Abstract
The invention relates to a brake system using a hydraulic oil pump to assist in a vehicle. Standard brake assist devices with different specifications and models can be designed according to different vehicle models and load capacities, a high strength and high precision hydraulic oil pump is installed on a speed changing box of the vehicle and connected with a transmission shaft, the hydraulic oil pump is driven by motive power of the transmission shaft during downhill, oil outletting of the hydraulic oil pump is controlled and stopped, the rotating speed of the transmission shaft can be controlled, and thereby the vehicle speed can be controlled.
Description
Technical field
The present invention is a kind of car assisted brake system of hydraulic oil pump of utilizing, can go out the standard brake auxiliary device of different size model according to the difference of vehicle model, the size design of load carrying ability, the automobile that allows as much as possible guarantees automotive safety when lower long slope, avoid the brake failure that causes because of brake drum or the red heating of hair updo.
Background technology
Brake system commonly used has aerodynamic brake and the moving brake of oil, the moving brake of general little automobile oil, large automobile-used aerodynamic brake at present.These two kinds of brake system are also applicable on level road, but all can cause brake drum or hair updo heat, rubescent in the mountain area, during lower long slope, brake drum or dish lose original intensity or size burning under the red state, allow brake failure, cause vehicle to stop, serious meeting causes car crash.Existing solution has several: the 1st, and energy brake, this is in daily use at truck; The 2nd, trickle, this also is truck means commonly used; The 3rd, electromagnetic eddy current brake, this is in daily use at Luxury coach, and effect is all right, but inapplicable on the lorry; The 4th, have the people to install a mill auxiliaries brake disc additional at transmission shaft, except electromagnetic eddy current brake, more than these methods all can't fundamentally solve the potential safety hazard that lower long slope brings.
Summary of the invention
Pump type oil BAS device of the present invention can solve the problem that automobile brings when lower long slope.We are a high strength, the hydraulic oil pump of high precision is contained on the change speed gear box of automobile, be connected with transmission shaft, allow the power of transmission shaft when descending drive hydraulic oil pump, the fuel-displaced size of control and prevention hydraulic oil pump, just can control the rotating speed speed of transmission shaft, thereby regulation speed speed, certain this mode in fact also is a kind of energy conversion device, energy during the automobile lower long slope gets up by oil flow by oil pump, if we stop the size of the amount of flow of oil, oil will the kinetic energy energy transform into heat energy, be gone out dissipation of heat by the hydraulic oil radiator that installs additional again, in order to allow oil reach needed temperature constant state, guarantee the normal operation of parts.
Description of drawings
Accompanying drawing is the fundamental diagram of hydraulic oil pump BAS.Further specify below in conjunction with accompanying drawing: 1. change speed gear box among the figure, 2. hydraulic oil pump, 3. Pneumatic hydraulic fuel tap, 4. height pressure separation device, 5. hydraulic oil radiator, 6. high pressure gas outlet, 7. low pressure gas outlet, 8. pipeline, 9. admission port
The specific embodiment
1. 2. the hydraulic oil pump that has connected in the change speed gear box of existing tip lorry is done larger, and that does is more firm, more accurate, makes its efficient that works together higher.Hydraulic oil pump 2. oil outlet connect a pneumatic high-accuracy hydraulic pressure fuel tap 3., with the brake pedal interlock, but this Pneumatic hydraulic fuel tap 3. nose air intake must install a height pressure separation device additional 4., when the driver gently steps on braking vane, infrabar is used for promoting pneumatic high-precision hydraulic valve 3., can make car retardation or slowly stop, when emergency situation is arranged, one is foot-operated lower, 6. the outlet of height gas can enter a large amount of pneumatic transmissions in the brake system of full car, full car brake system can all start, and vehicle is stopped fast.From Pneumatic hydraulic valve 3. out oil temperature can uprise, at this moment must Pneumatic hydraulic valve 3. out oil 8. send into hydraulic oil radiator with pipeline and 5. cool off, cooled hydraulic oil can enter 2. repeated usage of high-accuracy hydraulic oil pump.
Claims (1)
1. hydraulic oil pump BAS, we are a high strength, the hydraulic oil pump of high precision is contained on the change speed gear box of automobile, be connected with transmission shaft, allow the power of transmission shaft when descending drive hydraulic oil pump, the fuel-displaced size of control and prevention hydraulic oil pump, just can control the rotating speed speed of transmission shaft, thereby regulation speed speed, certain this mode in fact also is a kind of energy conversion device, energy during the automobile lower long slope gets up by oil flow by oil pump, if we stop the size of the amount of flow of oil, oil will be the kinetic energy energy transform into heat energy, by the hydraulic oil radiator that installs additional dissipation of heat is gone out again, in order to allow oil reach needed temperature constant state, guarantee the normal operation of parts.
