Problems solved by technology

At present, the contact surface of the floating sleeve of the controllable one-way device and the friction plate is a plane, and it is a plane contact during operation. It is found in practical applications that it is relatively easy to slip, unreliable, and often occurs gear skipping or non-shifting.

Embodiment Construction

[0014] The present invention will be described in further detail below by means of specific embodiments:

[0015] The reference signs in the accompanying drawings of the specification include: encircling one-way device 1, output shaft 2, low-speed gear 3, solenoid valve 11, housing 12, friction plate 13, cam 14, roller 15, ring body 16, spring 17 , Iron core 111.

[0016] The embodiment is basically as attached figure 1 As shown: the encircling one-way device 1 includes a housing 12, a solenoid valve 11, a friction plate 13, a ring body 16, a cam 14 and a roller 15; wherein the friction plate 13 is tile-shaped, and the friction plate 13 is evenly inlaid There are iron blocks, so that it can be attracted by magnets; there are four friction plates 13, and a chute is provided on the housing 12, and the two ends of the friction plates 13 are inserted into the chute on the housing 12, so that the friction plates 13 are all aligned with the The housing 12 is slidably connected, an...

Abstract

The invention discloses an encircling overrun clutch and relates to an output shaft assembly of an electric vehicle; the encircling overrun clutch comprises a housing, an electromagnetic valve, friction plates, a ring, a cam and a pin roller; the ring is a cast iron part and in a circular ring shape; the cam and the pin roller are mounted within the ring; the cam is provided with six working surfaces and the pin roller is located between an inner surface of the ring and the working surfaces of the cam; the friction plates are tile-shaped and iron blocks are uniformly inlaid in each friction plate; at least two friction plates are provided and all connected with the housing in a sliding manner, and all the friction plates encircle into a cylindrical shape; the ring is mounted in the housing and located in the middle of the cylinder encircled by the friction plates; an iron core of the electromagnetic valve is connected with the ring; the friction plates of the encircling overrun clutch are in cambered surface contact with the ring, and therefore, a good contact effect is achieved, and a relatively large contact area is produced; as a result, the friction plates and the ring are not prone to slide, and therefore, the encircling overrun clutch has relatively high reliability; furthermore, a phenomenon of trip stop or shifting failure can be effectively avoided.

Description

technical field [0001] The invention relates to an output shaft assembly of an electric vehicle, in particular to an encircling one-way device of the 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 outpu...
