Problems solved by technology
A hydraulic cylinder generally includes a cylinder, a piston, and a piston rod. One end of the piston rod is fixedly connected to the front frame, and the other end of the cylinder is fixedly connected to the rear frame. The hydraulic cylinder mainly provides damping for the vehicle to turn through hydraulic damping to prevent the vehicle from slipping. During the turning process of the vehicle, one hydraulic cylinder must be stretched and the other hydraulic cylinder will be contracted. In the prior art, the pressure is often set by the change of the force arm provided by the hydraulic cylinder articulation system, while the articulated bus During driving, when the turning reaches a certain angle, the pressure change in the hydraulic cylinder is jumpy, so the transition of the torque is often jumpy, and the damping effect on the vehicle articulation system will appear too large or too small. In severe cases, there may even be traffic accidents

The invention discloses an infinite damping shock absorption system which includes a hydraulic cylinder, an oil storage tank, an oil suction pipeline and an oil drainage pipeline between the hydraulic cylinder and the oil storage tank. The oil suction pipeline and the oil drainage pipeline are respectively provided with one-way valves, and the oil drainage pipeline is provided with a proportion valve; the infinite damping shock absorption system also includes a pressure transmitter, an angle sensor and an electronic control unit, and the electronic control unit is connected with the pressure transmitter and the angle sensor in a signal mode, carries out logic calculus according to signal values transmitted by the pressure transmitter and the angle sensor, and controls the opening of the proportional valve according to the calculated results. The logical calculus is carried out by the electronic control unit according to the changes of the pressure and the angle, and thus the proportional valve opening is controlled, so that the hydraulic cylinder can provide suitable damping force for an articulated system, and the driving security of vehicle is ensured.
Description
technical field [0001] The present invention relates to the technical field of damping and damping control systems for vehicles, in particular to the technical field of hydraulic damping and damping control systems for vehicles, and specifically refers to a stepless damping and damping system. Background technique [0002] At present, articulated buses are gradually popularized and applied in large and medium-sized cities at home and abroad as public transportation tools. Articulated buses generally consist of front and rear carriages, sheds connecting the front and rear carriages, and chassis articulation systems. Chassis articulation systems generally consist of turntable bearings, front frames , rear frame and hydraulic system, in which the hydraulic system provides damping and buffering effect to keep the vehicle as stable as possible during driving. The hydraulic buffering system is one of the main factors affecting the performance of articulated buses. [0003] The hyd...
