Description

Technical Field

[0001] This utility model relates to the field of chassis dynamometer technology, specifically a motorcycle chassis dynamometer. Background Technology

[0002] A motorcycle chassis dynamometer is a professional testing device used to simulate road driving conditions and accurately measure the power performance, fuel economy, and emissions of a motorcycle. Its core principle is to use a mechanical structure to bring the motorcycle's rear wheel into contact with rollers simulating the road surface, using a loading device to simulate driving resistance, while simultaneously collecting and analyzing key data.

[0003] In the field of motorcycle performance testing, with the diversification of motorcycle usage scenarios and the increasing demands of users for vehicle power, handling and durability on various road surfaces, the industry is also pursuing more accurate and comprehensive test data. Traditional chassis dynamometers mostly use single-characteristic rolling to simulate road surfaces, which can only reproduce one type of conventional road condition such as asphalt roads. They are difficult to cover the surface differences of multiple road conditions such as cement roads and gravel roads, resulting in a large deviation between test results and actual working conditions. Therefore, we propose a motorcycle chassis dynamometer. Utility Model Content

[0006] The rotating mechanism includes two round rods that are rotatably connected to the two side walls of the inner cavity of the dynamometer body. The ends of the two round rods that are close to each other are fixedly connected to mounting plates. Two sets of first rollers, second rollers and third rollers are rotatably installed on the side wall of the two mounting plates that are close to each other. A rotating motor is fixedly installed on the outer wall of one side of the dynamometer body. The output end of the rotating motor passes through the side wall of the dynamometer body and is fixedly connected to the end of one of the round rods.

[0007] A square groove is provided through the middle of the cover plate. When the mounting plate rotates, the first roller, the second roller, and the third roller move through the square groove to the top of the cover plate.

[0008] Preferably, a pad is rotatably connected to one side of the top of the dynamometer body.

[0009] Preferably, an extension plate is fixedly connected to each of the two corners on the side of the cover plate away from the pad plate, and threaded holes are opened through the two extension plates. Through holes are opened through the two side walls of the dynamometer body, and bolts are movably inserted into the two through holes. The two bolts are threadedly connected to the two threaded holes.

[0010] Preferably, the limiting mechanism includes a fixed plate fixedly connected to the top surface of the dynamometer body, an electric pole fixedly installed on one side wall of the fixed plate near the pad plate, a U-shaped plate fixedly connected to the telescopic end of the electric pole, electric telescopic rods fixedly sleeved on both side walls of the U-shaped plate, and a limiting plate fixedly connected to the telescopic ends of the two electric telescopic rods.

[0011] Preferably, the bottom surfaces of both side panels of the U-shaped plate are fixedly connected to sliders, and the top surface of the dynamometer body is provided with two sliding grooves, in which the two sliders are slidably connected respectively.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-4 As shown, a motorcycle chassis dynamometer includes a dynamometer body 1, a cover plate 2 rotatably connected to the top surface of the dynamometer body 1, a rotating mechanism 3 provided in the inner cavity of the dynamometer body 1, and a limit mechanism 5 provided on the top surface of the dynamometer body 1. The rotating mechanism 3 includes two round rods 31 rotatably connected to the two side walls of the inner cavity of the dynamometer body 1, respectively. The ends of the two round rods 31 that are close to each other are fixedly connected to mounting plates 32. Two sets of first rollers 33, second rollers 34 and third rollers 35 are rotatably mounted on the side walls of the two mounting plates 32 that are close to each other. A rotating motor 36 is fixedly mounted on the outer wall of one side of the dynamometer body 1. The output end of the rotating motor 36 passes through the side wall of the dynamometer body 1 and is fixedly connected to the end of one of the round rods 31. A square groove is opened through the middle of the cover plate 2. When the mounting plate 32 rotates, the first rollers 33, second rollers 34 and third rollers 35 move through the square groove to the top of the cover plate 2.

[0018] It should be noted that the surface textures of the first roll 33, the second roll 34, and the third roll 35 are different, which are used to reproduce the driving characteristics of asphalt roads, cement roads, and gravel roads in reality. The two sets of first rollers 33, second rollers 34 and third rollers 35 are arranged in a circular array.

[0019] In practice, by installing the first roller 33, the second roller 34, and the third roller 35 of different specifications on the mounting plate 32, and starting the rotation motor 36, the output end of the rotation motor 36 drives the round rod 31 to rotate. One of the first roller 33, the second roller 34, and the third roller 35 can be moved to the top to contact the motorcycle tire for rotation testing. By changing the positions of the first roller 33, the second roller 34, and the third roller 35, various road surface simulation tests can be performed on the tire, enhancing the comprehensiveness of the test.

[0020] As a technical optimization of this utility model, extension plates 9 are fixedly connected to the two corners of the side of the cover plate 2 away from the pad plate 6. Threaded holes 10 are opened through the two extension plates 9. Through holes are opened through the two side walls of the dynamometer body 1. Bolts 11 are movably inserted into the two through holes. The two bolts 11 are threadedly connected to the two threaded holes 10.

[0021] In practice, the cover plate 2 can be fixed by inserting the bolt 11 into the through hole and the threaded hole 10. The cover plate 2 can be rotated and moved away by removing the bolt 11, which facilitates the maintenance or replacement of the rotating mechanism 3 inside the dynamometer body 1.

[0022] As a technical optimization of this utility model, the limiting mechanism 5 includes a fixed plate 51 fixedly connected to the top surface of the dynamometer body 1. A pole 52 is fixedly installed on the side wall of the fixed plate 51 near the pad plate 6. A U-shaped plate 53 is fixedly connected to the telescopic end of the pole 52. Electric telescopic rods 54 are fixedly sleeved on both sides of the U-shaped plate 53. Limiting plates 55 are fixedly connected to the telescopic ends of the two electric telescopic rods 54. Slider 56 is fixedly connected to the bottom surface of both sides of the U-shaped plate 53. Two sliding grooves 4 are also opened on the top surface of the dynamometer body 1. The two sliders 56 are slidably connected in the two sliding grooves 4 respectively.

[0023] In practice, the electric pole 52 is activated, and the U-shaped plate 53 is moved through the telescopic end of the electric pole 52. The U-shaped plate 53 can be moved to the wheel of the motorcycle that needs to be fixed. By adjusting the telescopic ends of the electric telescopic rods 54 on both sides of the U-shaped plate 53, the two limiting plates 55 can be moved closer to each other to fix the wheel of the motorcycle that needs to be fixed, which is convenient for later testing.

[0024] As a technical optimization of this utility model, a pad plate 6 is rotatably connected to one side of the top of the dynamometer body 1, a support rod 7 is fixedly connected to a corner of the top surface of the dynamometer body 1, and a display screen 8 is fixedly installed at the top of the support rod 7.

[0025] In practice, the use of the pad 6 facilitates the movement of the motorcycle onto the dynamometer body 1, and the use of the display screen 8 facilitates the viewing of the motorcycle's test results, making it convenient to use.

[0026] In use, this invention involves installing different sizes of first rollers 33, second rollers 34, and third rollers 35 onto mounting plate 32. Bolts 11 are inserted into through holes and threaded holes 10 to fix the cover plate 2. The motorcycle is moved onto the dynamometer body 1 using pad plate 6, positioning its test wheel directly above and between the two mounting plates 32. The electric pole 52 is activated, and its telescopic end moves the U-shaped plate 53 to the wheel that needs fixing. Adjusting the telescopic ends of the electric telescopic rods 54 on both sides of the U-shaped plate 53 moves the two limiting plates 55 closer together to fix the motorcycle wheel. The rotating motor 36 is then activated, and its output end drives the round rod 31 to rotate, moving one of the first rollers 33, second rollers 34, and third rollers 35 to the top to contact the motorcycle tire for rotation testing. By changing the positions of the first rollers 33, second rollers 34, and third rollers 35, various road surface simulation tests are performed on the tire.
