Description

Front brake with strut assembly

technical field

The utility model relates to an automobile chassis system, in particular to a front brake belt sliding column assembly.

Background technique

In the automobile chassis system, the strut assembly belongs to the transmission system, which mainly relieves the vibration of the ground to the vehicle and ensures the stability and comfort of the vehicle. The front brake assembly belongs to the brake system and mainly plays the role of stopping the moving vehicle.

In the vehicle layout, the strut assembly is installed on the side of the steering knuckle. When the car is running on an uneven road or subjected to a heavy load impact, the buffer block, spring, etc. generate a large axial force, which acts on the strut, and the joint between the steering knuckle and the strut assembly is subjected to a huge test.

In the current structure, the strut assembly and the steering knuckle are tightly connected with the steering knuckle damping arm by two sets of bolts and nuts through the lifting lug welded on the outer cylinder of the strut. That is, two sets of bolts pass through the strut lug and the knuckle shock arm hole, securing the two. The assembly requirements are high and difficult, and it is necessary to align the two holes at the same time, and it is difficult to assemble when the distance between the holes of one part is out of tolerance; there is a gap between the bolt and the steering knuckle hole and the lug hole, which affects the installation posture of the sliding column assembly, and the positioning is difficult .

The sliding column assembly generates a large axial force when it is working, and directly acts on two groups of bolts and nuts, and its strength often cannot meet the requirements of the axial force it can bear. Once the connection part fails, the sliding column assembly will lose its support and collapse, and the consequences will be disastrous.

Contents of the invention

The utility model aims to solve the above-mentioned shortcomings of the prior art, and provides a front brake with sliding column assembly which is convenient for assembly and disassembly, good in positioning, reliable in positioning, and strong in bearing capacity.

The technical scheme adopted by the utility model to solve the technical problems: the front brake with a spool assembly is composed of a front brake assembly and a spool assembly, wherein the front brake assembly is equipped with a steering knuckle, and is characterized in that: The steering knuckle cooperates with the outer cylinder of the strut assembly through the slotted hole at the front end, and is fixedly connected by the pivot bolt and the self-locking nut.

The middle of the outer cylinder of the sliding column assembly is provided with a limiting boss, and the outer cylinder of the sliding column assembly is also provided with a ring-shaped limiting bulge.

The beneficial effects of the utility model are: 1. The gap between the steering knuckle and the sliding column assembly is matched with the outer cylinder of the sliding column through the slotted hole on the steering knuckle, which has the advantages of convenient assembly and disassembly; 2. The setting of the clearance fit is reasonable The matching tolerance can ensure the installation posture of the sliding column assembly on the whole vehicle, and has the advantage of good positioning; 3. The positioning is reliable through the limitation of the limit boss and the limit bulge; 3. The axial direction generated when the vehicle is running The force mainly acts on the round hole of the steering knuckle. The steering knuckle is cast iron and has a strong bearing capacity.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

Referring to the accompanying drawings: the utility model is composed of a front brake assembly 1 and a sliding column assembly 2, wherein the front brake assembly 1 is equipped with a steering knuckle 1-1, and the steering knuckle 1-1 passes through the slotted round hole 1-2 at the front end The clearance fit with the outer cylinder of the strut assembly 2, and at the same time, a reasonable fit tolerance is set for the clearance fit, which can ensure that the installation posture of the strut assembly 2 on the vehicle has the advantage of good positioning. And through the limit boss 2-1 and the limit drum 2-2 on the outer cylinder of the sliding column assembly 2 to limit the position, the limit boss 2-1 is aligned with the steering knuckle 1-1 slotted round hole 1 during assembly -2 is slotted and inserted into it to limit the position in the circumferential direction; after being assembled with the steering knuckle 1-1, the limit bulge 2-2 is blocked above the slotted round hole 1-2 of the steering knuckle 1-1, Play the role of axial limit. After the front brake assembly 1 and the strut assembly 2 are assembled in place, they are fixedly connected by the pin bolt 3 and the self-locking nut 4 .

In addition to the above embodiments, the utility model can also have other implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the utility model.
