[0002] Currently, in whole vehicle drum tests, test vehicles need to be bound to the drum stand as required. For two-wheel drive vehicles, the non-drive wheels need to be positioned and fixed after the drum is aligned. The existing fixing brackets are split structures, and each time the vehicle is changed for adjustment, the whole thing needs to be disassembled and reassembled, which is inefficient. The straps used to secure the wheels are also tight, which is complicated, inefficient, and labor-intensive. Summary of the Invention

The distance between the fixing bracket and the wheel is adjustable using a telescopic rod, and the tire locking is achieved through a screw-based fine-tuning mechanism. The adjusted position is secured with positioning bolts to prevent loosening. When changing test vehicles, there is no need to disassemble the integrated fixing bracket; adjustment via the screw is sufficient. Operation is simple and convenient, and the use is safe and reliable. This new mechanism improves the operability and convenience of drum-binding operations and meets the requirements for the operation of a complete vehicle drum test platform. The technical solution is as follows: A vehicle non-drive wheel positioning and locking bracket for a vehicle drum test bench, characterized in that: it includes a movable bracket 1 and a movable crossbeam 2 inserted at the middle of the upper left surface of the movable bracket 1; a push-pull handle 3 is connected to the middle of the right edge of the upper surface of the movable crossbeam 2; an adjustment device 4 is connected to the middle of the left side surface of the movable crossbeam 2; locking screws 5 are inserted at the middle of the left and right sides of the upper surface of the adjustment device 4 and at the left and right sides of the upper edge of the rear surface of the movable bracket 1; clamping devices 6 are slidably inserted at the front and rear edges of the left side surface of the adjustment device 4; a non-drive wheel 7 is inserted between the two clamping devices 6; the movable bracket 1 includes a base plate 1-1, a support block 1-2, a square tube 1-3, and threaded holes 1-4; the support block 1-2 is connected to the middle of the upper surface of the base plate 1-1; the square tube 1-3 is connected to the middle of the upper surface of the support block 1-2; threaded holes 1-4 are symmetrically provided at the middle of the left and right sides of the rear surface of the square tube 1-3; the support block 1-2 is shaped as follows: The device has a tapered shape. The movable crossbeam 2 is inserted through the square tube 1-3. The locking screw 5 is inserted into the threaded hole 1-4. The adjusting device 4 includes a hollow plate 4-1, a telescopic plate 4-2, a lead screw 4-3, and a socket 4-4. The telescopic plate 4-2 is movably inserted into the middle of the front surface of the hollow plate 4-1.

[0006] Reference Figures 1-4 The vehicle non-drive wheel positioning and locking bracket of the whole vehicle drum test bench is characterized by: including a movable bracket 1 and a movable crossbeam 2 inserted at the middle of the upper left surface of the movable bracket 1; a push-pull handle 3 connected to the middle of the right edge of the upper surface of the movable crossbeam 2; an adjustment device 4 connected to the middle of the left side surface of the movable crossbeam 2; locking screws 5 inserted at the middle of the left and right sides of the upper surface of the adjustment device 4 and at the left and right sides of the upper edge of the rear surface of the movable bracket 1; clamping devices 6 slidably inserted at the front and rear edges of the left side surface of the adjustment device 4; and a non-drive wheel 7 inserted between the two clamping devices 6.
[0007] In use, first connect the movable bracket 1 to the T-shaped track on the test bench, then push the movable bracket 1 to align it with the non-drive wheel 7 and fix the movable bracket 1. Then, the operator holds the push-pull handle 3 to push the movable crossbeam 2 to contact the adjusting device 4 with the non-drive wheel 7. Then, turn the locking screw 5 to fix the movable crossbeam 2. Then, adjust the adjusting device 4 so that the two clamping devices 6 clamp the non-drive wheel 7. Finally, turn the locking screw 5 to clamp the clamping device 6 and the test can be carried out.
[0008] When releasing the non-drive wheel 7, first loosen the locking screw 5 on the adjusting device 4, then the operator pulls the two clamping devices 6 to the right to separate the two clamping devices 6 from the non-drive wheel 7. Then loosen the locking screw 5 on the movable bracket 1, and finally pull the push-pull handle 3 to the right, which simultaneously drives the adjusting device 4 to the right through the movable crossbeam 2 to separate it from the non-drive wheel 7.
[0009] Furthermore, the movable support 1 includes a base plate 1-1, a support block 1-2, a square tube 1-3, and threaded holes 1-4. The support block 1-2 is connected to the middle of the upper surface of the base plate 1-1, and the square tube 1-3 is connected to the middle of the upper surface of the support block 1-2. Threaded holes 1-4 are symmetrically provided at the middle of the left and right sides of the rear surface of the square tube 1-3. The support block 1-2 is conical in shape. The movable crossbeam 2 is inserted through the square tube 1-3, and the locking screw 5 is inserted into the threaded holes 1-4.
[0010] In use, the rear chord inserts the base plate 1-1 onto the T-shaped track on the test bench, pushes the support block 1-2 to move the base plate 1-1 on the T-shaped track to align the adjusting device 4 with the non-driving wheel 7, and the operator pushes and pulls the movable crossbeam 2 to slide within the square tube 1-3 to adjust the distance between the adjusting device 4 and the non-driving wheel 7. After adjustment, the locking screw 5 is rotated within the threaded hole 1-4, simultaneously pressing the locking screw 5 against the movable crossbeam 2. Furthermore, the adjusting device 4 includes a hollow plate 4-1, a telescopic plate 4-2, a lead screw 4-3, and a socket 4-4. The telescopic plate 4-2 is movably inserted into the middle of the front surface of the hollow plate 4-1. The hollow plate 4-1 and the telescopic plate 4-2 are connected to each other by the lead screw 4-3. The sockets 4-4 are symmetrically arranged at the outer edges of the front surfaces of the hollow plate 4-1 and the telescopic plate 4-2. The locking screw 5 is inserted into the outer edges of the upper surfaces of the hollow plate 4-1 and the telescopic plate 4-2.
[0011] In use, the operator rotates the lead screw 4-3 inside the hollow plate 4-1. At the same time, the lead screw 4-3 and the telescopic plate 4-2 are connected by threads, which can drive the telescopic plate 4-2 to move inside the hollow plate 4-1. Then, the telescopic plate 4-1 drives the clamping device 6 to move and cooperates with the clamping device 6 on the hollow plate 4-1 to clamp the non-drive wheel 7. Finally, tighten the locking screw 5 on the blade mesh on the hollow plate 4-1 and the telescopic plate 4-2 to clamp and fix the clamping device 6.
[0012] Furthermore, the clamping device 6 includes a horizontal column 6-1, a vertical plate 6-2, and a fastening groove 6-3. The vertical plate 6-2 is symmetrically connected between the upper and lower horizontal columns 6-1 at the middle of the left and right edges. The fastening groove 6-3 is provided at the middle of the right edge of the outer surface of the right vertical plate 6-2. The horizontal column 6-1 is inserted through and inserted into the insertion hole 4-4.
[0013] In use, the operator hooks their finger into the buckle groove 6-3 and pushes and pulls the upright plate 6-3. At the same time, the upright plate 6-3 drives the horizontal column 6-1 to slide in the insertion hole 4-4. When adjusting the telescopic plate 4-2, the telescopic plate 4-2 drives the horizontal column 6-1 to move. Finally, the horizontal column 6-1 on the hollow plate 4-1 and the horizontal column 6-1 on the telescopic plate 4-2 cooperate to clamp the non-drive wheel 7. At the same time, the locking screw 5 is used to fix the horizontal column 6-1.
