Abstract
The utility model discloses a starting motor for automobile engine, aiming at providing a permanent magnetic starting motor with low rotation speed, big torque and small volume and comprising a front cover, a starter, a stator and an armature. A planet gear reducer is also arranged inside the motor. The length of the armature shaft is shortened and a part of shortened armature shaft serves as an output shaft of a rotating arm of the planet gear mechanism. The inside of the motor, after the speed reduction by the planet gear, changes the output characters of the motor, thereby meeting with the requirements for the start-up of ''low rotate speed, big torque and small volume'' and the installation. The utility model can not only meet the start-up requirements of the automobile engine with big start-up load, but also meet the installation requirements of the engine with a limited space, which is particularly suitable for being used as a start motor of an engine on a small size vehicle.
Description
Affiliated technical field
The utility model relates to a kind of automobile starting motor, especially a kind of magneto actuating motor.
Background technology
At present, the automobile engine actuating motor is a direct current machine, is divided into excitation-type actuating motor and magneto actuating motor two classes from magnetic approach.When this two classes motor was directly exported by isolator by armature (rotor), latter's output speed height, moment were less; Be equal under the situation at both rated power, latter's more compact structure, volume are littler.Yet, automobile engine adopts a plurality of housing structures usually, its starting load is bigger, directly can not satisfy the engine start requirement usually by armature by isolator output speed height, magneto actuating motor that moment is little, when enough, adopt the excitation-type actuating motor that output speed is low, moment is big between engine air more.
Development along with China's automobile industry, enhancing as vehicle functions such as the star CM minicar in Chang'an, golden cup commercial vehicle, the Big Dipper minicar, Mondeo cars, its complete vehicle structure is arranged compact more, the automobile engine occupation space is more limited, and the excitation-type actuating motor that volume is bigger just can not satisfy installation requirement.
The utility model content
In order to overcome existing magneto actuating motor output speed height, the big burden requirement of moment starting little, that can not satisfy automobile engine, and excitation-type actuating motor volume is big, the deficiency that can not satisfy the requirements of installation space of limited engine, and technical problem to be solved in the utility model provides that a kind of not only output speed is low, moment big but also the less magneto actuating motor of its volume.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of automobile engine actuating motor, comprise protecgulum, isolator, stator, armature, it is characterized in that: be provided with the planetary gear deceleration device between the armature core of described isolator and armature.
Described planetary gear deceleration device has the pivoted arm output shaft of the internal gear (centre wheel) of a main body, a main body, two to four planetary gears, described two to four planetary gears are sleeved on two to four uniform planet wheel spindles on the pivoted arm output shaft disk, and the pivoted arm output shaft passes the center of internal gear.
Two to four planetary gears form uniform state in the such scheme, make the inner stress balance of planetary gear deceleration device, the rotating speed of the armature of motor slows down by the planetary gear deceleration device, export indirectly by the isolator on the suit pivoted arm output shaft, change the output characteristic of motor, thereby obtain the automobile engine actuating motor that a kind of output speed is low, moment is big.
The beneficial effects of the utility model are that not only rotating speed is low for motor, moment is big, and its volume is less.Do not change the motor external shape, do not lose power of motor (ignoring transmission loss), make the magneto actuating motor when keeping the less advantage of volume, reach the output characteristic of excitation-type actuating motor, finally reach and to satisfy the installation requirement that engine takies the confined space, can satisfy the start request of the big load of automobile engine again.The utility model is especially suitable for use as the actuating motor in compact car.
