Description

Variable speed ratio hybrid power driving system for mining truck
Technical Field
The invention belongs to the field of new energy transmission systems, and particularly relates to a variable speed ratio hybrid power driving system for a mining truck.
Background
Chinese patent ZL201510661702.9 discloses a pure electric drive axle system for underground heavy-load mining vehicles, which comprises a battery pack, a controller, a motor, a two-gear planetary gear type transmission, a main speed reducer, a differential, a wheel-side speed reducer and a drive axle housing. The motor is positioned at the initial end of the driving system, and energy is sourced from the battery pack; the two-gear planetary gear type transmission is of a single-stage planetary gear row structure, and the power transmission direction is changed through an internal clutch to generate different transmission ratios; the main speed reducer and the differential are in a traditional bevel gear structure; the wheel reduction gear is of a two-stage planetary gear row structure and is connected with the differential mechanism through a high-speed stage sun wheel shaft; the brake and the hub reduction gear adopt an integrated structure, and braking force is generated by braking the secondary sun gear.
However, the single-travel distance and the operation time of the pure electric drive axle system are limited, and the pure electric drive axle system is not suitable for the long-time high-load operation of the mining truck.
In addition, the power and/or torque of the motor of the current mining truck are high in requirement, so that the size and the self weight of the motor are large, and a large space is occupied. For the actual working conditions of various domestic large mining areas at present, the low-speed electric drive of the whole vehicle and the downhill braking energy recovery of a large load cannot be realized, so that the operation cost of the whole vehicle is higher.
Accordingly, there is a need for a mining truck variable ratio hybrid drive system that addresses one or more of the above-identified technical problems.
Disclosure of Invention
To solve at least one of the above technical problems, according to an aspect of the present invention, there is provided a mining truck variable speed ratio hybrid drive system, characterized by comprising:
an engine;
the input end of the first clutch is connected with the engine, and the output end of the first clutch is connected with the planet carrier;
a motor including a stator and a rotor;
the planet row comprises a sun gear, a planet wheel, a planet carrier and a gear ring, wherein the gear ring is connected with the stator through the following one-way clutch, and the sun gear is connected with the rotor;
one end of the second clutch is connected with the sun gear, and the other end of the second clutch is connected with the planet carrier;
a one-way clutch; and
the input shaft of the gearbox is connected with the planet carrier;
when the second clutch is in a separated state, the gear ring is locked by the one-way clutch, and the planet carrier is connected with an input shaft of the gearbox and used as the input of the gearbox; when the second clutch is in a combined state, the one-way clutch does not brake the gear ring, and the planet carrier and the sun gear are connected with the input shaft of the gearbox to be used as the input of the gearbox.
According to still another aspect of the present invention, when the second clutch is in the engaged state, the ring gear rotates clockwise, and the one-way clutch does not perform a braking action.
According to a further aspect of the invention, the outer hub of the second clutch is connected to the planet carrier via a first connecting element, and the inner hub is connected to the sun gear via a second connecting element.
According to a further aspect of the invention, the first connection member is connected to the outer hub of the second clutch, the planet carrier, the output of the first clutch and the input shaft of the gearbox, and the second connection member is connected to the inner hub of the second clutch, the rotor and the sun gear.
According to a further aspect of the invention, the second connection member is arranged alongside the row of planets.
According to still another aspect of the present invention, the input-output speed ratio of the planetary row is the reduction ratio when the second clutch is in the disengaged state.
According to yet another aspect of the invention, the reduction ratio is 1.3-2.4.
In accordance with yet another aspect of the present invention, the input-to-output speed ratio of the planetary gear set is 1 when the second clutch is engaged.
According to still another aspect of the present invention, when the first clutch is engaged, the power of the engine is output to the transmission via the first connecting member.
According to still another aspect of the present invention, when the first clutch is disengaged, the power of the rotor is output to the transmission via the planetary row and the first coupling member.
The invention can obtain one or more of the following technical effects:
on the basis of not changing the components such as a gearbox, an engine and the like of the original mining truck, the low-speed electric drive of the whole truck is realized; the downhill braking energy recovery of the heavy load is realized; the whole vehicle operation cost is reduced; a variable speed ratio mechanism is added between the motor and the original mining truck gearbox, so that the power and/or torque requirements of the motor can be reduced, the size of the motor is reduced, and the cost is reduced; can adapt to the actual working conditions of various domestic large mining areas.
