Abstract

PURPOSE:To secure a sufficient loading space on rear wheels by arranging a driven mechanism placed on the shaft between right and left rear wheels closer to one wheel in a vehicle such as tricycle. CONSTITUTION:A gear box 14 is arranged close to one end of a rear wheel shaft 13 in a vehicle equipped with a rear cover 9 having right and left rear fenders 8 on the rear of a frame 2 and right and left rear wheels 11 and 12 acting as driving wheel below the rear fenders 8. On the other hand, an engine 6 is placed at the intermediate position along the width of the vehicle behind the front wheel 5. A power shaft 21 is extended toward the side of a transmission case 601 of the engine 6 on the hand having the gear box 14 and the rotation thereof 21 is transmitted to the gear box 14 through bevel gears 22 and 24 and a propelling shaft 23 arranged inclined back outerward. In this manner, a loading case 31 can be set utilizing the roughly full width between the rear wheels 11 and 12.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in motorized vehicles such as tricycles.

One front wheel 51 and two rear wheels 5 as shown in FIG.
2.52, engine 53' ([-rear wheel 52.5
A tricycle 50 provided in front of the vehicle 2 is known. The drive system of such an automatic tricycle 50 includes a gear mechanism 55 including a full differential device on the rear axle 54 between the rear wheels 52 and 52, and an output section 56 of the transmission gear of the engine 53 and the gear mechanism 55 as the propulsion shaft. Connect with 5T and obtain power In the above case, when loading cargo on the rear of the tricycle, loading the cargo on the rear axle 54 will reduce the front wheel load, and it is preferable to load the cargo on the rear axle. It is preferable to load luggage as low as possible because it is not desirable for stability when traveling on an incline if it is loaded in a high position.

By the way, a gear mechanism 55 is provided in the middle part of the rear axle 54, and a propulsion shaft 57 driven by a gear M55 ffi and the rear axle 5 are connected to each other.
It forms a substantially right angle with 4. Since the gear mechanism 55 is located in the middle of the rear axle 54, the storage compartment 58 is placed on the rear axle 54.
If a carrier is provided, the bottom 58a thereof will be shallow in order to avoid interference with the gear mechanism 55, making it difficult to take up space for the cargo.

The present invention has two rear wheels, a drive mechanism is provided on the rear axle, and it is an object of the present invention to solve the above-mentioned problems in securing a cargo loading space on the rear axle.

The object of the present invention is to provide a storage compartment for loading luggage on the rear axle, and to bring the bottom of the storage compartment as close as possible to the rear axle.
To provide a motorized vehicle in which the storage capacity is expanded and the drive mechanism is designed to do the above rationally, effortlessly, and while ensuring reliable operation.

In order to achieve the above object, the present invention disposes an engine in the middle part in the width direction in front of the rear axle, and biases the drive gear mechanism so that it faces the inside of one rear wheel at one end of the rear axle. The gear mechanism and the engine output section are connected by a propulsion shaft extending obliquely rearward and outward from the output section, and storage compartments are arranged on the shaft except for one end of the drive shaft.

Next, preferred embodiments of the present invention f! This will be explained in detail according to the attached drawings.

FIG. 1 is a schematic side view of a tricycle. The tricycle 1 supports a front fork 4 which supports a front wheel 5 in a steerable manner via a helad tube 3 at the front end of a frame 2. The front wheel 5 is supported by a so-called balloon tie. ■Using ultra-low pressure tires called
- Wheel Steering Wheel 1° Frame 2 The engine 6 is mounted on the lower part of the Ai 1 section, the fuel tank 7 is mounted on the upper part, and the left and right steering wheels 8 are mounted on the rear part of the frame 2.
．． 1'N rear cover 9ff: is provided, and a seat 10 is provided at the front of the cover 9 and behind the fuel tank 7. At the rear of the frame and under the rear fenders 8, 8, two rear wheels 11.12 forming drive wheels are provided spaced apart on the left and right sides, and the rear wheels 11.12
The rear wheels 111 and 121 are connected to both ends of the rear axle 13, and the rear wheels 11 and 12 are made of ultra-low pressure tires.

A gear box 14 is provided near one end of the rear axle 13, for example near the left end, and the axle 13 is divided into left and right parts 131, 132L within the box 14, so that one shaft 131 is extremely short (
, the other shaft 132 is so long as to be close to the full width. A bevel gear 15.16 constituting a differential gear mechanism is provided at the opposing ends of the +fl+ 131 and 132, and a support shaft 18 is provided in the differential case 17 surrounding the gear 15.1.
A pinion gear 19f that meshes with the pinion gear 6 is attached, and a driven gear 20 is fixedly installed around the differential case 17. The gear box 14 is biased toward one end of the axle 13, and the gear box 14 faces the inner diameter portion of the rim 112 of the rear wheel 11 at approximately η in the width direction.

On the other hand, the engine 6 is disposed at an intermediate portion in the vehicle width direction, in front of the front wheels 5 and between the rear wheels 11 and 12.

The output shaft 21 faces the side of the transmission booth 601 of the engine 6 on the side where the 14 gear boxes are provided, and a bevel gear 22 is provided on the output shaft 21. The bevel gear 22 is located near the middle in the vehicle width direction, while the gear box 14 is located near the outside, and a propulsion shaft 23 connects them. Promotion +1I
A bevel gear 24 is provided at the front end of the ll+ 23, and the bevel gear 22 of the output shaft 21 is engaged with the bevel gear 24, and the front end of the propulsion shaft 23 discharges to the middle part in the vehicle width direction, and the rear end faces the gear box 14. It is tilted backward and outward and propelled! A bevel gear 25 provided at the rear end of 1+23 is meshed with a gear 20 in a gear box 14. In this way, the propulsion shaft 23 is arranged diagonally so that the front end is on the inside in the Φ width direction and the rear end is on the outside in the vehicle width direction, and the angle between the vehicle 11qI 113 and the propulsion shaft 23 is thicker than 90° (・0
In the figure, 26 is a cover for the propulsion 111111, 27 is a cover for the axle 130, 2-8 is a handle, 29 is a step, and 30 is a front fender.

As described above, the rear axle 13 is provided with the gearbox 14 extremely biased toward one wheel 11, and therefore there is no protrusion over its entire length in the vehicle width direction. Such rear axle 13
A storage compartment 31 is provided on the top, and the storage compartment 31 is formed in the rear part of the rear cover 9 with a box-like gate extending partially downwardly. The bottom wall 31 of the storage compartment 31 is covered with a cap that can be opened and closed freely.
3 has the full width of the road between the rear wheels 11 and 12, and can be provided close to the rear axle 13. Therefore, the storage container 31 can have a sufficiently large width and depth, and can have a large capacity.

Although the embodiments have been described above in detail, the embodiments are not limited to tricycles, and can be implemented on any vehicle with two rear wheels.

As is clear from the above, according to the present invention, the engine is disposed at the center of the front of the vehicle body, and the driven gear mechanism provided on the axle of the two rear wheels is disposed at the end of the axle that is biased toward one wheel. established,
Since the engine and the driven gear mechanism are connected by a propulsion shaft disposed diagonally, there is a full space on the shaft between the left and right rear wheels in the vehicle width direction. You can set the depth and width of the bottom of the
It is possible to secure a sufficiently large storage space and improve the practicality of this type of vehicle.Also, while the engine is located in the center of the vehicle width, the driven mechanism provided on the rear axle is a gear mechanism, Since both are connected by a bevel gear and a JfF advance shaft, the shaft angle can be selected arbitrarily.
By using a shaft drive mechanism, the above can be achieved without changing the number of conventional parts, and it has many advantages such as being structurally advantageous.
