Abstract

The invention relates to a vehicle inspection device and a method, and provides a device for testing the starting and shifting performance of a vehicle and a method to solve the problem that the starting and shifting performance testing of an existing transmission lacks a special detection device. The device for testing the starting and shifting performance of the vehicle comprises a transmission,a driveshaft which is connected to the output shaft of the transmission, a drive motor which is connected to the input shaft of the transmission via an electromagnetic clutch, a data acquisition processor, and an operation controller. The transmission comprises a transmission body, a shift selecting manipulator and a shifting manipulator. The shifting manipulator is provided with a force sensor.The input shaft of the transmission is provided with a rotating speed encoder and an inertia disk. The driveshaft is provided with an inertia wheel set. The electromagnetic clutch is connected to a power source via a neutral position switch. The neutral position switch is provided at a neutral light of the transmission body. The speed encoder and the force sensor are respectively and electricallyconnected to the data acquisition processor. The drive motor, the shaft selecting manipulator, and the shifting manipulator are respectively electrically connected to the operation controller.

Description

technical field [0001] The invention relates to a vehicle inspection device and method, in particular to a vehicle start-up shift performance testing device and method. Background technique [0002] With the improvement of the driver's requirements for the shifting comfort of the automobile transmission, higher requirements are also imposed on the starting shifting performance of the entire vehicle transmission. [0003] However, at this stage, there is no standard to follow the test of the gear shift performance of the transmission, and there is no special equipment for testing. The gear shift performance test of the existing vehicle transmission is performed manually by using a push-pull gauge or a force sensor; generally, the gear shifting performance of the transmission is evaluated by collecting the gear shifting force during the process of depressing the clutch and shifting the gear. Although manual testing is simple and easy to implement, it has the following problem...
