Abstract

The invention relates to a screed arrangement (100, 100') for a paver. The screed assembly (100) includes: a screed body (101) including a deflector member (102) and a soleplate; and an oscillating tamper bar assembly (104) positioned at between the deflector member (102) and the base plate (106). The screed arrangement also includes a connecting element (108) connecting the oscillating tamper bar arrangement and the screed body to each other.

Description

technical field [0001] The present invention relates to a screed arrangement for a paver machine. The invention also relates to a corresponding paver comprising such a screed arrangement. Accordingly, the invention is applicable to a work machine in the form of a paver arranged to distribute paving material onto the ground. Background technique [0002] In the past, heavy vehicles in the form of pavers have been used to distribute paving material onto road surfaces. In particular, pavers are used when laying eg asphalt or concrete on roads, bridges and the like. Thus, the pavers deliver the asphalt / concrete onto the ground. From this, the paver performs the distribution of asphalt / concrete as well as the initial compaction of the material. Afterwards, roadrollers preferably perform final compaction of the asphalt / concrete material. [0003] With regard to pavers, a common technique for distribution and initial compaction is to use a so-called screed unit located at the ...
