Description

Technical Field

[0001] This utility model relates to the field of motor performance testing technology, specifically to an adjustable angle automotive universal coupling. Background Technology

[0002] Adjustable angle automotive universal couplings are mechanical transmission devices used to connect power transmission components with axial misalignment, allowing dynamic adjustment between the input and output shafts within a certain angle range. Their basic structure typically includes a cross shaft, bearing housing, flange fork, and angle adjustment mechanism, achieving multi-directional angle compensation through the hinged design of the cross shaft. These couplings must balance torque transmission efficiency with angular adaptability during transmission, reducing friction loss through rolling or sliding bearings and employing a sealing structure to prevent contaminant intrusion. Their performance indicators mainly include maximum operating angle, torque capacity, speed limit, and durability, requiring the matching of rigid or elastic materials based on the application scenario. Commonly found in multi-axle steering systems, transfer case power distribution, and independent suspension drive axles, they maintain continuous power transmission under complex road conditions and reduce the impact of mechanical vibration on the transmission system. Design must comprehensively consider space constraints, load characteristics, and environmental tolerance to ensure reliability and safety under dynamic operating conditions.

[0003] For example, the high-life universal joint coupling for automobiles disclosed in patent announcement number CN220850460U includes a coupling body with a protective structure installed on it. The protective structure includes a fixing ring. Two fixing rings are fixedly connected to both ends of the coupling body in a parallel and symmetrical relationship. Positioning rings are detachably connected to both fixing rings. A locking block is detachably connected between the fixing rings and the positioning rings. Multiple locking grooves are provided in the fixing rings. The locking block engages with the locking grooves, and a protective strip is fixedly connected to the locking block. This patent mentions that it can protect the sliding parts of the universal joint coupling, preventing wear and damage to the sliding parts, thereby improving the service quality and life of the universal joint coupling.

[0004] However, the universal joints in this patent and existing automotive couplings cause wear at the connection points during use because the drive shaft drives the coupling to swing. Replacing these couplings after wear is costly, and the couplings are also limited in use due to the different bore sizes when connected to drive shafts of different diameters. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable-angle automotive universal coupling to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable-angle automotive universal coupling includes a connecting shaft, a locking block fixedly installed on one side of the connecting shaft, a universal mechanism provided on one side of the connecting shaft, and an assembly mechanism provided on the outside of the connecting shaft. The universal mechanism includes a first universal clamp, a connecting shaft fixedly installed on one side of the first universal clamp, first bearings fixedly installed on both sides of the first universal clamp, and a cross shaft fixedly installed inside the first bearing.

[0008] Preferably, the universal mechanism further includes a second universal clamp, on both sides of which a second bearing is fixedly installed, and a cross shaft is fixedly installed inside the second bearing.

[0009] Preferably, a mounting plate is fixedly installed on the side of the second universal clamp away from the cross shaft, and the mounting plate has mounting holes.

[0010] Preferably, the assembly mechanism includes a connecting clamp, a connecting shaft is fixedly installed inside the connecting clamp, a slot is opened on one side of the connecting clamp, and a locking block is fixedly installed inside the slot.

[0011] Preferably, clamping plates are fixedly installed at both ends of the connecting clamp, clamping holes are provided on the clamping plates, locking screws are fixedly installed in the clamping holes, and locking nuts are screwed onto the locking screws.

[0012] Preferably, a connecting plate is fixedly installed on one side of the connecting clamp, the connecting plate has a connecting hole, a connecting screw is fixedly installed in the connecting hole, and a connecting nut is screwed onto the connecting screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This adjustable-angle automotive universal coupling connects the drive shaft and the universal structure via a connecting clamp, which can prevent wear and damage between the universal structure and the drive shaft, and also reduces the cost of replacing the connecting clamp assembly.

[0015] 2. This adjustable-angle automotive universal coupling has two sets of interchangeable connecting clamps. Therefore, when the diameter of the drive shaft is different from that of the universal structure, it can still be connected through the connecting clamp assembly, thus avoiding the limitation of the overall universal structure.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0023] An adjustable-angle automotive universal coupling includes a connecting shaft 101, a locking block 102 fixedly installed on one side of the connecting shaft 101, a universal mechanism 103 provided on one side of the connecting shaft 101, an assembly mechanism 104 provided on the outside of the connecting shaft 101, the universal mechanism 103 including a first universal clamp 105, the connecting shaft 101 fixedly installed on one side of the first universal clamp 105, first bearings 201 fixedly installed on both sides of the first universal clamp 105, and a cross shaft 202 fixedly installed inside the first bearings 201.

[0024] With the above scheme, the connecting clamp can be installed through the connecting shaft, and the locking block can limit the movement so that the connecting shaft can rotate after the connecting clamp is installed. The rotation of the connecting shaft can drive the first universal clamp to rotate, the first bearing can drive the cross shaft to rotate, and the cross shaft can drive the second universal clamp to rotate.

[0025] In this embodiment, preferably, the universal mechanism 103 further includes a second universal clamp 203, on both sides of the second universal clamp 203, a second bearing 204 is fixedly installed, and a cross shaft 202 is fixedly installed inside the second bearing 204.

[0026] With the above scheme, the second universal clamp, driven by the cross shaft and rotated by the first universal clamp, can cause the mounting plate to rotate the wheel. The second bearing causes the cross shaft and the second universal clamp to rotate together, and the rotation between the cross shaft and the first universal clamp allows for universal adjustment between the first and second universal clamps.

[0027] In this embodiment, preferably, the second universal clamp 203 is fixedly mounted on the side away from the cross shaft 202 with a mounting plate 205, and the mounting plate 205 has a mounting hole 206.

[0028] With the above solution, the mounting plate and the wheel can be connected through the second mounting hole, thereby causing the wheel to be driven to rotate.

[0029] In this embodiment, preferably, the assembly mechanism 104 includes a connecting clip 301, in which a connecting shaft 101 is fixedly installed, and a slot 302 is provided on one side of the connecting clip 301, in which a card block 102 is fixedly installed.

[0030] The above solution allows the connecting shaft to be clamped by a connecting clamp, and the mounting of the locking block by a slot ensures that the connecting shaft remains in a limited position after installation, thereby generating rotation.

[0031] In this embodiment, preferably, clamping plates 303 are fixedly installed at both ends of the connecting clamp 301, clamping holes 304 are provided on the clamping plates 303, locking screws 305 are fixedly installed in the clamping holes 304, and locking nuts 306 are screwed onto the locking screws 305.

[0032] With the above solution, the clamping plate can be fixed to the connecting clamp on the connecting shaft by installing a locking screw and a locking nut in the clamping hole, and at the same time, another set of connecting clamps can be fixed to the transmission shaft.

[0033] In this embodiment, preferably, a connecting plate 401 is fixedly installed on one side of the connecting clamp 301, a connecting hole 402 is provided on the connecting plate 401, a connecting screw 403 is fixedly installed in the connecting hole 402, and a connecting nut 404 is screwed onto the connecting screw 403.

[0034] The above solution allows for the assembly of two sets of connecting clamps by connecting the connecting screw through the connecting hole and connecting nut, thereby enabling the drive shaft to be assembled with the universal joint structure.

[0035] In this embodiment of the adjustable-angle automotive universal coupling, the user connects the mounting plate 205 to the wheel through the mounting hole 206 to complete the assembly of the universal structure. Then, the user installs the connecting clip 301 on the connecting shaft 101, causing the locking block 102 to engage in the locking groove 302. At this point, the user secures the connecting clip 301 to the connecting shaft 101 by connecting the locking screw 305 through the locking hole and the locking nut 306. After securing, the user connects another set of connecting clips 301 to the automotive drive shaft. Finally, the connecting screw 403 passes through the connecting hole 402 and the connecting nut 404. The connection allows the drive shaft and the universal joint 103 to be assembled. After assembly, when transmission is performed, the drive shaft drives the connecting shaft 101 to rotate through the connecting clamp 301, causing the first universal clamp 105 to rotate. When the first universal clamp 105 rotates, the cross shaft 202 drives the second universal clamp 203 to rotate, thereby causing the first universal clamp 105 to drive the mounting plate and the wheel to rotate. During the transmission process, the cross shaft 202 rotates inside the first bearing 201 and the second bearing 204 respectively, thus allowing the first universal clamp 105 and the second universal clamp 203 to achieve omnidirectional rotation through angle adjustment.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
