Abstract

The present invention proposes a shock absorber system for a commercial vehicle, including a single-chip microcomputer, an alarm, a pressure sensor, two displacement sensors, and a hydraulic shock absorber; the hydraulic shock absorber is a hydraulic shock absorber with variable piston rod length, including a piston rod and The first cavity, the first cavity is provided with a second cavity, the top of the first cavity is provided with a motor, the output shaft of the motor is provided with a gear, the gear is meshed with a rack, and the lower end of the rack is connected to the upper end of the piston rod. The lower end of the piston rod is inserted into the second cavity, the second connecting ring is arranged at the lower end of the second cavity, and the first connecting ring is arranged at the upper end of the first cavity; two displacement sensors are respectively arranged on the first connecting ring and the first cavity. At the joint with the second cavity, the pressure sensor is set at the easily interfered part of the hydraulic shock absorber; the pressure sensor and the displacement sensor are respectively connected to the input end of the single-chip microcomputer, and the output end of the single-chip microcomputer is respectively connected to the alarm and the motor. The system ensures the safe and efficient operation of the shock absorber.

Description

technical field [0001] The invention relates to a vehicle safety operation control system, in particular to a shock absorbing system for commercial vehicles. Background technique [0002] The shock absorber is an important part of the automobile suspension system. It is used to suppress the shock when the spring rebounds after absorbing the shock and absorb the energy of the road impact to improve the ride comfort of the car. At present, domestic and foreign automobiles generally use hydraulic shock absorbers, also called cylinder hydraulic shock absorbers. Hydraulic shock absorbers play an important role in driving safety. [0003] For existing hydraulic shock absorbers, the length of the shock absorber piston rod needs to be considered during the design process: if the piston length is small, it is easy to pull the piston out of the shock absorber housing during the road test, resulting in failure of the shock absorber; if If the piston length is large, the hydraulic oil...
