Description

Technical Field

[0001] This utility model belongs to the field of truck flanges, and specifically relates to a truck flange device. Background Technology

[0002] Truck driveshaft connection devices are key mechanical components used to connect driveshafts to gearboxes, drive axles, or other transmission components. Their main function is to efficiently transmit torque and accommodate certain axial, radial, or angular deviations to ensure smooth power transmission. These devices typically use spline sliding connections, flexible couplings, or clamp-type fixation. However, spline connections, flexible couplings, or clamp-type connections have significant drawbacks in practical applications. These drawbacks mainly stem from limitations in their structural design and working principles, leading to vibration and noise in the transmission system when rotating at high speeds or under high torque. This vibration not only reduces driving comfort but may also trigger resonance in other components, accelerating wear on the transmission system. The root cause is that non-rigid connections cannot create a tight metal-to-metal contact surface between the connecting shafts, resulting in small gaps or elastic deformation at the connection points. Therefore, we aim to design a truck flange device to solve this problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a truck flange device to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a truck flange device, comprising: a bushing, wherein a connecting mechanism for connecting two drive shafts is provided on the outer side of the bushing, and a drive shaft is provided inside the bushing;

[0005] The connecting mechanism includes a first flange and a second flange, both of which have through holes. After the first flange and the second flange are fitted together, they are fixedly connected by a bolt assembly. By setting up the connecting mechanism and the bolt assembly, the first flange and the second flange are rigidly connected, which can effectively transmit high torque and avoid slippage or elastic deformation that may occur in flexible couplings. It is suitable for high-power engines or heavy-duty vehicles.

[0006] In a preferred embodiment, the bolt assembly includes a screw rod that is movably sleeved inside a through hole, and a nut is threaded onto the outer side of the screw rod. The bolt connection improves the connection rigidity between the drive shafts.

[0007] In a preferred embodiment, an anti-loosening washer is movably sleeved on the outer side of the screw, and the left side surface of the anti-loosening washer is in contact with the flange.

[0008] As a preferred embodiment, the anti-loosening washer is a nylon insert washer used to increase the frictional resistance of the nut contact surface to prevent the nut from loosening, especially in dynamic environments such as automobiles that are subjected to high-frequency vibration, impact loads and temperature changes.

[0009] In a preferred embodiment, the bushing has a keyway inside and a connecting hole. A connecting screw is movably fitted inside the connecting hole of the bushing. The connecting screw connects the drive shaft to the bushing, preventing axial displacement of the connecting shaft.

[0010] In a preferred embodiment, the number of keyways is several sets to reduce the shear force borne by the connecting screws.

[0011] In a preferred embodiment, a connecting key is integrally fixedly connected to the outer side of the drive shaft. The connecting key is slidably fitted into the inner side of the keyway. The cooperation between the connecting key and the keyway shares the torsional force. The screw mainly plays the role of axial fixation, preventing the screw from deforming or breaking due to shear stress.

[0012] In a preferred embodiment, the drive shaft is provided with an internal threaded connection hole, and a connecting screw is screwed into the internal threaded connection hole.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are:

[0014] 1. By setting up a connection mechanism and bolt assembly, flange one and flange two are rigidly connected, which can effectively transmit high torque and avoid slippage or elastic deformation that may occur in flexible couplings. It is suitable for high-power engines or heavy-duty vehicles.

[0015] 2. The drive shaft and bushing are connected and fixed by setting connecting keys, keyways and screws. The cooperation of the connecting keys and keyways shares the torsional force, and the screws mainly play the role of axial fixation, avoiding deformation or breakage of the screws due to shear stress, thus improving the stability of the connection between the drive shaft and bushing.

[0036] The number of keyways 11 is several sets to reduce the shear force borne by the connecting screws 13.

[0037] The outer side of the drive shaft 3 is integrally fixedly connected with a connecting key 31, which is slidably fitted into the inner side of the keyway 11. The cooperation between the connecting key 31 and the keyway 11 shares the torsional force.
