The invention provides a driving-steering front axle. The driving-steering front axle comprises a steering knuckle, a front axle housing, a first king pin structure, a second king pin structure, a steering trapezoidal arm and a cover plate. One side of the front axle housing is rotatably connected with a first side of the steering knuckle through the first king pin structure, and the other side of the front axle housing is rotatably connected with a second side of the steering knuckle through the second king pin structure; the first king pin structure comprises a first connecting king pin and a metal lining outer ring, the first connecting king pin comprises a first connecting column-shaped section and a second connecting column-shaped section which are coaxially arranged, and the diameter of the first connecting column-shaped section is larger than the diameter of the second connecting column-shaped section; and the metal lining outer ring is mounted on the first connecting column-shaped section in a sleeving mode and in running fit with the first connecting column-shaped section, the second connecting column-shaped section is in interference fit with a first mounting hole of the front axle housing, and the outer wall surface of the metal lining outer ring is in interference fit with a first pin hole of the steering knuckle. According to the driving-steering front axle, connection of the steering knuckle and the front axle housing is achieved, the abrasive resistance of the first king pin structure is good, and the reliability is high.
Description
technical field [0001] The invention relates to the technical field of vehicle axles, in particular to a steering drive front axle. Background technique [0002] The existing front axle is usually a steering front axle, which includes a steering knuckle and an I-beam, such as figure 1 and figure 2 As shown, when connecting, an integral kingpin 13 passes through the upper kingpin hole of the steering knuckle 11, the pin hole of the I-beam 12, and the lower kingpin hole of the steering knuckle 11, and the lock pin 14 is connected with the kingpin The gap 15 on the pin 13 is locked tightly, and the steering knuckle 11 rotates around the main pin 13 to realize the steering function. [0003] However, the steering drive front axle is widely used at present, the I-beam is replaced by the front axle housing, the half shaft needs to pass through the front axle housing, and the half shaft needs to be able to rotate when the vehicle is running, so the existing integral main Pin ca...
