Technical Field

The invention relates to a controllable integrated overrunning reduction clutch, which is a combined integrated component with a reduction and clutch addition control mechanism. The reduction ratio can meet the requirement of transmission ratio from 2.4 to 13, and the device is mainly used for matching the front end output of a small-sized general gasoline engine (diesel engine) with the requirements of speed reduction and clutch with the front end input of a micro-cultivator of agricultural machinery or a field management machine.

Background

The output speed of the existing small-sized general gasoline engine (diesel engine) is high, and the existing small-sized general gasoline engine (diesel engine) has the requirements of low speed and clutch, and the front-end output has no speed reduction and external controllable clutch mechanism; the existing micro-tillage machines or field management machines of agricultural machinery require low speed and clutch; however, the front end input has the clutch which is only limited to the combination and separation of the motive power and the executing piece, and no speed reducing function and controllable mechanism are provided. The clutch and the speed reduction part used by the existing small-sized general gasoline engine (diesel engine), the mini-tiller of agricultural machinery or the field management machine have relatively large structural volumes, occupy large space volume and are not suitable for being used in working environments with small volume and working space requirements. The existing clutch is controlled by the speed centrifugal action of a machine, and is greatly influenced by the speed and the working condition, so that the machine is easy to stop and cause safety accidents.

Disclosure of Invention

The invention aims to provide a controllable integrated overrunning reduction clutch with a brand-new structure, and the speed reduction of the controllable integrated overrunning reduction clutch adopts the principle of a planetary reduction mechanism. The degree of freedom of the planetary reduction mechanism is controllable; during the clutch, the clutch action of the clutch is realized by limiting the degree of freedom of one part of the fixed planetary mechanism, and the output of power and speed is normally closed; the mechanism adopted in the control is an overrunning clutch mechanism, and the requirement on execution power is low. The planetary reduction mechanism and the overrunning mechanism are combined and integrated into an integrated component; the structure and volume are relatively small compared with a single clutch and planetary reduction.

The following technical scheme is adopted for achieving the purpose:

the planetary speed reducing mechanism comprises a planetary gear, a planetary carrier and a planetary gear ring, and three parts are integrated into one component. The power input sun gear is a single independent matched part. The planet carrier and the planet gear ring are parts which can control and fix the degree of freedom. The planetary gear, the planet carrier and the planetary gear ring are integrated into a component to realize respective autorotation and simultaneous deceleration; the speed reducing mechanism is integrated with an overrunning clutch mechanism. The overrunning clutch mechanism consists of a roller, a reset spring, a control panel and an outward extending rocker arm rod, the swinging of the rocker arm rod realizes that the overrunning clutch mechanism controls the rotation of the planetary gear ring, and the braking and releasing degrees of freedom realize the clutch; and power is output through the rotation of the planet carrier.

Detailed Description
