Background
A general vehicle equipped with a manual transmission includes a device called a clutch, which is provided between a flywheel and an input shaft of the transmission, and connects/disconnects power transmitted from an engine to the transmission as necessary.
For shifting, the driver first disengages the clutch device in the vehicle by depressing the clutch pedal, then shifts to a desired gear by manipulating the shift lever, and reconnects the clutch device by releasing the depressed clutch pedal, thereby completing the shift.
According to the hydraulic clutch system including the clutch master cylinder and the clutch release cylinder between the clutch pedal and the clutch device, when the driver depresses the clutch pedal, the sum of the elastic force provided in the clutch pedal and the hydraulic pressure generated by the clutch master cylinder and the clutch release cylinder becomes a response force (reaction force).
On the other hand, the electronic clutch system is advantageous in that weight and manufacturing cost can be significantly reduced compared to the hydraulic clutch system because it does not use a mechanical structure using hydraulic pressure. Therefore, when the driver depresses the clutch pedal to shift gears, a pedal sensor on the clutch pedal detects the degree of depression (rotation angle) of the clutch pedal and transmits the detected value as an electric signal to a controller (clutch controller, electronic controller for operating the clutch), the controller receives various signals including the signal from the pedal sensor and the number of revolutions of the engine, automatically calculates an optimum operation time of the clutch for the vehicle state, and controls the operation of an actuator (means for connecting/disconnecting the clutch, DC motor, etc.), and the clutch means is connected or disconnected by the operation of the actuator.
Meanwhile, a clutch pedal device for an electronic clutch system includes: an engagement device (snap) that engages when a driver depresses a clutch pedal; and a restoring force generating device that provides a restoring force to the clutch pedal rotated forward. In particular, in this structure, the restoring force generating means employs a spring having a very strong elastic force to smoothly restore the clutch pedal.

Detailed Description
A clutch pedal apparatus for an electronic clutch system according to an exemplary embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 18, a clutch pedal device for an electronic clutch system according to the present disclosure includes: a pedal member 100 fixed to a vehicle body panel (instrument panel) in front of the driver seat; and a clutch pedal 300 rotatably coupled to the pedal member 100 forward and backward by the hinge shaft 210 and the connection pin 220.
The pedal member 100 has the following structure: the front portion is joined to a vehicle body panel (instrument panel), and two side portions extending rearward from the front portion are parallel and open rearward, upward, and downward.
Namely, the pedal member 100 has: a front portion 110 bonded to a vehicle body panel (instrument panel); and two side portions 120 protruding rearward from left and right sides of the front portion 110 and parallel to each other, and the pedal member 100 is opened upward, downward and rearward.
A coupling hole 130 having a slit shape is formed on each of the two side portions 120 of the pedal member 100. Coupling holes 130 having a slit shape are formed in the same shape at both side portions 120 of the pedal member 100 and are located in front with respect to the hinge shaft 210 coupled to the pedal member 100.
The hinge shaft 210 is coupled to the connection pin 220 laterally sequentially through both side portions 120 of the pedal member 100 and the upper end portion of the clutch pedal 300, so that the clutch pedal 300 is coupled to be capable of rotating forward/backward about the hinge shaft 210 with respect to the pedal member 100.
The upper end of the clutch pedal 300 is a portion through which the hinge shaft 210 passes, and the lower end of the clutch pedal 300 has a pad 310 operated by the foot of the driver.
The upper end of the clutch pedal 300 is formed with a stopper protrusion 320 protruding forward.
The clutch pedal device according to the present disclosure further includes: an engagement device 400 that is engaged when the driver depresses the clutch pedal 300 (when the clutch pedal rotates forward about the hinge shaft); and a restoring force generating means 500 providing a restoring force to the clutch pedal 300 rotated forward to rotate the clutch pedal 300 backward for restoration.
The clutch means 400 is provided inclined forward below the hinge shaft 210 coupled to the clutch pedal 300, the clutch means 400 is coupled to the clutch pedal 300 and a lower portion of the clutch means 400 is in contact with the friction surface 140 of the pedal member 100, thereby being engaged by contact with the friction surface 140 when the clutch pedal 300 is operated.
The occluding device 400 comprises: an engagement spring 410 composed of a compression coil spring; a spring seat 420 inserted into the guide groove 340 formed on the clutch pedal 300 and supporting a first end of the click spring 410; a roller housing 430 provided movably along the guide groove 340 and supporting a second end of the engaging spring 410; and a rotating roller 440 rotatably coupled to the roller housing 430 and contacting the friction surface 140 of the pedal member 100.
The friction surface 140 of the pedal member 100 is a curved groove formed along a specific contour (profile). When the clutch pedal 300 is operated, the roller housing 430 and the rotation roller 440 contacting the friction surface 140 are moved along the guide groove 340 of the clutch pedal 300, and the biting spring 410 is compressed or restored by the movement of the roller housing 430, so that the biting occurs by the contact of the friction surface 140 of the pedal member 100 with the rotation roller 440.
The bite occurring when the clutch pedal 300 is operated can be adjusted by changing the shapes of the friction surface 140 and the rotating roller 440 of the pedal member 100.
The restoring force generating device 500 is provided such that both ends thereof are connected to the clutch pedal 300 and the pedal member 100 in front of the hinge shaft 210 coupled to the clutch pedal 300. Accordingly, when the clutch pedal 300 is rotated forward, the restoring force generating means 500 is compressed and accumulates elastic force, thereby providing restoring force to the clutch pedal 300 using the accumulated elastic force, so that the clutch pedal 300 can be rotated backward to be restored.
The restoring force generating means 500 and the pedal member 100 are assembled by the fitting structure of the protrusion and the hole, and thus the restoring force generating means 500 can be easily and conveniently assembled to the pedal member 100 without using a rivet or a bolt and a nut as in the prior art. Therefore, there is an advantage that convenience of assembly work and productivity can be improved.
The coupling holes 130 are formed in both side portions 120 of the pedal member 100 in a slit shape with both ends thereof cut forward and backward, and the coupling protrusions 521 are formed on the restoring force generating means 500. Accordingly, the coupling protrusion 521 is fitted in the coupling hole 130, so that one end of the restoring force generating apparatus 500 is assembled to the pedal member 100 by the fitting structure of the protrusion and the hole.
The restoring force generating device 500 is located in front of the clutch pedal 300, the coupling protrusion 521 at the upper end of the restoring force generating device 500 is fitted in the coupling hole 130 of the pedal member 100, and the lower end of the restoring force generating device 500 is connected to the front of the clutch pedal 300.
The restoring force generating apparatus 500 includes: a restoring spring 510 comprising one or two compression coil springs; a top seat 520 having two coupling protrusions 521 protruding in opposite directions to be fitted in the coupling holes 130 of the pedal member 100, and supporting the upper end of the restoring spring 510; and a base 530 having a guide rod 531 disposed to pass through the restoring spring 510, and supporting a lower end of the restoring spring 510 and coupled to a front portion of the clutch pedal 300.
A guide hole 522 extending up and down is formed on the top chassis 520, and the upper end of the guide rod 531 is partially inserted into the guide hole 522. Accordingly, when the guide rod 531 moves in the guide hole 522, the restoring spring 510 is compressed or restored, and thus the gap between the top seat 520 and the bottom seat 530 is variably adjusted.
The top mount 520 and the bottom mount 530 are coupled in a snap fit (snap fit) configuration. For this, a fastening hole 523 of a slit shape extending up and down is formed at a portion where the guide hole 522 is formed, and a fastening protrusion 532 having a triangular cross-section is formed on the guide bar 531 of the base 530 to be inserted into the fastening hole 523.
The base 530 and the clutch pedal 300 are also coupled in a snap-fit configuration. To this end, a cylindrical protrusion 533 is formed on the base 530, and an arc-shaped coupling part 330 is formed on the front of the clutch pedal 300, the cylindrical protrusion 533 being inserted into the arc-shaped coupling part 330 in one touch.
According to the embodiment of the present disclosure, when the driver steps on the clutch pedal 300 and the clutch pedal 300 rotates forward about the hinge shaft 210, the biting-in occurs by the contact between the friction surface 140 of the pedal member 100 and the rotation roller 440. Further, when the clutch pedal 300 is operated, the engaging spring 410 and the restoring spring 510 are compressed and accumulate elastic force, and the sum of the compression elastic force of the engaging spring 410 and the compression elastic force of the restoring spring 510 generated in the process becomes a response force (reaction force, operation force).
When the driver releases the clutch pedal 300 rotated forward by removing the foot, the clutch pedal 300 is rotated backward and restored to the original position by the restoring force of the restoring spring 510, and in the process, a value obtained by subtracting the frictional force generated by the contact between the friction surface 140 and the rotating roller 440 from the sum of the restoring force of the engaging spring 410 and the restoring force of the restoring spring 510 is used as the restoring force of the clutch pedal 300. Therefore, the present disclosure is characterized in that the frictional force generated by the contact between the frictional surface 140 and the rotating roller 440 when the clutch pedal 300 is restored rearward serves as a resistance, thereby generating hysteresis (hystersis).
According to a general clutch pedal device for an electronic clutch system, when a driver depresses a clutch pedal, a response force (reaction force) is generated by only one elastic force of the clutch pedal device. Therefore, compared to the hydraulic clutch system, hydraulic pressure is not included in the response force (reaction force), so inconvenience is brought about due to sense of deviation (sense of disengagement).
However, the clutch pedal device for the electronic clutch system according to the present disclosure is configured such that the sum of the compression elastic force of the engaging spring 410 and the compression elastic force of the restoring spring 510, which are generated when the clutch pedal 300 is operated, serves as the response force (reaction force) of the clutch pedal 300. Therefore, compared to a hydraulic clutch system, there is an advantage in that the same level of response force (reaction force) is generated, and thus the sense of difference can be eliminated, thereby significantly improving commercial value.
According to an embodiment of the present disclosure, a stopper protrusion 320 protruding forward is formed at an upper end of the clutch pedal 300, and a stopper 620 made of rubber is installed between both side portions 120 of the pedal member 100 by a stopper pin 610 provided to pass through both side portions 120 of the pedal member 100. Therefore, when the clutch pedal 300 is rotated backward about the hinge shaft 210 to be restored, the stopper 620 is contacted with the stopper protrusion 320, and thus the backward restored position 300 of the clutch pedal 300 is restricted.
The stopper pin 610 passes through both side portions 120 of the pedal member 100, and then the nut 630 is fastened to the stopper pin 610, thereby preventing the stopper pin 610 from being separated from the pedal member 100.
The embodiment of the present disclosure further includes a pedal sensor 700, the pedal sensor 700 being coupled to one side of the pedal member 100 and connected to the clutch pedal 300, detecting a rotation amount of the clutch pedal 300 according to an operation of the clutch pedal 300, and outputting a signal to the clutch controller.
The pedal sensor 700 may include a permanent magnet and a Printed Circuit Board (PCB). The permanent magnet is connected to the clutch pedal 300 such that the position of the permanent magnet changes when the clutch pedal 300 rotates. The PCB is fixed to the case of the pedal sensor 700 to face the permanent magnet. In addition, the PCB is electrically connected to a power supply device such as a battery through a wire.
When the clutch pedal 300 is rotated by the operation of the driver, the position of the permanent magnet is changed with the rotation of the clutch pedal 300. At this time, the PCB detects a change in magnetic flux according to a change in position of the permanent magnet and outputs a signal to the clutch controller, the clutch controller receives the signal output from the PCB and controls the operation of the clutch actuator, and the clutch is disconnected or connected by the operation of the clutch actuator, thereby electrically performing clutch control.
The clutch of the vehicle is the same as a general structure including a flywheel connected to a crankshaft, a clutch plate, a pressure plate, a clutch spring, a release lever, a release bearing, a release fork, etc., and thus will not be described in detail herein.
Embodiments of the present disclosure further include a pedal switch 800 coupled to a second side of the pedal member 100. The pedal switch 800 functions as an integrated sensor, and can perform all functions of the clutch switch, the ignition lock switch, and the stroke sensor for the EPB, and thus has an advantage that the cost can be reduced.
The slit-shaped coupling hole 130 formed on the pedal member 100 has a structure in which one end and the other end are spaced apart from each other in the front-rear direction. Specifically, one end of the front portion of the coupling hole 130 is higher than the other end of the rear portion. The coupling protrusion 521 of the restoring force generating apparatus 500 is fitted in the coupling hole 130 and is located at one end of the front.
When the coupling protrusion 521 of the restoring force generating apparatus 500 is fitted in the coupling hole 130 of the pedal member 100, an upward force is applied to the top seat 520 of the restoring force generating apparatus 500 by the elastic force of the restoring spring 510. In this case, since one end of the front portion of the coupling hole 130 is higher than the other end of the rear portion, the coupling protrusion 521 fitted in the coupling hole 130 is prevented from being separated and moved, and can be rotated only when the clutch pedal 300 is rotated.
According to an embodiment of the present disclosure, as shown in fig. 9, the slit-shaped coupling hole 130 formed on the pedal member 100 may be a straight hole 131 linearly inclined from the front end to the rear end.
The straight hole 131 is most advantageous in combination with the combination protrusion 521, is advantageous in preventing the restoring force generating means 500 from being moved when the clutch pedal 300 is operated, and is advantageous in strength because the straight hole 131 has a closed structure.
As another example, as shown in fig. 10, the slit-shaped coupling hole 130 formed on the pedal member 100 may be a straight hole 131 inclined from the front end to the rear end, and a slit-shaped coupling hole 132 may be formed to couple the straight hole 131 to the outside of the pedal member 100. In this case, the connection hole 132 may be connected to the rear end of the straight hole 131 and may be opened upward through the top of the pedal member 100.
The coupling hole 130 shown in fig. 10 has a structure in which the rear end of the straight hole 131 is upwardly opened through the coupling hole 132, and thus is advantageous in assembling the coupling protrusion 521 due to the coupling hole 132, and is advantageous in preventing the restoring force generating means 500 from being moved due to the operation of the clutch pedal 300.
As another example, as shown in fig. 11, the slit-shaped coupling hole 130 formed on the pedal member 100 may be a straight hole 131 linearly inclined from the front end to the rear end, and a slit-shaped connection hole 133 may be formed to connect the straight hole 131 to the outside of the pedal member 100. In this case, the connection hole 133 may be connected to a middle between one end and the other end of the straight hole 131, and opened upward through the top of the pedal member 100.
The coupling hole 130 shown in fig. 11 has a structure in which the middle of the straight hole 131 is opened upward through the coupling hole 133, and thus is advantageous in assembling the coupling protrusion 521 due to the coupling hole 133, and is advantageous in preventing the restoring force generating means 500 from being moved due to the operation of the clutch pedal 300.
As another example, the slit-shaped coupling hole 130 formed on the pedal member 100 may be any one of a downwardly curved hole 134 protruding downward at the middle between the front and rear ends as shown in fig. 12 and an upwardly curved hole 135 protruding upward at the middle as shown in fig. 13.
The downward arc-shaped hole 134 shown in fig. 12 and the upward arc-shaped hole 135 shown in fig. 13 have a disadvantage in that it is slightly disadvantageous in assembling the coupling projection 521 as compared with the structure having the coupling hole, but is advantageous in strength because it has a closed structure, and is particularly advantageous in preventing the restoring force generating means 500 from being moved when the clutch pedal 300 is operated.
As another example, as shown in fig. 14, the slit-shaped coupling hole 130 formed on the pedal member 100 may have a slit-shaped coupling hole 136 coupling a downward arc-shaped hole 134 to the outer side of the pedal member 100. In this case, the connection hole 136 may be connected to a rear end of the downward arc hole 134 and opened upward through the top of the pedal member 100.
The coupling hole 130 shown in fig. 14 has a structure in which the rear end of the downward arc-shaped hole 134 is upwardly opened through the coupling hole 136, and thus, is advantageous in assembling the coupling protrusion 521 due to the coupling hole 136, and is advantageous in preventing the restoring force generating means 500 from being moved due to the operation of the clutch pedal 300.

Next, the restoring force generating means 500 inserted into the space between the two side portions 120 of the pedal member 100 is rotated clockwise or counterclockwise (arrow R1) by 90 degrees to turn the two coupling protrusions 521 facing forward and backward to the left and right and inserted into the coupling holes 130 formed at the two side portions 120 of the pedal member 100.
After the coupling protrusion 521 is inserted into the coupling hole 130 as shown in fig. 16, the restoring force generating device 500 is turned upside down (arrow R2) around the coupling protrusion 521 as shown in fig. 17 such that the base 530 is located below the top seat 520, and then the clutch pedal 300 is rotatably coupled to the pedal member 100 around the hinge shaft 210 as shown in fig. 18, and the arc-shaped protrusion 533 of the base 530 is fitted into the arc-shaped coupling part 330 of the front of the clutch pedal 300. Accordingly, the upper end of the restoring force generating device 500 is coupled to the pedal member 100 by the assembly of the coupling protrusion 521 and the coupling hole 130, and the lower end of the restoring force generating device 500 is coupled to the clutch pedal 300 by the assembly of the arc protrusion 533 and the arc coupling part 330.
As described above, the clutch pedal device for an electronic clutch system according to the embodiment of the present disclosure includes the biting means 400, which is engaged when the driver steps on the clutch pedal 300, and the restoring force generating means 500, which provides the restoring force to the clutch pedal 300 rotated forward, wherein the restoring force generating means 500 having a large spring force is assembled without using rivets or bolts and nuts, and can be easily and conveniently assembled by assembling the coupling holes 130 formed on the pedal member 100 and the coupling protrusions 521 formed on the restoring force generating means 500 to each other. Therefore, there is an advantage that convenience of assembly work and productivity can be improved.
Although the present disclosure has been described with reference to the specific embodiments shown in the drawings, it will be apparent to those skilled in the art that the present disclosure may be changed and modified in various ways without departing from the scope of the present disclosure described in the claims.
