Abstract
The utility model discloses an installation structure of a mid-hydraulic retarder, which comprises a spline shaft, wherein the two ends of the spline shaft are connected with the end parts of two transmission shafts in a manner of flange connection; a flange comprises a first flange, a second flange, a third flange and a fourth flange; and the first flange and the second flange are respectively and fixedly connected on the two ends of the spline shaft, the third flange and the fourth flange are respectively and fixedly arranged on the end parts of the two transmission shafts, the first flange is fixedly connected with the third flange via a bolt, and the second flange is fixedly connected with the fourth flange via a bolt. The two ends of the spline shaft of the hydraulic retarder are respectively and fixedly connected with the flanges, and the flanges are connected with the flanges which are fixedly arranged on the transmission shaft via the bolts, so that the hydraulic retarder can be installed between the two transmission shafts of a car to balance the loads of a gearbox and a rear axle; and the installation is convenient to carry out, so that the damages of the gearbox and the rear axle are small.
Description
Technical field
The utility model relates to vehicle auxiliary braking technical field, is specifically related to a kind of mounting structure that is arranged on the hydrodynamic retarder on truck drive shaft.
Background technique
Auto brake system is one of most important system in vehicle safety travel.Improvement along with engine technology development and road conditions, the travelling speed of automobile and single range ability all have a great development, the kinetic energy that travels significantly improves, thereby makes traditional friction disk type braking device more and more can not adapt to long-time, high-intensity need of work.Owing to frequently or for a long time using Service Brake, the overheated Braking efficiency heat fade phenomenon of friction plate appears, cause braking failure when serious, threaten traffic safety, vehicle is also because frequent replacing brake shoe and tire cause the increase of cost of transportation.In order to address this problem, the various vehicle auxiliary braking systems that arise at the historic moment are developed rapidly, and hydrodynamic retarder is exactly wherein a kind of.
Traditional hydrodynamic retarder comprises heat exchanger, rotor, stator and hydrodynamic retarder housing, has fuel reserve tank and active chamber on the hydrodynamic retarder housing, and rotor is to be fixed together with car transmissions, and automobile is when motion, and rotor also can rotate.During hydrodynamic retarder work, pressurized air enters fuel reserve tank, and between oil pressure feed liquor power retarder stator and rotor in fuel reserve tank, hydrodynamic retarder is started working, and rotor drives fluid and rotates around axis; Simultaneously, fluid moves along the rotor blade direction, gets rid of to stator, and stator vane produces reaction to fluid, and the fluid outflow stator goes back to impact rotor again, so just forms the resisting moment to rotor, hinders the rotation of rotor, thereby realizes the decelerating effect to vehicle.
Existing hydrodynamic retarder is installed on gearbox, and the female splined shaft of hydrodynamic retarder is enclosed within on the male splined shaft that gear-box axle goes out, and the other end is connected with the flanged surface of truck drive shaft by bead.Adopt this mounting structure, gearbox had both been born the inertia impact that the weight of hydrodynamic retarder and when driving produce, and bore again the moment of torsion of hydrodynamic retarder self, affected the working life of gearbox.
The model utility content
For above shortcomings in prior art, the utility model provides a kind of mounting structure of center-positioned hydraulic retarder, and by this mounting structure, hydrodynamic retarder can be arranged on truck drive shaft, and is little, easy for installation to gearbox and back axle harm.
To achieve these goals, the technical solution adopted in the utility model is as follows:
The mounting structure of center-positioned hydraulic retarder comprises splined shaft, and described splined shaft is connected with the end of transmission shaft by the mode that flange connects.
Further, described flange comprises the first flange, the second flange, three-flange and the 4th flange, described the first flange and the second flange are fixedly connected on respectively the two ends of splined shaft by spline, described three-flange and the 4th flange are fixedly installed on respectively the end of transmission shaft and the first flange and three-flange and are bolted to connection, and the second flange and the 4th flange are bolted to connection.
Than prior art, the utility model is fixedly connected with respectively flange at the two ends of the splined shaft of hydrodynamic retarder, this flange is connected with flange on being fixedly installed on transmission shaft by bolt, thereby hydrodynamic retarder is arranged on the centre of two transmission shafts, stressed the passing on vehicle frame of a part, the load of balanced gearbox and back axle, easy for installation, and very little to the harm of gearbox and back axle.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with embodiment.
Referring to Fig. 1: the mounting structure of center-positioned hydraulic retarder, comprise splined shaft 1, rotor is fixedly mounted on splined shaft 1 and can rotates with splined shaft 1.Two ends at splined shaft 1 are fixedly connected with respectively flange 2, and splined shaft 1 is connected with the end of vehicular transmission shaft in the mode that flange connects.Flange 2 comprises the first flange, the second flange, three-flange and the 4th flange, the first flange and the second flange are fixedly connected on respectively the two ends of splined shaft 1, three-flange and the 4th flange are fixedly installed on respectively the end of two transmission shafts and the first flange and three-flange and are bolted to connection, and the second flange and the 4th flange are bolted to connection.
During installation, the flange with the flange at splined shaft two ends and end part of driving shaft is bolted respectively, seam is located by connecting and gets final product, and is easy for installation.
Need to prove at last, above embodiment is only in order to the technical solution of the utility model to be described but not the restriction technologies scheme, although the claimant has been described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or are equal to replacement, and do not break away from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present utility model.
