Abstract
The utility model discloses a spring simulated load testing device including two spring mechanisms, a force sensor, a displacement sensor, a piston rod, and a support, the two spring mechanisms are mutually connected, the connecting part penetrates through a through hole of the support and is fixed on the support, one of the spring mechanisms is connected with the piston rod, a force sensor is fixed on the piston rod, the other end of the piston rod is connected with a connecting bar, the displacement sensor is arranged under the piston rod, and the displacement sensor is arranged on a fixing plate connected with the support. The testing device can better stimulate the real conditions, performs endurance test on a gearshift, and is free of detaching the inside of a gearbox, thereby saving costs and improving efficiency.
Description
Technical field
The utility model relates to selector detection technique, is specifically related to a kind of spring simulation load testing device.
Background technology
When selector is carried out to durable test, conventionally need to test together with wheel box, because wheel box is subject to the effect of certain force in actual applications, such as friction force.When testing, the structure of wheel box inside need to remove, very inconvenient, and has increased cost.
Summary of the invention
For the deficiencies in the prior art, the spring simulation load testing device that the purpose of this utility model is to provide a kind of convenience and reduces costs.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of spring simulation load testing device, it comprises 2 spring devices, power sensor, displacement transducer, piston rod and support, described 2 spring devices interconnect, this junction is passed the through hole of support and is fixed on support, one of them spring device connects a piston rod, on described piston rod, be fixed with a power sensor, the described piston rod other end is connected with a pitman, under described piston rod, have a displacement transducer, this displacement transducer is arranged on a fixed head being connected with support.
As the further optimization of such scheme, in described 2 spring devices, another one end is provided with a locking reference column, so that follow-up locking experiment.
As the further optimization of such scheme, described pitman is provided with a threaded hole, with facilitate with selector on main shaft be connected and fixed.
The beneficial effects of the utility model main manifestations is: by adopting device simulate actual conditions of the present utility model, selector is carried out to durable test, need not dismantle wheel box inside, save cost, raise the efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Wherein 1 is support, the 2nd, and through hole, the 3rd, spring device, the 4th, displacement transducer, the 5th, power sensor, the 6th, piston rod, the 7th, pitman, the 8th, locking reference column, the 9th, fixed head.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is done to more specific detail.
As shown in Figure 1, a kind of spring simulation load testing device, it comprises 2 spring devices 3, power sensor 5, displacement transducer 4, piston rod 6 and support 1, described 2 spring devices 3 interconnect, this junction is passed the through hole 2 of support and is fixed on support 1, one of them spring device 3 connects a piston rod 6, on described piston rod 6, be fixed with a power sensor 4, described piston rod 6 other ends are connected with a pitman 7, under described piston rod 6, have a displacement transducer 4, this displacement transducer 4 is arranged on a fixed head 9 being connected with support 1.In described 2 spring devices 3, another one end is provided with a locking reference column 8.Described pitman 7 is provided with a threaded hole.
The present embodiment is when practical application, first the main shaft of selector is connected with the pitman 7 of this device, both sides spring device 3 is carried out to pretension simultaneously, when drag-line drives main shaft rotation, two ends spring device 3 is all subject to the effect of power, after device operation, the pole of gearbox body inside can reciprocally rotate back and forth, carrying out positive hour hands and counterclockwise in rotation, be respectively positive and negative power, by displacement transducer 4 and power sensor 5, detect the variation of the power of 2 directions, then the change curve of exerting oneself, to calculate the variation of the required acting force of selector, to determine the wearing quality of selector.
When doing locking experiment, spring device 3 pretensions can be produced to certain power, then the locked spring device 3 that allows remains constant force.Doing locking experiment is by constant power, to read the size of the power of driving mechanism end.
By reference to the accompanying drawings the utility model preferred implementation is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes.Should be appreciated that the utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
