As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Fig. 1 shows a gearbox simulation test apparatus according to a preferred embodiment of the present invention, comprising: the device comprises a main case 1, a synchronous motor 4, a lifting plate 5, a horizontal moving plate 7 and a fixed frame 14.

Referring to fig. 4, the main cabinet 1 is used for driving a transmission case, a buffer block 2 is arranged in the main cabinet 1, the buffer block 2 is preferably made of rubber or plastic, the buffer block 2 is connected with an output shaft 3 of the main cabinet, and the output shaft 3 of the main cabinet is used for driving the transmission case.

An output shaft of the synchronous motor 4 is connected with the buffer block 2, and the output shaft of the synchronous motor 4 is coaxially arranged with the output shaft 3 of the mainframe box. In this way, the power of the synchronous motor 4 is transmitted to the gearbox through the output shaft of the synchronous motor 4 and the output shaft 3 of the mainframe box, so that necessary test power is provided for the gearbox. In the case of power input, see fig. 1, the load system 46 is connected to the output shaft of the transmission via a rotating shaft (the rotating shaft of the load system 46 corresponds to a wheel, so that the transmission can be detected under simulated actual conditions), and if necessary, the load system 46 can be mounted on a horizontal linear conveying mechanism to adjust the distance between the two load systems 46. The supplementary insertion explanation is that, in this section, based on the adoption of the synchronous motor 4, compared with the asynchronous motor adopted in the prior art, the size of the synchronous motor 4 is smaller under the same power; moreover, on the premise that the synchronous motor 4 meets the power requirement, the output shaft of the synchronous motor 4 and the output shaft 3 of the mainframe box are coaxially arranged, so that the mainframe box 1 does not need to be provided with more transmission mechanisms, and the volume of the mainframe box 1 is smaller so as to reduce the occupied space. In addition, the buffer block 2 is respectively connected with the output shaft of the synchronous motor 4 and the output shaft 3 of the mainframe box, so that rigid connection between the output shaft of the synchronous motor 4 and the output shaft 3 of the mainframe box is avoided, overlarge vibration can be avoided, the coaxiality requirement between the output shaft of the synchronous motor 4 and the output shaft 3 of the mainframe box can be reduced, and the processing difficulty is reduced.

Referring to fig. 1, the lifting plate 5 is located right below the main chassis 1 and supports the main chassis 1; the bottom of the lifting plate 5 is connected with a plurality of lifting screws 6. It can be understood that when the lifting plate 5 is lifted or lowered, the mainframe box 1 is supported on the lifting plate 5, and the mainframe box 1 can be lifted and lowered synchronously, so that the output shafts of different gearboxes can be in butt joint with the rotating shaft of the load system 46, that is, the universality of the gearbox simulation detection equipment is improved.

Referring to fig. 1-3, the horizontal moving plate 7 is provided with a plurality of vertical through holes, threaded sleeves 8 are movably sleeved in the vertical through holes, and each lifting screw 6 is in threaded connection with one of the threaded sleeves 8 in a one-to-one correspondence manner.

Thus, under the driving of the driving motor 112, the driving sprocket 11, the chain 10, and the driven sprocket 9 sequentially transmit the rotation of the plurality of thread sleeves 8 around their axes, and the thread sleeves 8 are connected to the lifting screw 6 by the threads, and the thread sleeves 8 cannot move axially, so that the lifting screw 6 will ascend or descend when the thread sleeves 8 rotate, thereby achieving the lifting movement of the lifting plate 5.

Referring to fig. 2 and 3, a slide block 12 is arranged at the bottom of the horizontal moving plate 7; and a supporting block 13 is fixed at the bottom of the horizontal moving plate 7, and the supporting block 13 is provided with a threaded through hole. The top of the fixed frame 14 is provided with a slide rail 15, and the slide block 12 is movably matched with the slide rail 15; the fixed frame 14 is provided with a horizontal driving mechanism 16, the horizontal driving mechanism 16 is connected with a horizontal screw rod 17 in a driving way, and the horizontal screw rod 17 is in threaded connection with the threaded through hole of the supporting block 13. The arrangement is that the horizontal driving mechanism 16 drives the horizontal screw 17 to move along the axial direction of the horizontal screw 17, so as to drive the horizontal moving plate 7 to move along the extending direction of the slide rail 15; synchronously, the lifting plate 5 is moved by the horizontal moving plate 7. Therefore, the gearbox installed on the main case 1 can move horizontally to adjust the position in the horizontal direction, so that the output shafts of different gearboxes can be in butt joint with the rotating shaft of the load system 46, and the universality of the gearbox simulation detection equipment is improved. The supporting block 13 is used not only as a transmission element, but also as an element for supporting the horizontal screw 17, so that the structure is dual-purpose, and the structural compactness is improved.

The horizontal driving mechanism 16 comprises a vertical motor 27 and a speed reducer 28 in driving connection with the vertical motor 27, and the horizontal screw 17 is in driving connection with the speed reducer 28; the fixed mount 14 is fixedly connected with the vertical motor 27 through a cross beam 29. Meanwhile, the vertical motor 27 is supported by the support column. It is understood that as further alternatives to the horizontal drive mechanism 16, the horizontal drive mechanism 16 may be a combination of a motor, a worm gear, and a worm; or a combination of a motor and a belt, etc.

As a further preferred embodiment:

referring to fig. 7, the gearbox simulation detection apparatus further includes a swing seat 18, and the swing seat 18 is sandwiched between the lifting plate 5 and the main chassis 1, and is supported by the lifting plate 5 and supports the main chassis 1.

A stationary sun gear 19 is fixed on the lifting plate 5, the sun gear 19 is horizontally placed, the swing base 18 is pivotally connected with the sun gear 19 through a first pivot shaft, the axis of the first pivot shaft is collinear with the axis of the sun gear 19, the swing base 18 is connected with a planetary gear 20 through a second pivot shaft, and the planetary gear 20 is meshed with the sun gear 19.

It should be added that, because the volumes of the synchronous motor 4 and the main cabinet 1 are reduced, the synchronous motor 4 and the main cabinet 1 are allowed to swing along with the swing base 18 without spatial interference, and the swing base 18 can swing to meet the actual requirements and purposes.

As a further preferred embodiment: a connecting line of the initial gear teeth of the sun gear 19 and the axis of the sun gear 19 is a first line segment, a connecting line of the termination gear teeth of the sun gear 19 and the axis of the sun gear 19 is a second line segment, and continuous gear teeth are arranged between the initial gear teeth and the termination gear teeth; the included angle between the first line segment and the second line segment is 90 degrees. In this way, the oscillating base 18 can be limited by the start gear teeth and the end gear teeth, respectively. For example, when the planet teeth roll into contact with the initial teeth, the planet gears 20 cannot continue to roll around the sun gear 19 because the outer surface wall of the sun gear 19 has no splines, thereby achieving alignment and spacing. That is, the planetary gear 20 is positioned and limited by the start gear teeth of the sun gear 19 and the end gear teeth of the sun gear 19, so that the production efficiency can be greatly improved, and particularly, the swing seat 18 can be prevented from excessively swinging and collapsing, thereby avoiding serious safety accidents. It should be added that, according to the actual production situation, only the main cabinet 1 needs to be horizontally adjusted by 90 ° back and forth.

As a further preferred embodiment: referring to fig. 8, in order to facilitate the operation of the first positioning pin 22, the transmission simulation detection device further includes a first clamping mechanism 23, the first clamping mechanism 23 includes a first prying shaft 24, a first lever 25 pivotally connected to the first prying shaft 24, and one end of the first lever 25 is in driving connection with the first positioning pin 22; a first compression spring 26 is connected to the lever, and the first compression spring 26 is used for urging the first positioning pin 22 toward the first positioning hole 21.

As a further preferred embodiment: referring to fig. 4 and 5, the main cabinet 1 includes a cabinet 30, a vertical plane rotation support bracket 31, a mounting plate 32, and a second clamping mechanism 33. The outer wall of the box body 30 is provided with a boss 34, the box body 30 is provided with a horizontal through hole 35, and the horizontal through hole 35 penetrates through the boss 34 from the inner wall of the box body 30 towards the direction of the boss 34, so that the output shaft 3 of the main case extends out of the box body 30 along the horizontal through hole 35. The boss 34 is provided with an annular groove 36 which surrounds the periphery of the horizontal through hole 35 and is coaxial with the horizontal through hole 35, and the vertical surface rotating support frame 31 is provided with a sleeve hole 37 which is movably matched with the annular groove 36; the vertical surface rotating support frame 31 is fixedly connected with a plurality of mutually spaced and mutually parallel insertion rods 38, the mounting plate 32 is provided with a plurality of scattered second positioning holes 39, the insertion rods 38 are used for inserting the second positioning holes 39, and the insertion angle of the mounting plate 32 can be adjusted through the combination of different second positioning holes 39, so that the orientation of the gearbox is adjusted. The angle of the gearbox can be further adjusted by turning the vertical surface rotating the support bracket 31. To facilitate locking and unlocking of the vertical surface rotation support 31, the second clamping mechanism 33 is used to lock the vertical surface rotation support 31 to the housing 30.

As a further preferred embodiment: referring to fig. 9, the second clamping mechanism 33 includes a second prying shaft 40 and a second lever 41 pivotally connected to the second prying shaft 40, one end of the second lever 41 is connected to a second positioning pin 42, the box body 30 is provided with an avoiding hole 43 (see fig. 6), two ends of the avoiding hole 43 are respectively communicated with the inside of the box body 30 and the annular groove 36, and the second positioning pin 42 is movably inserted into the avoiding hole 43; the vertical surface rotating support frame 31 is provided with a plurality of third positioning holes 44, and the plurality of third positioning holes 44 are distributed around the axis of the groove at intervals; a second hold-down spring 45 is connected to the second lever 41, and the second hold-down spring 45 is used to drive the second positioning pin 42 to press the third positioning hole 44. It is understood that, as an alternative to the second clamping mechanism 33, the second clamping mechanism 33 may be a common brake mechanism, or a magnetic element, and the vertical surface rotation support 31 is limited to swing by magnetic force.

The working principle is as follows:

based on the different relative positions of the output shaft of different gearboxes and the input shaft thereof, the situation that the output shaft of the gearbox faces different may occur after the different gearboxes are installed on the main case 1, in order to enable the different gearboxes to be installed on the simulation detection equipment of the gearbox, the output shaft of the gearbox is in coaxial butt joint with the rotating shaft of the load system 46, height adjustment, horizontal movement adjustment and horizontal rotation adjustment need to be carried out on the main case 1, and the universality is stronger. Therefore, the horizontal driving mechanism 16 drives the horizontal screw 17 to move, so as to drive the horizontal moving plate 7 to move, and the lifting screw 6 of the lifting plate 5 is linked with the horizontal moving plate 7 when moving in the horizontal direction, so that the lifting plate 5 can realize horizontal movement adjustment. The drive motor 112, the driving chain wheel 11, the chain 10, the driven chain wheel 9, the lifting screw 6 and the thread bush 8 are sequentially driven, so that the height adjustment of the lifting screw 6 is realized, namely the height adjustment of the lifting plate 5 is completed. The horizontal rotation adjustment is completed by swinging the swing base 18 with respect to the rising and falling plate 5. And, the swing base 18 is supported by the lifting plate 5, and the main cabinet 1 is supported by the swing base 18. Thus, the precondition required for the respective orientation adjustments of the main cabinet 1 is constituted.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
