TH31052B - Single cylinder engine clutch disconnect / disconnection detection - Google Patents

Abstract

DC60 (13/07/54) The purpose is to detect the connection/disconnection of the centrally arranged clutch. Between the crankshaft of a single cylinder engine and the transmission path for the shaft's output power crank with high precision The coefficient of variation of the crankshaft rotation 7 is detected by the detection method. The rotation variation coefficient 16 and the judgment trajectory 17 determine the connection/disconnection of the clutch 11 by comparing the rotation variation coefficient detected by The method of detecting the variation coefficient of rotation 16 with the threshold value defined initially. Its purpose is to detect the connection/disconnection of the centrally provided clutch. Between the crankshaft of a single cylinder engine and the transmission path for the shaft's output power crank with high precision The coefficient of variation of the crankshaft rotation 7 is detected by the detection method. The rotation variation coefficient 16 and the judgment trajectory 17 determine the connection/disconnection of the clutch 11 by comparing the rotation variation coefficient detected by The method of detecting the variation coefficient of rotation 16 with the threshold value defined initially.

Claims (2)

1. The drive assembly device (5,9,11), which is assembled with Four-stroke (5) single-cylinder engine, clutch (11) provided between the crankshaft (7) of the aforementioned single-cylinder engine (5) and the powertrain (9) for the transmission of power output of Such crankshaft (7) and clutch disconnect / detachment system for single-cylinder engines. Used for detecting clutch disconnection / disconnection (11), it is unique in that The detection system is also included. A method for knowing the coefficient of rotation (16) was used to calculate it. The crankshaft rotational variation coefficient (TSRAT) (7) is based on the ratio between The difference between the timing (TSH4) of the crankshaft timing and the time (TSA4) of the upper compression stroke and the time (ME4U) required to complete two full turns of the crankshaft (7) on the other side, and - trajectory. A judgment (17) is used to determine if the clutch (11) is in a disconnected or disengaged state. By comparing the aforementioned Rotational Variation Coefficient (TSRAT) detected by the aforementioned rotational variation coefficient (16) with the initial threshold threshold (TSRAT). 2. Drive assembly equipment (5,9,11) as indicated in Claim 1, where the said threshold value (TSRATS) was initially set in accordance with the engine speed.
