IEC 62196 Vehicle Drive Over Testing System for Vehicle Connectors and Plugs
System introduction:
The vehicle drive over test system is used to check whether a plug or vehicle connector shall have adequate resistance to damage from being driven over by a vehicle, unless it is provided with a cable management system which prevents the accessory from being left on the ground.
Accessories wired with the minimum size cable of a type recommended by the manufacturer shall be placed on a concrete floor in any normal position of rest. A crushing force of (5000±250) N or (11000±550) N shall be applied by a conventional automotive tire, P225/75R15 or an equivalent tire suitable for the load, mounted on a steel rim and inflated to a pressure of (2.2±0.1) bar. The wheel is to be rolled over the vehicle connector or plug at a speed of (8±2) km/h. The accessory is to be oriented in a natural resting position before applying the force in a different direction for each sample. The accessory under test shall be held or blocked in a fixed position so that it does not move substantially during the application of the applied force. In no case is the force to be applied to the projecting pins.
Applied standard:
IEC 62196-1Ed.4CDV 2020 clause 33.2 and 33.3.
Technical Parameters:
| Test Station | Single |
| Electrical Control Method | PLC intelligent integrated control, color humanized touch interface operation (computer operation is optional) |
| Drive Mode | Motor driven |
| Load Carrying | A. Crushing force (5000±250) N B. Crushing force (11000±550) |
| Roll Over Speed | (8±2)km/h |
| Roll Over Method | The linear motor module is used to drive the automotive tire to simulate the front and rear reciprocating rolling motion (to simulate the damage caused by the accidental rolling to the vehicle connector or plug during the forward or reverse moving of the car in the real scene) |
| Crushing Force Loading | using a servo motor with a worm gear reducer to apply the crushing force |
| Crushing Force Display and Adjustment | Branded force sensor is used, and the force range is 0-20000N adjustable |
| Drive Over Tire | Michelin tire (P225 / 75R15) |
| Air Pressure of Tire | (2.2±0.1) bar |
| Test Floor | A bottom plate with cement/ concrete surface, which can be equipped with a fixture |
| Function Box of Specimen | Made of aluminum alloy, it can be adjusted up and down, right and left, and easy for installing various types of specimen, combined structure, easy to be installed and fixed |
| Lifting Device | Imported guide, it allows the load to be moved up and down freely |
| Specimen Installation | Electric winch lifting and restructuring |
| Timing Counting Display | Can be display and set on the touch screen |
| Shock Absorption Method | Damping spring |
The equipment adopts the working mode of front and rear driving of the tire (the direction of rolling is driven by the positive and negative rotation of the servo motor), keeping the sample fixed, achieve the most realistic simulation of the reciprocating rolling of the automobile tire, thus effectively carrying out simulated crushing on the specimen.
