Description
Technical field
The utility model patent relates to a kind of position transducer mounting structure, particularly a kind of crankshaft position sensor mounting structure.
Background technology
Crankshaft position sensor is the signal receiving element receiving crank position timing signal tooth signal, and because crankshaft-position signal tooth is integrated on the belt pulley of bent axle, therefore, it is fixedly connected on the front cover shell of belt pulley usually.In prior art, first crankshaft position sensor is fixed on front cover shell, then, belt pulley is sleeved on bent axle, then tighten belt pulley bolt after signal teeth being aimed at crankshaft position sensor and make belt pulley and bent axle form the phase relation determined.Due to existing crankshaft position sensor as shown in Figure 1, it is located by the positioning section A of sensor head back segment, the coupling bolt passing mounting hole B by one is fixedly connected on front cover shell, its mounting plane C is perpendicular to sensor head axis, and with Pulley shaft line parallel, the two has nonadjustable phase relation relative to belt pulley circumference.Therefore, for ensureing the accuracy of crank position and timing signal, when playing bolt, bent axle and belt pulley can not relatively rotate, the phase place change of bent axle and belt pulley directly can form timing error, therefore belt pulley should process the syndeton determining the two phase relation before being fixedly connected with bent axle.The syndeton of this sensor is not suitable for belt pulley and is fixedly connected with the front engine without determining phase relation with bent axle, otherwise, bent axle can be caused to be fixedly connected with difficulty with belt pulley, just again need to have torn open once phase place change and having refilled.For this reason, need to improve.
Summary of the invention
The utility model object is for the deficiencies in the prior art, a kind of crankshaft position sensor mounting structure is provided, this mounting structure is by sensor main body one side senser engaging lug, the installation faying face of this engaging lug is perpendicular to belt pulley axis, and engaging lug two ends are provided with two bar holes, to form the adjustable syndeton of sensor and front cover shell position, the front engine without determining phase relation is fixedly connected with bent axle to be applicable to belt pulley, thus reduce or avoid the secondary between belt pulley and bent axle to assemble, improve efficiency of assembling and production efficiency.
For achieving the above object, the utility model adopts following technical scheme.
A kind of crankshaft position sensor mounting structure, comprises the engaging lug being located at sensor main body and the connecting hole being located at front cover shell; Described engaging lug is integrally formed in sensor main body side, and engaging lug two ends are formed with a mounting hole passed for bolt respectively, and this mounting hole is bar hole structure, and the sensor that engaging lug is formed is installed faying face and is parallel to sensor main body axis; Described connecting hole is formed respectively and is located on two projections of front cover shell, two connecting hole axis being parallel and be threaded hole; Two projection end faces form the supporting surface of engaging lug, and after front cover shell installs fixing and crank pulley assembling, this supporting surface is perpendicular to crankshaft pulley wheel axis.
Adopt the utility model of preceding solution, because crankshaft position sensor is installed on front cover shell by the engaging lug of sensor main body side surface, and its mounting hole is two of strip structure, when two projections have enough distances, crankshaft position sensor and front cover shell phase relation can suitably adjust.Therefore, tentatively be connected to after on front cover shell at crankshaft position sensor, even if after crank pulley and bent axle are fixed by bolt tightening, change in its phase place generation setting range, also the position by adjusting crankshaft position sensor makes it aim at signal teeth, guarantees that the timing signal of timing system is accurate.Be applicable to belt pulley and be fixedly connected with the front engine without determining phase relation with bent axle, can reducing or avoid the secondary assembling caused because misplacing to a certain extent, effectively improving efficiency of assembling.
Preferably, described connecting hole two ends are arc-shaped; Distance between described two projections is greater than two center of arc's distance sums of sensor main body detection section diameter and connecting hole.To guarantee that crankshaft position sensor has enough setting ranges.
Preferred further, described connecting hole both sides are concentric arc-shaped, and this both sides center of arc is arranged in described crank pulley in the heart.To guarantee that before and after the adjustment of position, sensor probe front end and signal teeth have the distance of setting, guarantee the accuracy of Signal reception.
The beneficial effects of the utility model are, be applicable to belt pulley and be fixedly connected with the front engine without determining phase relation with bent axle, sensor mounting location adjustable, effectively can reduce or avoid secondary to assemble, engine assembly efficiency is high.
