Description

Technical Field

[0001] The utility model relates to the technical field of shift levers, in particular to a bus-type, high-life Hall shift lever. Background Art

[0002] The existing joystick conventionally uses a marble-type gear structure. The driving signal is usually a switch signal, which is used in ordinary vehicle light shifting or wiper gear switching. In such scenarios, the signal accuracy is not high and the frequency of use is low. Therefore, a marble-type gear shift structure can be used to meet the needs.

[0003] When the shift lever is used as an FNR shift handle for a loader, this scenario requires access to the CAN bus of the loader controller. Therefore, the Hall output needs to be converted into CAN output to accurately locate the gear information. The traditional marble-type gear structure (usually with a lifespan of less than 1 million times) cannot meet the high-frequency operation requirements of the loader. The loader requires a lifespan of at least 5 million times. Usually, the main cause of failure of a marble-shaped switch shifter after 1 million times is the loosening and falling of the marble gear or the failure of the switch. Utility Model Content
