Abstract
The invention provides a timing mechanism capable of flexibly adjusting gas distributing phases. The timing mechanism comprises a spline shaft, an oil pipe, a camshaft and a gas distributing gear. The axis of the spline shaft is provided with a through oil hole, the two ends of the spline shaft are provided with outer spline teeth, and a relative displacement angle exists between the outer spline teeth at the two ends. The spline shaft is connected with the camshaft and an inner spline of the gas distributing gear through the outer spline teeth at the two ends of the spline shaft. The oil pipe penetrates through the oil hole of the spline shaft. The two ends of the oil pipe extend out of the spline shaft and are inserted in the camshaft and the gas distributing gear correspondingly. Compared with the prior art, the timing mechanism capable of flexibly adjusting the gas distributing phases has the following advantages that the spline shaft is subjected to grouping design by adjusting the relative displacement angle between the outer spline teeth at the two ends of the spline shaft to meet the adjustment requirements of gas distributing phase angles, the design is simple, and the production process and the assembly process are greatly simplified.
Description
Technical field
The invention belongs to engine drive mechanism field, especially relate to one and port timing can be adjusted flexibly

And the transmission idle pulley system of centre gets ready one by one to align and directly mates the initial phase of camshaft and bent axle and close
System.And crankshaft toothed wheel and bent axle phase position to be had relation, gas wiring gear also to have relative with camshaft
Position relationship.Therefore, the number of components that this phase matched method relates to is many, all brings to production and assembling
Complexity.
Summary of the invention
In view of this, it is contemplated that propose a kind of timing mechanism that port timing is adjusted flexibly, with letter
Change structure and the assembling of drive mechanism.
For reaching above-mentioned purpose, the technical scheme is that and be achieved in that:
The timing mechanism of port timing can be adjusted flexibly, including splined shaft, oil pipe, camshaft and distribution tooth
Wheel, is provided with the oilhole run through at the axle center of described splined shaft, its two ends are equipped with external spline teeth, and two ends
External spline teeth there is relative dislocation angle；
Described splined shaft connects the internal spline of camshaft and gas wiring gear respectively by the external splines at its two ends,
Described oil pipe is through the oilhole of splined shaft, and oil pipe two ends are extended splined shaft and insert camshaft respectively and join
Gas gear internal.
Further, in described gas wiring gear, the other end installs the supporting of spacing splined shaft, described distribution tooth
The two ends of wheel are arranged in transmission case by sliding bearing, and blanking cover, supporting are installed in one end of described transmission case
Outer face and blanking cover between be provided with back-up ring.
Relative to prior art, present invention have the advantage that
Splined shaft, by adjusting the relative dislocation angle of splined shaft two ends external spline teeth, is grouped by the present invention

Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in the present invention and the spy in embodiment
Levy and can be mutually combined.
Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
The timing mechanism of port timing can be adjusted flexibly, as it is shown in figure 1, include splined shaft 2, oil pipe 3,
Camshaft 1 and gas wiring gear 6, be provided with, at the axle center of described splined shaft 2, the oilhole run through, and its two ends are equal
It is provided with external spline teeth, and the external spline teeth at two ends exists relative dislocation angle；
Described splined shaft 2 connects the interior of camshaft 1 and gas wiring gear 6 respectively by the external splines at its two ends
Spline, described oil pipe 3 is through the oilhole of splined shaft 2, and splined shaft 2 difference are extended in oil pipe 3 two ends
Insert camshaft 1 and gas wiring gear 6 is internal.
In described gas wiring gear 6, the other end installs the supporting 7 of spacing splined shaft 2, described gas wiring gear 6
Two ends be arranged in transmission case 4 by sliding bearing 5, blanking cover 9 is installed in one end of described transmission case 4,
It is provided with back-up ring 8 between outer face and the blanking cover 9 of supporting 7.
Described splined shaft 2 one end couples with camshaft 1 internal spline, the other end and the interior flower of gas wiring gear 6
Key connecting.By adjusting the relative dislocation angle of splined shaft 2 two ends external spline teeth, splined shaft 2 is carried out point
Group design meets the adjustment requirement of valve timing diagram.
Described gas wiring gear 6 is operated by prescribed phases by splined shaft 2 drive cam shaft 1.Port timing
Determined by initial rigging position.Particularly as follows: described camshaft 1 is assembled to the position of phase requirements
Putting, the spline tooth angle of camshaft 1 determines therewith.The gear train of electromotor from the beginning of crankshaft toothed wheel,
After being assembled by the engagement of each gear, gas wiring gear 6 and inner spline gear thereof can be uncertain assemblings
On position, but due to the recurring cyclically of the gear teeth, the inner spline gear angle of gas wiring gear 6 can be at one
Fluctuation loop cycle in relatively-stationary smaller range.Inner spline gear by splined shaft 2 with camshaft 1
Coordinate, on the basis of the spline external tooth of the splined shaft 2 coordinated with camshaft 1, according in gas wiring gear 6
The fluctuation range of spline tooth and phase accuracy requirement, coordinate with gas wiring gear 6 splined shaft 2 other end
Spline external tooth carries out the packet design that misplaces, thus forms the packet spline of two ends spline tooth difference dislocation angle
Axle 2, it is achieved gas wiring gear 6 and the inner spline gear of camshaft 1 are same with the external spline teeth at splined shaft 2 two ends
Time coupling couple, and synchronize ensure that camshaft 1 port timing design requirement.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this
Within the spirit of invention and principle, any modification, equivalent substitution and improvement etc. made, should be included in
Within protection scope of the present invention.
