Description

SAFETY CONNECTION DEVICE FOR AN ANTI-SKIDDING SYSTEM OF WHEELS OF VEHICLES}

The invention is intended for a safety connection device (or connection guarantee device) for an anti-skid system of a vehicle wheel, in particular for an anti-slip system in the form of a support bar which is elastically connected to the outer ring of the wheel.

Some antiskid systems of this kind are known from EP 496 702 and CH 689 206.

Particularly effective devices are those disclosed in PCT / IB03 / 02898 of the same applicant, which are incorporated herein by reference in order to provide a comprehensive understanding of the system.

In these known devices, a coupling body and a connecting device are included in a system for fixing a support bar to a wheel, with a bar attached to the coupling body, and the coupling body is fixed to one outer ring bolt through the connecting device.

In particular, it utilizes the relative axial movement between the conical bush and the socket-shaped body (in some cases, external or internal) to clamp the wheel bolts, clamping the outer ring bolts as the bush deforms and compresses elastically. All.

To achieve this relative movement, a screw-to-thread coupling device is used, which achieves the desired relative axial movement at the proper axial rate through the relative rotation of the two components.

1 shows an application example according to the technique introduced in PCT / IB03 / 02898. As can be seen here, the bush-shaped body 1 with the deformable conical clamping flap 1a moves inside the socket 2 whose inner surface is also partly conical. The bush-shaped body 1 is fastened on the head of the bolt B and is connected to a screw 3 which engages with the rotary handle 4 through the bottom of the socket 2. The translation of the threaded connecting rod 3 is determined by the rotation of this rotary handle 4, which abuts against the coupling body 2a and is thus interconnected with the socket 2, thereby the socket 2 The body (1) associated with it also moves. The coupling body 2a connected to the socket 2 is connected to the connecting rod 5, and the U-shaped bracket 5a is installed on the coupling rod 5 so as to move freely, thereby allowing the bar of the anti-slip system (not shown). Subtype structures are linked. In particular, the bar type connection of the anti-slip system consists of a chain (6).

The rod 5 has its sole purpose to move the attachment point of the chain (ie anti-skid system) from the eccentric position of the bolt B to the central axis of rotation C of the vehicle wheel.

Nevertheless, such an adjustment does not always accurately detect whether the user has properly tightened the handle 4, and thus is not sure that the bolt B is effectively connected.

Therefore, the engagement that allows the bush 1 to engage on the bolt B may not be suitable to withstand the pressure exerted from the chain 6 while the vehicle is moving. In rare cases, this may undesirably cause the bush to be detached from the bolt B, thereby completely separating the coupling device from the wheel.

To eliminate this risk, there is a need for a connection device that ensures better safety while maintaining the simple installation of known technical systems.

Therefore, the object of the present invention is to provide a safety for an anti-slip system, to minimize the risk of accidental detachment while allowing convenient and effective clamping of the fixing elements of the outer ring, in order to solve the inconveniences that may sometimes occur in the known art. It is to provide a connection device.

As the essential features are described in the appended claims, the above object is achieved through a coupling device associated with an anti-slip system according to the present invention.

In particular, there is provided a connecting device of an anti-skid system, including a fixed part of a vehicle wheel according to the first aspect of the present invention, comprising a coupling body interconnected with a centering rod, on which the coupling part moves, and the coupling body is threaded. The connecting rod is engaged with the fixed part via a rotating handle acting on the connecting rod, which is passed through the handle and the engaging body and connected to a threaded auxiliary hole formed at the head of the fixed part, the handle being connected via a screw-to-thread coupling. It moves longitudinally on the connecting rod to push the coupling body toward the head of the fastening part.

According to a preferred embodiment of the present invention, there is a clamping device consisting of a bushing body and a bush having a flexible clamping element at its center between the coupling body and the parts of the wheel, the socket-shaped body being movable with respect to the connecting rod. It is assembled so that it is combined with the hexagonal head of the fixed part.

According to a further advantage of the present invention, the connecting rod of the connecting device is provided with an operation handle, which is located at the opposite end of the side with the fixed part, and the operation handle is disposed between the handle and the coupling body.

According to yet another aspect of the present invention, there is provided a complete vehicle wheel anti-skid system, comprising a rolling track, several bars supporting the track on the wheel, and the connection device specified above, with threaded auxiliary holes. A fixed part is also included, which replaces the standard fixed part placed on the wheel of the vehicle where the anti-slip system is installed.

The details of other features and advantages of the present invention are more apparent in the following examples and in the accompanying drawings of some preferred embodiments.

The present invention adopts a connecting rod with a handle 101a and a handle 110 at the same time. On the one hand, unwanted disconnection from the wheel is achieved by fixing the connecting device to the threaded hole of the bolt 114 or the nut 111. It does not happen-it can be securely engaged, and on the other hand, the handle can be used to securely and securely fasten the connection device, so that the bar device of the anti-slip system works stably and effectively.

The connecting device of the anti-skid system (simply snow chain) with the fastening parts of the vehicle wheels has a coupling body 100, a lock connecting rod 101 passing through a hole in the coupling body, and a thread of the coupling body 100. It is comprised by the connecting rod 102 inserted in the formed hole 100a.

At the end of the connecting rod 102 there is a thread to be connected to the hole (100a), through which the coupling body 100 is coupled with each other.

U-shaped bracket 103 and the anti-collision sphere 104 may be made of a plastic material and is fitted over the rod (102). The sphere 104 has a conical hole 104a into which the head 102a of the rod 102 enters. This prevents the risk that the sphere 104 forms the distal end of the rod 102 (as shown in FIGS. 5 and 6) so that the head 102a of the rod 102 does not protrude and harm the user. do.

The bracket 103 can move freely over the rod 102. The ring 105 can be inserted into the hole 103a of the bracket 103 facing the spring 106. In particular, the spring 106 remains pressed between the bottom of the bracket 103 and the flange 105a of the ring 105. The ring will be in the hole 103a and pushed towards the rod 102 by a spring 106.

The ring 105 / end of the part is fastened to the ring end of the chain 107 suitable for connecting an anti-skid system (not shown), such as the method disclosed in PCT / IB03 / 02898.

On the other hand, the last ring opposite the chain 107 is fixed to the flexible component 108 so that it can be fixed to a part of the anti-skid system to prevent it from shaking while the vehicle is in motion. The flexible component 108 may generally be made of elastomeric material, ie, rubber.

The connecting device also has an operating handle 110 to easily operate the coupling body 100 together with the connecting rod 101.

According to the first embodiment of the present invention, the handle 110 is usually made of plastic and rotates and moves mutually with the operation bush 111. The bush has a threaded hole 111a in which the threaded end portion 101b of the connecting rod 101 enters.

This connecting rod is provided with an operating handle 101a, and the surface may be additionally roughened, the utility of which is described further later.

The spacer 112 has a hole passing in the axial direction. Disposed between the coupling body 100 and the stationary component 113, the stationary component performing the fundamental function of installing the outer ring on the hub, except for the function within the anti-skid system, rather than being part of the connecting device, Parts belonging to the vehicle.

According to the present invention, at least one of the fixing bolts of the wheels itself must be replaced with the corresponding parts that are modified.

In the embodiment shown in Figure 2 the device of the present invention is designed to be connected to a fixed part in the form of a nut 113 extending in the axial direction.

Characteristically, the nut 113 is suitable for use for fixing the outer ring to a vehicle hub employing a protruding bolt, for example used in Korea.

The extension nut 113 modified according to the needs of the present invention is shown well in Fig. 4A. It has the shape of a hexagonal column (diameter 17 mm, 19 mm or 21 mm, if necessary) and has a generally threaded hole 113a therein so that it can fit over the bolt of the wheel hub.

According to the present invention, the extension nut 113a is supplemented to have an auxiliary hole 113b threaded in the axial direction. For example, drill the head of a nut threaded to M8, the opposite end that is not used to secure the outer ring of the wheel.

According to the purpose of the present invention, only one of the wheel nuts needs to be supplemented according to this method. Other nuts may be left in their standard form (ie, without holes 113b).

The threaded end portion of the connecting rod 101 enters the threaded auxiliary hole 113b and is engaged with each other.

In this way, the connecting rod 101 can be fixed to the fixing component 113 in a suitable and secure manner so as not to be accidentally separated.

In particular, the connecting rod 101 passes through the inside of the bush 111, the coupling body 100, the spacer 112 and is screwed into the last extended nut 113. This, in itself, allows the entire connecting device to be securely coupled to the wheel outer ring via the fixing part 113.

On the other hand, in order to properly tighten the device to the nut 113, the handle 110 is operated to turn the threaded end portion 101b of the connecting rod 101 so that the coupling body 100 and the spacer 112 are connected to the nut 113. ) So that it is locked tightly. In this way, the entire connecting device is securely fixed.

The advantage of making this adjustment is obvious-as in the devices of the known art-it is possible to reliably fix the connecting device via the handle 100, i.e. via a readily available operating device. The handle does not loosen even when it is hard to be filled and does not loosen, and the connecting rod 101 is always fixed to the component 113 because the connection of the screw 113 to the hole 113a.

In addition, while operating the handle 110 to secure the various components, the rod 102 also has the important effect of being able to accurately fix it in a specific position (otherwise it will move freely around the axis of the connecting rod 101). This allows the user to first fasten the connecting rods 101, orient the rods 102 in the desired direction (i.e. according to the radiographic image towards the center of the vehicle wheel) and then turn the handle to secure the rods there. This makes it easy to connect the device to the stationary part.

In the embodiment shown in Fig. 3, the device of the present invention is designed for fastening to a fixed part in the form of a general bolt (e.g. 17, 19 or 21 mm in diameter having standard dimensions) with a hexagonal head 114. .

In Europe, for example, hexagonal head bolts are used to secure the wheel's outer ring to a hub with threaded holes.

In order to utilize the connection device of the present invention, at least one bolt of each wheel must be modified as shown in FIG. 4B. In the figure, like the auxiliary hole 113b of the elongated nut 113, the hexagon head 114 of the bolt also has a hole 114b (for example, female thread M8 dimension).

The use of the threaded hole 114b is absolutely the same as that of the auxiliary hole 113b. That is, it is for reliably engaging with the threaded end portion of the connecting rod (101).

Since all the parts described in connection with FIG. 2 are shown in the same embodiment in FIG. 3, the description is not repeated. However, in the embodiment of Figure 3 there are additional components that engage with the head 114 of the bolt. This coupling device is disposed between the spacer 112 and the head 114 of the bolt and includes a bush body 201. It is equipped with a deformable clamping device and a socket 202. The adjustment of this part is consistent with what has been described in relation to the bush body 1 and the socket 2 of FIG.

In this case, the device allows the user to prepare all other parts, and then initially turn the handle 101a simply to turn the threaded rod portion 101b of the connecting rod 101 into the safety hole 114b.

Once the device is securely inserted, the handle 110 can be rotated to be firmly locked. Turn handle 110 appropriately close to bolt 114. This forces the socket 202 to be pushed strongly over the bush body 201 so that the relative movement between the bush 201 and the socket 202 yields the desired result and is clamped over the head 114 of the bolt. .

The two embodiments of FIGS. 5 and 6 clearly show the fully assembled state before the device is fastened to the stationary part, respectively.

Different combinations of the components of Figures 2 and 3 can be made to produce additional finished shapes. For example, an extended nut 113 with an auxiliary hole or a drilled bolt 114 may be combined with a device with or without clamping devices 202 and 201.

Although the second embodiment is shown with a bolt body 114 with a bush body and a socket, it is also possible to apply a nut 113 extending in the longitudinal direction instead of the bolt 114.

As can be understood from the above description, the connecting device of the present invention is very simple and intuitive even for users familiar with the known technology system.

The necessary operation is to first turn the handle 101a, then turn the handle 110, all can be performed the same without difficulty.

The beneficial results introduced by the present invention are derived from the simultaneous adoption of a threaded connecting rod and a handle, which pass through the device vertically and reliably engage with the stationary component.

By essentially adopting a connecting rod with handle 101a and a handle 110 at the same time, on the one hand it secures the connecting device in the threaded hole of the bolt 114 or the nut 111 so that unwanted separation from the wheel does not occur. – The bar device of the anti-slip system works reliably and effectively, since it can be securely engaged and on the other hand the handle can be securely and firmly fixed.

Therefore, the purpose mentioned at the outset was met perfectly.

The present invention is not limited to the above-described specific setting manners, which are only some examples, and do not limit the value of the invention, and the technology corresponding to the tributaries of the invention without departing from the scope of the invention described in the appended claims. Many variations are possible within the value of.

For example, in the above description, the spacer 112 is treated as a separate component, but if the coupling body 100 is made long enough to replace even the spacer, the spacer may not be necessary. The necessity of having a sufficiently long spacer (or coupling body) arises because the outer ring is very wide and the holes for fitting the fastening parts are very deep. In this case, the coupling body or the spacer had to be at least as long as the hole depth of the outer ring so that the connecting rod could come into contact with the outer ring but not collide with the outer ring.

In addition, even if the surface encountered between the spacer 112 and the nut 113 is basically a flat surface (vertical direction of the connecting rod 101 axis), the end of the spacer 112 or the end of the coupling body 100 ( If the spacer is not in the form of a hexagon socket (same shape as a socket spanner), it may be able to engage or fit into the distal end of the nut 113.

In addition, in place of, or in addition to, the handle 101a at the outer end of the threaded connecting rod, it may be provided with a hole for a hexagonal head or allen key (to the same dimensions as the fixed part). will be. This modification allows the user to more effectively rotate the connecting rods onto the stationary parts and secure the device by using a suitable tool (socket spanner or allen wrench).
