Problems solved by technology

[0004] However, in order to simplify the structure and reduce the cost of the existing hybrid transmission system, when the hybrid transmission system is arranged, the engine cannot directly participate in the driving at low speeds, resulting in insufficient continuous power for mountain climbing.

Embodiment Construction

[0066] Next, the technical solutions in the embodiments of the present invention will be described in the following examples, and the described embodiments are merely, not all of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained without creative labor are not made in the premise of creative labor.

[0067] It should be noted that all directional instructions (such as above, lower, left, right, front, and post, ...) are only used in a particular attitude (as shown in the accompanying drawings). The relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication is also changed accordingly.

[0068] Further, in the present invention, "first", "second", and the like are intended to be intended to describe purposes only, and cannot be understood as an indication or implies its relative importance or implicitly indicated the number of technical features ind...

Abstract

The invention discloses a hybrid power speed control system and a vehicle. The hybrid power speed control system comprises an engine, a generator, a driving motor, a mandrel, a first input shaft, a second input shaft, a third input shaft, a first clutch, a second clutch, a plurality of synchronizers and a plurality of gear pairs. The engine is in transmission connection with the generator; the driving motor is in transmission connection with the second input shaft; the mandrel is sleeved with a first input shaft and a second input shaft. The first clutch is used for controlling connection or disconnection of the first input shaft and the generator; the second clutch is used for controlling connection or disconnection of the mandrel and the generator; power of the engine, the generator and the driving motor is transmitted to the wheels through the mandrel. According to the technical scheme, on the premise that the cost and the arrangement space are considered, the low-temperature adaptability of the vehicle, the mountain climbing continuous dynamic property and the full-working-condition economical efficiency of the vehicle are improved.

Description

Technical field [0001] The present invention relates to the field of vehicle technology, and more particularly to a hybrid power transmission system and a vehicle. Background technique [0002] With the proposal of carbon emissions, energy-saving and emission reduction in the vehicle industry will be an important work goal in the coming years. Due to the large carbon emissions of traditional fuel vehicles, new energy vehicles are increasingly concerned. [0003] Mixed vehicles can meet the battery life requirements while achieving energy saving and emission reduction, so that the hybrid system is currently the research and development focus in the future. [0004] However, the existing hybrid transmission system is for structural simplification, reducing cost, etc., causing the engine to participate directly in the drive at low speed when the mixed power transmission system is set, causing insufficient dynamic performance of mountain climbing. Inventive content [0005] The prim...
