Problems solved by technology

But, the continuously variable transmission in the related art, because its pulley is made up of two discs, and the groove in the middle of two discs forms V-shape, utilizes hydraulic control mechanism to push one of discs to move, thereby changes V-shaped groove. The width of the groove, the hydraulic pressure will have a certain hysteresis during the movement of the driven wheel, and it will not be able to achieve the speed change in time

Embodiment Construction

[0019] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0020] An oil-electric hybrid continuously variable transmission device, comprising a transmission mechanism 10 connected to an engine; a transmission mechanism 9 connected to an actuator, the transmission mechanism 9 and the transmission mechanism 10 are meshed through gears, and the transmission mechanism 10 includes A belt pulley with adjustable wheel groove size is installed on the driving wheel shaft 105 and the pulley shaft 104. , the output end of the driving wheel 101 is installed with a generator 106 and a motor 107 in sequence. In the present invention, by setting the combined pulley, the pulley can change the size of the pulley groove at different rotating speeds, and change the transmission ratio between the two pulleys to realize the purpose of adjusting the rotating speed of the output shaft.

Abstract

The invention provides an oil-electric hybrid continuously variable transmission device which comprises a speed change mechanism connected with an engine, and a transmission mechanism connected with an execution mechanism; the transmission mechanism is engaged with the speed change mechanism through gears, and the speed change mechanism comprises a drive sprocket axle and a belt axle; and belt pulleys with wheel grooves adjustable in size are mounted on the drive sprocket axle and the belt axle correspondingly. A generator and a motor are sequentially mounted at the output end of a drive wheel. According to the oil-electric hybrid continuously variable transmission device, the output speed is adjusted by adjusting the sizes of the belt pulleys, the purpose of continuously variable transmission is achieved, clamping stagnation of a vehicle in the speed changing process is avoided, and speed changing is smooth and steady; and the motor is directly connected with the drive sprocket axle, so that oil-electric hybrid power of the vehicle can be achieved through motor driving.

Description

technical field [0001] The invention relates to an oil-electric hybrid continuously variable transmission device. Background technique [0002] Continuously variable transmission, which uses the drive belt and the variable working diameter of the main and driven wheels to transmit power, can realize the continuous change of the transmission ratio, so as to obtain the best match between the transmission system and the engine working conditions. The continuously variable transmission in the related art includes two pulleys and a metal belt, and the metal belt is sleeved on the two pulleys. Pulley 4 consists of two discs. The grooves in the middle of the two discs form a V shape. One of the discs is controlled by a hydraulic control mechanism. Depending on the engine speed, it can be separated and pulled together. V-shaped The groove also widens or narrows accordingly, raising or lowering the metal belt, thus changing the diameter of the metal belt in contact with the pulley. ...
