The present invention relates to an arrangement for an elevation device of a vehicle mounted weapon system. The weapon system comprise a weapon and a feeding chute. Said elevation device is arranged to allow elevation movement of the weapon about an elevation axis. Said elevation is performed in connection to sides of said elevation device about said elevation axis. Said feeding chute is configured to be arranged in connection to one side. Said arrangement comprises an arc-shaped sector bearing device of a bearing configuration for facilitating said elevation. Said bearing device is arranged in connection to a front portion at said one side at a radial distance from said elevation axis so as to provide space for said feeding chute on said one side in connection to said elevation axis. The invention also relates to a vehicle with an arrangement according to the present invention.

Arrangement of an elevation device for a vehicle mounted weapon system

Disclosed is an arrangement for feeding ammunition to a weapon. The weapon is mounted to an elevation device arranged to allow elevation movement of the weapon about an elevation axis. The arrangement includes a feeding chute connected at one end to the weapon. The feeding chute includes a set of elements assembled together in a stacked configuration. The set of elements is arranged about a shaft configured to be concentrically arranged relative to the elevation axis so as to allow movement of individual elements of the set of elements about the shaft in connection to elevation movement of the weapon about the elevation axis. The invention also relates to a vehicle with an arrangement according to the present invention.

Device for manoeuvring a tension wheel in a chassis of a tracked vehicle, in which the tension wheel is rotatably mounted on a telescopic rocker arm (). The rocker arm can, on the one hand, be lengthened and shortened by a first hydraulic cylinder and, on the other hand, swivelled about a transverse axis () by a second hydraulic cylinder for the purpose of raising and lowering the tension wheel. The first hydraulic cylinder is designed to act upon a lever arm () of a sleeve () rotatable in a hub part () of an inner part () of the rocker arm (), which sleeve has an eccentrically mounted crank pin () which is hinge-connected to an outer part () of the rocker arm for the purpose of displacing the latter relative to the inner arm part, in the event of a mutual rotation motion between the sleeve () and the hub part () of the inner rocker arm part, in such a way that the rocker arm is lengthened upon a downward swivel motion of the arm and the tension wheel.

An apparatus ( ) for discharging shells from a magazine. The apparatus comprises a first ramming element ( ) for initial, primary linear discharge of a shell (G) from the magazine, and a second ramming element ( ) for continued, secondary feed of the shell (G) to an advanced position while the return movement of the first ramming element ( ) is effected.
