Disclosed are a dual-motor multi-gear hybrid transmission system and a vehicle. The dual-motor multi-gear hybrid transmission system includes an engine, a first motor, a second motor, a first clutch, a second clutch, a first planet row, a second planet row, a first input shaft, a second input shaft, a third input shaft and a brake assembly. The first input shaft is connected to the engine through the first clutch. The second input shaft is connected to the engine through the second clutch, and the second input shaft is sleeved outside the first input shaft. The first motor is connected to the engine. The second motor is connected to the first planet row through the third input shaft. The brake assembly is configured to brake the first planet row and/or the second planet row.

Dual-motor multi-gear hybrid transmission system and vehicle

Disclosed are a common control apparatus for parking and a clutch, an operating method thereof, and a vehicle. The common control apparatus for parking and a clutch comprises a parking mechanism, a clutch mechanism, and a motor; the parking mechanism comprises a positioning plate, a rotating drum connected to the positioning plate, a cam groove formed on the rotating drum, an elastic positioner, and positioning grooves; the positioning plate rotates under the driving of the motor; the elastic positioner interacts with the positioning grooves; the rotating drum can rotate to positions corresponding to parking lock, parking disengagement, clutch engagement, and clutch disengagement; the clutch mechanism comprises a clutch shifting fork assembly and a shifting fork driving cam; the cam groove comprises a straight groove and an engagement rotation groove; and when the shifting fork driving cam is located in the engagement rotation groove, the engagement rotation groove is engaged with the shifting fork driving cam to drive the clutch shifting fork assembly to move axially. The present invention simultaneously controls the disengagement and engagement of the parking mechanism and the clutch by means of one motor, and the apparatus has the advantages of simple structure, easy manufacturing, low cost, and high efficiency.

Common control apparatus for parking and clutch, operating method thereof, and vehicle

The present invention provides a power system for a hybrid vehicle, relating to the field of hybrid vehicles. The power system for a hybrid vehicle adopts a first planetary gear mechanism with two sun gears, the first sun gear rotates with an input shaft, the second sun gear and the input shaft are independent of each other, and the second sun gear achieves different motion states through a second brake or/and a second clutch, and cooperates with a first brake to provide different transmission ratios of four to six gears when an engine and motors are in driving, so that the power system is simple in structure and low in cost, and the fuel economy and acceleration dynamic performance of the power system are improved.

Power system for hybrid vehicles

A power system for a hybrid vehicle includes a first planetary gear mechanism and a second planetary gear mechanism that cooperate with each other, wherein a first sun gear rotates with a first input shaft, a second sun gear and the first input shaft are independent from each other, the second sun gear achieve different movement states through a first brake, a second brake and a second clutch, to provide different transmission ratios, so that the power system is simple in structure, low in cost and more flexible in adaptability. Further, a second electric motor is connected with the first input shaft through a third planetary gear mechanism, can reduce the speed of the second electric motor through the planetary gear mechanism, and increase the torque, to effectively reduce the size of the second electric motor or improve the acceleration performance of the vehicle.

Power system for hybrid vehicle

A hybrid transmission and a vehicle having the hybrid transmission. An engine, a generator, and a motor are coaxially arranged; a first planetary gear set is separately connected to a crankshaft of the engine and a rotor of the generator; a clutch comprises a first driving end connected to a planet carrier of the first planetary gear set and a second driving end connected to a ring gear of a second planetary gear set, wherein the first driving end and the second driving end are involved in engagement and disengagement; a rotor of the motor is connected to a sun gear axle of the second planetary gear set. When the motor performs driving, the clutch is disengaged from the engine and the generator to avoid a drag resistance of the engine.

A method for preparing a degradable magnesium-containing calcium phosphate-calcium sulfate porous composite biological scaffold by subjecting a calcined bovine cancellous bone mineral porous scaffold to a treatment using a ternary system containing a magnesium source, a sulfur source and a phosphorus source, taking out and drying, and subjecting to a high-temperature calcination. The degradable magnesium-containing calcium phosphate-calcium sulfate porous composite biological scaffold has good three-dimensional interconnected mesh structure, osteoconductivity, degradability, good mechanical strength and biocompatibility, simultaneously. At the same time, calcium sulfate whiskers with larger length-diameter ratio grow in the mesh, thereby increasing the specific surface area of the material and possibly improve the adhesion of cells. The composite biological scaffold may have potential osteoinductivity due to the effective addition of the osteogenic active ionized magnesium and the calcium sulfate which can produce a local high-calcium environment when degraded.
