A rotary damping buffer tooth-mesh automobile motor

Abstract

The invention discloses a rotary damping buffering meshed type automobile motor, aiming to solve the problems of easy gear milling and complicated structure of the existing motor. The automobile motor disclosed by the invention comprises a driving device, an electromagnetic switch and an electric driver and the like, wherein the driving device comprises a pusher dog, a one-way device spring, a round iron plate, a one-way clutch and a return hairspring; and the electromagnetic switch also comprises a spring, a movable tactile disk, a tactile point, a tactile rod, a tactile rod return spring and a holding electromagnetic coil. According to the invention, a backspring is used and the principle that the backspring becomes more and more tight along with screwing due to the reverse acting force is also used to form a buffering and fastening machine element, thus the meshing can be realized fully and lightly without damaging gear rings and producing gear milling. By adopting the motor disclosed by the invention, the cost can be reduced, partial motor cast iron components can be saved, the weight can be lightened and the energy-saving effect can be more obvious; as the lever mechanism of the traditional motor can be omitted, the size can be reduced, the structure can be more compact, the materials can be saved and the motor is lighter and smaller; and besides, the product has excellent performance, extremely low failure rate, faster startup and no rigid frictions, thus the service life of the motor gear rings can be prolonged. Therefore, the motor disclosed by the invention can be used for replacing any existing starting motor in the market.

Description

Technical field [0001] The invention relates to an automobile accessory, more specifically an automobile motor. Background technique [0002] Existing automobile starter motors are mainly divided into three categories, namely geared motors, forced toothed motors, and flexible toothed motors. The so-called deceleration motor is equipped with a deceleration system, which can reduce the speed of the gear to achieve the purpose of speed reduction and torque increase. At the same time, it is small in size, light in weight and low in cost. It should be said that the deceleration starter is a trend, but the deceleration starter has many technical difficulties, such as cumbersome production, easy wear and tear of the star wheel and other parts, resulting in slipping, and it cannot be guaranteed to be fully meshed every time. The so-called forced meshing motor is a forced meshing starter. After the starter is energized, the electromagnetic switch works, and the gear is driven to mov...

Problems solved by technology

Otherwise, the following adverse consequences will occur: First, the gears are not meshed, and the electromagnetic switch contacts are connected, resulting in tooth milling; second, the gears are just meshed, and the electromagnetic switch contacts are connected, resulting in the teeth being interrupted
