Title:
作業機械の緩み調整装置を有する駆動履帯チェーン張力調整用履帯張力調整組立体
Document Type and Number:
Japanese Patent JP4676059
Kind Code:
B2
Abstract:
An undercarriage assembly of a work machine includes a first drive track chain and a second drive track chain. The undercarriage assembly also includes a first hydraulic actuator mechanically coupled to the first drive track chain so as to adjust tension on the first drive track chain and a second hydraulic actuator mechanically coupled to the second drive track chain so as to adjust tension on the second drive track chain. The undercarriage assembly further includes a slack adjuster assembly. The slack adjuster assembly has (i) an adjuster housing defining (a) a main chamber, (b) a fluid inlet, (c) a first fluid outlet which is fluidly coupled to the first hydraulic actuator, and (d) a second fluid outlet which is fluidly coupled to the second hydraulic actuator, (ii) a first piston positioned in the main chamber, the first piston selectively couples the fluid inlet to the first fluid outlet, and (iii) a second piston positioned in the main chamber, the second piston selectively couples the fluid inlet to the second fluid outlet. Movement of the first piston from a first decreased-tension position to a first increased-tension position causes actuation of the first actuator so as to increase tension on the first drive track chain. Movement of the second piston from a second decreased-tension position to a second increased-tension position causes actuation of the second actuator so as to increase tension on the second drive track chain.
