Steering axle and vehicle with same

Abstract

The invention provides a steering axle and a vehicle with the same. The steering axle comprises an axle (11), a steering knuckle (12), a main pin (14), a lining (13) and a sealing device, wherein the main pin (14) penetrates through an ear part of the steering knuckle (12) and a fist part of the axle (11) to connect the axle (11) with the steering knuckle (12); the lining (13) is arranged between the main pin (14) and a pin hole in the ear part, which is matched with the main pin (14); both the upper end part and the lower end part of the lining (13) are cut through; the periphery of the main pin (14) is provided with a flange (141) which is positioned between the fist part of the axle (11) and a corresponding end face of the lining (13); and the sealing device is arranged between the peripheral surface of the flange (141) and the pin hole. Lubricating grease for lubricating the main pin is sealed by the flange and the sealing device, so that too much lubricating grease is prevented from flowing into a gap between the steering knuckle and the axle along an oil groove formed in the lining.

Description

technical field [0001] The invention relates to the field of vehicles, in particular, to a steering axle and a vehicle with the same. Background technique [0002] There are two main forms of vehicle steering axle or steering drive axle kingpin: one is the integral kingpin structure, such as figure 1 Shown, kingpin 5 is a whole, bearing is housed between steering knuckle 2 lower lugs and axle 1 fist. There is an appropriate gap △ between the upper ear of the steering knuckle 2 and the fist of the wheel shaft 1. The gap is relatively small, generally 0.05-0.15, and it is guaranteed by the optional adjustment gasket 4. In order to reduce wear and tear, the bushing 3 is pressed into the pin hole of the steering knuckle 2, and the lubricating oil groove on the bushing 3 is cut through at the upper end, and the lubricating grease is injected with the grease nipple installed on the steering knuckle 2 or the king pin cover and other accessories Lubricate kingpin 5. There are two...

Problems solved by technology

[0004] Disadvantages in the prior art: the lubricating oil groove on the bushing 3 is only cut through at the upper end. During the relative movement between the steering knuckle 2 and the fist part of the wheel shaft 1, the gap between the upper plane of the steering knuckle 2 and the fist part of the wheel shaft 1 is relatively small. Small, it may cause wear due to dry friction between the two contact surfaces without proper lubrication, causing the gap to increase during vehicle use, thus adversely affecting the performance of the steering axle

As the gap increases during the dynamic use of the vehicle, the wear of the kingpin 4 (or upper kingpin 5') at the junction with the steering knuckle 2 will increase, which will also adversely affect the performance of the steering axle and cause lubrication. oil loss
