Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a self-adaptive electronically controlled hydraulically adjustable spring preload shock absorber. Background Art

[0002] For driving comfort, motorcycles are equipped with shock absorbers. However, each type of motorcycle requires different elastic properties of shock absorbers to achieve optimal comfort according to different driving road conditions. The spring preload, in layman's terms, refers to how much the spring is compressed in advance, which determines whether the spring is harder or softer. If the shock absorber is too soft, the vehicle body will jump up and down. If the shock absorber is too hard, it will bring too much resistance, hindering the normal operation of the spring. Therefore, the driver can adjust the spring preload according to road conditions and his own comfort level. However, the spring preload on existing shock absorbers is generally fixed and cannot be adjusted.

[0003] When using the existing adjustable spring preload shock absorber, the support height of the spring is adjusted by rotating the bolt. After adjustment, the double nut locking effect is used for positioning. However, when the double nut locking structure is used, it is difficult to perform secondary adjustment after the nuts in contact with each other are locked. For this reason, the present application proposes an adaptive electronically controlled hydraulically adjustable spring preload shock absorber. Utility Model Content

[0006] Therefore, the purpose of the present utility model is to provide an adaptive electronically controlled hydraulically adjustable spring preload shock absorber, which drives the worm to rotate by rotating the rotating shaft, and the worm drives the worm wheel to rotate.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0029] This utility model provides an adaptive electronically controlled hydraulically adjustable spring preload shock absorber. By rotating the rotating shaft, the worm is driven to rotate, and the worm drives the worm wheel to rotate. When the worm wheel rotates, it moves up and down under the action of the thread feed to adjust the support height of the spring, thereby adjusting the spring preload. After adjustment, the self-locking function of the worm wheel is used to position the spring, preventing loose connection, improving connection stability, and facilitating adjustment and use. Please refer to Figures 1-4 , including: a shock absorbing mechanism 100, a lifting component 200 and an adjusting mechanism 300.

[0030] The shock absorption mechanism 100 includes a cylinder 110, a main shaft 120, an external thread 130, a support seat 140, a baffle 150, a spring 160, and a damping adjustment cylinder 170. The main shaft 120 is provided at the top of the cylinder 110, the external thread 130 is provided at the lower end of the outer wall of the cylinder 110, the support seat 140 is provided at the lower end of the external thread 130, the baffle 150 is provided at the top of the main shaft 120, the spring 160 is provided at the bottom of the baffle 150, and the damping adjustment cylinder 170 is provided on the side of the cylinder 110.

[0031] The shock absorbing mechanism 100 adopts an existing electronically controlled hydraulic shock absorber.

[0032] The lifting component 200 is arranged on the external thread 130 , and the lifting component 200 includes a worm gear 210 and an internal thread 220 . The internal thread 220 connected to the external thread 130 is arranged inside the worm gear 210 ;

[0033] When the worm wheel 210 rotates, it is connected to the external thread 130 through the internal thread 220, and the worm wheel 210 is lifted and lowered under the action of the thread feed.

[0034] The adjustment mechanism 300 is disposed on the worm gear 210 and includes a bracket 310, a rotating shaft 320, and a worm 330. The bracket 310 is rotatably connected to the bottom of the worm gear 210. The rotating shaft 320 is disposed on the side of the bracket 310. The worm 330 connected to the worm gear 210 is disposed on the rotating shaft 320.

[0035] Among them, an upper rotating sleeve 230 is provided at the bottom of the worm gear 210, and a lower rotating sleeve 340 is provided at the top of the bracket 310. The upper rotating sleeve 230 is rotatably connected to the lower rotating sleeve 340, and a bearing is provided between the upper rotating sleeve 230 and the lower rotating sleeve 340, so that the worm gear 210 is rotatably connected to the bracket 310, and the rotating shaft 320 is rotated to synchronously drive the worm 330 to rotate, and the worm 330 drives the worm wheel 210 to rotate, and the self-locking function of the worm gear is used to limit the position so that the position of the worm wheel 210 is fixed after rotation.

[0036] Since the support seat 140 can rotate freely outside the cylinder 110, a sliding hole 180 is set on the side of the support seat 140, and a sliding rod 350 is set on the bottom of the bracket 310 to connect with the sliding hole 180, so that the bracket 310 can maintain a straight rise and fall outside the cylinder 110.

[0037] Since the rotating shaft 320 needs to be rotated, and a smooth rotating shaft 320 is difficult to rotate, a hexagonal socket 360 is provided at the front end of the rotating shaft 320 for rotating by a hexagonal wrench.

[0038] Since the bracket 310 needs to slide behind the outside of the cylinder 110, a through hole is opened in the center of the bracket 310. The inner diameter of the through hole is larger than the outer diameter of the external thread 130, and the bracket 310 can slide freely outside the external thread 130 through the through hole.

[0039] Since the rotation of the worm gear 210 will cause the bottom of the spring 160 to wear, a gasket is provided on the top of the worm gear 210, and the bottom of the spring 160 is connected to the gasket to protect the spring 160.

[0040] During specific use, the rotating shaft 320 is rotated by a hexagonal wrench, which synchronously drives the worm 330 to rotate, and the worm 330 drives the worm wheel 210 to rotate. When the worm wheel 210 rotates, it is connected to the external thread 130 through the internal thread 220. Under the action of the thread feed, the worm wheel 210 is raised and lowered, and the support height of the spring 160 is adjusted, thereby adjusting the preload of the spring 160. After adjustment, the self-locking function of the worm gear is used to limit the position, so that the position of the worm wheel 210 is fixed after rotation. When adjusting, just rotate the rotating shaft 320.

[0041] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
