Embodiment 1

[0030] Embodiment 1 is a connection device for a crank angle sensor of a motorcycle engine with a displacement of 125CC.

[0031] The connecting device includes a driving shaft and a driven shaft, a rubber elastic coupling, a bearing end cover, a bearing seat, a bearing, a base plate and a flange.

[0032] The drive shaft has a drive shaft for the contact type crank angle sensor and a drive shaft for the non-contact crank angle sensor. The two drive shafts are composed of cylinders with the same axis. The two ends of the two drive shafts have threads respectively. and keyway. The thread on the left end of the driving shaft is connected with the crankshaft of the engine, and the keyway on the right end of the driving shaft is fixedly connected with one end of the rubber elastic coupling through a key. The length and diameter of the left end and the length and diameter of the right end of the drive shaft used to install the contact crank angle sensor are 36mm, 10mm and 25mm, 14...

Embodiment 2

[0040] Embodiment 2 is a connection device for a crank angle sensor of a motorcycle engine with a displacement of 150CC.

[0041] Compared with Embodiment 1, Embodiment 2 is different in that: the height of the bottom plate in Embodiment 2 is 25 mm.

Embodiment 3

[0042] Embodiment 3 is a connection device for a crank angle sensor of a motorcycle engine with a displacement of 250CC.

[0043] Compared with Embodiment 1, Embodiment 3 differs in that the bottom plate height in Embodiment 3 is 30 mm.

Abstract

The invention discloses a connecting device of a crank shaft turning angle sensor of motorcycle engines and relates to connecting devices of the crank shaft turning angle sensor that are used in the test of motorcycle engines, in particular to the connecting devices of the crank shaft turning angle sensor that are used in the fire test of motorcycle engines with high turning speed and large vibration. Two opposite ends of a drive shaft and a driven shaft of the connecting device are fixedly connected by an elastic rubber shaft joint, a bearing is arranged on the driven shaft and matched with astepped through hole at the middle part of the upper end of a bearing block, a bearing end cover is fixedly connected with the lateral surface of the bearing block, a flange disk is arranged on the drive shaft, the crank shaft turning angle sensor is arranged on the flange disk, and the bearing block is positioned on and fixedly connected with a baseboard that is fixed on a testing bench of motorcycle engines. The connecting device of the crank shaft turning angle sensor can effectively avoid the transmission of torsional oscillation information to the crank shaft turning angle sensor, has reliable and safe connection, and not only can measure turning speed and turning angle, but also can improve measuring precision and prolong the service life of the sensor.

Description

technical field [0001] The invention relates to a connection device of a crank angle sensor for motorcycle engine testing, in particular to a connection device of a crank angle sensor for motorcycle engine combustion testing with high rotational speed and large vibration. Background technique [0002] The prior art is to use the connecting shaft to connect the crankshaft of the crankshaft of the engine with the signal triggering part of the rotation angle sensor. This connection method cannot reduce the impact of the torsional vibration of the motorcycle engine crankshaft on the accuracy of the crankshaft angle signal, and the measurement accuracy is low; during the test, the threaded connection is easy to loosen, resulting in axial movement, or even falling off, damaging the crankshaft angle sensor. [0003] To study and improve the performance of the motorcycle engine needs to do a lot of bench tests, among which the crank angle signal of the motorcycle engine is a very im...
