JPS5893655A - Fixation of vehicle wheel and spacer used therefor - Google Patents

Abstract

PURPOSE:To make it possible to fix various type of vehicle wheels having different bolt pitches and to reduce cost by a method wherein the spacer in the form of a disk is fixed to a brake drum with screws and the vehicle wheel is fixed to the spacer by means of tightening members. CONSTITUTION:A predetermined number of fixing bolts 15 are fitted about a wheel shaft 11 so that the bolts project outside the brake drum and the spacer 17 in the form of a disk is fixed to the brake drum 13 by means of the bolts passing through the spacer 17, and nuts 23. Further, a support disk 45 is formed integral with the internal surface of a disk section 41 of the vehicle wheel 35 so that the wheel 35 is supported by the disk 45 when the wheel 35 is fixed to the spacer 17. The support disk 45 is provided with grooves 49 for receiving the nuts 23 and throughholes 51. As a result, the wheel 35 can be fixed to the spacer 17 by screw fitting bolts 53 into holes 29 of the spacer 17 through the throughholes 51.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a vehicle wheel in which a brake drum can be attached to the same vehicle wheel regardless of the bolt pitch, and the distance between the wheels can be freely selected. The attachment relates to the method and the spacer used in the method.

Conventionally, when attaching a vehicle wheel to a brake drum, the required number of bolts were attached to the brake drum, and the vehicle wheel with bolt through holes was brought into contact with the brake drum, and the bolts were inserted through the bolts. The vehicle wheel is screwed into the hole by passing a bolt through the hole and inserting a working glass.

However, in order to install the required number of bolts protruding from the brake drum, the pitch between the bolts differs depending on the vehicle manufacturer, so special wheels for use in the car are required.
Therefore, when replacing a vehicle, a high economic burden is placed on the user. Furthermore, when the user wants to adjust the distance between the wheels, a corresponding vehicle wheel is required, which places a heavy financial burden on the user.

The purpose of the present invention is to solve these inconveniences by reducing the economic burden on the user by allowing the same vehicle wheel to be mounted regardless of bolt pitch and wheel distance. The purpose of attaching a vehicle wheel mount 9 is to provide a spacer used in the method, and its configuration is to screw a spacer made of a disk to the brake drum, and attach the holder for the 7 to the vehicle wheel to this spacer. The special feature is that the bolt can be attached with multiple fasteners.

) This is a Z-spacer characterized by consisting of a disc body provided with a through-hole for a bolt and a means for taking a vehicle wheel.

Embodiments of the present invention will be described below based on the drawings.

．． 15.15. It is perforated to match the pitch of... A taper 25 is formed at the upper end edge of the bolt through hole 21 to make tightening by four nuts 23 described later more rigid. The upper surface of the spacer 17 is provided with an engaging hole 29 having a female thread in the inner circumferential direction for mounting the vehicle wheel 35 thereon. In addition, there are other methods for attaching the spacer 17, such as adhesion and melting. To fix this spacer 17 to the brake drum 13, the axle 11 is passed through the shaft hole 19 of the spacer 17, and an iron pusher is used.

33.33. The bolt through holes 21, 21, of the spacer 17 fitted therein. The installation of the brake drum 13 is done by Paul) 15.15. A mounting hole 15- + that extends through the spacer 17 and abuts the outer surface of the brake drum 13 to protrude from the surface of the spacer 17.

Next, 35 is a vehicle wheel, which is constructed by integrally molding a rim 37 and a disk portion 411 having shaft holes 43 and 39 in the center. A support plate body 45 having a shaft hole 43 in the center is integrally molded on the inner sacral surface of the disk portion 41, and this support plate body 45d supports the wheel 35 when the vehicle boiler 35 is attached to the spacer 17. be. A recess 47 into which the end of the spacer 17 is inserted is formed at the tip of the support plate 45. A recess 47 is formed on the surface of the support plate 45 and is a nut accommodating groove. There is. 511Ii bolt through hole, through which the retaining bolt 53 passes loosely when fixing the vehicle wheel 35 to the spacer 17. Note that an enlarged diameter portion 57 is provided at the outer end of the through hole 51 in which a neck portion 55 of an engagement bolt 53 made of a hexagon socket head bolt is embedded. Note that this groove is provided on the surface of the support plate body 45 to reduce the weight of the wheel 35 for vehicles manufactured by 59 companies.

To attach the vehicle wheel 35 to the spacer 17, insert the axle 11 into the shaft hole 43 of the vehicle wheel, bring the vehicle wheel 35 into contact with the spacer 17, and then The shaft and the axis of the retaining hole 29 of the spacer 17 are aligned, and the engaging bolt 53 is loosely inserted into the bolt through hole 51 from the outside of the vehicle wheel 35 and screwed into the engaging hole 29 of the spacer P-17. This is what the wheel is screwed onto.

The method for installing the vehicle wheel according to the present invention is to screw a spacer made of a disc body onto the brake drum, and then attach the vehicle wheel to this spacer. Vehicle wheels, which are attached using M number of fasteners, are installed using a special method, that is, a spacer is interposed between the brake drum and the vehicle wheel, so if a suitable spacer is prepared, Install the brake drum between the bolts.
The same vehicle wheel can be attached to the brake drum regardless of the width, width, and distance between the wheels.

Therefore, when installing a brake drum, users need to prepare a spacer appropriate for the pitch between the bolts or the distance between the wheels. This will reduce the financial burden on people.

The spacer according to the present invention is a spacer characterized by having a bolt through hole for mounting and a plate body provided with a means for mounting a vehicle wheel. If the holes are drilled to match the pitch between the bolts, it can be fixed to the brake drum very easily. Also, if the thickness of the disk body is adjusted during manufacture, the distance between the wheels can be changed without replacing the vehicle wheels. Therefore, if a corresponding spacer of this kind is used, the same wheel can be mounted on the play 1-drum regardless of the pitch between the bolts and the distance between the wheels, so use 6 corresponds to the conventional one. Instead of preparing a vehicle wheel, it is better to prepare a corresponding spacer, thereby reducing the economic burden on the user. Also, the spacer is a side dish, and the 11 of the spacer! It is easy to manufacture and process, and it is also possible to manufacture spacers using plate materials, simplifying the process and providing inexpensive products.In addition, the spacer has a transmission function that transmits the rotation of the axle to the wheel. The fastener has a fastening function to connect the wheel and the wheel.
