Embodiment 1

[0029] Embodiment one, see figure 1 , a vehicle front axle with a convex bottom casting structure, including a cross bar 5. Two ends of the cross bar 5 are respectively provided with a vehicle frame supporting portion 1 . The frame supporting part 1 is directly formed on the cross bar. Two ends of the cross bar 5 are respectively connected with a cantilever 2 . The cross bar 5 and the cantilever 2 are integrally structured. The cross bar 5 and the cantilever 2 are forged structures, that is, the cross bar 5 , the cantilever 2 and the vehicle frame support part 1 are all forged as one. The upper surface of the cross bar 5 is provided with an escape groove 59 passing through the front and rear surfaces of the cross bar. The escape groove 59 is located between the two frame support parts 1 . The lower surface of the cross bar 5 is provided with a convex strip 56 . The protruding strip 56 is aligned with the escape groove 59 . The front and rear surfaces of the cantilever 2...

Embodiment 2

[0032] Embodiment two, the difference with embodiment one is:

[0033] see Figure 4 , There are two bearings 23 inside the kingpin hole 22 . A first gear 24 and a second gear 25 meshed together are arranged between the two bearings 23 . The first gear 24 is coaxial with the bearing 23 . The second gear 25 is rotatably connected with the cantilever 2 through the short shaft 251 .

[0034] see Figure 5 , the first gear 24 is provided with a refueling mechanism 8 . The number of refueling mechanisms 8 is equal to the number of teeth of the first gear 24 .

[0035] see Figure 6 ,, The refueling mechanism 8 includes an oil outlet 81, an air supply port 82, a sealing head 83, a first spring 84, a cylinder 85 and a piston 86. The oil outlet 81 and the air supply port 82 of the same fueling mechanism are arranged on the tooth top 241 of the same tooth of the first gear 24, and the tooth top of the same tooth is only provided with an oil outlet and an air supply port of the f...

Embodiment 3

[0040] Embodiment three, the difference with embodiment two is:

[0041] see Figure 8 , two ends of the cross bar 5 are respectively provided with an installation cavity 55 (only the installation cavity at the left end is shown in the figure). The installation cavity 55 is located between the frame support part 1 and the suspension arm 2 . The upper and lower walls of the installation cavity 55 are provided with shock absorbing structures 3 .

[0042] see Figure 9 The damping structure includes a lock nut 35 , an adjusting nut 34 , a core sleeve 33 , a butterfly spring 32 with a small end facing the core sleeve, and a mounting plate 31 that are sequentially abutted together in the vertical direction. An adjusting screw 36 is fixedly connected to the mounting plate 31 . The adjusting screw rod 36 is screwed together with the adjusting nut 34 and the locking nut 35 after passing through the butterfly spring 32 and the core sleeve 33 . The core sleeve 33 is provided with a...

Abstract

The present invention relates to a front axle of an automobile. An automobile front axle with a convex bottom casting structure, comprising a cross bar and two cantilever arms, a frame support portion is provided at both ends of the cross bar, and a cantilever is connected to each of the two ends of the cross bar. The cantilever is provided with a king pin hole, and the upper surface of the cross bar is provided with an avoidance groove passing through the front and rear surfaces of the cross bar. The avoidance groove is located between the two frame support parts, and the small surface of the cross bar is provided with The convex line, the convex line is aligned with the avoidance groove, the cross bar and the cantilever are integrated, the cross bar and the cantilever are forged structures, and the front and rear surfaces of the cantilever are respectively provided with a steering protection block. The invention provides an automobile front axle with a cantilever cross bar integrated structure and a convex bottom casting structure with good anti-steering impact ability, which solves the low yield rate of the existing front axle and improves the resistance by increasing the cross section of the cantilever. The problem of high fuel consumption caused by impact capability.

Description

technical field [0001] The invention relates to an automobile front axle, in particular to an automobile front axle with a convex bottom casting structure. Background technique [0002] The front axle of the car, also known as the front axle, is used to install the front wheels, support the weight of the front of the car, and connect with the frame with the front suspension. In Chinese patent application number 2011201792654, the authorized announcement date is December 28, 2011, and promptly discloses a kind of automobile front axle of existing structure in the patent document of name " automobile front axle assembly ". The front axle of the automobile comprises a cross bar and two cantilever arms. A vehicle frame supporting part is respectively arranged at two ends of the cross bar, and a cantilever is respectively connected to the two ends of the cross bar. The cantilever is provided with a king pin hole. During use, the steering knuckle is connected with the front axle ...
