Problems solved by technology
Due to the country's performance requirements for the safety performance of micro-tillers, the existing technology has gradually adopted normally open clutches, but the existing "normally open clutches" are difficult to meet the needs of the safety performance of micro-tillers. The problem is: the clutch is not completely separated, and the power output shaft cannot stop rotating within the specified time; due to the strong oil adhesion between the clutch friction plates, the separation between the clutch friction plates is not complete, and they adhere to each other. It can stop the output shaft of the tiller within 2 seconds (usually within 4-6 seconds) after the clutch is released, which has certain potential safety hazards and cannot meet the needs of national standards.

Embodiment
[0019] Embodiment: the tiller clutch in this program, as figure 1 As shown, it includes a housing, a driving shaft 5 and a driven shaft 1, and the driving and driven shafts 1 are located in the housing. The drive shaft 5 is spline-connected with the drive sleeve 3 , the drive sleeve 3 is spline-connected with the drive sleeve 13 , and the outer circumference of the drive sleeve 13 is fixedly connected with the first extrusion block 12 . Such as figure 2 As shown, the active sleeve 3 is rotatably connected with the carrier sleeve 11, and the carrier sleeve 11 is provided with several ring-shaped friction plates. A second extruding block 6 is fixedly connected to the outer periphery of the carrier sleeve 11 , and the friction plate is located between the first extruding block 12 and the second extruding block 6 . The friction plates include active friction plates 9 and driven friction plates 10 , the active friction plates 9 and the driven friction plates 10 are alternately a...

The invention belongs to the field of clutches, in particular to a mini-tiller clutch. The mini-tiller clutch comprises a driving shaft and a driven shaft. A driving sleeve is fixedly connected with the driving shaft. A transmission sleeve is fixedly connected with the driving sleeve. A first extrusion block is fixedly connected with the transmission sleeve. A carrying plate sleeve is rotationallyconnected with the driving sleeve. A plurality of friction plates are arranged on the carrying plate sleeve in a sleeving mode. A second extrusion block is fixedly connected with the carrying plate sleeve. The friction plates are located between the first extrusion block and the second extrusion block. A driven sleeve is fixedly connected with the driven shaft. Clamping holes are formed in the driven sleeve. Clamping plates are fixed to the friction plates and clamped into the clamping holes. A first reset spring is fixedly connected to the transmission sleeve. The end, away from the transmission sleeve, of the first reset spring is fixed to the driving sleeve. A shifting ring is in threaded connection with the driving sleeve and abuts against the transmission sleeve. A fixed friction ring is arranged on a motion path of the transmission sleeve. Through the mini-tiller clutch, the time required by a mini-tiller output shaft for stopping rotating after the clutch is released can be shortened.
Description
technical field [0001] The invention belongs to the field of clutches, and in particular relates to a tiller clutch. Background technique [0002] Due to the poor working conditions of the agricultural tillage machine (micro tillage machine), such as driving in the field or on the tractor road, higher requirements are placed on its power device, and higher requirements are also placed on the clutch of its power device. Due to the country's performance requirements for the safety performance of micro-tillers, the existing technology has gradually adopted normally open clutches, but the existing "normally open clutches" are difficult to meet the needs of the safety performance of micro-tillers. The problem is: the clutch is not completely separated, and the power output shaft cannot stop rotating within the specified time; due to the strong oil adhesion between the clutch friction plates, the separation between the clutch friction plates is not complete, and they adhere to eac...
