Embodiment 1

[0030] refer to figure 1 , figure 2 , Figure 8 , Figure 9 and Figure 10 , the present embodiment provides an automobile starter, comprising a rotor 1 and a stator 2, the stator 2 is a four-stage magnet cylinder, the magnet block 21 in the stator 2 adopts a Ru-Fe-B magnet, the inner area of ​​the magnet block 21 remains unchanged, and the magnet The thickness of the block 21 is reduced to half of the original thickness. A soft iron 22 is arranged between the magnetic block 21 and the inner wall of the stator 2. The thickness of the soft iron 22 is the same as or close to the thickness of the magnetic block 21. The magnetic block 21 is fixed by the soft iron 22. On the inner wall of the stator 2, without changing the size of the stator shell, the magnetic block is adapted to the size of the stator shell;

[0031] The automobile starter also includes a combination gear 5, and an inclined first slope structure 52 is provided on the outer end surface of the gear teeth 51 in...

Embodiment 2

[0033] refer to figure 1 , image 3 , Figure 8 , Figure 9 and Figure 10 , the present embodiment provides an automobile starter, comprising a rotor 1 and a stator 2, the stator 2 is a four-stage magnet cylinder, the magnet block 21 in the stator 2 adopts a Ru-Fe-B magnet, the inner area of ​​the magnet block 21 remains unchanged, and the magnet The thickness of the block 21 is reduced to half of the original thickness, and the magnetic block 21 is fixedly arranged on the inner wall of the stator 2 through the lateral fixing member 3. Since the thickness of the magnetic block 21 is reduced, the stator is reduced in size while adapting to the existing rotor 1 2 the size of the shell;

[0034] The automobile starter also includes a combination gear 5, and an inclined first slope structure 52 is provided on the outer end surface of the gear teeth 51 in the combination gear 5. The first slope structure 52 is a laterally inclined structure, and the first slope structure 52 T...

Embodiment 3

[0036] refer to figure 1 , Figure 4 to Figure 10 , the present embodiment provides an automobile starter, including a rotor 1 and a stator 2, the stator 2 is a six-stage rare-earth magnetic cylinder, the magnet block 21 in the stator 2 adopts a Ru-Fe-B magnet, and the stator 2 is sleeved and fixed with a cylindrical fixed Part 4, the cylindrical fixing part 4 is hard plastic, and the cylindrical fixing part 4 is distributed with magnet fixing grooves 41 along the circumferential direction, and the magnetic blocks 21 are evenly embedded and fixed in the magnet fixing grooves 41 one by one. The thickness of the cylindrical fixture 4 is the same as that of the magnetic block 21, the magnet fixing groove 41 is a through groove, and the inner wall and the outer wall of the magnetic block 21 coincide with the curved surfaces of the inner wall and the outer wall of the cylindrical fixture 4 respectively;

Abstract

The invention provides an auto starter and a method of fixing a stator inner magnetic block in the starter. The auto starter comprises a rotor (1) and a stator (2), wherein the stator (2) is a rare earth magnetic cylinder; the stator (2) is a four-stage magnetic cylinder or a six-stage magnetic cylinder; the magnetic block (21) in the stator (2) adopts a Nd-Fe-B magnet; the inner side area of the magnetic block (21) remains unchanged; and the thickness of the magnetic block (21) is narrowed half of the original thickness. The problems of insufficient magnetic strength of the existing starter and a limited driving force provided in the case of starting can be solved. The auto starter and the method belong to the field of vehicle engineering.

Description

technical field [0001] The invention relates to a starter and a fixing method for an inner magnetic block thereof, belonging to the field of vehicle engineering. Background technique [0002] The car starter is an indispensable and important part of the car. There are many types of car starters. The main difference is that the stator / magnetic cylinder of the starter is different, which leads to the difference in the performance of the starter. At present, the biggest weakness of the car starter is The magnetic strength is insufficient, and the driving force provided during startup is limited, which cannot meet the requirements of quick startup of the car. Contents of the invention [0003] The object of the present invention is to provide an automobile starter and a method for fixing the magnetic block in the stator of the starter, so as to solve the problem of insufficient magnetic strength of the existing starter and limited driving force when starting. [0004] In orde...
