Description

本発明は、走行時や停止時に車体の姿勢が安定し、旋回時のコーナリング性能も良好な鞍乗型の三輪車に関する。   The present invention relates to a straddle-type tricycle in which the posture of a vehicle body is stable when traveling or stopped and the cornering performance during turning is good.

従来、鞍乗型の三輪車にあっては、例えば酒店やピザ店等の配達に使用されているスクーターの後輪を二輪にしたような三輪車がよく知られているが、コーナリング時にはライダーが身体を傾ける等の必要があるため、コーナリング性能を向上させるため、左右の後輪を揺動可能に支持するサスペンションアームと、このサスペンションアームを車体に懸架するアクティブサスペンションを備えた鞍乗型三輪車において、操舵角を検出するセンサと車速を検出するセンサを設け、操舵角と車両速度によってアクティブサスペンションの伸張量を制御するような技術が知られている（例えば、特許文献１参照。）。すなわち、この技術では、車速と操舵角に基づき、ハンドルの操作側（カーブの内側）のアクティブサスペンションを収縮させると同時に、反対側（カーブの外側）のアクティブサスペンションを伸張させ、舵角が大きいほど、また車速が大きいほど伸縮量を大きく制御するようにしている。
特開２００６−３２７２４４号公報 Conventionally, in a saddle riding type tricycle, a tricycle in which a rear wheel of a scooter used for delivery in a liquor store or a pizza store is used as a two-wheeler is well known. In order to improve cornering performance, it is necessary to incline, etc. A technique is known in which a sensor for detecting an angle and a sensor for detecting a vehicle speed are provided, and the extension amount of the active suspension is controlled by the steering angle and the vehicle speed (see, for example, Patent Document 1). That is, in this technique, the active suspension on the steering side (inside the curve) is contracted based on the vehicle speed and the steering angle, and at the same time, the active suspension on the opposite side (outside the curve) is extended, and the steering angle increases. Also, the greater the vehicle speed, the greater the amount of expansion / contraction.
JP 2006-327244 A

一方、前輪が二輪で、後輪が一輪の跨座式小型三輪車も知られており（例えば、特許文献２参照。）、この技術では、アウトドアにおける目的地等で資材等を運搬するのに適した分割構造の小型車両を提供するため、車体フレームとパワーユニットを別体に構成して両者を分解、結合自在にするとともに、車体フレーム側に前輪操舵装置と前輪ブレーキ走査装置を設置し、パワーユニット側に、エンジン出力を制御するアクセル操作装置と後輪ブレーキ装置と燃料タンクを設置するようにしている。
特開２００４−３０６７３９号公報 On the other hand, a straddle-type small tricycle with two front wheels and one rear wheel is also known (see, for example, Patent Document 2). This technology is suitable for transporting materials and the like at outdoor destinations. In order to provide a compact vehicle with a split structure, the body frame and the power unit are configured separately so that they can be disassembled and combined, and a front wheel steering device and a front wheel brake scanning device are installed on the body frame side. In addition, an accelerator operating device for controlling engine output, a rear wheel brake device, and a fuel tank are installed.
JP 2004-306739 A

ところで、前記特許文献１のように、操舵角を検出する操舵角センサや、車速を検出する速度センサを設けてアクティブサスペンションを伸縮させてコーナリング性能の向上を図るような技術は、装置構成が複雑化するとともに、制作費が高価になるという問題がある。また、特許文献２のように、車体フレームとパワーユニットを分割構成し、パワーユニット側にアクセル操作装置や燃料タンクなどを設けるような技術は、パワーユニットを後方に配置した場合に、重心が一輪である後輪側に集中するため、車体の姿勢が停止時を含んで不安定になりがちで、しかも重心が操向輪である前輪から遠ざかるため、旋回時のコーナリングも安定しないという問題がある。   By the way, as in Patent Document 1, a technique for providing a steering angle sensor for detecting a steering angle and a speed sensor for detecting a vehicle speed to extend and contract an active suspension to improve cornering performance has a complicated apparatus configuration. There is a problem that the production cost becomes high. In addition, as in Patent Document 2, a technique in which a vehicle body frame and a power unit are divided and an accelerator operating device, a fuel tank, and the like are provided on the power unit side, Since it concentrates on the wheel side, the posture of the vehicle body tends to become unstable including when stopped, and the center of gravity moves away from the front wheel, which is a steered wheel, so that cornering during turning is not stable.

そこで本発明は、鞍乗型三輪車において、高速や低速の走行時のみならず停止時を含んで車体が安定し、旋回時にもコーナリングが安定するようにすることを目的とする。   SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to make a vehicle body stable in a straddle-type tricycle, including not only when traveling at high speeds and low speeds but also when it is stopped, and cornering is stable even when turning.

上記目的を達成するため本発明は、前輪が二輪で後輪が一輪で、エンジンの駆動力がチェーンを介して後輪に伝達される鞍乗型三輪車において、前記エンジンと後輪との間に中間軸を設け、この中間軸に設けたスプロケットに第１のチェーンを介して駆動力を伝達するとともに、このスプロケットに伝達された駆動力を第２のチェーンを介して後輪に伝達するようにし、また、前記中間軸に後輪を揺動自在に支持するためのスイングアームを枢着するようにした。   In order to achieve the above object, the present invention provides a straddle-type tricycle in which the front wheel is two wheels and the rear wheel is one wheel, and the driving force of the engine is transmitted to the rear wheels via a chain, between the engine and the rear wheels. An intermediate shaft is provided, and the driving force is transmitted to the sprocket provided on the intermediate shaft via the first chain, and the driving force transmitted to the sprocket is transmitted to the rear wheel via the second chain. In addition, a swing arm for pivotally supporting the rear wheel on the intermediate shaft is pivotally attached.

このように、エンジンと後輪との間に二本のチェーンを設けることにより、重量物であるエンジンをより前方の二輪側に配置することが可能となり、停止時等を含んで車体の安定が図られると同時に、重心が操向輪である前輪に近づくようになるため、旋回時のコーナリング性能が安定する。
また、駆動力はエンジンから中間軸のスプロケットを介して後輪に伝達されるため、中間軸より下流側に着目した場合、中間軸のスプロケットが出力部としての役割を果たすと同時に、後輪が出力部からの駆動力を入力する入力部として作用するようになり、出力部となる中間軸に直接スイングアームを枢着することにより、後輪が揺動した場合でも、出力部と入力部の間に配設される第２のチェーンの長さが一切変化せず、駆動力伝達を安定させることができる。
これに対して、エンジンから後輪まで一本のチェーンにより駆動力を伝達しようとすると、エンジンを前方に配置した場合に、チェーンの長さが長くなってたるみ等が発生しやすくなり、逆に、エンジンを後方に配置すると、重心が一輪側に移動して車体の安定度が損なわれると同時に、重心が操向輪である前輪から遠ざかり、コーナリング性能も悪化する。
因みに、後輪が一輪であると、例えば車椅子を使用する身体障害者等が、後輪の側方に車椅子を横付けして乗り降りし易くなる。 In this way, by providing two chains between the engine and the rear wheel, it becomes possible to place the heavy engine on the front two wheels side, and the stability of the vehicle body, including when stopped, etc. At the same time, the center of gravity approaches the front wheel, which is a steered wheel, so that cornering performance during turning is stabilized.
In addition, since the driving force is transmitted from the engine to the rear wheel via the intermediate shaft sprocket, when focusing on the downstream side of the intermediate shaft, the intermediate shaft sprocket serves as an output section, while the rear wheel It acts as an input unit that inputs the driving force from the output unit, and even if the rear wheel swings by pivoting the swing arm directly on the intermediate shaft that is the output unit, the output unit and the input unit The length of the second chain disposed between them does not change at all, and the driving force transmission can be stabilized.
On the other hand, when trying to transmit the driving force from the engine to the rear wheel with a single chain, when the engine is arranged in the front, the chain becomes longer and slack is likely to occur. If the engine is arranged rearward, the center of gravity moves toward one wheel and the stability of the vehicle body is impaired. At the same time, the center of gravity moves away from the front wheel which is the steering wheel, and the cornering performance is also deteriorated.
Incidentally, if the number of the rear wheel is one, for example, a disabled person who uses a wheelchair, for example, can easily get on and off the side of the rear wheel with the wheelchair.

また、本発明では、前記中間軸とスイングアームとを、外付けのピロー型軸受けユニットを介して枢着するようにした。
このように、外付けのピロー型軸受けユニットで中間軸とスイングアームを枢着すれば、枢着部の点検や保守整備等を楽に行うことができる。 In the present invention, the intermediate shaft and the swing arm are pivotally attached via an external pillow type bearing unit.
In this way, if the intermediate shaft and the swing arm are pivotally attached using an external pillow-type bearing unit, the pivoted portion can be easily inspected and maintained.

また、本発明では、前記鞍乗型三輪車としては、チェーンドライブ式の既存の鞍乗型四輪車を改造するようにし、前記中間軸として、鞍乗型四輪車の後輪の車軸を利用するようにした。
すなわち、既存の鞍乗型四輪車としては、例えば外国において販売されているバギー車等を輸入して改造するようにすれば、三輪車に改造することによって日本では側車付き二輪車として簡単に登録することができ、また、改造前の後輪の車軸を中間軸として利用すれば、必要な強度が確保されると同時に、大幅なコストダウンや製造工程の短縮が図られ、都合が良い。 In the present invention, as the straddle-type tricycle, a chain drive type existing straddle-type four-wheel vehicle is modified, and the axle of the rear wheel of the straddle-type four-wheel vehicle is used as the intermediate shaft. I tried to do it.
In other words, as an existing saddle-ride type four-wheeled vehicle, for example, by importing a buggy vehicle sold in a foreign country and remodeling it, it is easily registered as a two-wheeled vehicle with a side vehicle in Japan by modifying it to a tricycle If the rear axle of the rear wheel before modification is used as an intermediate shaft, the required strength can be ensured and the cost can be greatly reduced and the manufacturing process can be shortened.

エンジンと後輪との間に中間軸を設け、二本のチェーンで後輪に駆動力を伝達するようにするとともに、中間軸に直接スイングアームを枢着することにより、車体の安定やコーナリング性能の向上が図れると同時に、後輪が揺動してもチェーンが弛んだり、無理な引っ張り力がかかることなく、駆動力伝達を安定させることができる。そして、中間軸とスイングアームとの枢着部に外付けのピロー型軸受けユニットを使用することで、点検や保守整備等を楽に行うことができ、また、既存の鞍乗型四輪車を改造すれば、大幅なコストダウンが可能で製造時間の短縮も図られる。   An intermediate shaft is provided between the engine and the rear wheel so that the driving force can be transmitted to the rear wheel with two chains, and a swing arm is directly attached to the intermediate shaft, thereby stabilizing the vehicle body and cornering performance. At the same time, the transmission of the driving force can be stabilized without causing the chain to loosen or excessive pulling force even when the rear wheel swings. In addition, by using an external pillow-type bearing unit at the pivot joint between the intermediate shaft and swing arm, inspection and maintenance can be performed easily, and existing saddle-type four-wheel vehicles can be modified. If so, the cost can be significantly reduced and the manufacturing time can be shortened.

本発明の実施に形態について添付した図面に基づき説明する。
ここで図１は本発明に係る鞍乗型三輪車の一例を示す外観図、図２は車体フレームの概要を示す平面図、図３は同側面図、図４は中間軸部分の説明図、図５はピロー型軸受けユニットの一例を示す説明図、図６はスイングアームが揺動したときの作用を説明する説明図である。 Embodiments of the present invention will be described with reference to the accompanying drawings.
1 is an external view showing an example of a saddle riding type tricycle according to the present invention, FIG. 2 is a plan view showing an outline of a body frame, FIG. 3 is a side view thereof, and FIG. 4 is an explanatory view of an intermediate shaft portion. 5 is an explanatory view showing an example of a pillow-type bearing unit, and FIG. 6 is an explanatory view for explaining the operation when the swing arm swings.

本発明に係る鞍乗型三輪車は、例えば５０〜４００ｃｃ程度のオートバイのエンジン等を利用した鞍乗型の三輪車において、高速や低速の走行時のみならず停止時を含んで車体が安定し、旋回時にもコーナリング性能が向上するように配慮されており、既存の鞍乗型四輪車を改造すれば極めて安価にかつ容易に製造することができる。   The straddle-type tricycle according to the present invention is a straddle-type tricycle using, for example, a motorcycle engine of about 50 to 400 cc. At times, the cornering performance is considered to be improved, and if an existing saddle riding type four-wheel vehicle is modified, it can be manufactured very inexpensively and easily.

そこで、例えば台湾のハー・チー・インダストリアルによって設立されたブランド名「アドリー」の四輪バギーを改造した本実施例について説明する。
本鞍乗型三輪車１は、図１に示すように、二輪の前輪２と一輪の後輪３を備え、シート部４の前方にバーハンドル５を備えた三輪車であり、図２、図３に示すように、車体フレーム６の前部側にエンジン７が配設されるとともに、エンジン７と後輪３との間には、中間軸８が設けられている。 Thus, for example, a description will be given of a modified example of a four-wheel buggy with a brand name “ADRY” established by Her Qi Industrial in Taiwan.
As shown in FIG. 1, the saddle riding type tricycle 1 is a tricycle having two front wheels 2 and one rear wheel 3 and a bar handle 5 in front of a seat portion 4. As shown, an engine 7 is disposed on the front side of the body frame 6, and an intermediate shaft 8 is provided between the engine 7 and the rear wheel 3.

そして、この中間軸８は、改造前の鞍乗型四輪車の後輪の車軸を利用するようにされており、具体的には、改造前の鞍乗型四輪車でスイングアームとして使用されていた改造前スイングアーム部材１１を複数の連結フレーム１０によって車体フレーム６に連結することで固定した状態にするとともに、改造前の後輪の車軸を所定の長さだけ短く切断し、これを改造前スイングアーム部材１１の車軸取付部に固定している。   This intermediate shaft 8 uses the axle of the rear wheel of the saddle-ride type four-wheel vehicle before remodeling. Specifically, the intermediate shaft 8 is used as a swing arm in the straddle-type four-wheel vehicle before remodeling. The pre-remodeling swing arm member 11 is fixed by being connected to the vehicle body frame 6 by a plurality of connecting frames 10, and the rear wheel axle before remodeling is cut short by a predetermined length. It is fixed to the axle mounting portion of the swing arm member 11 before modification.

そして、この中間軸８の中間部の所定箇所には、図４に示すような回転自在なスプロケット部材１２を嵌合させており、このスプロケット部材１２には、第１歯車１２ａと第２歯車１２ｂを設けている。   A rotatable sprocket member 12 as shown in FIG. 4 is fitted to a predetermined portion of the intermediate portion of the intermediate shaft 8, and the first gear 12a and the second gear 12b are fitted to the sprocket member 12. Is provided.

そして、前記エンジン７の駆動力が伝達される変速機１３（図２、図３）の出力軸のスプロケット（不図示）と中間軸８側のスプロケット部材１２の第１歯車１２ａとの間には、第１のチェーン１４が設けられており、中間軸８のスプロケット部材１２の第２歯車１２ｂと後輪３の車軸９のスプロケット（不図示）との間には、第２のチェーン１５が設けられている。   Between the sprocket (not shown) of the output shaft of the transmission 13 (FIGS. 2 and 3) to which the driving force of the engine 7 is transmitted and the first gear 12a of the sprocket member 12 on the intermediate shaft 8 side. The first chain 14 is provided, and the second chain 15 is provided between the second gear 12b of the sprocket member 12 of the intermediate shaft 8 and the sprocket (not shown) of the axle 9 of the rear wheel 3. It has been.

このため、エンジン７からの駆動力は、変速機１３や第１のチェーン１４を介してスプロケット部材１２に伝達され、このスプロケット部材１２に伝達された駆動力は、第２のチェーン１５を介して後輪３に伝達される。   For this reason, the driving force from the engine 7 is transmitted to the sprocket member 12 via the transmission 13 and the first chain 14, and the driving force transmitted to the sprocket member 12 is transmitted via the second chain 15. It is transmitted to the rear wheel 3.

また、中間軸８の両側端部には、左右一対のスイングアーム１６の前端部側がピボット点として揺動自在に枢着されており、スイングアーム１６の後端部側は、後輪３の車軸９に枢着されている。   Further, the front end portions of the pair of left and right swing arms 16 are pivotally attached to both end portions of the intermediate shaft 8 as pivot points, and the rear end portion side of the swing arm 16 is the axle of the rear wheel 3. 9 is pivotally attached.

そして、それぞれのスイングアーム１６の中間上部と車体フレーム６との間には、スイングアーム１６を懸架するサスペンションスプリング１７が設けられている。
因みに、本スイングアーム１６は、図４に示すように、２枚のプレート板を複数のアルミ製のスペーサ部材３０を介して連結ボルト等で連結することで軽量化を図っており、容易に分解できるようにしている。 A suspension spring 17 for suspending the swing arm 16 is provided between the middle upper part of each swing arm 16 and the vehicle body frame 6.
Incidentally, as shown in FIG. 4, the swing arm 16 is reduced in weight by connecting two plate plates with connecting bolts or the like via a plurality of aluminum spacer members 30, and can be easily disassembled. I can do it.

ところで、中間軸８とスイングアーム１６の枢着部には、外付けのピロー型軸受けユニット１８が使用されている。
このピロー型軸受けユニット１８は、スイングアーム１６の外側にボルト止め等により固定されており、その構造の一例としては、図５に示すように、内輪２０と外輪２１が両者間に配設される複数の軸受ボールにより回転自在にされるような構造のものである。なお、本実施例では、ピロー型軸受けユニット１８の取り付け箇所にスペーサ部材３０としてアルミブロックを介装しており、剛性の確保を図っている。 By the way, an external pillow-type bearing unit 18 is used at the pivot portion of the intermediate shaft 8 and the swing arm 16.
The pillow-type bearing unit 18 is fixed to the outside of the swing arm 16 by bolting or the like. As an example of the structure, as shown in FIG. 5, an inner ring 20 and an outer ring 21 are disposed between the two. The structure is such that it can be rotated by a plurality of bearing balls. In this embodiment, an aluminum block is interposed as the spacer member 30 at the attachment position of the pillow type bearing unit 18 to ensure rigidity.

このような外付けのピロー型軸受けユニット１８を使用することにより、軸受をスイングアーム１６の内部に設けることに比べて点検や保守整備が容易となる。   By using such an external pillow-type bearing unit 18, inspection and maintenance can be facilitated as compared with the case where the bearing is provided inside the swing arm 16.

以上のような鞍乗型三輪車１の作用等について説明する。
本鞍乗型三輪車１はエンジン７から後輪３に駆動力を伝達するチェーンが二本であるため、重量物であるエンジン７を後輪３から遠く離れた位置に配設することが可能となり、その結果、重心を二輪である前輪２側に近づけて車体を安定させることが容易となる。また、重心を操向輪である前輪に近づけることで、ステアリング性能を向上させ、安定させることができる。 The operation of the saddle riding type tricycle 1 as described above will be described.
Since the saddle riding type tricycle 1 has two chains for transmitting the driving force from the engine 7 to the rear wheel 3, the heavy engine 7 can be disposed far away from the rear wheel 3. As a result, it becomes easy to stabilize the vehicle body by bringing the center of gravity closer to the front wheel 2 side which is the two wheels. In addition, the steering performance can be improved and stabilized by bringing the center of gravity closer to the front wheels, which are steered wheels.

また、不整地等を走行中に、例えば図６に示すように、後輪３が跳ね上がるように揺動した場合でも、第２のチェーン１５はスイングアーム１６の揺動軸である中間軸８と後輪３との間に設けられているため、後輪３が揺動しても第２のチェーン１５の長さは一切変化せず、弛んだり、無理な引っ張り力が加わるような不具合がない。   Further, even when the rear wheel 3 swings so as to jump up while traveling on rough terrain, for example, as shown in FIG. 6, the second chain 15 and the intermediate shaft 8 that is the swing axis of the swing arm 16 Since it is provided between the rear wheel 3 and the rear wheel 3 swings, the length of the second chain 15 does not change at all, and there is no problem that the second chain 15 is loosened or an excessive pulling force is applied. .

このため、高速でも低速でも停止時でも車体が安定するとともに、旋回時のコーナリング特性も良好であり、しかも、チェーンの耐久性向上を図ることができる。
しかも、本実施例では、外国において販売されている四輪バギー車を改造しているため、日本では側車付き二輪車として簡単に登録することができ、また、改造前の後輪の車軸を中間軸として利用しているため、必要な強度が確保されると同時に、大幅なコストダウンや製造工程の短縮が図られる。また、燃費もよい。
また、中間軸８とスイングアーム１６の枢着部に、外付けのピロー型軸受けユニット１８を使用しているため、点検や保守整備を楽に行うことができる。
また、後輪３が一輪であるため、車椅子を使用する身体障害者等にとって特に乗り降りが便利であり、この場合は、後輪３の横に車椅子を横付けし、片手でシート部４を、もう一方の片手でハンドル５を握って勢い良く立ち上がることにより簡単に乗り移ることができる。 For this reason, the vehicle body is stable at high speed, low speed and when stopped, cornering characteristics at the time of turning are good, and the durability of the chain can be improved.
In addition, in this embodiment, a four-wheel buggy car sold in a foreign country is modified, so it can be easily registered as a two-wheeled vehicle with a side car in Japan, and the axle of the rear wheel before the modification is intermediate. Since it is used as a shaft, the required strength can be secured, and at the same time, the cost can be greatly reduced and the manufacturing process can be shortened. Also, fuel efficiency is good.
In addition, since an external pillow-type bearing unit 18 is used at the pivot part of the intermediate shaft 8 and the swing arm 16, inspection and maintenance can be performed easily.
Further, since the rear wheel 3 is a single wheel, it is particularly convenient for persons with disabilities who use wheelchairs. In this case, the wheelchair is placed next to the rear wheel 3, and the seat portion 4 is already attached with one hand. You can easily get on by holding the handle 5 with one hand and standing up vigorously.

なお、本発明は以上のような実施形態に限定されるものではない。本発明の特許請求の範囲に記載した事項と実質的に同一の構成を有し、同一の作用効果を奏するものは本発明の技術的範囲に属する。
例えば、本鞍乗型三輪車１は、四輪バギー車等を改造するものだけでなく、当初から前輪が二輪で後輪が一輪として設計された三輪車にも適用でき、また、バーハンドル式以外の三輪車にしてもよい。 In addition, this invention is not limited to the above embodiments. What has substantially the same configuration as the matters described in the claims of the present invention and exhibits the same operational effects belongs to the technical scope of the present invention.
For example, the saddle riding type tricycle 1 can be applied not only to a modification of a four-wheel buggy, etc., but also to a tricycle designed from the beginning with two front wheels and one rear wheel. It may be a tricycle.

停止時を含めて走行時の車体の安定性がよく、また、四輪に比べて転がり抵抗が少ないため燃費が良好で、しかもコーナリング性能が良いため、スポーツ用やレジャー用としてのみならず、車椅子を使用する身体障害者等を含んで、市街地走行や通勤等における広い分野での普及が期待される。   The vehicle body is stable when traveling, including when it is stopped, and because it has less rolling resistance than four-wheel vehicles, fuel consumption is good and cornering performance is good. It is expected to spread in a wide range of areas such as urban travel and commuting, including the physically disabled.
