Abstract

The accessible mounting space for components in vehicles is many times very restricted. The object of the present invention is to provide a silencer, which is possible to mount in the space between a tractor and a trailer in a vehicle combination. According to the invention, the silencer is elongated and it has a relatively restricted cross section area. The silencer mounts in a substantially vertical position on the tractor in the space between the tractor and the trailer. The silencer has an external surface having a shape adapted to the positions of front wall surface of the trailer during turning motions between the tractor and the trailer. Thereby, it is possible to mount the silencer such that it does not get in contact with the front wall surface of the trailer during said turning motions. The conventional mounting space for the silencer in the vehicle may now be used by other components.

A silencer for a tractor-trailer combination

The accessible mounting space for components in vehicles is many times very restricted. However, the space between a tractor and a trailer in vehicle combinations is not usually used as a mounting space for components. That depends on the turning motions between the trailer and the tractor, which reduces the accessible mounting space considerably. 

The object of the present invention is to provide a silencer, which is possible to mount in this space. According to the invention, the silencer is elongated and it has a relatively restricted cross section area. The silencer mounts in a substantially vertical position on the tractor in the space between the tractor and the trailer.  The silencer has an external surface having a shape adapted to the positions of the front wall surface of the trailer during said turning motions. Consequently, by using a silencer having a suitable mounting position in this space and a suitable design, the silencer does not get in contact with the front wall surface of the trailer during said turning motion. When the silencer has been mounted in this space, the conventional mounting space for the silencer in the vehicle may now be used by other components.

Fig. 1 and 2 show an embodiment of the invention. In this case, the vehicle combination consists of a truck 1 and a semitrailer 2. An elongated silencer 3 is mounted in a vertical position on a frame of the truck 1 in the space between the truck 1 and the semitrailer 2. The silencer 3 is a part of an exhaust gas system of the truck 1.  The silencer 3 has a lower portion 3a having a substantially circular circumference and an upper part 3b having a substantially triangu...
