The invention relates to the technical field of commercial vehicles, in particular to a
saddle capable of automatically adjusting a main suspension gap for an electric
tractor. Through cooperation of the front-back displacement mechanism, the sliding rail, the sliding plate, the toothed plate, the VCU
vehicle control unit, the CAN / Lin communication network unit and the main suspension distance sensor, the effect of automatically adjusting the main suspension gap is achieved, the main suspension distance sensor monitors gap data between main suspension bodies in real time, the gap data are transmitted to the VCU
vehicle control unit through the CAN / Lin communication network unit, and the gap data are transmitted to the VCU
vehicle control unit through the CAN / Lin communication network unit. The VCU vehicle
control unit controls the double-shaft motor to start according to preset parameters and actual working conditions, the double-shaft motor drives the first gear to rotate, the first gear is meshed with the toothed plate to drive the sliding plate to move front and back along the sliding rail, then the
saddle body is driven to move synchronously, automatic and accurate adjustment of the main suspension gap is achieved, and the requirement for matching of different transportation working conditions and main suspension is met; driving bumping vibration is reduced, the wind resistance coefficient is reduced, and the vehicle economical efficiency is improved.
