Differential mechanism and automobile transmission system with same
PendingCN113494583AAchieve power transmissionImprove battery lifeGear lubrication/coolingGearing controlGear wheelDriving mode
The invention discloses a differential mechanism and an automobile transmission system with the same. The differential mechanism comprises a shell and two planet gears located in the shell, and further comprises a planet carrier and a driven ring, the planet carrier and the driven ring are located in the shell, and the planet carrier and the driven ring are provided with meshing teeth matched with each other; and the driven ring is connected with the shell and can move relative to the shell to be close to or away from the planet carrier. The two planet gears are fixedly connected with the planet carrier through planet gear shafts; and the differential mechanism further comprises a driving unit, which is used for driving the driven ring to move close to the planet carrier so as to be meshed with the planet carrier or driving the driven ring to move away from the planet carrier so as to be separated from the planet carrier. The differential mechanism is a differential mechanism with a disengaging mechanism. When an automobile is switched from a four-wheel-drive mode to a two-wheel-drive mode, power of a power source is cut off through disengaging of the disengaging mechanism of the differential mechanism, such that only part of the structure of the differential mechanism needs to be driven when wheels rotate and are reversely dragged, rotational inertia is small, and energy consumption is low.

Punching device used for production of pipe molds
ActiveCN110340225AImprove connection strengthImprove connection stabilityShaping toolsHydraulic cylinderPunching
The invention discloses a punching device used for production of pipe molds. The punching device used for production of the pipe molds comprises a box. Two punching mechanisms and a mold positioning mechanism are arranged in the box. The two punching mechanisms are arranged horizontally and are connected through a connecting gear. The connecting gear is connected to the top of the box through a stand column. The mold positioning mechanism is connected to the inner side face of the box in a vertical moving mode through a guide rail. A hydraulic cylinder is arranged on the inner side face of thebox and is located above the guide rail. The hydraulic cylinder is connected with the mold positioning mechanism through a piston rod. The punching device is simple in structure and high in practicability; secondary punching formation of the pipe molds can be achieved, the punching process is simplified, and the punching formation efficiency is improved; and in addition, power transmission between the two punching mechanisms can be achieved, and when the punching mechanism on one side is started, the punching mechanism on the other side can be driven to work, so that continuous production ofthe pipe molds is ensured.

Oriented vibrating wheel system of driving gear box structure of road roller
ActiveCN104005320AReduce impact collision force and frictionExtend overall operating lifeRoads maintainenceOperating lifeBlock group
The invention belongs to the field of road roller equipment and particularly relates to an oriented vibrating wheel system of a driving gear box structure of a road roller. The oriented vibrating wheel system comprises a vibrating wheel, a rotating shaft, a forward eccentric block group and a reverse eccentric block group with the rotating direction opposite to that of the forward eccentric block group, wherein a direction-variable gear set is used for connecting the forward eccentric block group and the reverse eccentric block group, and changing the directions of the forward eccentric block group and the reverse eccentric block group and transferring power between the forward eccentric block group and the reverse eccentric block group; key joint fit with radial activity allowance is adopted between a power output shaft of the direction-variable gear set and a power output shaft of the forward eccentric block group, or between the power output shaft of the direction-variable gear set and a power input shaft of the reverse eccentric block group, or between the power output shaft of the direction-variable gear set and the power output shaft of the forward eccentric block group as well as the power output shaft of the direction-variable gear set and the power input shaft of the reverse eccentric block group. By using the oriented vibrating wheel system, the whole operating life of an inner gear can be effectively prolonged; in addition, influences of motion asynchrony, instant transmission impact and the like caused by small machining and assembling coaxiality errors of all parts and clearances among a plurality of layers of bearings are made up through one or more-layer key joint transmission.
