Embodiment 1

[0061] In this embodiment, a flow control valve is provided. The flow control valve adopts a plurality of high-speed on-off valves arranged in parallel to form an array structure. Through the on-off control of the high-speed on-off valve, a wide range of adjustment and control of the flow rate of the flow control valve can be realized. control; more importantly, through the integrated design of multiple high-speed on-off valves on one valve structure, the flow control of the flow control valve can be realized more simply, and the miniaturization of the overall structure of the flow control valve has been fully realized. While controlling the valve flow and controlling precision, the control valve has better performance.

[0062] refer to figure 1 and figure 2 , the flow control valve 100 in this embodiment includes:

[0063] Valve body assembly, the valve body assembly includes a main valve body 102, the main valve body 102 is provided with a plurality of installation parts...

Embodiment 2

[0080] This embodiment is a vehicle suspension shock absorber assembly, the vehicle suspension shock absorber assembly includes a shock absorber, the shock absorber is provided with a flow control valve, and the flow rate of the flow control valve is controlled to Adjust the damping force of the shock absorber. The flow control valve in Embodiment 1 is used to adjust and control the oil flow in a large range and with high precision through the flow control valve, so as to realize the adjustment and control of the damping force of the shock absorber; based on the flow control valve’s With the above performance, the shock absorber using the flow control valve has great progress and advantages compared with the prior art in terms of the adjustment range and control accuracy of the damping force. The following is a further description in conjunction with its specific structure:

[0081] refer to Figure 8 and Figure 9 , the shock absorber in this embodiment includes a cylinder...

Embodiment 3

[0092] This embodiment is a vehicle suspension system, which includes the vehicle suspension shock absorber assembly in the above embodiments, and the vehicle suspension shock absorber assembly is respectively arranged at positions corresponding to the front wheels and the rear wheels of the vehicle. Based on the performance of the vehicle suspension shock absorber assembly that adopts flow control control, the vehicle suspension system using the vehicle suspension shock absorber assembly has very good comprehensive performance and can well improve the comfort of the car and safety, it can meet the high-performance and high-quality requirements of the vehicle suspension system.

Abstract

The invention relates to the technical field of valves, and discloses a flow control valve, a vehicle suspension shock absorber assembly and a vehicle suspension system. The flow control valve comprises a valve body assembly and multiple high-speed switch valves; the valve body assembly comprises a main valve body, multiple mounting parts are arranged on the main valve body, oil inlet holes and oil outlet holes which communicate with the interiors of the mounting parts are formed in the positions, located on the mounting parts, of the main valve body correspondingly, and the oil inlet holes communicate with the corresponding oil outlet holes to form multiple oil channels arranged in parallel; the high-speed switch valves are arranged in the mounting parts respectively and are in sealing fit with the mounting parts, and the on-off states of the oil channels are controlled by controlling opening and closing of the high-speed switch valves. The flow control valve has the characteristics of being large in flow adjusting range, high in response speed and high in flow control precision, and can be applied to different working conditions.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a flow control valve, a vehicle suspension shock absorber assembly and a vehicle suspension system. Background technique [0002] The high-speed on-off valve has the advantages of small size, low cost, insensitivity to pollution, etc., and has a high response speed, which can realize digital control by computer. It is widely used in the field of hydraulic control and is an important direction for the development of hydraulic technology. [0003] At present, most of the vehicle suspension systems on the market are passive double-tube hydraulic shock absorbers, which have fixed characteristics and provide fixed damping characteristic curves in the tension and compression strokes. Therefore, in the adjustment of the dynamic characteristics of the whole vehicle, only A compromise between ride comfort and handling stability cannot be found, which cannot satisfy the best match of vehicl...
