Abstract

The utility model discloses a simple two-axis type power coupling transmission. On the basis of the conventional two-axis type transmission, a pair of motor driving and driven gears are additionally arranged; the gears are connected with driving and driven shafts through bearings and separation mechanisms; and functions of hybrid driving, independent driving, parking power generation or starting, power compensation, gear shifting and the like of an engine/motor can be achieved in different speed ratio by changing the state of the separation mechanism. The simple two-axis type power coupling transmission has the beneficial effects that a most flexible power coupling route is achieved by only slightly changing the part structure of the conventional transmission, the process succession with the conventional gearbox is good, and the transmission can be widely in various power equipment of automobiles, track vehicles, vessels, engineering machines, agriculture machines, and the like.

Description

A kind of simple and easy two-axis power coupling speed changer

[technical field]

The utility model relates to that power transmission system, particularly gear subtract, speed change gear, motor vehicle driven by mixed power, have three and above power source and retarder, the speed changer of load, can be widely used on the various power equipments such as automobile, rail vehicle, boats and ships, engineering machinery, farm machinery.

[background technique]

At present, due to the pressure of energy-saving and emission-reduction, automobile energy-saving reduces discharging standard increasingly stringent.In order to reduce the energy consumption of vehicle, the numerous new vehicle systems that comprise hybrid vehicle have been developed.Hybrid vehicle, as having the long mileage of traditional combustion engine vehicle and electric automobile energy saving, environmental protection concurrently, can be used the vehicle class of clean electric energy to start to be widely used.Also have some vehicles in order to guarantee reliability, the Economy of vehicle and to reduce manufacture cost etc. simultaneously, there is plural power source.For example there are some special purpose vehicles, engineering machinery, super sized type vehicle, special safety vehicle of assistant engine etc.These vehicles all need one by the power coupling in two above different dynamic sources, jointly or respectively drive system---the dynamic coupling system of vehicle.The requirement of dynamic coupling system is the power of plural power source output to be delivered to separately respectively on output unit to (as wheel etc.), can the power of plural power source output is delivered on output unit simultaneously again; And for motor vehicle driven by mixed power except above-mentioned functions, also must be by the power of a power source output, be delivered to another one power source (being generally motor) upper, and guarantee not to be passed on output unit simultaneously, to realize the functions such as generating of stopping.

But current can realize above-mentioned functions dual power source dynamic coupling system, mainly comprise following several form:

1 adopts planetary pinion coupled modes.Typical case application comprise Toyota general sharp this, the automobile such as general fertile Lan Da;

2 adopt angle transmission speed variator.Typical case's application comprises Nan Che group hybrid power passenger car;

3 adopt coaxial coupling, are about to motor and are arranged on motor Transmitted chains, rely on plural clutch to realize different output modes.

But there are the following problems for current coupled system:

Mode 1 pair of planetary pinion processing, assembly precision require high, and transmission efficiency is low, bad with the production technology inheritance of existing vehicle drive system, needs used device, mould etc. again.

Mode 2 adopts bevel gear tooth system high to Gear Processing required precision, lubricated difficulty etc.

Mode 3 exists two power source speed to be fixed, and is difficult to bring into play the problems such as optimum-curve for operation of each power source

The utility model can solve the problems referred to above of dual power source dynamic coupling system.

[summary of the invention]

The technical problems to be solved in the utility model be to provide a kind of can be by retarder or the speed changer of the power flexible communication of three above power sources or load, can also make full use of existing speed changer manufacturing mechanism, technique, part simultaneously, to reduce to greatest extent the first input cost of system, and the simplification of implementation structure.

In order to solve the problems of the technologies described above, the technological scheme that the utility model is taked is: input shaft (1), casing (2), separating mechanism (4), motor driving gear (5), bearing (6), motor driven gear (7), shifting gear secondary (8), gearshift (9) output shaft (10), it is characterized in that: by bearing (6), input gear (5) is installed input shaft (1) is upper, between input gear (5) and input shaft (1), can or be communicated with transmission of power by separating mechanism (4) cut-out; Bearing (6) and separating mechanism (4) are also installed between the motor driven gear (7) being meshed with motor input gear (5) and output shaft (10).

Be exactly in brief on conventional art twin-shaft transmission between the main driven gear of a pair of shifting gear wherein and corresponding axis, all to install bearing and separating mechanism.The state that changes separating mechanism can realize motor/motor with different speed ratio combination drives, generating or start and the function such as power compensation gearshift drives separately, stops.

The beneficial effects of the utility model are only to change on a small quantity the design of part of traditional speed changer, just can realize power coupling path the most flexibly, the power interruption when can realize the multiple drive modes of single motor and under automatic controlled conditions, AMT being shifted gears compensates and realizes dynamic gearshift.

The utility model can be widely used on the various power equipments such as automobile, rail vehicle, boats and ships, engineering machinery, farm machinery.

[embodiment]

With an instantiation, introduce embodiment below, actual embodiment is not limited to this example.

Accompanying drawing 1 is the structural configuration sketch of a kind of simple and easy two-axis power coupling speed changer of the utility model.Engine power can be inputted from A by clutch.Input shaft (1) will be with engine rotation.Motor power can pass through gear, from the B of casing (2), be meshed with motor driving gear (5), and by motor driven gear (7) and be arranged on motor driven gear (7) and output shaft (10) between separating mechanism (4) be delivered on output shaft (10), the power of motor and motor converges output through different speed ratios on output shaft (10), can realize the different speed ratio combination drives of motor and motor; The state that changes separating mechanism (4) and gearshift (9), can also be connected motor driving gear (5) with input shaft (1), motor and motor power converge on input shaft.Now, when gearshift (9) is all separated, can realizes the transmission of power between motor and motor, and not to wheel output, can realize stopping for charging function or the electric motor starting duty of engine.At gearshift (9) during in conjunction with 6 gear, motor and motor can be realized input shaft to the identical speed ratio combination drive between output shaft.

Accompanying drawing 2 is in the embodiment shown in accompanying drawing 1, has increased reverse gear (3) and motor driving gear (5) is changed into multilayer gear and uses accordingly a plurality of motor driven gears on scheme basis shown in accompanying drawing 1.Do like this and can realize mechanical car-backing function, the transmission speed ratio of motor is more easily optimized simultaneously.
