Abstract
The utility model provides a cylinder head protective cover for an engine. A cylinder head protective cover body is provided with a position sensor mounting through hole and a position sensor fixing hole, wherein the position sensor mounting through hole and the position sensor fixing hole correspond to signal wheels; an embedded sleeve provided with internal threads is arranged in the position sensor fixing hole. The cylinder head protective cover for the engine has good connecting strength and is convenient to mount and dismount.
Description
Technical field
The utility model relates to engine cylinder cover, relates in particular to a kind of engine cylinder cover guard shield.
Background technique
Existing CMPS Camshaft Position Sensor is all arranged in engine cylinder and covers, and CMPS Camshaft Position Sensor is corresponding with the signal wheel on camshaft, for gathering the motor message of camshaft.Adopt this kind of layout can guarantee the precision of CMPS Camshaft Position Sensor, but when present motor adopts new structure (as ICS intercooler system, intake manifold placement variation etc.), can cause arrangement space not enough.Therefore, on existing cylinder cap guard shield, direct setting position sensor fixed hole is to fix position transducer, for ease of processing, position transducer fixed hole is generally unthreaded hole, bolt coordinates with nut after passing unthreaded hole and position transducer, and then position transducer is fixed, and unthreaded hole has gap while coordinating with screw rod, the connection of bolts and nuts easily occurs loosening, causes fixing insecure, the easy generation of position transducer loosening.Therefore, be badly in need of the mounting structure of CMPS Camshaft Position Sensor to improve.
Model utility content
In order to address the above problem, the utility model provides a kind of engine cylinder cover guard shield, can stationary cam shaft position sensor, and realize fixedly securing of CMPS Camshaft Position Sensor.
The technological scheme addressing the above problem:
An engine cylinder cover guard shield, described cylinder cap guard shield is provided with takes turns corresponding position transducer with signal through hole and position transducer fixed hole is installed, in described position transducer fixed hole, have be with female nested.
Selectable, the outer surface of described cylinder cap guard shield has boss, and described position transducer installation through hole and described position transducer fixed hole position are on described boss.
Selectable, it is stepped that described position transducer is installed through hole, forms a supporting surface.
Selectable, the internal surface of described cylinder cap guard shield is provided with strip stiffening rib at installation of sensors place, position.
Selectable, the material of described cylinder cap guard shield is glass fibre reinforced nylon.
The beneficial effects of the utility model:
On engine cylinder cover guard shield, setting position installation of sensors through hole and position transducer fixed hole, play the effect of stationary cam shaft position sensor, and then guarantee the normal work of displacement transducer; Position transducer is fixed on and on cylinder cap guard shield, has saved the arrangement space on cylinder cap; In sensor fixed hole, be provided with nested, nested internal thread and displacement transducer and be bolted, increased the effective length being threaded, there is good join strength, can realize fixedly securing of CMPS Camshaft Position Sensor.
Accompanying drawing explanation
Fig. 1 is the outer surface schematic diagram of the utility model embodiment's cylinder cap guard shield;
Fig. 2 is the sectional view of the A-A of Fig. 1;
Fig. 3 is the internal surface schematic diagram (nested not shown) of the utility model embodiment's cylinder cap guard shield.
Description of reference numerals: 1-engine cylinder cover guard shield, 2-position transducer is installed through hole, 21-supporting surface, 3-position transducer fixed hole, 4-is nested, 41-internal thread, 5-boss, 6-strip stiffening rib.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described in detail.
As shown in Figures 1 to 3, engine cylinder cover guard shield 1 is provided with signal and takes turns corresponding position transducer installation through hole 2 and position transducer fixed hole 3.Signal wheel is fixed on camshaft, position transducer is fixed on position transducer fixed hole 3, it stretches into the change in location that gathers camshaft in engine cylinder-body by position transducer through hole 2, in position transducer fixed hole 3, there is nested 4 with internal thread 41, in nested 4 embedded location sensor fixed holes 3.Nested 4 is metallic material, as nested in copper etc.Position transducer fixed hole 3 is through hole or blind hole.
Engine cylinder cover guard shield 1 can be thickeied to make it have better support effect in the part, installation place of position transducer, preferably, the outer surface of engine cylinder cover guard shield 1 has boss 5, and position transducer is installed through hole 2 and position transducer fixed hole 3 is positioned on boss 5.The size that the shape of boss 5 is installed through hole 2 and position transducer fixed hole 3 according to position transducer arranges, and the contour shape of boss 5 is rounding off.Adopt boss structure can strengthen the structural strength of displacement transducer installation place.
Preferably, the internal surface of engine cylinder cover guard shield 1 is provided with strip stiffening rib 6 at installation of sensors place, position.In addition, engine cylinder cover guard shield 1 also can be provided with latticed shape stiffening rib near position transducer installation through hole 2 places.Strip stiffening rib 6 is positioned at the internal surface of engine cylinder cover guard shield 1, and the number of stiffening rib can arrange as required.Stiffening rib has the effect that strengthens cylinder cap shroud structure intensity, reduces the distortion of displacement transducer installation place.
It can, for the diameter hole that is fixed value, can be also shoulder hole that position transducer is installed through hole 2.Preferably, it is stepped that position transducer is installed through hole 2, forms a supporting surface 21.Supporting surface 21 coordinates with the corresponding site of position transducer, guarantees that position transducer is fixing firm, firm.
The material of engine cylinder cover guard shield 1 can be selected glass fibre reinforced nylon, the nylon 66 that contains 35% glass fibre such as PA66-GF35().Cylinder cap guard shield can adopt glass fibre reinforced nylon, is conducive to motor lightweight.
Although the utility model is described in conjunction with above embodiment, but the utility model is not limited to above-described embodiment, and be only subject to the restriction of claims, those of ordinary skills can easily modify to it and change, but do not leave essence design of the present utility model and scope.
Claims (5)
