Abstract
A telemechanical vacuum servo-brake, which is characterized in that : a brake pedal is connected with a master cylinder by means of a connecting rod; the master cylinder is connected with an auxiliary cylinder by means of a pipeline; the auxiliary cylinder is connected with an rear wheel cylinder by means of the pipeline; an air cleaner, a control valve and a servo vacuum chamber are arranged on the auxiliary cylinder; wherein, the servo vacuum chamber is connected with a vacuum tube by means of the pipeline, and the vacuum tube is communicated with a vacuum pump air pipe of a motor by means of the pipeline. The utility model has the advantages that the labor intensity of drivers can be reduced and the adequate work pressure of the pipeline can be ensured by pressurization, and thus the braking effect can be improved; in addition, the installation position of the supercharger can be chosen freely without the special limit of the cab.
Description
Technical field: the utility model relates to a kind of telemechanical formula servo vacuum brake equipment (vacuum booster brake) that is used for three-wheeled farm transport vehicle.
Background technology: what three-wheeled farm transport vehicle of the prior art adopted is direct acting vacuum servo brake device (vacuum-assisted brake).Owing to its structural reason, exist the labour intensity that can only alleviate chaufeur, and brake pressure variations is very little.The braking force deficiency is accidents caused easily when vehicle heavy duty or overload.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and provides a kind of by supercharging, guarantees that pipeline has enough operation pressures, braking failure-free telemechanical formula servo vacuum brake equipment when vehicle heavy duty or overload.For achieving the above object, the utility model adopts following technical proposals: telemechanical formula servo vacuum brake equipment, comprise brake pedal (1), brake pedal (1) is connected with master cylinder (2) by connecting rod, master cylinder (2) is connected with auxiliary cylinders (3) by pipeline, auxiliary cylinders (3) is connected with rear wheel cylinder (8) by pipeline, auxiliary cylinders (3) is provided with airfilter (4), control cock (5) and servo vacuum air chamber (6), wherein servo vacuum air chamber (6) links to each other with vacuum cylinder (7) by pipeline, and vacuum cylinder (7) communicates with vacuum pump tracheae on the electrical generator by pipeline.
Characteristics of the present utility model are: decapacitation alleviates outside the labour intensity of chaufeur, can also guarantee that pipeline has enough operation pressures by twice supercharging, improves braking effect, and the installation site of blwr can freely select, and is not subjected to the restriction of cab space.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
With reference to Fig. 1, telemechanical formula servo vacuum brake equipment, comprise brake pedal 1, brake pedal 1 is connected with master cylinder 2 by connecting rod, master cylinder 2 is connected with auxiliary cylinders 3 by pipeline, and auxiliary cylinders 3 is connected with rear wheel cylinder 8 by pipeline, and auxiliary cylinders 3 is provided with airfilter 4, control cock 5 and servo vacuum air chamber 6, wherein servo vacuum air chamber 6 links to each other with vacuum cylinder 7 by pipeline, and vacuum cylinder 7 communicates with vacuum pump tracheae on the electrical generator by pipeline.
Principle of work: after stepping on brake pedal, connecting rod promotes the piston in the master cylinder 2, produces high pressure oil in the oil cylinder, promote the piston of auxiliary cylinders 3 by pipeline, open servo vacuum air chamber 6 simultaneously, promote the piston of auxiliary cylinders 3, thereby make auxiliary cylinders 3 produce higher pressure oil control rear wheel cylinder 8.
