Background technology
At present, construction machinery transmission uses slip clutch, and its clutch includes clutch hub body shaft and friction plate
Deng part.It is in actual production to use integrated mechanism or welded structure due to the structural particularity of clutch hub body shaft more, it is whole
Body formula structure needs to cause the waste in material and man-hour for processed inside hub body more, and welded structure was due to welding
Thermal deformation in journey can cause the precision of clutch hub body shaft not reach requirement.It is inside clutch hub body in actual production to adopt more
Connected, will ensured in the design of internal spline and external splines higher with the external splines of multiple close-toothed internal splines and friction plate
Required precision, and also require higher for fit tolerance, also improve manufacturing cost while increasing manufacture difficulty.
The content of the invention
In order to solve the above technical problems, the utility model provides the novel clutch used inside a kind of construction machinery transmission
Device hub body axle and friction plate.The utility model clutch hub body shaft has evaded the shortcomings that monoblock type or welded structure, Ji Nengbao
Demonstrate,prove the accuracy of manufacture and largely save cost；The friction plate being used cooperatively with it can reduce manufacture to a certain extent
Precision, so as to reduce manufacture difficulty and cost.After clutch hub body shaft and friction plate assembling, resistance that lubricating oil passes through friction plate group
Power reduces, and radiating and cooling performance are good, can greatly improve the life-span of friction plate, and assembles simple.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of novel clutch hub body axle and friction
Piece, the hub body axle include clutch shaft and clutch hub；The clutch shaft is provided with the half the circumference of the sleeve where it joins the shoulder of circumferential formula, half the circumference of the sleeve where it joins the shoulder periphery
On be provided with step trough；The clutch hub is cylindrical, and the shelves platform of circumferential formula, shelves platform periphery are provided with clutch hub inwall
On be provided with step trough；The half the circumference of the sleeve where it joins the shoulder step trough is mutually clamped with shelves stepladders groove；It is provided with half the circumference of the sleeve where it joins the shoulder and shelves platform multiple corresponding
Mounting hole, straight pin is installed between half the circumference of the sleeve where it joins the shoulder mounting hole and shelves platform mounting hole；The clutch hub both ends are provided with a plurality of uniform
Rectangular through slot；The friction plate is arranged in clutch hub, and friction plate periphery is provided with what multiple and rectangular through slot cooperated
Rectangular flange.
It is further：The clutch hub, which is often held, is provided with six uniform rectangular through slot；The friction plate periphery is provided with
Six rectangular flanges to be cooperated with rectangular through slot.
It is interference fit between straight pin and half the circumference of the sleeve where it joins the shoulder mounting hole and shelves the platform mounting hole.
Compared with prior art, the beneficial effects of the utility model are：Clutch shaft and clutch hub are individually processed, and are avoided
The material of monolithic construction processing and the waste in man-hour, while both passes through step trough and multiple cylinder finger settings and tight
Gu it also avoid the thermal deformation of welded structure, this fabricated construction can not only ensure the precision but also very after assembling
Processing and manufacturing cost has been saved in big degree；The machine that clutch hub and friction plate are coordinated using multiple rectangular channels and rectangular flange
Structure, eliminates the fit structure of multiple splines, and assembling is relatively easy, and due on clutch hub multiple rectangular channels compared to conventional
Open grain structure its resistance it is small, lubricating oil can be quickly friction plate group cooling down, and radiating and cooling performance are good, can be with
Greatly improve the life-span of friction plate.
