Description
Technical Field
The present invention relates to a transmission including a variable speed motor, and more particularly to a planetary gear transmission and an electric vehicle equipped with the planetary gear transmission.
Background
At present, an energy recovery electric vehicle is gradually applied, the energy recovery is that a driving motor is instantly changed into a generator to generate electricity when the electric vehicle goes downhill, the resistance of the electricity generation is utilized to assist braking, and the generated electricity is utilized to prolong the endurance mileage. Because the generator has certain rotating speed requirement when generating electricity, so the energy recovery electric vehicles on the market all adopt brushless toothed motors, but in order not to influence the sliding of the electric vehicle, the brushless toothed motors are additionally provided with one-way clutches on planetary gear speed changers in the brushless toothed motors, namely, the motors can only drive hubs to rotate, and the hubs cannot drive the motors to rotate.
Disclosure of Invention
The invention aims to solve the technical defects and provide a speed changer which can enable a hub to drive a motor to rotate according to requirements and can also cut off the speed changer which does not enable the hub to drive the motor to rotate according to requirements and an electric vehicle provided with the speed changer.
In order to achieve the purpose, the invention adopts the following technical scheme.
At least one brake caliper is mounted on the housing of the transmission, such that the brake caliper brakes the planet carrier directly or via a brake disk. When the planet carrier is braked by means of a brake caliper via a brake disc, the brake disc is fixedly assembled with the planet carrier.
The invention has the advantages.
The brake does not affect sliding, can assist the braking of the motor, can drive the motor to generate electricity, reduces the friction of the brake pad, and improves the safety of the vehicle when the vehicle runs down a long slope.
Drawings
The present invention will be further described in detail with reference to the accompanying drawings and embodiments.
Fig. 1 is a perspective view of the transmission of the present invention.
FIG. 2 is a perspective cross-sectional view of the transmission of the present invention.
Fig. 3 is an exploded perspective view of the brake caliper of the transmission of the present invention braking the carrier via the brake disk.
In the figure, a shell (1), a brake caliper (2), an outer gear ring rotating shaft (3), a sun gear transmission shaft (4), a brake disc (5), a sun gear (6), a planetary gear (7), an outer gear ring (8) and a planetary gear carrier (9).
Detailed Description
Unless defined otherwise, technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The motor mentioned in the text is a driving motor, is a power generation motor, and is a motor capable of generating and driving power. Electric vehicles referred to herein include electric bicycles, electric motorcycles, and electric automobiles.
At least one brake caliper (2) is arranged on a housing (1) of the transmission, and the brake caliper (2) brakes a planet carrier (9) directly or via a brake disc (5). When the brake caliper (2) is used for braking the planet carrier (9) through the brake disc (5), the brake disc (5) and the planet carrier (9) are fixedly assembled.
The brake caliper (2) is the caliper (2) of the existing automobile brake, and the hydraulic pump is used for pushing the piston to enable the brake pad to clamp or press the brake disc (5) to prevent the brake disc from rotating, so that the principle is similar and is not detailed.
The brake caliper (2) is controlled by a pedal or a handle through a brake line or a hydraulic oil pipe, when the electric vehicle needs motor power generation auxiliary braking when going downhill, the pedal or the handle controls the brake caliper (2) to brake the planet gear carrier (9) to enable the planet gear carrier not to rotate, according to the characteristics of a planetary gear transmission, the outer gear ring (8) transmits energy to the sun gear (6) through the planet gear (7), the sun gear (6) drives the motor rotor to rotate, and the motor rotates at a high speed under the driving of the hub and enables the motor to generate power.
The best embodiment of the application is that a sun gear (6) in the speed changer is in transmission connection with a motor rotor through a sun gear (6) transmission shaft (4), an outer gear ring (8) is in transmission connection with a hub through an outer gear ring (8) rotation shaft (3) through a transmission shaft, a chain or a belt, and the transmission separation between the hub and the motor is realized by using a braking planet gear carrier (9).
