Abstract
The invention discloses a force-sensing steering gear gimbal, which belongs to the technical field of electromechanical actuator system and is characterized by comprising a movable gimbal, a bearing capable of withstanding both axial force and radial force, a pedestal and a strain measuring bridge, wherein one end of the movable gimbal is connected with a steering gear to be tested while the other end thereof is fixedly connected with an inner ring of the bearing capable of withstanding both axial force and radial force, an outer ring of the bearing is fixedly connected with the pedestal, and the movable gimbal can rotate within 360 degrees; the strain measuring bridge is affixed to the root of the pedestal, the load of the steering gear to be tested which is connected with the movable gimbal is transferred to the pedestal through the movable gimbal and the bearing, the strain measuring bridge generates an output corresponding to the strain of the pedestal, and the polarity and the size of the output represent direction and size of the load of the steering gear to be tested respectively.
Description
Technical field
The steering wheel gimbals of band power sense belong to motor-driven actuator system technical field.
Background technology
The steering wheel test macro is made up of load loader, steering wheel support, force cell, test computer etc. usually, and common tested steering wheel one end peace is connected on the steering wheel support, and the other end links to each other with loader by force cell.Its shortcoming of said method is that force cell is followed the motion of steering wheel output block, and inconvenience is used in force transducer power supply and the also accompany movement of signal output cable, because the quality of force transducer self also can be brought extra inertial force when accelerated motion takes place.
Summary of the invention
The object of the present invention is to provide a kind of steering wheel gimbals, can save the force cell between the load loader and steering wheel in the steering wheel test macro with the dynamometry function.
The invention is characterized in and contain: movable gimbals, can bear bearing, base, strain-measuring bridge that axial force again can bearing radial force, wherein:
Described movable gimbals one end links to each other with tested steering wheel, the other end and describedly can bear the bearing inner race that axial force again can bearing radial force and connect firmly, and described bearing outer ring and base connect firmly, and described movable gimbals can rotate by 360 degree; Tested steering wheel is connected on the described movable gimbals, then tested steering wheel load by described movable gimbals, can bear the bearing that axial force again can bearing radial force and be delivered on the described base described base generation strain;
Strain-measuring bridge sticks on described base root, and its polarity of the output of strain bridge and size are represented tested steering wheel loading direction and size respectively.
Because the movable gimbals of the steering wheel of above-mentioned band power sense can rotate by 360 degree, the steering wheel testing requirement that can adapt to different setting angles, strain-measuring bridge and base connect firmly simultaneously, no-movable part, therefore the steering wheel gimbals of above-mentioned band power sense have simple in structure, adaptability is strong, advantage such as easy to use.
The invention will be further described below in conjunction with drawings and embodiments.
