Problems solved by technology

The traditional wheel reducer is only a single-stage reducer. Although this reducer can reduce the speed and increase the torque, the application environment of electric heavy trucks is even harsher, so the existing reducer cannot meet the needs of different working conditions. Switching between high and low gears, the transmission efficiency is low, and the load on the motor is heavy

Embodiment Construction

[0011] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0012] like figure 1 As shown, a two-speed reducer transmission mechanism matching planetary gear reduction in the present invention includes a wheel-side reducer, a bevel gear differential and a two-speed transmission. The two wheel reducers are coaxially installed with the bevel gear differential, and the two wheel reducers are respectively located at both ends of the bevel gear differential; the helical gear 19 in the bevel gear differential is connected to the gear in the two-speed transmission Shaft 14 engages.

[0013] The wheel reducer is a planetary reduction mechanism, and the planetary reduction mechanism includes sun gear 1, planetary gear 2, ring gear 3, pin shaft 4, planet carrier 5, ring gear bracket 6, bell hub 7, wheel hub 8 and sun gear shaft sleeve 9. Five planetary gears 2 mesh with the sun gear 1 and the ring ge...

Abstract

The invention relates to a two-gear reduction gear transmission mechanism matched with planetary speed reduction. The transmission mechanism comprises two hub reduction gears, a bevel gear differential mechanism and a two-gear transmission. The two hub reduction gears and the bevel gear differential mechanism are coaxially installed, and the two hub reduction gears are located at the two ends of the bevel gear differential mechanism respectively. A bevel gear (19) in the bevel gear differential mechanism is meshed with a gear shaft (14) in the two-gear transmission. The transmission efficiency is improved, and the load of a motor is reduced.

Description

technical field [0001] The invention belongs to the technical field of multi-gear drive axles for electric heavy trucks, and in particular relates to a transmission mechanism of a two-speed reducer matching planetary reduction. Background technique [0002] With the increasingly prominent trend of electrification, the application of wheel-side motor drive axles in electric buses has gradually matured. However, there are still certain technical bottlenecks in the motor drive axles suitable for heavy-duty trucks. Among them, the wheel-side reducer is the key to realize electric heavy-duty truck drive axles. One of the core components of high torque, it plays the role of deceleration and torque increase. The traditional wheel reducer is only a single-stage reducer. Although this reducer can reduce the speed and increase the torque, the environment of the electric heavy truck application is even harsher, so the existing reducer cannot meet the needs of different working conditio...
