Description
15 20 25 30 which is braked via a brake and can be fixed with respect to a housing. The brake is supposed to improve the generation of no-load losses in the permanent brake configured as a hydrodynamic retarder. However, the provision of an additional brake rnakes the permanent brake more expensive, increases the installation space required and makes its use more complicated.
Proceeding from this prior art, the object on which the present invention is based is to improve a permanent that the efficiency of the increase the brake device such in rotational speed in step~up stage can be increased with simple means.
The object is achieved by a permanent brake device with the features of Claim l. Configurations of the solution are the subject matter of subordinate claims.
In the case of a permanent brake device for a motor vehicle, the rotational speed of an output shaft of the motor vehicle is stepped up by a step~up stage. The step-up stage comprises a planetary transmission with internal gear, sun gear and at least one planetary gear. According to the invention, the planetary gears, or the at least one provided planetary gear, are mounted rotatably on a planetary Carrier which is permanently fixed in a housing. The arrangement of the planetary gears on a planetary carrier fixed on the housing enables, alongside a small space requirement, a significantly higher rotational speed with which the parts of the permanent brake device which achieve the braking action can be driven. The axial distance between output shaft and rotor shaft remains uninfluenced and the braking power which can be achieved can he maintained.
In one advantageous configuration of the invention, a rotating component of the permanent brake device is LH 10 15 20 25 30 connected or can be connected in a rotationally conjoint manner to the sun gear. A particularly efficient increase in rotational speed can be achieved by the transmission of the rotational speed of the output shaft of the vehicle transmission via the planetary gears to the sun gear.
In one particularly advantageous formation, the internal gear is rotatably mounted in the housing of' the permanent brake device in a mounting device. As a result, the mounting device serves the purpose of secure guidance of the internal gear. An axial movement of the internal gear which arises, for example, from the toothing can be effectively avoided as a result.
In one advantageous design, the internal gear of the invention has an external toothing which is in engagement with a toothing of a gearwheel which is connected or can be connected to the output shaft of the motor vehicle. As a which is fastened on the output shaft or result, a gearwheel with spur gear toothing, can be shifted with the output shaft into a torque~ transmitting connection, can directly and in a simple structure engage in the external toothing of the internal gear and drive said internal gear.
In one advantageous design, the rotating component, which is driven by the step~up stage according to the invention, of the permanent brake device is the rotor of the hydrodynamic retarder. In this manner, the rotational speed of the rotor of the hydrodynamic retarder is increased in comparison to the driving rotational speed of the output shaft which rotates as a function of the vehicle speed to a significantly higher rotational speed level. The' braking action of the hydrodynamic retarder is thus significantly amplified and is also still effective in the case of lower vehicle speeds. 10 15 20 25 30 35 In a different design, the rotating component is the rotor of an electrodynamic retarder. advantageous An amplified braking action can also be achieved here as a result of the increase in rotational speed.
In addition to hydrodynamic and electrodynamic brake components of hydrostatic brake shifted to a devices, rotating devices can also be higher rotational speed and the brake devices can thus be improved in terms of their braking power. Combinations of various brake devices with corresponding advantages are also conceivable.
The invention is described in greater detail on the basis of a drawing.
In the drawing: Fig. 1 shows an arrangement of a step-up stage according to the prior art Fig. 2 shows a step-up stage according to the invention Fig. 3 shows a first permanent brake device Fig. 4 shows a second permanent brake device Fig. 1 shows a shift transmission 2 with a transmission input shaft 4 and an output shaft 6. Transmission input connected via a friction clutch 8 to an the shift shaft 4 is internal combustion engine 10 which drives transmission.
A gearwheel 12 is arranged fixedly on output shaft 6 of shift transmission 2, which qearwheel 12 rotates with the rotational speed of output shaft 6. A gearwheel 14 on a rotor shaft 16, which is connected to a permanent 10 15 20 25 30 35 brake device 18, with gearwheel 12. The transmission cogs ratio of the rotational speed of output shaft 6 in relation to rotor shaft 16 is determined by the toothing ratio of both gearwheels 12 and 14 which form a step~up stage 20. The diameter of gearwheel 12 is larger than the diameter of gearwheel 14 in order to achieve a step-up of the output shaft rotational speed.
Fig. 2 shows a step-up stage 22 according to the Fig. 2 also shows a shift transmission 2 with a transmission input shaft 4 and an output shaft invention. 6. Transmission input shaft 4 is again connected via a friction clutch 8 to an internal combustion engine 10 which drives the shift transmission.
Here too, a gearwheel 24 is arranged fixedly on output shaft 6 of shift transmission 2, which gearwheel 24 rotates with the rotational speed of output shaft 6. A gearwheel is fixedly arranged as a sun gear 26 on a rotor shaft 16 which is connected to a permanent brake device 18. Sun gear 26 is part of a planetary transmission 28. In planetary transmission 28, the sun gear cogs with planetary gears 30 of which one planetary gear is shown here. Planetary gears 30 also cog with an internal gear 32 which has an internal toothing and an external toothing. The internal toothing engages as described in the toothing of planetary gears 30, while the external toothing engages in the spur gear toothing provided on gearwheel 24.
In the arrangement shown in Fig. 2, internal gear 32 is mounted in a mounting device 34. However, the internal gear can also only be formed as a ring which is arranged between gearwheel 24 and planetary gears 30.
According to the invention, planetary gears 30 are arranged on a planetary carrier 36 which is connected fixedly to transmission housing 38 of shift 10 15 20 transmission 2. Planetary gears 30 thus rotate on planetary Carrier 36, but are otherwise provided in a stationary fashion in transmission housing 38.
