Description

Technical Field

[0001] This utility model relates to the field of motorcycle technology, and in particular to a motorcycle clutch monitoring device. Background Technology

[0002] The basic function of a motorcycle clutch is to connect and disconnect the power between the engine and the wheels. Simply put, when the clutch is engaged, the engine's power is transmitted to the wheels, allowing the motorcycle to move; when the clutch is disengaged, the engine's power is not transmitted to the wheels, and the motorcycle will not move. A belt-driven clutch assembly includes a clutch drive pulley assembly, a clutch driven pulley assembly, and a belt connecting the two assemblies. Existing clutch assemblies lack the ability to monitor clutch speed, resulting in low accuracy in monitoring vehicle speed.

[0003] For example, Chinese Patent Publication No. CN215071984U, published on December 7, 2021, entitled "An Electric Motor Mounting Structure for an Electric Motorcycle", includes a housing and a housing cover. A clutch drive wheel assembly and a clutch driven wheel assembly are provided between the housing and the housing cover. The clutch drive wheel assembly and the clutch driven wheel assembly are connected by a belt. A detachable motor is provided on the outside of the housing, and the output shaft of the motor drives the clutch drive wheel assembly.

[0004] The drawback of existing patents is that existing clutch assemblies do not have the function of monitoring clutch speed, and the accuracy of monitoring vehicle speed is not high. Utility Model Content

[0005] The purpose of this invention is to improve the problem that existing clutch assemblies lack the function of monitoring clutch speed, resulting in low accuracy in monitoring vehicle speed, and to provide a motorcycle clutch monitoring device for monitoring clutch speed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A motorcycle clutch monitoring device includes a housing. Inside the housing are a belt-driven clutch drive wheel assembly and a clutch driven wheel assembly. The clutch driven wheel assembly includes a driven wheel with several circumferentially distributed protrusions on its inner edge. A speed sensor, cooperating with the protrusions, is mounted on the housing and positioned above the driven wheel. This motorcycle clutch monitoring device monitors the speed of the driven wheel through the interaction of the speed sensor and the protrusions, thereby monitoring the clutch speed and accurately monitoring the vehicle's speed. This provides accurate data for the vehicle's speedometer, allowing the driver to clearly and intuitively understand the vehicle's speed. The clutch driven wheel assembly includes a driven wheel. During the rotation of the driven wheel, the protrusions rotate along the central axis of the driven wheel. The rotation of the protrusions generates a change in magnetic resistance, inducing an AC electromotive force in the coil within the speed sensor. Measuring the magnitude of this electromotive force allows for the measurement of the corresponding speed value. This method monitors the clutch speed, achieving accurate monitoring of the vehicle's speed. Furthermore, the speed sensor is mounted on the housing, making assembly convenient; the speed sensor is located above the driven wheel, which facilitates the arrangement of the speed sensor's wiring harness on the top of the housing, resulting in a shorter wiring harness and simpler routing.

[0008] Preferably, the housing is provided with a mounting base for mounting a speed sensor, the mounting base being located above the driven wheel. The mounting base is used to fix the speed sensor. The mounting base being located on the housing facilitates the positioning and installation of the speed sensor.

[0009] Preferably, the speed sensor is bolted to the mounting base.

[0010] Preferably, the mounting base and the housing are integrally formed. The mounting base is easy to manufacture; it can be integrally formed with the housing.

[0011] Preferably, the protrusions are evenly distributed on the inner edge of the driven wheel.

[0012] Preferably, the inner edge of the driven wheel is bent inward to form a bent portion located inside the driven wheel. The bent portion is annular, and the protrusion is placed on the bent portion. In this technical solution, the inner side of the driven wheel refers to the side of the driven wheel facing the wheel. The outer edge of the inner side of the driven wheel is bent inward to form a bent portion located inside the driven wheel. The bent portion is used to improve the connection strength between the protrusion and the outer edge of the inner side of the driven wheel.

[0013] Preferably, the protrusion and the driven wheel are integrally formed.

[0014] Preferably, the speed sensor includes a probe that extends through the mounting base into the housing, and the probe engages with a protrusion on the driven wheel. The speed sensor, including the probe, comprises a sensor housing and the probe itself. The sensor housing is locked to the mounting base on the housing, and the probe extends through the mounting base into the housing, engaging with the protrusion on the driven wheel. During rotation, the protrusion generates a change in magnetic reluctance, inducing an AC electromotive force in the coil within the speed sensor probe.

[0015] Preferably, the speed sensor includes a terminal block, with the terminal block facing the end of the housing where the clutch drive wheel assembly is located. Wiring the terminal block towards the end of the housing where the clutch drive wheel assembly is located is advantageous because the clutch drive wheel assembly is connected to the motor; therefore, wiring the terminal block towards the motor direction results in shorter wiring and more convenient wiring.

[0016] Preferably, the housing includes an outer shell and an inner shell that fit together, locked together by a locking device, and the mounting base is placed on the inner shell. The housing includes a locked outer shell and an inner shell, with the mounting base placed on the inner shell. This facilitates the installation and detection of whether the speed sensor and the protrusion on the driven wheel are properly engaged.

[0017] Therefore, this utility model has the following beneficial effects: by monitoring the rotational speed of the driven wheel through the cooperation of the speed sensor and the protrusion, the speed of the clutch can be monitored, thereby achieving accurate monitoring of the vehicle's driving speed and providing accurate data for the vehicle's speedometer, allowing the driver to clearly and intuitively understand the vehicle's driving speed; the speed sensor is set on the housing, which is convenient for assembly; the speed sensor is located above the driven wheel, which makes it easy to arrange the speed sensor's wiring harness on the top of the housing, resulting in a shorter wiring harness and simpler wiring.
