Detailed description of the invention
Hereinafter describing detailed features and the advantage of the present invention the most in detail, its content be enough to make any
Skilled in the art realises that the technology contents of the present invention and implement according to this, and according to the description disclosed by this specification,
Claim and accompanying drawing, skilled person readily understands that purpose and advantage that the present invention is correlated with.
As it was previously stated, in the prior art, it is the most all to use wireless mode that the parameter within vehicular transmission shaft is carried out
Measure, which results in and measure cost height, measurement apparatus complexity and the knowledge expertise of technical staff is required the shortcomings such as high.
It addition, when measuring transmission shaft sheath internal grease temperature, it will usually run into following problem.
Problem one: within the confined space that transmission shaft sheath internal grease is in dust cover sheath and power transmission shaft is surrounded,
K-type thermocouple directly directly cannot be contacted with tested oils and fats, thus oils and fats temperature cannot be measured.
Problem two: power transmission shaft is the parts of a relative vehicle body high speed rotating, measures sensor and the power transmission shaft of temperature
Directly contact and be fixed on above power transmission shaft；And data acquisition equipment is integrally fixed at interior, relative vehicle body is static.
Therefore, how the K-type temperature sensor of rotation and static data acquisition equipment being coupled together also is a challenge.
Problem three: axle head slip ring is to need to fix and coaxial in hub for vehicle wheel, how to be fixed and coaxial at wheel
Above wheel hub, this most individual problem.
The invention provides a kind of based on contact K-type thermocouple, the new thermometry of axle head slip ring, use pure
The mode of pure mechanical connection measures the oils and fats temperature being in inside vehicular transmission shaft under sealing state, solves well
Shortcoming that wireless measurement is brought and mentioned above three problems.
