5 Try some methods
5.1 Test case
JB/T 3767-92
5.11 Tests shall be carried out in accordance with the special test conditions. 5.1.2 Tests shall be carried out in accordance with the special test conditions. All the measuring instruments and equipment shall be within the effective measurement limits. 5.2 Empty load comparison test
Run the vehicle forward and reverse for 2m, check the sealing parts, check the connection and the contact accuracy of the wheel pair. 5.3 Negative wheel test
After the no-load test, wind 35~ turns of wire at the end of the system. 6. Determine the static tension of the wire with speed, and determine the flow rate: d. Check whether the vehicle has abnormal sound and vibration. Determine the vibration rate according to the method specified in item 3768: e. Observe the winch air suspension test process, and if the lubrication oil is 8, For example, if the oil drips from the bottom of the engine body, the surface is reversed, and there is no reverse flow, which is determined as the cleaning activity of the speed controller. The lubricant in the speed controller is discharged, and then the gas is discharged from the filter. The amount of dirt collected by the cooling device is 20mm, which is the cleaning activity of the speed controller. 6 Inspection rules
61 Each vehicle must be inspected by the manufacturing inspection department before it can be issued. 6.2 Inspection is divided into some and type inspection
