Disclosure of Invention
Problems to be solved by the invention
In the above-described conventional mechanical brake device, when detecting the operation amount of the brake pedal, an arm member that rotates in conjunction with the rotation of the brake pedal is provided, and the rotation angle of the arm member is detected by a rotation angle sensor, so that the operation amount of the brake pedal can be detected.
However, in the above method, it is necessary to attach an arm member and a rotation angle sensor to the periphery of the brake pedal. In particular, in a handlebar type vehicle, since the brake pedal is exposed to the outside, a cover for protecting the rotation angle sensor is also required. As described above, in the conventional mechanical brake device, when the operation amount of the brake pedal is detected, there is a problem in that the number of parts of the brake device increases.
The present invention addresses the above-described problem, and provides a vehicle brake device that can reduce the number of components and detect the amount of operation of a brake operating element.
Means for solving the problems
In order to solve the above problem, the present invention provides a vehicle brake device including: a wheel brake having a pair of brake shoes housed within the drum; an input lever rotatably coupled to an outer surface of the drum; and an operation amount detection device that detects an operation amount of the input lever. The input lever is rotated in conjunction with the rotation of the brake operating member, thereby enlarging the interval between the two brake shoes. At least a part of the operation amount detecting device is housed in the drum, and includes a rotation angle sensor for detecting a rotation amount of a support shaft of the input lever inserted in the drum.
In the vehicle brake device according to the present invention, the amount of rotation of the input lever can be detected without mounting a rotation angle sensor around the brake operating element or on the outer surface of the wheel brake, and therefore the number of components of the brake device can be reduced.
In the vehicle brake device, the support shaft is preferably inserted into an insertion hole penetrating through a side wall of the drum. In this case, it is preferable that the operation amount detection device includes: a bearing portion fitted into the insertion hole; and the rotation angle sensor attached to an outer ring of the bearing portion. Preferably, the support shaft is inserted into an inner ring of the bearing portion, and the rotation angle sensor detects a rotation amount of the inner ring of the bearing portion.
In this way, by housing the operation amount detection device in which the bearing portion and the rotation angle sensor are integrated in the insertion hole of the drum, the operation amount detection device can be arranged compactly with respect to the wheel brake. Further, since the rotation angle sensor is disposed by using the insertion hole for inserting the support shaft of the input lever, it is not necessary to perform a process of attaching the rotation angle sensor to the drum.
In the vehicle brake device, the support shaft is preferably inserted into an insertion hole penetrating through a side wall of the drum. In this case, it is preferable that the operation amount detection device includes: a common rotating member fitted to an outer periphery of the support shaft; and the rotation angle sensor that is disposed between the outer surface of the drum and the input rod, is attached to the outer periphery of the co-rotating member, and is at least partially housed in the insertion hole. Further, it is preferable that the rotation angle sensor detects a rotation amount of the co-rotating member.
In this way, by housing at least a part of the rotation angle sensor in the insertion hole, the operation amount detection device can be disposed compactly with respect to the wheel brake, and an increase in size of the brake device can be suppressed. Further, by disposing the rotation angle sensor between the outer surface of the drum and the input lever, the rotation angle sensor can be protected.
The vehicle brake device may be provided with an electronic control device having a braking force calculation unit that estimates a braking force generated at the wheel brake based on a rotation amount of the input lever. In this configuration, the braking force generated at the wheel brake can be detected without providing a tension sensor to the input rod or the brake cable, and therefore the number of components of the wheel brake can be reduced.
In the vehicle brake device, it is preferable that the electronic control unit stores braking force data indicating a relationship between the amount of rotation of the input lever and the braking force. In this case, the braking force calculation unit preferably estimates the braking force based on the braking force data. In this configuration, the braking force corresponding to the rotation amount of the input lever detected by the operation amount detecting device can be calculated from the braking force data.
In the vehicle braking device, the electronic control unit is provided with a determination unit that determines an adjustment state of the wheel brake, and the determination unit determines the adjustment state of the wheel brake based on whether or not the braking force generated by the wheel brake is within a predetermined amount of the braking force in the braking force data.
In the vehicle brake device, the electronic control unit may be provided with a brake lamp control unit that turns on a brake lamp based on a rotation amount of the input lever.
In this configuration, since there is no need to provide a switch device for turning on the stop lamp in the vicinity of the brake operating element, the brake operating element can be simplified in the vicinity thereof. In the above configuration, the stop lamp can be turned on with high accuracy based on the rotation of the input lever.
In the vehicle brake device, it is preferable that the operation amount detection device sets a return position of the input lever after the brake operation member is turned in a state where the wheel brake is assembled in the vehicle, as an initial position of the input lever. In this configuration, the rotation amount of the brake operating element can be detected with high accuracy.
Effects of the invention
In the vehicle brake device according to the present invention, the operation amount of the brake operation element can be detected based on the rotation amount of the input lever, and therefore the number of parts of the brake device can be reduced.

Detailed Description
Embodiments of the present invention will be described in detail with reference to the accompanying drawings as appropriate.
As shown in fig. 1, the vehicle brake device 1 of the present embodiment (hereinafter, simply referred to as "brake device") can be used for a handlebar type vehicle such as a motorcycle, a three-wheeled motor vehicle, and an All Terrain Vehicle (ATV).
The brake device 1 of the present embodiment constitutes a mechanical brake system for a front wheel side or a rear wheel side of a handlebar type vehicle.
The brake device 1 of the present embodiment includes a brake pedal 10 (a "brake operation tool" in the claims), a mechanical wheel brake 100, an input lever 20, a connection member 30, an operation amount detection device 50, and an electronic control device 200.
As shown in fig. 2, the wheel brake 100 is a drum brake having a drum 110 and a pair of brake shoes 120 and 120 housed in the drum 110. A cylindrical peripheral wall 111 is formed inside the drum 110. Two brake shoes 120, 120 are disposed in the peripheral wall 111.
In the wheel brake 100, the distance between the brake shoes 120, 120 is increased or decreased in accordance with the rotation of the input rod 20 described later. The gap between the brake shoes 120, 120 is increased, and the lining 121 of the brake shoe 120 is pressed against the inner circumferential surface of the circumferential wall 111, thereby generating a braking force at the wheel.
An insertion hole 113 having a circular axial cross section is formed in the rear portion of the outer wall 112 of the drum 110 at the center in the vertical direction, as shown in fig. 3. The insertion hole 113 penetrates the outer wall 112 of the drum 110 as shown in fig. 4.
The operation amount detection device 50 detects the operation amount of the brake pedal 10 (see fig. 1). The operation amount detection device 50 is housed in the drum 110.
The operation amount detection device 50 includes a bearing portion 52 fitted into the insertion hole 113 and a rotation angle sensor 51 housed in the insertion hole 113. Operation amount detection device 50 is a single component in which bearing portion 52 and rotation angle sensor 51 are integrally formed.
The bearing portion 52 is a ball bearing including an outer ring 52a, an inner ring 52b, and a plurality of rolling elements 52c (balls) interposed between the outer ring 52a and the inner ring 52 b.
The outer ring 52a is press-fitted into the insertion hole 113 and fixed to the insertion hole 113. The inner ring 52b is disposed inside the outer ring 52a, and is rotatable with respect to the outer ring 52 a.
As shown in fig. 3, the rotation angle sensor 51 is an annular member and is accommodated in the insertion hole 113. The central axis of rotation angle sensor 51 and the central axis of bearing 52 are arranged on the same axis. The outer diameter of the rotation angle sensor 51 is formed slightly smaller than the inner diameter of the insertion hole 113.
As shown in fig. 4, the rotation angle sensor 51 is a magnetic sensor for detecting a rotation amount of the support shaft 22 of the input lever 20 described later.
The rotation angle sensor 51 detects a change in magnetic field when the magnet rotates with rotation of the inner ring 52 b. Then, in the rotation angle sensor 51, the rotation amount of the inner ring 52b is detected based on the magnetic field change of the magnet.
As shown in fig. 2, the input rod 20 is rotatably coupled to an outer surface of the outer wall 112 of the drum 110.
The input lever 20 includes a lever main body 21 extending in the vertical direction and a support shaft 22 extending from an upper end portion of the lever main body 21 toward the drum 110.
As shown in fig. 3, the support shaft 22 is a shaft member having a circular shaft section. As shown in fig. 4, the support shaft 22 is inserted into the insertion hole 113 of the drum 110. The support shaft 22 is inserted into the rotation angle sensor 51 and press-fitted into the inner race 52b of the bearing 52. Thereby, the support shaft 22 is rotatably supported by the bearing 52.
A rear end of a connection member 30 as a cable or a rod is connected to a lower end of the rod body 21. As shown in fig. 1, the front end of the link member 30 is connected to the brake pedal 10.
When the brake pedal 10 is stepped on, a tensile force acts on the lower end portion of the lever main body 21 toward the front via the connection member 30. Thereby, the input lever 20 rotates relative to the drum 110.
As shown in fig. 4, since the inner ring 52b of the bearing portion 52 rotates together with the support shaft 22, the rotation angle sensor 51 detects the rotation angle of the inner ring 52b to detect the amount of rotation of the input lever 20.
The rotation angle sensor 51 is electrically connected to an electronic control device 200 described later, as shown in fig. 1. The rotation amount of the input lever 20 detected by the rotation angle sensor 51 is output to the electronic control device 200.
The initial position of the input lever 20 is set in the operation amount detection device 50. The initial position of the input lever 20 is the return position of the input lever 20 after the input lever 20 is operated and rotated a plurality of times in a state where the wheel brake 100 is assembled to the handlebar-type vehicle. In this way, the initial position of the input rod 20 is set in a state in which the respective members of the brake device 1 are adapted to each other, and the rotation amount of the input rod 20 can be detected with high accuracy.
In the braking device 1 of the present embodiment as described above, as shown in fig. 1, the rotation angle sensor 51 is housed in the drum 110. In this configuration, the operation amount of the brake pedal 10 can be detected without mounting a rotation angle sensor on the outer surface of the wheel brake 100 in the vicinity of the brake pedal 10. This eliminates the need for a bracket or a cover for the rotation angle sensor, and thus reduces the number of components of the brake device 1.
In the present embodiment, as shown in fig. 4, the operation amount detection device 50 in which the bearing portion 52 and the rotation angle sensor 51 are integrated is housed in the insertion hole 113 of the drum 110, so that the operation amount detection device 50 can be arranged in a compact manner with respect to the wheel brake 100.
In the operation amount detection device 50 of the present embodiment, since the rotation angle sensor 51 is disposed by the insertion hole 113 for inserting the support shaft 22 of the input lever 20, it is not necessary to perform processing for attaching the rotation angle sensor 51 to the drum 110.
Next, the braking control in the braking device 1 of the present embodiment will be explained.
As shown in fig. 1, the brake device 1 of the present embodiment includes an electronic control device 200. The electronic control device 200 is a microcomputer including a cpu (central Processing unit), a rom (read Only memory), a ram (random Access memory), and the like.
The storage unit 210 stores braking force data. The storage unit 210 stores braking force data. The braking force data is data indicating a relationship between the amount of rotation of the input lever 20 and the amount of decrease in the acceleration of the vehicle body.
The amount of decrease in the acceleration of the vehicle body varies depending on the magnitude of the braking force generated by the wheel brake 100. That is, the decrease amount of the acceleration of the vehicle body represents the braking force generated at the wheel brake 100.
The braking force calculation unit 260 estimates the braking force generated by the wheel brake 100 based on the rotation amount of the input lever 20.
When the rotation amount of the input lever 20 is input from the operation amount detection device 50, the braking force calculation unit 260 calculates an estimated value of the braking force corresponding to the rotation amount from the braking force data stored in the storage unit 210.
The estimated value of the braking force calculated by the braking force calculation unit 260 is input to, for example, a control unit of a hydraulic control device of a hydraulic brake system provided for another wheel, and interlocking brake control is executed based on the estimated value of the braking force.
The determination unit 240 obtains a predetermined amount of braking force corresponding to the amount of rotation of the input lever 20 detected by the rotation angle sensor 51 (see fig. 2) of the operation amount detection device 50, from the braking force data. The determination unit 240 receives an input of the amount of decrease in the acceleration of the vehicle body detected by the acceleration sensor AS. The decrease in the acceleration of the vehicle body detected by the acceleration sensor AS indicates the braking force generated by the wheel brake 100.
Next, the determination unit 240 compares a predetermined amount of the braking force in the braking data with the braking force calculated based on the detection result of the acceleration sensor AS.
Then, the determination unit 240 determines the adjustment state of the wheel brake 100 based on whether or not the braking force calculated based on the detection result of the acceleration sensor AS is within a predetermined amount of the braking force in the braking force data.
When the decrease in the acceleration of the vehicle body detected by the acceleration sensor AS is larger than the decrease in the acceleration by the engine brake despite the small amount of rotation of the brake pedal 10, that is, when the braking force generated in the wheel brake 100 is larger than the braking force by the engine brake, the wheel brake 100 may function even in a state where the brake pedal 10 is not operated. In this case, the determination unit 240 determines that the wheel brakes 100 need to be adjusted, and displays the determination result on a display unit such as a lamp or a monitor.
When the decrease in the acceleration of the vehicle body detected by the acceleration sensor AS is smaller than the decrease in the acceleration due to the engine brake despite the large amount of rotation of the brake pedal 10, that is, when the braking force generated in the wheel brake 100 is smaller than the braking force due to the engine brake, there is a possibility that the wear of the lining of the wheel brake 100 is large and the play of the brake pedal 10 is large. In this case, the determination unit 240 determines that the wheel brakes 100 need to be adjusted, and displays the determination result on a display unit such as a lamp or a monitor.
The brake lamp control unit 250 turns on and off the brake lamp BL based on the rotation amount of the input lever 20 detected by the operation amount detection device 50.
In the brake lamp control unit 250, when the brake pedal 10 is depressed, the brake lamp BL is turned on when the amount of rotation of the input lever 20 reaches a predetermined amount. When the brake pedal 10 is returned, the brake lamp BL is turned off when the amount of rotation of the input rod 20 is smaller than a predetermined amount.
In the brake device 1 as described above, the braking force generated in the wheel brake 100 can be detected without providing a tension sensor in the input rod 20 or the connection member 30, and therefore the number of components of the wheel brake 100 can be reduced.
In the brake device 1, the adjustment state of the wheel brakes 100 can be determined based on the rotation amount of the brake pedal 10, and the brake lights BL can be turned on with high accuracy.
Although the brake device 1 according to the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and can be modified as appropriate within a range that does not depart from the gist thereof.
In the operation amount detection device 50 of the present embodiment, as shown in fig. 4, the bearing portion 52 and the rotation angle sensor 51 are integrated, but the rotation angle sensor 51 may be separately housed in the drum 110.
In the present embodiment, the rotational angle of the support shaft 22 is detected using the annular rotational angle sensor 51, but the configuration of the rotational angle sensor is not limited. For example, the rotation angle sensor may be housed in a space inside the drum 110, and the rotation angle of the support shaft 22 may be detected by contact or non-contact.
As in the operation amount detecting device 50A shown in fig. 5, a common rotating member 61 fitted to the outer periphery of the support shaft 22 and a rotation angle sensor 62 attached to the outer periphery of the common rotating member 61 may be provided, and the rotation angle sensor 62 may be disposed between the outer surface of the drum 110 and the input lever 20. In the operation amount detection device 50A, the base portion 62a of the rotation angle sensor 62 is housed in the insertion hole 113. The rotation angle sensor 62 is configured to detect a rotation amount of the common rotating member 61.
In this configuration, by housing a part of the rotation angle sensor 62 in the insertion hole 113, the operation amount detection device 50A can be disposed compactly with respect to the wheel brake 100, and an increase in size of the brake device can be suppressed. Further, by disposing the rotation angle sensor 62 between the outer surface of the drum 110 and the input lever 20, the rotation angle sensor 62 can be protected.
The determination unit of the present invention determines the adjustment state of the wheel brake based on the amount of rotation of the input lever and the braking force generated at the wheel. In the braking device 1 of the present embodiment shown in fig. 1, the braking force generated at the wheels is represented by the amount of decrease in the acceleration of the vehicle body, but the method of representing the braking force generated at the wheels is not limited, and the braking force generated at the wheels may be represented by the amount of decrease in the rotational speed of the wheels, for example.
In the present embodiment, the brake device 1 applied to the brake system having the brake pedal 10 is described, but the brake device of the present invention can be applied to a brake system having a brake lever.
In this case, the determination unit 240 of the electronic control device 200 can determine the adjustment state of the wheel brake 100 based on the rotation amount of the input rod 20 detected by the operation amount detection device 50, and the same operational effects as those of the above-described embodiment can be obtained.
In the above-described embodiment, the case where the brake device of the present invention is applied to a motorcycle is described as an example, but a vehicle to which the brake device of the present invention can be applied is not limited to this, and can be applied to various vehicles.
