Dual-star-wheel variable-speed energy storage anti-locking transmission mechanism

Abstract

The invention discloses a dual-star-wheel variable-speed energy storage anti-locking transmission mechanism. The dual-star-wheel variable-speed energy storage anti-locking transmission mechanism is characterized in that two plane gear frames are erected on the shaft normal of a hollow spindle, the side faces of the plane gear frames and the hollow spindle are provided with a main driving planet gear set and an auxiliary driving planet gear set in a concentricity manner, planet gears of two gear sets are different in diameter and same in number, the distances between the plane gears and the center of a sun gear are equal, motors are coaxially mounted at the positions, corresponding to the plane gears, of the middles of the plane gear frames, clutches are arranged between the plane gears andshafts of the motors, hub convergence and hub convergence tires are combined into a whole from the left end and the right end of the hollow spindle to the same axis, bearings are arranged between center holes of the hub convergence and the hub convergence tires and the hollow spindle, clutches are arranged on hub rings and inner engaging gears of the plane gear sets, clutches are arranged betweenthe center holes of the hub convergence and the hub convergence tires and the sun gear shaft holes of the adjacent planet gear sets, according to the dual-star-wheel variable-speed energy storage anti-locking transmission mechanism, electric vehicle drive wheels are created and optimized from three aspects of anti-locking, energy recycling and brake hysteresis force increasing.

[0002] The practical application of CN201921246917.4 "Planetary Gear Drive Device with Specific Boss" (publication (announcement) number: CN210799911U publication (announcement) date: 2020.06.19) applied by the applicant (patent right) on August 4, 2019 A new type of patent, an innovative planetary gear drive device with a specific boss, which is a good solution to the huge radial force of the wheels, especially heavy-duty vehicles. The planetary gear mechanism is easily deformed, the gear teeth are easily damaged, and the gears of the planetary gear mechanism are also prone to damage. Axial displacement problem, the successful implementation of planetary gears directly installed in the wheel hub using the integrated hub motor wheel directly driven by the motor

[0003] The above-mentioned patents have three new technical difficulties in actual use: one is that the internal gear of the planetary gear set is directly and rigidly installed on the wheel hub, once the teeth of the planetary gear set are locked and the rotation is stopped, the entire wheel will be locked. , which is extremely dangerous when the vehicle is running at high speed; the second is that the energy recovery of electric vehicles is already a standard configuration, and the above-mentioned patent has no obvious effect on recovering energy when braking and decelerating; The hysteresis force of the motor is very small, and the deceleration and braking effects are not obvious, so it is necessary to innovate the two-stage transmission mechanism of the driving wheel of the electric vehicle to solve the above problems
