Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and in particular to a cross-slider shock-absorbing wheel hub and mechanical wheel. Background Technology

[0002] To improve the shock absorption capacity of wheels, shock-absorbing wheel hubs (publication number CN212949959U--a shock-absorbing wheel hub, wheel and vehicle thereof) have been developed. The shock absorption capacity of automobiles is improved by cooperating with the springs of the automobile chassis suspension and the rubber tires.

[0003] The inventors discovered that existing shock-absorbing wheel hubs have a transmission component and a bearing support frame that cooperates with the transmission component between the axle wheel hub and the rim. The axle wheel hub and the rim are connected by a connecting rod-shaped deformable spoke and a spring. The setting of the transmission rod and the bearing support frame allows the axle wheel hub to move relative to the rim. Although shock absorption can be achieved through the deformation of the deformable spoke and the spring, the deformable spoke has a certain rigidity, which will affect the compression deformation of the spring. The spring cannot exert its maximum shock absorption and buffering effect. Moreover, the spring is set independently, which will cause unstable fluctuations in the shock absorption stroke during rotation, and is prone to shock absorption jerking. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a cross-slider shock-absorbing wheel hub and a mechanical wheel. The inner ring of the wheel hub drives the outer ring of the wheel hub to rotate through a cross-slider mechanism. A shock-absorbing spring is sleeved on the cross-shaped slide rail, which plays a major role in shock absorption. Support limiting sliders connected to auxiliary support springs are sleeved on each leg of the cross-shaped slide rail, which play a role in auxiliary shock absorption and limiting the swing of the legs, thus avoiding unstable fluctuations. This solves the problem of poor buffering effect and easy shock absorption jerking of existing shock-absorbing wheel hubs.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] In a first aspect, the present invention provides a cross-slider shock-absorbing wheel hub, comprising an inner wheel ring and an outer wheel ring connected by a cross-slider mechanism. Two opposing support grooves are fixedly provided on the inner and outer wheel rings respectively. The cross-slider mechanism has a cross-shaped slide rail, with a fixed seat fixed at the center of the cross-shaped slide rail. The four legs of the cross-shaped slide rail are slidably disposed in adjacent support grooves. Each leg is fitted with a shock-absorbing spring, a support, and a support limiting slider. The shock-absorbing spring is located between two supports, and the supports are limited by adjacent support grooves and a central fixed seat. An auxiliary support spring is connected to each side of each support limiting slider.

[0007] As a further implementation, the inner ring of the wheel hub is fixedly provided with a first support groove and a first spring lug, the two first support grooves are coaxially arranged, and each first support groove has a first spring lug on both sides for connecting an auxiliary support spring; the outer ring of the wheel hub is fixedly provided with a second support groove and a second spring lug, the two second support grooves are coaxially arranged, and each second support groove has a second spring lug on both sides for connecting an auxiliary support spring.

[0008] As a further implementation, the first spring lug is connected to the support limiting slider on the adjacent leg located in the second support groove via a second auxiliary support spring arranged at an angle.

[0009] As a further implementation, the second spring lug is connected to the support limiting slider on the adjacent leg located in the first support groove via a first auxiliary support spring, and the first auxiliary support spring is perpendicular to the corresponding leg.

[0010] As a further implementation, the support limiting slider is located on the side of the support groove away from the support.

[0011] As a further implementation, the length of the support leg set on the first support groove is greater than the length of the support leg set on the second support groove.

[0012] As a further implementation, the inner wheel hub ring, the cross slider mechanism, and the outer wheel hub ring are coaxially arranged when they are stationary.

[0013] As a further implementation, the cross-shaped slide rail consists of four long, columnar slide rails, which are fixedly connected together by a detachable mounting bracket.

[0014] As a further implementation, the end of the slide rail is provided with a through hole, and a positioning pin that mates with the through hole is fixed on the fixing seat.

[0015] Secondly, the present invention provides a mechanical wheel with a solid rubber tire on the outer rim of the hub.

[0016] The beneficial effects of the present invention are as follows:

[0017] (1) The inner ring of the wheel hub of the present invention drives the outer ring of the wheel hub to rotate through the cross slider mechanism. The cross-shaped slide rail is fitted with a shock-absorbing spring, which plays the main role of shock absorption. The compression of the shock-absorbing spring is not affected by other components, and can exert its maximum buffering capacity. Support limit sliders connected to the auxiliary support springs are fitted on each leg of the cross-shaped slide rail, which play the role of auxiliary shock absorption and limiting the swing of the legs, avoiding unstable fluctuations and improving comfort.

[0018] (2) The present invention eliminates the integrated setting. The outer ring of the wheel hub, the inner ring of the wheel hub and the cross slider mechanism, as well as the cross slider mechanism, can be disassembled. When the wheel hub is damaged, the damaged parts can be disassembled and maintained in a timely manner, which greatly reduces the maintenance cost.

[0019] (3) The length of the support leg set on the first support groove is greater than the length of the support leg set on the second support groove, which effectively avoids contact interference between the cross-shaped slide rail and the inner wall of the outer ring of the wheel hub.

[0020] (4) The auxiliary support spring of the present invention can not only perform the auxiliary shock absorption function, but also reduce the unstable fluctuation of the shock absorption stroke and improve the load-bearing strength of the wheel hub. Attached Figure Description

[0034] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0035] As described in the background section, existing shock-absorbing wheel hubs have a certain rigidity in their deformable spokes, which affects the compression deformation of the spring. The spring cannot achieve its maximum shock absorption effect, and its independent setting will cause unstable fluctuations in the shock absorption stroke during rotation, which is prone to shock absorption jerking. In order to solve the above technical problems, this invention proposes a cross-slider shock-absorbing wheel hub and mechanical wheel.

[0036] Example 1

[0037] In a typical embodiment of the present invention, such as Figures 1-8 As shown, a cross-slider shock-absorbing wheel hub is proposed, including an inner wheel hub ring 1, a cross-slider mechanism 2, and an outer wheel hub ring 3. The inner wheel hub ring 1, the cross-slider mechanism 2, and the outer wheel hub ring 3 are coaxially arranged when they are in a stationary state.

[0038] The inner ring 1 of the wheel hub does not directly contact the outer ring 3 of the wheel hub. The inner ring 1 of the wheel hub is connected to the outer ring 3 of the wheel hub through the cross slider mechanism 2. The inner ring 1 of the wheel hub is used to fix the connection with the axle, thereby driving the outer ring 3 of the wheel hub to rotate through the cross slider mechanism 2. The inner ring 1, the outer ring 3 of the wheel hub and the cross slider mechanism 2 are connected through the slide rail 204 and the slide groove. The spring on the cross slider mechanism 2 is connected to the inner ring 1 and the outer ring 3 of the wheel hub to realize the shock absorption function.

[0039] like Figure 4 As shown, the inner ring 1 of the wheel hub mainly includes an inner ring body, a first support groove 101 and a first spring lug 102. A central wheel axle through hole for connecting with the wheel axle is provided at the center of the inner ring body. The inner ring body is fixed to the vehicle wheel axle through the central wheel axle through hole and the bolt holes around it, so that the inner ring 1 of the wheel hub rotates synchronously with the vehicle wheel axle.

[0040] The first support slide groove 101 is provided in a pair (i.e., two). The two first support slide grooves 101 are arranged opposite to each other on both sides of the inner ring body. The pair of first support slide grooves 101 are supported and cooperated with the two slide rails 204 of the cross slider mechanism 2. The slider 204 corresponds one-to-one with the first support slide groove 101, that is, a slide rail 204 is slidably provided in one first support slide groove 101. The slide rail 204 is a long column structure, so that the cross slider mechanism 2 and the inner ring 1 of the hub rotate synchronously.

[0041] Two first support grooves 101 are coaxially arranged, so that two slide rails 204 are coaxially arranged. Each first support groove 101 has an inner surface supporting a shock-absorbing spring 202. The shock-absorbing spring 202 is sleeved on the corresponding slide rail 204, so that the slide rail 204 in the first support groove 101 can move back and forth along the direction of the first support groove 101. The shock-absorbing spring 202 undertakes the main shock absorption function.

[0042] Each of the first support slide grooves 101 has a first spring lug 102 on both sides. The first spring lug 102 is fixedly mounted on the inner ring body for connection with the auxiliary support spring 205. The auxiliary support springs 205 on the first spring lugs 102 on both sides of the first support slide groove 101 are connected to the second support limiting slider 208 of the cross-shaped slide rail support leg in the adjacent second support slide groove 301 to undertake the function of auxiliary shock absorption.

[0043] like Figure 8 As shown, the outer ring 3 of the hub mainly consists of an outer ring body and a second support groove 301 and a second spring lug 302 fixedly mounted on the outer ring body. There are two second support grooves 301 and four second spring lugs 302. The two second support grooves 301 are coaxially arranged, and the axes of the two second support grooves 301 are perpendicular to the axes of the two first support grooves 101 to form a cross-shaped axis. The slide rail 204 is slidably mounted in the second support groove 301, and the second spring lug 302 is used to connect with the auxiliary support spring 205.

[0044] Specifically, each of the second support grooves 301 has a second spring lug 302 on both sides. The two support grooves 301 cooperate with the two slide rails 204 of the cross slider structure 2 to complete the transmission of the rotation from the car wheel axle through the inner ring 1 of the wheel hub and the cross slider structure 2 to the outer ring 3 of the wheel hub, so that the inner and outer rings of the wheel hub can rotate synchronously.

[0045] A shock-absorbing spring 202 is supported on the inner surface of the second support groove 301. The shock-absorbing spring 202 is sleeved on the corresponding slide rail 204, so that the slide rail 204 in the second support groove 301 can move back and forth along the direction of the second support groove 301. The shock-absorbing spring 202 undertakes the main shock absorption function.

[0046] Each second support groove 301 has a second spring lug 302 on both sides. The second spring lug 302 is fixedly mounted on the outer ring body for connection with the auxiliary support spring 205. The auxiliary support spring 205 on the second spring lug 302 is connected to the first support limiting slider 206 of the cross-shaped slide rail support leg in the adjacent first support groove 101 to undertake the function of auxiliary shock absorption.

[0047] like Figure 5 As shown, the cross slider mechanism 2 mainly consists of a first fixed seat 201, a shock-absorbing spring 202, a support 203, a slide rail 204, an auxiliary support spring 205, a first support limiting slider 206, a second fixed seat 207, and a second support limiting slider 208.

[0048] Among them, such as Figures 6-7 As shown, a cross-shaped groove is provided on the inner surface of the second fixing seat 207. A cylindrical positioning pin is fixed at each of the four branches of the cross-shaped groove of the second fixing seat 207. One end of the slide rail 204 inserted into the second fixing seat 207 has a cylindrical through hole that mates with the positioning pin. The cylindrical through holes of the four slide rails 204 are inserted into the cylindrical positioning pins of the second fixing seat 207 to mate with each other.

[0049] The first fixing seat 201 has the same shape as the second fixing seat 207. The inner surface of the first fixing seat 201 is also provided with a cross-shaped groove. The first fixing seat 201 and the second fixing seat 207 can be stably assembled with bolts and nuts to ensure the stable positioning of the four slide rails 204. The four slide rails 204 form a cross-shaped slide rail structure. The cross-shaped slide rail contains four perpendicular legs. The first fixing seat 201 and the second fixing seat 207 are fixedly set in the middle position of the cross-shaped slide rail structure.

[0050] Since the cross-shaped slide rail is composed of four slide rails 204, and the four slide rails 204 serve as four legs, for ease of understanding and to demonstrate their function, each leg will be referred to as slide rail 204.

[0051] Four sets of shock-absorbing devices are mounted on four slide rails 204, including shock-absorbing springs 202 and supports 203 mounted on the slide rails 204. Each slide rail 204 has one shock-absorbing spring 202 and two supports 203. The two supports 203 hold the shock-absorbing spring 202 in the middle. The two ends of the shock-absorbing spring 202 are in contact with the inner surfaces of the two supports 203. The outer surfaces of the two supports 203 are in contact with one side surface of the central fixed seat and the inner surface of the corresponding support groove, respectively. That is, the shock-absorbing device consisting of one shock-absorbing spring 202 and two supports 203 is restricted in its position by the adjacent support groove and the central fixed seat.

[0052] Two opposing slide rails 204 are selected to slide and engage with the first support groove 101 on the inner ring 1 of the hub. In this embodiment, the slide rail 204 that engages with the first support groove 101 is called the first slide rail, and the slide rail 204 that engages with the second support groove 301 is called the second slide rail. This allows the cross slider mechanism 2 to rotate synchronously with the inner ring 1 of the hub. The two pairs of damping springs 202 supported between the two allow the cross slider mechanism 2 to reciprocate along the axial direction of the first slide rail and the first support groove 101.

[0053] The other two slide rails 204 (i.e. the second slide rails) together with the corresponding damping devices slide in conjunction with the second support groove 301 of the outer ring of the hub 3 to realize the synchronous rotation of the cross slider mechanism 2 and the outer ring of the hub 3. The two pairs of damping springs 202 supported between the two can make the cross slider mechanism 2 reciprocate along the axis of the second slide rail and the second support groove 301.

[0054] Considering that the cross slider structure 2 will vibrate and rotate inside the outer ring 3 of the wheel hub during the shock absorption process, in order to prevent the slide rail 204 from contacting and interfering with the inner wall of the outer ring 3 of the wheel hub, the two first slide rails that cooperate with the first support slide groove 101 of the inner ring 1 of the wheel hub and the two second slide rails that cooperate with the second support slide groove 301 are designed to have different lengths, and the length of the first slide rail is slightly longer than that of the second slide rail.

[0055] Two first support limiting sliders 206 are supported and cooperated with two slide rails 204 that cooperate with the first support slide groove 101 of the inner ring 1 of the same hub. Specifically, each first slide rail is fitted with a first support limiting slider 206, and the first support limiting slider 206 is located on the outside of the corresponding first support slide groove 101.

[0056] The first support limiting slider 206 has a second spring lug 302 on each side. The first support limiting slider 206 is connected to one end of an auxiliary support spring 205 on each side. The other ends of the two auxiliary support springs 205 connected to the first support limiting slider 206 are connected to the adjacent second spring lug 302.

[0057] Two second support limiting sliders 208 are supported and cooperated with two slide rails 204 that cooperate with the second support slide groove 301 of the outer ring 3 of the same hub. Specifically, each second slide rail is fitted with a second support limiting slider 208, and the second support limiting slider 208 is located on the outside of the corresponding second support slide groove 301 (i.e., on the side away from the shock absorber spring 202).

[0058] The second support limiting slider 208 is adjacent to a first spring lug 102 on each side. The two sides of the second support limiting slider 208 are respectively connected to one end of an auxiliary support spring 205. The other ends of the two auxiliary support springs 205 connected to the second support limiting slider 208 are respectively connected to the adjacent first spring lug 102.

[0059] For ease of understanding, in this embodiment, the auxiliary support spring 205 connected to the first support limiting slider 206 and the second spring lug 302 is referred to as the first auxiliary support spring, and the auxiliary support spring 205 connected to the second support limiting slider 208 and the first spring lug 102 is referred to as the second auxiliary support spring. The first auxiliary support spring is perpendicular to the axis of the first slide rail, the second auxiliary support spring is obliquely arranged, and the second auxiliary support spring forms a set angle with the axis of the second slide rail.

[0060] Considering the overall working stability and load-bearing strength of the shock-absorbing wheel hub, using only four shock-absorbing springs 202 may cause unstable fluctuations in the shock-absorbing stroke during the rotation of the wheel hub, and the load-bearing capacity may not meet many usage conditions. Therefore, using four shock-absorbing springs 202 to undertake the main shock-absorbing function, and adding eight auxiliary support springs 205 to undertake the auxiliary shock-absorbing function, can reduce the unstable fluctuations in the shock-absorbing stroke and improve the load-bearing strength of the wheel hub.

[0061] Example 2

[0062] In another typical embodiment of the present invention, a mechanical wheel is proposed, including a solid rubber tire, which is wrapped around the outer ring 3 of the wheel hub. The solid rubber tire not only further improves the shock absorption capacity of the wheel, but also effectively avoids the phenomenon of air leakage caused by wheel damage, greatly improves the adaptability of the wheel, and reduces the environmental pollution caused by tire recycling.

[0063] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
