Description

Starting motor isolator structure

Technical Field

The utility model relates to an isolator technical field, concretely relates to starting motor isolator structure.

Background

The one-way clutch (also called electric starting overrunning clutch) is a device for transmitting the power of an automobile engine to an axle in a switching mode. While the gasoline engine powered vehicle is running, the engine is running continuously. However, in order to meet the requirement of the running of the automobile, the vehicle must have actions such as stopping and shifting gears, so a set of mechanism must be added to the external linkage of the engine to interrupt the transmission of power according to the requirement, so as to achieve the actions of making the vehicle stationary or shifting gears under the condition that the engine is continuously operated. The group of mechanisms is a power connection device. The clutch mechanism is arranged between the engine and the manual transmission and is responsible for transmitting the power of the engine to the manual transmission. When the clutch pedal is released, the pressure plate in the flywheel tightly presses the friction plate by the force of the spring, so that the friction plate and the friction plate are linked without sliding to achieve the purpose of connection, and the power of the engine can be transmitted to the gear box through the mechanism to complete the power transmission. When the pedal is stepped on, the mechanism pressurizes the spring, so that the periphery of the spring is tilted, and the leather pressing plate is separated from the friction plate. At this time, the friction plate and the flywheel cannot be linked, and even if the engine continues to operate, power cannot be transmitted to the gearbox and the wheels, so that the driver can perform actions such as gear shifting, parking and the like without flameout of the engine. When the isolator transmits the engine, the rotating speed of the engine at the brake where the starter does not stop working is higher than that of the starter after the automobile is started, the engine can generate reverse impact force on the isolator, and most of the isolators in the market adopt a buffer structure of rollers and springs to reduce the impact force.

However, in practical use, the damage of impact force to the one-way device cannot be well weakened by the one-way device adopting the buffer structure of the roller and the spring in the market.

Therefore, it is necessary to provide a starter motor isolator structure to solve the above problems.
