Abstract

The utility model relates to a slider clutch used for an one-way mechanical delivery system, wherein, an assembly, also called a double-shaft assembly, is arranged in the deceleration box of a loader. The clutch adopts a slider-type structure and uses the speed difference of the inner track and the outer track; the clearing device and the helical teeth control the movement of the slipper, and transmit the drive torque through the meshing and detaching of the teeth to detach the inner track from the outer track. The slider clutch overcomes the disadvantage of the prior roller-type or the wedge-type overrunning clutch which transmits the torque through friction, and improves the reliability of the torque transmission and the reliability, thus prolonging the service life of the clutch and improving the work efficiency.

Summary of the invention
The purpose of this utility model be to overcome existing overdrive clutch assembly working life short, reliability is low, processing technology is complicated and defect of high cost, a kind of clutch that uses slide block structure is provided, improve the working life and the reliability of clutch assembly, and cut down finished cost, and then improve the power transmission performance of engineering machinery.The utility model is specially adapted to engineering machinery field, as the speed reducer of loader.
The clutch configuration that the utility model adopted comprises: inner ring, outer ring, slide block and resetting means.The inner ring of described clutch and outer ring coaxial rotation, the inner ring outside is provided with helical tooth, and the inboard, outer ring is provided with internal tooth.Described slide block is provided with external tooth and internal spiral tooth, and is sleeved on the inner ring outside by helical tooth, under the effect of resetting means and helical tooth, and the clutch of control inner ring and outer ring.Described resetting means adopts spring or magnetic substance, between slide block and inner ring end back-up ring, when inner ring and outer ring rotating speed not simultaneously, helical tooth forces slide block and outer ring internal tooth to break away from, at this moment the resetting means pressurized; When inner ring was identical with the outer ring rotating speed, resetting means oppositely promoted slide block and the engagement of outer ring internal tooth.When resetting means adopted magnetic substance, preferred version was to form the power that the same sex is repelled each other between slide block and end back-up ring.
Adopt the clutch assembly of described slide block structure, comprising: line shaft, outer ring gear, bearing, interior wheel, slide block and resetting means.Described line shaft comprises driving gear and input shaft, both can one processing, by bearings in gearbox; Described outer ring gear, and is combined with line shaft or throws off by interior wheel and slide block in line shaft outside coaxial rotation by bearings, in its inboard, outer ring internal tooth is set; Described slide block and interior wheel are between the inner ring and outer ring of outer ring gear, the slide block outside has external tooth, inboard that helical tooth is arranged, interior wheel is fixed on a side of line shaft gear, there is helical tooth in its outside, the internal tooth of slide block external tooth and outer ring gear can be meshing with each other and break away from, the helical tooth of slide block and interior wheel is meshing with each other, and makes slide block slide with respect to interior wheel; Resetting means adopts spring or magnetic substance, between slide block and interior wheel outer end back-up ring, with the helical tooth acting in conjunction, is controlling the motion of slide block.
The characteristics of this clutch assembly are: be with slide block in the interior outside of taking turns, when outer ring gear and line shaft rotating speed not simultaneously, helical tooth forces the internal tooth of slide block and outer ring gear to break away from, at this moment the resetting means pressurized; When outer ring gear was identical with the line shaft rotating speed, resetting means as spring, forced the internal tooth engagement of slide block and outer ring gear.
