Description

[Detailed explanation of the invention] This invention uses FF using a hydraulic press machine.
(Front Drive Front Engine) This relates to a disassembly and maintenance jig for a vehicle's front axle, and more specifically, it is a jig for disassembling and maintaining the front axle of a vehicle.More specifically, it is a jig for disassembling and maintaining the front axle of a vehicle, and more specifically, it is a tool that precisely and firmly stabilizes the front knuckle arm of each vehicle type, which has a complex shape, around the rotation axis. This invention relates to a front axle disassembly stand for front-wheel drive vehicles that can support the front axle of a front-wheel drive vehicle.

The front axle hub of a FF car is spline-fitted to the driveshaft, which has an inboard joint inside, so a wheel bearing inner race is press-fitted to the outer periphery, and the wheel bearing outer race is press-fitted into the steering knuckle and connected by a snap spring. It is held in place. When disassembling the front axle hub from the front knuckle arm assembly, a universal puller was used to screw in the front axle hub. Because they could not be disassembled, they were hit with a hammer to give a shock to disassemble them, which caused damage to the wheel bearings and the risk of being hit by the hammer.

The purpose of this invention is to allow the front axle hub to be disassembled safely, quickly, and easily without damaging the wheel bearing due to impact.
Our objective is to provide an axle disassembly stand for FF automobiles.

The feature of this invention is that a plate for fixing the lower arm attachment part of the front knuckle arm is rotatably supported on one leg of the knuckle support base that supports high pressure from a hydraulic press machine, and an insertion hole is provided. A bracket having a cross-shaped support portion at its lower end that suspends the strut bar mounting hole of the front knuckle arm via a pin is slidably fitted into a slot provided on the upper surface of the knuckle support base. ,
By interposing a rod for attaching and detaching the bearing between the hydraulic press machine and the front knuckle arm supported on the knuckle support base, the verticality of the center of the axle hub attached to the steering knuckle arm is ensured, and the hydraulic This system firmly and stably supports the high pressure applied to the knuckle support base via the rod by the press machine, and also enables compatibility with steering knuckles of other vehicle models.

Hereinafter, embodiments of the present invention will be described based on the drawings. FIG. 1 shows the structure of an embodiment of an axle disassembly stand for a front-wheel drive vehicle according to the present invention. A plate 3 having screw holes 3a and 3b for tightening and fixing the lower arm mounting portion 22 of the front knuckle arm 20 is rotatably mounted in the cutout portion 2a via a shaft 4. Supported.

Further, on the upper surface of the knuckle support base 1, there is provided a slot 7 in which a locking hole 7A of the head 6a of the rod 6 and a long hole 7B are continuously formed. A bracket 12 having a support portion 10 whose lower end is shaped like a square is slidably fitted therein. The 〓-shaped support portion 10 has an insertion hole 10A,
10B is bored, and the square support portion 10 connects the strut bar mounting hole 24 of the front knuckle arm 20 and the insertion holes 10A, 10B with the pin 1.
4 through the strut bar mounting hole 2.
4.

In addition, the rod 6 has a large diameter disc-shaped head 6A at one end.
and has a small-diameter annular member 6B at the other end.

In the FF vehicle axle disassembly stand having the above configuration, the lower arm mounting portion 22 of the front knuckle arm 20 is connected to the screw hole 3 of the plate 3.
a, 3b with bolts, and the strut bar mounting hole 24 of the front knuckle arm 20.
and the insertion hole 1 of the square-shaped support part 10 of the bracket 12.
By inserting the pin 14 through 0A and 10B, the strut bar attachment hole 24 is suspended. Then, the front axle hub 30 is disassembled by pressing the steering knuckle coupling portion 26 of the front knuckle arm 20 via the rod 6 using a hydraulic press machine (not shown), and the assembly is carried out by reversing the rod 6 and using it. conduct. Here, the plate 3 rotatably supported by the shaft 4 on the leg part 2 of the knuckle support stand 1 is designed so that it can correspond to the angle change of the lower arm attachment part of the front knuckle arm of each car model, as shown in Fig. 2. The bracket 12 makes a pendulum movement (arrow A), and the bracket 12 is inserted into the slot provided on the knuckle support base 1 so that the strut bar attachment hole 24 of the front knuckle arm 20 is aligned with the insertion holes 10A and 10B made in the support part 10. It functions to slide the portion 7 (arrow B).

According to this embodiment, it becomes possible to use a hydraulic press machine which has not been available in the past, and it becomes possible to carry out disassembly work quickly and safely. Furthermore, compared to the conventional disassembly work in which a shock is applied using a dedicated disassembly tool, this embodiment utilizes static high pressure from a hydraulic press, so there is no damage to the components of the front knuckle arm.

As explained above, in the present invention, the plate for fixing the lower arm attachment part of the front knuckle arm is rotatably supported on the leg on one side of the knuckle support base that supports high pressure from a hydraulic press machine, and the plate that fixes the lower arm attachment part of the front knuckle arm is rotatably supported. A bracket having a cross-shaped support portion at its lower end that suspends the strut bar mounting hole of the front knuckle arm through a drilled pin is slidably fitted into a slot provided on the upper surface of the knuckle support base. At the same time, the present invention has a structure in which a rod for attaching and detaching the bearing is interposed between the hydraulic press machine and the front knuckle arm supported by the knuckle support base. It becomes possible to use a hydraulic press machine, allowing quick and safe disassembly and assembly work without damaging the front knuckle arm components.
