The load testing device comprises a torque sensor group and a data collecting and processing device which is connected to the rear portion of torque sensors; the torque sensor group comprises at least a torque sensor; the upper portion of the torque sensor is connected with an adjustable base through a rigid connecting shaft; the adjustable base is provided with a reversed L-shaped crank arm; the front end of the crank arm is provided with a clamping fixed device which is used for clamping testing pieces; and the connecting shaft is provided with a limiting bearing and a bearing supporting seat which is used for fixing the limiting bearing at the same time. The device for measuring the swing torques of the upper joint yoke and the lower joint yoke of the intermediate transmission shaft of the automotive steering system has the advantages of being simple in technology, convenient to perform machining, easy to assemble, simple to operate and easy to maintain at the same time.
Description
Technical field
The utility model relates to the automobile parameter pick-up unit, is specially the pick-up unit that a kind of measured automobiles steering intermediate propeller shaft saves the fork shaking moment up and down.
Background technology
Automobile steering system mainly forms by turning upward axis, transmission shaft and the large parts of steering box three.The driver applies moment on bearing circle, and moment is passed to intermediate propeller shaft through turning upward axis.Be electric power-assisted steering tubular column if turn upward axis, be loaded on the assist torque sum that the moment on intermediate propeller shaft provides for driver's input torque and steering on bearing circle, and in the middle of on general minicar, this moment of transmission shaft is about 30-40Nm.
Intermediate propeller shaft has upper joint fork and lower joint fork, and when middle transmission shaft is tested, the shaking moment of upper and lower two joint forks under immunization with gD DNA vaccine should be less than respectively a certain about definite value, could meet system requirements.Intermediate propeller shaft also only has shaking moment enough little, and its moment of torsion that will turn upward axis of guarantee passes to the steering box input end expeditiously, clamping stagnation occurs in the time of also avoiding the direction of operating dish, operating physical force is overweight and turns to the phenomenon such as irregularity to occur simultaneously.Therefore, the shaking moment measurement that middle transmission shaft is saved to fork up and down seems and is even more important.
The utility model content
The technical matters that the utility model solves is to provide a kind of measured automobiles steering intermediate propeller shaft to save up and down the device of fork shaking moment, and this testing table efficiency is high, designs ingeniously, and its manufacturing cost is relatively cheap.Both can, for the online detection of intermediate propeller shaft production firm, also can carry out specialty test and test for professed machine testing laboratory.
The technical matters that the utility model solves realizes by the following technical solutions:
Measured automobiles steering intermediate propeller shaft saves the device of fork shaking moment up and down, comprise charger and load testing device, wherein, the data collection process device that load testing device comprises the torque sensor group and is connected to the torque sensor rear portion, described torque sensor group should comprise at least one torque sensor, on it, by a rigid connecting shaft, be connected on adjustable frames, " ┎ " type is installed on adjustable frames and cranks arm, and be provided with a clamping and fixing device for clamping test block at the front end of cranking arm; Simultaneously, for guaranteeing the stability of intermediate connecting shaft, also be provided with Limit Bearing on coupling shaft, and be provided with bearing support block in order to fixing Limit Bearing.
In the utility model, described data collection process device is torque detector, and connects the PC controller or be directly installed on the PC end that moment detects software at the moment detector end.
In the utility model, described bottom of cranking arm is provided with a cross slide way, make crank arm can be on adjustable frames laterally slippage, to be applicable to the joint fork of different size, make the center line of joint fork spider center and coupling shaft when work on same axis.
Beneficial effect: the utility model low cost of manufacture, simple in structure, easy care, simple to operate, perfect in shape and function, test and test efficiency are high, and data feedback is timely etc., to environment for use, requires low.And the moment test is carried out instantaneous acquiring and Drawing of Curve with PC software, with mean value and the rotating torque fluctuation of measuring rotating torque, reach the detection effect of expection.
The accompanying drawing explanation
The front view that Fig. 1 is the utility model preferred embodiment.
The vertical view that Fig. 2 is the utility model preferred embodiment.
