Description

Technical Field

[0001] This utility model relates to a fork tube component, specifically to an adaptive height-adjustable motorcycle fork tube assembly. Background Technology

[0002] The motorcycle fork tube assembly is a key component of the motorcycle suspension system, playing a crucial role in the stability and comfort of the motorcycle. The adjustment of the spring preload of the motorcycle fork tube is still in the manual adjustment stage. This adjustment method cannot be adjusted randomly according to changes in road surface and load. With the advancement of technology, people are constantly putting forward new requirements and expectations for the performance of motorcycle shock absorbers. Therefore, traditional motorcycle suspension needs to keep pace with the times to meet market demands.

[0003] In the prior art, 201220232607.9 describes a novel motorcycle front shock absorber. This utility model discloses a novel motorcycle front shock absorber, including a sleeve, a fork tube, a positioning tube, and a shock-absorbing spring. The lower end of the fork tube is located inside the sleeve and slides within it. The positioning tube is located inside the sleeve, with its lower end firmly connected to the lower end of the sleeve, and its upper end is located inside the fork tube and slides within it. The shock-absorbing spring is installed inside the fork tube, positioned between the positioning tube and the fork tube. Hydraulic oil is contained within the sleeve, and a dust cover is fixedly installed on the upper end of the sleeve. This utility model has the advantages of good shock absorption and sealing effect and long service life. By setting the dust cover, it can effectively prevent dirt from entering the gap between the front shock absorber sleeve and the fork tube.

[0004] In the existing technology, motorcycle fork tubes have good shock absorption and sealing effects, long service life, and prevent oil leakage, thereby improving the reliability of the front shock absorber. However, in the existing technology, the spring preload of motorcycle fork tubes cannot be automatically adjusted and needs to be manually adjusted. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides an adaptive height-adjustable motorcycle front fork tube assembly.

[0006] This utility model adopts the following technical solution: an adaptive height-adjustable motorcycle front fork tube assembly, which includes a fork tube assembly, a front mounting component and a rear mounting component. The front mounting component is a pre-mounted accessory, and the rear mounting component is a rear-mounted accessory. The front mounting component has an assembly space, and the rear mounting component is inserted into the assembly space of the front mounting component. A locking component is provided between the front mounting component and the rear mounting component. A plunger rod is provided inside the rear mounting component, and a compression component, which is a compression spring, is provided on the outside of the plunger rod. An oil pipe is provided at the bottom of the plunger rod, and an oil flow component is provided on the oil pipe. A lifting piston is provided at the bottom of the oil pipe.

[0007] The oil flow component is an oil flow hole, which is symmetrically distributed on the oil pipe. A lifting cavity is provided between the lifting piston at the bottom of the oil pipe and the rear-mounted fitting.

[0008] The lifting chamber is a lifting oil chamber, and a locking component is provided at the bottom of the lifting oil chamber, which is a locking valve block.

[0009] The locking valve block and the rear-mounted fitting are locked together, and a locking rod is provided between the locking valve block and the rear-mounted fitting. The locking rod is a locking pin.

[0010] Compared to existing technologies, this invention allows for easier adjustment of the fork spring preload by utilizing the cooperation of a plunger rod and an oil pipe. An oil pipe is located at the bottom of the plunger rod, and a lifting chamber is located at the top of the oil pipe. Hydraulic oil is injected into the lifting chamber, which lifts the oil pipe, which in turn lifts the plunger rod. This allows the plunger rod to be adjusted to a suitable height, thus enabling proper adjustment of the fork spring preload. This eliminates the need for manual adjustment and makes adjusting the motorcycle fork spring preload much more convenient. Attached Figure Description

[0014] In the diagram: 1 is the pre-installed component, 2 is the aftermarket component, 3 is the assembly space, 4 is the locking component, 5 is the plunger rod, 6 is the compression spring, 7 is the oil pipe, 8 is the lifting piston, 9 is the oil flow hole, 10 is the lifting cavity, 11 is the locking valve block, and 12 is the locking rod. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0016] An adaptive height-adjustable motorcycle front fork tube assembly is provided, comprising a fork tube assembly, a front mounting component and a rear mounting component. The front mounting component is a front mounting accessory 1, and the rear mounting component is a rear mounting accessory 2. The front mounting accessory 1 has an assembly space 3, and the rear mounting accessory 2 is inserted into the assembly space 3 on the front mounting accessory 1. A locking component 4 is provided between the front mounting accessory 1 and the rear mounting accessory 2. A plunger rod 5 is provided inside the rear mounting accessory 2, and a compression component, which is a compression spring 6, is provided on the outside of the plunger rod 5. An oil pipe 7 is provided at the bottom of the plunger rod 5, and an oil flow component is provided on the oil pipe 7. A lifting piston 8 is provided at the bottom of the oil pipe 7.

[0017] To allow for proper adjustment of the internal spring preload of the fork tube without manual intervention, the piston rod 5 and the oil pipe 7 work together to adjust the internal spring to the appropriate position. During adjustment, the piston rod 5 and the oil pipe 7 work together. A lifting piston 8 is located at the bottom of the oil pipe 7, and a lifting chamber 10 is located at the bottom of the lifting piston 8. The lifting chamber 10 is filled with hydraulic oil, which lifts the lifting piston 10. The lifting piston 10 then lifts the oil pipe 7 and the piston rod 5, thus adjusting the compression spring 6 to the appropriate position and adjusting its preload. This meets the need for automated adjustment of the compression spring 6's preload. The oil flow component is an oil flow hole 9, symmetrically distributed on the oil pipe 7. The lifting chamber 10 is located between the lifting piston 8 at the bottom of the oil pipe 7 and the rear-mounted accessory 2.

[0018] The lifting chamber 10 is a lifting oil chamber. A locking component is provided at the bottom of the lifting oil chamber. The locking component is a locking valve block 11. The locking valve block 11 and the rear-mounted accessory 2 are locked together. A locking rod 12 is provided between the locking valve block 11 and the rear-mounted accessory 2. The locking rod 12 is a locking pin. The locking pin allows the locking valve block 11 to better seal the assembly between it and the rear-mounted accessory 2, thereby further optimizing the bottom sealing performance of the rear-mounted accessory 2 and meeting the sealing effect requirements of the fork assembly.

[0019] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
