Description

Band for fastening boot of a vehicle {Band for connecting boot}

The present invention relates to a band for fastening a boot of a vehicle. More specifically, the use of the material of the band as a shape memory alloy is less time consuming and relatively easy to work, and even if diameter reduction occurs due to deterioration of the fastening part. The present invention relates to a band for fastening a boot of a vehicle capable of recovering a shape and continuously preventing leakage.

Generally, a joint is for transmitting rotational power (torque) to a rotation shaft having different angles of rotation axis. In the case of a propulsion shaft having a small power transmission angle, a hook joint, a flexible joint, or the like is used. A constant velocity joint is used.

Since the constant velocity joint can transmit power smoothly at a constant speed even when the angle of intersection between the drive shaft and the driven shaft is large, it is mainly used for the axle shaft of the independent suspension type front wheel drive vehicle, and the engine side (inboard side) Type joint, and the tire side (outboard side) around the shaft is made of a ball type joint.

1 is a cross-sectional configuration diagram of a general constant velocity joint, FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1, and FIG. 3 is an external configuration diagram of a general constant velocity joint.

As shown in FIGS. 1 to 3, a general constant velocity joint configuration includes a tripod-type joint on an engine side (inboard side) around a shaft 1, and a wheel side (about a shaft 1). Outboard side) consists of a ball type joint.

The structure of the tripod type joint, which is installed on the engine side (inboard side) around the shaft 1, transmits the rotational power of the engine (not shown) and has a track groove formed therein. And a shaft 1 which is rotated by receiving the rotational power of the housing 2, and is connected to one end of the shaft 1 to connect the housing 2 and the shaft 1 to the housing 2. Spider 3 is installed inside the three trunnions (3a) is inserted into the track groove, the inner roller (6) is installed on the outer peripheral surface of the trunnion (3a) of the spider (3), A needle roller 5 installed on an outer circumferential surface of the inner roller 6, an outer roller 4 installed on an outer circumferential surface of the needle roller 5 to reduce friction between the housing 2 and the shaft 1; The lid is assembled to the lower portion of the outer roller 4 in order to prevent the outer roller 4 from being separated. An inner clip 8, a boot 10 having one end connected to the housing 2 and an end connected to the shaft 1, and clamping bands 11 and 12 for fixing the boot 10, respectively. It is made, including.

The configuration of the ball-type joint provided on the tire side (outboard side) centering on the shaft 1 is connected to one end of the shaft 1 that is rotated by receiving the rotational power of the tripod type constant velocity joint. An inner race 15, an outer race 13 installed outside the inner race 15, a ball 16 for transmitting rotational power of the inner race 15 to the outer race 13, and A cage 14 for supporting the ball 16, a sensor ring 17 installed outside the outer race 13, and one end connected to the shaft 1 are connected to the outer race 13. Boot 18 is connected to one end and the clamping band (19, 20) for fixing the boot (18).

A damper 21 is installed in the middle of the shaft 1 using bands 22 and 23 and the damper 21 has a structure in which a mass is installed therein.

The operation of a constant velocity joint according to the above construction is as follows.

When the rotational power output from the engine (not shown) is transmitted to the housing 2 via a transmission (not shown), the housing 2 is rotated. The rotational power of the housing 2 is the outer roller 4, It is transmitted to the spider 3 through the needle roller 5 and the inner roller 6 to rotate the shaft 1 connected to the spider 3. In addition, the rotational power of the shaft 1 is transmitted to the outer race 13 through the inner race 15 and the ball 16 to rotate the wheel (not shown) connected to the outer race 13.

In this case, in the tripod type joint provided on the engine side (inboard side) with respect to the shaft 1, the outer roller 4 is associated with the outer roller 4 by sliding the inside of the track groove of the housing 2. As the rotation angle of the shaft 1 is changed, it becomes sharp according to the displacement of the vehicle, and in the ball type constant velocity joint provided on the wheel side (outboard side) around the shaft 1, the ball 16 As a result, the rotation angle of the outer race 13 is changed, and thus the angle of the outer race 13 is cut according to the displacement of the vehicle.

In addition, the boot 10 on the side of the tripod type joint and the boot 18 on the side of the ball type joint enclose the outside of the tripod type joint and the ball type joint, respectively, so that the tripod- To prevent damage by the material.

In addition, when the torque output from the engine transmits torque to the wheel side through the transmission 1 through the transmission, unbalanced rotation occurs at any rotational speed in the shaft 1 rotating at a high speed. Such unbalanced rotation is preferable Causing undesirable vibrations and adversely affecting the operation of the drive system. In order to suppress undesired vibration caused by such an unbalanced rotation, the damper 2 installed in the middle portion of the shaft 1 has a buzzing noise due to the harmful vibration frequency occurring at the shaft 1 during the high speed rotation of the shaft 1. to prevent booming noise.

On the other hand, the boot 10 on the tripod type joint side and the boot 18 on the ball type joint side are fixed by a boot fastening band. However, a conventional boot fastening band is time-consuming and relatively difficult to work with. In addition, there is a problem that leakage occurs when the diameter reduction caused by deterioration in the fastening portion.

An object of the present invention is to solve the conventional problems as described above, by using the material of the band as a shape memory alloy is less time-consuming and relatively easy to work as well as diameter reduction due to deterioration in the fastening portion Even if it is possible to recover the shape to continue to prevent leakage, to provide a boot fastening band of the vehicle.

As a means for achieving the above object, the configuration of the present invention is a boot fastening band for fastening a boot on the tripod type joint side and a ball on the ball type joint side, wherein the boot fastening band is shaped as a material of the boot fastening band. It is preferable to use a memory alloy.
