Problems solved by technology

[0003] However, the application of the two units increases the cost and increases the volume of the transmission; the pressure required to press the friction plate is relatively high, generally around 5000N, if the pressure is small, it is easy to slip and cannot effectively transmit power, and the friction plate Easy to burn, in order to ensure the pressing force, it is bound to increase the volume, cost and energy loss of the shifting power source device

Abstract

A planetary gear transmission, including a housing, a planetary gear set, a brake assembly and a clutch assembly, the brake assembly includes a dual plate arranged between the housing and the planetary gear set, and a wedge block is provided on the rear side of the dual plate The front side of the assembly is provided with a driver push plate, and the rear side of the wedge block assembly is provided with a support piece. The shifting process of the present invention is smooth and has no power interruption; no traditional multi-disc friction discs are required during braking, and no one-way clutch is required, and the shift mechanism is small in size; the braking process does not require the force of pressing multi-disc friction pairs, which is harmful to the driver. The power requirement is low, which can greatly reduce the volume, cost and energy consumption of the braking unit power device.

Description

technical field [0001] The present invention relates to a planetary gear transmission, in particular to a planetary gear transmission using a wedge block shifting mechanism. Background technique [0002] In the field of traditional automobile planetary gear transmissions, the braking unit of the planetary gear transmission shifting actuator, the simultaneous use of multi-disc wet brakes and one-way overrunning clutches or the simultaneous use of band brakes and one-way overrunning clutches are widely used. The wet brake makes the power transmission smooth and soft, and has a long service life. The application of the one-way overrunning clutch effectively eliminates the shock of downshifting, shortens the shifting time, and reduces the energy loss. [0003] However, the application of the two units increases the cost and the volume of the transmission; the pressure required to compress the friction plates is relatively large, generally around 5000N. If the pressure is small, ...
