Problems solved by technology

The currently used synchronizer will occupy a part of the axial space, making the axial size of the transmission larger, which will affect the layout of the engine and transmission, especially for cars with a transverse engine and front-wheel drive
If the number of gears is increased without increasing the number of transmission shafts, the axial dimension of the transmission will increase; if the number of gears is increased without increasing the number of transmission shafts, the radial dimension of the transmission will increase, which means Both results will increase the volume and weight of the transmission. Therefore, the number of gears in the transmission of the front-wheel-drive car with the transverse engine is not large, which makes the power and economy of the car unsatisfactory, and the smoothness of the transmission shift is poor.

Abstract

The invention discloses a built-in clutch which comprises a mounting shaft, gears, a splined hub, lifting levers and a bidirectional synchronization ring. The gears are sleeved on the mounting shaft, the splined hub is connected with the mounting shaft, cavities are arranged on the gears, inner joint gear rings are arranged on the side walls of the cavities, a hollow shaft sleeve is arranged in the mounting shaft, a slot is formed in the shaft sleeve, one end of each lifting lever is inlaid in the splined hub, the other end of each lifting lever penetrates the shot of the shaft sleeve and is inserted into an inner cavity of the shaft sleeve, an outer gear ring of the splined hub is matched with the inner joint gear rings of the gears, and the bidirectional synchronization ring is arranged among the splined hub and the side walls of the inner cavities of the gears. The built-in clutch has the advantages that the built-in clutch and a gear shifting control mechanism of the built-in clutch are based on an existing parallel shaft type gear transmission, so that gears of the transmission can be closely arranged, the axial size of the transmission can be reduced, the volume of the transmission can be decreased, the transmission can be lightened, and the manufacturing cost can be lowered.

Description

technical field [0001] The invention relates to the technical field of automobile transmissions, in particular to a novel synchronizer and a gear shifting mechanism of a parallel shaft transmission. Background technique [0002] An automotive parallel shaft transmission synchronizer is a device that engages or interrupts power between a gear or two gears. The currently used synchronizer will occupy a part of the axial space, making the axial size of the transmission larger, which affects the layout of the engine and transmission, especially for cars with the engine placed transversely and front-wheel drive. If the number of gears is increased without increasing the number of transmission shafts, the axial dimension of the transmission will increase; if the number of gears is increased without increasing the number of transmission shafts, the radial dimension of the transmission will increase, which means Both results will increase the volume and weight of the transmission. ...
