Problems solved by technology
When the vehicle is running on an uneven road, this structure may cause the wheels to deviate relative to the direction perpendicular to the ground, resulting in eccentric wear of the wheels
Reduce the force bearing area of the wheel and affect the grip
Figure 1B Although the left and right wheels are independently driven, the connection method of the suspension system does not distinguish between the left and right, and the axis level of each wheel cannot be guaranteed.
Especially when the height of the road surface corresponding to the left and right wheels is different, it will cause the overall vehicle body to be skewed

The embodiment of the invention discloses a suspension system and an unmanned vehicle. According to one specific embodiment, the suspension system comprises a rack fixedly connected with a vehicle body; the left wheel mechanism and the right wheel mechanism are symmetrically installed on the two sides of the rack and used for fixing a left wheel and a right wheel respectively; each of the left wheel mechanism and the right wheel mechanism comprises a connecting frame and at least two connecting rods, the connecting frames are fixedly connected with the wheels, one end of each connecting rod in the at least two connecting rods is hinged to the connecting frame, and the other end of each connecting rod is hinged to the rack; the left wheel mechanism and the right wheel mechanism can swing in the direction perpendicular to the ground relative to the machine frame under the limiting effect of the connecting rod. The embodiment is related to an unmanned vehicle, a novel suspension system is provided, and a left wheel mechanism and a right wheel mechanism are independently connected with a rack. When the vehicle is on a rugged road surface, the horizontal movement of the axes of the wheels can be ensured through the limiting effect of the connecting rods. Therefore, the running stability and road holding of the vehicle are improved, and the measurement accuracy of the odometer is ensured.
Description
technical field [0001] The embodiments of the present disclosure relate to the technical field of unmanned vehicles, and in particular, to a suspension system and an unmanned vehicle. Background technique [0002] Suspension system is a general term for all force-transmitting connection devices between the frame of the car and the axle or wheels. Its function is to transmit the force and moment acting between the wheel and the frame, and to buffer the impact force transmitted to the frame or the body by the uneven road, and attenuate the vibration caused by it, so as to ensure the smooth running of the car. [0003] In the prior art, the suspension system usually adopts Figure 1A or Figure 1B structure shown in . Figure 1A The suspension system in the model adopts a rocker arm structure. When the vehicle travels on uneven road surfaces, this structure may cause the wheels to shift relative to the direction perpendicular to the ground, resulting in eccentric wheel wear. ...
