Abstract
The utility model provides a dual-power tractor which is provided with two sets of mutually independent power systems. A front axle is driven by a diesel engine, and a rear axle is driven by electric power; a rear driving axle system structurally comprises an electricity storage device (1), a motor controller (6), a motor (9), a rear axle assembly (10) and a motor clutch (11), wherein the electricity storage device (1), the motor controller (6) and the motor (9) are connected by using conducting wires; a rotating shaft of the motor (9) is connected with a drive gear shaft (3') of the rear axle assembly (10) through the motor clutch (11); and the motor (9) is structurally integrated with the rear axle assembly (10). The dual-power tractor has the outstanding advantages that when the tractor runs under a light load, one set of power system can be independently used, so that energy sources are saved; when the tractor runs under a high load, the two power systems can be used at the same time, so that the problem of insufficient grade capability of the tractor can be solved; when the tractor is braked, the motor is converted to an electricity generator, so that the tractor speed can be reduced, the electricity storage device can be charged, and abrasion reduction of braking pieces and tires and the improvement of driving safety performance are facilitated.
Description
Technical field
The utility model relates to a kind of trac. parts.
Background technology
At present, trac. is major impetus with the diesel engine still, along with fuel price rises steadily, has caused the continuous rising of operating cost.Though also the someone has manufactured experimently pure battery-powered tractor, under the current techniques condition, it is promoted the use of and is still waiting time.Therefore, as transition period, use double dynamical trac. to tally with the national condition.Move when the underload like trac., can use pure diesel or pure electronic, when trac. moves during at high load capacity, can use the diesel-engined drive propons, the direct motor drive back axle thoroughly improves the hill climbing ability of trac..Do like this and not only improved operating efficiency, reduced operating cost, realized energy-saving and emission-reduction.Also improved driving safety.
Summary of the invention
The propons of the utility model is used diesel-engined drive, and back axle is used motor-driven, and two cover power systems are separate.The rear driving axle system adopts electrical storage device (comprising various batteries and ultracapacitor), electric machine controller, motor and rear driving axle, makes motor and back axle integrated on the structure.This back axle has deceleration and electric braking energy recovery function.
The technical scheme of the utility model is following:
Comprise electrical storage device, electric machine controller, lead, motor and back axle assembly in its structure, between electrical storage device and the electric machine controller, be connected with lead respectively between electric machine controller and the motor.Motor is installed on the housing of back axle assembly, and the rotating shaft of motor links through the driving gear shaft of electric motor clutch and back axle assembly.
There are housing, driving gear, driving gear shaft, driven gear, differential assembly to be installed in the housing in the structure of back axle assembly.Driving gear and driving gear shaft are used key connecting, driven gear and differential assembly housing bolt together.
The advantage of the utility model:
1, disposed the separate power system of two covers, when under the trac. underload, moving, selected feelings and use a cover power system wherein.When under the trac. high load capacity, moving, use two cover power systems simultaneously, can satisfy the multiple operating needs of trac..
2, in the deboost phase, the operating electrical machines controller makes motor convert electrical generator into.Be the electrically-charged while of electrical storage device, bringing into play the function of retarder again.Aspect energy-saving and emission-reduction, reduction component wear, the raising driving safety good effect is being arranged all.

The working process of the utility model is following;
1, in the rear-axle drive stage; Electrical storage device (1) is supplied power to electric machine controller (6) through lead (2), (3); Electric machine controller (6) is according to driver operation, and to motor (9) power supply, motor (9) advances through electric motor clutch (11) driving rear axle assembly (10) through lead (7), (8).Motor this moment (9) is electric motor state.
2, in the back axle deboost phase, electric machine controller (6) converts motor (9) into the electrical generator state according to driver operation.Back axle assembly (10) is sliding under the power effect, drives motor (9) rotation through electric motor clutch (11), and the electric current that motor (9) sends flows into electric machine controller (6) through lead (7), (8), charges to electrical storage device (1) through lead (4), (5) again.At this moment, motor (9) is the electric braking state.
