Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention mainly relates to a wheel step that is attached to a wheel of a cab-over type vehicle.

[Conventional technology]

Conventionally, as shown in FIG.
In practical use, the outer peripheral surface of the wheel step 6 is used as a tread surface. However, this has a problem in that when the front wheels 4 have a large diameter, the ground clearance of the tread is high, making it difficult to get on and off the vehicle.

In the vehicle wheel step disclosed in Japanese Utility Model Application Publication No. 56-83545, a cylindrical body is formed by winding a band plate with a U-shaped cross section and a tread surface, and a plurality of mounting plates are connected to one side edge of the cylindrical body. are overlapping and fixed to the disc wheel with bolts and nuts.

The wheel step described above makes efficient use of materials in that it is possible to manufacture cylindrical bodies with different outer diameters to correspond to the wheels, but the finished product cannot accommodate the number of bolts that secure the wheel disc to the axle. There is no commonality.

[Problem that the invention attempts to solve]

In view of the above-mentioned problems, the purpose of the present invention is to
It is an object of the present invention to provide a wheel step for a vehicle that can be commonly attached to various wheels.

[Means to solve the problem]

In order to achieve the above object, the configuration of the present invention concentrically connects a notched inner cylinder fitted onto a hub case and a notched outer cylinder having a tread surface by a plurality of stays extending in the radial direction, A tightening bolt is screwed into a pair of stays in the notch.

[Effect]

According to the present invention, by inserting the inner cylinder into the hub case and tightening the tightening bolt, the inner cylinder is tightly wound and fixed to the hub case. Regardless of the number of bolts used to fix the hub case to the axle, the hub case can be fixed even if the outer diameter of the hub case differs to some extent, and can be commonly used for various wheels.

The driver puts his hand on the door, puts his foot on the tread on the inner circumference of the outer tube, then puts his foot on the tread on the outer circumference of the outer tube, and the step height is low, making it easy to reach the driver's cabin. You can board.

[Example of idea]

As shown in Figures 2 and 3, the wheel disc 9
In a front wheel mechanism including a hub case (a case of a wheel reduction gear device) 5 and a front wheel 4, a wheel step 10 is constructed by connecting stays 26 having a U-shaped cross section back to back between an outer cylinder 20 and an inner cylinder 21. be done. The end edge of the outer cylinder 20 is folded radially inward to have a U-shaped cross section. The inner peripheral surface of the outer cylinder 20 is the tread surface 13
The outer peripheral surface of the outer cylinder 20 forms the tread surface 12. Both the outer cylinder 20 and the inner cylinder 21 have one notch, and a stay 26 is disposed at the end of the notch.

As shown in Fig. 4, a pair of stays 2 in the notch
A nut 28 having mutually opposite threaded holes is coupled to 6, and a tightening bolt 27 having mutually opposite threaded grooves at both ends is screwed into the nut 28. A hexagonal tool engaging portion is integrally formed in the middle portion of the tightening bolt 27 .

The inner cylinder 21 is fixed to the hub case 5 by inserting the wheel step 10 having such a structure into the hub case 5 and tightening the tightening bolts 27. Preferably, in order to prevent the wheel step 10 from coming off, lock plates 24 having an L-shaped cross section are attached at several locations using bolts 25 for fixing the hub case 5 to the axle.

Note that the outer cylinder 20 is provided with small holes or embossments to prevent slipping and mud clogging.

By configuring the present invention as described above, when riding, the tread surface 13 on the inner peripheral surface or the stay 26
By putting your feet on the tread surface 12 on the outer peripheral surface, you can easily ride even if the front wheels 4 have a large diameter.

[Effect of idea]

As described above, the present invention concentrically connects a notched inner cylinder fitted onto a hub case and a notched outer cylinder having a tread surface by a plurality of stays extending in the radial direction, and one pair of the notched parts Because the bolts are screwed onto the stay, you can easily get into the driver's cab by first stepping on the treads on the inner circumference and then on the treads on the outer circumference. Since the first step is low, getting on and off is greatly improved.

According to the present invention, by inserting the inner cylinder into the hub case and tightening the tightening bolts, the inner cylinder is tightly wound and fixed around the hub case, regardless of the number of bolts used to secure the wheel disc to the axle. Moreover, even if the outer diameter of the hub case differs to some extent, it can be fixed and can be commonly used for various wheels.
