Spring reset type starter without electromagnetic switch

Abstract

The invention discloses a spring reset type starter without an electromagnetic switch. The starter has the characteristics of simple structure, light weight, low cost, small occupied space, convenience for transportation, good waterproof performance and low voltage failure mode. The spring reset type starter comprises a shell; a motor is arranged at the left side in the shell; a planet gear shaft is arranged at the right side in the shell; an output shaft of the motor is connected with the planet gear shaft through a speed reducer; a one-way clutch rolling sleeve, a one-way clutch sliding sleeve and a one-way clutch gland are arranged in a one-way clutch; an output end of the planet gear shaft is connected with the one-way clutch; a starting gear is arranged at an output end of the one-way clutch rolling sleeve; a peripheral spiral spline is arranged on a shaft body of the planet gear shaft; a spiral spline pair is arranged in the one-way clutch sliding sleeve, and fits the spiral spline on the planet gear shaft; an electromagnetic brake rotor is fixed outside the one-way clutch sliding sleeve; and an electromagnetic brake stator is fixed at the right side of the inner wall of the shell, and encircles the the electromagnetic brake rotor.

Description

technical field [0001] The invention relates to a starter, in particular to a spring return starter without an electromagnetic switch. Background technique [0002] Existing starters usually start the starter by activating the electromagnetic switch, driving the shift fork lever to push out the starter gear and make the starter gear mesh with the engine ring gear to start the starter, and the starter gear is completed by the electromagnetic switch return spring, etc. retraction reset, it has the following deficiencies: [0003] 1. Due to the use of the electromagnetic switch and the fork lever, the electromagnetic switch will be installed in parallel with the starter body. Due to the complex shape and structure, the waterproof function is not easy to realize. [0004] 2. Due to the use of electromagnetic switches and shift fork levers, the starter is large in size and irregular in shape, and it takes up more space during transportation, and it is often due to electromagneti...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the use of the electromagnetic switch and the fork lever, the electromagnetic switch will be installed in parallel with the starter body. Due to the complex shape and structure, the waterproof function is not easy to realize

[0004] 2. Due to the use of electromagnetic switches and shift fork levers, the starter is large in size and irregular in shape, and it takes up more space during transportation, and it is often due to electromagnetic switches and engine components during installation to the vehicle engine. The corresponding structural adjustment of the starter or engine due to interference

[0005] 3. The electromagnetic switch starting system involves switches, fork levers, electromagnetic switch return springs and other mechanisms, with complex structure, many consumables, heavy weight and high cost

[0006] 4. Due to the complex structure and high requirements on the carrying capacity of the battery, there are many failure modes

If the voltage of the car battery is low, the electromagnetic switch will not pull in and the whole machine will not operate.
