The application discloses a steering control method of a distributed drive vehicle, and relates to the technical field of vehicle steering control, and the method comprises the following steps: acquiring motion state information and road surface environment information of a target vehicle; determining a current adhesion coefficient of each wheel based on the motion state information and the road surface environment information; determining a target steering mode of the target vehicle and a center wheel corresponding to the target steering mode from a plurality of preset steering modes based on the current adhesion coefficient of each wheel, wherein the preset steering modes comprise a single center mode, a double center mode or a transition mode; and performing torque distribution control on each wheel based on the determined center wheel, so as to realize steering control of the target vehicle. The application realizes real-time dynamic adjustment of the steering mode and the center wheel, and effectively improves the steering stability and safety of the vehicle under complex road conditions.

Speed ​​reduction device (10) comprising the following: a case (31, 58), wherein a single centering collar connection surface (17, 17A, 17B) is provided in the housing (31, 58), wherein a component (54) of a front stage side of the speed reduction device (10) and a component (50, 15) of a rear stage side of the speed reduction device (10) are fitted onto the individual centering collar connecting surface (17, 17A, 17B) in a centering manner, and wherein the component (50, 15) of the rear stage side is a component of a connected machine (15) which is to be driven by the speed reduction device (10).

The utility model provides a single-center-distance multi-stage speed reducer, which belongs to the field of gear transmission, and comprises an input shaft, a middle shaft, an output shaft scheme, an input shaft, a first middle shaft, a second middle shaft, an output shaft scheme, an input shaft, a duplex gear, a differential mechanism, a middle shaft and an output shaft scheme, and the structures of all the schemes are located in the same shell. The axes of the input shaft and the output shaft coincide or are parallel. According to the speed reducer, a main body speed reducer transmission mechanism is formed through a center distance and a transmission combination of an input shaft, a middle shaft and an output shaft combination or an input shaft, a middle shaft, a middle shaft and an output shaft combination or an input shaft, a duplex gear, a middle shaft, an output shaft and a differential mechanism; each transmission shaft stretches across a complete supporting structure (without any cantilever support) of bearings at the two ends, the duplex gear, the output shaft and the differential mechanism are integrated into a coaxial concentric structure, a two-axle-distance multi-stage speed ratio structure is formed, the structure is compact, the space is saved, and the power density is large.

A pneumatic tire includes a pair of circumferential main grooves extending in a tire circumferential direction, and a pair of shoulder land portions and a single center land portion defined and formed by the circumferential main grooves. In addition, the center land portion includes a plurality of center narrow shallow grooves extending through the center land portion in a tire width direction. A groove depth H21 of the center narrow shallow groove is in a range 0.025≤H21 / Hg≤0.150 with respect to a maximum groove depth Hg of the circumferential main groove.

A reinforcement beam for a vehicle bumper system comprises a single sheet deformed to define first and second tubes sharing a common single center wall. A channel rib is formed on each tubes and a crevice rib over the center leg forms a third rib. Edges of the sheet are deformed to a radius so that their surface consistently engages an associated radiused corner formed on ends of the center leg, which facilitates consistent abutting line engagement of material surfaces, and thus facilitates consistent welding. In a preferred beam, front wall sections of each tube are coplanar and form a face of the beam, with each channel rib and crevice rib providing added stiffness to the beam, and yet nothing extends forward of the coplanar front wall sections. Related apparatus and methods are also disclosed.
