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 is only in one direction, front and rear, and cannot test the manipulation force in the left and right directions of the upper space of the joystick, let alone the angular displacement of the corresponding joystick. It cannot meet the new and higher detection requirements for the shifting performance of the vehicle manual shift transmission system; and the shape of the handle is different from the handle of the actual vehicle joystick, and the driver's grip does not conform to the actual manipulation of the human body. The control and manipulation force is different when the tester is not installed; this utility model is installed and fixed by clamping the joystick of the vehicle under test, and the adjustment and positioning of the height direction is not convenient enough, so the application range of this technology is greatly limited

A device for testing control force on vehicle shift lever and corresponding shift comprises control elver seat, a control force sensor, tilt angle shift sensor and a control lever connected in the following way; the control force sensor is fixed at the outer thread of the control lever seat by its internal thread and nut, the tilt angle shift sensor is fixed on the control lever saet by screws, and the control lever is fixedly connected with the control lever seat by screws, and the control lever is fixedly connected with the sensing part of the control ofrce sensor directly. The control lever seat and sensors fixed on it are sleeved on the gearshift control lever and fixed by screws which can simultaneously and synchronously test two directions of control force and tilt angles and striking angle shift between control force and corresponding control lever or control rod.
Description
technical field [0001] The invention relates to a test device on a vehicle transmission control lever, in particular to a test device for the control force on the vehicle transmission control lever and the corresponding control lever angular displacement, and belongs to the field of vehicle detection in mechanical engineering. Background technique [0002] The vehicle manual shift transmission system includes the shift control handle, also known as the joystick, the gearbox, the linkage between the joystick and the gearbox; the detection of the operating force of the vehicle shift change handle with a spherical hinge at the fixed end and the handle The corresponding spatial angular displacement is a new requirement for testing the shifting performance of the vehicle manual shifting transmission system. Through synchronous continuous dynamics, it is detected that the driver is in the driving state of the vehicle, during the shifting process, the front and rear, left and right ...
