Abstract
The utility model relates to a hydraulic type exhaust braking device which consists of a pedal assembly, a master cylinder, an oil pipe, a slave cylinder, a position limiter, a hydraulic type exhaustshutter and the like, wherein the brake pedal is connected with the master cylinder; the master cylinder is connected with the slave cylinder and the hydraulic type exhaust shutter through the oil pipe; during breaking, the pedal is stepped upon so as to push the piston of the master cylinder; brake fluid flows to the slave cylinder so as to force the piston of the slave cylinder to move outwardsunder the action of the oil pressure, thereby pushing the hydraulic type exhaust shutter to open a butterfly valve so as to achieve exhaust brake; when the pedal is released, the master cylinder and the slave cylinder return under the action of the return spring, thereby pressing the brake fluid back to the master cylinder and braking off. The utility model has the characteristics of simplicity, practicality as well as simple and convenient operation.
Description
Technical field:
The utility model belongs to the manufacturing field of low-speed cars, especially relates to a kind of fluid pressure type exhaust braking.
Background technology:
The braking, in ride safety of automobile in occupation of consequence.For the automobile that often travels in the mountain area, especially continuously lower long slope lowers or when keeping stabilizing speed for a long time and constantly, only depend on service braking system to reach the purpose of stabilizing speed, may reduce the brake efficiency that causes brake system because of brake overheating, in addition entirely ineffective.
Summary of the invention:
The utility model has proposed a kind of simple in structure, economical and practical fluid pressure type exhaust braking at the problems referred to above, when having guaranteed the oil brake lower long slope and can stabilizing speed can guarantee the effect of brake efficiency again.
The technical scheme that its technical matters that solves the utility model adopts is to implement like this: this device comprises master cylinder and pedal assembly, oil pipe, wheel cylinder, fluid pressure type exhaust shutter, and it is characterized in that: pedal assembly is connected with wheel cylinder by oil pipe with master cylinder.Need the glancing impact push down on the pedal, promote total pump piston, the brake oil flow wheel cylinder forces wheelcylinder piston outer moving under the oil pressure effect, opens butterfly valve realization energy brake thereby promote the fluid pressure type exhaust shutter; When unclamping pedal, master cylinder and wheel cylinder be return under the pull back spring effect, and braking liquid is pushed back master cylinder, brake off.
Use energy brake not only can guarantee traffic safety during lower long slope, also can lower car side brake and Tyte Wear, and help keeping the normal temperature of driving engine and improve engine life.
That the fluid pressure type exhaust braking has is simple and practical, handle light characteristics.
Description of drawings:
Fig. 1 is the utility model structural representation
1. pedal assemblies among the figure, 2. master cylinder, 3. oil pipe, 4. wheel cylinder, 5. limiting stopper, 6. fluid pressure type exhaust shutter.
The specific embodiment:
Embodiment 1: the utility model comprises compositions such as pedal assembly 1, master cylinder 2, oil pipe 3, wheel cylinder 4, limiting stopper 5 and fluid pressure type exhaust shutter 6.
Embodiment 2: push down on the pedal assembly 1, master cylinder 2 be at the promotion lower compression braking liquid of pedal assembly 1, and the brake oil flow wheel cylinder forces wheel cylinder 4 to move outside under the oil pressure effect, opens butterfly valve and realize energy brake thereby promote the fluid pressure type exhaust shutter; When unclamping pedal, master cylinder and wheel cylinder be return under the pull back spring effect, and braking liquid is pushed back master cylinder, brake off.
