Abstract
The invention relates to a spline gear-driven brake caliper for a disc brake. For the drive modes of the brake caliper for the disc brake, a hydraulic mode using a piston and a cylinder and a pneumatic mode using pressure in an air chamber and the lever principle are widely applied, and an electronic mode using the rotation of a motor to drive a planetary gear and a ball screw so as to complete action is also provided. The invention initiates a brand-new drive mode of the brake caliper and provides a driving mechanism which is safer and has larger transmission moment than other technology by using the sliding action of the spline gears and can change slight rotary motion into simultaneous left and right linear motion. The slight rotary motion in a certain direction is changed into the simultaneous left and right linear motion by combining a plurality of spline gears and using the sliding action thereof; and in addition, the spline gears can transmit considerable moment due to high strength, so that the requirement of the brake caliper for the disc brake on high compressive force is met.
Description
Affiliated technical field
The present invention relates to the novel driving structure of a kind of disk type braker with brake calipers.
Background technique
The driving overwhelming majority of disk type braker in the past all adopts the mode of oil pressure, comes execution by piston and cylinder.Other has the fraction disk type braker then to adopt air pressure mode or electronics mode, and the air pressure mode has been utilized the principle of lever, and the electronics mode is come execution by planetary pinion and ball screw.
Summary of the invention
The technical problem to be solved in the present invention: technology in the past all respectively has pluses and minuses.Oil pressure mode braking force is big, and in light weight, so the disk type braker of car all adopts this mode.But, fricative heat can cause the deterioration or the hydraulic pressure of oil low, and the leakage of oil also may be accidents caused, so lack Security.The air pressure mode is subjected to the influence of frictional heat few, even air leak to a certain degree takes place, and also can supply.If have the function of Parking Brake simultaneously concurrently, even pressurized air can not get supply fully, Security still can be guaranteed under the effect of spring strength.Yet present pneumatic-typed disk type braker is equipped with automatic adjustment arm (carrying out the mechanism that the gap is adjusted automatically with respect to the wearing and tearing of friction material), and number of components is many, weight and volume is big, installation needs the space, and cost is also very high.Except hydraulic type and pneumatic-typed, utilize the rotation drive planetary pinion of motor and the electronic type that ball screw is come execution in addition.Electronic type, is generally not too used so only be used for special equipment because cost is very high.Compare with hydraulic type, pneumatic-typed will have more Security comparatively speaking, and the objective of the invention is to provide a kind of new driving mechanism to air-pressure disc brake, adopts the disk type braker braking effect of this invention good, is fit to large vehicle and uses.Specifically, the present invention is the change to the brake calipers driving mode, is a kind of brand-new mode of having utilized the slip effect of spline gear, provides a kind of than the safer stronger driving mechanism of other technology.In addition, the present invention has reduced number of components to the utmost, thereby reaches the purpose that reduces cost.
The technical solution used in the present invention:, need a kind of slight rotatablely moving being converted to left simultaneously and straight-line mechanism to the right for solving above-mentioned technical problem.A plurality of spline gears are combined, and under the slip effect of spline gear, slight the rotatablely moving of certain orientation just can be transformed into left and straight line motion to the right simultaneously.And employed spline gear has sizable intensity, can conduct very big power moment.Just in time the suit the requirements requirement of brake calipers of disk type braker of very big compressive force of this point.
Beneficial effect of the present invention: by the present invention, slight rotatablely moving ideally can be converted to left simultaneously and straight line motion to the right, not only have Security but also can bring into play good effect, be suitable for this vehicle important safety of break parts most.In addition,,, just can produce very big driving moment, use thereby be suitable for large vehicle by spline gear good slip effect and the enough intensity of gear if the moment of rotation of giving is big.Also have, reduced the quantity of parts dramatically,, popularize socially and be easier to so reduced cost widely, also just big more to the contribution of society.

Meet explanation among the figure: 1. piston, 2. in wheel, 3. foreign steamer, 4. running shaft is 5. adjusted arm, 6. air chamber, 7. air chamber support, 8. dust-proof cover A, 9. dust-proof cover B, 10. brake calipers, 11. brake-caliper supports, 12. friction disks, 13. outside brake pads, 14. inboard brake pads
Embodiment
The specific embodiment of the present invention is shown in Fig. 1～3.
Fig. 1 is that the present invention is used in large truck. the oblique drawing of the air-pressure disc brake during passenger vehicle, Fig. 2 are the sectional views of the A-A of Fig. 1.At first under the thrust of 6 air chambers, 5 adjust arm automatically rotates, and this rotation is conducted to slight rotating force of 4 running shafts.The front end of running shaft is processed to spline gear, the internal diameter of wheel also is the spline gear shape in 2, the slip effect of the spline gear by internal diameter, wheel rotate and advances in 2 on one side, and 2 interior motive forces of taking turns the generation of advancing conduct to 14 inboard brake pads by 1 piston.
In addition, the external diameter of 2 interior wheels also is processed into the spline gear shape, and under the rotation of wheel drove in 2,3 foreign steamers also will rotate together.3 foreign steamers are pressed in 10 brake caliperss and can't rotate, so take turns 2 under the slip effect that produces between the spline gear of the spline gear of external diameter and 3 foreign steamer internal diameters, 3 foreign steamers are drawn back.Because 3 and 10 brake caliperss are one,, and then strength is conducted to the outside 13 brake pads so brake calipers is also drawn back.
Under the effect of the compressive force of 14 inboard brake pads and 13 outside brake pads, 12 friction disks that rotate with wheel produce braking force.Utilize the slip effect of spline gear, making rotatablely moves convert to simultaneously left and straight-line mechanism to the right specifically as shown in Figure 3.Make by 7 air chamber supports and can only do 4 of spinning movement and rotate, because wheel is unfixed in 2, so while under the effect of spline gear, rotate and advance.Meanwhile, under the effect of the spline gear on 2 the external diameter, 3 foreign steamers also will be followed rotation together.But, owing to 3 foreign steamers are pressed in stuck-at-0 brake calipers and can't rotate, so under the slip effect of spline gear, 3 can only draw back.And 10 brake caliperss are confined on sense of rotation.
Also do not use break concrete instance of the present invention at present.But,, thereby can convert to simultaneously left rotatablely moving and straight line motion to the right, so all have utilization to be worth in various fields because the present invention has utilized the slip effect of spline gear.Can applicable field be exactly large truck immediately now. the passenger vehicle disk type braker.The large truck of selling on the present market. the price of the disk type braker that passenger vehicle is used approximately is 2～3 times of existing drum brake, and only is used on the special car, and reaching universal degree also needs considerable time., the number of components of having used disk type braker of the present invention reduces, and cost decreases, and price is basic identical with drum brake.The present invention is one and utilizes very high, very big to the contribution to society invention of possibility on the whole.
