[0001] Dispersion device for eccentric load of vehicle [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for distributing a biased load of a vehicle, and more particularly to an apparatus for distributing a biased load of a vehicle which is distributed to an opposite side of a biased load on a front portion or a rear portion of a vehicle body To a dispersing device.

In general, when a load is not loaded or loaded, or when the load is biased, the load on the vehicle body is concentrated when the occupant sits halfway to one side, which causes the vehicle body to tilt to one side, Concerns are high.

A conventional apparatus that has been developed in consideration of the biased load is disclosed in Korean Patent Publication No. 1999-010882. A control module for measuring a distance between the vehicle body and the ground by analyzing a sensed value input from the ultrasonic sensor, and a control module for controlling the entire body of the vehicle by controlling the control module And electronically controlled suspensions installed to evenly adjust the height.

Accordingly, the ultrasonic sensor senses the distance between the ground and the vehicle body, analyzes the sensed value by the control module, and measures the distance between the vehicle body and the ground. Then, the electronic control suspension evenly adjusts the height of the vehicle body.

However, the height of the body can not be adjusted artificially. Particularly, when the vehicle suddenly brakes, the entire body of the vehicle appears to be biased to an extremely heavy load. However, there is a problem that a simple suspension is not enough to solve the biased phenomenon.

KR19970033758 10

In order to solve the above-described problem, the present invention is devised to solve the above-mentioned problems, and it is an object of the present invention to provide a rear wheel and a rear wheel mounted on front and rear portions of the vehicle, And an object of the present invention is to provide a biased load distributing device for a vehicle in which a biased load generated by abrupt braking such as rapid braking is dispersed by distributing a biased load to an opposite portion by winding a winding member.

In order to achieve the above-mentioned object, an apparatus for balancing load distribution of a vehicle according to the present invention comprises: an axle housing capable of freely moving from a vehicle body by a suspension of a vehicle, or a fixed member mounted on wheels of front and rear wheels; A front wheel mounted opposite to a position at which the fixing member is mounted, the front wheel being a lower portion of the vehicle body and being mounted on the front portion or the rear portion; A rear wheel mounted to the stationary member and having an elongated rotating arm; A winding member which is installed on the front wheel and the rear wheel so as to have an infinite locus and is fixed to the stationary member at one side closer to the ground than the center point of the rear wheel; And a power source including a rod provided to rotate the rear wheel so as to move the rotary arm. When the rod is moved by the power source to move the rotary arm, the rear wheel rotates, The front wheel is rotated so that a part of the load biased to the front or rear of the vehicle body is dispersed to the opposite part through the winding member and the dispersed force is applied to the fixed member on one side of the wind- As shown in FIG.
In addition, when the rod is moved, when the engaging portion between the rod and the connecting shaft is moved, the connecting portion between the connecting shaft and the rotating arm is engaged with the engaging portion So that the rear wheel is rotated.

Here, the hoisting member is characterized by being one of a wire, a belt, and a chain.

Further, the power source is a hydraulic cylinder.

It is further characterized in that it further comprises a guide roller provided on a part of the winding member to provide tension to the winding member.

Further, in order to adjust the tension of the winding member, the other end of the winding member fixed to the fixing member is coupled to the one end through the buffer member.

Further, the present invention is further characterized in that the connecting member is provided at a joint portion between the connecting shaft and the rod so as to artificially operate the connecting shaft by operating the manual lever or the electronic switch of the driver.

Further, the front wheel, the rear wheel, the fixing member, the guide roller, the connecting shaft, the connecting member, and the power source are installed symmetrically or symmetrically with respect to the left side and the right side based on a state of being mounted on the driver's seat.

Further, the front wheel and the rear wheel are different in diameter.

Further, the front wheel is characterized in that its diameter is larger than that of the rear wheel.

The control unit may further include a control unit for operating the power source, the control unit including: a horizontal detection sensor installed to detect the horizontal position of the vehicle body; A solenoid operated by a signal of the horizontal detection sensor; A hydraulic regulating valve that is opened and closed by a solenoid; And a hydraulic line installed to supply the hydraulic oil supplied from the hydraulic pressure regulating valve to the power source to draw or insert the rod.

The control unit may further include a wheel rotation speed sensing sensor for sensing a rotation speed of each wheel of the vehicle. If the wheel rotation speed sensor detects that the rotation speed of any one of the wheels is different, The load of the vehicle is divided by winding or unwinding the rope by pulling or pulling the rod to adjust the tractive force of each wheel so that the rotational speed of each wheel is made constant and the left side And the vehicle load on the right side are individually adjusted.

The wheel rotation speed detection sensor may be included in the safety device of the vehicle such as ABS or may be installed separately. When the abnormality of the vehicle is detected, the wheel rotation speed detection sensor may output the data measured by the wheel rotation speed detection sensor together with the horizontal detection sensor 180 And the engine speed is also normalized when the rotational speed and the slope of the wheel are restored, and the engine speed is also normalized.

As described above, according to the present invention, the front wheel and the rear wheel provided at the front and rear portions of the vehicle lower portion are connected to the hoisting member, and the rear wheel winds and unwinds the hoisting member, To the opposite side thereof. Particularly, when the vehicle suddenly stops, the rear wheel is wound around the connecting member to distribute the suddenly biased load to the rear portion of the vehicle body, thereby increasing the contact force between the rear wheel and the road surface reduced instantaneously. It is possible to return to the normal mode. In this way, it is possible to minimize uneven rotation between each wheel, to increase the braking force, to prevent the overturning of the vehicle, and when the load is concentrated on any one wheel of the vehicle at the time of feeding, There is an effect of preventing the occurrence of the phenomenon.

In addition, the suddenly sudden and suddenly biased load in an unexpected situation is dispersed by an automatic dispersion system including a horizontal detection sensor, a hydraulic line and a hydraulic cylinder, and when the cargo is overloaded or unloaded, or when the occupant Or the rear portion can be dispersed in a manual dispersion manner operated by the driver and there is an effect of continuously dispersing until the biased load is removed.
Since the load distributing apparatus according to the present invention is separately operated regardless of various suspensions or electronic devices mounted on the vehicle, if the inclination of the vehicle body becomes severe, the grounding force of the vehicle wheel is lost due to the function limit of the suspensions or electronic devices It is possible to prevent a phenomenon and prevent an accident.

However, the detailed description of known functions and configurations incorporated herein will be omitted when it may unnecessarily obscure the subject matter of the present invention.

<Configuration>

FIG. 1 is a schematic view showing a device for distributing biased load distribution of a vehicle according to a preferred embodiment of the present invention, FIG. 2 is a configuration diagram showing only one side portion of the load distribution device shown in FIG. 1, 3 is an enlarged view of the rear wheel portion shown in Fig.

1 to 3, the apparatus for balancing the load distribution of a vehicle according to the present invention includes a fixed member 100, a front wheel 110, a guide roller 120, a rear wheel 130, a connecting shaft 140, a winding member 150, a power source, a connecting member 160, and a control unit. Hereinafter, the power source will be described by way of example of a hydraulic cylinder 170 for pulling out or inserting the rod 171. This power source may be replaced by a pneumatic cylinder in addition to the hydraulic cylinder 170, and one end of the connecting shaft 140 Any device capable of providing an external force for linear motion is possible. In addition, the distributing device operates the left front wheel, the rear right wheel, and the right front wheel and the rear wheel in cooperation with each other on the basis of a state of being onboard the driver's seat. That is, the front wheel 110 and the rear wheel 130 installed on the left and right rear wheels operate in conjunction with each other, and the front wheel 110 and the rear wheel 130 installed on the right and left rear wheels operate in conjunction. 1, the left and right structures may be arranged in the same manner, but the left and right structures may be symmetrically arranged to distribute the center of gravity of the vehicle. More specifically, when the front wheel 110 is installed on the entire left side, the rear wheel 130 is provided on the right side of the front side and the rear wheel 130 is provided on the front side of the rear wheel 130. Further, (160) and power sources are also installed symmetrically.

2 and 3, the fixing member 100 is mounted to the rear axle housing 101 of the vehicle, and the rear wheel 130 is rotatably fixed to the fixing member 100, and the rear wheel 130 The hydraulic cylinder 170 is fixed. Further, one side of the winding member 150 is fixed to the fixing member 100. A detailed description thereof will be given in the description of the wrap member 150 described later. Here, when the rear wheel 130 is symmetrically installed on the left and right sides of the vehicle according to the above-described symmetrical structure, the fixing member 100 is mounted on the rear axle housing 101 with the fixing member 100 on the left side of the vehicle , And on the right side of the vehicle are installed on the entire body of the vehicle. On the other hand, when the fixing member 100 is installed on the vehicle body at the left side of the vehicle, it is installed at the right side of the vehicle in the rear axle housing 101 of the vehicle.

1 and 2, the front wheel 110 is installed so as to be rotatable on the front side of the vehicle body, more specifically, on the lower side of the engine room. Here, the installation position of the front wheel 110 is a point of action of a force for moving the biased vehicle load, and the point of action of this force is the most efficient part for load distribution. Is most effective for weight dispersion. Of course, when the engine room is located at the rear portion of the vehicle and the portion subjected to the greatest load on the vehicle body is the rear portion of the vehicle, the front wheel 110 is installed on the vehicle body ahead of the front wheel, As the distance increases, the dispersion efficiency of the load increases more.

1 and 2, the guide roller 120 is installed to provide a pressure to the hoisting member 150 to maintain a constant tension on the hoisting member 150 at a portion where the front wheel 110 is installed. The guide roller 120 may be installed at a suitable position other than the vicinity of the front wheel 110 to avoid interference between the winding member 150 located at the lower portion of the vehicle body and other accessories.

The rear wheel 130 is rotatably fixed to the rear portion of the vehicle body, more specifically, to the fixed member 100 mounted on the rear axle housing 101. [ The rear wheel 130 is formed with a rotary arm 131 protruding and extending. The free end of the rotary arm 131 is connected to be rotated by the hydraulic cylinder 170. Accordingly, when the hydraulic cylinder 170 rotates the rotary arm 131, the rear wheel 130 also rotates and the rear wheel 130 winds the winding member 150 at an angle that the rear wheel 130 rotates. The diameter of the rear wheel 130 and the diameter of the front wheel 110 are made different from each other so that the winding member 150 can be wound with a minimum force. For example, the diameter of the front wheel 110 is larger than that of the rear wheel 130.

The connection shaft 140 is interposed between the rotary arm 131 and the hydraulic cylinder 170 and is a member for converting the linear motion of the rod 171 of the hydraulic cylinder 170 into the rotary motion of the rotary arm 131. One end of the connecting shaft 140 is mounted on the free end of the rotary arm 131 and the other end is mounted on the end of the rod 171 of the hydraulic cylinder 170. When the rod 171 of the hydraulic cylinder 170 linearly moves to move one end of the connection shaft 140 in a linear direction, the other end of the connection shaft 140 moves upward and downward, . For example, when the connecting portion between the one end of the connecting shaft 140 and the rod 171 of the hydraulic cylinder 170 is moved to the left or right, the other end of the connecting shaft 140 and the connecting portion between the rotating arm 131 The rear wheel 130 is rotated while moving up and down. As a result, the rear wheel 130 can wind the hoisting member 150, and a load biased toward the front of the vehicle through the hoisting member 150 moves to the rear of the vehicle, and the movement of the force is transmitted to the hoist member 150 Described in the description. At this time, the other end of the connecting shaft 140 and the coupling portion of the rotary arm 131 are rotated about the coupling portion between the one end of the connection shaft 140 and the rod 171 of the hydraulic cylinder 170, The rotational angle of the rotary arm 131 is determined according to the axial rotation angle. The degree of winding of the winding member 150 according to the rotation angle of the rear wheel 130 rotating together with the rotary arm 131 is determined and a size for dispersing the loads of the front and rear parts of the vehicle It is decided.

As shown in FIGS. 2 and 3, the hoist member 150 is wound around the front wheel 110 and the rear wheel 130 so as to form an infinite locus. One end of the hoop member 150 is fixed to the fixing member 100, And is mounted at one end thereof with a buffer member 151 interposed therebetween. here,
Thus, the hoist member 150 is wound on the rear wheel 130 rotated by the hydraulic cylinder 170 to be tensed, and the load concentrated on the front wheel 110 side is forcedly distributed to the rear wheel 130 side And the load concentrated on the rear wheel 130 side is forcefully dispersed toward the front wheel 110 side. That is, in order to forcefully distribute the biased load, the winding member 150 is forcibly wound around the rear wheel 130 to be tense so that the biased load on the front wheel 110 or the rear wheel 130 is forcedly dispersed . For example, when the vehicle suddenly brakes, the load is severely centered on the entire body of the vehicle. At this time, when the rear wheel 130 winds the winding member 150, the load concentrated on the entire body is forcibly dispersed to the rear portion.
More specifically, a winding member 150 having one side fixed to the fixing member 100 in a state of being wound around the front wheel 110 and the rear wheel 130 is formed with a substantially triangular support point. At this time, the supporting point of the triangle is formed because the hoisting member 150 is fixed to the fixing member 100 at a position closer to the ground than the rotation center of the rear wheel 130.
Accordingly, the rear wheel 130 rotates and turns around the winding member 150 to generate a force. The front wheel 110 is a point of action of the force, and the front wheel 110 rotates the winding member 150 The point of receiving the force transmitted through the fixing member 100 becomes the fixing member 100, i.e., the coupling portion between the fixing member 100 and the winding member 150. [
The linkage structure of the front wheel 110, the rear wheel 130 and the hoisting member 150 will be described by way of example. When the load of the vehicle is suddenly biased in a sudden stop state, the hoisting member 150 is wound on the rear wheel 130 rotated by the hydraulic cylinder 170 so that the hoisting member 150 is biased toward the front of the vehicle The load can be forcefully dispersed to the fixing member 100 by the force mobility law using the winding member 150 as a force moving means while making the front wheel 110 a point of force. The movement of the force is finally transmitted to the rear wheel 30 via the fixing member 100, the rear axle housing 101 and the rear axle shaft so that the rear wheel 30 moves downward to increase the contact force with the ground . The rear axle housing 101 having the front wheel 110 fixed to the vehicle body and the rear wheel 130 fixed is connected to the coil spring 32 of the rear suspension 31 to be freely movable from the vehicle body And the supporting points of the triangle of the front wheel 110, the rear wheel 130 and the fixing member 100, it is possible to move the force by the force mobility law.
Here, the winding member 150 is preferably a wire, and in addition, a belt or chain may be used. Of course, depending on the kind of the hoisting member 150, parts corresponding to the hoisting member 150 are also applied to the front wheel 110 and the rear wheel 130. [
Here, the cushioning member 151 keeps both ends of the winding member 150 engaged with each other while the winding member 150 is forcibly wound on the rear wheel 130. In addition, when the tension member 150 is used for a long time and its tension is relaxed, the buffer member 151 may be adjusted to an initial tension state.
The cushioning member 151 of the cushioning member 151 is coupled to one end of the winding member 150 forming the endless track in a state where the front wheel 110 and the rear wheel 130 are wound, It is a member that keeps the state. More specifically, the cushioning member 150 is connected to the cushioning member 150 at one end and the other end thereof, and the cushioning member 150 is connected to the cushioning member 151 ). &Lt; / RTI &gt; That is, due to the structure in which one side portion of the winding member 150 is fixed to the fixing member 100 and one end portion and the other end portion of the winding member 150 are held by the cushioning member 150, The movement of the generated force as the member 150 is wound on the rear wheel 130 can be transmitted to the fixing member 100 completely and the force transmitted to the fixing member 100 is transmitted to the rear axle housing 101 and the rear axle 100. [ And transmitted to the rear wheel 30 fastened to the rear axle shaft through the shaft. This force movement is such that a biased load on the front side of the vehicle moves to the rear of the vehicle and is finally transmitted to the rear wheel 30, thereby moving the rear wheel 30 downward, thereby raising the contact force with the ground.

The hydraulic cylinder 170, which is an example of a power source, is installed to provide an external force to the connecting shaft 140 by being connected to one end of the connecting shaft 140. In addition, the hydraulic cylinder 170 is configured such that the rod 171 is drawn or inserted by the hydraulic pressure introduced through the hydraulic line 210 as shown in FIG. The hydraulic cylinder 170 is mounted to the fixing member 100 of the rear axle housing 101 as shown in Fig. Here, a pneumatic cylinder may be used instead of the hydraulic cylinder 170, in which the hydraulic line 210 is replaced by a pneumatic line. The power source may be any device that provides an external force so that one end of the connection shaft 140 can perform linear motion.

The connecting member 160 is provided for the operator to artificially disperse the biased load of the vehicle body, and is connected to a manual control device (for example, a lever) or an electronic switch that can be operated by the driver. The connecting member 160 is moved by a manual adjusting device or an electronic switch to provide an external force to the connecting shaft 140 instead of the rod 171 of the hydraulic cylinder 170. 3, the connecting member 160 is installed at a point where the rod 171 of the hydraulic cylinder 170 and the connecting shaft 140 are coupled to each other and is connected to the connecting shaft 140 while linearly moving as the rod 171, As shown in Fig. Accordingly, when the connecting member 160 is moved along the moving direction of the rod 171, the connecting shaft 140 moves upward and downward. When the rotating arm 131 is moved by this movement, the rear wheel 130 .
On the other hand, when the front wheel 110 is fixed to the rear axle housing 101 of the vehicle and the rear wheel 130, the fixing member 100, the power source, the connecting shaft 140, So that the load biased to the rear of the vehicle can be distributed to the front of the vehicle. It may also be installed on the left side and the right side, respectively, based on the state of boarding the driver's seat. In this case, the left and right sides of the vehicle may be arranged so as to distribute the biased load to the opposite portion in the same direction and to the front or rear of the vehicle, or may be arranged so that the left and right sides are mutually opposite directions, To the opposite site.

As shown in FIG. 1, the control unit includes a horizontal detection sensor 180, a solenoid 190, a hydraulic control valve 200, and a hydraulic line 210. In addition, the control unit may be a conventional control unit including an anti-lock brake system (ABS), an electronic brake force distribution (EBD), an electronic stability program (ESP), an automatic braking differential (ABD), a vehicle dymanic control It is installed in connection with the vehicle safety device and distributes the load of the vehicle according to the ground condition of the road surface and each wheel. For example, when a wheel rotation speed sensor (not shown) installed in a vehicle safety device detects a rotation speed of each of the wheels and a control unit are connected to each other and a difference in rotation speed of each wheel is sensed by the wheel rotation speed sensor It is determined that the ground state of the road surface and the front and rear wheels are different from each other, and the load of the vehicle is distributed through the hoisting member 150 to adjust the ground state of the wheels with respect to the road surface. That is, when it is determined that the ground state of the front and rear wheels is different or the ground state of the left and right wheels is different on the basis of the state of boarding the driver's seat, the hydraulic cylinder 170 is operated, The member 150 is wound to distribute the load of the vehicle to adjust the grounding state of the wheels on the road surface. For example, when the left front wheel falls off the road surface and the rotational speed is faster than the rotational speed of the left rear wheel, it is judged that the left front wheel is less in contact force than the rear wheel 30 and the left wind member 150 is wrapped, So that the grounding force is increased. Alternatively, when the rotational speed of each wheel is different in a situation where the rotational speed of each wheel is different in a situation where the rotational speed of each wheel is different from that of a beating path, a snow path, or a puddle, the winding member 150 is wound to distribute the left or right load to the front portion or the rear portion, Minimize the rotational speed difference of each wheel. Of course, the distribution of loads according to the present invention operates in conjunction with existing safety devices. On the other hand, the wheel rotation speed sensor can be independently operated independently of the existing vehicle safety device.

First, the horizontal detection sensor 180 is installed to operate the solenoid 190 when the horizontal level of the vehicle body collapses due to a biased load. Here, the horizontal detection sensor 180 is installed to detect the angle of the vehicle body that deviates in the horizontal direction and to control the operation time of the solenoid 190. The horizontal detection sensor 180 is, for example, a gyro sensor. The data measured by the horizontal detection sensor 180 and the wheel rotation speed sensor are collected and analyzed at the same time that an abnormality of the vehicle is detected and the front wheel 110 A rear wheel 130, a hoisting member 150, and a power source. At this time, in addition to the collection and analysis of the measurement data, the fuel supply of the engine is regulated to decelerate the engine speed. After the load of the vehicle is distributed, when the level of the vehicle and the rotational speed of each wheel return to normal, Return to normalize engine speed.

The solenoid 190 is installed to apply and short-circuit the power according to the operation signal received by the horizontal detection sensor 180 and to control the open / close, open angle and open time of the hydraulic control valve 200.

The hydraulic pressure regulating valve 200 receives the control signal of the solenoid 190 and is opened or closed according to the supply direction, the supply amount and the supply time of the hydraulic oil according to the control signal. The drawing or insertion of the rod 171 is determined by the feeding direction of the hydraulic oil supplied by the opening and closing of the hydraulic control valve 200 and the length of the rod 171 drawn or inserted according to the feeding amount and feeding time of the hydraulic oil After a certain period of time, it is determined whether or not to return.

The hydraulic line 210 is provided to supply the hydraulic oil supplied from the hydraulic pressure regulating valve 200 to the hydraulic cylinder 170 and more specifically to the hydraulic cylinder 170. Hydraulic oil is supplied to both sides of the piston built in the hydraulic cylinder 170 . Accordingly, the piston moving direction of the hydraulic cylinder 170 is determined according to the supply direction of the hydraulic oil, and the rod 171 is drawn or inserted according to the moving direction of the piston. Further, the drawing length of the rod 171 is determined according to the supply amount of the hydraulic oil.

The load distributing apparatus having such a configuration may automatically disperse the load biased by the control unit including the horizontal detecting sensor 180 or may distribute the manually biased load through the connecting member 160 by the driver. In a more specific example, in the case of automatic dispersion, a suddenly biased load can be forcedly distributed to the rear portion of the vehicle body at the time of sudden braking of the vehicle. In the case of passive dispersion, when a heavy load is loaded on the rear portion of the vehicle and the driver recognizes that one side of the vehicle body is lower or higher than the other side, the connecting member 160 is operated through the manual lever, It is possible to forcibly disperse the load concentrated on the whole.

As described above, those skilled in the art will appreciate that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included within the scope of the present invention.
