Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.
Example (b): as shown in fig. 1, 2 and 3, the ratchet clutch for positive and negative rotation with different protection torques comprises a joint fork connecting flange 1, wherein an oil nozzle 8 communicated with a spline connector 7 is arranged on the joint fork connecting flange 1, and the oil nozzle 8 is in threaded sleeve joint with the joint fork connecting flange 1. The lower end of the section fork connecting flange 1 is provided with a section pipe 2 which is integrally welded with the section fork connecting flange 1, a spline connector 7 which is sleeved with the section pipe 2 is arranged in the section pipe 2, 30 lock pins 12 which are distributed in an annular shape at equal intervals and are connected with the spline connector 7 in an inserting and embedding manner are arranged between the spline connector 7 and the section pipe 2, a large spring 10 is arranged between the lock pins 12 and the spline connector 7, and a small spring 9 which is sleeved with the large spring 10 is arranged in the large spring 10. The lower end of the spline connector 7 is provided with a shaft clamp spring 6 which is connected with the spline connector 7 in an embedded mode, and a hole clamp spring 15 which is connected with the spline connector 7 in an embedded mode is arranged between the shaft clamp spring 6 and the lock pin 12. A nylon washer 13 sleeved with the spline connector 7 is arranged between the hole clamp spring 15 and the lock pin 12, and a blocking pad 14 sleeved with the spline connector 7 is arranged between the nylon washer 13 and the hole clamp spring 15. 3 steel balls 11 which are distributed in an equidistant annular mode and are clamped and embedded with the spline connector 7 are arranged between the shaft clamp spring 6 and the hole clamp spring 15, and the steel balls 11 extend out of the inner hole wall of the spline connector 7.
