A rack-and-pinion gear is described, which is suitable in particular for a steering system of a motor vehicle. In this a pinion is supported in a pinion housing and meshes with a rack inside this pinion housing. The rack here projects from the pinion housing through at least one housing aperture. A stop ring, which serves to limit a rack longitudinal movement and/or a tilting of the rack, is moreover held in the housing aperture by means of a press fit. In addition, a steering gear having such a rack-and-pinion gear and a steering system for a motor vehicle comprising such a steering gear are described.

Described herein are systems and methods providing a slip gear for an industrial cart. One embodiment includes a slip gear that includes a track gear for engaging with the track, a stabilizing bar, and a motor gear for engaging with a drive motor and the track gear. The slip gear may also include a stabilizing bar that is rotatably coupled to the track gear and the motor gear. In some embodiments, when the drive motor rotates the motor shaft, the motor gear rotates with the motor shaft to cause rotation of the track gear to propel the industrial cart. In response to an object pushing the industrial cart along the track, the stabilizing bar rotates to disengage the track gear from the track, thereby reducing friction between the industrial cart and the track.

A torque transmission device has a pinion that includes a plurality of rollers that mesh with a plurality of teeth of an output. Each roller is supported by a bearing having rotating bearing elements. A clearance compensation for the diametrical difference between a diameter of each roller and an inscribed diameter of the associated rotating bearing elements is included in the plurality of teeth of the output such that there is no interference between the plurality of rollers and the plurality of teeth.

A rack biasing device includes a rack guide configured to guide movement of a rack shaft, a cylindrical guide member attached to a rack housing, an annular first sealing member configured to provide a seal between the guide member and the rack guide, a biasing member disposed on one side of the rack guide opposite to the rack shaft, an engaging member configured to cause the biasing member to generate biasing force to push the rack shaft toward a pinion shaft, and a second sealing member configured to provide a seal between the guide member and the rack guide, and abut against the engaging member. The rack guide has an annular distributing portion in an end portion that faces the engaging member.

An automated sliding panel mechanism is disclosed. An automated sliding panel mechanism includes a motor attached to a first component of a sliding panel that is configured to move the sliding panel between a closed position and an open position. The mechanism also includes a power source and a rack attached to a second component of the sliding panel and including a base with rack teeth extending from a plane thereof. A gear is rotated by the motor and has gear teeth shaped to mesh with the rack teeth. A manual release mechanism is adapted to move the gear along its axis of rotation, from an engaged position, wherein the gear teeth mesh with the rack teeth to a released position, wherein the gear teeth are disengaged from the rack teeth. The manual release mechanism also includes a holding mechanism adapted to hold the gear in the engaged position and in the released position as selected by a user.

The disclosure provides a steering system for a vehicle. The steering system includes a wheel having an inner surface and an outer surface, and a tire mounted thereon. The steering system includes a wheel support including an upper arm and a lower arm that rotatably support the wheel. At least one of the upper arm and the lower arm includes a curved member positioned to contact the inner surface of the wheel when the wheel is at a maximum steering angle. The steering system includes a steering rack and a tie rod coupled between the steering rack and the wheel support. The steering system also includes a compressible stopper coupled between the tie rod and the steering rack. The stopper is configured to compress as the wheel is turned toward the maximum steering angle and when the tie rod is moved past the maximum steering angle.

A reciprocating linear/rotational motion conversion device has a main shaft, a linear motion guiding mechanism, a sector gear and a rack frame. The sector gear is fixedly connected with the main shaft. A rack pair is arranged on the inner wall of the rack frame. The rack pair comprises a first gear rack and a second gear rack separately arranged on both sides of the sector gear. The reciprocating linear/rotational motion conversion device further includes a reversing mechanism fixedly connected with the main shaft. A cylinder device contains the reciprocating linear/rotational motion conversion device, connecting rods, pistons and cylinder bodies. The cylinder body is sleeved on the piston, and a cylinder head is arranged on one end of the cylinder body.

In one version there is provided a shaft locking assembly for use in an apparatus, to provide motion control and unwanted movement elimination of the apparatus. The shaft locking assembly includes a locking device with a locking shaft having a castellated ring element with castellations. The shaft locking assembly includes a drive shaft and a rotating element disposed around the drive shaft. The shaft locking assembly includes a retaining structure assembly having a side portion with projection members corresponding to the castellations. The shaft locking assembly is in a locked position when the castellations are engaged and interlocked with the projection members, and the shaft locking assembly is in an unlocked position when a shaft engagement device is engaged with the drive shaft and the locking shaft, and actuates the locking shaft, so that the castellations are disengaged and unlocked from the projection members, and rotates the drive shaft.

One embodiment of the present invention provides an actuator comprising: a housing having a mounting space part formed therein; a motor part provided inside the housing and generating power; a reduction gear part of which a plurality of gears respectively having an internal gear and an external gear sequentially engage with each other so as to transmit the power generated in the motor part; and a rod part engaging with the gear disposed at the last position, and linearly moving according to the rotation of the gear, wherein one of the plurality of gears is formed such that the internal gear and the external gear can rotate together or rotate independently.

A pinion (1) including a pin gear allows easy engagement with or disengagement from a mating gear. The pinion (1) includes a plurality of pins (2) as teeth, and includes a first plate (4) and a second plate (5) described below. The first plate (4) interconnects first ends of the pins (2). The second plate (5) is spaced from the first plate (4) in the rotation axis direction of the pinion (1), and interconnects second ends of the pins (2). The second plate (5) has, on its outer peripheral edge, recesses (15, 16) each between two pins (2) adjacent circumferentially. The recesses (15, 16) recede inward from inner circumferential ends of the pins (2). The pinion (1) is moved axially for engagement with or disengagement from the rack (3). The pinion (1) increases flexibility at the time of engagement with or disengagement from a mating gear.
