Abstract

A combined brake-acceleration pedal for car features that the stroke of said pedal is divided into braking segment, short isolating segment and accelerating segment. The magnetic attraction of fixed magnetic ring to armature disk is trasnferred via push rod to the piston of braking pump for braking the car. The armature disk connected to a pull string of throttle and said pedal arm can synchronously rotate around a fixing axle.

Description

------quickens the combination pedal in automobile-used braking

Affiliated technical field

The present invention relates to automobile-used brake pedal and acceleration pedal, especially a kind of automobile-used braking---quicken the combination pedal.

Background technology

Existing automobile-used brake pedal and acceleration pedal are installed in the lower right of bearing circle side by side.Automobile driver is braked from finding dangerous overslaugh thing to actual beginning the on the working direction, needs the time of a segment length.This makes sky sail the time, and the distance of travelling in sky is sailed the time is free travel distance.The sky time of sailing is generally 0.7--0.8 second.Sky is sailed constituting of time:

The T=sensation reflection time+time of trampling+step on to die the time

(0.4-0.5 second) (about 0.2 second) (about 0.1 second)

The time of trampling is: leave acceleration pedal to the time that is placed on the brake pedal from right crus of diaphragm.

Along with the development and the development of technology of society, the recoverable amount and the productive output of automobile increase suddenly.The speed of automobile also increases to car 130-240Km/h lorry 90-120Km/h by early stage 10Km/h.40-50% is arranged in the traffic accident according to statistics, and oversize or emergency braking breaks away out of control etc. and takes place because of stopping distance.Traffic accident causes the heavy losses of personnel and property.The traffic accident social effects of pollution that become international.

Summary of the invention

Sail the time in order to shorten about 0.2 second sky, make vehicle enter actual braking mode in advance, the minimizing accident.The present invention will provide a kind of automobile-used braking-acceleration combination pedal.

The technical solution adopted for the present invention to solve the technical problems is, the magnetic ring body magnetic that rigidly fix a unification armature disc coaxial with the master brake cylinder piston cylinder, center shaft is to there being tapped through hole to be combined with double-screw bolt, double-screw bolt one end ball hole contains the bulb of push rod, the push rod other end passes the central through hole of magnetic ring body, promote the piston of master brake cylinder, the vehicle full application of brake.Armature disc can be agitated around the axle that rigidly fixes of its back side lower edge tangential direction.Brake control lever is coaxial with the angle interaction with armature disc, and promptly the wedged air gap between push down on the pedal armature disc and the magnetic ring body increases, and push rod retreats that piston is stressed to be reduced simultaneously, lifts right crus of diaphragm, floats because the magnetic-drag pedal is followed right crus of diaphragm, and push rod advances, the stressed increase of piston.After pedal came downwards to the suitable distance of push rod disengaging piston, the earhole of armature disc upper rear portion and pull bar lower end were hinged, the bolt traction throttle drag-line line of the upper end of pull bar on connecting panel, and driving engine quickens.In order to prevent that foreign matter from falling into air gap, the bellows with rubber or plastics are made seals air gap.

The invention has the beneficial effects as follows that the power that scrunches the when person for driving a car must possess the former brake pedal emergency braking of operation just can be removed the full application of brake state of combination pedal.Break away from pedal as long as lift right crus of diaphragm or side direction, braking produces immediately.Before multiple reason enters stupor, possesses this kind operator perforniance.Emergency braking belongs to person for driving a car's stress situation, and the combination pedal is difficult for taking place misoperation, its operating sequence strong interference immunity, simple, reliable.Effective and rapid from quickening to enter braking, shortening about 0.2 second is that sky is sailed the time.Person for driving a car's operative combination pedal is light, laborsaving.

The specific embodiment

Magnetic ring body (1) is that Qu Tiehuan body (2) and permanent-magnetic clamp (4) are formed, and is full of the slit with chill casting filler (3).Magnetic ring body (1) is by flanged hollow bushing (5) and support base plate (27) welding.Armature disc (15) central axis direction has tapped through hole, and the spherical hole of double-screw bolt (16) one ends contains the bulb of push rod (18) one ends, with the reducing method bulb is not deviate from.The piston (not shown) of the other end conflict master brake cylinder of push rod (18), the other end of double-screw bolt (16) has six side's blind holes and nut (17) locking, the lower edge tangential direction at armature disc (15) back side has two coaxial apertures, rack side plate (24) has two equidirectional holes, pedal arm (22) also has the hole, garden, and axle (21) is through all holes together.Armature disc (15), pedal arm (22) is realized coaxial with the angle interaction.Also have the spiral shell inspection (19-20) of adjustable pedal (23) height at armature disc (15) back side, support base plate (27) is fixing by four bolts (25-26) and compartment coaming plate (31).Throttle drag-line (29) warp of introducing outside the railway carriage or compartment and the drag-line cover (30) of support base plate (27) welding, the bolt (7) on drag-line line (6) and the connecting panel (8) is fixed.Connecting panel (8) links with axle (9) with pull bar (10).There is bolt (11-12) at the middle part of pull bar (10), and the lower end of pull bar (10) is with the back side earhole hinge joint of axle (13) with armature disc (15).Pull bar (10) is also riveted spring leaf (14) makes pull bar (10) and armature disc (15) upper end open that the trend of increasing be arranged.In order to prevent that foreign matter from falling into air gap, the bellows sealing air gap that place, outer garden also has rubber or plastics to make.(not shown)

The combination pedal is to adjust like this, rotates double-screw bolt (16) effective length of push rod (18) is increased, and keeps cooresponding wedge air gap up to the faying face of magnetic ring body (1) and armature disc (15).Block nut (17), this moment, vehicle was in the full application of brake state.Stoplight stop lamp is bright, and push down on the pedal (23) extinguishes up to stoplight stop lamp, and the stroke of this pedal (23) is called braking distance.Step on slightly down again, be equivalent to the play motion of former brake pedal, be called the isolation stroke.The bolt (11-12) of adjusting pull bar (10) middle part this moment makes the back side of its conflict armature disc (15).Step under continuing, then throttle drag-line line (6) is pulled, and driving engine quickens.Step on driving engine under continuing the most at a high speed, be called accelerating travel.

The action of combination pedal and pedal (23) buoyancy change as follows, and during Parking, the combination pedal is in the full application of brake state.The person for driving a car is at first with pedal (23) under the right crus of diaphragm palm, because the air gap of this moment is little, magnetic-drag is big, so must use the power that scrunches that is equivalent to former brake pedal emergency braking, descending along with pedal (23), because the increasing of air gap, the buoyancy of pedal (23) is die-offed, when push rod (18) broke away from the master brake cylinder piston, braking was all removed.Right crus of diaphragm was followed and was dropped on the cabin floor this moment, and through isolating stroke, the buoyancy and the attitude of pedal (23) have entered the serviceability that is equivalent to former acceleration pedal.Start vehicle, it is reached the most at a high speed.

As long as lift right crus of diaphragm or abandon pedal (23), its braking force increases suddenly with the come-up of pedal (23), up to full application of brake.
