Publication number: 20110098885Abstract: A suspension system for a traveling vehicle body is disclosed. The system includes a suspension reference position varying mechanism (18) for varying a reference position of a suspension stroke of the suspension mechanism (100), and a controller (35) configured to calculate an intermediate value from a maximal value corresponding to the maximal position of the suspension stroke and a minimal value corresponding to the minimal position of the suspension stroke, and to control the suspension reference position varying mechanism such that, when the calculated intermediate values deviates from a set target range, the intermediate value is displaced toward the target range. The controller (35) increases a control execution frequency for the suspension reference position varying mechanism (18) when the traveling speed of the vehicle body is low, and reduces the control execution frequency for the suspension reference position varying mechanism (18) when the traveling speed of the vehicle body is high.Type: ApplicationFiled: March 25, 2009Publication date: April 28, 2011Applicant: KUBOTA CORPORATIONInventors: Kenichi Iwami, Shigeki Hayashi, Akihiro Matsuzaki, Toshimitsu Yazaki, Atsushi Hayashi, Kazuma Ishihara

Patent number: 7918470Abstract: A hydraulic suspension system includes a suspension base (16) supporting wheels, a hydraulic cylinder (19) for displaceably suspending the suspension base from a vehicle body, and an oil passage connected to the hydraulic cylinder. An accumulator (21, 23) is incorporated within the oil passage. A flow control valve (51) is incorporated at an oil passage portion between the hydraulic cylinder and said accumulator for controlling an amount of work oil flowing therebetween. A pressure sensor (56) is provided for detecting a cylinder oil passage pressure effective on the hydraulic cylinder. A control unit (57) is provided for controlling operation of the flow control valve, based upon a detection value from the pressure sensor.Type: GrantFiled: February 18, 2009Date of Patent: April 5, 2011Assignee: Kubota CorporationInventors: Akihiro Matsuzaki, Atsushi Hayashi, Toshimitsu Yazaki, Kenichi Iwami

Patent number: 7845652Abstract: An arrangement is provided in which the durability of an operation changing means is improved when this means is provided to the suspension mechanism in a suspension structure for a work vehicle. A maximum position (A1) and minimum position (A2) of the operation of the suspension mechanism are detected, and an intermediate position (B1) between the maximum and minimum positions (A1) and (A2) is detected. When the intermediate position (B1) departs from the target range (H1), the operation of the suspension mechanism is changed to the body raising side or body lowering side so that the intermediate position (B1) moves toward the target range (H1).Type: GrantFiled: April 3, 2008Date of Patent: December 7, 2010Assignee: Kubota CorporationInventors: Kenichi Iwami, Shigeki Hayashi, Yoshihiro Ueda

Publication number: 20100168959Abstract: The hydraulic suspension system comprises a suspension mechanism (100) for a traveling vehicle body, a suspension reference position variation mechanism (18) for varying a reference position of a suspension stroke of the suspension mechanism, and a stopped state detector (58) for detecting a state in which operation of the suspension mechanism (100) has stopped. The control management unit (60) controls the suspension reference position variation mechanism (18) so that when operation of the suspension mechanism (100) is detected by the stopped state detector (58) to be in a stopped state, the operation of the suspension mechanism (100) moves toward a target range, in preference to control based on a suspension stroke position obtained from a suspension stroke position sensor (37).Type: ApplicationFiled: September 17, 2009Publication date: July 1, 2010Applicant: KUBOTA CORPORATIONInventors: Kenichi Iwami, Shigeki Hayashi, Atsushi Hayashi, Akihiro Matsuzaki, Toshimitsu Yazaki, Nobuyuki Okabe
