Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to an electro-hydraulic integrated brake pedal and a vehicle. Background Art

[0002] Large electric wheel dump trucks are important means of transportation in large open-pit mines and water conservancy projects. The road conditions on which they travel are extremely harsh and complex, which requires the vehicle's braking system to ensure safety, reliability and comfortable operation under various working conditions.

[0003] At present, for ordinary hydraulic braking methods, due to the excessive weight of the vehicle when fully loaded, the vehicle needs a large braking force when it is driving at high speed until it stops, which places high demands on the material of the friction plate. In addition, the friction plate needs to be replaced frequently due to the frequent use of hydraulic brakes, which is also very expensive. Therefore, electric wheel dump trucks usually use a braking method that combines electric retarding braking and hydraulic braking. When the vehicle speed is higher than the preset value, electric retarding braking is used. When the vehicle speed is lower than the preset value, hydraulic braking is used to stop the vehicle. This can extend the service life of the brakes, and at the same time, it can also achieve energy recovery for current new energy vehicles.

[0004] However, the current mainstream brake pedal structure adopts the form of two independent electric and hydraulic pedals. When operating the brakes, you need to first step on the electric retarding brake pedal, and then switch to step on the other hydraulic brake pedal to brake after braking to a certain speed. The operation is relatively complicated and it is easy to make operational errors in an emergency, leading to unnecessary accidents.

[0005] Therefore, there is an urgent need for an electro-hydraulic integrated brake pedal to solve the above problems. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] like Figure 1As shown, the present embodiment provides an electro-hydraulic integrated brake pedal, which includes a support seat 1, a hydraulic brake assembly and an electric retarding brake assembly, wherein the hydraulic brake assembly includes a hydraulic brake plate 21 and a valve body 22, wherein the hydraulic brake plate 21 is pivoted with the support seat 1 by a first pivot axis 23, the first pivot axis 23 extends in a first direction, and the hydraulic brake plate 21 swings to drive the valve core 221 to extend and retract along a second direction Y; the electric retarding brake assembly includes an electric brake plate 31, a reset member and a detector, wherein the electric brake plate 31 is pivoted with the hydraulic brake plate 21 or the support seat 1 by a second pivot axis 33, the second pivot axis 33 extends in the first direction, the electric brake plate 31 is not subjected to external force, the reset member is configured to make the electric brake plate 31 and the hydraulic brake plate 21 be arranged at an angle, drive the electric brake plate 31 to swing, so that the electric brake plate 31 abuts against the hydraulic brake plate 21 and drives the hydraulic brake plate 21 to swing, and the detector is used to detect the swing angle of the electric brake plate 31. Specifically, the first direction and the second direction Y are perpendicular.

[0038] When the vehicle needs to decelerate slowly, if the vehicle speed is greater than the preset value a, the driver only needs to drive the electric brake plate 31 to move relative to the hydraulic brake plate 21, and the position of the hydraulic brake plate 21 remains unchanged, and then the vehicle is slowed down by electric retarding braking without starting the hydraulic brake system.

[0039] When the vehicle needs to stop slowly, if the speed of the vehicle is greater than the preset speed a, the driver drives the electric brake plate 31 to swing relative to the hydraulic brake plate 21. The detector is used to detect the swing angle α1 of the electric brake plate 31. The motor determines the braking force output on the wheel through the swing angle α1 of the electric brake plate 31, thereby realizing the slow braking of the vehicle. When the vehicle speed drops below a, the driver continues to drive the electric brake plate 31, so that the electric brake plate 31 abuts against the hydraulic brake plate 21 and drives the hydraulic brake plate 21 to swing at an angle α2, thereby causing the valve core 221 to move relative to the cylinder body 222 along the second direction Y. In this process, the hydraulic brake system outputs a corresponding value of hydraulic braking force to the brake disc of the wheel according to the movement of the valve core 221 until the vehicle stops. The electro-hydraulic integrated brake pedal can realize the sequential control of electric slow braking and hydraulic braking on one pedal at the same time, reducing the labor intensity of the operator; when the brake pedal is stepped on, electric slow braking is performed first, which greatly prolongs the service life of the hydraulic brake and the brake disc;

[0040] Optionally, the value of a is 5Km / h-20Km / h, preferably, the value of a is 5Km / h.

[0041] When the vehicle needs to be braked urgently, the driver drives the electric brake plate 31 to swing greatly, so that the electric brake plate 31 abuts against the hydraulic brake plate 21 and drives the hydraulic brake plate 21 to swing. At this time, the detector detects the swing angle of the electric brake plate 31 and starts the electric retarding brake. After the valve core 221 of the valve body 22 moves, the hydraulic brake is started, and the vehicle can be braked urgently.

[0042] Specifically, electric retarding brake and hydraulic brake are both existing technologies and will not be described in detail here.

[0043] Optionally, the support seat 1 is provided with a through hole along the second direction Y, the cylinder body 222 of the valve core 221 is fixed on one side of the support seat 1, and the valve core 221 passes through the through hole; one end of the hydraulic brake plate 21 is pivoted to the other side of the support seat 1 through the first pivot shaft 23, and the middle part of the hydraulic brake plate 21 drives the valve core 221 to move. In this embodiment, the support seat 1 specifically includes a base plate 11 and two pivot ears 12 arranged on the base plate 11 at intervals along a first direction. A through hole is provided on the base plate 11. The cylinder body 222 is fixedly arranged on one side of the base plate 11. The valve core 221 passes through the through hole and extends to the other side of the base plate 11. One end of the hydraulic brake plate 21 is arranged between the two pivot ears 12. The first pivot axis 23 is simultaneously passed through the two pivot ears 12 and one end of the hydraulic brake plate 21. The middle part of the hydraulic brake plate 21 is clamped with the valve core 221 on the side opposite to the base plate 11. When the hydraulic brake plate 21 swings toward the direction close to the base plate 11, the valve core 221 can be driven to extend into the cylinder body 222.

[0044] Optionally, the electric brake plate 31 may be pivotally connected to the two pivot ears 12 via the second pivot axis 33 , and may also be pivotally connected to the hydraulic brake plate 21 via the second pivot axis 33 .

[0045] Optionally, a through hole is provided in the middle of the hydraulic brake plate 21 at a position opposite to the valve core 221, and the valve core 221 is inserted into the through hole; the hydraulic brake assembly also includes an adjusting nut 24 and an elastic member 25, the adjusting nut 24 is sleeved on the valve core 221 and is threadedly connected to the valve core 221, the adjusting nut 24 is provided between the support seat 1 and the hydraulic brake plate 21, the outer diameter of the adjusting nut 24 is larger than the outer diameter of the through hole, one end of the elastic member 25 is fixedly connected to the support seat 1, and the other end is fixedly connected to the hydraulic brake plate 21. In this embodiment, the portion of the valve core 221 away from the cylinder body 222 is provided with an external thread, and the adjusting nut 24 is sleeved on the valve core 221 and is threadedly connected with the external thread on the valve core 221. Since the adjusting nut 24 is provided between the support seat 1 and the hydraulic brake plate 21, and the outer diameter of the adjusting nut 24 is larger than the outer diameter of the perforation, the position of the adjusting nut 24 relative to the valve core 221 can be adjusted, and the angle of the hydraulic brake plate 21 relative to the bottom plate 11 can be adjusted to achieve the adjustment of the braking stroke of the hydraulic brake plate 21. The role of the elastic member 25 is, on the one hand, to make the hydraulic brake plate 21 always abut against the adjusting nut 24; on the other hand, to provide a reset force for the reset of the hydraulic brake plate 21. Specifically, the elastic member 25 can be a coil spring or elastic rubber, etc.

[0046] Optionally, the hydraulic brake assembly further includes a guide pin 26 and a guide sleeve 27, one of which is fixed to the support seat 1 and the other is pivotally connected to the hydraulic brake plate 21, the guide pin 26 is inserted into the guide sleeve 27 and slides with the guide sleeve 27; the elastic member 25 is a helical compression spring, and the guide pin 26 and the guide sleeve 27 are both inserted into the helical compression spring. In this embodiment, the guide pin 26 and the guide sleeve 27 are both inserted into the helical compression spring, which can limit the helical compression spring, so that the elastic force of the helical spring is consistent with the sliding direction of the guide pin 26 and the guide sleeve 27.

[0047] Optionally, the reset member includes a swing rod 321, a guide wheel 322 and a torsion spring, one end of the swing rod 321 is pivoted to the electric brake plate 31 by a third pivot axis, the third pivot axis extends along the first direction, and the other end is rotatably connected to the guide wheel 322. The torsion spring is configured to make the other end of the swing rod 321 approach the hydraulic brake plate 21 so that the guide wheel 322 abuts against the hydraulic brake plate 21. In this embodiment, the torsion spring is sleeved on the third pivot axis, one acting end of the torsion spring is fixedly connected to the electric brake plate 31, and the other acting end is fixedly connected to the swing rod 321. When the electric brake plate 31 is not subjected to the driving force of the driver, the torsion spring drives the swing rod 321 to swing in the direction close to the hydraulic brake plate 21, and then reacts the electric brake plate 31 to move in the direction away from the hydraulic brake plate 21, so that when the electric brake plate 31 is not subjected to the driving force of the driver, the electric brake plate 31 and the hydraulic brake plate 21 form a preset angle. When the driver acts on the electric brake plate 31 with driving force, since the force driving the valve core 221 to move is greater than the maximum torsion of the torsion spring, at this time, the hydraulic brake plate 21 does not swing, and the electric brake plate 31 swings in the direction close to the hydraulic brake plate 21, the other end of the swing rod 321 is relatively displaced with the hydraulic brake plate 21, and the torsion spring is elastically deformed. When the driver removes the force applied to the electric brake plate 31, the torsion force of the torsion spring acts on the swing rod 321, thereby causing the swing rod 321 to move relative to the hydraulic brake plate 21, so that the electric brake plate 31 and the hydraulic brake plate 21 are reset to a preset angle. Preferably, a guide wheel 322 is provided at the other end of the swing rod 321, and the guide wheel 322 abuts against the hydraulic brake plate 21, thereby causing rolling friction between the swing rod 321 and the hydraulic brake plate 21, thereby reducing the force required by the driver to drive the electric brake plate 31 to move relative to the hydraulic brake plate 21.

[0048] Optionally, the detector is used to detect the angle change of the swing rod 321. In this embodiment, the detector is an angle sensor, and the angle sensor detects the angle change of the swing rod 321. In other embodiments, the angle sensor can also detect the angle change of the electric brake plate 31.

[0049] Optionally, the reset member is arranged on the electric brake plate 31 on one side of the second pivot shaft 33, and the electric brake plate 31 on the other side of the second pivot shaft 33 is provided with an abutting portion 311, and the abutting portion 311 is arranged spaced apart from the support seat 1 along the second direction Y; the electric retarding brake assembly further comprises a limiter 34, the limiter 34 is arranged on the support seat 1 and is located between the abutting portion 311 and the support seat 1, and the abutting portion 311 can abut against the limiter 34. In this embodiment, when the abutting portion 311 abuts against the limiter 34, it is exactly the preset angle between the electric brake plate 31 and the hydraulic brake plate 21.

[0050] Optionally, the stopper 34 is a bolt, the bolt is threadedly connected to the support seat 1, and the axis of the bolt is arranged along the second direction Y. In this embodiment, by screwing the bolt, the distance of the bolt relative to the bottom plate 11 along the second direction Y can be adjusted, and finally the preset angle between the electric brake plate 31 and the hydraulic brake plate 21 is adjusted, thereby adjusting the preset stroke of the electric brake plate 31.

[0051] The electro-hydraulic integrated brake pedal also includes a foot pedal 4, which is detachably arranged on the side of the electric brake plate 31 away from the hydraulic brake plate 21. In this embodiment, the driver's foot directly acts on the foot pedal 4, and the purpose of driving the electric brake plate 31 is achieved by driving the foot pedal 4. Therefore, the installation position and installation angle of the foot pedal 4 directly affect the driver's use experience. Therefore, the present application makes the foot pedal 4 detachable and arranged on the electric brake plate 31, and then different foot pedals 4 can be replaced according to the changes in the electro-hydraulic integrated brake pedal installed on different vehicles and the changes in the operating habits of different drivers. In this way, the driving comfort of the driver is improved.

[0052] This embodiment also provides a vehicle, including the electro-hydraulic integrated brake pedal in the above solution.

[0053] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
