Abstract

The invention provides a transmission valve body testing device. The signal output end of an oil pressure detection module and the signal output end of a gear switch detection module are connected with the signal input ends of a controller module respectively; and the signal output ends of the controller module are correspondingly connected with the signal input end of an oil pressure ultralimit alarm module and the signal input end of a cycle index standard reaching prompting module respectively. With the transmission valve body testing device of the invention adopted, automatic testing of a valve body is realized. The controller module is connected with a storage module through a CAN bus, and the storage function of a general CAN card is utilized to store data in a testing process, and therefore, off-line analysis on the movement process of a valve core can be facilitated. The transmission valve body testing device has a manual testing function, and therefore, different testing needs can be satisfied. After testing is completed, an alarm can be given, so that a user can be prompted, and therefore, testing efficiency is higher; and test data can be saved in real time, so that off-line analysis can be facilitated.

Description

technical field

[0001] The invention relates to the technical field of transmission valve body detection of engineering vehicles, in particular to a transmission valve body testing device. Background technique

[0002] In the transmission of engineering vehicles, the on-off of the oil circuit in the valve body is the key to whether the hydraulic transmission can work normally. This will directly affect the normal operation of the vehicle transmission. When the parts in the valve body do not move smoothly, there will be a risk of gear failure or double gear engagement.

[0003] Chinese patent ZL201320848914.4 introduces a valve body test device, which controls the shift test cycle according to the start and stop buttons. When manually observing the movement of a single valve core, manual operation is required to shift gears. The invention does not meet the requirements; and the number of shift cycles needs to be judged by workers' timing, so the test is inconvenient; because...

Embodiment Construction

[0015] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0016] Such as figure 1 and figure 2 A transmission valve body testing device shown includes an oil pressure detection module, a gear switch detection module, a controller module, an oil pressure overrun alarm module, and a cycle count reminder module; the oil pressure detection module and the gear switch The signal output terminals of the detection module are respectively connected with the corresponding signal input terminals of the controller module, and the signal output terminals of the controller module are respectively connected with the signal input terminals of the oil pressure overrun alarm module and the cycle times standard reminder module. The controller module receives the signals output by the gear switch detection module and the oil pressure detection module, and analyzes and processes them. The controller module...
