Description

Technical Field

[0001] The present application relates to the technical field of shift block structures, and in particular to a multi-speed shift block assembly. Background Art

[0002] The shift handle adjusts the gearbox through the shift block structure. Since the shift block will move horizontally or swing during the shifting process, shift blocks with different structures will provide different shifting feel. However, once the shift block is produced, its structural form is fixed, and the corresponding shifting feel will be roughly the same. In order to meet the experience of most users, the shift block assembly will be adjusted in the direction of moderate lightness or heaviness during the debugging process, which is difficult to take into account for operators who are accustomed to a light or heavy feel. Summary of the Invention

[0003] The purpose of this application is to provide a multi-speed shift block assembly with adjustable center of gravity.

[0004] To achieve the above objectives, the present application provides a multi-speed shift block assembly: including a shift block, the shift block including a shaft sleeve, the outer side surface of the shaft sleeve having a C-shaped clip plate, the end of the C-shaped clip plate away from the shaft sleeve having a shift fork, and the shift fork is provided with a position-adjustable counterweight, which is suitable for changing the center of gravity position of the shift block, so that the swing inertia of the shift block changes, thereby changing the force of the shift feedback, and thus changing the shift feel, so that more operators can obtain a shift experience that is more suitable for them.

[0005] As a preference, a screw hole is provided on the shift fork, and the counterweight comprises a stud suitable for threaded cooperation with the screw hole. One end of the stud has an end cap for cooperation with tools such as a wrench, thereby making the operation of screwing the stud in and out easier.

[0006] As a preference, the stud is made of a polymer synthetic material and has an interference fit with the screw hole, and the end cap is made of a corrosion-resistant alloy material. The distance of the end cap relative to the shift fork will change the center of gravity position of the entire shift block assembly.

[0007] As a preference, the outer side surface of the C-shaped buckle plate has a reinforcing rib, and the reinforcing rib extends from the outer side surface of the sleeve to the outer side surface of the shift fork, so that the entire shift block has higher structural strength.

[0008] As a preferred embodiment, the sleeve is equipped with a reversing shaft and a transmission member at the same time. The reversing shaft includes a sliding shaft body passing through the sleeve. The side wall of the sleeve is provided with a through pin hole passing through the inner and outer walls. The sliding shaft body is provided with a transmission pin hole, which is suitable for being coaxial with the through pin hole. The transmission member includes a pin shaft portion, which is suitable for passing through the through pin hole and the transmission pin hole at the same time. The matching structure is very compact and stable.

[0009] As a preference, one end of the sliding shaft body located outside the shaft sleeve is fixedly connected to a limiting ring; the other end of the sliding shaft body located outside the shaft sleeve is provided with a limiting pin hole passing through the outer surface for installing a bayonet structure to further limit the movement distance of the sliding shaft body.

[0010] As a preference, the portion of the sliding shaft body located between the limiting ring and the shaft sleeve is suitable for cooperating with the frame of the shift mechanism to form a sliding pair and a rotating pair, thereby ensuring the position stability of the entire shift block assembly.

[0011] As a preference, both ends of the pin shaft portion are located outside the sleeve, one end of the pin shaft portion is fixedly connected to a ball head through the crankshaft portion, and the other end is fixedly connected to a retaining ring to prevent the transmission member from detaching from the shift block.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] (1) By providing a height-adjustable configuration structure on the shift fork, the swing inertia of the shift block can be adjusted, which can provide the shift handle with different light and heavy feedback, and can meet the usage habits of a wider range of operators;

[0014] (2) The design has a compact structure, high strength, good working stability, good transmission continuity, crisp and smooth shifting process, and fast response speed. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0027] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or units is not necessarily limited to those steps or units expressly listed, but may include other steps or units not expressly listed or inherent to such process, method, product or apparatus.

[0028] like Figure 1-8The multi-speed shift block assembly shown includes an integrally formed shift block 2. The shift block 2 is the most important part of the entire multi-speed shift block assembly and is an asymmetric special-shaped structure. The specific structure of the shift block 2 includes a sleeve 201. The sleeve 201 has cylindrical inner and outer walls with uniform wall thickness. The outer side surface of the sleeve 201 has a C-shaped clip 203. The C-shaped clip 203 extends upward from the middle height of the outer side surface of the sleeve 201. The end of the C-shaped clip 203 away from the sleeve 201 has a shift fork 205, which is a component that directly contacts the shift gear and adjusts the position of the shift gear. The outer side surface of the C-shaped clip 203 has a reinforcing rib 204 for improving the structural strength of the C-shaped clip 203. The reinforcing rib 204 extends from the outer side surface of the sleeve 201 to the outer side surface of the shift fork 205, so that the entire shift block 2 has a higher structural stability.

[0029] The shift fork 205 is provided with a position-adjustable counterweight 4, which can change the center of gravity of the shift block 2. Specifically, a screw hole 206 structure is opened on the shift fork 205, and the counterweight 4 includes a stud 401, which is exactly matched with the screw hole 206 thread, and the stud 401 is made of a polymer synthetic material, such as common nylon material, which can be interference fit with the screw hole 206, so that the stud 401 and the screw hole 206 have good stability when screwed to any depth and are not easy to slip due to inertia. One end of the stud 401 is provided with an end cap 402, which is solid and has a larger diameter. It is usually made of corrosion-resistant alloy material, such as common nickel-based alloy. The end cap 402 can be matched with the stud 401 through a snap-fit ​​structure and fixedly connected to the stud 401 using curing glue. Finally, the outer side of the end cap 402 is generally provided with a flat structure that can cooperate with a wrench tool, or a groove structure that can enhance friction is provided as a force point for rotating the entire counterweight 4.

[0030] The sleeve 201 is also equipped with a reversing shaft 1 and a transmission member 3 to form a multi-speed shift block assembly. The reversing shaft 1 includes a sliding shaft body 101 passing through the sleeve 201. The outer side surface of the sliding shaft body 101 fits the inner wall of the sleeve 201, and the two remain coaxial. The side wall of the sleeve 201 is provided with a through pin hole 202 that passes through the inner and outer walls. There are two through pin holes 202. The axes of the two through pin holes 202 are perpendicular to the axis of the sleeve 201. The sliding shaft body 101 is provided with a transmission pin hole 103 that passes through the opposite outer sides and can remain coaxial with the through pin hole 202. The specific structure of the transmission member 3 includes a pin shaft portion 301, which can pass through the through pin hole 202 and the transmission pin hole 103 at the same time, and the outer side surface of the pin shaft portion 301 fits with the inner wall of the through pin hole 202 and the transmission pin hole 103, and the three keep the axis collinear. The end of the sliding shaft body 101 outside the shaft sleeve 201 is fixedly connected to the limit ring 102, and the limit ring 102 and the sliding shaft body 101 are an integrated structure. The diameter of the limit ring 102 is obviously larger than the diameter of the sliding shaft body 101, and the other end of the sliding shaft body 101 outside the shaft sleeve 201 is provided with a through outer side surface The limiting pin hole 104 is for the bayonet structure to pass through, thereby limiting the position of the two ends of the sliding shaft body 101. The portion of the sliding shaft body 101 located between the limiting ring 102 and the shaft sleeve 201 is suitable for cooperating with the frame of the shift mechanism to form a sliding pair and a rotating pair. The freedom and movement stroke of the sliding shaft body 101 are limited. It can be seen that the function of the limiting ring 102 is to prevent the sliding shaft body 101 from being separated from the frame of the shift mechanism. Both ends of the pin shaft portion 301 are also located outside the shaft sleeve 201, and one end of the pin shaft portion 301 is fixedly connected to the ball head 302 through the crankshaft portion 302. 04. Since there are generally two reinforcing ribs 204 on the outer side of the shift paddle block 2, the crankshaft portion 302 is usually arranged between the two reinforcing ribs 204. The ball head 304 is used to cooperate with the ball seat structure at the end of the shift handle to achieve manual control. The other end of the pin shaft portion 301 is fixedly connected with a retaining ring 303. The pin shaft portion 301 will not be separated from the sleeve 201 under the restriction of the crankshaft portion 302 and the retaining ring 303, and the retaining ring 303 is usually fixedly connected to the pin shaft portion 301 with a bolt structure, which makes it more convenient to perform disassembly and assembly operations.

[0031] Working principle: Since the freedom of the sliding shaft body 101 is limited by the frame of the shift mechanism, the reversing shaft 1 can only slide or rotate along its own axis. When the ball head 304 is pressed down by the shift handle, the shift fork 205 will tilt away from the shift gear. At this time, the ball head 304 applies a force along the axis of the sliding shaft body 101 to the shift block 2, and the position of the shift fork 205 aligned with the shift gear will change. The ball head 304 is lifted by the shift handle again, and the shift fork 205 returns to the initial inclination angle and cooperates with other shift gears again, and the cooperation position of the shift fork 205 and the newly matched shift gear also changes. At this time, the ball head 304 allows the shift block 2 to return to its initial position along the axis of the sliding shaft body 101, and the shift operation can be completed. Since the shift fork 205 has five different positions and a slot structure, the multi-speed shift block structure has the ability to adjust at least five gears.
