Embodiment

[0031] Example: see figure 1 , figure 2 , image 3 and Figure 4 , a two-way controllable ratchet clutch transmission device, including a fixed shaft 1, the fixed shaft 1 can be used as a load-bearing shaft of a vehicle to support the front tire or rear tire of the vehicle, and its two ends are supported on the flat fork of the vehicle or the frame of the vehicle On the fixed shaft 1, there is an output sleeve 2 (empty sleeve), and the input gear 3 is arranged on the output sleeve 2, and is meshed with the power device (such as an electric motor, engine) through a gear, or a belt drive, or a sprocket The input gear 3 connected to the transmission can drive the output shaft sleeve 2 to rotate, and transmit the output torque of the power device to the output shaft sleeve 2 through the input gear 3, and drive the output shaft sleeve 2 to rotate; when installing, the output shaft sleeve 2 is usually connected with the vehicle The hubs of the front tires or rear tires cooperate...

Abstract

The invention discloses a two-way controllable ratchet clutch transmission device. An output shaft sleeve is sleeved on a fixing shaft in a hollow mode, an input gear is arranged on the output shaft sleeve, a plurality of tooth sockets are arranged on an inner periphery of the input gear, one or more forward ratchets and reverse ratchets are arranged inside the tooth sockets in a fit mode, forward ratchets and reverse ratchets can rotate round ratchet shafts of forward ratchets and reverse ratchets, one ends of forward ratchets and reverse ratchets can be clamped in one tooth socket of the input gear or separated from the tooth socket, a shifting sleeve which can move axially is arranged on the fixing shaft, the shifting sleeve is in inclined plane fit with lower ends of reverse ratchets, when the shifting sleeve moves axially, reverse ratchets are pushed to rotate round ratchet shafts of reverse ratchets, upper ends of reverse ratchets are exposed out of holes of the output shaft sleeve and clamped in tooth sockets of the input gear or rotate to holes of the output shaft sleeve. According to the device, reverse transmission is achieved through ratchet opening and closing, gears are not required to move axially, the structure of the device is more compact and smaller than that of a traditional primary/secondary shaft shifting system, the sliding and reserve transmission are achieved through a set of forward ratchets and a set of reserve ratchets, the drive displacement is small and the device is simple and reliable.

Description

technical field [0001] The invention relates to an engine power transmission device, in particular to a two-way controllable ratchet clutch transmission device. [0002] Background technique [0003] In the engine power transmission system, the clutch device is a very important part, which plays a very important role in ensuring the stable output power of the engine, protecting the engine components from being damaged under abnormal conditions, and ensuring the safe operation of the device driven by the engine power. The engine power transmission device in the prior art, especially the power device suitable for electric drive, such as the engine power transmission device of the electric drive walking device such as electric bicycle, electric motorcycle, etc., needs to have the following basic functions: 1) Simple structure , can not adopt complex and cumbersome power structure; 2) It can realize forward and reverse rotation smoothly, that is, it has forward gear and reverse...
