Abstract
The invention discloses a rear axle drive three-gear automatic variable transmission mechanism for an electromobile. A motor and a transmission gear are split. A front end cover of the motor is connected with a transmission gear body; a motor shaft is connected with a transmission shaft of a first transmission by a spline housing in the same plane; the first transmission drives a second transmission; the second transmission drives a gap bridge gear; the gap bridge gear drives a transmission gear; a hole is formed in the center of the transmission gear; a transmission shaft is tightly matched with a central hole of the transmission gear; and the transmission shaft is extended to two sides and then is connected with a rear axle by a spline. A gear shifting system performs three-gear automatic gear shifting and automatically changes the transmission proportions of the transmission mechanism according to the rotation speed of the motor. The conversion requirements of speed and moment of load climbing and plane travelling are met.
Description
Technical field
The present invention relates to electronlmobil, electric tricycle rearmost axle drives three shift automatic variable speed transmission devices, a kind of transmission device of rear-axle drive is in the different automatic conversion of third gear transmitting ratio of motor speed output height specifically.
Background technology
The environmental protection of electronlmobil, electro-tricycle, energy-saving and emission-reduction, be to realize transportation and energy's fundamental way that makes the transition, become the common strategic choice in countries in the world.The new stage that electronlmobil has entered China's development is subjected to the attention and the support of government very much! Electro-tricycle warp in the sixth of the twelve Earthly Branches is at China's general development.General all hub-types of the battery-driven car of domestic present use and the speed-changing mechanism that tooth is arranged, the big hill climbing ability of this product power consumption in use is limited, and speed and moment out of reach reasonably distribute conversion.The design's three shift automatic variable speeds just change the transmission device of transmission ratios automatically according to motor speed.
Summary of the invention
The object of the invention is in order to overcome the shortcoming of existing electronlmobil, electro-tricycle, and it is three shift automatic variable speed transmission devices of power that a kind of motor is provided.This scheme can just change transmission ratios by this speed-changing mechanism according to motor speed automatically under motor different rotating speeds situation, the speed of travelling in actv. solution load climbing and plane and the conversion demand of moment.
The technical scheme of battery-driven car rear-axle drive three shift automatic variable speed transmission devices of the present invention is: this mechanism is power with the motor, and motor shaft is connected with spline housing with main shaft 180 degree of first change-speed box, and one grade of speed-changing mechanism and second gear speed-changing mechanism are housed in first change-speed box.One grade of speed-changing mechanism and second gear speed-changing mechanism are just made automatic transmission ratio according to motor speed and are driven transmission gear, and transmission gear and the transmission gear of second change-speed box become 90 to spend and be connected.In second change-speed box three-gear gear shifting mechanism is housed, three-gear gear shifting mechanism is made the speed change reaction according to speed of transmission.Transmission gear by second change-speed box drives carrier gear, and the gap bridge tooth is connected with transmission gear 180 degree of second change-speed box, and the gap bridge tooth root can be set one or more compositions according to needs.The gap bridge tooth connects driving cog, driving cog central hole.Perforation can spline or polygonal hole making.Extension is connected with back axle to two limits for transmission shaft and driving cog centre hole close fit, transmission shaft.
Battery-driven car rear-axle drive three shift automatic variable speed transmission devices of the present invention, motor and change speed gear box divide body structure.The motor front end cover connects gearbox body, and motor shaft and the transmission shaft of first change-speed box become 180 to spend and be connected with spline housing, and speed change system is just made three shift automatic variable speeds, changed the transmission device of transmission ratios automatically according to motor speed.The speed of travelling in load climbing and plane and the conversion demand of moment have been solved.
