Problems solved by technology

At present, the surface where the floating sleeve of the controllable one-way device is in contact with the friction plate is a plane, and it is a plane contact when working. It is found in practical applications that it is relatively easy to slip, unreliable, and the phenomenon of jumping gears or not shifting often occurs; at the same time The working surface of the cam of the controllable one-way device is arc-shaped, which is unreliable in use and easy to slip, and the shape of the working surface is complicated, which is difficult to process, high in cost, and difficult to control in quality

Abstract

The invention discloses an overrunning device and relates to an electromobile output shaft assembly. The overrunning device mainly comprises a controllable isolator, wherein the controllable isolator comprises a solenoid valve, friction plates, a floating sleeve, a cam and pin rollers, and sleeves an output shaft; the friction plates of the controllable isolator are matched with the floating sleeve; meanwhile, the friction plates are also connected with a low-speed gear; the pin rollers and the cam are arranged in the floating sleeve; the cam is also in splined joint with the output shaft; at least one bulge loop with a V-shaped section is arranged on the end face, matched with the friction plates, of the floating sleeve; the bulge loops are concentrically distributed along the center of the floating sleeve; and ring grooves with the corresponding V-shaped sections are formed in the friction plates. The overrunning device has the advantages that the floating sleeve and the friction plates are matched by adopting the bulge loops and the ring grooves, and the conical surface fit is formed, so that the contact area is increased, and the friction plates and the floating sleeve cannot easily slip.

Description

technical field [0001] The invention relates to an output shaft assembly of an electric vehicle, in particular to an overtaking device for an electric vehicle. Background technique [0002] When the car engine is started, the flywheel of the engine must first be driven by the starter to rotate, and then the engine can be started; but when the engine is ignited and started, the speed of the flywheel will quickly exceed the speed of the starter, in order to prevent the engine from driving the starter in reverse Therefore, a one-way device is set between the engine and the starter, also called an overrunning clutch, so after the engine speed exceeds the starter speed, the one-way device will be separated, thereby preventing the engine from driving the starter to rotate. [0003] The electric vehicle is also provided with a one-way device; when the electric vehicle is shifted from high gear to low gear, the output shaft still has a relatively high speed because the output shaft ...
