JPH03213485A - Crawler type running vehicle exchangeable with tyre type - Google Patents

Abstract

PURPOSE:To realize rapid movement by providing a running vehicle, used as a tyre type running vehicle on an ordinary running road and switched to and used as a crawler type running vehicle on a running road, e.g. a snow road, a damp ground, demanding a low earthing pressure, and effecting running responding to a road surface. CONSTITUTION:When a six-wheel drive tyre type running vehicle 40 provided at the front and rear parts on both side and intermediate part with three wheel axles 41a-43a, 41b-43b is varied to a crawler type running vehicle, the tyre running vehicle 40 is first hoisted by means of a chain block and tyres are removed. An upper car body in which the wheel axles 41a-43a, and 41b-43b are left mounted is then moved to a position above the crawler running body formed such that a crawler frame 5 is coupled to the upper part of a running frame 1 through coupling frames 6-8. Retainers 46-48 are securely inserted in the respective U-shaped receiving parts of flanges 2-4 mounted on the running body frame 1. A sprocket 5 for driving a crawler is secured to the tyre flanges of the front axles 41a and 41b on both sides.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a crawler type vehicle that can be freely replaced with a tire type vehicle, and in particular is used as a tire type vehicle on a normal road.
In order to be used as a crawler-type vehicle on running routes that require low ground pressure, such as snowmobiles or wetland vehicles, the tire type and interchangeable crawler are extremely easily interchangeable with the axle still attached to the upper body. Regarding type-driving vehicles.

(Prior Art) Conventionally, a large number of types of traveling vehicles have been produced, each with its own function as a tire-type traveling vehicle or a crawler-type traveling vehicle. The car has not yet been produced.

(Problem to be solved by the invention) Conventionally, for example, when going from a plain area with little snow to a mountain forest area with deep snow, a snowmobile is always parked in the mountain forest area with deep snow, When a passenger car travels through the plains and reaches a mountain forest area with deep snow, it is necessary to switch from the passenger car to a snowmobile and go to work in the mountain forest area, which not only requires two passenger cars and a snowmobile, but also a snowmobile. A lot of money was needed to bring in and take out.

(Means for Solving the Problems) In order to solve the above-mentioned conventional technology, the present invention provides independent left and right axles at least at the front or rear end, and brakes each of the left and right wheels operated by the driver. In the traveling vehicle to be operated, all tire rims are removed from the tire flanges fixed to each axle and other axles, and the crawler flanges of a separately prepared crawler traveling body are attached to the bearing holders of all the axles, and the A sprocket is fixed to the tire flange of each left and right axle at the rearmost or rearmost portion, and the crawler of the crawler traveling body is driven by the sprocket. Moreover, the space between the tire flanges of the left and right axles to which the sprockets were fixed and the brackets was supported by bearings held in bearing retainers fixed to the crawler traveling body so that their positions could be adjusted. The bearing held in the bearing retainer is inserted from the tire flange side of each axle after removing the tire flange from each of the left and right axles. Furthermore, the crawler running body has an upper roller, a lower roller,
The left and right assembly frames to which the A-hydra and the crawler flange are mounted are connected by a connecting member at the lower part of the crawler flange. Tire flanges fixed to axles other than the left and right axles to which the sprockets are fixed are configured to be located within the width of the crawler.

(Operation) According to the above configuration, the operation is performed as follows. Remove all tire rims from the tire flanges fixed to each axle and the other axles, attach crawler flanges of a separately prepared crawler traveling body to the bearing holders of all axles, and attach the crawler flanges of the crawler traveling body separately prepared to the bearing holders of all the axles, and remove the tire rims from the tire flanges fixed to each of the axles and other axles, and attach the crawler flanges of the crawler traveling body prepared separately to the bearing holders of all the axles. A sprocket may be fixed to the tire flange of the vehicle, and the crawler of the crawler traveling body may be driven by the sprocket, and the tire type and crawler type can be interchanged very easily with all axles attached to the upper vehicle body. Furthermore, since the tire flanges of the left and right axles to which the sprockets are fixed are supported between the brackets by bearings, the left and right axles, which tend to be long, can be reliably held. The bearings are unnecessary in the case of a tire-driven vehicle because the tire flanges are removed from each of the left and right axles and inserted from the tire flange side of each axle. The left and right running frames of the crawler running body are connected by a connecting member at the lower parts of the left and right crawler flanges to which the upper car body is attached, so that the upper car body with high tonality is connected to the strength member of the crawler running body. It can be used as Further, since the tire flanges fixed to the axles other than the left and right axles to which the sprockets are fixed are configured to be located within the width of the crawler, it is safe even if the tire flanges rotate during running.

When going to work from a plain area with little snow to a mountain forest area with deep snow, park the snowmobile at all times in the mountain forest area with deep snow, drive a passenger car through the plain area with little snow, and go to the mountain forest area with deep snow. This is economical as there is no need to change from a passenger car to a snowmobile and go to the mountain forest area for work.

(2) Moreover, replacing tire type and crawler type vehicles,
Since it is extremely easy to replace the axle with the axle still attached to the upper vehicle body, it can be easily replaced at the work site.

(3) Furthermore, the large amount of expense required to transport a crawler vehicle such as a snowmobile to and from a work site is eliminated.
