The invention discloses a drive suspension device of an automatic driving test vehicle. It includes a support, a motor, a swing arm, a shock absorber, a driving wheel, a main synchronous pulley, a slave synchronous pulley and a synchronous belt. The support is provided with a vertically arranged first through slot and a second through slot side by side. The top of the swing arm is located in the first slot and is hinged to the support through the first rotating shaft. The shaft extension of the motor passes through the side wall of the support horizontally and extends into the second slot. The main synchronous pulley is sleeved on the shaft extension of the motor. The shaft extension of the motor is coaxial with the first rotating shaft, the driving wheel is hinged with the bottom end of the swing arm through the second rotating shaft, the slave synchronous pulley is sleeved on the second rotating shaft, the main synchronous pulley and the slave synchronous pulley are connected by a synchronous belt, The middle part of the swing arm is provided with a first through hole, the bottom end of the shock absorber extends into the first through hole and is fixedly connected with the lower part of the inner wall of the first through hole, the top end of the shock absorber extends into the first through groove and passes through the third rotating shaft and the support hinged. The invention is designed as a first-stage synchronous belt transmission, with high transmission efficiency, and the synchronous belt pulley is not easy to loosen and fall off.
Description
technical field [0001] The invention relates to the technical field of suspension, in particular to a drive suspension device for an automatic driving test vehicle. Background technique [0002] With the rapid development of computer technology and artificial intelligence technology in recent years, unmanned driving technology is one of the hot technologies being developed by all parties. Before automakers launch commercial self-driving cars, a variety of tests must be conducted to ensure that self-driving cars are safe on the road. In order to test the safety and reliability of unmanned vehicles, it is necessary to simulate the traffic conditions in the test field, so that the test road conditions are basically consistent with the real road conditions, such as simulating the driving environment of pedestrians, non-motor vehicles and motor vehicles under various road conditions . [0003] In order to ensure the safety of the test and prevent the vehicles under test from be...
