Problems solved by technology

Although this utility model can test the vehicle parking brake control force and the hand pull force of other joysticks, it cannot test the corresponding spatial angular displacement of the joystick, so it cannot meet the new and higher detection requirements for the maneuverability of the vehicle joystick; and The shape of the handle is different from the handle of the actual vehicle joystick, and the driver's grip posture does not conform to the actual manipulation of the human body, so the measured value is different from the control manipulation force when the tester is not installed; The method of measuring the vehicle joystick is installed and fixed, and the adjustment and positioning of the height direction is not convenient enough, so the application range of this technology is greatly limited

Abstract

A test device for testing control force on the control lever and corresponding shift comprises control level saet, a control force sensor, tilt angle shift sensor, control level and connecting rod connected in the following way: the control force sensor and corresponding tilt angle shift sensor are fixed at both sides of the control lever seat by screws the control lever fixedly connected with the sensitive part of the control force sensor by screws when testing, the control level seat and the sensor fixed on it are sleeved on the tested control level and fixed by screws.

Description

technical field [0001] The invention relates to a testing device on a joystick, in particular to a testing device for a manipulation force on a joystick and a corresponding angular displacement of the joystick, and belongs to the field of vehicle detection in mechanical engineering. Background technique [0002] The push-pull manipulation force and the corresponding angular displacement of the joystick of the vehicle or some construction machinery are new requirements for the detection of the manipulation performance of the manipulation mechanism. Through synchronous continuous dynamic detection of the driver's push-pull manipulation force and The corresponding relationship of the angular displacement of the joystick is used to judge the correctness of the design of the manipulation mechanism, the quality of assembly, and the wear and tear of the system. At present, an S-shaped resistance strain pull pressure sensor or a beam-type resistance strain hand pull force sensor and...
