Abstract
Description
Technical Field
[0001] This utility model relates to the field of abnormal noise detection technology, specifically to a motorcycle engine abnormal noise detection device. Background Technology
[0002] The motorcycle engine is fixed to the motorcycle frame via an engine suspension. The engine suspension consists of multiple links, and rubber bushings are installed at the connection points for shock absorption.

During engine operation, the suspension connection points will vibrate and produce abnormal noise. Therefore, a motorcycle engine abnormal noise detection device is needed to perform a test before the suspension is installed, simulating engine vibration to detect whether abnormal noise will occur.

[0031] Reference Figures 1-9 As shown, the motorcycle engine abnormal noise detection device of this utility model includes a base 1, an engine suspension 2, a first connecting mechanism 3 symmetrically arranged on the base and in contact with the engine suspension, a second connecting mechanism 4 symmetrically arranged on the base and in contact with the engine suspension, and a detection mechanism 5 arranged on the base. The detection mechanism includes a second support seat 53 fixedly arranged on the base, a first slide groove 52 fixedly arranged on the base, a first support seat 51 slidably arranged on the first slide groove, a first limiting block 54 arranged on the first slide groove, and a drive assembly 55 arranged on the first support seat and the second support seat. One end of the engine suspension is in contact with the first connecting mechanism, and the other end is in contact with the second connecting mechanism. The first limiting block is fixed on the first slide groove by screws to limit the first support seat, preventing the first support seat from moving on the first slide groove. When the engine suspension needs to be removed, the first limiting block is first removed, and the first support seat is pushed to move, so that the first support seat is disengaged from the engine suspension. The drive assembly is used to simulate engine vibration to detect the engine suspension.
[0032] Specifically, the drive assembly includes a motor 551 fixedly mounted on a first support base, a first output shaft 552 fixedly mounted on the motor, a first crankshaft 553 fixedly mounted on the first output shaft, a second output shaft 554 fixedly mounted on the first crankshaft, a second slide groove 555 fixedly mounted on the second output shaft, a third output shaft 556 slidably mounted on the second slide groove, a second crankshaft 557 fixedly mounted on the third output shaft, a fourth output shaft 558 fixedly mounted on the second crankshaft and rotatably mounted on the second support base, and a first adjustment device 55 mounted on the first crankshaft. 9. A second adjustment device 550 is installed on the second crankshaft; the motor drives the first output shaft to rotate, the first output shaft drives the first crankshaft to rotate, the first crankshaft drives the second output shaft to rotate, the second output shaft drives the third output shaft to rotate, the third output shaft drives the second crankshaft to rotate, and the second crankshaft drives the fourth output shaft to rotate; the first crankshaft and the second crankshaft synchronously drive one end of the engine to make a circular motion to simulate engine vibration; the first adjustment device and the second adjustment device have the same structure and working principle, and the radius of the circular motion can be adjusted by adjusting the length to simulate different vibration amplitudes.
[0033] Specifically, the first adjusting device includes a first connecting rod 5591 rotatably sleeved on the first crankshaft, a second connecting rod 5592 rotatably sleeved on the engine suspension, a third sliding groove 5593 fixed on the first connecting rod, a first threaded rod 5594 fixed on the first connecting rod and sliding along the third sliding groove, multiple fourth sliding grooves 5595 fixed on the first threaded rod, and a first adjusting ring 5596 rotatably mounted on the first connecting rod and the first threaded rod. Rotating the first adjusting ring causes the first threaded rod to slide on the third sliding groove, adjusting the total length of the first connecting rod and the second connecting rod, thereby adjusting the radius of the circumferential motion. The first connecting rod is provided with a protrusion that fits into the fourth sliding groove. Adjusting the total length of the first connecting rod and the second connecting rod needs to be adjusted together with the first connecting mechanism.
[0034] Specifically, the second adjustment device includes a third connecting rod 5501 rotatably sleeved on the second crankshaft, a fourth connecting rod 5502 rotatably sleeved on the engine suspension, a fifth sliding groove 5503 fixed on the third connecting rod, a second threaded rod 5504 fixed on the third connecting rod and sliding along the fifth sliding groove, a plurality of sixth sliding grooves 5505 fixed on the second threaded rod, and a second adjusting ring 5506 rotatably sleeved on the second connecting rod and the second threaded rod.
[0035] Specifically, the first connecting mechanism includes a third support 31 slidably disposed on the base, a first push plate 32 slidably disposed on the base and in contact with the third support, a first electric telescopic rod 33 with one end fixed to the first push plate and the other end fixed to the base, a fourth support 34 slidably disposed on the base, a second push plate 35 slidably disposed on the base and in contact with the fourth support, a second electric telescopic rod 36 with one end fixed to the second push plate and the other end fixed to the base, and a second limiting block 37 disposed on the base; the first push plate is fixedly connected to the third support; the second push plate is fixedly connected to the third support; and the second push plate is fixedly connected to the third support. The four support seats are fixedly connected; the positions of the third and fourth support seats can be adjusted by the first and second electric telescopic rods. When operating the first and second adjustment devices, the first and second electric telescopic rods need to be adjusted synchronously. If the positions of the third and fourth support seats are not adjusted, the bushing will be in a stretched or compressed state before testing, which can easily cause damage; the second limit block is fixed to the base with screws. When the engine suspension needs to be removed, the second limit block is removed first, and the fourth support seat is pushed to move so that the fourth support seat is disengaged from the engine suspension.
[0036] Specifically, the second connecting mechanism includes a fifth support seat 41 slidably disposed on the base, a sixth support seat 42 slidably disposed on the fifth support seat, a first clamping assembly 43 disposed on the sixth support seat, a seventh support seat 44 slidably disposed on the base, an eighth support seat 45 slidably disposed on the seventh support seat, a second clamping assembly 46 disposed on the eighth support seat, and a third limiting block 47 disposed on the base; the second clamping assembly has the same structure as the first clamping assembly; the first clamping assembly and the second clamping assembly respectively clamp the two ends of the engine suspension; when the drive mechanism drives one end of the engine suspension to make a circular motion, the sixth support seat will slide on the fifth support seat, the fifth support seat will slide on the base, the eighth support seat will slide on the seventh support seat, and the seventh support seat will slide on the base; the third limiting block is fixed to the base by screws; when the engine suspension needs to be removed, the third limiting block is first removed, the seventh support seat is pushed to move, so that the eighth support seat is disengaged from the engine suspension.

The head engages with the first rotating block. When the first rotating block rotates, it drives multiple clamping heads to slide synchronously on the sixth support seat to clamp the engine suspension. In use, the third adjusting ring is pulled outward, and the third adjusting ring slides on the seventh slide groove. The first spring is stretched, and the first gear ring and the second gear ring disengage. The third adjusting ring is rotated, and the third adjusting ring drives the first rotating block to rotate through the seventh slide groove, which in turn drives multiple clamping heads to clamp. After the third adjusting ring is released, the first spring returns to its original position, driving the third adjusting ring to return to its original position. The first gear ring and the second gear ring engage to prevent the third adjusting ring from rotating due to vibration.
