Automobile parking braking method and hydraulic parking brake

Abstract

The parked automobile braking method is a manually braking method to produce and accumulate some high pressure braking liquid and energy for braking parked automobile. It has braking control lever and braking executing lever with changeable lever ratio and baking cylinders with changeable number for different braking state. One hydraulic parked automobile brake includes liquid storage, braking handle, brake releasing handle, brake releasing valve, high pressure brake cylinders, low pressure brake cylinder with pressure limiting valve and connecting pipeline. The present invention is used in parked automobile braking as well as traveling automobile braking, if necessary.

Description

technical field [0001] The invention relates to an automobile parking braking method; the invention also relates to an automobile hydraulic parking braking device. Background technique [0002] The current method of parking brake of automobile generally utilizes mechanical transmission to realize parking brake; For car braking, let alone the lever ratio between the brake lever and the pressure end of the brake system can be changed with the lever ratio required by various braking states, because the human physical strength is limited, so its braking effect The force is relatively small. Just can't brake the vehicle that is running and stop very fast, if the brake gap has not been adjusted for a long time, the vehicle that has stopped on the slope can't brake the parked vehicle. Chinese patent announcement number 2359183Y discloses a kind of " automobile brake device " that is used for automobile hydraulic brake system, and it utilizes control valve to control accumulator t...

Problems solved by technology

[0002] The current method of parking brakes for automobiles generally uses mechanical transmission to realize parking brakes; For car braking, let alone the lever ratio between the brake lever and the pressure end of the brake system should be changed with the lever ratio required by various braking states, because the human physical strength is limited, so its braking effect less force

It is impossible to quickly brake the moving vehicle. If the brake clearance has not been adjusted for a long time, the vehicle that has stopped on the slope cannot brake the parked vehicle.

Chinese patent announcement number 2359183Y discloses a kind of " automobile brake device " that is used for automobile hydraulic brake system, and it utilizes control valve to control accumulator to increase hydraulic braking force, but this accumulator structure is complicated, existing automobile It has no design itself, and it needs power when storing energy, so it is neither suitable for parking nor used for car modification
