Abstract

The invention discloses a working wheel for a road building machine. A left plate, a center plate and a right plate are arranged in a working wheel barrel of the road building machine; a vibrating eccentric shaft is arranged at the center between the left plate and the center plate; two oscillating eccentric shafts are arranged on the two sides of the center; under different working condition requirements, the road building machine controls a magnetic exchange valve to switch two hydraulic pipelines of a hydraulic pump through an electric-control manipulation change-over switch; the vibrating eccentric shaft is driven by a motor; the two oscillating eccentric shafts are driven by another motor; and vibration compaction and oscillation compaction are conducted on a working surface by controlling the working wheel barrel. The working wheel has dual purposes and does not generate mutual interference; vibration and oscillation can be independent; the investment of equipment is reduced; and an application range is expanded.

Description

technical field [0001] The invention relates to a road construction machine, in particular to a road construction machine working wheel. Background technique [0002] At present, the commonly used working wheels of domestic road rollers mainly have the following structural forms: one is the pressure wheel of static rolling, which can be used as a driving wheel or a steering wheel, and it is compacted entirely by its own quality, and the operation efficiency is low. One is a vibrating wheel with an eccentric device on the central axis. The high-speed rotation of the eccentric shaft causes the vibrating wheel to generate non-directional vibration, so that the vibrating wheel body produces a centrifugal force in the circumferential direction, which has a deep impact on the subgrade and road surface and has a good compaction effect. The number of rolling times is small and the quality of the whole machine is small, but it also has the disadvantage that it is easy to cause damage...
