Description

Technical Field

[0001] This invention relates to the field of suspension assembly technology, specifically to a fine-tuning device for the front and rear suspension assembly of a bus chassis. Background Technology

[0002] With the rapid development of the bus industry, people's requirements for bus performance, safety and comfort are increasing day by day. As an important part of the bus, the assembly quality of the bus chassis directly affects the overall performance of the bus. Bus chassis assembly involves multiple parts and complex operation lines. Most production lines require manual operation, which is difficult to operate. In order to improve the accuracy and efficiency of bus chassis assembly, reduce the difficulty of workers' operation, and improve product quality and production efficiency, the bus chassis front and rear suspension assembly fine adjustment device has emerged.

[0003] Chinese patent CN105752205B discloses a fine-tuning device for the front and rear suspension assembly of a bus chassis. It includes a base, an adjusting seat, and supporting components, with the suspension supported on the supporting components. The adjusting seat is hinged to the base at its center, and a Z-axis rotation drive mechanism is provided between the adjusting seat and the base, allowing the suspension to rotate around the Z-axis. The supporting components include a first supporting assembly, a second supporting assembly, and a Y-axis rotation support assembly. The suspension is supported on the first and second supporting assemblies, and also on the Y-axis rotation support assembly, which is mounted on the adjusting seat. When the Y-axis rotation support assembly is activated, the suspension can rotate around the Y-axis. This invention enables fine-tuning of the degrees of freedom of the front and rear suspensions of a bus chassis, thereby reducing the difficulty of operation for workers, improving product assembly progress, and increasing production efficiency.

[0004] However, the above-mentioned technical solution reduces the difficulty of operation for workers and helps to improve the assembly progress of the product by fine-tuning the degrees of freedom of the front and rear suspensions of the vehicle chassis. Although this device can fine-tune the front and rear suspensions, it has poor stability for overall angle adjustment and is prone to affecting the installation of the suspension for independent adjustment structures, resulting in a mediocre adjustment effect of the device. Therefore, it needs to be improved by the staff. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] (1) By setting up an installation platform, connecting plate, drive gear, transmission gear plate, hydraulic rod, electric telescopic rod, lead screw, assembly frame and rollers, when in use, the hydraulic rod is driven, the hydraulic rod drives the transmission gear plate at the front end to move, the transmission gear plate drives the drive gear connected to the surface to rotate, the drive gear drives the movable rod installed on the inner wall to rotate, and the connecting plate at the top of the movable rod drives the installation platform at the top to adjust the angle, thereby fine-tuning the angle of the bus suspension at the top. The electric telescopic rods inside the two support columns are connected to the power supply at the same time, thereby driving the bus suspension at the top of the installation platform to adjust the height. The two rotating rods drive the lead screws with opposite threads at the bottom to rotate, and the lead screw drives the assembly frame connected to the surface to adjust the height. The rollers on both sides of the bottom of the assembly frame are used to stabilize and adjust the height, which makes it easy to move the whole device and store it inside the installation frame. The support columns on both sides stabilize the device, thereby achieving the effect of fine-tuning the angle of the bus suspension and making it easy to adjust the height and move the whole device.

[0020] (2) By setting up the mounting sleeve, the second servo motor, the overlapping plate and the buffer pad, the threaded rod drives the threaded sleeve with the surface thread connection to adjust the height, and a limit rod is inserted at the bottom end of the threaded sleeve. The limit rod is fixed to the inner bottom wall of the mounting sleeve, which makes it easy to adjust the height of the threaded sleeve stably, thereby adjusting the height of the suspension at the top of the buffer pad. The height of the threaded sleeve is relatively short, and it is easy to control the adjustment height of the threaded sleeve, thereby achieving the effect of fine adjustment of the suspension height and making it easy for the staff to operate.

[0021] (3) By setting up a fixed block, a placement plate, a limiting slide, a connecting sleeve, a tension spring and a positioning plate, a placement plate is set at the top of the two fixed blocks around the perimeter and in the middle through a telescopic rod. This makes it easy to adjust the height of the placement plate stably. The limiting clamps can clamp the two sides of the suspension, which makes it easy to adjust the size of the suspension. A tension spring is installed on the inner wall of the connecting sleeve. One end of the tension spring is installed on the inner wall of the placement plate through the positioning plate. This makes it easy to stretch the two limiting clamps inward, which can stably clamp the suspension, thus achieving the effect of convenient clamping and fixing of the suspension, and making it easy to adjust the height stably with the threaded sleeve.

[0022] (4) By setting up a laser rangefinder, a lateral balancer, a longitudinal balancer and warning lights, the laser rangefinder is used to measure the distance to the bus chassis, which makes it easier for staff to adjust the distance. The lateral balancer and longitudinal balancer are used to measure the balance of the installation platform. The four warning lights on the top of the installation platform show the lateral points of the installation platform. When the warning light at a certain point is lit, it indicates which position the installation platform is inclined to, thus achieving the effect of facilitating the display of lateral points and measuring the distance to the bus chassis.

Driving the hydraulic rod 7 moves the transmission gear plate 6 at its front end, which in turn drives the drive gear 5, which in turn rotates the movable rod 3 mounted on the inner wall. The connecting plate 4 at the top of the movable rod 3 then adjusts the angle of the top mounting platform 1, thereby fine-tuning the angle of the bus suspension at the top.

A tension spring 29 is installed on the inner wall of the connecting sleeve rod 26. One end of the tension spring 29 is installed on the inner wall of the placement plate 24 through the positioning plate 30, which facilitates the extension of the two limiting clamps 28 inward, which can stably clamp the suspension.

[0046] Example 4:

[0047] Please see Figures 1 to 7 As shown, light-transmitting slots 31 are provided on both sides of the top of the installation platform 1, and an assembly slot 32 is provided in the middle of the top of the installation platform 1. A controller 33 is fixedly connected to the bottom of the inner wall of the assembly slot 32, and a laser rangefinder 34 is fixedly connected to the middle of the bottom wall of the assembly slot 32.

[0048] In use, a laser rangefinder 34 is installed at the top center of the mounting platform 1 via the assembly slot 32. The laser rangefinder 34 is used to measure the distance to the bus chassis, which is convenient for the staff to adjust the distance. A lateral balancer 35 and a longitudinal balancer 36 are installed on the top of the mounting platform 1. The lateral balancer 35 and the longitudinal balancer 36 are used to measure the balance of the mounting platform 1. The four warning lights 37 on the top of the mounting platform 1 indicate the lateral position of the mounting platform 1. The warning light 37 at the point that is lit indicates which position the mounting platform 1 is leaning towards.

[0049] Working principle: In use, the hydraulic rod 7 is driven, which moves the transmission gear plate 6 at the front end. The transmission gear plate 6 drives the drive gear 5, which is meshed with the front end, to rotate. The drive gear 5 drives the movable rod 3 installed on the inner wall to rotate. The connecting plate 4 at the top of the movable rod 3 drives the top mounting platform 1 to adjust its angle, thereby fine-tuning the angle of the bus suspension at the top. Multiple sets of electric telescopic rods 8 are evenly distributed inside the two support columns 9 on both sides of the bottom of the connecting plate 2. The electric telescopic rods 8 inside the two support columns 9 are synchronously connected to the wiring, so that the electric telescopic rods 8 are synchronously powered on. This drives the bus suspension at the top of the mounting platform 1 to adjust its height. The operator then connects the first servo motor 12 to the power supply. The output end drives the drive rod 13 to rotate, which in turn drives the two transmission wheels 38 on the surface to rotate. Both transmission wheels 38 drive the transmission belt 39 on the inner wall to rotate, which in turn drives the drive wheel 40 on the inner wall to rotate. The two drive wheels 40 then drive the two rotating rods 41 to rotate, which in turn drive the opposing threaded lead screws 42 at their bottom ends to rotate. The lead screws 42 then drive the assembly frame 43, which is threaded on the surface, to adjust its height. The assembly frame 43 is stably adjusted in height within the mounting frame 10 via sliding blocks 44 on both sides. This stabilizes the rollers 45 on both sides of the bottom of the assembly frame 43, making it easy to move the entire device and store it inside the mounting frame 10. The support columns 9 on both sides provide stable support. The support device has a second servo motor 15 installed on the inner bottom wall of each of the two mounting cylinders 14. When the operator connects the power to the second servo motor 15, the output end of the second servo motor 15 drives the transmission rod 16 to rotate. The transmission rod 16 drives the threaded rod 17 at the top to rotate. The threaded rod 17 drives the threaded sleeve 18 with the surface threaded connection to adjust the height. A limit rod 19 is inserted into the bottom end of the threaded sleeve 18 and is fixed to the inner bottom wall of the mounting cylinder 14, thereby facilitating the stable adjustment of the height of the threaded sleeve 18 and thus adjusting the height of the suspension at the top of the buffer pad 21. Telescopic rods 23 are inserted around the top and in the middle of the two fixed blocks 22, and a placement plate 24 is provided at the top of the telescopic rods 23, thereby facilitating the stable adjustment of the placement plate 24. The suspension is height-adjustable, and multiple sets of connecting sleeves 26 are inserted into both sides of the placement plate 24. A sliding plate 27 is provided on the top surface of the connecting sleeve 26, and the sliding plate 27 is slidably connected to the limiting groove 25 at the top of the placement plate 24, which facilitates the stable pulling of the connecting sleeve 26. A limiting clamp 28 is provided at one end of the connecting sleeve 26, which can clamp the two sides of the suspension, thereby facilitating the adjustment and fixing of the suspension size. A tension spring 29 is installed on the inner wall of the connecting sleeve 26, and one end of the tension spring 29 is installed on the inner wall of the placement plate 24 through the positioning plate 30, which facilitates the inward stretching of the limiting clamps 28 on both sides, which can stably clamp the suspension. The distance to the bus chassis is measured by a laser rangefinder 34, which facilitates the staff to adjust the distance.The balance of the mounting platform 1 is measured using a lateral balancer 35 and a longitudinal balancer 36. Four warning lights 37 on the top of the mounting platform 1 indicate its lateral tilt; the indicator light illuminating at any given point indicates the direction the mounting platform 1 leans.
