft driven gear, and the front output shaft is completely separated from the output shaft driven gear with the serial number 6 without outputting. Only the rear output shaft outputs power under the drive of the output shaft driven gear.
The novel high-speed automatic separation clutch controls the pressure value of oil pressure through the serial number 4 automatically generated by the serial number 5 rotating speed oil pressure converter, thereby automatically realizing the motion of the sliding clutch sleeve of the control serial number 2, namely realizing the automatic meshing and separating functions of the clutch. The elastic force of a return spring in the oil cylinder can be controlled by adjusting the clutch sleeve with the control serial number 3, so that the adjustment of the working rotating speed value of the automatic separation point of the clutch can be accurately and conveniently realized.
