Problems solved by technology

[0007] During the whole working process, the electromagnet and the return spring are frequently activated and are prone to failure
During maintenance, it is necessary to replace the electromagnet and the springs at the lower and upper ends of the shift fork, which is troublesome to maintain
And the spring return will bring impact to each component, and the positioning is not accurate; and there is a lot of noise

Abstract

The invention discloses a screw rod transmission starter and a control method thereof. The screw rod transmission starter comprises a control mechanism, a starting motor and a transmission mechanism,the control mechanism comprises a screw rod and a screw rod driving motor arranged at one end of the screw rod. The transmission mechanism comprises a single-way clutch slidably arranged on an outputshaft of the starting motor and a starting gear arranged on the single-way clutch. The screw rod is provided with a push rod, one end of the push rod is in fit connection with the screw rod, and the other end of the push rod is connected with the single-way clutch. When the screw rod drives the motor to drive the screw rod to rotate, the push rod moves left and right along the screw rod to drive the single-way clutch to move left and right along the output shaft of the motor, and thus the starting gear is engaged or disconnected with a flywheel gear ring of an engine. The starter is convenientto maintain, noise is low in the resetting process of the transmission mechanism, and the service life of the starter is prolonged.

Description

technical field [0001] The invention relates to the field of starters, in particular to a screw drive starter and a control method thereof. Background technique [0002] The function of the starter is to generate power through the DC motor, and drive the crankshaft of the engine to rotate through the transmission mechanism to realize the starting of the engine. [0003] The existing starter includes an operating mechanism, a starting motor, and a transmission mechanism; the operating mechanism is an electromagnetic operating mechanism; the electromagnetic operating mechanism is connected to the transmission mechanism through a fork mechanism; the transmission mechanism includes a one-way clutch installed on the output spindle of the starting motor and the starter gear mounted on the one-way clutch. [0004] When working, the operating mechanism is energized, the electromagnet is attracted, the upper end of the fork mechanism moves with the electromagnet, the lower end of th...
