Exhaust brake for exhaust manifolds and their exhaust gas collection pipes

The invention relates to an exhaust brake for Exhaust manifolds and their exhaust gas collection pipes, in the case of one the cross-section of the pipe, about an axis rotatable flap is provided.

The known flap engine brakes are usually arranged as an assembly by means of a flange connection between the exhaust manifold on the engine and in front of the exhaust pipe to the muffler, two such exhaust brakes being located on engines whose cylinders are arranged in a V-shape. Known motor brakes of this type are mounted in a cast housing, with a flange being fastened to each end of the pipe where the motor brake is installed, the

Motor brake is clamped between the two flanges with the help of tensioning screws.

Exhaust brakes have the advantage of using the engine as braking power to use and to relieve the hydraulic-mechanical brakes, but they have the disadvantage that they are in such an unfavorable place in the vehicle due to their weight and for vibration-related reasons come to rest that in the case of a necessary test or repair of the exhaust brake only a whole series has to be removed from parts before the latter can be reached. Each of the two exhaust brakes in the V-engine is attached with three / four screws and two lens seals between two three-hole / four-hole flanges. The components are, as they are under the vehicle, by water, in winter by road salt, dirt and mud and the like, as well as by corrosion phenomena heavily used, with the nuts for loosening the Flange connections are so tight that the fastening screws can usually only be loosened by sawing off.

The present invention addresses the problem of this Avoid disadvantages by having an outwardly closed socket and for mounting the valve axis on the outside of the pipe opposite a sleeve are applied, wherein in the Sleeve a bearing bush is used.

According to a proposal of the invention, the procedure is that the exhaust brake preferably behind the last exhaust port and is arranged in front of the open end of the exhaust manifold.

The design according to the invention avoids the disadvantages the known engine brakes, in that a number of parts can be saved, with the addition of that the assembly costs for installation and removal and the cost of spare parts can be reduced significantly.

Another significant advantage is that the exhaust brake according to the invention at any desired Place of the exhaust pipe can be installed, since a splash or other connection is avoided and thus vibration-related problems do not have to be taken into account.

Further features of the invention emerge from the following description of an embodiment in connection with the drawing and the claims,

It show, in schematic sketches,

Figure 1 shows a cross section through the in

Exhaust pipe built-in exhaust brake according to the invention and

FIG. 2 is a side view of FIG. 1.

The exhaust brake is installed in an exhaust gas collecting pipe 1, the flap axis 2 running transversely to the exhaust bore and at its one outer end 3, for example, is provided with a square for attaching an actuating lever. The damper 2 has within the exhaust bore Λθϊηθ Cylind ris cheTWe eTlmf li ^r, i e d in th e ,, k flap is attachable. To support the flap axis 2 is used

on the one hand a bushing 5 which is closed to the outside and which is fastened on the pipe 1 and on the other hand an opposite one Sleeve 6. A bearing bush 7 is pushed into the sleeve 6, which with the help of a Seger ring 8 is secured.

The exhaust brake according to the invention is installed in such a way that bores are first drilled in the pipe 1 transversely to the exhaust bore. Subsequently, the ^ closed socket 5 and the sleeve 6 and the bearing bush 7 are attached to the Seger ring 8, whereupon the flap h is inserted through the exhaust gas collecting pipe 1 and the flap axis 2 is inserted, which with the help of an ijo.der._meJire -_- : 'rer "pens ~ fo"' is backed up.
