Problems solved by technology
This method has the following disadvantages: firstly, after the gear meshing is completed, the starter will work again, and the starting speed is relatively slow; secondly, the power transmission part of the device is driven by a series of driving gears and passive gears, the structure is complex, and the starting speed is increased. Burden of engine starting

Embodiment Construction
[0020] The starter gear pre-engagement system and its control method of the present invention will be specifically described below in conjunction with the accompanying drawings.
[0021] Such as figure 1 As shown, an automobile starter gear pre-meshing system is composed of a starter 1, a gear pre-meshing device 3, an output gear 4, and a hydraulic oil circuit. The gear pre-meshing device 3 consists of a blade 8, a screw 9, a working chamber 10, and a 11. Composed of working chamber partitions 12. The hydraulic oil is composed of a pressure switch 17, a stroke displacement switch 18, a hydraulic pump 6, a one-way valve 7 and a hydraulic cylinder.
[0022] The output shaft 2 right-hand end of starter 1 is recessed, and is close to the left-hand end of screw rod 9 (as figure 2 As shown), when the output shaft 2 moves to the right, the screw rod 9 is pushed out, and the screw rod 9 passes through the working chamber 10 and is fixedly connected with the output gear 4; The uppe...

The invention discloses a vehicle starter gear pre-engaging system and a control method thereof. The pre-engaging system consists of a starter, a gear pre-engaging device, an output gear and a hydraulic oil way; the gear pre-engaging device is mounted between the starter and the output gear, and consists of blades, a screw rod, a working cavity, a flat key and a working cavity separation plate; the working cavity separation plate, the blades and the output gear are fixedly connected to the screw rod in sequence from left to right; the working cavity is divided into left and right parts by theworking cavity separation plate; and an oil inlet of the working cavity communicates with the hydraulic oil way. Through the gear pre-engaging device, the gear ejecting phenomenon can be eliminated tothe greatest extent, the flexible engagement between the output gear of the starter and a flywheel gear ring of an engine is guaranteed, the service life of the output gear and the flywheel gear ringis prolonged, and the impact of the starter on the flywheel gear ring of the engine is reduced.
Description
technical field [0001] The invention relates to the field of internal combustion engine automobile starting, in particular to an automobile starter gear pre-engagement system and a control method thereof. Background technique [0002] During the starting process of the existing automobile, the ignition switch is turned to the start gear, and the electromagnetic switch pulls the shift fork to push the gear forward. If the teeth of the output gear of the starter are not aligned with the tooth grooves of the flywheel ring gear, the top teeth phenomenon will occur. At this time, the electromagnetic switch continues to push forward and pulls the torsion spring on the shift fork to make the output gear align. The flywheel ring gear creates pressure that presses the output gear into the tooth slots of the flywheel ring gear. If this happens frequently, the output gear and the flywheel ring gear will easily cause tooth surface pitting and tooth surface gluing under frequent stress ...
