[0002] The central differential lock is a locking mechanism installed on the central differential, which is used for four-wheel drive vehicles. Its function is to improve the passing ability of the vehicle on bad roads, that is, when one drive axle of the vehicle is idling, the differential can be quickly locked to make the two drive axles rigidly connected. In this way, most or even all of the torque can be transmitted to the non-slip drive axle, fully utilizing its adhesion to generate sufficient traction to enable the vehicle to continue driving.

The structure is simple, the operation is very convenient, and the detection of a large number of drive axle differential lock devices can be realized.

[0004] However, the differential lock detection device in the above still has some problems when in use, for example, the axle differential lock pressure switch requires the size of the button in the initial position, at which time the axle differential lock pressure switch terminal 1 and terminal 2 are conductive, and the button is required to be pressed to disconnect the switch terminal 1 and terminal 2, which is the key feature of the axle differential lock pressure switch, and its accuracy directly affects the performance of the product. It is required to be 100% detected in the assembly process and the inspection process and before delivery.
