Description
Technical field
The utility model relates to vehicle drive auxiliary device, particularly a kind of automobile start assisting device.
Background technology
During existing manual-gear vehicle starting, need open the throttle wide to improve engine speed (approximately 1500 turn), unrelated between the power-transfer clutch of manual automobile, brake and accelerator, need chaufeur to carry out manual manipulation, reach good driving effect, chaufeur must be optimized adjusting to the above-mentioned process of controlling.The unobstructed operation of vehicle generally to carry out these operations not difficult, but in upward slope process, in the time of need to stopping while running into traffic congestion, this process more complicated, frequent operation easily causes error, if these actions can not get position or coordinate not coordinating, the as easy as rolling off a log automobile that causes retreats when starting, leads to traffic accident.Power-transfer clutch coordinates the bad violent shake of driving engine and the flame-out phenomenon of also easily occurring with throttle, slope starting is difficult to grasp, and increases the shortcomings such as wearing and tearing of fuel oil consumption and clutch components.In order to address this problem, people have invented Automatic Transmission, adopt the automatic gear car of Automatic Transmission when going up a slope starting, effectively to avoid the problem of start-backing, but result relative complex, and manufacturing cost and energy consumption are higher, reliability also decreases.
Utility model content
The utility model object is to overcome the defect that prior art exists, and gentle start when a kind of automobile slope starting is provided, reduces the automobile start assisting device that fuel oil consumption and clutch components wear and tear.
The utility model proposes for achieving the above object following technical scheme: a kind of automobile start assisting device, comprise piston and hydraulic gear and infusion pipeline, fluid reservoir and by-pass valve control, it is characterized in that: in hydraulic cavities, be provided with the piston moving up and down, be linked with piston all-in-one-piece piston rod and car clutch pedal or disengaging yoke; Hydraulic cavities top and be peripherally equipped with guide collar at piston rod, has deflation hole in guide collar; In hydraulic cavities bottom, be equipped with respectively and the hydraulic pipe communicating in chamber, hydraulic pipe connects check valve and leads to fluid reservoir, under hydraulic cavities, export on the boss that leads to check valve afterbody spring is set, hydraulic pipe is connected with fluid reservoir by electromagnetic valve, and braking liquid regularly regulates and controls the flow of liquid outflow with the descending speed of control plunger at pressure one.
The valve sheet middle part of described check valve is provided with the Flow Limit drilling for braking liquid circulation, at the liquid inflow entrance place of check valve, filtering net is set.
The utlity model has following distinguishing feature: do not change existing autoclutch and brake system structure, automobile start assisting device has just solved the problem of above existence well, automobile lifts pedal of clutch at 1 gear or when starting of reversing gear, power-transfer clutch automatic steady engages, without open the throttle wide, idling mode (engine speed approximately 800 turns) gets final product gentle start, also can gentle start without parking brake during automobile slope starting, driving engine is without violent shake and flame-out phenomenon, reduce the wearing and tearing of fuel oil consumption and clutch components, avoided the hidden trouble of traffic bringing due to misoperation.; By the control of power supply being realized to start assisting pattern and former car, play step mode and can freely change, automobile is controlled more simple and convenient, improves the economy that automobile uses and the traveling comfort driving a car.
Accompanying drawing explanation
Accompanying drawing is the utility model structural representation.
In figure: 1 piston rod; 2 deflation holes; 3 guide collar; 4 pistons; 5 seal rings; 6 springs; 7 check valves; 8 Flow Limit drillings; 9a hydraulic pipe; 9b hydraulic pipe; 10 filtering nets; 11 hydraulic cavities; 12 electromagnetic valves; 13 engaging lugs; 14 fluid reservoirs.
The specific embodiment
As shown in drawings, the automobile start assisting device that the utility model provides, mainly by piston, piston rod and hydraulic gear and infusion pipeline, fluid reservoir and by-pass valve control, in hydraulic cavities 11, be provided with the piston 4 moving up and down, in piston 4 outer rims, with hydraulic cavities 11 contacts site, seal ring 5 be housed; Be linked with car clutch pedal or disengaging yoke with piston 4 all-in-one-piece piston rods 1, the engaging lug 13 of hydraulic cavities 11 bottom surfaces is fixed on the external suspension bracket of automobile; Hydraulic cavities 11 tops and be peripherally equipped with guide collar 3 at piston rod 1, have deflation hole 2 in guide collar 3; In hydraulic cavities 11 bottoms, be equipped with respectively and the hydraulic pipe 9a communicating in chamber, hydraulic pipe 9b, hydraulic pipe 9a connects check valve 7 and leads to fluid reservoir 14, the valve sheet middle part of check valve 7 is provided with the Flow Limit drilling 8 for braking liquid circulation, in 11 times outlets of hydraulic cavities, lead to check valve 7 and spring 6 is set on the boss of valve afterbody, the liquid inflow entrance place of check valve 7 arranges filtering net 10; Hydraulic pipe 9b is connected with fluid reservoir 14 by electromagnetic valve 12, and the braking liquid in hydraulic pipe 9a is controlled by check valve 7 and Flow Limit drilling 8, and the braking liquid in hydraulic pipe 9b is controlled open and close by electromagnetic valve 12; During work, pass through two cover infusion pipeline assemblies conversions and use, braking liquid regularly regulates and controls the flow of liquid outflow with the descending speed of control plunger 4 at pressure one, finally realizes the smooth engagement of autoclutch.
Working process of the present utility model: piston rod 1 drives piston 4 and seal ring 5 upward movements along guide collar 3 centers when stepping on car clutch pedal separation, piston 4 upper gas discharge to reduce air resistance through deflation hole 2, the piston 4 interior generation negative-pressure sucking of hydraulic cavities 11 below, liquid flows into hydraulic cavities 11 through hydraulic pipe 9a and hydraulic pipe 9b, when automobile suspension enters 1 gear or reverse gear, gear on-off switches on power and closes hydraulic pipe 9b by electromagnetic valve 12, when lifting pedal of clutch, under clutch driving disc pressure-acting, by pedal of clutch or disengaging yoke, drive piston 4 to move downward generation certain pressure, the filtering net 10 of liquid on can only the check valve 7 in hydraulic pipe 9a, Flow Limit drilling 8 is flowed out, control plunger 4 descending speeds are realized power-transfer clutch and are slowly engaged, reach automobile balance starting, piston 4 upward movements during as the clutch of needs secondary, hydraulic pipe 9b is now in closed condition, and when the interior generation negative-pressure sucking of hydraulic cavities 11 is greater than spring 6 pressure, the check valve 7 of liquid in hydraulic pipe 9a flows into hydraulic cavities 11 and completes separating action.Automobile when hanging into other gear, gear on-off access failure power supply, the electromagnetic valve 12 on hydraulic pipe 9b is in opening, when lifting pedal of clutch, the liquid in hydraulic cavities 11 flows back to fluid reservoir 14 fast through hydraulic pipe 9b, realizes power-transfer clutch and engages fast.
