Abstract
Description
Technical Field
[0001] The invention belongs to the field of transmission detection, and in particular relates to a hybrid vehicle transmission detection device. Background Art
[0002] In a car, the transmission is the component that enables the car to obtain different traction and speed under different operating conditions such as starting, climbing, turning, and accelerating. It has the function of changing the transmission ratio and expanding the torque and speed of the drive wheels.
[0003] The engine of the extended-range hybrid vehicle is mainly used as a generator to charge the battery, and does not directly drive the vehicle. When the battery is fully charged, the vehicle runs in pure electric mode; when the battery is insufficient, the engine starts to generate electricity to charge the battery, thereby extending the driving range; when the overall structure of the extended-range hybrid vehicle is set, the output end of the motor is generally coaxial with the input shaft of the transmission to improve the transmission efficiency. Since the extended-range hybrid vehicle always relies on the motor to drive, after long-term driving, the motor and transmission need to be disassembled and repaired. Since the engine is set up separately and only used for power generation, it can be maintained separately.
[0004] During the production stage of extended-range hybrid vehicles, after the transmission and drive motor are connected, special equipment is used to perform coaxiality correction and detection to ensure that the two can effectively transmit power. Then the drive motor and transmission module are installed on the chassis as a whole. When the vehicle needs to be repaired after use, the drive motor and transmission are disassembled. General 4S stores do not have special equipment to perform coaxiality correction and detection work, and when installing the transmission, hoisting is usually adopted. Due to the heavy weight of the transmission and the irregular shape of the transmission shell, it is difficult to ensure that the coaxiality of the motor output shaft and the transmission input shaft reaches the original factory required accuracy during the connection of the drive shaft. For example, the transmission offline detection positioning platform described in CN117825041B, the transmission is not fixed in this patent, and it may be offset due to vibration during the detection process, which will affect the detection. At the same time, the transmission itself has factors such as shaking during the hoisting process, so it is difficult to adjust the angle direction during the process. Therefore, this modified patent has a series of improvements. In addition, the equipment used for alignment in the prior art is usually special equipment used by automobile manufacturers, which is expensive and can generally only be used for a single model. For automobile aftermarket service companies such as 4S stores or related testing and appraisal agencies, there is a need for a transmission testing equipment that is relatively low in price, easy to use, easy to adjust, and applicable to a variety of models.

[0032] like Figure 2-5As shown, the clamping mechanism 2 includes two symmetrically arranged side plates 2015, between which a top plate 2011 and a bottom plate 2014 are arranged in parallel, and the top plate 2011 and the bottom plate 2014 are slidably symmetrically provided with a clamping device with a width adapted to the spacing between the two side plates 2015, and a through hole 2016 is provided at the center of the top plate 2011 and the bottom plate 2014, and the bottom plate 2014 is located on both sides of the through hole 2016 along the side plates 2 015 A second through hole 2012 is symmetrically provided in the length direction, a connecting rod 210 is rotatably provided in the second through hole 2012, and also includes a receiving plate 2021, the transmission 7 is placed on the top of the receiving plate 2021, and one end of a movable rod 2022 is fixedly provided at the bottom of the receiving plate 2021, the other end of the movable rod 2022 passes through the first through hole 2016 and is rotatably connected to one end of the connecting rod 210, and the other end of the connecting rod 210 is rotatably connected to the clamping device. The clamping device includes a horizontal plate 208, which is slidably arranged between the top plate 2011 and the bottom plate 2014. The ends of the two horizontal plates 208 that are close to each other are rotatably connected to the connecting rod 210. The ends of the two horizontal plates 208 that are away from each other are provided with wedges. A clamping plate 203 is rotatably arranged on the inclined surface of the wedge. A spring 205 is fixedly arranged on the inclined surface of the wedge, and the spring 205 is connected to the clamping plate 203. The end of the wedge away from the horizontal plate 208 is rotatably provided with a rotating plate 207. A spring 204 is fixedly provided on 7, and the spring 204 is connected to the bottom of the clamping plate 203. A pressing block 2031 is provided on the top of the clamping plate 203. A through groove 2013 is symmetrically provided on both sides of the two through holes 2012. A flip plate 206 with adapted width is rotatably provided in the through groove 2013. A cylinder 209 is provided at the bottom of the bottom plate 2014 along the length direction, and a slider 2091 is provided at the output end of the cylinder 209. A slide groove 2061 is provided at the bottom of the flip plate 206 along the length direction, and the slider 2091 is slidably connected to the slide groove 2061.During use, the output end of cylinder 1 209 works to drive the slider 2091 to move to both sides, pushing the flip plate 206 to make it in a horizontal state. At this time, the rotating plate 207 connected to the flip plate 206 is also in a horizontal state. The spring 1 204 fixedly connected to the rotating plate 207 will push the bottom outer side of the pressing block 2031 to flip inward; the transmission 7 is placed on the receiving plate 2021 through hanging. Due to the dead weight of the transmission 7, the receiving plate 2021 and the movable rod 2022 move downward. The bottom of the movable rod 210 drives the connecting rod 210 to rotate, thereby pulling the horizontal plate 208 inward. During the inward movement of the clamping plate 203, the transmission 7 is gradually squeezed to achieve the purpose of fixing the transmission 7. By setting the spring 1 204, the clamping plate 203 can adjust the tilt angle according to the spring elastic force and the pressure of the transmission 7, so that even if the left and right ends of the transmission 7 (. Figure 4 When the transmission 7 is asymmetrical, the inclination angles of the clamping plates 203 at both ends will be different, and finally the entire clamping mechanism will be stationary after the force is balanced; a spring three is sleeved on the movable rod 2022 between the top plate 2011 and the bottom plate 2014, and a fixing block is provided on the movable rod 2022, and the two ends of the spring three are connected to the top of the bottom plate 2014 and the bottom of the fixing block (not shown in the figure). When it is necessary to release the clamping operation of the transmission 7, it is only necessary to contract the cylinder one 209 to make the slider 2091 disengage from the slide groove 2061, so that the flip plate 206 flips downward under the action of external force, and the rotating plate 207 also flips downward, so that the spring one 204 is separated from the clamping plate 203, and the clamping plate 203 flips outward under the action of the spring two 205, thereby releasing the clamping operation of the transmission 7, and the transmission 7 can be taken out at this time. After the transmission 7 is taken out, under the elastic action of the spring three, the receiving plate 2021 and the movable rod 2022 move upward to the initial position to facilitate the next work. It should be noted that the sliding range of the rotating plate 207 needs to be controlled on the upper surface of the flip plate 206, and the pressing block 2031 should be made of a material with a soft texture and high friction, such as rubber.
[0033] like Figure 6-7As shown, the connecting mechanism 3 includes a fixed ring 301, a fastening device and a rotating ring plate 303. A through hole 3014 is provided in the center of the fixed ring 301. A plurality of sliding holes 3011 connected to the through hole 3014 are evenly provided on the circumference of the outer wall of the fixed ring 301. The fastening device is slidably provided in the sliding hole 3011. An annular groove 3015 is provided on the side of the fixed ring 301 close to the transmission 7. An annular slider 3034 is provided on one side of the rotating ring plate 303. The annular slider 3034 is slidably arranged in the annular groove 3015. The fixed ring 301 is provided with a through groove 3012 connected to the sliding hole 3011 on one side close to the rotating ring plate 303, and a second through hole 3033 is provided at the center of the rotating ring plate 303. A plurality of arc-shaped through grooves 3031 are evenly provided along the circumference of the second through hole 3033 on the rotating ring plate 303. The fastening device includes a sliding rod 302, one end of the sliding rod 302 is located in the sliding hole 3011, and the other end is located in the first through hole 3014. The end of the sliding rod 302 located in the sliding hole 3011 is provided with a lever 3021, and the lever 30 21 is slidably connected to the through groove 3012 and the arc-shaped through groove 3031; a U-shaped block 3022 is fixedly arranged at one end of the sliding rod 302 located in the through hole 1 3014, a threaded pressure rod 3023 is threadedly connected to the side wall of the U-shaped block 3022, the U-shaped block 3022 is adapted to the flange 701 arranged at the input shaft end of the transmission 7, and the flange 701 can be pressed tightly into the U-shaped block 3022 by twisting the threaded pressure rod 3023, and a rotating lever 3032 is arranged on the side of the rotating ring plate 303 away from the fixed ring 301. It also includes a vertically arranged upright plate 4, wherein a groove 401 is provided on the upright plate 4, a through hole three 402 is provided at the center of the groove 401, a plurality of threaded holes two 403 are evenly arranged on the circumference of the through hole three 402, a plurality of threaded holes one 3013 are evenly arranged on the circumference of the through hole one 3014 on the fixing ring 301, the threaded hole one 3013 corresponds to the threaded hole two 403, two pressure sensors 404 are provided in the groove 401, the two pressure sensors 404 are symmetrical about the center of the groove 401 and are located on the same vertical line, the pressure sensors 404 are electrically connected to the angle adjustment device 107, the fixing ring 301 is provided in the groove 401, a fixing plate 5 is provided on the side of the upright plate 4 away from the fixing ring 301, the motor one 8 is provided on the fixing plate 5, and the output shaft of the motor one 8 is located in the through hole three 402.After properly aligning the positions of the flange 701 and the U-shaped block 3022, rotate the lever 3032 so that the arc-shaped through groove 3031 squeezes the lever 3021 to slide inward, thereby causing the entire fastening device to move inward until the U-shaped block 3022 abuts the flange 701, and then twist the threaded pressure rod 3023 to press the flange 701 to relatively fix the entire connecting mechanism 3 and the transmission 7, and then relatively fix the connecting mechanism 3 and the vertical plate 4 through screws, threaded hole 1 3013 and threaded hole 2 403. Since the connection structure needs to be adjusted in angle and direction (accompanied by the rotation of the connection structure), the threaded hole 1 3013 and the threaded hole 2 403 may be misaligned. Therefore, as a second embodiment, the threaded hole 2 403 can be set to an arc-shaped through groove structure (such as. Fig. 9 ), and a groove 405 (as shown in FIG. 4 ) is provided on the other side for accommodating a nut adapted to the screw. Fig.10 As shown in FIG. 1 , the ultimate goal is to make the output end of the motor 8 and the input shaft of the transmission 7 consistent and relatively fixed. Since the flanges 701 of different transmissions 7 are of different sizes, the required sliding distance of the fastening device is also different. At the same time, the sliding direction of the fastening device is also different if the rotating ring plate 303 rotates in different directions, such as Figure 6 As shown, from the perspective of the transmission 7, when tightening is required, it is sufficient to rotate counterclockwise to make the tightening device slide inwards, and vice versa, it is sufficient to rotate clockwise.
[0034] like Figure 1 , 8As shown, the two middle connecting rods of the scissor lift device 101 are provided with screw rods 102, and the screw rods 102 are symmetrically provided with threaded parts with opposite thread directions, and the two threaded parts are respectively threadedly connected with the two connecting rods, and the scissor lift device 101 can be driven to rise and fall by rotating the screw rods 102. The first level adjustment device includes a first bottom plate 103, and the two ends of the first bottom plate 103 are symmetrically provided with slide rails 104 parallel to the input shaft of the transmission 7, and the slide rails 104 are slidably provided with a sliding table 106, and the middle part of the sliding table 106 is hollow, and the first bottom plate 103 is provided with a cylinder 2 105 along the direction of the slide rail 104, and the output end of the cylinder 2 105 is connected to the sliding table 106, and the sliding table 106 is provided with the second level adjustment device and the angle adjustment device 107. The second level adjustment device comprises a second bottom plate, and the tops of the two ends of the second bottom plate are symmetrically provided with a second slide rail 108 perpendicular to the input shaft of the transmission 7, and the bottom of the second bottom plate near the motor 1 8 is rotatably connected to the sliding table 106. The angle adjustment device 107 comprises an arc-shaped tooth portion 1073, a gear 1072 and a second motor 1071, and the bottom of the second bottom plate away from the motor 1 8 is fixedly provided with the arc-shaped tooth portion 1073, and the sliding table 106 is provided with the second motor 1071, and the second motor 1071 is arranged parallel to the second slide rail 108, and the output end of the second motor 1071 is provided with a gear 1072, and the gear 1072 meshes with the arc-shaped tooth portion 1073. Since the transmission 7 is of different sizes and has an irregular shape, there may be an angle deviation when it is placed on the clamping mechanism, and it may not be aligned with the motor 8. Therefore, the position of the transmission 7 needs to be adjusted. After the connecting mechanism 3 is fixed, it can be aligned with the groove 401 by adjusting the azimuth adjusting mechanism. First, the first horizontal adjustment device is adjusted to make the connecting mechanism 3 fit on the vertical plate 4, and then the second horizontal adjustment device and the scissor lift 101 are adjusted to make the connecting mechanism 3 roughly align with the groove 401, and then the first horizontal adjustment device is adjusted to place the connecting mechanism 3 into the groove 401. At this time, due to the height difference between the input shaft end and the output shaft end of the transmission 7, the transmission 7 The input shaft end of the transmission 7 is not horizontal (during the adjustment process, the angle adjustment device 107 needs to be adjusted first to make the input shaft end of the transmission 7 horizontal to the naked eye). When the connecting mechanism 3 is placed into the groove 401, the fixing ring 301 will squeeze the two pressure sensors 404. The two pressure sensors 404 will compare the pressures they receive. When the value of the upper pressure sensor 404 is larger than that of the lower pressure sensor 404, the motor 2 1071 drives the arc-shaped tooth portion 1073 to move downward, thereby adjusting the output shaft end of the transmission 7 to move downward, thereby achieving angle adjustment, until the values of the two pressure sensors 404 are consistent; when the value of the lower pressure sensor 404 is larger, the operation can be reversed.It should be noted that the motion trajectory of the arc-shaped tooth portion 1073 is an arc, and the radius of the arc is the distance from the rotation axis of the second bottom plate to the farthest point on the arc-shaped tooth portion 1073 .
[0035] Working principle: The crane hoists the transmission 7 to the appropriate position of the receiving plate 2021 (generally, the center lines of the two are on the same vertical line). Under the action of the gravity of the transmission 7, the receiving plate 2021 and the movable rod 2022 slide downward, driving the connecting rod 210 to rotate, thereby causing the horizontal plate 208 and the connected components to slide inward until the pressing block 2031 presses the transmission 7. When the force is balanced, the receiving plate 2021 and the movable rod 2022 no longer move downward. At this time, the connecting mechanism 3 is sleeved on the flange 701, and the sliding rod 302 is rotated to make the fastening device slide inward until the U-shaped block 3022 and the fixing ring 301 abut. At this time, the threaded pressing rod 3023 is screwed to press the flange 701, and then the azimuth adjustment mechanism is adjusted to align it with the groove 401. First, adjust the first horizontal adjustment device The connection mechanism 3 is placed so as to fit on the vertical plate 4, and then the connection mechanism 3 is roughly aligned with the groove 401 by adjusting the second horizontal adjustment device and the scissor lift device 101, and then the connection mechanism 3 is placed in the groove 401 by adjusting the first horizontal adjustment device. During the process of placing the connection mechanism 3 in the groove 401, the fixing ring 301 will squeeze the two pressure sensors 404, and the two pressure sensors 404 will compare the pressures received. When the upper pressure sensor 404 has a larger value than the lower pressure sensor 404, the motor 2 1071 drives the arc-shaped tooth portion 1073 to move downward, thereby adjusting the output shaft end of the transmission 7 to move downward to achieve angle adjustment, until the values of the two pressure sensors 404 are consistent; when the value of the lower pressure sensor 404 is larger, the reverse operation can be performed. When the values of the two pressure sensors 404 are consistent, the connection mechanism 3 and the vertical plate 4 are fixed to each other by a screw, and the motor 1 8 is connected to the input shaft of the transmission 7 through a coupling at this time, and detection can be performed.
