Example Embodiment

[0060] Example one

[0061] In this embodiment, a flow control valve is provided, and the flow control valve consists of a plurality of parallel set of high-speed switch valve, by controlling the flow control valve flow, a wide range of regulatory regulators of flow control valve. Control; more important is to make the flow control valve flow control more simple by using a plurality of high speed switch valves in a valve structure, and fully realize the integral structure of the flow control valve, in the guarantee control The valve flow control and control accuracy make the control valve have better usage performance.

[0062] Refer figure 1 and figure 2 The flow control valve 100 in this embodiment includes:

[0063] The valve body assembly includes a main valve body 102, and a plurality of mounting portions 121 are provided on the main valve body 102, and the main valve body 102 is located in the position of the mounting portion. The inlet hole 122 and the oil hole 123, the oil...

Example Embodiment

[0079] Example 2

[0080] This embodiment is a vehicle suspension damper assembly, which includes a damper, and a flow control valve is provided on which a flow control valve is provided by controlling the flow rate of the flow control valve. Adjust the damping force size of the damper. With the flow control valve in the first embodiment, the adjustment and control of the damping force size of the damper damping force is achieved by the flow control valve, and the high-precision adjustment and control of the oil flow; the flow control valve is obtained. The above properties have great progress and advantages over the prior art in the regulation range and control accuracy of the damping force. Further descriptions are further explained below in conjunction with the specific structure:

[0081] Refer Figure 8 and Figure 9 In this embodiment, the damper includes a cylinder assembly, a flow control valve, and a bottom valve assembly 204 disposed within the cylinder assembly 204, a pis...

Example Embodiment

[0091] Example three

[0092] This embodiment is a vehicle suspension system comprising a vehicle suspension damper assembly in the above embodiment, the vehicle suspension damper assembly, respectively, in a position of the vehicle front wheel, the rear wheel corresponding to the vehicle. Based on the performance of the vehicle suspension damper assembly with flow control control, the vehicle suspension system using the vehicle suspension damper has a good comprehensive performance, and it is possible to improve the comfort of the car. And safety, can meet the high performance and high quality requirements of the 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...
