Constant velocity joint for vehicle with improved sealing mechanism
A recently granted patent (Publication Number: US11912065B2) discloses a constant velocity joint designed for vehicles. The joint includes a hub housing, a bearing assembly, and a boot with a unique design to prevent foreign substances from entering the bearing assembly. The boot features a boot lip that protrudes towards the knuckle, creating a barrier that bends the movement path of any foreign substances attempting to penetrate the joint. This innovative design helps maintain the integrity and functionality of the constant velocity joint by effectively blocking out contaminants.
Furthermore, the patent details specific dimensions and configurations for optimal performance. For instance, the length of the boot lip is recommended to be between 3 mm to 10 mm, while the distance between the boot and the knuckle should fall within the range of 0.5 mm to 1 mm. Additionally, the constant velocity joint includes features such as a forming portion in the hub housing to press the inner race, a boot seat with a minimum thickness of 5 mm, and bearing seals between the inner race and both sides of the outer race. These precise specifications aim to enhance the durability and longevity of the constant velocity joint, ensuring smooth power transmission and minimal risk of contamination.
