Description
Technical field
The present invention relates to a kind of torque converter, especially a kind of angle regulating device for seat of vehicle torsional performance test board torque converter that is used for.
Background technology
At present, angle regulating device for seat of vehicle torsional performance test board is made of parts such as motor, reductor, torque sensor, signal recorder, automotive seat, frock clamps.Its detection method is torque sensor one to be brought out axle connect with seat angle adjustor by special-purpose jaw, torque sensor other end shaft connects with reductor by shaft coupling, signal wire is connected with signal recorder on the torque sensor, reductor and motor are monoblock type, torque sensor, reductor, motor are fixed on the workbench, the center absolute altitude during with the seat initial position recliner center consistent.During direct motor drive, recliner is rotated load torque and is exported to signal recorder demonstration numerical value by sensor signal.Because the angle regulating device for seat of vehicle center changes around a fixed point when rotating, central point will produce the eccentric throw of a variation, torque sensor is subjected to the eccentric moment effect, and the signal of sensor output has an additional torque, and numerical value that signal recorder shows and actual torque numeric ratio are than distortion.
Summary of the invention
The present invention will provide a kind of eccentric moment converter, and this converter can be eliminated the eccentric moment that recliner produces when rotating, and being transferred to sensor is single moment of torsion, and the data of detection are conformed to actual value.
For achieving the above object, technical scheme of the present invention is: a kind of eccentric moment converter, comprise fork head type free end bulb joint and stiff end sphere joint, be characterized in: fork head type free end bulb joint, sentence 180 ° of directions at its bulb joint maximum gauge and be provided with a tapped through hole, stiff end sphere joint is provided with the spill sphere in its joint, end, and the sphere in spill sphere and fork head type free end bulb joint matches, the gabarit in joint, end is provided with two kidney slots in 180 ° of directions, the bulb in free end bulb joint inserts the spill sphere in stiff end sphere joint, two kidney slots of tapped through hole secured in alignment end sphere, place the bearing pin in the threaded hole that is screwed into the bulb joint in the kidney slot, the slightly larger in diameter of kidney slot is in the diameter of bearing pin.
The bulb joint has a jaw in its spindle nose end, directly inserts seat gaily decorated basket jaw through jaw and is attached thereto;
The length of kidney slot is determined according to the eccentric distance of bulb joint swing;
The opposite side in stiff end sphere joint connects with little axle, on the little axle pair of bearings is installed, its shaft brings out axle by shaft coupling and torque sensor one and links to each other, torque sensor one brings out axle and is connected with band reductor drive motor by shaft coupling, and the moment of torsion of output is input in the signal recorder by the torque sensor signal line.
The invention has the beneficial effects as follows: the mounting or dismounting of this eccentric moment converter are easy, the eccentric throw that seat angle adjustor when work produces can be eliminated by eccentric moment converter, can compensate the seat angle adjustor center fully and connect level and vertical eccentric distance between the stress point center line with the torque sensor center.Making the moment of torsion of seat angle adjustor output is pure torsion.
This eccentric moment converter, simple installation connects reliably the accuracy of detection height.
The angle regulating device for seat of vehicle torsional performance that this eccentric moment converter can adapt to all kinds, all size detects.
