Abstract
The embodiment of the invention provides a hydraulic planetary gear speed changing device and a control method thereof. The hydraulic planetary gear speed changing device is simple in structure, low in cost, and easy to use and maintain. The hydraulic planetary gear speed changing device is composed of a planetary gear mechanism and a hydraulic adjusting mechanism. pressure is generated by a hydraulic pump, one element in the planetary gear mechanism is subjected to different constrains through pressure variation in a hydraulic loop, the rest two elements can be used as input/output elements to acquire different transmission ratios, and a corresponding speed changing effect is achieved.
Description
Technical field
The invention belongs to mechanical transmissioning technology field, is a kind of have gear automatic transimission or stepless speed changes devices and controlling method.
Background technique
To be applied as example at motor vehicle, mainly contain three kinds of forms such as hand gear (MT), automatic shifting speed-variable (AT), stepless change (CVT) at present.Wherein, MT structure complicated operation relatively simply but in use; AT speed changer is along with numbers of gear steps increases, and volume is large, complex structure, and production requirement and cost are high; CVT be take metal belt type stepless variable as main, have advantages of smooth gear shifting, but essence belongs to friction driving, driving belt is required to high, making complexity, and in using process, be prone to heating, cannot bear the larger shortcomings such as load.
Summary of the invention
The embodiment of the present invention provides a kind of have gear automatic speed changing or stepless speed changes devices and controlling method, by the shortcoming that solves above-mentioned speed change gear.And simple in structure, cost is low, be easy to use and keep in repair.
The present invention is comprised of planetary gears and hydraulic regulator two-part.Comprise:
In planetary gears, by elements such as input shaft, sun gear, gear ring, planetary pinion, planet carrier, driven gears, formed.Wherein, driven gear and sun gear, gear ring, planet carrier one of them be connected.Hydraulic regulator consists of driving gear set, oil hydraulic pump, energy storage canister, valve, liquid container, control unit, auxiliary lock stop element etc.
With the sun gear in planetary gears, gear ring, planet carrier one of them, by driven gear, be connected with the driving gear set of hydraulic regulator, drive oil hydraulic pump in oil hydraulic circuit, to produce pressure.If valve opening is less or close, the rising of oil hydraulic circuit pressure, the corresponding increase of working load of oil hydraulic pump, the transmission resistance increment that the driven gear in planetary gears is subject to thereupon, the constraint that the element being connected with driven gear in planetary wheeling mechanism is subject to increases.
[0006] in planetary gear mechanism, if sun gear, gear ring, planet carrier wherein two elements as input and output shaft, to the 3rd element in addition different constraints just can obtain different velocity ratios, reach corresponding speed changing effect.
Accompanying drawing explanation
The structure diagram of the speed change gear that Fig. 1 provides for embodiments of the invention; In figure: 1, input shaft 2, output shaft 3, sun gear 4, ring gear 5, planetary pinion 6, planet carrier gear 7, driven gear 8, driving gear set 9, oil hydraulic pump 10, energy storage canister 11, valve 12, liquid container 13, control unit 14, auxiliary lock stop element;
Fig. 2 is working conditions change relation table (is connected with planet carrier with follower, supposes that input speed and output load do not become example);
Sun crop rotation only take below as input element, and gear ring is as output element, and the constraint that planet carrier is carried out in various degree illustrates the technical program.
Overall outline: input shaft (1), by planetary pinion (5) and ring gear (4) engagement, is connected with output shaft (2).The planet carrier that is used for installing planetary pinion (5) exists with the formation of gear, i.e. planet carrier gear (6).Planet carrier gear (6) is linked in sequence with driven gear (7), driving gear set (8), to oil hydraulic pump (9), provides power.Oil hydraulic pump (9), energy storage canister (10), valve (11), liquid container (12) form oil hydraulic circuit; Hydraulic coupling size between oil hydraulic pump (9) and valve (11) is regulated by control unit (13).When auxiliary lock stop element (14) locking, speed changer is exported fixing velocity ratio.
Active force is transmitted: power inputs to sun gear (3) from input shaft (1), by planet wheel (5) and ring gear (4) to output shaft (2), outputting power.
Output speed regulates: when power is when inputing to sun gear (3), and can be from planet carrier gear (6) and ring gear (4) output.When planet carrier gear (6) is fixedly time, institute is dynamic to export from ring gear (4).Otherwise, during the dynamic output of planet carrier gear (6), from the power of ring gear (4) output, reduce.Planet carrier gear (6) provides power by driven gear (7), driving gear set (8) to oil hydraulic pump (9) simultaneously.Oil hydraulic pump (9) is to hydraulic oil acting, and when valve (11) aperture is less or close, the hydraulic coupling between oil hydraulic pump (9) and valve (11) rises, and it is large that the resistance that oil hydraulic pump (9) need to overcome becomes.Driven gear (7) and planet carrier gear (6) rotating speed decline, and ring gear (4) output speed rises thereupon.When valve (11) aperture becomes large or standard-sized sheet, hydraulic coupling between oil hydraulic pump (9) and valve (11) declines, the resistance force diminishes that oil hydraulic pump (9) need to overcome, driven gear (7) and planet carrier gear (6) rise of rotational speed, ring gear (4) output speed declines thereupon.Therefore the aperture of control valve (11) size, just can control planet carrier gear (6) output speed, and the rotating speed of ring gear (4) output simultaneously also corresponding variation can occur.
When valve (11) is chosen continuously adjustable variable valve, can realize stepless change; When valve (11) is chosen the valve group of a plurality of single valves compositions in parallel, can realize many shift automatic variable speeds.
