The invention relates to a transmission mechanism (5) of a starter. The transmission mechanism (5) comprises a gear shaft (9), an overrun clutch (11) matched with the gear shaft (9) through a spline, two shift fork discs (13) rotatably installed on the gear shaft (9), a shift fork (15) at least provided with a fork part (25), and a drive gear (17) installed on the gear shaft (9), wherein a tab (27) mutually acting with the shift fork disc (13) is formed on the fork part (25), the transmission mechanism (5) further comprises at least one retaining device (43) arranged on the shift fork disc (13), the at least one retaining device is in contact with the tab (27), so that the relative rotation between the shift fork disc (13) and the tab (27) is stopped. The invention further relates to the starter comprising the transmission mechanism. According to transmission mechanism of the starter and the starter comprising the transmission mechanism, the abrasion of the tab of the shift fork is prevented, so that the service life of the starter is prolonged.
Description
technical field [0001] The invention relates to a starter, in particular to a transmission mechanism of the starter. Background technique [0002] Before the engine can run under its own power, it must be started with the help of a starter. The starter generally includes an electric motor, a transmission mechanism that transmits the rotational motion of the electric motor to a gear of the engine to start the engine, and an electromagnetic switch that controls on-off of a circuit of the starter. The transmission mechanism of the starter usually includes a gear shaft, an overrunning clutch cooperating with the gear shaft through a spline, two shift fork discs mounted on the gear shaft, a shift fork interacting with the shift disc, and a shift fork mounted on the gear shaft. drive gear, etc. The gear shaft is usually connected at one end with a reduction mechanism installed on the rotating shaft of the motor by means of an overrunning clutch, and the driving gear is installed...
