Description

Technical Field

[0001] The utility model relates to the technical field of gearboxes, in particular to a gas-assisted manual gearbox gear shifting protection system. Background Art

[0002] The clutch and transmission are two important components of the car's transmission system, which work together to transfer power and achieve gear shifting. The clutch is located between the engine and the transmission. Its main function is to transfer power and can shift gears when the power is disconnected. In a manual transmission car, the driver decouples the engine and transmission by pressing the clutch pedal to achieve gear shifting.

[0003] The clutch mainly includes pressure plate, friction plate, release bearing and other parts, while the gearbox is responsible for changing the speed and torque of the vehicle. It uses different gear combinations to achieve transmission ratios at different speeds. Depending on the type of car, the gearbox can be manual or automatic. Manual gearboxes require the driver to select the appropriate gear by stepping on the clutch and shifting the gear lever. At present, when driving a manual transmission vehicle on a daily basis, the driver needs to frequently select and shift gears to maintain the appropriate horsepower and speed of the vehicle during the driving process. Occasionally, the clutch pedal does not reach sufficient travel, resulting in the clutch not being completely separated and the gear shift synchronizer gear being damaged, which affects the service life of the gearbox.
