Description

Technical Field

[0001] The invention relates to the technical field of anti-lock braking of electric vehicles, and in particular to an ABS system for vehicles. Background Art

[0002] The popularity of vehicles has brought a lot of convenience to people's lives, especially shortening the time required for a unit trip. In order to facilitate parking, various vehicles in daily life have braking systems. Among them, cars all have anti-lock braking systems, referred to as ABS. The function is to automatically control the braking force of the brakes when the car brakes, so that the wheels are not locked and are in a rolling and sliding state to ensure that the adhesion between the wheels and the ground is at the maximum value.

[0003] However, in the field of electric vehicles, especially the brake devices for two-wheeled electric vehicles, whether hydraulic disc brakes or drum brakes, can only lock the wheels when braking, and wheel locking can easily reduce the friction between the tires and the ground, causing the tires to lose grip, thereby causing uncontrollable dangerous situations such as vehicle skidding and tail swinging. That is, most electric vehicles currently do not have an anti-lock braking system, which will cause the brakes to lock when the electric vehicle is riding, causing serious accidents such as tire skidding and tire slipping, especially on rainy days, slippery roads and other low-adhesion roads. The probability of this happening is higher, causing the electric vehicle to lose control and cause dangerous accidents.

[0004] The principle of some existing brakes suitable for electric vehicles is to control the oil pressure to adjust the tightness of the brake pads. This device is integrated with the brake, which is not only costly and difficult to install, but also difficult to repair once the oil pump is damaged, and even has a direct impact on the normal use of the brake.

DETAILED DESCRIPTION

[0037] The present invention is further described in detail below with reference to the drawings and embodiments.

[0038] like Figure 1 As shown, a vehicle ABS system includes a brake disc 1 installed on one side of a wheel hub 10, wherein the brake disc 1 is provided with a brake part 2 and an adjusting rod driving part 3, wherein the brake part 2 is provided with a matching brake mechanism 4, and the adjusting rod driving part 3 is provided with a matching adjusting rod driving mechanism 5; the adjusting rod driving part 3 rotates to drive the adjusting rod driving mechanism 5 to adjust the tightness of the brake mechanism 4; and the brake mechanism 4 is connected to the handbrake through a brake line 9.

[0040] The brake mechanism 4 further includes a brake pad driving module (not marked in the figure) that can drive the first brake pad 43 to move, and the brake pad driving module is installed in the movable cavity 46 of the caliper housing 41; the brake pad driving module can penetrate the caliper housing 41 and be connected to an external brake line connecting rod 47, and the brake line connecting rod 47 is connected to the brake line 9. The other end of the brake line 9 is connected to the hand brake.

[0041] This embodiment provides two structural forms of the drive module under the same drive principle:

[0042] The first structural form

[0043] like Fig.13 and 14 As shown, the brake pad driving module includes a first driving block 48 and a second driving block 49 whose end faces match each other. A rotating shaft 410 is provided at the other end of the first driving block 48, and the rotating shaft 410 can pass through a through hole 411 provided in the caliper housing 41; the first driving block 48 can drive the second driving block 49 to perform telescopic movement by rotating, so as to adjust the distance between the first brake pad 43 and the second brake pad 44.

[0044] Specifically, a first C-shaped slope 412 and a second C-shaped slope 413 connected end to end are arranged on the first end surface of the first driving block 48; correspondingly, a third C-shaped slope 414 and a fourth C-shaped slope 415 connected end to end are arranged on the first end surface of the second driving block 49, the first C-shaped slope 412 and the third C-shaped slope 414 have the same specifications and can be completely fitted, and the second C-shaped slope 413 and the fourth C-shaped slope 415 have the same specifications and can be completely fitted; the second end surface of the second driving block 49 can be connected to the first brake pad 43; the first end surface of the first driving block 48 The rotating shaft 410 is vertically connected to the two end faces, and the rotating shaft 410 can pass through the through hole 411 and be connected to the external brake line connecting rod 47. The brake line connecting rod 47 can drive the rotating shaft 410 to rotate clockwise or counterclockwise under the pulling of the brake line 9, and at the same time drive the first end face of the first driving block 48 and the first end face of the second driving block 49 to lift (extend) or descend (contract) and slide (the C-shaped slopes slide with each other, the contact surface between the C-shaped slopes becomes smaller when lifting or extending; the contact surface between the C-shaped slopes becomes larger when descending or contracting).

[0045] In order to facilitate the smooth rotation of the rotating shaft 410 in the through hole 411 , a bearing sleeve 416 is further sleeved on the rotating shaft 410 , and the outer wall of the bearing sleeve 416 is connected to the inner wall of the through hole 411 .

[0046] The second structural form

[0047] like Fig.12 As shown, the brake pad driving module includes a threaded rotating shaft 420 with a threaded wall 419 at one end, and a threaded driving block 422 with a threaded groove 421, the threaded groove 421 matches the threaded wall 419, and the other end of the threaded rotating shaft 420 can pass through the caliper housing 41 (that is, through the through hole 411); the other end of the threaded driving block 422 is connected to the first brake pad 43.

[0048] The structure for connecting the rotating shaft 410 or the threaded rotating shaft 420 with the brake line connecting rod 47 in this embodiment is specifically as follows: an annular groove 417 is opened along the end of the rotating shaft 410 or the threaded rotating shaft 420, and the annular groove 417 is connected to one end of the brake line connecting rod 47, and the other end of the brake line connecting rod 47 is connected to the brake line 9.

[0049] like Fig.11 and 15As shown, as a further optimization of this embodiment, it also includes a torsion spring 418 that can be sleeved on the rotating shaft 410 or the threaded rotating shaft 420, the bottom hook of the torsion spring 418 is hooked with the caliper housing 41, and the top hook of the torsion spring 418 is hooked with the side of the brake line connecting rod 47; this structure can ensure that the brake line connecting rod 47 can automatically return to its original position each time it swings, that is, after the brake is released, it can ensure that the brake pad returns to its original position without continuing to lock the brake disc.

[0050] like Fig.15 As shown, as a structural form for automatic return of the first brake pad 43, a group of mutually symmetrical guide rods 423 are provided in the clamping portion 42, and correspondingly, guide grooves 45 matching the guide rods 423 are respectively opened on the first brake pad 43 and the second brake pad 44, and the guide rods 423 respectively penetrate the guide grooves 45; a spring (not marked in the figure) is also sleeved on the guide rod 423 corresponding to the first brake pad 43 and the second brake pad 44, so that when the brake is released, the first brake pad 43 can automatically return to its position under the reaction force of the spring.

[0051] like Figure 2-5 As shown, as an optimization of the adjusting rod driving mechanism 5 described in this embodiment, the adjusting rod driving mechanism 5 includes an adjusting rod 51, the upper section of the adjusting rod 51 matches the brake line connecting rod 47, and the lower section of the adjusting rod 51 matches the adjusting rod driving part 3; the middle section of the adjusting rod 51 is provided with a first hinge block 52, and correspondingly, a vertical second hinge block 53 is provided on the caliper adapter code 6, and the first hinge block 52 and the second hinge block 53 are hinged through a pin shaft 54.

[0052] As an optimization of the upper section of the adjusting rod 51 acting on the brake line connecting rod 47 in this embodiment, a ring 55 is provided at the top end of the adjusting rod 51, and a short shaft 56 that can act on the brake line connecting rod 47 is sleeved in the ring 55.

[0053] In addition, the upper section of the adjusting rod 51 is sleeved with a tension spring 57, the upper section of the adjusting rod 51 is hooked with a hook of the tension spring 57, and the other hook of the tension spring 57 is hooked with the fork 7 or the wheel hub 10 or the wheel hub shaft 36. In this embodiment, the tension spring mainly ensures that the lower section (or bottom end) of the adjusting rod 51 is always in contact with the adjusting rod driving part 3, and is driven to make corresponding movements under the rotation of the adjusting rod driving part 3.

[0054] like Figure 5As shown, as an optimization of the brake disc 1 in this embodiment, a shaft through hole 35 is provided on the brake disc 1 for the hub shaft 36 to pass through, and the shaft through hole 35 is cocentric with the brake disc 1; the brake disc 1 is provided with an annular brake portion 2 for the brake pad to act on, and the adjusting rod driving portion 3 is provided along the inner circle of the brake portion 2, and the adjusting rod driving portion 3 rotates synchronously with the brake disc 1 (the brake disc is fixed by the hub shaft 36 or the wheel hub 10).

[0055] As an optimization of the adjusting rod driving unit 3 in this embodiment, the adjusting rod driving unit 3 includes two structural forms:

[0056] The first one, such as Figure 6 As shown, the adjusting rod driving part 3 is an annular boss 31 arranged on the outer side surface of the brake disc 1, and the inner wall of the annular boss 31 is provided with a plurality of arc-shaped flanges 32, and the annular boss 31 and the brake disc 1 are cocentric; the inner walls of the annular boss 31 and the arc-shaped flanges 32 can conflict with the lower section of the adjusting rod 51; in this embodiment, the distances between adjacent arc-shaped flanges 32 are the same.

[0057] Specifically, the annular boss 31 can limit the end of the vertically arranged adjusting rod 51. When the annular boss 31 rotates until the arc-shaped flange 32 collides with the end of the adjusting rod 51, the adjusting rod 51 will be given an angle to swing. While swinging, the top of the adjusting rod 51 directly pushes the brake line connecting rod 47 to loosen the brake line 9; then as the rotation continues, the end of the adjusting rod 51 will continue to fit the inner wall of the annular boss 31. At this time, the adjusting rod 51 will be given an angle to swing. While swinging, the force of the top of the adjusting rod 51 pushing the brake line connecting rod 47 disappears, and the brake line 9 continues to tighten under the force of the handbrake not released. Such a cycle can realize the anti-lock function of the brake disc 1.

[0058] The second type, such as Figure 7 As shown, the adjusting rod driving part 3 is an annular track groove 33 arranged on the side of the brake disc 1, and a plurality of arc grooves 34 are arranged on the annular track groove 33. The annular track groove 33 is cocentric with the brake disc 1, and the arc groove 34 is connected with the annular track groove 33. The lower section of the adjusting rod 51 is limited by the annular track groove 33 or the arc groove 34. In this embodiment, the distances between adjacent arc grooves 34 are the same.

[0059] Specifically, the annular track groove 33 can limit the end of the vertically arranged adjusting rod 51. When the annular track groove 33 rotates to the arc groove 34 to change the end path of the adjusting rod 51, the adjusting rod 51 will be given an angle swing. While swinging, the top of the adjusting rod 51 directly pushes the brake line connecting rod 47 to loosen the brake line 9; then as the rotation continues, the end of the adjusting rod 51 will continue to fit the inner wall of the annular track groove 33. At this time, the adjusting rod 51 will be given an angle swing. While swinging, the force of the top of the adjusting rod 51 pushing the brake line connecting rod 47 disappears, and the brake line 9 continues to tighten under the force of the handbrake not released. Such a cycle can realize the anti-lock function of the brake disc 1.

[0060] like Figure 5-7 As shown, as a further optimization of the brake disc 1 in this embodiment, a plurality of heat dissipation holes 37 are opened in the brake part 2. The heat dissipation principle of the heat dissipation holes 37 is to reduce the clamping friction area between the brake pad and the brake disc 1; in addition, it can also be beneficial to the discharge of foreign matter attached to the brake disc 1, that is, the attachment area is small, and the foreign matter can fall along the heat dissipation holes, which also helps to reduce the weight.

[0061] In this embodiment, a plurality of assembly grooves 38 for fixing with the wheel hub 10 are provided between the adjusting rod driving portion 3 and the rotating shaft through hole 35 , and the wheel hub 10 is provided with a tire 11 .

[0062] In this embodiment, the brake disc 1 and the adjusting rod driving part 3 are integrally formed, and the brake disc 1 is made of corrosion-resistant metal.

[0063] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be thought of by anyone familiar with the technology within the technical scope disclosed by the present invention are all within the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the scope of the claims.
