Abstract

An automobile pump retarder using principles of pump compression belongs to automobile auxiliary braking system and is applicable to automobile assembling manufacturing industry. A transmission mechanism, a mechanical pump, an adjusting valve, a controller and an energy accumulator are added to an automobile transmission system. Work of the mechanical pump compresses system media to obtain reverse thrust braking torques of different sizes so as to force retardancy of the automobile and guarantee safe driving. In the meantime, high pressure media generated by the system is delivered into the energy accumulator driven by an engine, so that power consumption of the engine is reduced, power of the engine is improved, and economization and fuel saving of the engine are achieved. The automobile pump retarder is suitable for a driving automobile, especially for constant speed control of an automobile driving down a long slope.

Description

A kind of automotive pump formula retarder
Under technical field: the present invention relates to a kind of automotive pump formula retarder, is a kind of auxiliary brake device for automobile, is mainly used in the automobile in going, and particularly auxiliary braking and the constant sped control during lower long slope belongs to the car assembling manufacture.
Background technology: the general-utility car brake system mainly is divided into two kinds of service brake and braking during standstills, and the middle-and-high-ranking car of part just disposes emergency brake, safety arrestment and complemental brake system; Wheeled braking is also named in service brake, divides two kinds of shoe drum and caliper discs, and big-and-middle-sized passenger and freight car is many with the former; Dolly adopts the latter more or uses with, and service brake is dynamic friction, because Occupation coefficient is high; Cal val is big, and it is not enough and lost efficacy to be prone to braking force, and the good decelerating vehicles of the braking during standstill of launching the static friction mode this moment; So large and medium bus in motion, particularly lifting capacity is big, and service braking system often breaks down when lower long slope; Traffic accident happens occasionally, and brings loss for people's lives and properties.For fear of frequent use service brake, the stable control speed of a motor vehicle increases traffic safety, and the big-and-middle-sized passenger and freight car of part begins choosing dress complemental brake system, like energy brake, retarder etc.Now retarder has only two kinds of current vortex retarder and hydrodynamic retarders, the current vortex retarder utilization be generator principle, it is simple in structure, reaction is fast, but slowly slowly, heat declines greatly; The hydrodynamic retarder utilization be the hydraulic coupler principle, but complex structure, make difficult, cost is high.What the present invention adopted is pump formula contraction principle, fast slowly, simple in structure, reliable and stable.
Summary of the invention: the technical matters that the present invention solves is, on automobile, increases a kind of complemental brake system, can avoid using service brake continually through this device, and service vehicle is slow, particularly can the permanent car controlling speed of pulsation-free when lower long slope, guarantee traffic safety.The technical scheme that this device adopted is to fasten in vehicle transmission to increase a pair of gear pair, on one of them gear power-transfer clutch is housed, and is used for incision and breaks off retarder; Drive the mechanical pump acting through transmission device again; The compression of medium in the system is formed high pressure potential energy, obtain a deboost moment thus, pass to transmission system and running device again; Form the advance resistance of vehicle, realize that with this vehicle is slow.Chaufeur can obtain the different security moving velocity through nigh controller is installed.Simultaneously, the high-pressure medium that system is produced is sent to the energy storage by engine drives, can reduce engine power consumption, improves engine power and realizes economic fuel-economizing.This beneficial effect of the invention is that auxiliary service braking system forces vehicle slow; Permanent reposefully car controlling speed during lower long slope particularly; Avoid service brake to lose efficacy, increase traffic safety, simultaneously; Improve engine power and realize economic fuel-economizing, this contrive equipment is fast slowly, reliable and stable, simple in structure, with low cost, convenient for installation and maintenance.
Description of drawings: implement row below in conjunction with accompanying drawing the present invention is further specified.
1, escapement; 2, fork; 3, gear pair; 4, transmission system; 5, power-transfer clutch; 6, plunger pump; 7, dielectric chamber; 8, energy storage; 9, driving engine; 10, controller; 11, control cock.
Fig. 1 is an one embodiment of the invention running part constructional drawing, drives three radial plunger pump actings through escapement.
Fig. 2 is pump-up system constructional drawing of one embodiment of the invention, and three plunger pumps are imported and exported through the connection pipe parallel connection.
The specific embodiment: in Fig. 1, transmission system (4) passes to escapement (1) through gear pair (3), power-transfer clutch (5) with gyroscopic movement, drives plunger pump (6) acting, compression system medium through fork (2) again;
In Fig. 2, high-pressure medium is given the different lock torque of transmission system (4) through control cock (11), controller (10) adjustment anti-pass, gets into the energy storage (8) that is driven by driving engine (9) simultaneously, and superpressure is partly got back to dielectric chamber (11).

Claims (2)

1. automotive pump formula retarder; This device is installed in vehicle transmission and fastens, and is connected and composed by transmission device, mechanical pump, control cock, controller, and communicates with energy storage by engine drives; It is characterized in that automotive transmission passes through transmission device and drive the mechanical pump acting; The compression system medium obtains different anti-pushing kinetic moments through control cock, controller adjustment again, forces car retardation.
2. according to the described retarder of right (1), it is characterized in that the high-pressure medium that system produces can be sent to the energy storage by engine drives, reduces engine power consumption.
