Technical field
The present invention relates to a kind of damping unit, a kind of damping unit of performance test of automobile gear shift assembly particularly, be used for providing transformable tension and compression damping force when automobile gear shift and push-pull cable carry out performance tests such as strong rigidity, life-span, and can export damping force and displacement signal real-time dynamicly.
Background technology
Should carry out performance tests such as strong rigidity, life-span by actual entrucking state or emulation mode behind the automobile gear shift assembly.These tests should be tested by gear shift, gear selecting path, stroke, load and cycle index under the environment provided condition, whether reach design and product quality requirement with the performance of judging automobile gear shift assembly.More than all tests need be load force of push-pull cable load end simulation of automobile gear shift.Manufacturer often adopts spring to do load at present, perhaps directly connects wheel box.Lack versatility, inconvenience is installed, also inconvenience collection measurement data signals is further analyzed.
Because kind, the specification of automobile gear shift are more.Therefore to carry out all-round property testing to these different automobile gear shift assemblies, need one of specialized designs to provide and change the tension and compression damping force of regulating, and can export damping force and displacement signal real-time dynamicly.
Summary of the invention
The object of the present invention is to provide a kind of damping unit of automobile gear shift assembly test usefulness, the tension and compression damping force that the adjusting knob of adjusting damped cylinder can be regulated output when automobile gear shift push-pull cable push-and-pull damping unit, has promptly been exported damping force and displacement signal.The present invention has good versatility, operability.
In order to achieve the above object, the present invention adopts following technical proposals:
A kind of damping unit of performance test of automobile gear shift assembly, comprise the damped cylinder that is fixedly mounted on the installing plate, it is characterized in that at the fixing line slideway of installing plate upper edge damped cylinder the axis of the piston centerline direction, sliding advancing slip motion block and the back sliding shoe of joining on line slideway, have on the advancing slip motion block and connect the screw that push-pull cable is used, advancing slip motion block is connected a pull pressure sensor with the back between the sliding shoe, and back sliding shoe is fixedlyed connected with the damper piston axle, and back sliding shoe also connects a displacement transducer.
Above-mentioned damped cylinder is made up of two cylinder bodies, and on installing plate, the joining damping of its two cylinder body throttling place has two adjusting knobs regulating the damping force size by screw retention.
