  • Patent number: 7124850
    Abstract: A four wheel drive assembly 10 including a torque transfer assembly 60 which operates under the control of the controller 62 and which receives and selectively transfers a certain desired amount of torque to a front axles 14, 15 and to the rear axles 14 17. The amount of transferred torque varies depending upon the occurrence of a sensed slip condition the use of a pre-emptive slip control mode of operation in which the controller 62 determines that it is likely that a slip may occur. Particularly, controller 62 is allowed to enter the preemptive mode of operation only after an actual slip has occurred and the controller 62 exits this preemptive mode of operation upon the occurrence of a certain event or condition or upon the passage of a certain amount of time.

  • Patent number: 7096994
    Abstract: The present invention relates to a method of controlling recovery in an electric power steering system which can enhance the recovery control function during recovery after steering when discriminating a recovery state using a steering angle and a steering angular velocity by determining whether or not the steering angular velocity is more than a predetermined value and carrying out recovery control only in the corresponding recovery state. The method of controlling recovery of the present invention comprises a first step of setting a recovery gain and a recovery pattern; a second step of obtaining a recovery current; a third step of determining whether the steering angular velocity is more than a predetermined value; and a fourth step of obtaining a motor driving current and performing the recovery control function by controlling the operation of the motor according to the obtained motor driving current.

  • Patent number: 7070019
    Abstract: An all terrain vehicle has a frame carried by a group of wheels. At least one of the wheels is steerably connected to the frame. A steering handle assembly is rotatably connected to the frame. A servo valve has an input shaft connected to the steering handle assembly and an output shaft connected to a pitman arm. A linkage extends from the pitman arm to the steerable wheel or wheels. A pump draws fluid from a reservoir and passes the fluid through the servo valve before the fluid is returned to the reservoir. The servo valve redirects at least a portion of the flow to a cylinder to drive a ram within the cylinder in response to steering movement of the steering handle assembly. The ram, in turn, provides a power assist to the steerable wheel or wheels. A variable speed, constant displacement pump can be used to vary the flow rate in a manner that reduces the flow rate as the vehicle speed increases. Alternatively, a bypass can be used to vary a flow rate through the servo valve.

  • Patent number: 7048294
    Abstract: A securing bolt device is inserted into a bore of a subassembly body. The device has a bolt and a spring element. The bolt has a shank which is insertable into the bore. A radial transverse bore extends through an end portion of the shank opposite to the insertable portion of the shank, and the shank has a blind bore in an axially directed end face. The spring element includes a loop, a first end of which is insertable into the transverse bore and a second end which is insertable into the end face bore. The loop forms a crossmember which extends across the shank of the bolt, and pressed against the bolt element by the spring force of the spring element. The locking device includes a subassembly body having a bore in which the bolt is axially movable. In a locked state a free end of the shank extends out of the bore and locks the securing bolt.

  • Patent number: 7048084
    Abstract: A CPU computes a throttle opening degree increasing speed V?h and a steering wheel angular velocity V? based on a throttle opening degree ?h and a steering wheel angle ?. Based on the throttle increasing speed V?h and the steering wheel angular velocity V?, the CPU selects one of a first drive mode and a second drive mode. The CPU controls the power transmission ratio of a power transmitting device according to the selected drive mode. Therefore, the power transmission ratio of the power transmitting device is properly controlled in accordance with the degree of intention for acceleration of the driver, which is computed based on the throttle increasing speed V?h, and the turning speed of the steering wheel, which is computed based on the steering wheel angular velocity V?. Therefore, the drive mode is properly switched in accordance with the driving state of a four-wheel drive vehicle.

  • Patent number: 7044490
    Abstract: Since a large part of an outer tube is made of light alloy such as aluminum, plating on a surface of the outer tube sometimes peels off. Thus, the surface of the outer tube is generally painted. However, a problem is presented in the external appearance of the outer tube due to painting. A structure of a front fork includes an outer tube into which an inner tube is movably inserted in an axial direction thereof. A stepped part is formed in the outer tube with a third elastic member fitted to the stepped part. A tube cover includes a lower portion which is supported by the third elastic member. Since an outer surface of the tube cover covering the outer tube is plated, the external appearance can be enhanced. Even if the outer tube has a rough surface, light metal castings or forgings can be used.
