Description
Technical field
The utility model relates to automotive field, specifically a kind of automobile brake pedal arm.
Background technology
Along with the development of science and technology and the raising of people's living standard, what automobile had progressively become people's trip must have the vehicle, has more paid close attention to the consideration to traveling comfort, fuel economy and safety when purchasing car.
Automobile brake pedal arm structure is critical component in auto pedal system, is widely used in manned vehicle and Light-duty Vehicle field is referred to as brake pedal apparatus.Brake pedal arm configuration is crossed axis of revolution and is connected with the hole on support.Its effect utilizes the rotation of pedal arm structure again on pedal support, the vacuum of vacuum pump is converted into power, obtains higher brake fluid pressure, alleviate the working strength of chaufeur, raising vehicle operating traveling comfort.Due to the minimizing of pedal arm structural weight, alleviate the weight of entire vehicle, improve fuel economy.
Brake pedal arm configuration handles vacuum booster work, and when braking, gently step on brake pedal, brake pedal force acts on servo-unit and impels the work of vacuum driving servo-unit after lever amplification.Existing metal paddles arm configuration adopts with support tube and welds, and welding rear supporting tube distortion size is difficult to control; Due to the restriction that some vehicle man machine arranges, pedal arm structure angle of inclination are large, need to increase pedal arm thickness of slab.And be at present adopt welding mode by pedal arm and support tube affixed, pedal assembly should meet reliability requirement as the vitals of vehicle braking system, therefore the intensity of brake pedal arm will be ensured, if there is the generation likely causing great traffic accident of rupturing in weld, and there is labile factor when batch manufacturing in conventional welding manner, and the workpiece do not met the demands by all weld strengths all detects, spend a large amount of manpower and materials: on the cylindrical of support tube, cover has brake check spring, when the many overlaps of remained on surface of welding body, welding slag, when vehicle brake pedal assembly works, constantly can rub with brake check spring, make a noise, brake check spring also finally can be rubbed, not only reduce service life, and serious consequence can be caused.In addition, current antiskid pedal is mostly comparatively coarse, and service life and resistance to abrasion are all general.
Utility model content
The purpose of this utility model is to provide one to ensure dimensional control, can alleviate again the automobile brake pedal arm of pedal arm structural entity weight.
For solving the problems of the technologies described above, the utility model automobile brake pedal arm, comprises pedal arm main body, is respectively equipped with profile hole and pedal at the two ends of described pedal arm main body, and support tube is connected in described profile hole; Wherein said pedal comprises pedal skeleton, the base portion of described pedal skeleton is a framework, the upper and lower of described framework is provided with the strap stiffener connecting described framework left and right sides, and be provided with bed course in described framework, the upper surface of described bed course is provided with antiskid particles; Described profile hole is made up of outside multiple breach of circular hole and circular hole periphery, the upper surface being positioned at described profile hole, the lower surface place of described support tube have the nest bloated respectively, have the filling piece of plastic material in the endoporus between two described nests.
Described strap stiffener is in " people " font.Vertical lattice framing is provided with between described strap stiffener.The height of described strap stiffener and the height of described framework maintain an equal level, and described bed course is higher than described pedal skeleton.The edge of described framework inside is provided with several circular hole ribs.
Multiple breach of described profile hole are distributed in the periphery of circular hole.Described filling piece has the through hole with described support tube dead in line.The two ends of described support tube are provided with the extension be threaded.Described pedal arm main body is provided with reinforced rib.
The utility model automobile brake pedal arm support tube and pedal arm main body adopt the mode of nest axial restraint, multiple breach of the profile hole of pedal arm main body can guarantee that support tube does not rotate relative to pedal arm main body, pedal arm main body and support tube are firmly connected and adopt moulds of industrial equipment to realize, avoid the labile factor of the batch manufacturing that welding manner brings, during the work of vehicle brake pedal assembly, brake check spring is no longer rubbed, and can ensure that brake pedal unit is safe and reliable within the service life appraised and decided.And the distortion that can reduce after support tube welding, can cost be reduced again; Pedal arm body surfaces punching press reinforced rib, can expendable weight under the prerequisite of proof strength, can reduce costs again.In addition, pedal is longer for service life, and antiskid capability is good.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model automobile brake pedal arm is described in further detail.
As shown in Fig. 1 ~ Fig. 5, the pedal arm main body 2 that the utility model automobile brake pedal arm integrated punching is shaping, subsidiary stamping forming reinforced rib 3, for profile hole 6 structure fixing with support tube 1, support tube 1 realizes axial restraint by nest 8, the circular hole periphery of profile hole 6 has multiple breach 5, can guarantee that support tube 1 does not rotate relative to pedal arm main body 2.In addition filling piece 7 can play firm effect further.
Pedal 4 comprises the pedal skeleton 9 that plastics are made, and the base portion of pedal skeleton 9 is a framework, and the upper and lower of framework is provided with the strap stiffener 11 connecting framework left and right sides, and be provided with bed course 10 in framework, the upper surface of bed course 10 is provided with antiskid particles.
Strap stiffener 11 is in " people " font, vertical lattice framing 12 is provided with between strap stiffener 11, the height of strap stiffener 11 and the height of pedal skeleton 9 maintain an equal level, and bed course 10 is higher than pedal skeleton 9 and part covers strap stiffener 11 and lattice framing 12, and this design makes bed course 10 can be more tight with the combination of pedal skeleton 9.
The edge of pedal skeleton 9 inside is provided with several circular hole ribs 13, when bed course 10 is shaping, makes both combinations more firm.
The utility model automobile brake pedal arm support tube and pedal arm main body adopt the mode of nest axial restraint, multiple breach of the profile hole of pedal arm main body can guarantee that support tube does not rotate relative to pedal arm main body, pedal arm main body and support tube are firmly connected and adopt moulds of industrial equipment to realize, avoid the labile factor of the batch manufacturing that welding manner brings, during the work of vehicle brake pedal assembly, brake check spring is no longer rubbed, and can ensure that brake pedal unit is safe and reliable within the service life appraised and decided.And the distortion that can reduce after support tube welding, can cost be reduced again; Pedal arm body surfaces punching press reinforced rib, can expendable weight under the prerequisite of proof strength, can reduce costs again.In addition, pedal is longer for service life, and antiskid capability is good.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the invention spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
