Lockable damping control shock absorption system

Abstract

The invention relates to a lockable damping control shock absorption system, which comprises a hydraulic cylinder and an oil storage cylinder. The hydraulic cylinder comprises a cylinder sleeve, a piston and a piston rod; the piston is glidingly arranged in the cylinder sleeve; two ends of the cylinder sleeve of the hydraulic cylinder are sealed by using first and second valve blocks; one end of the piston rod is connected with the piston, while the other end passes through the second valve block; and the cylinder sleeve is divided into first and second cylinder areas by the piston, the firstand second cylinder areas are connected with the first and second valve blocks respectively, the first cylinder area is communicated with the oil storage cylinder through the first valve block, the oil storage cylinder is communicated with the second valve block through an electromagnetic valve, and the second valve block is communicated with the second cylinder area. The lockable damping controlshock absorption system has the advantages of skilful design, compact structure, low machining and manufacturing difficulty, reduced production cost, convenient maintenance, reliable performance, free maintenance in normal use, implementation of damping locking control, good shock absorption effect and stable operation, is not easy to cause the locking phenomenon, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of damping and shock absorbing control systems for vehicles, in particular to the technical field of hydraulic damping and shock absorbing control systems for vehicles, and specifically refers to a lockable damping control shock absorbing system. Background technique [0002] With the rapid development of my country's automobile manufacturing industry, various vehicle manufacturing industries are also advancing by leaps and bounds, but the key technologies of many systems are still monopolized by foreign technologies. At present, the damping and shock absorption systems used in domestic vehicles generally use mechanical control systems. This kind of mechanical control damping system is generally composed of executive components (such as hydraulic cylinders), hydraulic control devices (such as fuel tanks, oil pipes and oil circuit control components), circuit signal acquisition and transmission devices, and sys...

Problems solved by technology

[0003] The disadvantages are: 1. The system structure is complex and the installation space utilization rate is low; 2. The system integration is poor, the price is high, and maintenance is frequent and difficult; at the same time, due to the many connection points and exposure, the hydraulic oil runs, leaks, and seeps seriously; 3. , Limited by the damping adjustment range, the shock absorber is prone to lock when the vehicle is running at high speed or under heavy load
