Description

Technical Field

[0001] The utility model belongs to the technical field of starters, and in particular relates to a side-mounted starter with a sealing structure and taking into account both idle start-stop and higher power. Background Art

[0002] Existing automotive starters are mostly installed with a stopper. When the rear end space of the starter is small and the disassembly is poor, a side installation type is used, as shown in the attached figure. Figure 1 , through lateral disassembly and assembly, the space required at the rear end of the starter is reduced. However, due to the sealing requirement at the transmission end, this installation form requires the front cover of the starter to be pasted with sealing material, the front cover is enlarged, and a larger area plane is required on the transmission side for sealing. At the same time, installation space needs to be reserved for the front cover;

[0003] Some car manufacturers have different idle start-stop and minimum starting temperature requirements, different starter shapes, and different installation interfaces. Summary of the invention

[0004] The utility model aims to provide a side-mounted starter with a sealing structure that takes into account both idle start-stop and higher power, so as to solve the problem that when the N20TD high-efficiency engine platform is arranged, the rear end disassembly space of the starter is insufficient, and the starter cannot be installed in a stoppered manner, but because the flange of the matching transmission front casing is enlarged and close to the cylinder body, the conventional side-mounted starter cannot seal the flywheel housing (used to connect the cylinder body and the transmission), and the requirements of different car manufacturers and models for idle start-stop and minimum starting temperature are different, and a unified interface is required.

[0005] The technical solution adopted by the utility model is:

[0006] A side-mounted starter with a sealing structure that takes into account both idle start-stop and higher power, comprising a starter body, wherein the starter body is mounted on the engine intake side and on the engine cylinder flange, and the starter body is mounted on the side, the front end cover of the starter body adopts a stepped structure, and a sealing strip is pasted on the front end cover to seal the flywheel housing.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] The utility model arranges the starter body on the intake side of the engine, on the cylinder flange, and is installed sideways. The front end cover of the starter body adopts a stepped structure, and the interfaces of the idle start-stop state and the high-power state schemes are unified.

[0009] The utility model reduces the space at the rear end of the starter required for disassembling the starter by side-mounting and raising the sealing cover at the front end of the starter, so that the flywheel housing can be sealed when the flange of the front casing of the transmission is enlarged and closer to the cylinder body, thereby meeting the dust and water proofing requirements of the car factory; only the internal components of the starter are changed or the length of the stator and rotor of the starter is increased to realize the idle start-stop and high-power functions, meet the needs of more vehicle development projects, unify the installation interface, and reduce the status of starter related parts.

[0010] The utility model can be arranged on the N20TD high-efficiency engine project, can avoid the suspension to the maximum extent, and reduce the risk of tearing of the aluminum cylinder body. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0017] like Figure 3 As shown, the engine block 2 is close to the transmission 5 and is connected by a flywheel housing 4 . The engine is right-suspended and arranged between the second and third cylinders of the engine block 2 .

[0018] like Figure 2~Figure 4 As shown, the utility model is a side-mounted starter with a sealing structure that takes into account both idle start-stop and higher power, comprising a starter body 1,

[0019] The starter body 1 is installed on the intake side of the engine and on the flange of the engine cylinder block 2, and the starter body 1 is installed sideways. The starter body 1 is positioned and installed on the engine cylinder block 2 using two positioning sleeves, which reduces the space requirement for the rear end of the starter.

[0020] The front end cover 6 of the starter body 1 adopts a stepped structure, and the front end cover 6 is pasted with a sealing strip 3 to seal the flywheel housing 4. At the same time, the requirements for the plane sealing area and installation space of the flywheel housing 4 are reduced, such as Figure 2 , Figure 4 As shown;

[0021] By increasing the life of the starter's internal components and lengthening the stator and rotor lengths of the starter body 1, the starter's durable starting times are increased from 45,000 times to 250,000 times, increasing the starter's power while keeping the starter's installation interface unchanged.

[0022] The stator and rotor lengths of the starter body 1 are 90 mm to 95 mm, preferably 91 mm.
