Description
本考案は、前1輪と後左右に2輪を有し乗員の意思に応じて揺動する自動3輪車の左右揺動をロックする機構に関するものである。 The present invention relates to a mechanism that locks the left and right swing of an automatic three-wheeled vehicle that has one front wheel and two rear left and right wheels that swing according to the intention of the occupant.
自動2輪車は4輪自動車に比べて構造が単純で車両寸法が小さいため広く一般の人に利用されているが、積載量の制約や悪天候時の保護が犠牲になっている。2輪車とほぼ同じ寸法の3輪車が製造されているが旋回時に遠心力により車両及び乗員が外側に傾くため極低速で走行せねばならなく、限られた場所や軽度の業務用の使用に限定されている。 Motorcycles are widely used by ordinary people because they have a simpler structure and smaller vehicle dimensions than four-wheeled vehicles, but at the expense of load restrictions and protection in bad weather. A three-wheeled vehicle with almost the same dimensions as a two-wheeled vehicle is manufactured, but the vehicle and the occupant are inclined to the outside due to centrifugal force when turning, so the vehicle must travel at a very low speed. It is limited to.
この解決策として乗員が旋回時に自分で内側に車体を傾け遠心力と自然に釣合うように運転する3輪の車両も製造されている。これは乗員が座る部分と操舵装置に繋がった前輪を保持するフロントフォークが挿入されるヘッドパイプを連結する2輪車と類似した前部フレームと、左右後2輪を駆動する動力装置を載せた後輪スイングアームを連結した物であるが、この後輪スイングアームが中央部で前後で分割され車両進行方向を軸とする回転軸で連結され揺動可能となっている。この構造上低速で走行するまたは停車した時は足で車両が傾くのを支える必要がる。 As a solution to this problem, a three-wheel vehicle is also manufactured in which the occupant tilts the vehicle body inward when turning to drive to naturally balance centrifugal force. It is equipped with a front frame similar to a two-wheeled vehicle that connects a head pipe into which a front fork that holds a front wheel connected to a steering device and a front wheel connected to a steering device is inserted, and a power device that drives two left and right rear wheels The rear wheel swing arm is connected to the rear wheel swing arm, and the rear wheel swing arm is divided into front and rear parts at the center, and is connected by a rotating shaft with the vehicle traveling direction as an axis so as to be swingable. Due to this structure, it is necessary to support the tilting of the vehicle with the feet when the vehicle runs at a low speed or stops.
駐車する時には別の操作レバーにより動かされるピンが揺動装置の穴部に噛み合いロックすると共に車輪にブレーキがかかり車両が動かなくなるよう工夫されている。
しかし、この構造では穴とピンが正確に噛み合う限られた位置でしか嵌合できないし、走行時には作動できないという問題が残る。
When the vehicle is parked, a pin that is moved by another operating lever is engaged with and locked in the hole of the swinging device, and the wheel is braked so that the vehicle cannot move.
However, this structure has a problem that it can be fitted only at a limited position where the hole and the pin accurately mesh with each other, and cannot be operated during traveling.
解決しようとする問題点は、前1輪と後左右2輪を備え車両進行方向左右に自由に揺動できる自動3輪車において低速時に車両が傾き安定して運転できない点である。 The problem to be solved is that in a three-wheeled motor vehicle having one front wheel and two rear left and right wheels and capable of freely swinging left and right in the vehicle traveling direction, the vehicle cannot be stably driven at a low speed.
本考案は、前部フレームと車両進行方向を軸として回転できるように連結された後輪部が楔状部材またはカム状の部材によって押されることにより自動的に車両を垂直に保持し揺動をロックする機構を最も主要な特徴とする。 The present invention automatically holds the vehicle vertically and locks the swing when the rear wheel portion connected to the front frame so as to be able to rotate about the vehicle traveling direction as an axis is pushed by a wedge-shaped member or a cam-shaped member. The main feature is the mechanism.
本考案の構造は前輪を支持しかつ前輪緩衝機能を備え上部に操舵装置を固定するフロントフォークを取り付けるヘッドパイプ部と乗員が座るシートを支えるパイプ部材とをパイプまたは板金の部材で繋ぎ溶接一体構造とした前部フレームと駆動力を伝える左右2対の後輪を取り付けた後輪スイングアームと後輪緩衝装置とを取り付けた揺動支持部材とからなる。この揺動支持部材を前部フレームに揺動回転軸を介して揺動可能に締結し、旋回時に乗員は着座したシートと共に自然に前部フレームを傾けて安定して走行することができる。しかし車両が低速度で走行する場合乗員は前部フレームを垂直に近い状態にするが前輪操舵で安定を確保することが難しくなる。ある速度以下になると作動するアクチュエーターが前部フレームに取り付けられ楔状のガイドピンを揺動支持部材に一体に取り付けられたガイドプレートに押し入れる。車両が傾斜していてもガイドピンの楔がガイドプレートを押して車両を強制的に垂直に保持するようにする。 The structure of the present invention is a welded integrated structure in which a head pipe portion that supports a front wheel and has a front wheel cushioning function and a front fork for fixing a steering device to an upper portion and a pipe member that supports a seat on which an occupant sits are connected by a pipe or sheet metal member. And a swing support member to which a rear wheel swing arm and a rear wheel shock absorber are attached. The swinging support member is fastened to the front frame so as to be swingable via a swinging rotation shaft, and the occupant can travel stably with the seated seat naturally tilted with the seated seat. However, when the vehicle travels at a low speed, the occupant puts the front frame in a nearly vertical state, but it becomes difficult to ensure stability by front wheel steering. An actuator that operates below a certain speed is attached to the front frame, and a wedge-shaped guide pin is pushed into a guide plate that is integrally attached to the swing support member. Even when the vehicle is inclined, the wedge of the guide pin pushes the guide plate to force the vehicle to be held vertically.
前部フレームは通常の自動2輪車に使用されるようにパイプもしくは板金を用いてヘッドパイプと着座部を溶接一体構造とした物に揺動回転軸を後方下部に一体溶接する。後輪スイングアームは電気もしくは内燃機関にて駆動される左右2輪を保持する部分と緩衝装置の取り付け部分と回転自在に取り付けるピボット部分からなる。揺動支持部材は前部フレームの揺動回転軸に回転自在に勘合するベアリングを組み入れた円筒部と後輪スイングアームを取り付けるスイングアームピボット軸が左右に貫通する円筒部と緩衝装置を取り付ける板金部分を一体構造として成り立つ。揺動支持部材は前部フレームの揺動回転軸に遊びが無くかつベアリングの自由な回転を阻害しないように調整して連結される。このため前1輪と後2輪は揺動回転軸を中心として乗員の意思に従い揺動する。揺動支持部材の上部車体中央部にはガイドプレートが一体化溶接されて、前部フレームにはアクチュエーターが取り付けられその先端には楔形のガイドピンが取り付けられている。車両がある速度になるとアクチュエーターがガイドピンをガイドプレートの側面に押し付けて揺動支持部材と前フレームは同一平面状即ち車両は垂直に保持される。 The front frame uses a pipe or a sheet metal to be used in a normal motorcycle, and the swing pipe is integrally welded to the rear lower part of the head pipe and the seating part having a welded integrated structure. The rear wheel swing arm includes a portion for holding two left and right wheels driven by an electric or internal combustion engine, a mounting portion for a shock absorber, and a pivot portion for rotatably mounting. The swing support member is a cylindrical part incorporating a bearing that is rotatably fitted to the swing rotation shaft of the front frame, a cylindrical part through which a swing arm pivot shaft that attaches a rear wheel swing arm passes left and right, and a sheet metal part that attaches a shock absorber As an integral structure. The swing support member is adjusted and connected so that there is no play on the swing rotation shaft of the front frame and the free rotation of the bearing is not hindered. For this reason, the front 1 wheel and the rear 2 wheels swing according to the occupant's intention about the swinging rotation axis. A guide plate is integrally welded to the center of the upper body of the swing support member, an actuator is attached to the front frame, and a wedge-shaped guide pin is attached to the tip of the actuator. When the vehicle reaches a certain speed, the actuator presses the guide pin against the side surface of the guide plate, and the swing support member and the front frame are held in the same plane, that is, the vehicle is held vertically.
図1は本考案の実施方法を示した車両全体側面図である。1.前部フレームの後方下部に4.揺動回転軸が溶接一体化されている。2.後輪スイングアームと3.緩衝装置は5.揺動支持部材に左右軸に対して回転自在に取り付けられる。この揺動支持部材は前部フレームの揺動回転軸に嵌合される。図2は、本考案装置の1実施例の側面図であって、1〜5は、図1と同様である。また、先端に7.楔形ガイドピンを取り付けた6.アクチュエーターは前フレームに固定され、8.ガイドプレートは揺動支持部材に溶接一体化されている。 FIG. 1 is a side view of an entire vehicle showing a method of implementing the present invention. 1. 3. In the lower rear of the front frame The swing rotation shaft is integrated by welding. 2. 2. rear wheel swing arm; The shock absorber is 5. It is attached to the swing support member so as to be rotatable with respect to the left and right axes. The swing support member is fitted to the swing rotation shaft of the front frame. FIG. 2 is a side view of an embodiment of the device of the present invention, and 1 to 5 are the same as those in FIG. In addition, 7. 5. A wedge-shaped guide pin was attached. 7. The actuator is fixed to the front frame. The guide plate is welded and integrated with the swing support member.
図3は本考案装置の揺動回転軸部、ガイドプレート及びガイドピンの断面図であって、ガイドピンが前方に下がっている場合ガイドプレートは自由に左右に揺動することができる。しかし、車速が下がりアクチュエーターによりガイドピンが後方へ押し出されガイドプレートの穴に挿入されるとその楔形の斜面にガイドプレートの穴の左右側面が押され揺動角を限定していく。ガイドピンが完全に後方へ移動するとガイドプレートの穴と楔が一致し、車両は垂直に保持される。 FIG. 3 is a cross-sectional view of the swing rotation shaft portion, guide plate, and guide pin of the device of the present invention. When the guide pin is lowered forward, the guide plate can freely swing left and right. However, when the vehicle speed decreases and the guide pin is pushed backward by the actuator and inserted into the hole of the guide plate, the right and left side surfaces of the hole of the guide plate are pushed to the wedge-shaped slope, and the swing angle is limited. When the guide pin moves completely rearward, the hole of the guide plate and the wedge coincide, and the vehicle is held vertically.
図4は本考案の楔形ガイドピンとガイドプレートの動作を揺動軸上から見た説明図であり、図上が車両の垂直上を示す。図5では車両が傾斜した状態を示している。 FIG. 4 is an explanatory view of the operation of the wedge-shaped guide pin and the guide plate according to the present invention as seen from above the swing shaft, and the upper side of the figure shows the vertical direction of the vehicle. FIG. 5 shows a state where the vehicle is inclined.
楔形ガイドピンはナイロン等の摺動抵抗が少なくかつ磨耗に対して充分な強度を持つ材料で設計され、小さな力で車体を動かすことを可能にしている。ガイドピンが後方へ移動するとガイドプレートの反対側の支持板の穴にガイドピンの先端が噛み合い車両を垂直に保つのに充分な強度を保つよう工夫されている。 The wedge-shaped guide pin is designed with a material such as nylon that has a low sliding resistance and a sufficient strength against wear, and can move the vehicle body with a small force. When the guide pin moves rearward, the tip of the guide pin is engaged with the hole of the support plate on the opposite side of the guide plate so as to maintain sufficient strength to keep the vehicle vertical.
図6は本考案でのカム形ガイドプレートの動作の説明図である。この場合車両を揺動させると、10.カム形ガイドプレートは9.円筒ガイドピンを上下に押し下げるし、アクチュエーターがガイドピンを押し下げるとカムの形状に沿ってガイドプレートを押し車両を垂直にする力が働く。円筒ガイドピンは接触部にはプラスチックを用い、軸にはベアリングを介して極力抵抗を減らし円滑な動きをするよう工夫されている。 FIG. 6 is an explanatory view of the operation of the cam type guide plate in the present invention. In this case, if the vehicle is swung, The cam type guide plate is 9. When the cylindrical guide pin is pushed up and down and the actuator pushes down the guide pin, a force is applied to push the guide plate along the shape of the cam to make the vehicle vertical. The cylindrical guide pin is devised to use plastic for the contact portion and to make the shaft move smoothly by reducing resistance as much as possible through a bearing.
本案件は既存の部品を使用して組み合わせ製造コストを抑えることができる。風雨から保護される個人的移動手段がより安全に使用できる装置を提供するものとして有用である。 This project can reduce the combined manufacturing cost by using existing parts. It is useful to provide a device in which personal transportation means protected from wind and rain can be used more safely.
