Problems solved by technology
[0006] 1. The gripping mechanism and the clutch limit the initial rotation angle of the clutch through friction, thereby increasing the wear of the gripping mechanism and the clutch joint area, thereby increasing the probability that the gripping mechanism and the clutch need to be replaced due to wear, and, The friction formed between the two will be reduced due to long-term use, and the initial rotation angle limit may fail
[0007] 2. The above method has the problem of response lag, that is, when the initial angle of the clutch rotation is or has been greater than the maximum allowable angle, the clutch mechanism cannot completely limit the rotation of the clutch
This stems from the inability of the mechanism powering the clinging mechanism to provide timely power
For example, when an electromagnetic mechanism is used to provide power for the clamping mechanism, it takes a certain amount of time for the electromagnetic coil to build up enough electromagnetic force; It takes a long time to build up, or the fluidity of the hydraulic oil is high due to its high viscosity), so that when the power mechanism is started, it cannot provide timely and sufficient power for the holding mechanism

Embodiment Construction
[0052] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0053] Such as Figures 1 to 9 As shown, the embodiment of the present invention discloses a power coupling mechanism 300 that can be combined with the transmission mechanism at least when the power mechanism 100 is activated. The coupling mechanism 300 specifically includes the clutch 10, the gear bar 30 and the force applying mechanism 20. Clutch 10 is coaxially connected with the power shaft 101 of power mechanism 100 to realize the synchronous rotation with power shaft 101, for example, clutch 10 rotates synchronously with the output shaft of the motor as power mechanism 100, in the present invention, as Figures 1 to 3As shown, the clutch 10 is provided with a combined end surface, and a section of stop groove 11 extending ...

The invention discloses a power combination mechanism. The power combination mechanism comprises a clutch, a stop rod and a force applying mechanism, wherein the clutch is mounted on a power shaft ofa power mechanism, the clutch is provided with a combination end surface, and a section of backstop grooves extending in the circumferential direction are formed in the combination end surface; and the force applying mechanism is used for applying force to the stop rod so as to enable the head of the stop rod to at least be located in the backstop grooves started by the power mechanism and to be stopped by the groove walls of the backstop grooves. According to the power combination mechanism, abrasion condition does not exist, and the problem of hysteresis quality limited by a rotation angle of the power shaft due to establishing time problem of the force cannot be brought.
Description
technical field [0001] The invention relates to the technical field of automobile transmission, in particular to a combination mechanism for power transmission. Background technique [0002] The power-train is an important component of mobile equipment, such as automobiles and, in particular, specialty vehicles, which is used to power work implements. For example, rotary tillage machines all have the above-mentioned system. The power-transmission system usually includes a power mechanism, a transmission mechanism and a combination mechanism connecting the power mechanism and the transmission mechanism. Among them, the power mechanism, such as an engine, is used to provide power; the transmission mechanism is used to transmit the power of the power mechanism to the working device; the coupling mechanism includes a clutch and its components, which are used to make the power mechanism and the transmission mechanism selectively combined. [0003] For some equipment, when the ...
