Abstract
The utility model discloses a starter for a wet clutch. The starter comprises a direct current motor, a solenoid switch, a shifting fork, a stator and a rotor, wherein a support is arranged on a rotor shaft through an oil bearing in a dynamic seal mode; a gasket is arrange on a contact part of the left end of the support and an end face of the rotor; an isolator is arranged on the rotor shaft of the right end of the support; a big gasket is arranged between the support and the isolator; the isolator is fixed at a driving end cover through the shifting fork and a shifting fork pin; a rubber sealing gasket is arranged between the support and the driving end cover; two sealing ring slots are formed on the shifting fork pin which is used for fixing the shifting fork on the driving end cover; and an O-shaped sealing ring is arranged in each sealing ring slot. When the starter is assembled, the rubber sealing gasket is arranged between the support and the driving end cover, and after the stator, the rotor and other components of the starter are assembled, the motor is tightened up by two tightening screws to ensure that the support, the rubber sealing gasket and the driving end cover are pressed and sealed. The starter for the wet clutch has the characteristics of sealing performance, oil resistance and the like.
Description
Technical field
The utility model relates to automobile and designs and manufacturing technology field, specifically a kind of wet clutch starter motor with starter motor.
Background technique
In the flywheel casing of clutch between motor and gearbox of existing motor car engine, adopt screw to be fixed on the back plane of flywheel, the output shaft of clutch is exactly the input shaft of gearbox; Be divided into two kinds of dry clutch and wet clutches according to the cooling medium clutch, wherein wet clutch is to adopt fluid that gearbox is cooled off.Starter motor is installed on the flywheel casing, and its actuation gear is positioned at flywheel casing.When motor adopted wet clutch, when gearbox was worked, cooling oil can be thrown on the starter driving gear, even entered starter motor inside; When starter motor startup work a period of time, these fluid can enter on the starter armature in continuous slit from electric machine support and Driving terminal, cause starter armature to lose efficacy, affect starter motor life-span and reliability, this just requires starter motor to have the function of protection fluid, and satisfy following requirement: engine oil is dipped into the place than the high 100mm in small gear center, vertically places 2 hours, requires to enter into starter motor inside without fluid.
Summary of the invention
Goal of the invention of the present utility model is to overcome the above-mentioned deficiency of prior art and a kind of good sealing effect, wet clutch starter motor that reliability is high is provided.
The technical solution of the utility model is: comprise direct current generator, magnetic switch, shift fork, stator, rotor; Support is loaded on the rotor shaft through oil-impregnated bearing, motive sealing; Support left end and rotor end-face contacting point are provided with packing ring; On the rotor shaft of support right-hand member one-way element is housed; Be provided with large washer between support and the one-way element; One-way element is fixed in Driving terminal through shift fork, shifting fork pin; Be provided with rubber gasket between support and the Driving terminal; Be provided with two closure gasket grooves for the shifting fork pin that shift fork is fixed in Driving terminal; In the described closure gasket groove O-ring seals is housed.
Described rotor is provided with stepped part; Support is loaded on the rotor stepped part; Be provided with packing ring between support and the rotor.
Be provided with motive sealing, oil-impregnated bearing in the utility model bracket assembly bearing chamber, shifting fork pin is provided with two seal grooves, and be equipped with the O RunddichtringO, between bracket assembly and Driving terminal, be provided with rubber gasket during general assembly, after each component assembling such as starter motor stator and rotor, tighten up motor by two fastening screw trip bolts, make support, rubber gasket and Driving terminal press seal, play the function of protection fluid.
The utility model is simulated the complete machine Environmental Conditions and is added tight test conditions and prevents oil test, being about to starter driving gear upwards vertically is fixed on the grease proofing test stand, actuation gear is immersed in the oil, and give certain pressure to fluid, placed 24 hours, and disassembled motor, starter motor is inner without any fluid as a result, the anti-oil test of product meets the demands, and the applicability of product is guaranteed.The utility model increases market share and the competitive ability of product, reduces product after sale fault and expense.
