Abstract
Description
Technical Field
[0001] The utility model relates to a multi-angle rotatable structure for preventing water from entering a transmission vent plug, and belongs to the technical field related to automobile transmissions. Background Art
[0002] The transmission is an essential component of the automotive transmission system. As the oil temperature rises during transmission operation, it creates a high pressure inside the transmission, creating a pressure differential with the outside world. This pressure differential must be eliminated through a breather plug to prevent excessive pressure from causing transmission oil leaks and seal damage. Urban dump trucks and sprinkler trucks experience high humidity, and factory spray tests for complete vehicles can lead to poor air exchange inside and outside the transmission breather plug. This can lead to water ingress, causing lubricant emulsification and rusting of components, which can affect transmission shifting. Summary of the Invention
[0003] The technical problem to be solved by the utility model is to address the defects of the existing technology and provide a multi-angle rotatable structure for preventing water from entering the transmission vent plug, so as to eliminate the problems of poor air exchange in the vent plug, water entering the air plug part, resulting in emulsification of lubricating oil and rusting of parts.
[0004] To solve this technical problem, the utility model provides a multi-angle rotatable structure for preventing water from entering the transmission vent plug, including a vent pipe and a right-angle quick-plug connector. The right-angle quick-plug connector includes a shell, connector one and connector two. The shell is an L-shaped tubular structure. Connector one and connector two are respectively arranged at two ends of the shell. An embedded structure is provided between the shell and connector one, and connector one can rotate freely relative to the shell; the connector one is connected to the transmission small cover shell, one end of the vent pipe is inserted into connector two of the right-angle quick-plug connector for fastening, and the other end is fixed to the transmission housing.
[0005] The right-angle quick-plug connector also includes a pressure plate, a bushing, a retaining spring, a gasket, a Y-ring and an O-ring. The inner cavity of the shell is provided with a stepped hole, the Y-ring is arranged at the stepped hole in the inner cavity of the shell, the gasket is arranged on the Y-ring, the pressure plate is arranged on the gasket, and the bushing is arranged between the pressure plate and the shell; an O-ring is arranged between the connector 1 and the shell.
[0006] The pressure plate, bushing, spring clip, joint 1, shell and joint 2 are made of copper-based materials; the shell can operate within the range of -35°C to +120°C.
[0007] The second joint is equipped with a retaining spring. The ventilation tube can be automatically locked when inserted into the two ends of the joint. The ventilation tube can be smoothly taken out by pressing the interfaces at the two ends of the joint.
[0008] The vent pipe is a nylon pipe, and can be selected in different lengths and directions according to different working conditions.
[0009] Beneficial Effects: This utility model effectively ensures good air circulation between the transmission's interior and exterior, achieving consistent pressure inside and outside, preventing condensation caused by uneven temperatures, and circumventing the problem of poor air exchange associated with normally closed vent plugs. The connector can freely rotate relative to the connector housing, allowing the connecting nylon tube to be fixed at any angle, facilitating the layout of the transmission's exterior structure and resolving issues with the vent tube being unable to be fixed due to insufficient space. This utility model is easy to disassemble and offers strong versatility, reducing both assembly, use, and storage costs. BRIEF DESCRIPTION OF THE DRAWINGS
