Description

Electronlmobil brake power generating device

Technical field

The utility model relates to a kind of electronlmobil relevant equipment, particularly a kind of electronlmobil brake power generating device.

Background technology

Electronlmobil generally has various operating modes such as acceleration, deceleration and brake in the process of moving; In electronlmobil starting, acceleration and cruising process; The main takeoff output of electrical motor that relies on overcomes cruising and the acceleration that wheel and ground-surface friction force and windage are realized electronlmobil; But when running into different road conditions and parking, electronlmobil need frequently slow down or brake, and in fact deceleration and brake process are exactly to utilize brake equipment to overcome the kinetic energy of electronlmobil; And the kinetic energy that is overcome is before slowing down or braking, to give the electronlmobil car body by the energy of electrical motor output; In the time of brake or deceleration, this part energy that electrical motor is given electronlmobil will consume in vain, along with the continuous rising of China's electronlmobil recoverable amount; The annual energy that consumes in this respect is sizable, disagrees with the energy-saving and emission-reduction measure of present implementation and the construction object of low-carbon economy.

The utility model content

The utility model technical matters to be solved provides and a kind ofly can be effectively the kinetic energy in electronlmobil brake or the moderating process be converted into electrical power storage, and can shorten the electronlmobil brake power generating device of electronlmobil brake or moderating process.

The design concept of the utility model is to realize like this; The drag of existing electronlmobil and moderating process are actually to be utilized brake equipment to consume gradually or reduces electronlmobil kinetic energy and reduce electronlmobil speed; And in deceleration and brake process, still need consume a part of electric energy; The utility model is through setting up power generation assembly on the electronlmobil brake equipment; Brake disc in electronlmobil cruising process in power generation assembly and the brake equipment is in released state, and the input gear of power generation assembly is meshed with the brake disc that is provided with engaging tooth when needs slow down or brake, and the kinetic energy of electronlmobil is converted into electrical power storage in storage battery in the time of will braking on the one hand; Promote the electronlmobil flying power; One side cutting magnetic line in the power generation assembly power generation process need overcome certain magnetic field resistance in addition, and the resistance that is produced can also provide certain braking force, shortens electronlmobil and slows down or brake process; The normal operation that the electric energy that is produced can be supplied power the electrical automobile electric system realizes purpose of energy saving.

For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of electronlmobil brake power generating device, comprise brake clamp, and also comprise brake disc and power generation assembly; Be evenly equipped with engaging tooth on the said brake disc circumference; Said power generation assembly comprises electrical generator, magnetic clutch, input gear and controller; The power generation assembly front end is captiveed joint with the caliper shell side and its input gear stretches in the caliper shell, and input gear is connected with the electrical generator input shaft through magnetic clutch.

Adopt the beneficial effect that technique scheme produced to be: with the supporting power generation assembly that is provided with of brake equipment, in the electronlmobil normal course of operation, power generation assembly and brake equipment are in disengaged position; Do not influence the normal takeoff output of electronlmobil; When electronlmobil need slow down or brake, through sensor and its input gear of controller control and the brake disc engagement that is provided with engaging tooth, electronlmobil kinetic energy produced electric energy through the rotation driven generating set of brake disc on the one hand; And electric energy imported battery stores; Promote the electronlmobil flying power, in addition on the one hand, in power generation process, need overcome the resistance of magnetic line of force; Just brake disc drags in the power generation assembly power generation process and need overcome certain resistance; This resistance can constitute braking force jointly with the friction force of brake clamp and brake disc, can effectively shorten electronlmobil and slow down or brake process, realizes the purpose of energy-saving and emission-reduction.
