  • Patent number: 11499351
    Abstract: A striker mounting structure is designed to mount a striker on a vehicle body and prevent a door from entering a passenger compartment. A reinforcement provided on the vehicle body is covered by an outer panel. A striker mounting surface is arranged to be spaced away from the reinforcement in a front/backward direction of the vehicle body. The reinforcement is provided with an insertion hole opening toward a direction away from the passenger compartment. The striker and a reinforcement member are fixed to opposite sides of the striker mounting surface. A connecting rod is fixed to the reinforcement member and is formed with a locking portion extending into the insertion hole in a direction toward the passenger compartment and formed with an abutment portion. A distance between an end of the abutment portion and the passenger compartment is smaller than a distance between the striker and the passenger compartment.

  • Patent number: 11293163
    Abstract: A hydraulic drive apparatus includes a boom flow rate control valve, a target boom cylinder speed calculation part, a pressing force calculation part, a correction part, and a boom flow rate operation part. The target boom cylinder speed calculation part calculates a target boom cylinder speed for making the construction surface by the bucket closer to the target construction surface. The pressing force calculation part calculates the pressing force by which the bucket is pressed against the construction surface, based on the cylinder thrust of the boom cylinder and the center-of-gravity position information on the center-of-gravity position of the work device. The correction part corrects the target boom cylinder speed to make the deviation between the target pressing force and the calculated pressing force closer to 0. The boom flow rate operation part operates the boom flow rate control valve to provide the corrected target boom cylinder speed.

  • Publication number: 20210324604
    Abstract: In a blade control device, a blade operation control part outputs a command for raising and lowering a blade such that a position deviation between a blade position calculated by a blade position calculating part and a blade target position approaches zero in a case where a blade load is equal to or less than a second load threshold value, and outputs a command for raising the blade in a case where the blade load is greater than the second load threshold value. In a case where an update condition is satisfied, the update condition being set in advance so as to associate the blade load and a first load threshold value with each other, a target position setting part updates the blade target position using the blade position obtained when the update condition is satisfied as a reference.

  • Patent number: 10920757
    Abstract: A liquid pressure rotary machine in which a rotation delay of a retainer with respect to a cylinder block is reduced and contact of pistons placed between the retainer and the cylinder block with peripheral members is suppressed is provided. A piston pump includes a rotation shaft, a cylinder block, piston heads, piston rods, a retainer, a swash plate, and a tilt adjustment mechanism. When the tilt adjustment mechanism swings the swash plate, a discharge amount of the piston pump becomes variable. The retainer to be rotated together with the piston heads and the piston rods is supported by a retainer bushing provided in the rotation shaft. By engaging ball pins of the retainer bushing with spherical surface pin grooves of the retainer, the retainer and the retainer bushing are integrally rotatable about the center axis of the rotation shaft and the retainer is swung about the spherical surface center.
