Definitions
- the present invention relates to body structure of industrial vehicle such as a fork lift, and more particularly relates to body structure suitable for a rear wheel drive, battery-operated, three-wheeled fork lift.
- Fig. 5 schematically shows a body structure of a conventional rear wheel drive, battery-operated, three-wheeled fork lift.
- the illustrated fork lift has a drive unit 34 of the type vertically placing a drive motor 33 for driving a rear wheel, the drive unit 34 being attached to the rear side of a frame 31 together with a power steering oil motor 35 and controller 36.
- a large quantity of strengthening material such as a thick steel plate 37 or rib is welded with the rear side of the frame 31 to secure a required strength for attaching such mechanical hardwares as the drive unit 34 and controller 36.
- a counterweight 32 is mounted on the rear end portion of the frame 31, the counterweight 32 having a horizontal section in the form of a substantially U-shape so as to surround mechanical hardwares and strengthening material for supporting them.
- Such body structure is disclosed, for example, in Japanese Patent Laid-Open No. 62-36299 and Japanese Patent Laid-Open No. 5-24555.
- one of the characteristics of a three-wheeled, rear wheel drive fork lift is its compactness and capability of making a small turn. In order to fully use this characteristic, it is necessary to reduce the overall length of the vehicle as much as possible. For this reason, a rearward extension from the outer surface of the counterweight must be avoided.
- the counterweight in the conventional three-wheeled, rear wheel drive fork lift has a constraint on its extension with respect to both the inner surface side and the outer surface side thereof. It has thus been very difficult to clear such constraint to obtain a required weight. Further, since a large quantity of strengthening material such as a thick steel plate or rib is welded with the rear portion of the frame, material cost and processing cost are increased to result in a problem of high cost.
- the body structure according to the present invention includes: a unit attaching portion formed on the counterweight mounted at a rear end portion of the frame; and a drive unit fixed to the unit attaching portion.
- a counterweight 1 formed as a cast product includes a rear portion 2 constituting a rear end portion of the vehicle and left and right side portions 3 monolithically extended frontward from the rear portion 2 to constitute the two side portions of the rear end of the vehicle.

- a unit attaching portion 4 for attaching a drive unit 11 is formed on the inner surface side of the rear portion 2.
- the unit attaching portion 4 is formed into the form of a plate extended substantially horizontally in a direction toward the front with having a required thickness substantially at the mid height on the inner surface of the rear portion 2, the front end edge thereof reaching near the end surface of the side portions 3 and a substantially circular attaching hole vertically penetrating through substantially the center portion thereof.
- the drive unit 11 to be attached to the unit attaching portion 4 includes: a gear case 12; a tire 13 rotatably attached to the gear case 12 around the horizontal axial line thereof; a drive motor 14 serving as a driving unit assembled in its vertical position with an upper portion of the gear case 12; an array of gears (not shown) contained in the gear case 12 and transmitting the driving force of the drive motor 14 to the tire 13; and a substantially ring-like turning base 15 for rotatably supporting an upper end portion of the gear case 12 around a vertical axis thereof through a bearing (not shown).
- the members except the drive motor 14 are attached to a lower surface of the unit attaching portion 4 of the counterweight 1.

That is, the drive motor 14 of the drive unit 11 is so constructed that it is detached/attached from the top of the unit attaching portion 4. In this manner, of the drive unit 11, only the turning base 15 is fixed to the counterweight 1 and the remaining members are provided as capable of a horizontal rotation for the purpose of steering.
- the gear case 12 of the drive unit 11 is attached from the lower surface side of the unit attaching portion 4 and the drive motor 14 is attached to the gear case 12 from the upper surface side of the unit attaching portion 4 through the attaching hole 5.
- the portions corresponding to the bolt attaching positions of the inner peripheral edge of the attaching hole 5 are extended inwardly as shown in Fig. 3 to form protuberances 5a.
- protuberances 17a are formed by outwardly extending the portions of the peripheral edge of the attaching flange 17 corresponding to the bolt attaching positions.
- a predetermined gap is required between the end surface of the hole side protuberance 5a and the end surface of the flange side protuberance 17a in order to avoid interference of the protuberances 5a, 17a with each other in the rotating direction of the drive unit 11.
- the end surface of the hole side protuberance 5a is processed after the forming of the counterweight 1 to secure the required gap therefrom to the flange side protuberance 17a.

- the rear portion of the frame is simplified in construction and a reduction in cost is achieved.
- the conventional type where the mechanical hardwares are mounted on the frame side requires a gap to be provided in order to avoid interference with the mechanical hardwares and strengthening members for attaching them.

Abstract
Description
- The present invention relates to body structure of industrial vehicle such as a fork lift, and more particularly relates to body structure suitable for a rear wheel drive, battery-operated, three-wheeled fork lift.
- Fig. 5 schematically shows a body structure of a conventional rear wheel drive, battery-operated, three-wheeled fork lift. The illustrated fork lift has a
drive unit 34 of the type vertically placing adrive motor 33 for driving a rear wheel, thedrive unit 34 being attached to the rear side of aframe 31 together with a powersteering oil motor 35 andcontroller 36. A large quantity of strengthening material such as athick steel plate 37 or rib is welded with the rear side of theframe 31 to secure a required strength for attaching such mechanical hardwares as thedrive unit 34 andcontroller 36. - Further, a
counterweight 32 is mounted on the rear end portion of theframe 31, thecounterweight 32 having a horizontal section in the form of a substantially U-shape so as to surround mechanical hardwares and strengthening material for supporting them. Such body structure is disclosed, for example, in Japanese Patent Laid-Open No. 62-36299 and Japanese Patent Laid-Open No. 5-24555. - In the above described conventional fork lift, since the
drive unit 34,oil motor 35,controller 36 etc. are attached to theframe 31, it is necessary, when mounting thecounterweight 32, to provide a predetermined gap between an inner surface of thecounterweight 32 and the mechanical hardwares and steel plate or the like for supporting them so as not to cause an interference thereof. Since, however, the counterweight in general is formed as a cast product, the production precision thereof is poor. For this reason, the gap for avoiding an interference tends to be set larger than that actually needed considering a margin of safety. - On the other hand, one of the characteristics of a three-wheeled, rear wheel drive fork lift is its compactness and capability of making a small turn. In order to fully use this characteristic, it is necessary to reduce the overall length of the vehicle as much as possible. For this reason, a rearward extension from the outer surface of the counterweight must be avoided. As described, the counterweight in the conventional three-wheeled, rear wheel drive fork lift has a constraint on its extension with respect to both the inner surface side and the outer surface side thereof. It has thus been very difficult to clear such constraint to obtain a required weight. Further, since a large quantity of strengthening material such as a thick steel plate or rib is welded with the rear portion of the frame, material cost and processing cost are increased to result in a problem of high cost.
- In view of the above described problems, it is an object of the present invention to provide a body structure of industrial vehicle capable of facilitating setting of the weight of a counterweight and at the same time suitable for achieving simplification of a rear portion of its frame.
- In a body structure of industrial vehicle where a drive unit for driving a rear wheel and a counterweight are disposed on the rear of the frame of the body, the body structure according to the present invention includes: a unit attaching portion formed on the counterweight mounted at a rear end portion of the frame; and a drive unit fixed to the unit attaching portion.

- Fig. 3 is a top view showing the layout of an upper side portion of the counterweight in the embodiment,
- Fig. 4 is a horizontal sectional view showing the layout of a lower side portion of the counterweight in the embodiment, and
- Fig. 5 schematically illustrates the body structure of a conventional three-wheeled, fork lift.
- An embodiment of the present invention will now be described in detail by way of the drawings. Referring to Fig. 1, a
counterweight 1 formed as a cast product includes arear portion 2 constituting a rear end portion of the vehicle and left andright side portions 3 monolithically extended frontward from therear portion 2 to constitute the two side portions of the rear end of the vehicle. Thecounterweight 1 is to be mounted on a rear end portion of the frame (not shown) of a fork lift. - The
rear portion 2 of thecounterweight 1 is formed into a substantially arch-like shape with the front surface side thereof being formed as a concave of the arch. The outer surface (rear surface) thereof is provided as a curved surface having a curvature approximated to the minimum turning clearance radius of the vehicle. Aunit attaching portion 4 for attaching adrive unit 11 is formed on the inner surface side of therear portion 2. Theunit attaching portion 4 is formed into the form of a plate extended substantially horizontally in a direction toward the front with having a required thickness substantially at the mid height on the inner surface of therear portion 2, the front end edge thereof reaching near the end surface of theside portions 3 and a substantially circular attaching hole vertically penetrating through substantially the center portion thereof. - As shown in Fig. 2, the
drive unit 11 to be attached to theunit attaching portion 4 includes: agear case 12; atire 13 rotatably attached to thegear case 12 around the horizontal axial line thereof; adrive motor 14 serving as a driving unit assembled in its vertical position with an upper portion of thegear case 12; an array of gears (not shown) contained in thegear case 12 and transmitting the driving force of thedrive motor 14 to thetire 13; and a substantially ring-like turning base 15 for rotatably supporting an upper end portion of thegear case 12 around a vertical axis thereof through a bearing (not shown). - Of the
drive unit 11, the members except thedrive motor 14 are attached to a lower surface of theunit attaching portion 4 of thecounterweight 1. That is, theunit attaching portion 4 has an attaching surface formed by the lower surface of the peripheral edge of the attachinghole 5, and theturning base 15 is detachably/reattachably tighten to the attaching surface with its upper surface abutting thereagainst by means of a plurality ofbolts 16 which are inserted from the upper surface side of theunit attaching portion 4. It should be noted that the attaching surface of theunit attaching portion 4 is processed into a horizontal plane, and the bolt holes to be formed on the attachingportion 4 are assured with their horizontal aspect by means of spot facing. - On the other hand, the
drive motor 14 is placed on an upper end surface of thegear case 12 through the attachinghole 5 from the top of theunit attaching portion 4, and a peripheral edge portion of an attachingflange 17 thereof is fixed detachably/reattachably to the upper end surface of thegear case 12 by means of a suitable number offixing bolts 18. That is, thedrive motor 14 of thedrive unit 11 is so constructed that it is detached/attached from the top of theunit attaching portion 4. In this manner, of thedrive unit 11, only theturning base 15 is fixed to thecounterweight 1 and the remaining members are provided as capable of a horizontal rotation for the purpose of steering. - In this manner, the
gear case 12 of thedrive unit 11 is attached from the lower surface side of theunit attaching portion 4 and thedrive motor 14 is attached to thegear case 12 from the upper surface side of theunit attaching portion 4 through the attachinghole 5. Thereby, rational assembling of thedrive unit 11 can be realized. - To secure an attaching space for the
fixing bolt 16 of theturning base 15 in the present embodiment, the portions corresponding to the bolt attaching positions of the inner peripheral edge of the attachinghole 5 are extended inwardly as shown in Fig. 3 to formprotuberances 5a. Further, in order to secure an attaching space of thefixing bolt 18 of thedrive motor 14,protuberances 17a are formed by outwardly extending the portions of the peripheral edge of the attachingflange 17 corresponding to the bolt attaching positions. - A predetermined gap is required between the end surface of the
hole side protuberance 5a and the end surface of theflange side protuberance 17a in order to avoid interference of theprotuberances drive unit 11. In this case, since dimensional precision of thecounterweight 1 formed as a cast product is poor, the end surface of thehole side protuberance 5a is processed after the forming of thecounterweight 1 to secure the required gap therefrom to theflange side protuberance 17a. - As a result of forming the
protuberances 5a on the inner periphery of the attachinghole 5 and forming theprotuberances 17a on the outer periphery of the attachingflange 17,recesses hole side protuberances 5a and between the neighboringflange side protuberances 17a. Accordingly, when thedrive motor 14 is to be detached or attached, the detaching/attaching operation may be readily performed by positioning in the peripheral direction as shown in Fig. 3 so that theprotuberances recesses - As shown in Fig. 4, a substantially block-like
motor attaching portion 6 for attaching anoil motor 19 for effecting power steering is formed on a lower side of the inner surface of oneside portion 3 of thecounterweight 1. Themotor attaching portion 6 is processed so that a vertical front surface thereof is provided as an attachingsurface 6a. Theoil motor 19 with its axis placed along a vertical direction is detachably and attachably fixed to the attachingsurface 6a at abase plate 20 thereof by means of fixingbolt 21. Asteering chain 24 is then extended over a drivingsprocket 22 on the motor shaft and a large-diameter follower rail 23 formed on the outer periphery of an upper portion of thegear case 12. It should be noted that a laterally extendedopening 8 is formed on therear portion 2 of thecounterweight 1 at a position suitable for the maintenance of thesteering chain 24. The opening is usually closed by a cover 9 which may be removed and reattached. - Further, as shown in Fig. 3,
controller attaching portions 7 for attaching acontroller 25 are formed on an upper portion of the front end surface of the left andright side portions 3 of thecounterweight 1. Thecontroller attaching portion 7 is processed so as to provide an attachingsurface 7a by its vertical front surface. Abase plate 26 of thecontroller 25 disposed in a manner extended left and right over the attachingsurfaces 7a is detachably and attachably fixed thereto by means of fixingbolts 27. - As described above, in the present embodiment, the
counterweight 1 is used as a rear frame by assembling such mechanical hardwares as thedrive unit 11,oil motor 19 andcontroller 25 with thecounterweight 1. Thereby, the rear portion of the frame in the fork lift requires no strengthening members and their welding such as a thick steel plate for attaching mechanical hardwares and ribs for reinforcing the same which have been required in the conventional construction. Thus, the rear portion of the frame is simplified in construction and a reduction in cost is achieved. - Further, when mounting the
counterweight 1 onto the rear portion of a frame, the conventional type where the mechanical hardwares are mounted on the frame side requires a gap to be provided in order to avoid interference with the mechanical hardwares and strengthening members for attaching them. Since, however, the above described gap need not be considered when employing the construction where the mechanical hardwares are attached to thecounterweight 1 as in the present embodiment, the constraint with respect to space is eliminated and at the same time it becomes possible to set the shape of the inner surface of thecounterweight 1 at will whereby weight adjustment may be readily performed. - In particular, since the
counterweight 1 may be designed as a single unit including thedrive unit 11,oil motor 19 andcontroller 25 to be attached thereto, the space efficiency thereof is improved so that a required weight may be readily obtained within a limited vehicle dimension (overall length and vehicle width). - In addition, a rational positioning of the
drive unit 11,oil motor 19 andcontroller 25 becomes possible by respectively providing theunit attaching portion 4 on a substantially center portion of the front surface of therear portion 2 of thecounterweight 1, themotor attaching portion 6 on a lower portion of the inner surface of one of theside portions 3 and thecontroller attaching portions 7 on an upper portion of the front surface of the left andright side portions 3. - Provided herein is a battery-operated, three-wheeled fork lift using a counterweight as its rear frame, thereby making weight setting of the counterweight easier and at the same time suitably achieving a simplification of the rear portion of the frame. A
unit attaching portion 4 extended substantially horizontally in a direction toward the front is formed on a front surface of arear portion 2 of thecounterweight 1 to be mounted on a rear end portion of the frame, and adrive unit 11 for driving a rear wheel is attached thereto. Further,controller attaching portions 7 are formed on an upper part of front surface of twoside portions 3 of thecounterweight 1, and acontroller 25 is attached thereto. Furthermore, amotor attaching portion 6 extended inwardly to provide an attaching surface by its front surface is formed on an inner surface of one of theside portions 3 of thecounterweight 1, and anoil motor 19 for power steering is attached thereto.
