Abstract
A structure of a power-driven system of a full-electric light bus relates to the structure of the power-driven system of an electric vehicle. A drive motor (4) in the power-driven system is laid on a frame behind a rear axle of the bus, an output shaft of the drive motor is directly connected or connected with a transmission shaft (3) through a variable/speed reducer, and the transmission shaft drives a rear wheel (2) through the rear axle; and both a battery box and an accessory system are distributed in a space cabin (1) which is formed by a framework and is positioned between the front and the rear axles of the whole bus. The structure adopts the postposed rear wheel of the drive motor to drive, so the drive motor approaches the rear wheel, and drives the adjacent part, accordingly, the structure is compact, a transmission line is short, and the transmission efficiency is benefited to being improved; and an integral frame crossbeam between the two axles of the bus is improved into the space cabin which is formed by the framework, so the space is effectively utilized, the battery box and accessories are benefited to being quickly and conveniently changed and maintained, the weight distribution of the whole bus is also effectively improved, and the stability of the manipulation and brake directions is improved.
Description
Technical field
The utility model relates to a kind of setting of electric powered motor drive system, particularly a kind of structure setting of pure electronic light bus power-driven system.
Background technology
Pure electric coach is made up of vehicle body, interior trim, lithium ion battery, air-conditioning, electrical equipment, trailing wheel and back bridge system, front-wheel and preceding bridge system, power steering system, meter system, motor and speed change system, air-channel system, chassis.Pure electric coach is because the base plate lower space is limited, and battery pack quantity is many, and it is big to take up room, and brings very big difficulty for the overall setting of car load.At present, domestic and international similar vehicle chassis all is to adopt whole straight frame and motor preposition back-wheel drive basically, and lays battery box at interior; Cause the drive of motor route long thus, distribution of axle load is unreasonable, and structure is not compact; After vehicle's center of gravity is inclined to one side, influence road-holding property; Rear deck is taken by battery, causes annexes such as air pump, air-conditioning compressor to disperse to lay, and riding space also is compressed, and car load space utilization efficient is low; And its power system structure and vehicle body complex process, manufacturing cost is high, maintenance difficulty etc.
The utility model content
The purpose of the utility model is to the deficiency of above-mentioned existing pure electronic light bus, and a kind of structure setting of pure electronic light bus power-driven system is provided.
Its technical scheme is: a kind of structure setting of pure electronic light bus power-driven system; It is characterized in that; Drive motor is laid on the vehicle frame of automobile axle back, and the drive motor axle directly or through change/retarder connects transmission shaft, and transmission shaft is through the rear-axle drive trailing wheel; Battery box and accessory system evenly are laid in the cabin, space that is made up by framework between the car load antero posterior axis.
Its beneficial effect is: the utility model makes drive motor near trailing wheel owing to adopt the rearmounted back-wheel drive of drive motor, drives nearby, thereby makes its compact conformation, and drive path is short, helps improving driving efficiency; To have simultaneously that the unit frame crossbeam is improved to the cabin, space that is made up by framework between the diaxon of passenger vehicle now; Actv. has utilized the space; Be used for evenly laying electrokinetic cell and annex etc., change fast, easily and safeguard that also actv. has improved the distribution of weight of car load thereby promptly help battery box and annex; The stability of manipulation and the stability of braking direction have been improved; Can also make the interior space more spacious, improve traveling comfort and the compartment space availability ratio taken, be very suitable for pure electronic light bus.
Description of drawings
Fig. 1 is the integral structure scheme drawing of the utility model;
Fig. 2 is the birds-eye view after Fig. 1 removes the compartment.
The specific embodiment
Like Fig. 1, shown in Figure 2; The structure setting of pure electronic light bus power-driven system; Drive motor 4 is laid on the vehicle frame of automobile axle back, and the drive motor output shaft directly or through change/retarder is connected with transmission shaft 3, and transmission shaft is through rear-axle drive trailing wheel 2.Battery box and accessory system evenly are laid in the cabin, space 1 that is made up by framework between the car load antero posterior axis.
Claims (1)
