Utility model content
The purpose of this utility model is just to provide a kind of drum-type automobile braking device to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of drum-type automobile braking device, comprises brake pedal, push rod, master cylinder piston, master brake cylinder, oil pipe, brake wheel cylinder, wheelcylinder piston, brake wheel, friction lining, brake shoe brake cheek, adjustment bolt, pull back spring and pin; It is characterized in that: described push rod is between brake pedal, master brake cylinder and be fixedly connected with it, described master cylinder piston to be located within master brake cylinder and to be connected with push rod, the left and right two ends of described oil pipe are connected with master brake cylinder, brake wheel cylinder respectively, described wheelcylinder piston to be located within brake wheel cylinder and to be fixedly linked with brake shoe brake cheek, described friction lining is connected with brake shoe brake cheek, described left and right brake shoe brake cheek is connected by adjustment bolt, and described pull back spring is positioned at brake wheel cylinder bottom and is connected with pin.
Preferably, described friction lining is provided with semi-open type groove and multiple little louvre.
Preferably, two ends, described adjustment bolt left and right are provided with adjusting knob.
Preferably, described pull back spring is connected with pin winding screw.
The beneficial effects of the utility model are: this drum-type automobile braking device is easy to use, good braking effect, and brake continuously can be avoided to cause brake facing Yin Gaowen and produce heat fade phenomenon, and avoid complex structure part many, braking gap must adjust, and makes maintenance not easily.
Accompanying drawing explanation
Fig. 1 is structural representation described in the utility model;
In figure: 1, brake pedal, 2, push rod, 3, master cylinder piston, 4, master brake cylinder, 5, oil pipe, 6, brake wheel cylinder, 7, wheelcylinder piston, 8, brake wheel, 9, friction lining, 10, brake shoe brake cheek, 11, adjustment bolt, 12, pull back spring and 13 pins.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model provides a kind of technical scheme: a kind of drum-type automobile braking device, comprises brake pedal 1, push rod 2, master cylinder piston 3, master brake cylinder 4, oil pipe 5, brake wheel cylinder 6, wheelcylinder piston 7, brake wheel 8, friction lining 9, brake shoe brake cheek 10, adjustment bolt 11, pull back spring 12 and pin 13, described push rod 2 is positioned at brake pedal 1, be fixedly connected with it between master brake cylinder 4, described master cylinder piston 3 to be located within master brake cylinder 4 and to be connected with push rod 2, described oil pipe 5 is left, right two ends respectively with master brake cylinder 4, brake wheel cylinder 6 connects, described wheelcylinder piston 7 to be located within brake wheel cylinder 6 and to be fixedly linked with brake shoe brake cheek 10, described friction lining 9 is connected with brake shoe brake cheek 10, described friction lining 9 is provided with semi-open type groove and multiple little louvre, water can be made to flow out along groove, in addition, friction coefficient can be increased, make itself and brake wheel 8 friction braking more effective, brake continuously can be avoided to cause brake facing Yin Gaowen and produce heat fade phenomenon, described left and right brake shoe brake cheek 10 is connected by adjustment bolt 11, described adjustment bolt about 11 two ends are provided with adjusting knob, adjustable brake shoe brake cheek 10, it is made to brake better, described pull back spring 12 is positioned at brake wheel cylinder 6 bottom and is connected with pin 13 winding screw, can effectively balance pull back spring 12.
Working process: use pedal brake pedal, promote master cylinder piston through push rod, master cylinder piston is to hydraulic fluid force feed in master brake cylinder, hydraulic pressure increases, and hydraulic oil goes to brake wheel cylinder pressure through oil pipe, promotes wheelcylinder piston, drive brake shoe brake cheek, friction lining and brake wheel friction, thus realize automotive drum type braking; Loosen the brake, brake shoe brake cheek retracts by retracing spring, promotes wheelcylinder piston, and now the hydraulic pressure of brake wheel cylinder is large, and hydraulic oil flows to master brake cylinder reverses through oil pipe again, promotes master cylinder piston, push rod, thus realization brake resets.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.In addition, be to be understood that, although this specification sheets is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of specification sheets is only for clarity sake, those skilled in the art should by specification sheets integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
