power combination mechanism

Abstract

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 part of mobile equipment, such as automobiles, and more specifically, special-purpose vehicles, which is used to power work equipment. 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 ...

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 sufficient electromagnetic force; It takes a long time to build up, or the fluidity of the hydraulic oil is high due to its high viscosity), which makes it impossible to provide timely and sufficient power for the holding mechanism when the power mechanism is started.
