Description
Technical field
The utility model relates to the parallel fluid power retarder that a kind of gear engagement is regulated speed ratio.
Background technique
CN200910051459.3 discloses a kind of automotive energy-saving emission-reducing hydraulic retarder; Its purpose provides a kind of be installed in oil pump and hydraulic system parallelly connected with it on the large and medium-sized automobile gearbox output shaft; It not only possesses the function of Vehicle Hydraulic Retarder; And the kinetic energy can reclaim automobile brake time the and utilize again in starting (or afterburning) time, the toxic emission when also having reduced starting, thus realize energy-saving and emission-reduction.This technological scheme comprises: parallelly connected with the automobile gearbox output shaft, in conjunction with or throw off conveniently, can throw off when there is fault in system; But vehicle is cruising still, and the energy transfer of its accumulation of energy, exoergic is without the mechanical system of former gearbox, but directly output shaft of gear-box is linked to each other with automobile axle by clutch; Alleviated the load of gearbox, remarkable energy saving effect is arranged, exoergic is afterburning when vehicle launch; Improve the operating mode of motor, reduced discharge of harmful gases; Can strengthen priming speed, improve efficiency of operation.It is slow into flexible fluid power to become the mechanical rigid braking, when improving riding comfort, has prolonged the working life of system of vehicle transmission and braking system.Its deficiency is:
1, because what adopt is that first poultry can just can be kept deceleration, this retarder poultry not can situation under can not bring into play good retarded acting, therefore big limitations the extensive use of this invention.
2, because this invention adopts poultry can device energy storage slow, can the device energy storage during when poultry to maximum value, this retarder is just no longer brought into play retarded acting, therefore big limitations the extensive use of this invention.
3, need on car body, increase fuel tank and poultry ability device, retarder is had higher requirement at the integral layout of car body, increase the difficulty that retarder is installed and realized.
4, can reach thousands of N.m because this invents available slow resisting moment (on the wheel), therefore the hydraulic pressure components and parts had higher requirement.
5, this invention needs to increase by one group of gear and clutch, has increased the installing space of gearbox and retarder greatly, has increased weight, has strengthened the difficulty of installing and keeping in repair, and has limited application area.
Summary of the invention
The purpose of the utility model provides the parallel fluid power retarder that a kind of, cost less demanding to part manufacturing process two gear engagement low and easy for installation and that low-speed performance is good are regulated speed ratio.
The technical solution of the utility model is the parallel fluid power retarder that said gear engagement is regulated speed ratio, and its special way is: by the train that is provided with in gearbox and the gearbox odd-side, be located at gearbox odd-side outside and form with the impeller of rotor assembly of the coaxial hydrodynamic retarder that is rotatably connected of said train.
As preferably: the driven gear of fixing on the jack shaft that said train is laterally arranged by driving gear, gearbox odd-side and the said output shaft of gear-box of the overhead cover of output shaft of gear-box is formed; Said driving gear and said driven gear all adopt the original gear of gearbox; The rotating ratio of said driving gear and said driven gear is greater than 1.
As preferably: the coaxial installation of impeller of rotor assembly with hydrodynamic retarder is passed behind the gearbox odd-side housing through bearing in the end of said jack shaft.
As preferably: the wherein a kind of Placement with straight toothed spur gear, helical gear, herringbone gear is chosen in the engagement between said driving gear, driven gear.
As preferably: said driving tooth bye is enclosed within on the output shaft of gear-box, is connected with output shaft of gear-box through synchronizer.
As preferably: said jack shaft links through spline and impeller of rotor assembly.
Compared with prior art, the advantage of the utility model:
⑴ process respectively because the gear in the train is two parts, and the difficulty of the processing technology of part reduces greatly.
⑵ parallel fluid power retarder adopts gear transmission moment of torsion, the working efficiency and the working life of having improved parallel fluid power retarder.
⑶ increased the moment of torsion of output shaft of gear-box greatly because the rotating ratio of train greater than 1, makes the rotating speed of parallel fluid power retarder rotor part be higher than the rotating speed of output shaft of gear-box, improved the usability of parallel fluid power retarder.
⑷ the output shaft of parallel fluid power retarder and gearbox is through the gear pair parallel connection; Make parallel fluid power speed buffer structure compact; Gross weight alleviates, and retardation efficiency improves greatly, and assembling and entrucking are convenient; Reduced cost, and the technology capability of parallel each component part of fluid power retarder is better.
