Description

Technical Field

[0001] The utility model belongs to the field of brakes, and in particular relates to a travel-adjustable brake. Background Art

[0002] Brake pads are actually brake pad assemblies composed of brake linings and friction pads riveted together. Brake linings are auxiliary accessories used in conjunction with friction pads. When braking, the brake pads are squeezed against the brake disc to generate friction, thereby achieving the purpose of decelerating and braking the vehicle. Due to friction, the brake pads will gradually wear out. To meet the braking needs, the brake pads are designed with friction materials that have sufficient thickness. However, with the use of the car, the friction material will gradually wear and become thinner. When the brake pads are worn to a certain extent, they can still be used, but the braking performance will be greatly reduced, and it is easy to cause safety accidents due to poor braking effect.

[0003] Most of the brakes on the market have the following problems when in use:

[0004] 1. The existing brake relies on the friction between the brake pad and the brake disc to achieve braking during use. However, the distance between the brake pad and the brake disc is fixed and cannot be adjusted during use. After the brake pad is worn out after a period of use, the brake caliper assembly needs a longer travel to make the brake pad contact the brake disc. The braking performance of the brake gradually decreases during the service life of the brake.

[0005] 2. Currently, the contact area between the brake pad and the brake disc is fixed, and the braking effect of the brake is constant, which cannot adapt to the braking needs of operators with different vehicles or driving habits. Summary of the invention

The first brake pad 9 and the second brake pad 10 are symmetrically distributed about the brake disc 1. When the brake is used, the first screw rod 5 or the second screw rod 6 is driven to rotate by a plurality of groups of motors respectively, and the position of the mounting seat 2 on the frame and the position of the adjusting frame 4 on the mounting frame 3 are adjusted accordingly under the limiting action of the frame or the mounting frame 3, thereby realizing the adjustment of the stroke between the first brake pad 9 and the second brake pad 10 and the brake disc 1, and the usage habits of different vehicles and drivers.

[0032] Multiple groups of first brake pads 9 are rotatably connected to the mounting disk 8 through the mounting shaft 25, a mounting ring 27 is provided in the mounting disk 8, and the mounting ring 27 is rotatably connected to the mounting disk 8 through a bearing, a gear 26 is sleeved on the mounting shaft 25, an inner tooth 28 is provided in the mounting ring 27, and an outer tooth 29 is provided outside the mounting ring 27, and the mounting ring 27 is meshed with the gear 26 through the inner tooth 28, a driving wheel 30 is provided in the mounting disk 8, and the driving wheel 30 is rotatably connected to the mounting disk 8 through a rotating shaft, and the driving wheel 30 is meshed with the mounting ring 27 through the outer tooth 29, and the driving wheel 30 is driven to rotate by a motor, and the mounting ring 27 is rotated in conjunction with the outer tooth 29, and the gear 26 drives the mounting shaft 25 and multiple groups of brake pads to rotate synchronously in conjunction with the inner tooth 28, thereby adjusting the total area that the first brake pad 9 can contact with the brake disk 1, and the contact area between the brake disk 1 and the brake pad is centered on the specific strength of the brake.

[0033] A mounting tube 11 is provided on the mounting seat 2, and a push plug 12 is provided in the mounting tube 11. The push plug 12 is slidably connected to the mounting tube 11. An oil inlet 13 and an oil outlet 14 are provided on the mounting tube 11. The oil inlet 13 and the oil outlet 14 are distributed on both sides of the rear end of the push plug 12. The push plug 12 is arranged corresponding to the mounting disk 8. Two groups of symmetrically distributed first branch pipes 17 are provided on the mounting tube 11.

[0034] The first piston rod 15 is slidably connected with the first bracket 16 and the first branch pipe 17. The first piston rod 15 is sleeved with a first spring 18. The two ends of the first spring 18 are fixedly connected to the first piston rod 15 and the first bracket 16 respectively. When the push plug 12 pushes the first brake pad 9 to contact the brake disc 1 to gradually reduce the speed of the car, if the push plug 12 is pushed to the limit and the vehicle is still not completely stopped, the hydraulic oil in the mounting pipe 11 continues to flow through the oil inlet 13 and the oil outlet 14 until the hydraulic oil cannot go out from the oil outlet 14. The pressure of the hydraulic oil filled in the mounting pipe 11 continues to increase until the first piston rod 15 is pushed open and the first spring 18 is compressed, so that the hydraulic oil enters the first branch pipe 17.

[0036] The second piston rod 21 is slidably connected to the second bracket 20, and a second spring 22 is sleeved on the second piston rod 21. Both ends of the second spring 22 are fixedly connected to the second piston rod 21 and the second bracket 20 respectively. The hydraulic oil continuously enters the second branch pipe 19 to push the second piston rod 21 and stretch the second spring 22. During the sliding process of the second piston rod 21, the mounting frame 3 and the adjusting frame 4 fixedly connected thereto are pushed to move toward the brake disc 1 until the second brake pad 10 contacts the brake disc 1 to complete the braking.

[0037] The working principle of the stroke-adjustable brake is as follows: when the brake is used, multiple groups of motors are used to drive the first screw rod 5 or the second screw rod 6 to rotate respectively. Under the limiting action of the frame or the mounting frame 3, the position of the mounting seat 2 on the frame and the position of the adjusting frame 4 on the mounting frame 3 are adjusted accordingly, thereby realizing the adjustment of the stroke between the first brake pad 9 and the second brake pad 10 and the brake disc 1. According to the usage habits of different vehicles and drivers, the motor drives the driving wheel 30 to rotate, and the mounting ring 27 rotates in conjunction with the external teeth 29, and the gear 26 drives the mounting shaft 25 and multiple groups of brake pads to rotate synchronously in conjunction with the internal teeth 28, thereby adjusting the total area that the first brake pad 9 can contact with the brake disc 1. The contact area between the brake disc 1 and the brake pad is located at the specific strength of the brake. It is connected to the hydraulic system through the oil inlet 13 and the oil outlet 14. The entry of hydraulic oil pushes the push plug 12 forward until the push plug 12 contacts the mounting disc 8, thereby applying the first brake. The plate 9 is gradually pushed to the brake to complete the initial braking. When the push plug 12 pushes the first brake pad 9 to contact the brake disc 1, so that the speed of the car is gradually reduced, if the push plug 12 is pushed to the limit and the vehicle is still not completely stopped, the hydraulic oil in the mounting tube 11 continues to flow through the oil inlet 13 and the oil outlet 14 until the hydraulic oil cannot go out from the oil outlet 14, and the hydraulic oil pressure filled in the mounting tube 11 continues to increase until the first piston rod 15 is pushed open to compress the first spring 18, so that the hydraulic oil enters the first branch pipe 17, and the hydraulic oil continues to enter the first branch pipe 17 to continuously push the first piston rod 15 until the oil inlet 13 of the second branch pipe 19 is exposed, and the hydraulic oil enters the second branch pipe 19, and the hydraulic oil continues to enter the second branch pipe 19 to push the second piston rod 21, stretching the second spring 22, and during the sliding process of the second piston rod 21, it pushes the mounting frame 3 and the adjusting frame 4 fixedly connected thereto to move toward the brake disc 1 until the second brake pad 10 contacts the brake disc 1, completing the braking.
