Described cylinder links to each other by the solenoid valve of tracheae with platen one side, and an end of described solenoid valve links to each other with instrument and the PLC electric cabinet of a side that is installed in the stand table, and the other end links to each other with external source of the gas through behind the air strainer.
The inboard of described L type support is installed with the sensor adjustment device, be installed with spring fixed seat in the center pit of described sensor adjustment device, one end of described spring fixed seat is close to pressure transducer, has clamped the sensor adjustment piece between the sidewall of described sensor adjustment device and the spring fixed seat.
On the described high-pressure oil pipe oil pressure gauge is installed.
Front end face one side of described platen is equipped with gauge tap.
By the control cylinder operation of PLC electric cabinet system, cylinder promotes the piston of clutch master cylinder by push rod, brake fluid in the piston compression clutch master cylinder produces the oil pressure of 2.5Mpa～3.5Mpa, the release shaft that the brake fluid of high pressure flows to the oil cylinder of tested hydraulic pressure release bearing by high-pressure oil pipe and promotes the top is made rectilinear motion, come the simulated clutch platen at the other end of release bearing with the spring of a customization, load after its compression is equal to the maximum separation power of supporting clutch pressure plate substantially, the release bearing that is ejected like this passes through the spring return, and does axially reciprocating.
In the test adjustment stage, when clutch master cylinder 3 pressurizations, the release bearing pressurized of tested hydraulic pressure release bearing 11 ejects, compression spring 12.Spring fixed seat 13 pressurizeds of spring 12 push up the compression face of pressure transducer 15 with afterbody, realize pressure survey.After tested hydraulic pressure release bearing 11 debugging are finished, can realize long-time long duration test, at this moment by sensor adjustment device 14 spring fixed seat 13 be separated with pressure transducer 15, prevent that long-time roof pressure from damaging pressure transducer 15.
Beneficial effect
The present invention relates to a kind of durability test device of hydraulic pressure release bearing, simple in structure, utilize PLC to control the action frequency of the release bearing of tested hydraulic pressure release bearing, automatically fast, can carry out endurancing to the hydraulic pressure release bearing incessantly in 24 hours, reduce manually the detection efficiency height.
