A vehicle steering active arm

Abstract

The invention belongs to the technical field of driving arms, particularly discloses a vehicle steering driving arm which comprises a driving mounting head, a connecting plate, a pressurizing pump, anair inlet joint, an oil tank, an oil outlet joint, a three-way pipe, a hose, an oil injection head mounting plate, a driven mounting head, a one-way valve, a wear-resistant ring and an oil injectionhead, a mounting column and an oil storage hole. The vehicle steering driving arm comprises an oil injection mechanism, lubricating oil can be periodically injected into the wear-resistant ring at theconnection part between the device and the central connecting rod, the friction generated between the central connecting rod and the wear-resistant ring is reduced, the heat generated by the frictionis reduced, the friction resistance is greatly reduced, steering is facilitated, and the service life of the device is prolonged. The chromium carbide wear-resistant ring is arranged in the hollow groove of the driven mounting head connected between the vehicle steering driving arm and the central connecting rod, and the inner wall of the chromium carbide wear-resistant ring is provided with a plurality of oil storage holes. Lubricating oil can be stored in the oil storage holes, reducing the injection times of the lubricating oil, being beneficial to lubrication and heat dissipation when thedevice is used, and prolonging the service life of the device.

Description

technical field [0001] The invention belongs to the technical field of active arms, in particular to a vehicle steering active arm. Background technique [0002] With the continuous development of science and technology, cars are becoming more and more intelligent, and the safety and handling of vehicles have been greatly improved. The steering mechanism of a vehicle is an indispensable mechanism for controlling a vehicle. The first output arm is connected with the central link through the steering active arm, and then the central link drives the driven control arm to achieve the purpose of steering. [0003] However, most of the existing steering active arms of vehicles do not contain an oil injection mechanism. During use, the contact between the steering active arm and the central link generates friction and heat, which not only increases the friction of steering, but also accelerates the wear of the device, which is not conducive to To ensure the service life of the dev...

Problems solved by technology

[0003] However, most of the existing steering active arms of vehicles do not contain an oil injection mechanism. During use, the contact between the steering active arm and the central link generates friction and heat, which not only increases the friction of steering, but also accelerates the wear of the device, which is not conducive to To ensure the service life of the device, and after the existing steering active arm and center connecting rod are installed and manually injected lubricating oil, the lubricating oil will drip due to the action of gravity, and the lubrication time is short. Frequent manual lubricating oil is required to ensure the device Lubricity, there are certain deficiencies
