Abstract
An installation structure of a locking mechanism of a cam axial position adjuster comprises a stator, a rotor and the locking mechanism. The locking mechanism comprises a locking pin, a locking spring, a clamping spring and a gasket. A locking mechanism installation hole is formed in the outer circle of the stator in the radial direction and a locking groove corresponding to the locking mechanism installation hole is formed in the outer circle of the rotor. The installation structure of the locking mechanism of the cam axial position adjuster solves the problems that in the prior art, when a cam shaft completely penetrates through a central hole of a rotor of a cam shaft phase position adjuster, a fastening nut is used for axial limiting, the radial wall thickness of the rotor is reduced, a locking mechanism installation hole cannot be formed in the axial direction and the requirements of clients cannot be met.
Description
Technical field
The utility model relates to a kind of camshaft to the mounting structure of position regulator lockable mechanism.
Background technique
Variable Valve Time can be optimized valve characteristic parameter, improve motor inlet and outlet performance, meet preferably motor at the requirement of high rotating speed and the slow-speed of revolution, large load power character, Economy, toxic emission during with little load, the whole engine performance that improves.Now, changeable air valve technology has become one of key technology of measured engine performance.
Camshaft to position regulator as the actuator of Variable Valve Time mainly by: sprocket wheel, stator, rotor, lockable mechanism form.Lockable mechanism comprises lock pin, spring, spring seat etc.The effect of this lockable mechanism is when camshaft is not worked to position regulator, for the relative position between the parts such as fixed rotor and sprocket wheel, stator.
Camshaft is installed on camshaft top to position regulator, and rotor and the camshaft to position regulator links together by camshaft conventionally to use bolt.When camshaft is not worked to position regulator, the parts relative positions such as lockable mechanism fixed rotor and sprocket wheel.When camshaft is started working to position regulator, hydraulic oil promotes lock pin, makes rotor and miscellaneous part remove stationary state.Rotor, under the promotion of hydraulic oil, drives camshaft to rotate, thereby realize, adjusts camshaft to the function of position.
Conventionally, camshaft is rotor and the laminating of camshaft end face to the fit system of position regulator and camshaft, thus restrictive axial displacement, centre of sprocket hole or add counterbore at rotor end-face and coordinate with camshaft cylindrical, thus limit radial displacement.Under this mounting type, camshaft is axial arranged to the common employing of lockable mechanism of position regulator, as shown in Figure 1, is axially provided with the mounting hole 6 for lockable mechanism on rotor 4, and wherein, lockable mechanism is mainly comprised of lock pin 1, locking spring 2 and spring seat 3; Corresponding above-mentioned mounting hole 6 is provided with locking groove 7 at bonnet 5 or sprocket wheel (another kind of form, not shown).During lockable mechanism work: hydraulic oil enters locking groove 7 by the hydraulic oil import 8 being arranged on sprocket wheel or bonnet 6, it is descending that promotion lock pin 1 overcomes locking spring 2 resistances, reaches the object of release.
Above-mentioned mounting structure is used for many years, but still comes with some shortcomings, and is mainly when camshaft passes completely through camshaft to the rotor bore of position regulator, by locking nut axial limiting, rotor radial wall thickness reduces, and lockable mechanism mounting hole cannot be set vertically, can not meet customer requirement.
Therefore, how addressing the above problem, is the content that the utility model will be studied.
Summary of the invention
In order to overcome above-mentioned technical problem, the utility model provides the mounting structure of a kind of camshaft to position regulator lockable mechanism.
For achieving the above object, the technical solution adopted in the utility model is: a kind of camshaft, to the mounting structure of position regulator lockable mechanism, comprises stator, rotor and lockable mechanism; Described lockable mechanism comprises lock pin, locking spring, jump ring and pad; On the cylindrical of described stator, be radially provided with lockable mechanism mounting hole; On the cylindrical of described rotor, corresponding described lockable mechanism mounting hole offers locking groove.
Related content in technique scheme is explained as follows:
1, in such scheme, be also provided with hydraulic oil import on described rotor, described hydraulic oil import arranges towards described lockable mechanism mounting hole.
2, in such scheme, in described lockable mechanism, one end of described locking spring acts on described lock pin, and its other end acts on described jump ring; Between described locking spring and jump ring, be provided with pad.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1, the utility model structure is disposed radially lockable mechanism mounting hole on the cylindrical of stator, and corresponding above-mentioned lockable mechanism mounting hole arranges locking groove on the cylindrical of rotor, avoided when camshaft is through camshaft during to the rotor bore of position regulator, due to the problem that causes locking pin-and-hole to arrange vertically of reducing of rotor radial wall thickness, thereby met client's demand.
2, the utility model is simple in structure, is easy to realize.
Accompanying drawing explanation
Accompanying drawing 1 is the axially mounting structure schematic diagram of the lockable mechanism of position regulator of prior art cam;
Accompanying drawing 2 is the utility model structural representation.
In above accompanying drawing: 1, lock pin; 2, locking spring; 3, spring seat; 4, rotor; 5, bonnet; 6, mounting hole; 7, locking groove; 8, hydraulic pressure filler opening; 9, stator; 10, jump ring; 11, pad.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Embodiment: as shown in Figure 2, a kind of camshaft, to the mounting structure of position regulator lockable mechanism, comprises stator 9, rotor 4 and lockable mechanism; Described lockable mechanism comprises lock pin 1, locking spring 2, jump ring 10 and pad 11; On the cylindrical of described stator 9, be radially provided with lockable mechanism mounting hole 6; On the cylindrical of described rotor 4, corresponding described lockable mechanism mounting hole 6 offers locking groove 7.
On described rotor 4, be also provided with hydraulic oil import 8, described hydraulic oil import 8 arranges towards described lockable mechanism mounting hole 6.
In described lockable mechanism, one end of described locking spring 2 acts on described lock pin 1, and its other end acts on described jump ring 10; Between described locking spring 2 and jump ring 10, be provided with pad 11.
In when work, hydraulic oil is entered and is only locked groove 7 by hydraulic oil import 8 place that arrange on rotor, and promoting lock pin 1, to overcome the spring resistance of locking spring 2 and jump ring 10 descending, thereby reaches the object of release.
This programme has solved and has passed completely through camshaft to the rotor bore of position regulator when camshaft, by under the mode of locking nut axial limiting, due to the problem that causes locking pin-and-hole to arrange vertically of reducing of rotor radial wall thickness; Met client's demand.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
