Title: Street sweeping machine attached to the front of a vehicle
Inventor: GRUEBLER WALTER DIPL ING
IPC: E01H1/05
Filed: 1981-03-02
Abstract: The invention relates to a street sweeping machine attached to the front of a vehicle and having a rotating brush roller which can be adjusted within a predetermined range about a vertical axis, at an angle to the direction of travel, which is supported at both ends in a cowling and is driven via a roller cardan shaft situated above the cowling and extending approximately parallel to the vertex of the latter, together with its gear reducer unit, the machine also having an angular gear unit provided at the upper vertex of the cowling in the central cross-sectional plane of the latter, the output shaft journal of which is connected to the roller cardan shaft, while an input-shaft journal extending approximately along the axis of the front part of the vehicle is connected via a universally-jointed power take-off shaft to a power take-off gear unit on the vehicle. In this machine, the cowling is suspended on the angular gear unit, which is attached in a fixed manner to the front of the vehicle, in a manner which allows adjustment about a vertical axis of adjustment, the angular gear unit, for its part, is mounted on a full-floating shaft extending parallel to the longitudinal axis of the front part of the vehicle and is preloaded into a horizontal position by a torsion bar, and the roller cardan shaft is of telescopic design. By means of the suspension of the cowling from the angular gear unit, it is possible to ensure without difficulty that the vertical axis about which the brush roller can be adjusted runs exactly through the upper vertex of the cowling. By means of the special mounting of the angular gear unit on a supporting frame of the supporting vehicle by means of a torsion bar, it is possible to ensure that the axis of the brush roller can adapt without difficulty to the respective camber of the road while, on the other hand, in plan view, the distance of the angular gear unit from the front edge of the supporting vehicle is constant in all operating positions. This allows the angular gear unit to be driven without any difficulty whatsoever via a universally jointed power take-off shaft by a power take-off gear unit of the supporting vehicle. The telescopic cardan shaft which, starting from the angular gear unit, drives the brush roller via the gear reducer unit is a commercially available component and does not require a special design. Overall, the invention provides a street sweeping machine for attachment to the front of a vehicle which can be driven via a power take-off gear unit on the supporting vehicle with a low load torque about the transverse axis of the vehicle and an equal clearing width in relation to the longitudinal axis of the supporting vehicle. <IMAGE>
