Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Examples

As shown in fig. 1 to 3, a disc type front axle includes a brake caliper 1, a knuckle 2, a grease fitting 3, and a drag link arm 4, and an i-beam 5;

the brake caliper 1 is mounted on a rod part of the steering knuckle 2 and is positioned right above the steering knuckle 2; the steering knuckle 2 consists of a rod part and two corner connecting ends arranged along the vertical direction, and a lubricating nipple mounting hole 21 for mounting a lubricating nipple 3 is formed in one side, far away from the rod part, of the upper corner connecting end; a straight pull rod arm 4 transversely arranged is arranged below the grease nipple mounting hole 21 on the steering knuckle 2, an avoiding groove 41 is formed in the middle of the straight pull rod arm 4, and the avoiding groove 41 is matched with the grease nipple 3; the I-beam 5 is made of bainite non-quenched and tempered steel and is arranged between the two corner connecting ends of the steering knuckle 2.

In order to install the brake caliper 1 right above the steering knuckle 2, the rod part of the steering knuckle 2 is higher than the conventional design, and enough installation space is reserved; meanwhile, the position of the common grease nipple 3 is the upper part of the corner connecting end of the steering knuckle 2, and if the common grease nipple is arranged on the upper part of the common grease nipple, the common grease nipple can interfere with the brake caliper 1, so that a grease nipple mounting hole 21 is formed in the side surface of the corner connecting end of the steering knuckle 2; in order to avoid interference between the straight pull rod arm 4 and the grease nipple 3, the straight pull rod arm 4 is designed in a light weight mode, the avoiding groove 41 is added, and interference on the grease nipple 3 is avoided while weight is reduced; the upper adjustment is made on the rod part of the steering knuckle 2, so that the position of the central point of the device deviates obliquely, the rim installation distance and the ground clearance are reduced, the steering trapezoid mechanism is changed, the trafficability of the whole vehicle is deteriorated, the neck part of the I-shaped beam 5 is adjusted to ensure that the two important parameters are unchanged, the two important dimensions of the size of the central point of the device and the plate spring installation surface and the distance from the central point of the I-shaped beam 5 are unchanged, and the two important parameters of the rim installation distance and the ground clearance are unchanged.

The brake caliper 1 and the steering knuckle 2 are connected and fixed through a conventional bolt structure, and the I-shaped beam 5 and the steering knuckle 2 are connected and fixed through a conventional pin structure, so that the whole structure of the device is convenient to disassemble and assemble, and subsequent maintenance is facilitated.

The working principle is as follows: firstly, the position of the rod part of the steering knuckle 2 is adjusted upwards, so that when the brake caliper 1 is arranged right above the rod part of the steering knuckle 2, the brake caliper 1 and the steering knuckle 2 are ensured not to generate an interference phenomenon; secondly, the scheme that the traditional grease nipple 3 is arranged above the corner connecting end of the steering knuckle 2 is adjusted to be arranged on the side face of the corner connecting end of the steering knuckle 2, so that the brake caliper 1 is ensured not to interfere with the grease nipple 3, and grease is conveniently filled; next, in order to ensure that the grease nipple 3 and the straight pull rod arm 4 are not interfered, the structure of the straight pull rod arm 4 is adjusted, and an avoiding groove 41 is added; finally, the neck of the I-shaped beam 5 is adjusted to maintain two important parameters of the rim installation distance and the ground clearance unchanged.
