The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
FIGS. 1-3 illustrate an integrated performance testing system for an automotive shifter according to a preferred embodiment of the present utility model, comprising: a frame 1, a transmission device 2, an encoder 3, a support bracket 4, a horizontal linear driving mechanism 5 and a force sensor 6.
The transmission device 2 comprises a gear 21 and a rack 22, wherein the gear 21 is vertically arranged and pivoted with the frame 1. The rack 22 is placed horizontally and is in driving connection (preferably directly engaged) with the gear 21. The end surface of the gear 21 is radially provided with a plurality of supporting blocks 23 in a protruding mode, and the supporting blocks 23 are uniformly distributed around the axis of the gear 21; the supporting block 23 is detachably connected with a ball clamping tool 24, the ball clamping tool 24 is suitable for clamping a ball of a test sample, and the center of gravity of the ball clamping tool 24 falls on the axis of the gear 21. Thus, the ball of the test piece rotates in synchronization with the gear 21.
The encoder 3 (having an angle sensor) is mounted on the frame 1, and an output shaft of the encoder 3 is linked with the gear 21 and is used for detecting the rotation angle of the gear 21.
The support bracket 4 is arranged above the rack 22 and supports the rack 22 to ensure that the rack 22 is in a horizontal placement state and enable the rack 22 to be driven so as to drive the gear 21 to rotate.
The horizontal linear driving mechanism 5 is arranged on the frame 1.
One end of the force sensor 6 is connected with the support bracket 4, and the other end of the force sensor 6 is connected with the horizontal linear driving mechanism 5.
Before testing, the ball head of the test sample is put into the ball head clamping tool 24, and then the ball head clamping tool 24 is fixed on the supporting blocks 23 (it can be understood that after testing, the disassembling process and the installing process are in reverse order), or the ball head clamping tool 24 and the ball head of the test sample can be synchronously installed. The shape of the ball clamping tool 24 is specifically selected by the shape of the ball of the test sample, so that the ball clamping tool 24 can clamp the ball of the test sample. During testing, the horizontal linear driving mechanism 5 drives the force sensor 6 to move, so that the force sensor 6 drives the support bracket 4 to horizontally move while feeding back force; in this way, the rack 22 moves synchronously along with the support bracket 4, so that the linkage gear 21 rotates, and the ball clamping tool 24 arranged on the support block 23 rotates together based on synchronous linkage of the gear 21 and the support block 23; thus, the encoder 3 can detect the rotation angle of the gear 21. In this way, the force sensor 6 can detect the magnitude of the driving force received by the ball of the test piece, and the encoder 3 can detect the magnitude of the rotation angle generated by the ball of the test piece. Thus, the two items of data are input into the control system, and the parameter relation between the gear shifting force and the gear shifting angle is obtained.
Importantly, the plurality of support blocks 23 are uniformly distributed around the axis of the gear 21, so that the center of gravity of the additional weight brought by the plurality of support blocks 23 falls on the axis of the gear 21 and is not overlapped on the ball head of the test sample, and the test result can be more accurate. In addition, the center of gravity of the ball clamping tool 24 falls on the axis of the gear 21, so that the ball is not added to the test sample, and the test result is further more accurate. Moreover, the weight of the gear 21 and the rack 22 is supported by the frame 1, so that the weight of the gear is not additionally added to the ball head of the test sample, and the accuracy of the test result is further improved. And, the transmission accuracy of the gear 21 and the rack 22 is also higher.
Based on the fact that the test sample piece and the ball clamping tool 24 are required to be installed into the test position (namely connected with the supporting blocks 23) before testing, the installation process is difficult due to the position interference and the movement interference of the supporting blocks 23 and the supporting brackets 4. In order to improve the convenience of the installation and the disassembly of the test sample and the ball head clamping tool 24, preferably, the frame 1 is also connected with a lifting driving mechanism 7, the lifting driving mechanism 7 is in driving connection with a horizontal guide rail 8, and the horizontal guide rail 8 is movably connected with a horizontal sliding block 9. The horizontal slide 9 is connected with the support bracket 4 and supports the support bracket 4. The force sensor 6 is detachably connected to the support bracket 4 and/or the force sensor 6 is detachably connected to the horizontal linear drive mechanism 5. At this time, before the installation or the disassembly, one of the horizontal linear driving mechanism 5 and the support bracket 4 is disassembled, so that the lifting driving mechanism 7 can drive the horizontal guide rail 8, the horizontal sliding block 9 and the support bracket 4 to synchronously lift, and the space of the test position is opened. It should be noted that, based on the fact that the support bracket 4 needs to be driven by the horizontal linear driving mechanism 5 to perform horizontal movement during the test, the rack 22 is driven to perform horizontal movement, and thus the support bracket 4 needs to be movably matched with the horizontal guide rail 8 through the horizontal sliding block 9.
Wherein preferably the force sensor 6 is connected to the support bracket 4 by means of a first bolt assembly 10. The connection stability between the force sensor 6 and the support bracket 4 is enough, and the installation and the disassembly processes are labor-saving and simple. It will be appreciated that, as an alternative, the two may be fixed by magnetic attraction, or the like.
Similarly, referring to fig. 2, the force sensor 6 is connected with an extension connecting seat 12 through a second bolt assembly 11, and the extension connecting seat 12 is in driving connection with the horizontal linear driving mechanism 5. In this way, the process of installing and detaching the force sensor 6 and the extension connecting seat 12 is also labor-saving and simple. And by adding the extension connecting seat 12, the force sensor 6 has a good installation position.
Preferably, the horizontal linear driving mechanism 5 is a first linear motor, and a first output slider 51 of the first linear motor is in driving connection with the extension connection seat 12. It will be appreciated that the first horizontal linear drive mechanism 5 may also be an electric push rod or the like. It can be understood that the control and positioning accuracy of the first linear motor is high.
Preferably, the lifting drive mechanism 7 is a second linear motor, and the second output slider 71 of the second linear motor is in driving connection with the support bracket 4. It will be appreciated that the second horizontal linear drive mechanism 5 may also be an electric push rod or the like. It can be understood that the control and positioning accuracy of the second linear motor is high.
Preferably, the transmission 2 is provided with a pair, and the pair of transmissions 2 are radially arranged at intervals in the horizontal direction. The arrangement can enable the whole system to run more stably, and the clamping force to the ball head of the test sample piece is also more stable.
Preferably, the ball clamping tool 24 comprises two split-shaped clamping blocks and a third bolt assembly for fixing the two clamping blocks together, and two ends of the clamping blocks are respectively connected with two supporting blocks 23 belonging to different gears 21. Therefore, the two ends of the clamping block are forcedly fixed and move synchronously, and the movement stability of the ball head of the test sample can be further improved.
Preferably, the rack 1 is further connected with a control system, and the control system is connected with a signal wire, wherein the signal wire is used for connecting a circuit board of the test sample, so that the control system can measure the gear trigger angle of the test sample.
Obviously, when test samples with different specifications are required to be tested, the size of the replacement transmission device 2 can be replaced, so that the comprehensive performance test system for the automobile gear shifter has universality.
The above embodiments are only preferred embodiments of the present utility model, and the scope of the present utility model is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present utility model are intended to be within the scope of the present utility model as claimed.
