Background technology
Wet clutch is that clutch is immersed in fluid, and while its work, fluid is constantly in clutch friction
Flowed on face, or the lubricating arrangement by installing on the clutch takes fluid to clutch Outside, then pass through lubricating arrangement point
Flow on friction plate, play cooling and lubricating effect.
At present, with the fast development of reading intelligent agriculture equipment technology, the accounting of power shifting tractor commercially is year by year
Increase.The core component of power shifting tractor is wet clutch, and caused heat is often at work for wet clutch
Need enough lubrications to be cooled down, and then ensure that wet clutch is safe and reliable.Traditional wet clutch lubrication is to pass through
Oilhole on axle, fluid is transported to lubricant housings, thus be both provided with wet clutch installation axle control oil circuit and
Lubricant passage way, so the diameter of axle should meet requirement.But in space than narrow, the diameter of clutch shaft is tiny
Etc. in structure, above-mentioned lubricating arrangement just has very big limitation, it is difficult to meets that wet clutch works requirement.
Therefore, it is necessary to develop a kind of new wet clutch lubrication system, part own structural characteristics effectively are utilized,
Clutch lubrication oil is incorporated into the friction pair of clutch, it is ensured that lubrication and cooling between clutch friction plate, effectively solve
The arrangement difficulty of lubricating pipe, so as to improve the reliability of wet clutch.
Utility model content
The purpose of this utility model is to provide a kind of power shifting compact-sized, easy for installation, lubricant effect is good
Tractor wet clutch lubrication system.
The technical solution of the utility model is：Power shifting tractor wet clutch lubrication system, including：Transmission housing
Body, power input gear, needle bearing, clutch splined hub, clutch driven disk, clutch friction plate, clutch pressure plate, from
Clutch lubrication splined hub, clutch oil cylinder, power output spline shaft；It is defeated that power output spline shaft by spline sequentially passes through power
Enter gear, clutch lubrication splined hub, on clutch oil cylinder, clutch splined hub and power input gear are affixed, clutch flower
Key hub is connected by spline with clutch driven plate, and clutch friction plate is arranged on clutch lubrication splined hub by spline
On, clutch pressure plate is sleeved in clutch lubrication splined hub, and is bonded with clutch friction plate.
Needle bearing is provided between power output spline shaft and power input gear.
Power output spline shaft one end is fixedly set on gear box casing.
The first lubricating oil oil-in, the second lubricating oil oil-in, the first lubricating oil oil spout are provided with gear box casing
Hole, the second lubricating oil nozzle opening, the first lubricating oil oil-in are vertically connected logical with the first lubricating oil nozzle opening；Second lubricating oil enters
Hydraulic fluid port is vertically connected logical with the second lubricating oil nozzle opening.
The first oil-through hole, the second oil-through hole are provided with power input gear.
Using can reach following good effect after such scheme：Power shifting tractor wet clutch lubrication knot
Structure, the function of passing power is not only played, more play the function of being easy to lubricating pipe to arrange.It is effectively special using part self structure
Point, clutch lubrication oil is incorporated into the friction pair of clutch, it is ensured that lubrication and cooling between clutch friction plate, effectively solution
The certainly arrangement difficulty of lubricating pipe, so as to improve the reliability of wet clutch.
Brief description of the drawings
Fig. 1 is power shifting tractor wet clutch lubrication system diagrammatic cross-section.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.As shown in Figure 1：Power shifting tractor wet from
Clutch lubrication system, including：Gear box casing 1, power input gear 2, needle bearing 3, clutch splined hub 4, clutch from
Moving plate 5, clutch friction plate 6, clutch pressure plate 7, clutch lubrication splined hub 8, clutch oil cylinder 9, power output spline shaft
10 etc..
Power output spline shaft 10 sequentially passes through power input gear 2, clutch lubrication splined hub 8, clutch by spline
On device oil cylinder 9, clutch splined hub 4 and power input gear 2 are affixed, and clutch splined hub 4 is driven with clutch by spline
Piece 5 is connected, clutch friction plate 6 by spline be arranged on clutch lubrication splined hub 8 on, clutch pressure plate 7 be sleeved on from
In clutch lubrication splined hub 8, and it is bonded with clutch friction plate 6.Set between power output spline shaft 10 and power input gear 2
It is equipped with needle bearing 3.The one end of power output spline shaft 10 is fixedly set on gear box casing 1.
The first lubricating oil oil-in A, the second lubricating oil oil-in B, the spray of the first lubricating oil are provided with gear box casing 1
Oilhole C, the second lubricating oil nozzle opening D, the first lubricating oil oil-in A are vertically connected logical with the first lubricating oil nozzle opening C；Second profit
Lubricating oil oil inlet B and the second lubricating oil nozzle opening D is vertically connected logical.The first oil-through hole E, are provided with power input gear 2
Two oil-through hole F.
When pressure lubrication oil, first lubricating oil oil-in A, the second lubricating oil oil-in B enter out of gear box casing 1, from
First lubrication nozzle opening C and the second lubrication nozzle opening D spray, through power input gear 2 on the first oil-through hole E and second it is excessively oily
