Problems solved by technology

[0004] However, the existing valve control system has the following problems: 1) The experimental verification using the clutch engagement test bench needs to simulate a variety of complex working conditions. clutch equipment damage
2) When the transmission equipment is running, emergency braking will cause torque overload to the clutch, causing irreversible damage to the clutch and transmission equipment
3) Most of the benches are equipped with inertia blocks to simulate the load of actual working conditions. When the motor stops and starts suddenly, or the speed and speed gears do not match, it will cause the relative inertia force between the inertia block and the transmission equipment, resulting in a large load

Embodiment 1

[0034] In this example, if figure 1 As shown, a wet clutch overload protection and piston stroke adaptive control system is provided, which includes an oil pipeline part, a control execution part, a sensor part, and a signal collection and control decision part; wherein, the oil pipeline part and the control execution part Part of the valve control system. The oil pipeline part provides sufficient oil for the control execution part, the control execution part is connected with the clutch 1, and the control execution part is connected by the signal collection and control decision-making part, and its work is controlled by the signal collection and control decision-making part. The signal collection and control decision-making part is used to receive the acquisition signal transmitted by the sensor part, and then transmit the control instruction to the control execution part.

[0035] In a preferred embodiment, the oil pipeline includes a hydraulic pump 2 , a hydraulic cylinder...

Embodiment 2

[0040] Based on the control system in the above-mentioned embodiment 1, a control method for a reversing valve and a high-speed switching valve is provided in this embodiment, which includes:

[0041] For the reversing valve 7: the reversing valve 7 receives the reversing command issued by the bench computer 11, realizes the switching of the three action positions of the reversing valve 7, and then controls the three working states of the whole system.

[0042] The first action position: it is the normally closed state of the reversing valve 7 . The normally closed state of the reversing valve 7 is used when the clutch engages and separates. When the stand (i.e., the clutch mechanical system) is in the closed state, the entire system is in a closed circuit, and the reversing valve 7 is in the normally closed valve position; the same, When the gantry is in stable operation and clutch 1 does not need any disengagement and engagement action, the oil pressure of the oil cylinder i...

Embodiment 3

[0048] Based on the control system in the above-mentioned embodiment 1, this embodiment provides a wet clutch overload protection and piston stroke adaptive control method, which can effectively protect the safety of the bench equipment and have more reasonable and intelligent adaptive functions. The control method includes four parts: emergency brake overload protection, emergency stop and sudden turn overload protection, emergency treatment protection and self-adaptive regulation. in:

[0049] 1) Emergency brake overload protection: the bench computer 11 receives the real-time dynamic speed data signal from the speed sensor 15 on the brake disc; when the brake device brakes in an emergency, the brake disc is locked, and its speed is quickly reduced to zero . The bench computer 11 can quickly judge the locked state of the brake disc. The locked condition can be regarded as meeting the overload condition, and the bench has an overload action. At this time, the bench computer ...

Description

technical field [0001] The invention relates to the field of mechanical transmission oil circuit control, in particular to a wet clutch overload protection and piston stroke self-adaptive control system and method. Background technique [0002] Clutch is a common component in mechanical transmission, which can separate and engage the transmission system at any time, and transmit torque through the friction effect between the active part and the driven part. The friction effect mainly depends on the friction factor of the friction material and the compression force of the compression spring, both of which change dynamically during the clutch working process, and the spring compression force can be controlled by controlling the oil pressure of the clutch working cylinder. Reasonable control of the oil pressure can effectively prevent the clutch from generating too much friction work and impact during the gear shifting process, thereby improving the stability of the gear shifti...
