The automatic transmission piston simulation experiment device can simulate the actual working conditions of the automatic transmission piston product and test whether the piston product meets performance requirements or not.
Description
technical field [0001] The invention belongs to the technical field of simulation experiment equipment, in particular to an automatic transmission piston simulation experiment device. Background technique [0002] The automatic transmission piston plays a vital role in the automatic transmission. The piston in the automatic transmission relies on the pressure of the oil and the restoring force of the spring to reciprocate, and the oil in the oil chamber is sealed by the inner and outer sealing lips. At the present stage, the automatic transmission piston simulation experiment device cannot simulate the actual working conditions of the automatic transmission piston products, and cannot accurately test whether the piston products can meet the performance requirements. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides an automatic transmission piston simulation experiment device capable of simulating the...
